Rubber is an elastomer with excellent elasticity, but its comprehensive properties are not satisfactory. In the process of producing rubber products, carbon black is usually added to the rubber to improve strength, abrasion resistance and aging resistance. The addition of black makes the products black, and the grade is not high. The advent of fumed silica in China has laid a material foundation for the production of new-generation rubber products with novel colors and excellent performance. 添加 After adding a small amount of fumed silica to ordinary rubber, the strength, abrasion resistance and aging resistance of the product have reached or exceeded the high-grade rubber products, and the color can be maintained for a long time. The nano-modified color EPDM waterproof membrane has significantly improved abrasion resistance, tensile strength, folding resistance, and aging resistance, and has bright colors and excellent color retention effects. The development of colored tires has also made some progress. For example, the flex resistance of the tire side rubber has been increased from 100,000 times to more than 500,000 times. It is expected that in the near future, the colorization of domestic automobile and motorcycle tires will be realized.
