Abstract

The invention belongs to the technical field of cable insulation materials, and particularly relates to a polyvinyl chloride composite cable insulation material which comprises 100 parts of polyvinylchloride resin, 15-25 parts of plasticizer, 5-20 parts of filler, 5-10 parts of environment-friendly stabilizer, 4-8 parts of environment-friendly flame retardant, 1-3 parts of silicone master batch and 4-8 parts of pre-crosslinking modifier P95. According to the polyvinyl chloride composite cable insulating material provided by the invention, through the interaction of the components, the appearance of the material is smoother and finer, and the surface friction coefficient of the material is reduced, so that the surface gloss of the material is improved, the surface defects are eliminated, and the wear resistance and scratch resistance of the polyvinyl chloride composite cable insulating material are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of cable insulating materials, and in particular relates to a polyvinyl chloride composite cable insulating material and a preparation method and application thereof. Background technique [0002] With the development of the modern automobile industry, the structure is getting tighter and tighter, and the safety requirements are put in the first place. The requirements for the insulating materials of the wire and cable used in the car are getting higher and higher. Due to the special location of the wires and cables used in automobiles, it is inevitable that the ground wire and the wire will rub against each other during the operation of the car. Once the plastic insulation protective sleeve of the wire and cable is worn out, it will directly lead to a short circuit and cause traffic accidents. Therefore, not only must meet the necessary properties of flame retardancy, high temperature and low temperature re...
