Silica is used in colored rubber products to replace carbon black for reinforcement, to meet the needs of white or translucent products. Silica also has strong adhesion, tear resistance and heat resistance and anti-aging properties, so in the black rubber products can also replace part of the carbon black, in order to obtain high-quality rubber products, such as off-road tires, engineering tires, radial tires and so on.
Rubber is a kind of elastomer with excellent elasticity, but its comprehensive performance is not satisfactory, the production of rubber products usually need to be added to the rubber in the process of carbon black to improve the strength, abrasion resistance and aging resistance, but due to the addition of carbon black to make the products are black, and the grade is not high. The introduction of gas-phase silica in China has laid a material foundation for the production of a new generation of rubber products with novel color and excellent performance. Add a small amount of fumed silica in ordinary rubber, the strength of the product, abrasion resistance and aging resistance and other properties have reached or exceeded the high-grade rubber products, and can keep the color unchanged for a long time. Nano-modified color EPDM waterproofing roll-roofing, its abrasion resistance, tensile strength, folding resistance, anti-aging properties have improved significantly, and bright colors, excellent color retention effect. The development of color tires has also made some progress, such as tire side rubber folding resistance from the original 100,000 times to more than 500,000 times, is expected in the near future, the realization of domestic automobile and motorcycle tires colored.
