Description

Tire recycling methods, storage media, electronic devices, and computer product programs

[0001] This application claims priority to Chinese Patent Application No. 202411597689.0, filed on November 8, 2024, entitled "Tire Recycling Method, Storage Medium, Electronic Device and Computer Product Program", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of tire recycling technology, and more specifically, to a tire recycling method, storage medium, electronic device, and computer product program. Background Technology

[0003] One of the core processes in tire manufacturing is vulcanization, which chemically crosslinks elastomer molecular chains to build a stable three-dimensional network structure, thereby endowing tires with excellent mechanical properties and durability. However, the irreversible nature of the vulcanization process means that the vulcanized rubber in waste tires cannot be directly reprocessed by melting or dissolving, which constitutes a major technical obstacle to tire recycling. Since the invention of vulcanized rubber, the recycling and reuse of waste tires has been a persistent problem for the rubber industry, requiring a breakthrough.

[0004] Currently, waste tire recycling technologies are mainly divided into three categories: rubber shredding, reuse, and desulfurization. Desulfurization technology aims to break down the polysulfide, disulfide, and monosulfide bonds in vulcanized rubber. For rubber vulcanized with peroxides or resins, it is necessary to break down even stronger carbon-carbon bonds or other chemical bonds. However, desulfurized rubber often suffers from a decline in quality due to the breakage of its molecular chains and the expansion of its molecular weight distribution, thus limiting its applications and making it difficult to use as a raw material for high-performance rubber products. Summary of the Invention

[0005] The main objective of this application is to provide a tire recycling method, storage medium, electronic device, and computer product program to solve the problem in the prior art that the rubber after desulfurization is difficult to use as a raw material for high-performance rubber products due to the breakage of rubber molecular chains and the expansion of molecular weight distribution.

[0006] To achieve the above objectives, according to one aspect of this application, a tire recycling method is provided, comprising:

[0007] Waste tires are collected and pre-processed to obtain waste materials to be recycled;

[0008] A first set amount of waste to be recycled, a first set concentration of solvent, a second set amount of functionalized compound, and a third set amount of catalyst are added to a batch reactor, and a chemical reaction is carried out under the first set conditions to obtain the first product system.

[0009] The first product system is then post-processed to obtain the product.

[0010] The first set conditions include: a reaction time of 1 to 6 hours and a reaction temperature of 80°C to 120°C.

[0011] Furthermore, the functional group at one end of the functionalized compound is any one of maleic anhydride, thiol, or amine, and the other end of the functionalized compound is a group that has the functions of dispersing filler, anti-aging, or anti-sulfurization reaction.

[0012] Further, the steps of obtaining waste tires and pre-processing them to obtain the waste material to be recycled include:

[0013] Waste tires are crushed to obtain initial waste to be recycled. The initial waste to be recycled can be any one or more of the following shapes: block, flake, and powder.

[0014] The initial waste material to be recycled is dried at a set drying temperature to obtain the waste material to be recycled;

[0015] The drying temperature is set at 100℃.

[0016] Furthermore, prior to the step in which the chemical reaction occurs under the first set conditions, the following is also included:

[0017] An inert gas is introduced into the batch reactor to remove oxygen from the reactor.

[0018] The inert gas is either nitrogen or carbon dioxide, or...

[0019] The inert gas is a mixture of nitrogen and carbon dioxide.

[0020] Furthermore, the residence time of the inert gas in the batch reactor is controlled to be 30 min; and / or,

[0021] The number of times inert gas is introduced into the batch reactor is set to at least 3 times, and the time interval between each two adjacent introductions of inert gas is 5 to 30 minutes.

[0022] Furthermore, the solvent is any one of alkanes, haloalkanes, and lipids; and / or,

[0023] The initial set concentration is 5% to 40%.

[0024] Further, the steps of post-processing the first product system to obtain the product include:

[0025] An alcohol is introduced into a batch reactor and mixed with the first product system to obtain the product and the initial solvent.

[0026] Among them, alcohols are any one of methanol, ethanol, propanol, butanol, pentanol, and hexanol.

[0027] Furthermore, after obtaining the product and solvent, the process also includes:

[0028] The initial solvent is sequentially separated and distilled to obtain the final solvent.

[0029] Furthermore, the initial waste materials to be recycled were all between 50 mesh and 200 mesh in size.

[0030] Furthermore, the third set amount is 1 / 100 to 1 / 8000 of the total molar amount of the functionalized compound.

[0031] According to another aspect of this application, a computer-readable storage medium is provided, wherein a computer program is stored in the computer program, which is configured to execute the above-described tire recycling method when it is run.

[0032] According to another aspect of this application, an electronic device is provided, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the tire recycling method described above through the computer program.

[0033] According to another aspect of this application, a computer program product is also provided, including a computer program that, when executed by a processor, describes the tire recycling method.

[0034] By applying the technical solution of this application, the pretreatment stage of waste tires, through steps such as crushing and drying, effectively improves the uniformity and reactivity of the raw materials, making subsequent chemical reactions more efficient. During the chemical reaction stage, by controlling the reaction time within 1 to 6 hours and the reaction temperature within the range of 80°C to 120°C, the reaction process can be precisely controlled, ensuring the sufficiency and selectivity of the reaction, avoiding excessive byproducts due to over-reaction, and also avoiding low recycling efficiency due to under-reaction. The addition of functionalized compounds and catalysts not only promotes the decomposition of waste tire components but also introduces new functional groups through functionalization reactions, improving the performance of the desulfurized rubber, thus giving the recycled rubber a wider range of applications, especially in fields with high performance requirements, such as high-performance tire manufacturing and rubber product modification. Furthermore, by optimizing reaction conditions and the use of chemical substances, the tire recycling method of this application achieves high-efficiency recycling while significantly reducing energy consumption and environmental pollution, meeting the requirements of sustainable development and demonstrating significant economic and social benefits.

[0035] In summary, the tire recycling method provided in this application not only improves the efficiency and purity of waste tire recycling, but also improves the performance of recycled rubber and broadens its application scope by introducing functionalized compounds and catalysts.

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] One of the core processes in tire manufacturing is vulcanization, which chemically crosslinks elastomer molecular chains to build a stable three-dimensional network structure, thereby endowing tires with excellent mechanical properties and durability. However, the irreversible nature of the vulcanization process means that the vulcanized rubber in waste tires cannot be directly reprocessed by melting or dissolving, which constitutes a major technical obstacle to tire recycling. Since the invention of vulcanized rubber, the recycling and reuse of waste tires has been a persistent problem for the rubber industry, requiring a breakthrough.

[0041] Currently, waste tire recycling technologies are mainly divided into three categories: rubber shredding, reuse, and desulfurization. Desulfurization technology aims to break down the polysulfide, disulfide, and monosulfide bonds in vulcanized rubber. For rubber vulcanized with peroxides or resins, it is necessary to break down even stronger carbon-carbon bonds or other chemical bonds. However, desulfurized rubber often suffers from a decline in quality due to the breakage of its molecular chains and the expansion of its molecular weight distribution, thus limiting its applications and making it difficult to use as a raw material for high-performance rubber products.

[0042] The main objective of this application is to provide a tire recycling method, storage medium, electronic device, and computer product program to solve the problem in the prior art that the rubber after desulfurization is difficult to use as a raw material for high-performance rubber products due to the breakage of rubber molecular chains and the expansion of molecular weight distribution.

[0043] The method embodiments provided in this application can be executed on a computer terminal, mobile terminal, or similar computing device. Taking running on a computer terminal as an example, FIG1 is a hardware structure block diagram of a computer terminal for a tire recycling method according to an embodiment of this application. As shown in FIG1, the computer terminal may include one or N (only one is shown in FIG1) processors 102 (processors 102 may include, but are not limited to, microprocessors (Central Processing Unit, CPU) or programmable gate arrays (FPGAs), etc.) and a memory 104 for storing data. The computer terminal may also include a transmission device 106 for communication functions and an input / output device 108. Those skilled in the art will understand that the structure shown in FIG1 is only illustrative and does not limit the structure of the computer terminal. For example, the computer terminal may also include more or fewer components than shown in FIG1, or have a different configuration than shown in FIG1.

[0044] The memory 104 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the network point adjustment method in this embodiment. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, thus implementing the above-described method. The memory 104 may include high-speed random access memory and non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include memory remotely located relative to the processor 102, and these remote memories can be connected to a computer terminal via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

In another example, the transmission device 106 may be a Radio Frequency (RF) module used for wireless communication with the Internet.

[0046] First, this application provides a tire recycling method, as shown in Figure 2, the tire recycling method includes:

[0047] S1. Obtain waste tires and pre-process them to obtain waste materials to be recycled;

[0048] Specifically, the waste tires are crushed to obtain initial waste to be recycled. The initial waste to be recycled can be any one or more of the following shapes: block, flake, and powder.

[0049] The initial waste material to be recycled is dried at a set drying temperature to obtain the waste material to be recycled;

[0050] The drying temperature is set at 100℃.

[0051] Specifically, the waste tires are crushed using a rubber crushing device to obtain initial waste to be recycled. The initial waste to be recycled can be any one or more of the following shapes: block, flake, or powder. The size of the initial waste to be recycled is between 50 mesh and 200 mesh, which helps to increase the efficiency and uniformity of the chemical reaction in subsequent processing. Then, the initial waste to be recycled is dried at a drying temperature of 100°C to remove the moisture from the initial waste to obtain the waste to be recycled.

[0052] Through the technical solution of this application, waste tires are no longer a burden on the environment, but become a reusable resource, which is of great significance for promoting the circular economy and sustainable development.

[0053] S2. Add the first set amount of waste to be recycled, the first set concentration of solvent, the second set amount of functionalized compound, and the third set amount of catalyst to the batch reactor, and introduce inert gas into the batch reactor to remove oxygen from the reactor.

[0054] The inert gas is either nitrogen or carbon dioxide, or a mixture of nitrogen and carbon dioxide, and a chemical reaction is carried out under the first set conditions to obtain the first product system.

[0055] The residence time of the inert gas in the batch reactor is controlled to be 30 min; and / or,

[0056] The number of times inert gas is introduced into the batch reactor is set to be at least 3 times, and the time interval between each two adjacent introductions of inert gas is 5 min to 30 min.

[0057] The solvent is any one of alkanes, halogenated hydrocarbons, and esters; and / or, the first set concentration is 5% to 40%; one end of the functionalized compound has a functional group of maleic anhydride, mercapto, or amino, and the other end of the functionalized compound has a group that has the functions of dispersing filler, anti-aging, or anti-sulfurization reaction.

[0058] Optionally, the catalyst can be one or more of a metal ion compound and an amination reagent. Further, the metal ion compound can be a compound containing any one of palladium, copper, nickel, platinum, ruthenium, zinc, and magnesium ions, and the amination reagent can be a thiodiimide, such as N,N′-dimethoxycarbonyl thiodiimide (DMSD) or N,N′-di-tert-butoxycarbonyl thiodiimide (DTSD).

[0059] Specifically, it is essential to ensure that all chemical reactions take place in an oxygen-free environment to prevent oxidation side reactions during the reaction process. This can be achieved by introducing an inert gas (such as nitrogen, carbon dioxide, or a mixture of both) into the batch reactor. The residence time of the inert gas in the reactor should be controlled to be at least 30 minutes to fully displace the oxygen within the reactor and ensure the inertness of the reaction environment. Furthermore, introducing the inert gas multiple times (at least three times), with a time interval of 5 to 30 minutes between adjacent introductions, can further improve the efficiency of oxygen removal and ensure the smooth progress of the reaction.

[0060] Next, a first predetermined amount of waste material to be recycled (e.g., pretreated waste tire debris), a first predetermined concentration of solvent (e.g., alkanes, halogenated hydrocarbons, or lipid solvents, with a concentration between 5% and 40%), a second predetermined amount of functionalized compound, and a third predetermined amount of catalyst are added to the reactor. The selection of functionalized compounds should consider that one end of their functional groups can react with the components in the waste tire material, while the other end possesses groups such as dispersing fillers, anti-aging agents, or anti-sulfurization reaction groups to improve the performance of the recycled material. The addition of a catalyst can accelerate the reaction and improve reaction efficiency.

[0061] Under the set reaction conditions (i.e., the first set conditions, reaction time 1 to 6 hours, reaction temperature 80℃ to 120℃), these components will undergo a chemical reaction to generate the first product system. To further improve the purity and recovery rate of the product, after the reaction, ethanol can be added to the reactor and mixed with the first product system to precipitate or separate the product, while simultaneously recovering the solvent. The recovered solvent can be recycled after separation, distillation, and other steps, thereby reducing the overall process cost. The third set amount is 1 / 100 to 1 / 8000 of the total molar amount of the functionalized compound. The first set concentration is determined based on the smallest unit of the rubber molecular structure. The second set amount needs to be determined based on the reactive site equivalent. In chemical reactions, especially those involving polymer materials, the "reactive site equivalent" usually refers to the number of specific structures in the molecule participating in the reaction that can chemically react with another reactant. For functionalized compounds in the tire recycling process, reactive sites refer to chemical groups that can react with rubber molecules (usually vulcanized rubber) in waste tires, such as maleic anhydride, mercapto, or amine groups. These groups can react with the vulcanization points or other specific functional groups on the rubber molecular chain, thereby achieving chemical modification or functionalization of the rubber. Determining the initial solvent concentration requires consideration of the smallest unit of the rubber's molecular structure. The specific steps are as follows: First, understand the type and molecular structure of the rubber in waste tires. Different types of rubber (such as natural rubber, styrene-butadiene rubber, etc.) have different structural characteristics and smallest repeating units. Based on the rubber's molecular structure, determine its reactive sites, such as vulcanization points or other functional groups. Assuming a fixed amount of waste tires, determine the total number of active sites in the waste through chemical analysis or theoretical calculations. Based on the rubber's solubility and the properties of the reactive sites, select a suitable solvent. The solvent's properties should promote or not affect the reaction between the functionalized compound and the rubber. The initial solvent concentration is to ensure that the functionalized compound can fully contact and react with the active sites in the rubber molecules. When calculating the solvent concentration, the following factors need to be considered: the solubility of the functionalized compound in the solvent; the reaction compatibility of the solvent with the functionalized compound and the catalyst; the density of active sites and the reactivity of the functionalized compound, i.e., ensuring that the active groups of the functionalized compound can effectively react with each active site. The first set concentration of the solvent defined in this application is between 5% and 40%.

[0062] The tire recycling method described in this application utilizes functionalized compounds and catalysts to effectively recycle waste tires under mild reaction conditions. This avoids excessive breakage of rubber molecular chains and expansion of molecular weight distribution that may occur in traditional recycling methods, thereby improving the quality of the recycled materials. Furthermore, by controlling the reaction environment to be anaerobic, the occurrence of oxidation side reactions can be reduced, further ensuring product purity. Solvent recovery and reuse reduce production costs and improve economic efficiency. Overall, the method described in this application not only solves the technical challenges of waste tire recycling but also has environmental and economic advantages, which is of great significance for promoting the sustainable development of the tire industry.

[0063] S3. Post-process the first product system to obtain the product;

[0064] Specifically, the process involves: introducing an alcoholic substance into a batch reactor and mixing it with the first product system to obtain the product and the initial solvent; then, the initial solvent is sequentially separated and distilled to obtain the final solvent.

[0065] Among them, alcohols are any one of methanol, ethanol, propanol, butanol, pentanol, and hexanol.

[0066] The first set conditions include: a reaction time of 1 to 6 hours and a reaction temperature of 80°C to 120°C.

[0067] Specifically, at the end of the reaction, an alcohol is immediately introduced into the reaction vessel. The alcohol can be any one of methanol, ethanol, propanol, butanol, pentanol, or hexanol. One of these alcohols can be selected to combine with the first product system, and its amount should be sufficient to fully mix with the first product system, altering the chemical environment of the system and promoting product precipitation or the formation of an easily separable phase. In this embodiment, ethanol is used. The amount and rate of ethanol addition need to be appropriately adjusted to avoid drastic temperature changes or pressure fluctuations, ensuring operational safety. After mixing, the product and solvent need to be separated by physical methods such as filtration and centrifugation. The product usually precipitates out as a precipitate or solid, while the solvent remains in the liquid phase. The solvent separated from the mixture needs to be further purified by distillation to remove impurities and restore its initial purity. Distillation is a separation technique based on the difference in boiling points of the components in a liquid mixture. By controlling temperature and pressure, high-purity solvents can be effectively separated and recovered.

[0068] The solvent recovery and reuse in this application reduces chemical consumption, lowers processing costs, and minimizes potential environmental pollution, embodying the concepts of green chemistry and a circular economy. By introducing functionalized compounds and specific post-processing steps, the molecular weight distribution of the products can be controlled, avoiding the performance degradation caused by rubber molecular chain breakage in traditional tire recycling methods. This results in recycled rubber with properties closer to virgin rubber, expanding its application range. Inert gas (such as nitrogen) is introduced into the reactor to remove oxygen, reducing the risk of explosion or combustion within the system and ensuring operational safety. This method combines chemical reaction and physical separation techniques, achieving selective chemical bond breaking and efficient product separation during tire recycling. Compared to traditional methods, it offers higher conversion rates and selectivity, providing a new pathway for the high-value utilization of waste tires.

[0069] Example 1

[0070] Add 1 kg of recovered solution-polymerized styrene-butadiene desulfurized rubber and 1-10 g of maleic anhydride as an antioxidant with one end group to the reactor. Heat the reactor at 50°C for 30 min, connect a nitrogen storage device, and purge with nitrogen 3-5 times under vacuum. Add purified hexane (purified hexane, i.e., hexane formed after removing water and oxygen) under a nitrogen atmosphere, stir and heat to the reaction temperature (80°C to 120°C), inject the catalyst toluene solution, and react for 3-6 hours. After termination, sedimentation, drying, and purification, the desulfurized solution-polymerized styrene-butadiene-maleic anhydride-antioxidant compound is obtained. Analysis after extraction revealed a grafting rate ranging from 2% to 20%, making it suitable as an additive. Specifically, the energy conversion rate of the rubber tube was calculated using nuclear magnetic resonance (NMR), a method already known and not detailed here. The catalyst, a toluene solution, refers to a solution formed by dissolving the catalyst in toluene. Toluene solution better disperses the catalyst, allowing it to uniformly contact the waste to be recycled, thus effectively catalyzing the chemical reaction and facilitating the reaction between functionalized compounds and components in waste tires, achieving better recycling results. Toluene, as a good organic solvent, can dissolve various organic substances, including rubber and some catalysts, and is one of the commonly used solvents in chemical reactions. Maleic anhydride has the CAS number 108-31-6, MDL MFCD00005518, and is manufactured by Energy Chemical.

[0071] Example 2

[0072] One kilogram of recovered desulfurized natural rubber and 10-15 g of an antioxidant with a thiol end group were added to a reactor. The reactor was heated to 50°C for 30 minutes, and a nitrogen storage device was connected. Nitrogen was purged 3-5 times under vacuum. Purified hexane (hexane that has been purified by removing water and oxygen) was added under a nitrogen atmosphere. The mixture was stirred and heated to the reaction temperature (80°C to 120°C). A toluene catalyst solution was injected, and the reaction was allowed to proceed for 0.5-3 hours. After termination, sedimentation, drying, and purification, the desulfurized natural rubber-monosulfur bond-antioxidant compound was obtained. Analysis after extraction revealed a grafting rate in the range of 3%-30%. The thiol group has the CAS number 68865-60-1 and is manufactured by Energy Chemical.

[0073] Example 3

[0074] One kilogram of recovered solution-polymerized styrene-butadiene desulfurized rubber and 2-8 g of maleic anhydride-terminated surfactant were added to a reactor. The reactor was heated to 50°C for 30 minutes. A nitrogen storage device was connected, and nitrogen was purged 3-5 times under vacuum. Purified hexane was added under a nitrogen atmosphere, and the mixture was stirred and heated to the reaction temperature. A toluene catalyst solution was injected, and the reaction was allowed to proceed for 2-5 hours. After termination, sedimentation, drying, and purification, the desulfurized solution-polymerized styrene-butadiene-maleic anhydride-surfactant compound was obtained. Analysis after extraction revealed a grafting rate in the range of 2%-25%.

[0075] Example 4

[0076] Using the PCR (Passenger Car Radial) tread compound as a baseline, 20 grams of a desulfurized solution-polymerized styrene-butadiene-maleic anhydride-surfactant compound was used to replace an equal amount of the SBR in the compound for mixing, resulting in a control sample. The prepared baseline and control samples were extracted with acetone and compared before and after aging. It was found that the tensile volume of the sample with the added desulfurized solution-polymerized styrene-butadiene-maleic anhydride-surfactant compound was increased by 15% compared to the baseline sample.

[0077] Specifically, PCR (Passenger Car Radial) refers to radial tires for passenger cars. The tread compound formulation is the rubber compound used to manufacture the tire tread layer, typically carefully designed based on tire performance requirements (such as wear resistance, wet grip, and rolling resistance). Here, the original formulation is used as a baseline to compare the effects of the improvements. Desulfurized solution-polymerized styrene-butadiene (SBR) is a recycled rubber obtained by chemically treating waste tires. Maleic anhydride is a compound that can improve the properties of polymer materials, while surfactants can enhance the dispersibility and compatibility of materials. Combining these three and replacing an equal amount of SBR in the original formulation means replacing a portion of the original rubber with recycled rubber while maintaining the total mass of the formulation, to test its performance. Mixing is the process of thoroughly mixing rubber with various additives (such as carbon black, vulcanizing agents, and accelerators) at high temperatures. Two samples were prepared: a baseline sample prepared according to the original formulation and a control sample with a portion of the SBR replaced by the aforementioned compounds. Acetone extraction is a commonly used method for separating additives and non-rubber components from rubber. After extraction, the samples undergo aging treatment to simulate performance changes under usage conditions, typically including prolonged high-temperature, light-exposed, or mechanical stress tests. Tensile product is an indicator that measures the product of tensile strength and elongation at break of a rubber material under tension, reflecting its overall tensile properties. The control sample showed a 15% higher tensile product than the baseline sample before and after aging, indicating that the recycled rubber material with the addition of a desulfurized solution-polymerized styrene-butadiene-maleic anhydride-surfactant compound exhibits improved performance compared to pure SBR material, particularly in terms of abrasion resistance and mechanical strength.
