Modification of Silica with Combination

Hits: 649 img

Combination modification is to modify the combination of silica and other materials to improve the overall performance of rubber products by combining their respective advantages. This method can combine the advantages of the two modifiers to enhance the comprehensive properties of the matrix, but the modification effect is closely related to the modifier ratio.

For example, carbon black and white carbon black are both good reinforcing agents for the rubber industry. Among them, carbon black is one of the most commonly used reinforcing agents in the rubber industry. The special structure of carbon black can enhance the tensile and tear strength of rubber materials. Improve its wear resistance, cold resistance and other properties; while silica as a reinforcing agent can significantly improve the rolling resistance and wet skid resistance of rubber products, but its effect alone is not as good as carbon black. A large number of studies have shown that the combination of carbon black and silica as a reinforcing agent can combine the advantages of the two to improve the overall performance of rubber products.
