Abstract

The invention relates to the technical field of rubber, particularly to a composite rubber reinforcing system, styrene butadiene rubber using the reinforcing system and a preparation method of the styrene butadiene rubber. The styrene butadiene rubber comprises raw materials in parts by weight as follows: 100 parts of styrene butadiene rubber, 40 parts of carbon black, 2-10 parts of chitin, 10 parts of cashew nut oil, 3 parts of zinc oxide, 1-3 parts of stearic acid, 1-3 parts of an accelerant, 1-3 parts of an anti-aging agent and 1-3 parts of sulfur. According to the composite reinforcing system, the chitin and the carbon black are combined together through chemical bonds and hydrogen bonds by the aid of reactions of surface groups of the chitin and the carbon black, a special reinforcing structure with a chitin network used as a base and the carbon black, attached to the chitin network, used as reinforcing points is formed, the rubber performance is improved, meanwhile, the carbon black is not required to be modified before usage, the environmental protection property of a product is improved, and the usage cost is reduced.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a composite rubber reinforcing system, styrene-butadiene rubber using the reinforcing system and a preparation method of the styrene-butadiene rubber. Background technique [0002] Carbon black is a widely used industrial material, widely used in industries such as rubber, plastics and coatings. Due to the strong self-aggregation between carbon black particles, it is difficult to disperse uniformly in the polymer matrix, which limits the scope of its application. Therefore, by modifying the abundant polar groups existing on the surface of carbon black particles , reducing the degree of adsorption between carbon black particles, and improving the dispersion efficiency and stability of carbon black in the polymer matrix are of great significance for improving the comprehensive performance of carbon black reinforced polymers. [0003] In the prior art, active surface agents, surface...
