Wear-resistant oil-resistant flame-retardant polyvinyl chloride wire and cable material and preparation method thereof

Abstract

The invention relates to the field of a polyvinyl chloride material used for making wire and cable and discloses a wear-resistant oil-resistant flame-retardant polyvinyl chloride wire and cable material. The formula of the material provided by the invention contains the following ingredients, by weight, 100 parts of polyvinyl chloride (PVC), 55-75 parts of one or more substances selected from trimellitate, polyester and an epoxy plasticizer, 5-10 parts of one or more substances selected from a compound stabilizer and an epoxy compound, 30-50 parts of one or more substances selected from antimonous oxide, magnesium hydroxide, a composite flame retardant and calcium carbonate, 10-35 parts of one or more substances selected from ethylene chloride and nitrile rubber, 0.5-0.8 part of one or more substances selected from stearic acid, polyethylene wax and a composite lubricant and 1-2 parts of color masterbatch. The wire and cable prepared by the technical scheme can have effects of wear resistance, oil resistance and flame retardation.

Description

technical field

[0001] The invention relates to the field of polyvinyl chloride materials used for making wires and cables, in particular to a wear-resistant, oil-resistant and flame-retardant polyvinyl chloride wire and cable material and a preparation method thereof. Background technique

[0002] Polyvinyl chloride is an excellent wire and cable insulation sheath material, light weight, translucent, shiny, not easily corroded by acid and alkali, good mechanical properties, excellent dielectric properties, and low price, so in The wire and cable industry has always occupied an important share. However, since the polyvinyl chloride used in the wire and cable industry is soft polyvinyl chloride, the degree of polymerization cannot be too high, and because it is relatively hard, it needs to be softened in order to meet the needs of wire and cable, and in order to meet the requirements of heat resistance, low temperature resistance, For properties such as migration resistance ...
