Abstract

The invention discloses a PVC (polyvinyl chloride) cable material which comprises, by weight, 55-65 parts of SG-2PVC resin, 30-45 parts of SG-4PVC resin, 12-15 parts of trioctyl trimellate, 2-3 parts of calcium-zinc stabilizer, 1-2 parts of linseed oil, 1-2 parts of chlorinated paraffin, 7-11 parts of magnesium hydroxide, 5-8 parts of antimonous oxide, 2-4 parts of calcium stearate and 25-30 parts of inorganic filler. The PVC cable material has excellent mechanical performance, excellent flame retardance and cold resistance and high comprehensive performance and is completely supportive of being used in some places with high requirements.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a PVC cable material. Background technique [0002] PVC cable material is a kind of plastic particle obtained by mixing and granulating polyvinyl chloride resin as the main body, adding various additives and fillers. It is mainly used for the outer layer of wire and cable, and has good mechanical properties and electrical insulation properties. [0003] At present, there are many kinds of PVC cable materials on the market, but most of these existing cable materials have poor mechanical properties or flame resistance, and can only be used in some ordinary occasions, and cannot be used in some demanding occasions. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a PVC cable material with excellent mechanical properties, flame retardancy and cold resistance. [0005] In order to solve the above technical problems, the p...
