Abstract

The present invention discloses an electric cable insulation material, which comprises, by weight, 60-80% of fluorinated ethylene propylene, 10-12% of a butyl rubber, 10-12% of an ethylene propylene diene monomer, 1-2% of a self-adhesive butyl semi-conductive tape, 5-10% of an organic solvent, 2-3% of a fluorine-containing diacyl peroxide, 2-3% of polyphenylene sulfide, 2-3% of polytetrafluoroethylene powder, and 1-2% of alkali-free glass fiber. The prepared electric cable insulation material provides more excellent temperature tolerance, insulation property and flame resistance compared with other existing electric wire and electric cable materials, and can be widely used in petroleum, chemical engineering, medicine and other corrosive chemical industries.

Description

technical field [0001] The invention belongs to the field of new material processing, in particular to a production method of cable insulation materials. Background technique [0002] A common cable consists of a conductor and a layer of insulating material covering the surface of the conductor. [0003] The cable is composed of several conductor cores twisted into a cable. The gaps between the conductor cores are filled with asbestos ropes. The outer layer is tied tightly with a tape and then wrapped with a sheath. The diameter of each wire is 0.08mm, and the insulating layer material is a new type of material mixture. [0004] Most of the cable insulation materials are polyvinyl chloride and polyethylene. There are also many other insulating materials with special requirements, such as: halogen-free low-smoke polyolefin, fluoroplastic, silicone rubber, nitrile, ethylene-propylene rubber, nylon and other materials. [0005] At present, the domestic cable insulation mater...
