Problems solved by technology

At the same time, this product can also be used for the modification of rubber products, plastic products, petroleum resins, etc., and is widely used in the fields of tires, tapes, hoses, wires and cables, medical appliances and various rubber products. The styrene-butadiene rubber material for tires still cannot meet the demand. How to prepare a high-performance styrene-butadiene rubber material for tires with high bearing strength, strong toughness, high hardness, anti-skid, and excellent heat resistance has become a technical problem that needs to be solved at present.

Description

technical field [0001] The invention relates to the technical field of styrene-butadiene rubber, in particular to a styrene-butadiene rubber composite material for high-performance tires and a preparation method thereof. Background technique [0002] Styrene-butadiene rubber (SBR), also known as polystyrene butadiene copolymer, its physical structure performance, processing performance and product performance are close to natural rubber, and some properties such as wear resistance, heat resistance, aging resistance and vulcanization speed are faster Natural rubber is more excellent and can be used together with natural rubber and various synthetic rubbers. Styrene-butadiene rubber is the most produced general-purpose synthetic rubber, including emulsion polystyrene butadiene rubber and solution polystyrene butadiene rubber. Styrene-butadiene rubber is a light yellow-brown elastic solid. The density increases with the increase of styrene content. It has poor oil resistance bu...
