Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a nano-material modified natural rubber cable material. Background technique [0002] Natural rubber is a natural polymer compound mainly composed of polyisoprene. Natural rubber raw rubber has excellent comprehensive properties such as high strength and easy vulcanization, and the resulting products have excellent elasticity, high strength, high elongation, and small creep. With the improvement of people's requirements for the performance of rubber products, the tensile strength, hardness and aging resistance of natural rubber can not meet many practical requirements at present, and it needs to be modified. Contents of the invention [0003] The invention provides a nano-material modified natural rubber cable material, which has excellent mechanical properties and good aging resistance. [0004] The invention proposes a nano-material modified natural rubber cable mat...
