Description

Technical Field

[0001] This invention relates to the field of insulating flame-retardant fire extinguishing agent preparation technology, and in particular to an insulating flame-retardant fire extinguishing agent and its preparation method. Background Technology

[0002] Insulation refers to a material that possesses extremely high resistivity and breakdown strength at both normal and high temperatures, preventing the passage of electric current. Flame retardancy refers to the ability of the extinguishing agent itself and the surface to which it is applied to, when encountering an ignition source, to inhibit the thermal decomposition of the polymer substrate, delay the spread of flames, and promote the formation of a char layer, significantly reducing the temperature, heat release rate, and smoke density of the fire, achieving self-extinguishing or preventing sustained combustion. An extinguishing agent is a substance that can rapidly extinguish flames through cooling, suffocation, isolation, or chemical inhibition.

[0003] Traditional dry powder fire extinguishing agents primarily rely on chemical inhibition of the combustion chain reaction and the asphyxiation effect of oxygen dilution to extinguish fires. However, these agents have a limited extinguishing effect and cannot provide lasting flame-retardant modification to the residual polymer matrix. Therefore, even after the fire source is removed or the extinguishing agent is depleted, the protected object remains highly flammable, leading to a significant risk of reignition. Furthermore, traditional dry powder is prone to forming conductive paths in high-voltage electric fields, generating leakage currents and exhibiting insufficient insulation performance, severely limiting its safe application in fires involving energized equipment. Therefore, achieving stable quality and safe, environmentally friendly production of fire extinguishing agents is an urgent technical challenge. Summary of the Invention

[0004] This invention provides an insulating flame-retardant fire extinguishing agent and its preparation method, as well as a computer-readable storage medium. Its main purpose is to improve the intelligence level of high-temperature testing of titanium rods and reduce the excessive consumption of time and human resources.

[0005] To achieve the above objectives, the present invention provides an insulating flame-retardant fire extinguishing agent and its preparation method, comprising:

[0006] Receive the instruction to prepare the insulating flame-retardant extinguishing agent, and confirm the preparation materials and preparation device according to the instruction. The preparation materials include: ethanol solution, diluent, curing agent of the same mass, sodium alginate and deionized water. The preparation device includes: multiple empty beakers, sample mold set and volumetric flasks.

[0007] To obtain the optimal mass ratio, weigh out the ammonium polyphosphate powder, pentaerythritol powder, and lignin powder according to the optimal mass ratio.

[0008] Bio-based intumescent flame retardant component powders were prepared based on ammonium polyphosphate powder, pentaerythritol powder and lignin powder; sodium alginate solution and ferric chloride crosslinking solution were prepared based on sodium alginate and deionized water.

[0009] Gel particle sets were prepared based on sodium alginate solution and ferric chloride crosslinking solution, and catalytic carbonization synergistic component powder was obtained from the gel particle sets.

[0010] An insulating flame-retardant fire extinguishing agent was prepared based on bio-based intumescent flame-retardant component powder and catalytic char-forming synergistic component powder, and the preparation of the insulating flame-retardant fire extinguishing agent was completed based on the insulating flame-retardant fire extinguishing agent.

[0011] Optionally, obtaining the optimal mass ratio includes:

[0012] Obtain epoxy resin of the same mass and add it into multiple empty beakers to obtain multiple beakers to be preheated.

[0013] Each of the multiple beakers to be preheated was preheated in a water bath using a preset preheating time, resulting in multiple preheated beakers.

[0014] Set an initial experimental ratio set, extract the initial experimental ratios sequentially from the initial experimental ratio set, and obtain the formulation intumescent flame retardant based on the extracted initial experimental ratios;

[0016] The mixture to be stirred is initially stirred to obtain a viscous paste mixture. The viscous paste mixture is then diluted with a diluent to obtain a diluted mixture. The diluted mixture is then stirred at high speed to obtain the material to be ground.

[0017] Based on the material to be ground, a set of performance test values ​​is obtained, and the set of performance test values ​​is summarized to obtain a set of performance test values ​​corresponding to the initial experimental ratio set. The initial experimental ratio and the set of performance test values ​​correspond one-to-one.

[0018] Extract performance test value groups sequentially from the performance test value group set, calculate the comprehensive performance test value based on the extracted performance test value groups, and summarize the comprehensive performance test values ​​to obtain the comprehensive performance test value set;

[0019] The maximum comprehensive performance test value is determined based on the comprehensive performance test value set, and the initial experimental ratio corresponding to the maximum comprehensive performance test value is taken as the optimal mass ratio.

[0020] Optionally, the acquisition of the performance test value set based on the material to be ground includes:

[0021] The material to be ground is subjected to multiple grinding operations to obtain ground material. The same mass of curing agent is then added to the ground material to obtain cured ground material.

[0022] The solidified grinding material is stirred to obtain a stirred mixture. The stirred mixture is then subjected to a vacuum degassing operation to obtain a degassed material.

[0023] A deaerated material sample set is extracted from the deaerated material, and a casting template mold set is obtained based on the deaerated material sample set and the template mold set. The template mold set includes: oxygen index spline mold, vertical combustion spline mold and cone calorimeter template mold.

[0024] The casting sample molds are extracted sequentially from the set of casting sample molds, and a curing operation is performed on the extracted casting sample molds to obtain the cured sample molds. The state of the cured sample molds is adjusted to obtain the composite material sample to be tested.

[0025] The composite material samples to be tested are compiled to obtain a sample set of composite materials to be tested, which includes: flame retardant performance test samples, mechanical performance test samples and thermal stability test samples;

[0030] Performance test value groups were determined based on limiting oxygen index, vertical combustion rating, peak heat release rate, total heat release, tensile strength, flexural strength, and residual carbon content.

[0031] Optionally, the step of calculating the comprehensive performance test value based on the extracted performance test value set includes:

[0032] Based on the set of performance test values, the maximum extreme oxygen index, minimum peak heat release rate, minimum total heat release, maximum tensile strength, maximum flexural strength, and maximum char rate were determined.

[0033] The target limiting oxygen index, target vertical combustion rating, target peak heat release rate, target total heat release, target tensile strength, target flexural strength, and target char rate were confirmed from the extracted performance test value set.

[0034] The flame retardant performance score is calculated based on the measured value of the target limiting oxygen index, the maximum limiting oxygen index value, the target vertical burning rating, the target peak heat release rate, the target total heat release, the minimum peak heat release rate, and the minimum total heat release.

[0035] The mechanical property score is calculated based on the target tensile strength, target bending strength, maximum tensile strength, and maximum bending strength.

[0036] The thermal stability score is calculated based on the maximum char rate and the target char rate. The flame retardant performance score, mechanical performance score and thermal stability score are weighted and summed to obtain the comprehensive performance test value.

[0037] Optionally, the preparation of bio-based intumescent flame-retardant component powder based on ammonium polyphosphate powder, pentaerythritol powder, and lignin powder includes:

[0038] Ethanol solution, ammonium polyphosphate powder, pentaerythritol powder and lignin powder were introduced into a three-necked flask to obtain the solution to be mixed.

[0039] Simultaneous stirring and heating are performed on the mixed solution to obtain the initial temperature and the initial mixed solution. When the initial temperature is within the preset sufficient reaction temperature range, the stirring time is obtained by taking the time when the initial temperature is within the preset sufficient reaction temperature range as the starting point and recording the time in real time.

[0040] When the stirring time is equal to the preset continuous stirring time, the stirring is stopped on the initial mixed solution to obtain the reaction mixed solution. The reaction mixed solution is then cooled to obtain the cooled mixed solution.

[0041] The cooled mixed solution was filtered to obtain the separated solid product;

[0042] The separated solid product is washed multiple times to obtain a purified solid product, which is then dried to obtain a dried solid product.

[0043] The dried solid product is ground to obtain an initial ground powder, which is then sieved to obtain a fine powder. The fine powder is then sealed and stored to obtain a bio-based intumescent flame retardant component powder.

[0044] Optionally, the preparation of sodium alginate solution and ferric chloride crosslinking solution based on sodium alginate and deionized water includes:

[0045] Sodium alginate and deionized water were stirred evenly until sodium alginate was completely dissolved to obtain sodium alginate solution.

[0046] Determine the ferric chloride hexahydrate, the target concentration, and the volume of the ferric chloride solution. Calculate the total molar mass of ferric chloride hexahydrate based on the total molar mass, the target concentration, and the volume of the ferric chloride solution. Calculate the required mass of ferric chloride hexahydrate based on the total molar mass, the target concentration, and the volume of the ferric chloride solution.

[0047] Weigh the required amount of ferric chloride hexahydrate crystals according to the required mass, and perform preliminary dissolution of the required ferric chloride hexahydrate crystals and deionized water to obtain a preliminary solution;

[0048] The initially dissolved solution is quantitatively transferred to the volumetric flask to obtain the solution to be determined to volume, wherein the volumetric flask contains volumetric graduation lines;

[0049] Obtain the liquid level of the solution to be diluted in the volumetric flask, and determine whether the liquid level is equal to the graduation mark of the volumetric flask.

[0050] If the liquid level is not equal to the graduation mark on the volumetric flask, then dilute the solution to volume until the liquid level is equal to the graduation mark on the volumetric flask to obtain a diluted solution. Shake the diluted solution thoroughly to obtain a ferric chloride crosslinked solution.

[0051] Optionally, the preparation of gel particle aggregates based on sodium alginate solution and ferric chloride crosslinking solution includes:

[0052] Sodium alginate solution was added to ferric chloride crosslinking solution to obtain a crosslinking mixture. The crosslinking mixture was sealed to obtain a sealed mixture. The sealed mixture was then subjected to a aging process to obtain a aging mixture.

[0053] The matured mixture was filtered to obtain a set of filtered gel particles. The filtered gel particles were washed to obtain an initial set of gel particles and filtrate. The acidity and alkalinity of the filtrate were tested to obtain the initial pH value.

[0054] If the initial pH value is not equal to the preset neutral pH value, then the initial gel particle set is taken as the gel particle set, and the process returns to the step of washing the filtered gel particle set until the initial pH value is equal to the neutral pH value.

[0055] If the initial pH value is equal to the neutral pH value, then the initial set of gel particles is taken as the gel particle set.

[0056] Optionally, the preparation of the insulating flame-retardant fire extinguishing agent based on the bio-based intumescent flame-retardant component powder and the catalytic char-forming synergistic component powder includes:

[0057] The total mass of the extinguishing agent dry powder and the optimal synergistic ratio were determined. Based on the optimal synergistic ratio, the required mass of flame-retardant component powder and the required mass of char synergistic component powder were calculated.

[0058] Based on the required mass of flame retardant component powder and the required mass of char synergistic component powder, weigh the required flame retardant component powder and the required char synergistic component powder respectively from the bio-based intumescent flame retardant component powder and the catalytic char synergistic component powder.

[0059] The required flame retardant component powders are grouped to obtain a set of flame retardant powders of the same mass. Flame retardant powders of the same mass are extracted from the set of flame retardant powders of the same mass. The flame retardant powders of the same mass are removed from the set of flame retardant powders of the same mass to obtain an updated set of flame retardant powders of the same mass.

[0060] The extracted flame retardant powder of the same mass is poured into a pre-constructed mixing tank to obtain a feeding mixing tank. The required carbon synergistic component powder is poured into the feeding mixing tank to obtain an initial mixture. The initial mixture is then covered with an updated set of flame retardant powder of the same mass to obtain the mixture to be mixed.

[0061] The materials to be mixed are mixed using a preset mixing time to obtain dry powder of insulating flame retardant fire extinguishing agent. The dry powder of insulating flame retardant fire extinguishing agent is then sealed and stored to obtain insulating flame retardant fire extinguishing agent.

[0062] To achieve the above objectives, the present invention also provides an insulating flame-retardant fire extinguishing agent and its preparation system, comprising:

[0063] The fire extinguishing agent material confirmation module is used to receive the preparation instructions for the insulating flame-retardant fire extinguishing agent, and confirm the preparation materials and preparation device according to the preparation instructions. The preparation materials include: ethanol solution, diluent, curing agent of the same mass, sodium alginate and deionized water. The preparation device includes: multiple empty beakers, sample mold set, three-necked flask and volumetric flask.

[0064] The flame retardant component powder preparation module is used to obtain the optimal mass ratio, and weigh out ammonium polyphosphate powder, pentaerythritol powder and lignin powder according to the optimal mass ratio.

[0065] The synergistic powder preparation module is used to prepare bio-based intumescent flame retardant component powder based on ammonium polyphosphate powder, pentaerythritol powder and lignin powder, prepare sodium alginate solution and ferric chloride crosslinking solution based on sodium alginate and deionized water, prepare gel particle set based on sodium alginate solution and ferric chloride crosslinking solution, and obtain catalytic char formation synergistic component powder based on gel particle set.

[0066] The fire extinguishing agent preparation module is used to prepare an insulating flame-retardant fire extinguishing agent based on bio-based intumescent flame-retardant component powder and catalytic char-forming synergistic component powder, and to complete the preparation of the insulating flame-retardant fire extinguishing agent based on the insulating flame-retardant fire extinguishing agent.

[0067] To address the above problems, the present invention also provides an electronic device, the electronic device comprising:

[0068] Memory, storing at least one instruction;

[0069] The processor executes the instructions stored in the memory to implement the above-described insulating flame-retardant fire extinguishing agent and its preparation method.

[0070] To address the aforementioned problems, the present invention also provides a computer-readable storage medium storing at least one instruction, which is executed by a processor in an electronic device to implement the aforementioned insulating flame-retardant fire extinguishing agent and its preparation method.

[0071] To address the problems described in the background art, this invention receives a preparation instruction for an insulating flame-retardant fire extinguishing agent and identifies the preparation materials and apparatus based on this instruction. The preparation materials include: an ethanol solution, a diluent, an equal mass of a curing agent, sodium alginate, and deionized water. The preparation apparatus includes: multiple empty beakers, a sample mold set, a three-necked flask, and a volumetric flask. This invention confirms the preparation materials, ensuring the completeness of all necessary substances for subsequent preparation, providing a material basis for preparing a compliant insulating flame-retardant fire extinguishing agent. Different materials play different roles in the fire extinguishing agent; obtaining the optimal mass ratio involves weighing ammonium polyphosphate powder, pentaerythritol powder, and lignin powder according to the optimal mass ratio. This optimal mass ratio allows these three substances to exert the best synergistic effect in subsequent reactions, thereby improving the flame-retardant performance of the bio-based intumescent flame-retardant component. The bio-based intumescent flame-retardant component powder is prepared based on ammonium polyphosphate powder, pentaerythritol powder, and lignin powder. Sodium alginate solution and ferric chloride crosslinking solution are prepared based on sodium alginate and deionized water. This invention prepares a bio-based intumescent flame-retardant component powder, utilizing the properties of ammonium polyphosphate, pentaerythritol, and lignin. During a fire, this component expands upon heating to form a heat-insulating layer, preventing the transfer of heat and oxygen, thus achieving a flame-retardant effect. Furthermore, the use of bio-based materials (such as lignin) offers advantages such as environmental friendliness and renewability. Gel particle aggregates are prepared based on sodium alginate solution and ferric chloride crosslinking solution. Catalytic char-forming synergistic component powder is obtained from the gel particle aggregates. The preparation of sodium alginate solution and ferric chloride crosslinking solution lays the foundation for the subsequent preparation of gel particle aggregates. An insulating flame-retardant fire extinguishing agent is prepared based on the bio-based intumescent flame-retardant component powder and the catalytic char-forming synergistic component powder. The insulating flame-retardant fire extinguishing agent is then prepared based on this agent. This invention combines bio-based intumescent flame-retardant component powder and catalytic char-forming synergistic component powder to prepare an insulating flame-retardant fire extinguishing agent, enabling the fire extinguishing agent to simultaneously possess the functions of intumescent flame retardancy and catalytic char formation. It can effectively prevent combustion in a fire and may also have good insulation properties, making it suitable for special scenarios such as electrical fires. Therefore, this invention can achieve stable quality of fire extinguishing agents and safe and environmentally friendly production. Attached Figure Description

[0080] Reference Figure 1 The diagram shown is a schematic flow chart of an insulating flame-retardant fire extinguishing agent and its preparation method according to an embodiment of the present invention. In this embodiment, the insulating flame-retardant fire extinguishing agent and its preparation method include:

[0081] S1. Receive the instruction to prepare the insulating flame-retardant fire extinguishing agent, and confirm the preparation materials and preparation device according to the instruction.

[0082] Specifically, the preparation materials include: ethanol solution, diluent, curing agent of the same mass, sodium alginate and deionized water, and the preparation apparatus includes: multiple empty beakers, a sample mold set, a three-necked flask and a volumetric flask.

[0083] It should be explained that the preparation instruction for the insulating flame-retardant extinguishing agent refers to the instruction issued by the operator for subsequent batching and process execution. Ethanol solution refers to anhydrous ethanol, used as a dispersion medium or solvent.

[0084] S2. Obtain the optimal mass ratio by weighing ammonium polyphosphate powder, pentaerythritol powder, and lignin powder according to the optimal mass ratio.

[0085] Specifically, obtaining the optimal quality ratio includes:

[0086] Obtain epoxy resin of the same mass and add it into multiple empty beakers to obtain multiple beakers to be preheated.

[0087] Each of the multiple beakers to be preheated was preheated in a water bath using a preset preheating time, resulting in multiple preheated beakers.

[0088] Set an initial experimental ratio set, extract the initial experimental ratios sequentially from the initial experimental ratio set, and obtain the formulation intumescent flame retardant based on the extracted initial experimental ratios;

[0089] Randomly select a target preheated beaker from multiple preheated beakers, add the formulation of intumescent flame retardant into the target preheated beaker, and obtain the mixture to be stirred.

[0090] The mixture to be stirred is initially stirred to obtain a viscous paste mixture. The viscous paste mixture is then diluted with a diluent to obtain a diluted mixture. The diluted mixture is then stirred at high speed to obtain the material to be ground.

[0091] Based on the material to be ground, a set of performance test values ​​is obtained, and the set of performance test values ​​is summarized to obtain a set of performance test values ​​corresponding to the initial experimental ratio set. The initial experimental ratio and the set of performance test values ​​correspond one-to-one.

[0092] Extract performance test value groups sequentially from the performance test value group set, calculate the comprehensive performance test value based on the extracted performance test value groups, and summarize the comprehensive performance test values ​​to obtain the comprehensive performance test value set;

[0093] The maximum comprehensive performance test value is determined based on the comprehensive performance test value set, and the initial experimental ratio corresponding to the maximum comprehensive performance test value is taken as the optimal mass ratio.

[0094] It should be explained that "epoxy resin of equal mass" refers to a collection composed of epoxy resins of the same mass. "Epoxy resin of equal mass" means epoxy resins with the same mass. "Empty beaker" refers to a clean, dry, and numbered glass beaker used to hold epoxy resin of the same mass. "Beaker to be preheated" refers to the beaker obtained after pouring epoxy resin of the same mass into the empty beaker, ready for water bath preheating. "Preheating time" refers to the pre-set constant temperature water bath time. Water bath preheating of each of the multiple beakers to be preheated aims to reduce the viscosity of the epoxy resin, facilitating rapid dispersion and wetting of the subsequent flame retardant and reducing agglomeration. "Preheated beaker" refers to the beaker after completing the specified preheating time. "Initial experimental ratio set" refers to the set of pre-set mass ratios between ammonium polyphosphate, pentaerythritol, and lignin. "Formulated intumescent flame retardant" refers to the composition weighed and mixed according to the currently extracted initial experimental ratio. The target preheated beaker refers to a beaker randomly selected from multiple preheated beakers to hold the current formulation of intumescent flame retardant. The mixture to be stirred refers to the mixture obtained after pouring the formulation of intumescent flame retardant into the target preheated beaker in one go. A viscous paste mixture refers to a homogeneous but high-viscosity paste formed after stirring with a glass rod. A diluent is a solution used to reduce the viscosity of the system, generating sufficient shear force during high-speed stirring to break up powder agglomerates and achieve nanoscale dispersion. For example, anhydrous ethanol is a diluent. A diluted mixture refers to a low-viscosity fluid after adding a diluent and stirring. The material to be ground refers to a homogeneous slurry obtained after high-speed stirring (e.g., 1000–2000 rpm, 5–10 min). A performance test value set refers to a collection of performance test value groups. A comprehensive performance test value set refers to a collection of comprehensive performance test values. The maximum comprehensive performance test value refers to the highest comprehensive performance test value.

[0095] Specifically, the set of performance test values ​​obtained based on the material to be ground includes:

[0096] The material to be ground is subjected to multiple grinding operations to obtain ground material. The same mass of curing agent is then added to the ground material to obtain cured ground material.

[0097] The solidified grinding material is stirred to obtain a stirred mixture. The stirred mixture is then subjected to a vacuum degassing operation to obtain a degassed material.

[0098] A deaerated material sample set is extracted from the deaerated material, and a casting template mold set is obtained based on the deaerated material sample set and the template mold set. The template mold set includes: oxygen index spline mold, vertical combustion spline mold and cone calorimeter template mold.

[0099] The casting sample molds are extracted sequentially from the set of casting sample molds, and a curing operation is performed on the extracted casting sample molds to obtain the cured sample molds. The state of the cured sample molds is adjusted to obtain the composite material sample to be tested.

[0100] The composite material samples to be tested are compiled to obtain a sample set of composite materials to be tested, which includes: flame retardant performance test samples, mechanical performance test samples and thermal stability test samples;

[0101] The performance of the composite material sample set to be tested was carried out to obtain the performance test value set.

[0102] It should be explained that performing multiple grinding operations on the material to be ground refers to using a three-roll mill to grind the material multiple times until the fineness of the material is less than the preset fineness (e.g., 20 micrometers). The ground material refers to the fine slurry obtained after multiple grinding operations. The purpose of performing multiple grinding operations is to thoroughly break up agglomerates and achieve uniform nano / micron-level dispersion of the flame retardant in the resin. Equal mass curing agent refers to a curing agent of the same mass. For example, equal mass curing agent is a polyamide curing agent. Cured ground material refers to the material obtained after adding the same mass of curing agent. The stirred mixture refers to the cured ground material after stirring. Performing vacuum degassing on the stirred mixture refers to performing vacuum degassing on the stirred mixture using a vacuum degassing tank. A vacuum degassing tank is a sealed stainless steel tank equipped with a vacuum gauge, stirring paddle, and heating jacket, used to remove air trapped in the slurry, preventing bubbles and pinholes from appearing in the cured ground material, affecting mechanical and flame retardant testing. Vacuum degassing is existing technology and will not be elaborated further here. Deaerated material refers to a slurry with no bubbles and a smooth, mirror-like surface obtained after vacuum deaeration. A deaerated material sample set is a collection of deaerated material samples. It should be noted that each deaerated material sample in the sample set has the same mass. A casting template mold set refers to a collection of casting template molds. Oxygen index spline molds, vertical combustion spline molds, and cone calorimeter template molds refer to molds used for flame retardant performance testing, molds used for testing the vertical flame retardant performance of plastic materials, and molds used to produce molds of specified dimensions, respectively. The curing operation refers to smoothly transferring all the cast molds into a 60±2℃ forced-air drying oven, closing the oven door, and curing at a constant temperature of 60℃ for 72 hours. A cured template mold refers to a mold after curing. Conditioning refers to the storage operation under standard temperature and humidity conditions. A composite material sample to be tested refers to a sample after the cured template mold has naturally cooled and been demolded. The step of obtaining the casting template mold set based on the deaerated material sample set and the template mold set is as follows: Deaerated material samples from the deaerated material sample set are poured onto template molds from the template mold set to obtain the casting template mold set, with each deaerated material sample corresponding to a template mold. The flame retardant performance test template is used to determine the limiting oxygen index, UL-94 rating, and heat release rate. The mechanical property test template is used to determine tensile strength, flexural strength, and impact toughness. The thermal stability test template is used in a thermogravimetric analyzer to...10℃ min-1 The sample was used to determine the temperature at which the mass loss was 5% and the temperature at which the maximum weight loss rate was reached.

[0103] Specifically, the performance testing of the composite material sample set to be tested, to obtain a set of performance test values, includes:

[0104] Flame retardant performance testing was performed on the flame retardant performance test samples of the composite material sample set to be tested, and the limiting oxygen index, vertical burning rating, peak heat release rate and total heat release were obtained.

[0105] Mechanical property testing was performed on the mechanical property test specimen to obtain tensile strength and flexural strength; thermal stability testing was performed on the thermal stability test specimen to obtain residual carbon rate.

[0106] Performance test value groups were determined based on limiting oxygen index, vertical combustion rating, peak heat release rate, total heat release, tensile strength, flexural strength, and residual carbon content.

[0107] It should be explained that the flame retardant performance testing operation refers to the entire process of placing the flame retardant performance test sample sequentially into an oxygen index meter, a vertical combustion chamber, and a cone calorimeter, igniting the flame retardant performance test sample according to a standard procedure, and recording the combustion behavior and heat release data of the flame retardant performance test sample. The limiting oxygen index (LOI) is the minimum oxygen volume fraction required to sustain the flame retardant performance test sample in an oxygen-nitrogen mixed gas flow for a preset time (e.g., 3 minutes). The higher the LIO, the more difficult the material is to ignite. There are four vertical combustion ratings, which are existing technologies and will not be elaborated upon here. The peak heat release rate is the maximum heat release rate per unit area recorded by the cone calorimeter under thermal irradiation. The lower the peak heat release rate, the less flame propagation and heat impact, and the lower the fire hazard. The total heat release is the cumulative value of the heat released by the composite material sample under test from ignition to flame extinguishing. The mechanical property testing operation refers to the operation of performing tensile and bending tests using a universal testing machine. Tensile strength refers to the maximum stress at which axial tension reaches fracture. A high tensile strength retention rate indicates that flame-retardant modification causes minimal damage to the toughness of the resin matrix. Flexural strength refers to the maximum bending stress of the outer fibers of the composite material sample before fracture. Thermal stability testing refers to the thermogravimetric analysis performed on the sample. Carbon residue refers to the percentage of non-volatile solid matter remaining relative to the initial sample mass after heating the composite material sample from room temperature to a very high target temperature (e.g., 700°C) at a constant rate in an inert gas atmosphere (such as nitrogen or helium).

[0108] Specifically, the calculation of the comprehensive performance test value based on the extracted performance test value set includes:

[0109] Based on the set of performance test values, the maximum extreme oxygen index, minimum peak heat release rate, minimum total heat release, maximum tensile strength, maximum flexural strength, and maximum char rate were determined.

[0110] The target limiting oxygen index, target vertical combustion rating, target peak heat release rate, target total heat release, target tensile strength, target flexural strength, and target char rate were confirmed from the extracted performance test value set.

[0111] The flame retardant performance score is calculated based on the measured value of the target limiting oxygen index, the maximum limiting oxygen index value, the target vertical burning rating, the target peak heat release rate, the target total heat release, the minimum peak heat release rate, and the minimum total heat release.

[0112] The mechanical property score is calculated based on the target tensile strength, target bending strength, maximum tensile strength, and maximum bending strength.

[0113] The thermal stability score is calculated based on the maximum char rate and the target char rate. The flame retardant performance score, mechanical performance score and thermal stability score are weighted and summed to obtain the comprehensive performance test value.

[0114] It should be explained that the maximum limiting oxygen index (VOI), maximum tensile strength, maximum flexural strength, and maximum char rate refer to the highest VOI, maximum tensile strength, maximum flexural strength, and maximum char rate in the performance test value set, respectively. The minimum peak heat release rate and minimum total heat release refer to the minimum peak heat release rate and minimum total heat release in the performance test value set, respectively. The target limiting oxygen index (VOI) measured value, target vertical flammability rating, target peak heat release rate, target total heat release, target tensile strength, target flexural strength, and target char rate refer to the corresponding VOI measured value, vertical flammability rating, peak heat release rate, total heat release, tensile strength, flexural strength, and char rate for the extracted performance test value set, respectively. The formula for calculating the flame retardant performance score in the step of calculating the flame retardant performance score based on the target limiting oxygen index measured value, target vertical flammability rating, target peak heat release rate, target total heat release, minimum peak heat release rate, and minimum total heat release is shown below:

[0115]

[0116] in, The score indicates the flame retardant performance. This represents the measured value of the target limiting oxygen index. This represents the maximum oxygen index value. This indicates the preset limiting oxygen index weight. Indicates the target vertical combustion rating. This indicates the preset grade score weights. Indicates the target peak heat release rate. Indicates the minimum peak heat release rate. This indicates the preset overall weight. This represents the target total heat release. This represents the minimum total heat release.

[0117] It should be noted that the limiting oxygen index (LOI) weight, grade score weight, and overall weight are all preset values. In the flame retardant performance evaluation system, the weight allocation of the LIO and vertical burning rating is determined based on their influence on the flame retardant safety of the material. The LIO, by measuring the minimum oxygen concentration required for sustained combustion of a material, provides the most basic fire safety threshold for the material. The vertical burning rating comprehensively evaluates the material's self-extinguishing tendency, flame spread resistance, and dripping characteristics; its test results are directly related to the early fire development and risk control in actual fires. Therefore, the LIO and vertical burning rating together constitute the core basis for flame retardant performance evaluation and safety standard certification. Thus, when calculating the flame retardant performance score, their contributions must be significantly enhanced. Preferably, the LIO weight and grade score weight are both set to 40%. Cone calorimetry, by simulating actual fire source conditions under controlled radiant heat flow, accurately records dynamic parameters such as the heat release rate, total heat release, and smoke generation rate during the material's combustion process. It can quantitatively characterize the power and energy release characteristics of the material in real fire scenarios, providing an irreplaceable data foundation for assessing fire hazards across all scales. Given that the conical calorimetry test is more complex than the basic flame retardant test in terms of equipment complexity and data analysis dimensions, it is given necessary correction and supplementary weights in calculating the flame retardant performance score. Preferably, the overall weight of the conical calorimetry test is set to 20%. The calculation formula for the mechanical performance score in the step of calculating the mechanical performance score based on the target tensile strength, target flexural strength, maximum tensile strength, and maximum flexural strength is as follows:

[0118]

[0119] in, Indicates the mechanical performance score. Indicates the target tensile strength. Indicates the maximum tensile strength. Indicates the target bending strength. This represents the maximum bending strength. The thermal stability score is the value obtained by dividing the target char rate by the maximum char rate. The weighted summation is the sum of the flame retardant performance score, mechanical performance score, and thermal stability score multiplied by their respective weights. These weights are pre-set values.

[0120] S3. Bio-based intumescent flame retardant component powders were prepared based on ammonium polyphosphate powder, pentaerythritol powder and lignin powder. Sodium alginate solution and ferric chloride crosslinking solution were prepared based on sodium alginate and deionized water.

[0121] Specifically, the preparation of bio-based intumescent flame-retardant component powder based on ammonium polyphosphate powder, pentaerythritol powder, and lignin powder includes:

[0122] Ethanol solution, ammonium polyphosphate powder, pentaerythritol powder and lignin powder were introduced into a three-necked flask to obtain the solution to be mixed.

[0123] Simultaneous stirring and heating are performed on the mixed solution to obtain the initial temperature and the initial mixed solution. When the initial temperature is within the preset sufficient reaction temperature range, the stirring time is obtained by taking the time when the initial temperature is within the preset sufficient reaction temperature range as the starting point and recording the time in real time.

[0124] When the stirring time is equal to the preset continuous stirring time, the stirring is stopped on the initial mixed solution to obtain the reaction mixed solution. The reaction mixed solution is then cooled to obtain the cooled mixed solution.

[0125] The cooled mixed solution was filtered to obtain the separated solid product;

[0126] The separated solid product is washed multiple times to obtain a purified solid product, which is then dried to obtain a dried solid product.

[0127] The dried solid product is ground to obtain an initial ground powder, which is then sieved to obtain a fine powder. The fine powder is then sealed and stored to obtain a bio-based intumescent flame retardant component powder.

[0128] It should be explained that the optimal mass ratio refers to the experimentally optimized mass ratio of ammonium polyphosphate powder, pentaerythritol powder, and lignin powder in the preparation of bio-based intumescent flame-retardant component powder. This ratio optimizes the flame-retardant properties (such as charring, expansion, and smoke suppression) while considering cost, environmental friendliness, and processing performance. Ammonium polyphosphate powder is a commonly used acid and gas source, playing a crucial role in the intumescent flame-retardant system. At high temperatures, it decomposes to produce acidic substances such as phosphoric acid and polyphosphoric acid, promoting the dehydration and carbonization of the charring agent. Simultaneously, it releases non-flammable gases such as ammonia and water vapor, diluting the oxygen concentration. It is a white powder with good water solubility, is environmentally friendly, and non-toxic. Pentaerythritol powder is a carbon source, a polyhydroxy compound. At high temperatures, it reacts with the acidic substances produced by the decomposition of ammonium polyphosphate, dehydrating to form a stable intumescent char layer that covers the material surface, isolating heat and oxygen. It is a white crystalline powder with good thermal stability. Lignin powder is a natural polymer, a brownish-red powder derived from plant cell walls, and belongs to renewable bio-based materials. In this invention, it serves as an auxiliary carbon source or synergistic flame retardant, not only providing a char source but also potentially enhancing the thermal stability of the char layer through its aromatic structure. Simultaneously, it improves the environmental friendliness and sustainability of the system.

[0129] Understandably, a three-necked flask is a glass reaction vessel with three openings. This step uses a three-necked flask to utilize its multi-port structure to simultaneously achieve three functions: mechanical stirring, reflux condensation, and temperature monitoring. Each function corresponds to one opening, ensuring that the reactants complete the synthesis reaction uniformly, fully, and safely in the ethanol solution. The solution to be mixed refers to the solution after adding the ethanol solution, ammonium polyphosphate powder, pentaerythritol powder, and lignin powder to the three-necked flask in the optimal mass ratio, before heating and stirring have begun. Simultaneous stirring and heating refers to the operation of mechanical stirring during heating. This operation aims to prevent localized overheating or agglomeration, while simultaneously accelerating mass and heat transfer and increasing the reaction rate. The initial temperature refers to the temperature reached after simultaneous stirring and heating of the mixed solution begins. It is used to determine whether the sufficient reaction temperature range has been entered and serves as the starting point for subsequent timing and reaction control. The initial mixed solution refers to the mixed solution when the system temperature reaches the initial temperature after the simultaneous stirring and heating operation begins. The sufficient reaction temperature range refers to the pre-set temperature range that allows the components to react effectively and synergistically (such as forming a stable flame-retardant composite structure and promoting interfacial bonding). The stirring time refers to the duration from the moment the initial temperature reaches the optimal reaction temperature range until the continuous stirring time, used to ensure a complete but not excessive reaction. The continuous stirring time refers to the pre-set optimal reaction time. For example, the continuous stirring time is 4 hours. The reaction mixture refers to the mixture obtained after continuous stirring has ended. The filtration of the cooled mixture refers to using a filtration device and a vacuum pump to filter the cooled mixture.

[0130] Importantly, cooling the reaction mixture refers to naturally cooling the reaction mixture to room temperature (e.g., 25°C). A cooled mixture refers to the solution after naturally cooling the reaction mixture to room temperature. The filtration device is a filtration system consisting of a Buchner funnel, a filtration flask, and filter paper, used for solid-liquid separation. Under the action of a vacuum pump, the solid product is rapidly separated from the ethanol solution. The vacuum pump, used in conjunction with the filtration device, provides a negative pressure environment, accelerates the filtration process, and improves separation efficiency. The separated solid product refers to the solid mixture separated from the cooled mixture by filtration. This solid mixture may have residual ethanol or small amounts of soluble impurities on its surface, therefore, a subsequent washing step is required. Performing multiple washing operations on the separated solid product refers to washing the separated solid product multiple times with anhydrous ethanol. The purified solid product refers to the solid product after multiple washings to remove residual solvent, free ions, or unreacted small molecules. Drying the purified solid product refers to drying the purified solid product using a constant-temperature forced-air drying oven. The dried solid product refers to the product obtained by drying a purified solid product to constant weight in a forced-air drying oven. It should be noted that the drying temperature is 80℃ to avoid component decomposition due to high temperature. Grinding the dried solid product refers to grinding it using a ball mill. Initially ground powder refers to the powder obtained after preliminary grinding of the dried solid product using a ball mill. Sieving the initial ground powder refers to sieving the initial ground powder using a sieve. For example, a 200-mesh sieve. Fine powder refers to powder with uniform and fine particle size obtained after sieving. The purpose of the sealed storage described in this invention is to prevent the fine powder from absorbing moisture and clumping or migrating components. The bio-based intumescent flame-retardant component powder is a functional flame-retardant additive composed of ammonium polyphosphate, pentaerythritol, and lignin in an optimal mass ratio.

[0131] Specifically, the preparation of sodium alginate solution and ferric chloride crosslinking solution based on sodium alginate and deionized water includes:

[0132] Sodium alginate and deionized water were stirred evenly until sodium alginate was completely dissolved to obtain sodium alginate solution.

[0133] Determine the ferric chloride hexahydrate, the target concentration, and the volume of the ferric chloride solution. Calculate the total molar mass of ferric chloride hexahydrate based on the total molar mass, the target concentration, and the volume of the ferric chloride solution. Calculate the required mass of ferric chloride hexahydrate based on the total molar mass, the target concentration, and the volume of the ferric chloride solution.

[0134] Weigh the required amount of ferric chloride hexahydrate crystals according to the required mass, and perform preliminary dissolution of the required ferric chloride hexahydrate crystals and deionized water to obtain a preliminary solution;

[0135] The initially dissolved solution is quantitatively transferred to the volumetric flask to obtain the solution to be determined to volume, wherein the volumetric flask contains volumetric graduation lines;

[0136] Obtain the liquid level of the solution to be diluted in the volumetric flask, and determine whether the liquid level is equal to the graduation mark of the volumetric flask.

[0137] If the liquid level is not equal to the graduation mark on the volumetric flask, then dilute the solution to volume until the liquid level is equal to the graduation mark on the volumetric flask to obtain a diluted solution. Shake the diluted solution thoroughly to obtain a ferric chloride crosslinked solution.

[0138] It should be explained that sodium alginate is a natural polysaccharide extracted from brown algae, which can react with... under mild conditions. Fe3+ An ionic cross-linking network is formed instantly. Deionized water can prevent premature cross-linking of impurities or the introduction of byproducts, ensuring gel purity. The step of uniformly stirring sodium alginate and deionized water is as follows: while stirring the deionized water, sodium alginate is evenly sprinkled into the stirring deionized water to prevent clumping. Sodium alginate solution refers to a light brown viscous liquid obtained by uniformly stirring sodium alginate and deionized water. Target concentration refers to a pre-set concentration. FeCl3The final molar concentration. The volume of the ferric chloride solution refers to the final volume of solution to be prepared. The total molar mass refers to the amount of substance of ferric chloride hexahydrate. The required mass of ferric chloride hexahydrate is the product of the total molar mass, the target concentration, and the volume of the ferric chloride solution. The required mass of ferric chloride hexahydrate crystals refers to the precisely weighed mass of ferric chloride hexahydrate. It should be noted that the required ferric chloride hexahydrate crystals should be dissolved immediately after weighing to avoid moisture absorption and weight gain, which would lead to a lower concentration. Preliminary dissolution refers to adding the required ferric chloride hexahydrate crystals to deionized water in batches, while continuously stirring with a glass rod until all solids are completely dissolved. The preliminary dissolved solution is the solution obtained after all solids have completely dissolved in deionized water. Quantitatively transferring the preliminary dissolved solution to a pre-constructed volumetric flask means transferring the entire preliminary dissolved solution into a volumetric flask without loss using a glass rod. The solution to be diluted to volume refers to the solution where the preliminary dissolved solution has been completely transferred into the volumetric flask, but the liquid level has not yet reached the graduation mark. The liquid level height refers to the vertical position of the lowest point of the meniscus relative to the graduation mark of the volumetric flask. The process of adjusting the volume of the solution to be adjusted refers to using a dropper to take an appropriate amount of deionized water from the deionized water and adjust the volume accordingly. The dropper is a special glass dropper used for volume adjustment, added drop by drop near the graduation mark to avoid adding too much at once and causing volume loss. Each drop is approximately 0.05 mL. The solution to be adjusted refers to the solution whose liquid level is accurately reached to the graduation mark on the volumetric flask. Thorough shaking involves tightening the stopper of the volumetric flask, inverting it until it is upright (this counts as one shake), and repeating this 10–15 times to ensure that the concentration of the solution is completely consistent both vertically and horizontally, preventing localized concentration differences due to insufficient diffusion. The ferric chloride crosslinked solution refers to the brownish-yellow transparent solution obtained after volume adjustment and shaking. Fe3+ With a known concentration, it can be directly mixed with sodium alginate solution to form an ionic cross-linked gel, thereby preparing a catalytic carbonization synergistic component powder.

[0139] S4. Gel particle sets are prepared based on sodium alginate solution and ferric chloride crosslinking solution, and catalytic carbonization synergistic component powder is obtained from the gel particle sets.

[0140] Specifically, the preparation of gel particle aggregates based on sodium alginate solution and ferric chloride crosslinking solution includes:

[0141] Sodium alginate solution was added to ferric chloride crosslinking solution to obtain a crosslinking mixture. The crosslinking mixture was sealed to obtain a sealed mixture. The sealed mixture was then subjected to a aging process to obtain a aging mixture.

[0142] The matured mixture was filtered to obtain a set of filtered gel particles. The filtered gel particles were washed to obtain an initial set of gel particles and filtrate. The acidity and alkalinity of the filtrate were tested to obtain the initial pH value.

[0143] If the initial pH value is not equal to the preset neutral pH value, then the initial gel particle set is taken as the gel particle set, and the process returns to the step of washing the filtered gel particle set until the initial pH value is equal to the neutral pH value.

[0144] If the initial pH value is equal to the neutral pH value, then the initial set of gel particles is taken as the gel particle set.

[0145] It should be explained that adding sodium alginate solution to the ferric chloride crosslinking solution refers to adding sodium alginate solution dropwise using a syringe under conditions of room temperature and gentle stirring (approximately 200-300 rpm). The crosslinking mixture refers to the mixture formed after adding sodium alginate solution dropwise or slowly to the ferric chloride crosslinking solution. Sealing the crosslinking mixture refers to sealing the crosslinking mixture with plastic wrap. Performing a maturation process on the sealed mixture refers to allowing the sealed mixture to stand at room temperature for more than 24 hours, the purpose of which is to allow… Fe3+ Ions have ample time to diffuse into the gel particles, ensuring complete and thorough cross-linking, thereby achieving stable mechanical properties. The matured mixture refers to the gel-liquid coexistence system after maturation, appearing as brownish-yellow gel particles uniformly dispersed in a colorless or light brown supernatant. The particle size has slightly shrunk compared to the initial cross-linking stage, resulting in a denser network, and it can be directly introduced into the solid-liquid separation process. The method for filtration of the matured mixture is the same as the method for filtration of the cooled mixed solution using a pre-constructed filtration device and a pre-constructed vacuum pump, and will not be repeated here. The filtration gel particle set refers to the collection of filtration gel particles remaining on the funnel after the filtration operation, at which point a large amount of filtration gel particles are still adsorbed on their surface. Fe3+ , Cl- And acidic solutions require further washing. The method for washing the vacuum-filtered gel particles is the same as the method for performing multiple washing operations on the separated solid products, and will not be described again here.

[0146] Importantly, the initial gel particle set refers to the set of vacuum-filtered gel particles after washing, where the pH of the filtrate is not yet equal to neutral pH. The filtrate refers to the liquid that passes through the funnel into the filtration flask during each vacuum filtration, containing free... Fe3+ , Cl- and a small amount H+The amount of residual acid and alkali on the gel surface can be indirectly determined by detecting its pH. The initial pH value refers to the measured pH value of the filtrate obtained after washing, reflecting the amount of residual acid on the initial gel particle surface. The neutral pH value refers to the pre-set pH value. For example, the neutral pH value is 7. When the initial pH value of the filtrate is equal to the neutral pH value, it indicates that there is basically no free acid on the gel surface, and washing can be terminated. The purpose of this step is to avoid residual acid affecting subsequent drying and flame retardant properties. The gel particle set refers to the initial gel particle set with an initial pH value equal to the neutral pH value. The method for obtaining the catalytic char-forming synergistic component powder based on the gel particle set is the same as the method for obtaining the bio-based intumescent flame retardant component powder based on the purified solid product, and will not be repeated here. The catalytic char-forming synergistic component powder refers to the fine powder obtained after drying and grinding. This powder can, during the polymer combustion process, pass through the catalytic char-forming synergistic component powder contained therein. Fe3+ Catalysis forms a dense and highly graphitized carbon layer. This carbon layer acts as a physical barrier, achieving a synergistic effect of smoke suppression, heat insulation, and flame retardancy.

[0147] S5. Prepare an insulating flame-retardant fire extinguishing agent based on bio-based intumescent flame-retardant component powder and catalytic char-forming synergistic component powder, and complete the preparation of the insulating flame-retardant fire extinguishing agent based on the insulating flame-retardant fire extinguishing agent.

[0148] In detail, the preparation of the insulating flame-retardant fire extinguishing agent based on the bio-based intumescent flame-retardant component powder and the catalytic char-forming synergistic component powder includes:

[0149] The total mass of the extinguishing agent dry powder and the optimal synergistic ratio were determined. Based on the optimal synergistic ratio, the required mass of flame-retardant component powder and the required mass of char synergistic component powder were calculated.

[0150] Based on the required mass of flame retardant component powder and the required mass of char synergistic component powder, weigh the required flame retardant component powder and the required char synergistic component powder respectively from the bio-based intumescent flame retardant component powder and the catalytic char synergistic component powder.

[0151] The required flame retardant component powders are grouped to obtain a set of flame retardant powders of the same mass. Flame retardant powders of the same mass are extracted from the set of flame retardant powders of the same mass. The flame retardant powders of the same mass are removed from the set of flame retardant powders of the same mass to obtain an updated set of flame retardant powders of the same mass.

[0152] The extracted flame retardant powder of the same mass is poured into a pre-constructed mixing tank to obtain a feeding mixing tank. The required carbon synergistic component powder is poured into the feeding mixing tank to obtain an initial mixture. The initial mixture is then covered with an updated set of flame retardant powder of the same mass to obtain the mixture to be mixed.

[0153] The materials to be mixed are mixed using a preset mixing time to obtain dry powder of insulating flame retardant fire extinguishing agent. The dry powder of insulating flame retardant fire extinguishing agent is then sealed and stored to obtain insulating flame retardant fire extinguishing agent.

[0154] It should be explained that the total mass of the extinguishing agent dry powder refers to the total dry weight of the final product of the prepared insulating flame-retardant extinguishing agent. The optimal synergistic ratio refers to the pre-set ratio where the expanded char layer and the catalytic graphitization effect synergize best, resulting in the shortest extinguishing time and no reignition. The required mass of the flame-retardant component powder is the value obtained by multiplying the total mass of the extinguishing agent dry powder by the proportion of flame retardant in the optimal synergistic ratio. The required mass of the char synergistic component powder is the value obtained by multiplying the total mass of the extinguishing agent dry powder by the proportion of char synergistic effect in the optimal synergistic ratio. The required flame-retardant component powder and the required char synergistic component powder refer to the bio-based expanded flame-retardant component powder and the catalytic char synergistic component powder, respectively, weighed using a precision balance and stored in a sealed container. The set of flame-retardant powder of equal mass refers to the set of flame-retardant powders of equal mass after the required flame-retardant component powder has been divided into two equal portions. The updated set of flame-retardant powder of equal mass refers to the set of flame-retardant powders of equal mass remaining after the extracted set. The mixing tank refers to a stainless steel tank with a sealed lid and a stirring paddle, used for dry mixing.

[0155] Understandably, the feeding mixing hopper refers to the mixing hopper after the first batch of flame retardant powder of the same mass has been added to the empty mixing hopper. The initial mixture refers to the mixture obtained after adding all the required char synergistic component powder to the feeding mixing hopper. Covering refers to the operation of evenly spreading the remaining flame retardant powder on top of the char synergistic component. The feeding method described above in this invention helps with initial dispersion and prevents the lighter required char synergistic component powder from generating dust or agglomerating during startup. The mixture to be mixed refers to the material prepared for formal mixing, which is completely covered with the remaining powder of the initial mixture using freshly collected flame retardant powder of the same mass, reducing the flying of light powder and electrostatic adsorption during high-speed stirring. The mixing time refers to the preset dry mixing time. The insulating flame retardant fire extinguishing agent dry powder refers to the final dry powder discharged after the set mixing time has been completed. The sealing and storage of the insulating flame retardant fire extinguishing agent dry powder refers to sealing and storing the insulating flame retardant fire extinguishing agent dry powder with plastic wrap to prevent moisture absorption and clumping. Insulating flame-retardant extinguishing agents refer to extinguishing agents that have the characteristics of fast fire extinguishing speed, no reignition, environmental friendliness, and the ability to extinguish electrical fires in an insulating manner.

[0156] Importantly, the present invention utilizes Fe3+ The synergistic effect between lignin and aromatic structures during combustion Fe3+This invention promotes the rapid formation of a dense char layer, while the lignin aromatic rings further enhance the thermal stability and continuity of the char layer. Therefore, while achieving the same or better flame-retardant effect, the total amount of flame retardant used in this invention is less than that required by traditional flame retardants, achieving highly efficient flame retardancy. Simultaneously, the hydrogen bonding in the system effectively improves the dispersibility of the flame-retardant components in the matrix, overcoming the problems of easy agglomeration and poor compatibility of single flame retardants. This design, while ensuring flame-retardant performance, reduces the negative impact on the mechanical properties of the material by controlling the amount of lignin used, and conforms to the concepts of green environmental protection and resource recycling. It should be noted that the embodiments of the present invention also provide an insulating flame-retardant fire extinguishing agent, comprising: 95% bio-based intumescent flame-retardant component powder, 5% catalytic char-forming synergistic component powder, and auxiliary materials. The bio-based intumescent flame-retardant component powder comprises: 54.29% ammonium polyphosphate, 27.14% pentaerythritol, and 13.57% lignin. The catalytic char-forming synergistic component powder comprises: 5% ferric alginate, wherein the ferric alginate comprises: 3.93% sodium alginate and 1.08% ferric chloride. The auxiliary material is a 50% aqueous ethanol solution.

[0157] To address the problems described in the background art, this invention receives a preparation instruction for an insulating flame-retardant fire extinguishing agent and identifies the preparation materials and apparatus based on this instruction. The preparation materials include: an ethanol solution, a diluent, an equal mass of a curing agent, sodium alginate, and deionized water. The preparation apparatus includes: multiple empty beakers, a sample mold set, a three-necked flask, and a volumetric flask. This invention confirms the preparation materials, ensuring the completeness of all necessary substances for subsequent preparation, providing a material basis for preparing a compliant insulating flame-retardant fire extinguishing agent. Different materials play different roles in the fire extinguishing agent; obtaining the optimal mass ratio involves weighing ammonium polyphosphate powder, pentaerythritol powder, and lignin powder according to the optimal mass ratio. This optimal mass ratio allows these three substances to exert the best synergistic effect in subsequent reactions, thereby improving the flame-retardant performance of the bio-based intumescent flame-retardant component. The bio-based intumescent flame-retardant component powder is prepared based on ammonium polyphosphate powder, pentaerythritol powder, and lignin powder. Sodium alginate solution and ferric chloride crosslinking solution are prepared based on sodium alginate and deionized water. This invention prepares a bio-based intumescent flame-retardant component powder, utilizing the properties of ammonium polyphosphate, pentaerythritol, and lignin. During a fire, this component expands upon heating to form a heat-insulating layer, preventing the transfer of heat and oxygen, thus achieving a flame-retardant effect. Furthermore, the use of bio-based materials (such as lignin) offers advantages such as environmental friendliness and renewability. Gel particle aggregates are prepared based on sodium alginate solution and ferric chloride crosslinking solution. Catalytic char-forming synergistic component powder is obtained from the gel particle aggregates. The preparation of sodium alginate solution and ferric chloride crosslinking solution lays the foundation for the subsequent preparation of gel particle aggregates. An insulating flame-retardant fire extinguishing agent is prepared based on the bio-based intumescent flame-retardant component powder and the catalytic char-forming synergistic component powder. The insulating flame-retardant fire extinguishing agent is then prepared based on this agent. This invention combines bio-based intumescent flame-retardant component powder and catalytic char-forming synergistic component powder to prepare an insulating flame-retardant fire extinguishing agent, enabling the fire extinguishing agent to simultaneously possess the functions of intumescent flame retardancy and catalytic char formation. It can effectively prevent combustion in a fire and may also have good insulation properties, making it suitable for special scenarios such as electrical fires. Therefore, this invention can achieve stable quality of fire extinguishing agents and safe and environmentally friendly production.
