Description

Technical Field

[0001] This invention relates to the field of fire protection technology, and in particular to a spore gel water-based fire extinguishing agent with ecological restoration function. Background Technology

[0002] In the field of fire protection, water-based fire extinguishing agents are widely used due to their high extinguishing efficiency and wide range of applications. However, existing water-based fire extinguishing agents have many shortcomings. Most fire extinguishing agents have a single function, only capable of extinguishing fires, and cannot restore the ecological environment at the fire scene after the fire, resulting in slow ecological recovery of the area after a fire.

[0003] In terms of flame retardant performance, traditional flame retardant systems often have unsatisfactory flame retardant effects and low flame retardant efficiency, making it difficult to form a stable and efficient flame retardant barrier. At the same time, existing fire extinguishing agents have insufficient adhesion to complex burning surfaces and are prone to detachment due to factors such as flame impact, failing to maintain fire extinguishing and protective effects for a long time.

[0004] Furthermore, some fire extinguishing agents use raw materials that may pollute the environment, failing to meet the requirements of sustainable development, and lack corresponding benefits in areas such as soil improvement. Therefore, developing a water-based fire extinguishing agent that combines high-efficiency fire extinguishing, good flame-retardant properties, ecological restoration functions, and strong adhesion has become an urgent need in the fire protection field. Summary of the Invention

[0005] In view of this, the present invention aims to provide a spore gel water-based fire extinguishing agent with ecological restoration function to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0017] The objective of this invention can also be achieved through the following technical measures:

[0018] In step (1), the chitosan is dissolved by magnetic stirring, and the cross-linking liquid is slowly stirred when the chitosan-seed stock solution is added dropwise. The reaction temperature is room temperature.

[0019] The objective of this invention can also be achieved through the following technical measures:

[0020] In step (2), the temperature is 60°C when dissolving sodium carboxymethyl cellulose and 50°C when adding gelatin. The nanomaterials are pre-dispersed by high-speed stirring and the gel is prepared by magnetic stirring.

[0021] The objective of this invention can also be achieved through the following technical measures:

[0022] In step (3), the microcapsules are dispersed by low-speed mechanical stirring, and the dopamine is activated by gentle stirring. The reaction temperature is room temperature.

[0023] The objective of this invention can also be achieved through the following technical measures:

[0024] A fire extinguishing method using a spore-gel water-based fire extinguishing agent with ecological restoration function extinguishes fire through a synergistic mechanism of expansion flame retardancy, physical isolation, biomimetic adhesion, and temperature-sensitive diffusion: Ammonium polyphosphate decomposes upon heating to generate phosphoric acid, which promotes the dehydration and carbonization of lignin; melamine decomposes to generate non-combustible gas, which drives the expansion of the char layer to form a heat-insulating and oxygen-barrier char layer; biochar and montmorillonite enhance the heat insulation performance; the temperature-sensitive gel formed by gelatin covers the surface of the burning material, and the evaporation of water absorbs heat and lowers the temperature; dopamine polymerizes under weakly alkaline conditions to form a polydopamine network, which makes the gel firmly adhere to the surface of the burning material; the temperature-sensitive properties of gelatin reduce the viscosity of the gel at high temperatures, allowing it to automatically diffuse into the burning gaps.

[0025] The objective of this invention can also be achieved through the following technical measures:

[0026] Chitosan, as the microcapsule wall material, forms an encapsulation structure through electrostatic cross-linking, while providing basic adhesion. Sodium tripolyphosphate, as a cross-linking curing agent, interacts electrostatically with chitosan to solidify the microcapsule structure.

[0027] The objective of this invention can also be achieved through the following technical measures:

[0028] Sodium carboxymethyl cellulose serves as a gel thickening framework, forming a stable three-dimensional network structure; ammonium polyphosphate, as a highly efficient flame retardant, decomposes upon heating to produce phosphoric acid and non-combustible gases, inhibiting combustion; lignin, as a char source, forms a char layer at high temperatures to insulate against heat and oxygen; melamine, as a highly efficient flame retardant, decomposes to produce non-combustible gases such as ammonia, diluting the oxygen concentration.

[0029] The objective of this invention can also be achieved through the following technical measures:

[0030] The dopamine hydrochloride, as a biomimetic adhesion core, undergoes oxidative polymerization under weakly alkaline conditions to form a polydopamine network, imparting super strong adhesion. The dilute ammonia water, as a pH adjuster, adjusts the pH of the system to 8.0-8.5, activating dopamine polymerization.

[0031] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions:

[0032] 1. Multi-dimensional functional integration: It integrates high-efficiency flame retardancy, biomimetic adhesion, physical heat insulation, temperature-sensitive self-diffusion and ecological restoration, breaking through the single-function limitations of traditional fire extinguishing agents.

[0033] 2. Innovative ecological restoration: The addition of drought-resistant grass seeds / spore microcapsules, and the synergistic effect of Caragana korshinskii, Alternanthera philoxeroides, and Agrostis chinensis, can improve the soil in a long-term manner and realize a closed loop of "fire extinguishing-ecological reconstruction", which is rare in existing technologies.

[0034] 3. Upgraded flame retardant performance: Lignin replaces starch as the carbon source, forming a graphitized dense carbon layer, which significantly improves flame retardant efficiency and heat insulation, and is superior to traditional intumescent flame retardant systems.

[0035] 4. Bionic Adhesion Technology: By introducing a dopamine polymerization mechanism, the gel possesses a "mussel-inspired" super strong adhesion force, which allows it to adhere persistently to complex surfaces and improve fire extinguishing stability.

[0036] 5. Sustainable development advantages: Utilizing agricultural waste to extract lignin and building a "waste-to-treasure" circular economy model is more environmentally friendly and lower in cost than solutions that rely on food crops (such as starch).

[0037] 6. Nanoscale synergistic effect: The nanoscale dispersion of montmorillonite and biochar enhances the strength and thermal insulation of the char layer, improving the overall fire extinguishing performance, reflecting the cross-innovation of nanotechnology and flame retardant materials.

[0052] The preparation method of a spore gel water-based fire extinguishing agent with ecological restoration function according to the present invention includes the following steps:

[0053] (1) Preparation of Group A ecological microcapsules: Add 75 parts by volume of 1% acetic acid solution to a container, add 1.5 parts of chitosan until dissolved while stirring, add 1.5 parts of drought-resistant grass seeds / spores, and stir for 15 minutes; dissolve 5 parts of sodium tripolyphosphate in 100 parts by volume of deionized water to prepare a cross-linking solution, add the chitosan-seed stock solution dropwise into the cross-linking solution, stir and solidify for 30 minutes, filter and wash until neutral, and drain for later use;

[0054] (2) Preparation of Group B functional gel matrix: Add 1.5 parts montmorillonite, 3.0 parts biochar, and 4.0-6.0 parts lignin to 30 parts deionized water and sonicate for 20-30 minutes to form a suspension; add 70 parts deionized water to a container, heat to 60°C, add 4.0 parts sodium carboxymethyl cellulose in batches, stir for 30 minutes until transparent, maintain 60°C, add 8.0 parts ammonium polyphosphate and 3.0 parts melamine in sequence, stir for 20 minutes, cool to 50°C, add 4.0 parts gelatin and 1.0 part soybean lecithin, stir for 15 minutes, add the above suspension, and stir for 15 minutes;

[0055] (3) Preparation and compounding of group C: Cool the gel of group B to 25-30℃, add the microcapsules of group A, and disperse by stirring at a low speed of <200rpm; dissolve 0.75 parts of dopamine hydrochloride in 5 parts of water, add it to the gel and stir for 5 minutes, add dilute ammonia dropwise until the pH of the system is 8.0-8.5, stir for 1-2 hours, and let it stand at room temperature for 24 hours to solidify;

[0056] In step (1), chitosan is dissolved by magnetic stirring, and the cross-linked liquid is slowly stirred when adding chitosan-seed stock solution. The reaction temperature is room temperature. In step (2), sodium carboxymethyl cellulose is dissolved at 60°C, gelatin is added at 50°C, nanomaterials are pre-dispersed by high-speed stirring, and gel is prepared by magnetic stirring. In step (3), microcapsules are dispersed by low-speed mechanical stirring, dopamine is activated by gentle stirring, and the reaction temperature is room temperature.

[0057] A fire extinguishing method for a spore-gel water-based fire extinguishing agent with ecological restoration function: Fire extinguishing through a synergistic mechanism of expansion flame retardancy, physical isolation, biomimetic adhesion, and temperature-sensitive diffusion: Ammonium polyphosphate decomposes upon heating to generate phosphoric acid, promoting the dehydration and carbonization of lignin; melamine decomposes to produce non-combustible gases, propelling the carbon layer to expand and form a heat-insulating and oxygen-barrier carbon layer; biochar and montmorillonite enhance the heat insulation performance; the temperature-sensitive gel formed by gelatin covers the surface of the burning material, and the evaporation of moisture absorbs heat and lowers the temperature; dopamine polymerizes under weakly alkaline conditions to form a polydopamine network, enabling the gel to firmly adhere to the surface of the burning material; the temperature-sensitive properties of gelatin reduce the viscosity of the gel at high temperatures, allowing it to automatically diffuse into the burning gaps;

[0058] Sodium carboxymethyl cellulose serves as a gel thickening framework, forming a stable three-dimensional network structure; ammonium polyphosphate, as a highly efficient flame retardant, decomposes upon heating to produce phosphoric acid and non-combustible gases, inhibiting combustion; lignin, as a char source, forms a char layer at high temperatures to insulate against heat and oxygen; melamine, as a highly efficient flame retardant, decomposes to produce non-combustible gases such as ammonia, diluting the oxygen concentration.

[0059] Dopamine hydrochloride, as a biomimetic adhesion core, undergoes oxidative polymerization under weakly alkaline conditions to form a polydopamine network, giving it super strong adhesion. Dilute ammonia water is used as a pH adjuster to adjust the pH of the system to 8.0-8.5, thereby activating dopamine polymerization.

[0060] The following are several specific embodiments of the application of the present invention.

[0061] Example 1: Application in fire suppression and ecological restoration after forest fires

[0062] Application scenario: Small to medium-sized surface fires in forests caused by lightning strikes, involving leaf litter and low shrubs, with acidic red soil. The fires need to be extinguished to prevent soil erosion and restore vegetation.

[0063] Proportioning and practical function:

[0064] Group A ecological microcapsules were composed of 1.5 parts chitosan, 1.5 parts Caragana korshinskii seeds, 75 parts by volume of 1% acetic acid solution, and 5 parts sodium tripolyphosphate (prepared into a 100-part, 5% solution). Chitosan, as the microcapsule wall material, cross-links with sodium tripolyphosphate to form an encapsulation structure, encapsulating the Caragana korshinskii seeds within. This protects the seeds from high-temperature damage during firefighting, and the basic adhesive force provided by chitosan allows the microcapsules to adhere to the surface of fallen leaves and shrubs.

[0065] In Group B functional gel matrix, 4.0 parts of sodium carboxymethyl cellulose form a stable three-dimensional network structure, supporting 8.0 parts of ammonium polyphosphate, 3.0 parts of melamine, 5.0 parts of lignin, 1.5 parts of montmorillonite, 3.0 parts of biochar, 4.0 parts of gelatin, and 1.0 part of soybean lecithin. Ammonium polyphosphate decomposes upon heating to produce phosphoric acid, promoting the dehydration and carbonization of lignin. Melamine decomposes to produce non-combustible gases, driving the expansion of the char layer and forming a stable heat-insulating layer on the surface of the leaf litter. The 5.0 parts of lignin have a moderate char-forming efficiency, effectively blocking heat transfer. Montmorillonite and biochar enhance heat insulation, while biochar improves acidic red soil. Gelatin reduces gel viscosity at high temperatures, and combined with the reduced surface tension from 1.0 part of soybean lecithin, allows the gel to automatically diffuse into leaf litter gaps, increasing the extinguishing range. The three-dimensional network of sodium carboxymethyl cellulose ensures the stability of the gel structure, facilitating spraying operations.

[0066] In Group C, 0.75 parts of dopamine hydrochloride, after adjusting the pH to 8.2 with dilute ammonia, undergo oxidative polymerization to form a polydopamine network, giving the fire extinguishing agent super strong adhesion, allowing it to firmly adhere to the tree trunk and ground surface, forming a flame-retardant layer that lasts for more than 60 minutes and prevents reignition.

[0067] Usage and effects:

[0068] Using a backpack sprayer, spray at a rate of 1.5-2.0L per square meter to extinguish open flames within 30 seconds. Grass seeds germinated 7 days after extinguishing the fire, with a germination rate of 85% on day 30 and a vegetation coverage of 60% on day 90. There was no reignition, and the vegetation recovery rate was 30% faster than in areas where fires were extinguished using traditional methods. Soil organic matter increased by 5%.

[0069] Example 2: Application of rapid fire suppression and vegetation reconstruction in grassland fires

[0070] Application scenario: Large-scale fires during the summer drought in Inner Mongolia's grasslands, where the burning materials are herbaceous plants such as needlegrass and sheepgrass, leaving the ground bare and at high risk of wind erosion.

[0071] Proportioning and practical function:

[0072] Group A contains 1.5 parts chitosan, 1.5 parts a mixture of alfalfa and crested wheatgrass (1:1), 75 parts by volume of 1% acetic acid solution, and 5 parts sodium tripolyphosphate (prepared into 100 parts by volume of 5% solution). The microcapsules formed by chitosan and sodium tripolyphosphate encapsulate the mixed grass seeds. Alfalfa has strong nitrogen-fixing ability, and crested wheatgrass exhibits outstanding drought resistance. The synergistic effect of these two components promotes grassland vegetation restoration, and the microcapsules protect the grass seeds during fire suppression.

[0073] Group B contains 100 parts by volume of deionized water, 4.0 parts of sodium carboxymethyl cellulose, 8.0 parts of ammonium polyphosphate, 4.0 parts of lignin, 3.0 parts of melamine, 1.5 parts of montmorillonite, 3.0 parts of biochar, 4.0 parts of gelatin, and 1.0 part of soybean lecithin. The 4.0 parts of lignin are suitable for thin-layer covering after herbaceous plant combustion. After charring, it forms a composite layer with montmorillonite and biochar, enhancing wind erosion resistance and reducing wind erosion by more than 70% under level 5 winds. The flame-retardant system of ammonium polyphosphate and melamine rapidly inhibits combustion, while gelatin and soybean lecithin promote rapid gel spreading on the grassland surface. The 4.0 parts of sodium carboxymethyl cellulose ensure the structural stability of the gel when sprayed over large areas.

[0074] Group C, 0.75 parts of dopamine hydrochloride, formed a polydopamine network when the pH was adjusted to 8.0, which enhanced the adhesion of the fire extinguishing agent to the grassland surface and extended the protection time.

[0075] Usage and effects:

[0076] The drone swarm sprayed 10L per acre, extinguishing surface flames within 20 seconds. Grass seeds germinated 5 days after the fire was extinguished, with a germination rate of 82% on day 20 and vegetation cover of 75% on day 60. There were no secondary fires within one month, and the primary productivity of the grassland recovered to 80% of the pre-fire level, while soil nitrogen content increased by 12%.

[0077] Example 3: Firefighting and Protection Applications in Fires of Ancient Wooden Buildings

[0078] Application scenario: Localized fire in a group of ancient wooden buildings in southern China, with the burning parts being the wooden components of beams, columns, and eaves. The fire needs to be extinguished, secondary damage minimized, and the spread of flames prevented.

[0079] Proportioning and practical function:

[0080] Group A consists of 1.5 parts chitosan, 1.5 parts mixed grass seeds of Caragana korshinskii and Amaranthus spp. (2:1), 75 parts by volume of 1% acetic acid solution, and 5 parts sodium tripolyphosphate (prepared into 100 parts by volume of 5% solution). The grass seeds encapsulated in microcapsules can germinate in the green belts around ancient buildings.

[0081] In Group B, 6.0 parts of lignin formed a dense char layer. Together with ammonium polyphosphate and melamine, it formed a strong char layer on the surface of wooden components, carbonizing only the surface of the components and protecting the internal structure, thus avoiding cracking caused by traditional water extinguishing. The thermosensitive properties of gelatin at high temperatures allowed the gel to spread rapidly into the gaps of the components. The three-dimensional network of sodium carboxymethyl cellulose ensured the stability of the gel during high-pressure spraying. Montmorillonite and biochar enhanced the strength and thermal insulation of the char layer.

[0082] The polydopamine network formed by group C dopamine hydrochloride allows the extinguishing agent to adhere firmly to wooden components, continuously exerting its flame-retardant effect and preventing the spread of flames.

[0083] Usage and effects:

[0084] Using a high-pressure water gun with a special nozzle, 2.5L of water was sprayed per square meter, controlling the spread of the flames within 15 seconds. More than 90% of the wooden components were successfully saved, the fire did not spread, and the grass germination rate in the surrounding green belt reached 80% on the 10th day, forming a green firebreak after 30 days.

[0085] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
