Problems solved by technology

[0002] During the processing, storage and use of rubber, due to the combined effects of various external factors, it is prone to aging and its properties gradually change, especially unsaturated carbon chain rubber, which is easily attacked by heat, oxygen and ozone, resulting in the deterioration of the molecular structure of rubber. Changes, butadiene rubber and styrene-butadiene rubber have poor weather resistance, are easily attacked by harsh external environments, and react to produce short chains or cross-links, resulting in performance degradation. How to prepare a kind of weather resistance, excellent tear resistance, pull Cable sheath materials with high tensile strength and good aging resistance have become technical problems that need to be solved at present
