Description

technical field [0001] The invention relates to the technical field of materials, in particular to a high-performance modified styrene-butadiene rubber material. Background technique [0002] Styrene butadiene rubber, also known as polystyrene butadiene copolymer, has excellent wear resistance, heat resistance, aging resistance and vulcanization speed. It is an important rubber matrix material and has been widely used in tires, tapes, hoses, wires and cables. and other fields. With the development of economy, cables are widely used in various industries and fields. During the processing, storage and use of cables, due to the combined effects of various external factors, cable materials are prone to aging, performance degradation, wear and tear, etc., which have gradually attracted people's attention. With the development of society, people have higher and higher requirements for cables. Although styrene-butadiene rubber has excellent performance, its performance as a cable...
