Problems solved by technology

[0002] Nitrile rubber is a rubber material synthesized by emulsion polymerization of butadiene and acrylonitrile monomers. Its molecular chain contains unsaturated double bonds and polar groups—CN, so it has excellent oil resistance and excellent Physical and mechanical properties, its oil resistance increases with the increase of the proportion of acrylonitrile monomer in nitrile rubber, but at the same time the weather resistance of nitrile rubber gradually decreases

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an impact-resistant, tear-resistant and high-weather-resistant cable. Background technique [0002] Nitrile rubber is a rubber material synthesized by emulsion polymerization of butadiene and acrylonitrile monomers. Its molecular chain contains unsaturated double bonds and polar groups—CN, so it has excellent oil resistance and excellent Its physical and mechanical properties, its oil resistance increases with the increase of the proportion of acrylonitrile monomer in nitrile rubber, but at the same time the weather resistance of nitrile rubber gradually decreases. [0003] When preparing the outer sheath of the cable, nitrile rubber is often used with other rubber materials due to its poor impact resistance and tear resistance. How to improve the impact resistance and tear resistance of the outer sheath of the cable while enhancing its Weather resistance has become the key direc...
