Abstract

The invention discloses a silicone-rubber cable insulating layer. The silicone-rubber cable insulating layer is mainly prepared from the following raw materials: silicone rubber, butyl rubber, magnesium oxide, an anti-aging agent, zinc borate, acetylene black, nano zinc oxide, tetrabromo bisphenol, natural rubber, an ethylene-octylene copolymer, diatomite, polyvinyl chloride, tricresyl phosphate,chlorinated paraffin, an accelerant and asbestos fibers. According to the silicone-rubber cable insulating layer disclosed by the invention, through a reasonable raw material formula, the prepared cable insulating layer material has the advantages of high corrosion resistance, good aging resistance and long service life. The preparation method is simple, and the equipment requirements are not high.

Description

technical field [0001] The invention relates to the field of cables, in particular to a silicone rubber cable insulation layer. Background technique [0002] With the development of the wire and cable industry, people put forward higher and stricter performance requirements for cable products, and pay more and more attention to functionality, safety, and service life. As one of the important components of cable products, the cable sheath material has higher and higher requirements. As we all know, external corrosive substances, high temperature or open flames have a damaging effect on traditional cable rubber sheaths, because cable rubber sheaths will lose their use value if they are affected by the above factors for a long time. The aging resistance needs to be improved urgently. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgme...
