The mixing process has a crucial impact on the performance of tire rubber, mainly reflected in the following aspects:
1、 Affects wear resistance and aging resistance
During the mixing process, raw materials such as rubber, carbon black, and additives need to be mixed according to precise formulas. During this process, the control of temperature, time, and stirring speed is crucial, directly affecting the quality and performance of the rubber material. The control of mixing uniformity and process parameters has an important impact on the wear resistance and aging resistance of tires. If the mixing is uneven, it may lead to local performance differences of tire rubber, thus affecting the overall wear resistance and aging resistance of the tire.
2、 Affects the structural integrity and balance of tires
After mixing, tire rubber needs to go through a molding process to form the prototype of the tire. The accuracy of molding and the stability of the process are related to the structural integrity and balance of the tire. If the mixing process is improper, it may affect the flowability and plasticity of the rubber material during the molding process, thereby affecting the structural integrity and balance of the tire, leading to problems such as tire shaking when driving at high speeds.
3、 Affects the strength and elasticity of tires
Vulcanization is a crucial step in the production process of tires. During the vulcanization process, rubber molecules undergo cross-linking reactions, which endow tires with good physical and chemical properties such as strength, hardness, elasticity, etc. The quality of the mixing process will directly affect the vulcanization effect. If the mixing process is improper, it may lead to incomplete or excessive vulcanization, thereby affecting the strength and elasticity of the tire.
4、 Affects the energy efficiency and environmental friendliness of tires
With the increasing awareness of environmental protection, the energy efficiency and environmental friendliness of tires are receiving more and more attention. In the mixing process, the energy efficiency and environmental friendliness of tires can be improved by adding specific additives or changing the formula. For example, the use of chemical rubber refining process can further increase the amount of white carbon black in tires, thereby saving the consumption of fossil materials and achieving energy conservation and emission reduction. At the same time, liquid-liquid mixing improves the dispersion of fillers and additives in rubber, thereby significantly enhancing product performance, including energy efficiency and environmental friendliness.
In conclusion, the influence of mixing process on the properties of tire rubber is various, including wear resistance, aging resistance, structural integrity and balance, strength and elasticity, energy conservation and environmental protection. Therefore, in the production process of tires, it is necessary to strictly control the parameters and conditions of the mixing process to ensure the production of high-performance tire products.
