(4) Interfacial modification of macromolecules
Macromolecular surface modification using modifying agent is a kind of macromolecular polymer containing polar groups, in the process of reaction with modified silica particles, macromolecular interface modifier of the main chain of the molecule to the introduction of more polarity of epoxide group at the same time keep the basic main chain structure, in order to improve the compatibility between white carbon black particles and matrix, achieve a good effect on surface modification.
(5) and modified
Carbon black and white carbon black are good reinforcing agents in rubber industry, among which carbon black is one of the most commonly used reinforcing agents in rubber industry. The special structure of carbon black can enhance the tensile and tear strength of rubber materials and improve its wear resistance, cold resistance and other properties. As a reinforcing agent, white carbon black can significantly improve the rolling resistance and wetting resistance of rubber products, but its effect is not as good as that of carbon black alone.
A large number of studies have shown that using carbon black and silica as reinforcing agents can improve the overall properties of rubber products by combining their advantages.
