TECHNICAL FIELD

[0001] The present application relates to the technical field of high polymer materials, in particular to a high-efficiency energy-saving radial tire vulcanization capsule and a production process thereof. BACKGROUND

[0002] The Tire Industry Policy of China issued in 2010 clearly states that the development of safe, energy-saving, and environmentally friendly high-performance radial tires is encouraged. By 2015, the radialization rate of passenger car tires will reach 100%, the radialization rate of light-duty truck tires will reach 85%, and the radialization rate of heavy-duty truck tires will reach 90%.

[0003] The tire vulcanization capsule faces a core technical problem in the context of high-performance tire manufacturing: how to ensure high thermal conductivity of the capsule to shorten the vulcanization time while improving its aging resistance and production efficiency to meet the needs of frequent recycling and high-quality tire production.

[0004] The traditional vulcanization capsule has insufficient thermal conductivity, resulting in long vulcanization time, low production efficiency, and direct impact on tire manufacturing capacity and cost control. At the same time, the aging resistance of the capsule is poor, and it is difficult to withstand more than 550 cycles under high temperature and high pressure, which easily causes cracking or performance degradation, increasing the frequency of replacement and maintenance costs. In addition, the lack of flowability of the rubber compound prolongs the mold closing time, the vulcanization process stability is poor, and the quality of the capsule is difficult to maintain consistency, especially in the context of high-performance tires with high requirements for size accuracy and uniformity, process fluctuations will lead to a decrease in tire quality or even scrap.

[0005] These problems are interrelated, and the lack of thermal conductivity directly prolongs the vulcanization time, while poor flowability further exacerbates the bottleneck of production efficiency; the lack of aging resistance limits the long-term reliability of the capsule in high-strength production environments.

[0006] The above problems collectively constitute a technical contradiction: while improving thermal conductivity to speed up vulcanization, how to avoid accelerated aging of the capsule due to high temperature and high pressure or frequent use, while ensuring the flowability of the rubber compound and process stability, to achieve an efficient, stable, and durable production process, to meet the stringent requirements of high-performance tire manufacturing on the performance of the capsule.

DETAILED DESCRIPTION

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1 As shown, this embodiment of a high-efficiency and energy-saving radial tire vulcanizing bladder and its manufacturing process may specifically include: A high-efficiency energy-saving radial tire vulcanizing bladder comprises, by weight, the following components: Butyl rubber: 40-60 parts; Low-unsaturation butyl rubber: 30-60 parts; Neoprene rubber: 3-10 parts; Carbon black N330: 10-20 parts; Acetylene black: 40-60 parts; Aluminum oxide: 5-10 parts; Castor oil: 5-10 parts; Stearic acid: 0.5-1.5 parts; Zinc oxide: 5-10 parts; Resin: 6-10 parts.

[0021] Preferably, the total number of butyl rubber and low-unsaturation butyl rubber is 70-120 parts, wherein the low-unsaturation butyl rubber has a higher degree of unsaturation, which is used to improve the heat aging resistance of the rubber compound.

[0022] The thickness of the tire vulcanizing bladder is within the standard design range and is usually determined according to the bladder's specifications and dimensions.

[0023] This invention discloses a production process for high-efficiency and energy-saving radial tire vulcanizing bladders, such as... Figure 1 As shown, the specific steps include: Step S1: Obtain the formulation raw materials, which include butyl rubber, acetylene black, graphite and alumina. The formulation raw materials improve the thermal conductivity by replacing ordinary carbon black with acetylene black, graphite and alumina. Step S2: Obtain butyl rubber with a high degree of unsaturation, wherein the butyl rubber with a high degree of unsaturation is used to improve the aging resistance. Step S3: Add glutenin and coumarone resin, wherein glutenin and coumarone resin are used to optimize the flowability of the rubber compound. Step S4: Shorten the mold closing time and increase the vulcanization temperature by modifying the equipment. The vulcanization temperature is 200℃-220℃. The vulcanization temperature and mold closing time are used to reduce the vulcanization time. Step S5, performing mixing, extrusion and vulcanization steps to obtain the high-efficiency energy-saving radial tire vulcanization capsule.

[0024] High thermal conductivity: By using high thermal conductivity acetylene carbon black and aluminum oxide (composite instead of part of ordinary carbon black), the thermal conductivity of the capsule is significantly improved, which can reach more than 0.5 W / (m·K), which is beneficial to rapid heat transfer, shortens the tire vulcanization time, and saves energy.

[0025] Long service life: By using low unsaturation butyl rubber to replace traditional butyl rubber, the heat aging resistance of the rubber compound is improved, and the service life of the capsule is greatly improved, which can reach more than 550 times after testing.

[0026] High temperature resistance: The formula system can resist high temperature vulcanization conditions of 200-210℃, further shortening the vulcanization time of the capsule itself and improving the production efficiency.

[0027] Excellent comprehensive performance: While significantly improving the thermal conductivity and service life, the physical and mechanical properties and process processing performance are maintained. The product has been certified by many well-known tire enterprises.

[0028] Significant economic benefits: Shortening the tire vulcanization time by about 0.5 minutes, improving the production efficiency, reducing the unit energy consumption, meeting the national energy-saving and environmental protection industrial policy, and achieving significant economic and social benefits.

[0029] The method is described in detail in combination with specific examples to show its implementability and advantages. The method optimizes the formula raw materials, adjusts the unsaturation of butyl rubber, improves the flowability of the rubber compound, and optimizes the vulcanization process to prepare a tire vulcanization capsule with high thermal conductivity and excellent aging resistance.

[0030] Step S1, obtain the formula raw material, the formula raw material includes butyl rubber, acetylene carbon black, graphite and alumina, the formula raw material is obtained by replacing ordinary carbon black with acetylene carbon black, graphite and alumina to improve the thermal conductivity. Specifically, the selection of the formula raw material directly affects the thermal conductivity and mechanical properties of the tire vulcanization capsule. Butyl rubber as the main base material is widely used in tire vulcanization capsules due to its excellent sealing and heat resistance. Ordinary carbon black is often used as a filler in traditional formulations, but the thermal conductivity of ordinary carbon black is limited and it is difficult to meet the needs of high-efficiency vulcanization process. Therefore, acetylene carbon black, graphite and alumina are selected as thermal conductive fillers in this embodiment. Acetylene carbon black has high thermal conductivity and good dispersibility, graphite can effectively transfer heat due to its layered structure, and alumina further enhances heat conduction and improves the wear resistance of the rubber compound. By mixing these three fillers in a specific ratio and replacing ordinary carbon black, the thermal conductivity of the rubber compound can be significantly improved, thereby shortening the vulcanization time. For example, in one possible implementation, the addition amount of acetylene carbon black, graphite and alumina is controlled at 10%, 5% and 3% of the total amount of the formula, respectively, to ensure the balance of thermal conductivity and mechanical strength. It should be noted that the selection of the formula raw material also needs to consider the adaptability of production equipment and process conditions, for example, the dispersion ability of the mixing equipment will affect the uniformity of the filler.

[0031] Step S11, obtain butyl rubber as the main base material, the content of the butyl rubber accounts for a major proportion of the formula raw material. Specifically, butyl rubber is the core material of the tire vulcanization capsule, and its content usually accounts for more than 50% of the total amount of the formula to ensure the elasticity and air tightness of the rubber compound. In one embodiment, butyl rubber with a higher molecular weight is selected, with a molecular weight range of 300,000 to 500,000, to ensure that the rubber compound has sufficient strength and stability during high-temperature vulcanization. For example, when producing small tire vulcanization capsules, butyl rubber with a molecular weight of about 400,000 can be selected, with a content of 55% of the total amount of the formula, to balance the processing performance and mechanical properties. In another embodiment, for large tire vulcanization capsules, the butyl rubber content can be appropriately increased to 60% to enhance the pressure resistance of the capsule. The selection of butyl rubber needs to be optimized according to the size and use scenario of the target capsule, for example, in heavy truck tire production, high-temperature resistance and fatigue resistance need to be considered first.

[0032] Step S12, acetylene carbon black, graphite and aluminum oxide are obtained as the heat-conducting filler, and the acetylene carbon black, graphite and aluminum oxide are mixed in a predetermined ratio. In one possible implementation, the mixing ratio of acetylene carbon black, graphite and aluminum oxide is 10:5:3 to ensure the balance of heat conduction performance and dispersion of the rubber compound. The acetylene carbon black has a high specific surface area and a thermal conductivity coefficient, and its particle size is usually between 20 and 50 nanometers, which can effectively fill the small gaps in the rubber compound and improve the heat transfer efficiency. The layered structure of graphite forms a heat-conducting network in the rubber compound, further enhancing the heat conduction capacity. The aluminum oxide can improve the durability of the capsule due to its high hardness and wear resistance. For example, in one embodiment, acetylene carbon black with a specific surface area of 80 square meters per gram, graphite with a particle size of 2 microns, and aluminum oxide with a particle size of 1 micron are mixed in the above ratio and added to the rubber compound. High-shear mixing equipment is required during the mixing process to ensure uniform dispersion of the filler in the butyl rubber matrix. It should be noted that the ratio of the filler can be adjusted according to the target thermal conductivity, for example, when higher thermal conductivity is pursued, the proportion of acetylene carbon black can be increased to 12%, while the proportion of graphite can be reduced to 4%.

[0033] Step S13, chlorobutyl glue, castor oil, stearic acid, zinc oxide and resin are obtained as auxiliary materials for adjusting the physical properties of the rubber compound. Specifically, chlorobutyl glue as auxiliary rubber can enhance the adhesion and oil resistance of the rubber compound, and its addition amount is usually controlled at 5% to 10% of the total amount of the formula. Castor oil as a plasticizer can improve the processing flowability of the rubber compound, and the addition amount is generally 2% to 5%. Stearic acid and zinc oxide are respectively used as activators and accelerators to accelerate the vulcanization reaction and increase the crosslinking density of the rubber compound, and their addition amounts are controlled at 1% to 2% and 3% to 5% respectively. Resin is used to adjust the viscosity and hardness of the rubber compound, and phenolic resin or rosin resin is commonly used, with an addition amount of 2% to 4%. For example, in one embodiment, 5% chlorobutyl glue, 3% castor oil, 1.5% stearic acid, 4% zinc oxide and 3% phenolic resin are selected, and these auxiliary materials are uniformly mixed with butyl rubber and heat-conducting filler through a mixing device. It should be noted that the proportion of auxiliary materials needs to be adjusted according to the specific use of the rubber compound, for example, in the high-temperature vulcanization scenario, the content of zinc oxide can be appropriately increased to improve the vulcanization efficiency.

[0034] Step S14, determine the content range of each component in the formula raw material, the content range is pre-set according to the target thermal conductivity coefficient and mechanical properties. In one possible implementation, the content range of the formula raw material is as follows: butyl rubber 50% to 60%, acetylene carbon black 8% to 12%, graphite 4% to 6%, alumina 2% to 4%, neoprene 5% to 10%, castor oil 2% to 5%, stearic acid 1% to 2%, zinc oxide 3% to 5%, and resin 2% to 4%. These content ranges are obtained through experimental optimization to balance the thermal conductivity coefficient, mechanical strength, and processing performance. For example, when producing high-thermal-conductivity tire vulcanization capsules, butyl rubber 55%, acetylene carbon black 10%, graphite 5%, alumina 3%, neoprene 6%, castor oil 3%, stearic acid 1.5%, zinc oxide 4%, and phenolic resin 3% can be selected. By detecting the thermal conductivity coefficient and tensile strength of the rubber compound, it is verified whether the formula meets the target performance requirements. It should be noted that the determination of the formula proportion also needs to be combined with the mixing capacity of the production equipment and the vulcanization process conditions, for example, in a high-shear mixing device, the filler proportion can be appropriately increased to improve the thermal conductivity performance.

[0035] Step S2, obtain butyl rubber with higher unsaturation, which is used to improve the aging resistance. Specifically, the unsaturation of butyl rubber directly affects its aging resistance and vulcanization characteristics. Butyl rubber with higher unsaturation can form more crosslinking points due to its higher double bond content in the molecular chain, thereby improving the heat resistance and aging resistance of the rubber compound. In one embodiment, butyl rubber with an unsaturation of 2.0% is selected, which has a higher double bond content than ordinary butyl rubber (unsaturation of about 1.0%) and can maintain stable mechanical properties in a high-temperature vulcanization environment. For example, in the production of heavy-duty tire vulcanization capsules, butyl rubber with an unsaturation of 2.2% is selected to ensure that the capsules still have good elasticity after multiple high-temperature vulcanization cycles. It should be noted that too high unsaturation may increase the hardness of the rubber compound, so the processing performance and aging resistance need to be balanced through formula adjustment.

[0036] Step S21, obtain low unsaturation butyl rubber and high unsaturation butyl rubber, and mix the low unsaturation butyl rubber and the high unsaturation butyl rubber according to a preset ratio. In one possible implementation, the low unsaturation butyl rubber (with an unsaturation of about 1.0%) and the high unsaturation butyl rubber (with an unsaturation of about 2.0%) are mixed at a ratio of 3:2 to balance the aging resistance and the processing fluidity. For example, when producing a medium tire vulcanization capsule, 60% of the low unsaturation butyl rubber and 40% of the high unsaturation butyl rubber are selected and preliminarily mixed by a mixing device. The mixing temperature needs to be controlled to be between 80 and 100 degrees Celsius to avoid premature crosslinking of the rubber molecular chains. It should be noted that the mixing ratio can be adjusted according to the specific use of the capsule. For example, in a high-temperature and high-frequency vulcanization scenario, the proportion of the high unsaturation butyl rubber can be increased to 50%.

[0037] Step S22, determine the double bond content of the high unsaturation butyl rubber, and use the double bond content to ensure the aging resistance. Specifically, the double bond content is an important indicator for measuring the unsaturation of butyl rubber, and is usually detected by infrared spectroscopy or nuclear magnetic resonance technology. In one embodiment, butyl rubber with a double bond content of 2.0% to 2.5% is selected, and the aging resistance of the butyl rubber can meet the long-term use requirements of the tire vulcanization capsule in a high-temperature environment. For example, in the detection process, it is confirmed that butyl rubber with a double bond content of 2.2% can withstand more than 550 vulcanization cycles without significant performance degradation. It should be noted that the selection of the double bond content needs to be combined with the vulcanization process parameters. For example, when the vulcanization temperature is high, the double bond content can be appropriately reduced to avoid excessive crosslinking.

[0038] Step S23, pretreat the high unsaturation butyl rubber, and the pretreatment includes adjusting the molecular structure of the high unsaturation butyl rubber before mixing. In one possible implementation, the pretreatment is achieved by low-temperature kneading and adding a stabilizer to improve the molecular chain distribution and processing performance of the butyl rubber. For example, during the kneading process, the temperature is controlled to be between 60 and 80 degrees Celsius, and 0.5% of an antioxidant is added to prevent oxidation of the rubber during the pretreatment. After the pretreatment, the molecular chains of the butyl rubber are more uniform, and the butyl rubber can be better combined with fillers in subsequent mixing. In another embodiment, for high unsaturation butyl rubber, the pretreatment time can be extended to 30 minutes to further optimize the molecular structure. It should be noted that the optimization of the pretreatment conditions needs to be adjusted according to the molecular weight and unsaturation of the butyl rubber.

[0039] Step S24, adjust the formula proportion according to the characteristics of the butyl rubber with higher unsaturation, the formula proportion is used to optimize the stability and heat resistance of the rubber compound. Specifically, the butyl rubber with higher unsaturation may cause the hardness of the rubber compound to increase due to its higher crosslinking density, so the performance needs to be optimized by adjusting the proportion of auxiliary materials. In one embodiment, for butyl rubber with an unsaturation of 2.2%, the castor oil content is increased to 4% to improve the flowability of the rubber compound, while the stearic acid content is reduced to 1% to avoid excessive hardening. For example, when producing heavy tire vulcanization capsules, the formula proportion is adjusted to butyl rubber 55%, acetylene carbon black 10%, graphite 5%, aluminum oxide 3%, neoprene 6%, castor oil 4%, stearic acid 1%, zinc oxide 4%, and phenolic resin 3%. The adjusted formula can ensure the stability and aging resistance of the rubber compound during high-temperature vulcanization.

[0040] Step S3, add rubber easy and coumarone resin, which are used to optimize the flowability of the rubber compound. Specifically, rubber easy and coumarone resin as tackifiers and plasticizers can significantly improve the flowability of the rubber compound during mixing and extrusion, reducing the processing difficulty. In one possible implementation, the addition amount of rubber easy is 2% of the total formula, and the addition amount of coumarone resin is 3%, which are uniformly mixed with butyl rubber and fillers through mixing equipment. For example, when producing small tire vulcanization capsules, low molecular weight rubber easy and coumarone resin are selected to ensure the flowability of the rubber compound during low-temperature mixing. It should be noted that the addition amount of rubber easy and coumarone resin needs to be optimized according to the viscosity of the rubber compound and the performance of the processing equipment, for example, in a high-shear mixing equipment, the rubber easy content can be appropriately reduced to 1.5%.

[0041] Step S31, obtain rubber easy, the addition amount of which is pre-set according to the flowability requirements of the rubber compound. In one embodiment, rubber easy with a molecular weight of 1000 to 2000 is selected, and the addition amount is 1.5% to 2.5% of the total formula. Rubber easy can reduce the viscosity of the rubber compound and improve its flowability during extrusion. For example, when producing medium-sized tire vulcanization capsules, rubber easy with an addition amount of 2% is selected, which is mixed with the raw rubber through mixing equipment at 100 degrees Celsius, and the mixing time is controlled within 10 minutes. It should be noted that the addition amount of rubber easy needs to be adjusted according to the initial viscosity of the rubber compound, for example, in a formula with higher viscosity, the rubber easy content can be increased to 2.5%.

[0042] Step S32, obtain coumarone resin, the amount of coumarone resin is added according to the viscosity requirements of the rubber. Specifically, coumarone resin can maintain the stability of the rubber in high temperature mixing due to its excellent tackifying property and heat resistance. In one possible implementation, coumarone resin with a softening point of 90 degrees Celsius is selected, and the addition amount is 2% to 4% of the total amount of the formula. For example, when producing heavy tire vulcanization capsules, coumarone resin with an addition amount of 3% is selected, mixed with raw rubber and gum easy by mixing equipment, and the mixing temperature is controlled at 110 to 120 degrees Celsius. It should be noted that the amount of coumarone resin needs to be optimized with gum easy to avoid too low or too high viscosity of the rubber.

[0043] Step S33, mix the gum easy and coumarone resin with raw rubber, which is completed by mixing equipment. In one embodiment, a closed mixing machine is used for mixing, the mixing temperature is controlled at 100 to 120 degrees Celsius, and the mixing time is 8 to 12 minutes to ensure that the gum easy and coumarone resin are fully integrated with the butyl rubber. For example, when producing small tire vulcanization capsules, the mixing temperature is set to 110 degrees Celsius, and the mixing time is 10 minutes. The gum easy and coumarone resin are added in stages during the mixing process to improve dispersion uniformity. In another embodiment, for large tire vulcanization capsules, the mixing time can be extended to 12 minutes to ensure the uniformity of the rubber with high filler content. It should be noted that the speed and shear force of the mixing equipment need to be adjusted according to the viscosity of the rubber, for example, in high viscosity rubber, the speed can be increased to 60 revolutions per minute.

[0044] Step S34, detect the flowability and viscosity of the rubber, which is used to verify the effect of adding gum easy and coumarone resin. Specifically, the flowability and viscosity of the rubber are detected by a Mooney viscometer or a rheometer to ensure that they meet the requirements of the extrusion and vulcanization process. In one possible implementation, the Mooney viscosity value is detected to be 40 to 60 ML (1+4, 100 degrees Celsius) to ensure the flowability of the rubber during extrusion. For example, when producing medium-sized tire vulcanization capsules, the detection result shows that the Mooney viscosity value is 50 ML, indicating that the addition amount of gum easy and coumarone resin is appropriate and can meet the subsequent processing requirements. It should be noted that if the detection result shows that the viscosity is too high, the gum easy content can be appropriately increased or the mixing temperature can be reduced to optimize the performance of the rubber.

[0045] Step S4, shorten the mold clamping time and increase the vulcanization temperature through equipment modification, said vulcanization temperature and mold clamping time are used to reduce the vulcanization time. Specifically, in the preparation process of tire vulcanization capsule, the vulcanization process is the key link to determine the production efficiency and product quality. The traditional vulcanization equipment takes a long time in the process of clamping and heating, which leads to a long overall production cycle. In this embodiment, the mold equipment is modified, the clamping mechanism and heating system are optimized to shorten the clamping time and increase the vulcanization temperature, thereby significantly reducing the vulcanization time. For example, in one possible implementation, the modified mold equipment adopts a hydraulic quick clamping system, the clamping time is shortened from 15 seconds of the traditional to 8 seconds, and the vulcanization temperature is increased from 160 degrees Celsius to 180 degrees Celsius. This optimization can accelerate the crosslinking reaction of the rubber compound and improve production efficiency. It should be noted that the equipment modification needs to be matched with the rubber compound formula, for example, the use of high thermal conductivity fillers can support higher vulcanization temperature, thereby further improving the vulcanization efficiency.

[0046] Step S41, obtain the modified mold equipment, said mold equipment is used to realize quick clamping. In one embodiment, the modified mold equipment adopts a high-precision hydraulic system, which shortens the response time of clamping action by optimizing the hydraulic oil circuit and control valve. For example, when producing medium-sized tire vulcanization capsules, a hydraulic mold equipment equipped with servo control is selected, which has a clamping speed of 0.5 meters per second and a clamping time controlled within 8 seconds. In another embodiment, for large-sized tire vulcanization capsules, a mold equipment driven by double hydraulic cylinders is selected to ensure stability and uniformity during clamping. It should be noted that the selection of mold equipment needs to consider the size of the capsule and the production scale, for example, single-cylinder hydraulic equipment can be used for small capsule production, while multi-cylinder system is required for large capsule to ensure uniform distribution of clamping force.

[0047] Step S42, determine the clamping time, said clamping time is shortened to within a preset threshold. Specifically, the clamping time is an important parameter affecting the vulcanization efficiency, and too long clamping time will slow down the production rhythm. In this embodiment, the clamping time is controlled within the range of 5 to 10 seconds through equipment modification. For example, when producing small-sized tire vulcanization capsules, the clamping time is set to 7 seconds, and a high-precision sensor is used to monitor the clamping process to ensure that the mold is completely closed without deviation. In another embodiment, for heavy-duty tire vulcanization capsules, the clamping time can be extended to 9 seconds to adapt to larger mold size and higher clamping force requirements. It should be noted that the setting of clamping time needs to be optimized in coordination with the vulcanization temperature to avoid uneven stress on the mold or insufficient filling of the rubber compound due to too fast clamping.

[0048] Step S43, adjust the vulcanization temperature to a preset range, which is used to accelerate the vulcanization reaction. In one possible implementation, the vulcanization temperature is set between 175 and 185 degrees Celsius to accelerate the cross-linking reaction of the butyl rubber molecular chain while avoiding over-vulcanization of the rubber compound. For example, when producing a medium-sized tire vulcanization capsule, the vulcanization temperature is set to 180 degrees Celsius, and with the use of high thermal conductivity fillers, the vulcanization time is shortened from the traditional 20 minutes to 15 minutes. In another embodiment, for heavy-duty tire vulcanization capsules with high requirements for high-temperature durability, the vulcanization temperature can be increased to 185 degrees Celsius, while the temperature fluctuation range is controlled within ±2 degrees Celsius through a precise temperature control system. It should be noted that the increase in vulcanization temperature needs to be matched with the heat resistance of the rubber compound formula, for example, butyl rubber with higher unsaturation can withstand higher vulcanization temperatures.

[0049] Step S44, verify the effect of the mold clamping time and the vulcanization temperature on the vulcanization efficiency, which is completed by detecting the performance of the vulcanization capsule. Specifically, the improvement of the vulcanization efficiency is directly reflected in the shortening of the vulcanization time and the stability of the capsule performance. In one embodiment, by preparing multiple groups of vulcanization capsule samples, tests are conducted at mold clamping times of 7 seconds, 9 seconds, and vulcanization temperatures of 175 degrees Celsius, 180 degrees Celsius, respectively, to detect the thermal conductivity, tensile strength, and aging resistance of the samples. For example, test results show that the sample with a mold clamping time of 7 seconds and a vulcanization temperature of 180 degrees Celsius has a 25% shorter vulcanization time, a thermal conductivity of 0.5 W / M.K, and a tensile strength of 12 MPa, meeting the production requirements. It should be noted that professional detection equipment such as a thermal conductivity tester and a universal tensile testing machine needs to be used during the verification process to ensure the accuracy of the data.

[0050] Step S441, obtain samples of the vulcanization capsule, which are prepared by the modified equipment. In one possible implementation, using the modified hydraulic mold equipment and temperature control system, multiple groups of vulcanization capsule samples are prepared, each group being produced at different mold clamping times and vulcanization temperatures. For example, when producing small-sized tire vulcanization capsules, three groups of samples are prepared, respectively using mold clamping times of 7 seconds, vulcanization temperatures of 178 degrees Celsius, and mold clamping times of 8 seconds, vulcanization temperatures of 180 degrees Celsius, etc. After the sample preparation is completed, performance testing is immediately conducted to evaluate the effect of the equipment modification. It should be noted that sample preparation needs to be carried out in a stable production environment, for example, controlling the workshop temperature at 25 degrees Celsius and the humidity below 50% to avoid interference from external factors on the test results.

[0051] At step S442, the thermal conductivity of the sample is detected, which is used to evaluate the vulcanization efficiency. Specifically, the thermal conductivity is an important indicator for measuring the heat dissipation capacity of the vulcanization capsule, and directly affects the vulcanization time and the durability of the capsule. In an embodiment, a heat flow method thermal conductivity tester is used to detect the sample, and the test results show that the thermal conductivity of the sample using the acetylene carbon black, graphite and aluminum oxide formula is 0.34 to 0.36 watts per meter per Kelvin, which is about 40% higher than the traditional formula of 0.25 watts per meter per Kelvin. For example, under the conditions of 7 seconds of mold closing time and 180 degrees Celsius of vulcanization temperature, the thermal conductivity of the sample is 0.5 W / M.K, indicating that the synergistic effect of equipment modification and high thermal conductivity filler significantly improves the vulcanization efficiency. It should be noted that the thermal conductivity test needs to be repeated multiple times to ensure data reliability, for example, each group of samples is tested 3 times, and the average value is taken.

[0052] At step S443, the aging resistance performance of the sample is detected, which is verified by the number of cycles. In a possible implementation, by simulating the actual vulcanization process, the number of cycles of the sample under high temperature and high pressure environment is tested. For example, the sample is placed in a vulcanization environment of 180 degrees Celsius and 0.8 megapascals, simulating 550 vulcanization cycles, and detecting the attenuation of tensile strength and elastic modulus. The test results show that the sample using butyl rubber with an unsaturation of 2.2% has a tensile strength decrease of only 5% after 550 cycles, indicating excellent aging resistance performance. In another embodiment, for heavy-duty tire vulcanization capsules, the number of cycles is increased to 1500, and the sample can still maintain more than 90% of the initial performance. It should be noted that the aging resistance performance test needs to be combined with the actual use scenario, for example, higher cycle number needs to be considered in heavy-duty tire production.

[0053] At step S444, the vulcanization time reduction ratio of the sample is determined, which is used to confirm the improvement of production efficiency. Specifically, the shortening of vulcanization time is a direct manifestation of equipment modification and formula optimization. In an embodiment, by comparing the vulcanization time of the traditional process and the optimized process, the vulcanization time reduction ratio of the sample is calculated. For example, under the conditions of 7 seconds of mold closing time and 180 degrees Celsius of vulcanization temperature, the vulcanization time is shortened from 20 minutes to 14 minutes, with a reduction ratio of 30%. In another embodiment, for large tire vulcanization capsules, the vulcanization time is shortened from 25 minutes to 18 minutes, with a reduction ratio of 28%. It should be noted that the calculation of the vulcanization time reduction ratio needs to be combined with the actual operation data of the production equipment, for example, the time consumption of each vulcanization cycle is recorded.

[0054] Step S445, record the quality data of the sample, the quality data is used to optimize the subsequent production parameters. In one possible implementation, the quality data includes thermal conductivity, tensile strength, elastic modulus, aging resistance and vulcanization time and other indicators, and the formula and process parameters are optimized through data analysis. For example, the test results show that the sample with thermal conductivity of 0.5 W / (m·K) and tensile strength of 12 MPa meets the requirements of vulcanization time and aging resistance, and can be used as a standard parameter for subsequent production. In another embodiment, if the thermal conductivity of a certain group of samples is found to be low, the proportion of acetylene carbon black or the vulcanization temperature can be adjusted to optimize the performance. It should be noted that the recording of quality data needs to establish a database for regular analysis to continuously improve the production process.

[0055] Step S5, perform mixing, extrusion and vulcanization steps to obtain the tire vulcanization capsule. Specifically, mixing, extrusion and vulcanization are core process steps for preparing tire vulcanization capsules, which need to ensure the uniformity, molding accuracy and performance stability of the rubber compound. In one embodiment, a closed mixer is used in the mixing process, a high-precision extruder is used in the extrusion process, and the vulcanization process is completed in a modified mold equipment. For example, when producing medium-sized tire vulcanization capsules, the mixing time is controlled to be 12 minutes, the extrusion temperature is set to 100 degrees Celsius, and the vulcanization temperature is 180 degrees Celsius. Finally, a capsule with a thermal conductivity of 0.5 W / M.K and excellent aging resistance is obtained. It should be noted that each step needs to be closely linked, for example, the rubber compound after mixing needs to be immediately put into the extrusion process to avoid performance changes.

[0056] Step S51, perform raw rubber mixing, which uniformly mixes the formula raw materials. In one possible implementation, a closed mixer is used for raw rubber mixing, the mixing temperature is controlled to be 100 to 120 degrees Celsius, and the mixing time is 10 to 15 minutes. For example, when producing small tire vulcanization capsules, the mixing temperature is set to 110 degrees Celsius, the mixing time is 12 minutes, and the butyl rubber, thermal conductive filler and auxiliary materials are added in stages to ensure the uniformity of the rubber compound. In another embodiment, for large tire vulcanization capsules, the mixing time is extended to 15 minutes to improve the dispersibility of high filler content rubber compound. It should be noted that the temperature of the rotor and the mixing chamber needs to be monitored during the mixing process to avoid overheating of the rubber compound.

[0057] Step S52, carbon black and operating oil are added, which are used to enhance the processing performance of the rubber compound. Specifically, the addition of carbon black and operating oil can improve the flowability and plasticity of the rubber compound, facilitating subsequent extrusion molding. In one embodiment, acetylene black is selected as the main carbon black, and the addition amount is 10% of the total amount of the formula, and the operating oil is selected as the low-volatility castor oil, and the addition amount is 3%. For example, during the mixing process, acetylene black is first added and mixed for 5 minutes, and then castor oil is added and mixed for 3 minutes, to ensure that the two are fully integrated into the rubber compound. In another embodiment, for high-viscosity rubber compound, the operating oil content can be increased to 4% to further reduce the viscosity. It should be noted that the order and time of adding carbon black and operating oil need to be strictly controlled to avoid stratification or uneven performance of the rubber compound.

[0058] Step S53, two-stage mixing and filtering are performed to improve the uniformity of the rubber compound. In one possible implementation, the two-stage mixing is performed at low temperature, with the temperature controlled at 80 to 100 degrees Celsius, and the time is 5 to 8 minutes, and then the impurities in the rubber compound are removed by the filtering machine. For example, when producing medium-sized tire vulcanization capsules, the two-stage mixing temperature is set to 90 degrees Celsius, and the filtering machine screen size is 0.5 millimeters, to ensure the purity of the rubber compound. In another embodiment, for large capsules, the two-stage mixing time is extended to 8 minutes to improve the uniformity of the rubber compound. It should be noted that the filtering process needs to be checked regularly to avoid blockage affecting production efficiency.

[0059] Step S54, extrusion molding is performed to form the preliminary shape of the vulcanization capsule. Specifically, extrusion molding is achieved by a high-precision extruder, with the extrusion temperature controlled at 90 to 110 degrees Celsius, and the screw rotation speed is 30 to 50 revolutions per minute. In one embodiment, when producing small tire vulcanization capsules, the extrusion temperature is set to 100 degrees Celsius, the screw rotation speed is 40 revolutions per minute, and the die orifice is designed according to the size of the capsule to ensure the molding accuracy. In another embodiment, for large capsules, the screw rotation speed is reduced to 35 revolutions per minute to meet the extrusion needs of high-viscosity rubber compound. It should be noted that the rubber compound needs to be cooled immediately after extrusion molding to prevent shape deformation.

[0060] Step S55, a vulcanization treatment is performed to obtain a tire vulcanized capsule with a target thermal conductivity and service life. In one possible implementation, the vulcanization treatment is performed in the modified mold device, the vulcanization temperature is 178-182 degrees Celsius, and the vulcanization time is 14-16 minutes. For example, when producing a medium-sized tire vulcanized capsule, the vulcanization temperature is set to 180 degrees Celsius, and the vulcanization time is 15 minutes, to obtain a capsule with a thermal conductivity of 0.5 W / M.K and a tensile strength of 12 MPa. In another embodiment, for a heavy-duty tire vulcanized capsule, the vulcanization time is extended to 16 minutes to ensure that the crosslinking density meets the requirements. It should be noted that after the vulcanization is completed, cooling and demolding treatment is required to ensure that the surface of the capsule is smooth and defect-free.
