Abstract

The invention discloses a semi-conductive shielding material for cables with good aging resistance, which relates to the technical field of cable shielding materials and mainly consists of nitrile rubber, butadiene rubber, conductive carbon black, tricresyl phosphate, decabromodiphenyl ether, Diformyl peroxide, antioxidant 1076, zinc stearate, antioxidant MB, calcium hexaboride, antimony trioxide, nano-diamond, titanium dioxide, carbon fiber, epoxy soybean oil. The semi-conductive shielding material for cables of the present invention uses nitrile rubber and butadiene rubber as the main raw materials. Butadiene rubber makes up for the deficiency of nitrile rubber in terms of cold resistance. Excellent performance, antimony trioxide, nano-diamond, calcium hexaboride, carbon fiber and other ingredients improve the flame resistance, oxidation resistance, chemical corrosion resistance and strength of the material, thereby increasing the service life of the product.

Description

technical field [0001] The invention relates to the technical field of cable shielding materials, in particular to a semi-conductive shielding material for cables with good aging resistance. Background technique [0002] The wire and cable industry is an important supporting industry for the two pillar industries of the national economy, electric power and communications, and plays an extremely important role in the national economy. The important role of energy and information transmission is the "vessel" and "nerve" of the national economy. [0003] Semi-conductive shielding material is one of the components that must be used in medium and high voltage cables. In order to adapt to the rapid development of society and the current high market demand for cross-linked cables, higher requirements are put forward for the quality and various properties of semi-conductive shielding materials. , the existing semi-conductive shielding materials are increasingly unable to meet the n...
