Abstract

The invention discloses an anti-fatigue PVC (polyvinyl chloride) cable jacket material and a preparation method thereof. The anti-fatigue PVC cable jacket material is prepared from the following raw materials in parts by weight: 42-56 parts of SG-4 type polyvinyl chloride, 24-38 parts of polyhydroxyethyl methylacrylate, 16-24 parts of acrylic rubber, 11-17 parts of vulcanic ash, 10-15 parts of polypropylene glycol adipate, 2-3 parts of calcium stearate, 2-3 parts of barium stearate, 3-5 parts of pentaerythritol ester monooleate, 2.5-4.5 parts of hexadecyl palmitate, 10-15 parts of magnesia, 5-10 parts of carbon nanofiber, 13-19 parts of diethylene glycol dibenzoate, 10-15 parts of calcium hypophosphite, 2-4 parts of hydrogenated terphenyl, 3-5 parts of dimethylpropane carboxylic ether, 6-12 parts of hexamethylphosphoric triamide, 1.5-2.5 parts of 1,1-di(4-hydroxyphenyl)cyclohexane and 15-20 parts of a flame retardant. The cable jacket material disclosed by the invention is good in fatigue resistance, cannot generate cracks and ruptures after 50-100 thousands of times of repeated bending, has characteristics of excellent heat resistance, ageing resistance, chemical corrosion resistance, wear resistance and the like, and is long in service life and wide in application range.

Description

technical field [0001] The invention relates to an anti-fatigue PVC cable sheath material and a preparation method thereof, belonging to the field of cable materials. Background technique [0002] PVC cable material is based on polyvinyl chloride, adding stabilizers, plasticizers, inorganic fillers, additives, lubricants and other additives, and is prepared by mixing, kneading and extrusion. As a traditional cable material, it has the advantages of excellent flame retardancy, electrical insulation, wear resistance, good mechanical properties, wide range of sources, and low price, and occupies the most important market share in the domestic market. At present, with the continuous expansion of wire and cable market demand and the continuous deepening of my country's PVC research and development work, the performance requirements for PVC cable materials are becoming more and more stringent. Existing PVC cable materials on the market have the disadvantage of poor fatigue re...
