How to improve the quality of tire rubber products?

Improving the product quality of tire rubber is a comprehensive process that involves multiple aspects such as formula adjustment, production process optimization, and raw material selection. Here are some specific suggestions:

1、 Optimize formula

Choose the appropriate rubber type: Commonly used rubber types in tire rubber include natural rubber (NR), butadiene rubber (BR), styrene butadiene rubber (SBR), etc. According to the usage environment and performance requirements of the tire, reasonable combination of these rubber types can improve the wear resistance, cold resistance, elasticity, etc. of the tire. For example, adding a certain amount of butadiene rubber to the composite of tire reclaimed rubber/natural rubber/styrene butadiene rubber can significantly improve the flexural flexibility of the composite.

Adjusting the dosage of additives: Additives such as carbon black, zinc oxide, Gumaron resin, accelerators, etc. have a significant impact on the performance of tire rubber. By adjusting the dosage of these additives, the physical and mechanical properties of tire rubber can be optimized. For example, increasing the amount of high abrasion resistant carbon black can significantly improve the wear resistance of tires; The use of liquid Gumaron resin can enhance the adhesion and aging resistance of tire rubber.

2、 Improve production process

Optimizing the rubber mixing process: Rubber mixing is a key link in tire rubber production. By optimizing the rubber mixing process, such as improving the mixing effect, controlling the rubber mixing temperature and time, it is possible to ensure uniform dispersion of the rubber material and improve its physical and mechanical properties. It is recommended to use a two-stage mixing method, which first mixes other additives except sulfur and accelerators on the internal mixer, and then stops for a period of time before adding sulfur and accelerators in the two-stage mixing to obtain a better quality mixed rubber.

Strengthening the control of vulcanization process: vulcanization is another important link in tire rubber production. By controlling parameters such as vulcanization temperature, time, and pressure, it is possible to ensure that tire rubber is fully vulcanized, improving the strength and wear resistance of the vulcanized rubber. At the same time, pay attention to selecting good accelerators and try to achieve a matching vulcanization speed to take into account the characteristics of different rubber types.

3、 Select high-quality raw materials

Choose high-quality raw rubber: Raw rubber is the main raw material for tire rubber, and its quality directly affects the performance of tire rubber. Therefore, raw rubber with high purity, low impurity content, and good tensile strength should be selected.

Reasonable use of recycled rubber: Recycled rubber is an ideal raw material for reducing costs in the rubber product industry, which is processed from waste tires. Reasonable use of recycled rubber in tire rubber production can reduce raw material costs while maintaining or improving the performance of tire rubber. However, attention should be paid to the dosage and quality control of recycled rubber to avoid negative effects on tire performance.

4、 Quality control and testing

Establish a strict quality control system: from raw material procurement, production process to finished product testing, establish a strict quality control system to ensure that every link meets quality standards.

Strengthen finished product testing: Conduct strict testing on tire rubber products, including physical and mechanical performance testing, wear resistance testing, cold resistance testing, etc., to ensure that product quality meets relevant standards and customer requirements.

In summary, improving the product quality of tire rubber requires starting from multiple aspects such as formula adjustment, production process optimization, raw material selection, and quality control and testing. Through continuous efforts and innovation, the product quality of tire rubber can be continuously improved to meet market demand and customer expectations.
