Abstract

The invention discloses a multi-polymer modified PVC (polyvinyl chloride) cable material which is prepared from raw materials in parts by weight as follows: 13-15 parts of carbon nano tubes, 13-14 parts of neopentyl glycol diacrylate, 10-12 parts of dimethyl terephthalate, 0.02-0.04 parts of tert-butyl peroxy pivalate, 5-7 parts of titanium dioxide, 1-1.5 parts of sodium polymethacrylate, 68-72 parts of PVC, 7-9 parts of a polyurethane prepolymer, 3-5 parts of cellulose acetate, 2-3 parts of microcrystalline wax and 7-9 parts of an auxiliary. The polymers such as the polyurethane prepolymer, sodium polymethacrylate and the like are added to the PVC cable material with a special process, the carbon nano tubes are further added according to the formula, so that the composite material has good strength, elasticity, fatigue resistance, wear resistance and flexibility, the thermal stability of the product is enhanced by the aid of the auxiliary, the processability is good, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to polyvinyl chloride cable materials modified by various polymers and a preparation method thereof. Background technique [0002] Insulating materials for cables are generally required to have excellent long-term heat aging resistance, radiation resistance, stable electrical properties, flame retardancy and excellent insulation properties. Polyvinyl chloride is usually used as the sheath layer of wires and cables. It is insoluble in common solvents at room temperature, has low water absorption, and has excellent electrical insulation properties. However, ordinary PVC cable sheath materials generally have problems such as large shrinkage rate and insufficient surface hardness, which are prone to wear and poor wear resistance. [0003] The present invention aims at the problems of the above-mentioned polyvinyl chloride cable material, through a special process, polymers such as polyur...
