Problems solved by technology

With the development of the economy, there are strict requirements on the performance of cables. The aging resistance, elasticity and toughness of traditional nitrile rubber cable materials cannot meet the requirements of the society, resulting in a short service life of the cable materials, which brings great harm to the actual use. Therefore, it is necessary to improve the existing nitrile rubber cable materials to meet the diverse requirements of the cable market.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a liquid rubber modified nitrile rubber cable material. Background technique [0002] Nitrile rubber is prepared by emulsion polymerization of butadiene and acrylonitrile. It has high oil resistance, abrasion resistance, good heat resistance and strong adhesion. It has been widely used in cable materials. With the development of the economy, there are strict requirements on the performance of cables. The aging resistance, elasticity and toughness of traditional nitrile rubber cable materials cannot meet the requirements of the society, resulting in a short service life of the cable materials, which brings great harm to the actual use. Therefore, it is necessary to improve the existing nitrile rubber cable materials to meet the diverse requirements of the cable market. Contents of the invention [0003] The invention provides a liquid rubber modified nitrile rubber cabl...
