Abstract

The invention provides a low-temperature-resistant PVC composite cable material which is prepared from 100 parts of EPDM composite, 18 to 20 parts of ethylene-vinyl acetate copolymer, 16 to 18 parts of nano silicon dioxide, 4 to 6 parts of a composite compatilizer, 15 parts of chlorinated polyethylene, 5 to 8.5 parts of dicumyl peroxide, 0.2 to 0.3 part of sulfur, 0.4 part of a TMTD accelerant, 3.2 to 5.5 parts of a composite vulcanizing agent, 60 to 80 parts of a filling agent, 15 to 20 parts of high polymerization degree polyvinyl chloride, 0.8 part of an anti-aging agent and 20 to 25 partsof a plasticizer, wherein the EPDM composite is prepared from 90 to 94 parts of ethylene-propylene-diene monomer and 6 to 10 parts of modified chlorosulfonated polyethylene; the composite compatilizeris prepared from a mixture of dicumyl peroxide, glycidyl methacrylate and styrene; the composite vulcanizing agent is a mixture of triallyl isocyanurate and trimethylolpropane trimethyl acrylate. According to the composite cable material disclosed by the invention, the ingredients are optimized and designed; thus, the prepared composite cable material has the advantages of better low temperatureresistance and oil resistance and more excellent mechanical property.

Description

technical field [0001] The invention relates to the field of wires and cables, in particular to a low-temperature-resistant PVC composite cable material and a preparation method thereof. Background technique [0002] Wire and cable is a wire product used to transmit electric (magnetic) energy, information and realize electromagnetic energy conversion. As the main carrier of power transmission, wires and cables are widely used in electrical equipment, lighting circuits, household appliances, etc., and their quality directly affects the quality of projects and the safety of consumers' lives and property. The current wire and cable materials include PVC, PE, PP, EPDM, etc. PVC materials have excellent mechanical and physical properties, flexibility, chemical resistance, cheap price, and excellent processing performance, but they are not resistant to oil and organic solvents. And the insulation is hard. EPDM has excellent oxidation resistance, ozone resistance and corrosion re...
