Problems solved by technology

Although the thermoplastic polyurethane elastomer improves the toughness of the polyvinyl chloride material, it also reduces the modulus of the composite material at the same time, and uses dioctyl phthalate as a plasticizer, and the benzene ring structure contained in it is harmful to the human body. Potentially physiologically toxic and cause environmental pollution

Embodiment Construction

[0014] A composite cable material with polypyrrole-coated composite filler to improve thermal conductivity, prepared from the following raw materials in parts by weight (kg): thermoplastic polyurethane elastomer 60, polyvinyl chloride 35, stearic acid 0.1, calcium benzoate 5 , thiol methyl tin heat stabilizer 0.8, titanate coupling agent 1310.2, epoxy soybean oil 19, dimethyl silicone oil 2, aluminum oxide 5, carbon fiber 2, aluminum nitride 2, pyrrole 1, twelve Alkyl sodium sulfate 0.1, ammonium persulfate 0.9, nonylphenol polyoxyethylene ether 0.8, deionized water in proper amount.

[0015] The composite cable material for improving thermal conductivity of the polypyrrole-coated composite filler is made by the following specific steps:

[0016] (1) Put calcium benzoate into a high-speed mixer, heat to 100°C, add stearic acid and titanate coupling agent 131, stir at 1000 rpm for 20 minutes, and discharge for use;

[0017] (2) Add polyvinyl chloride into the high-speed mixer,...

Abstract

The invention discloses a composite cable material with the heat conductivity improved through polypyrrole coated composite filler. The composite cable material is prepared from, by weight, 60-65 parts of thermoplastic polyurethane elastomer, 35-40 parts of polyvinyl chloride, 0.1-0.12 part of stearic acid, 5-6 parts of calcium benzoate, 0.8-1 part of methyltin mercaptide heat stabilizer, 0.2-0.3 part of organic titanate coupling agent 131, 19-20 parts of epoxidized soybean oil, 2-3 parts of dimethyl silicone oil, 5-6 parts of aluminum oxide, 2-3 parts of carbon fiber, 2-3 parts of aluminum nitride, 1-1.2 parts of pyrrole, 0.1-0.11 part of lauryl sodium sulfate, 0.9-1 part of ammonium persulfate, 0.8-1 part of nonylphenol polyoxyethylene ether and a proper amount of deionized water. The prepared composite cable material of thermoplastic polyurethane elastomer and polyvinyl chloride has good mechanical performance, high tensile strength, high insulation, good heat conduction, good cooling efficiency and good processing performance and is suitable for cable circuits severe in heating.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a composite cable material in which polypyrrole-coated composite fillers improve thermal conductivity. Background technique [0002] Polyvinyl chloride (PVC) is characterized by high withstand voltage and insulation resistance, and has properties such as flame retardancy, oil resistance, weather resistance, and chemical resistance, but its dielectric constant and dielectric loss are large, and its cold resistance is poor. Plastic has the characteristics of low price, large usage, and excellent performance in all aspects. It is mainly used in insulation, semi-conductive shielding and sheathing of various wires and cables for wires and cables below 1kV and local communication cables. Thermoplastic polyurethane elastomers have the characteristics of plastic reprocessing and rubber elasticity, and are excellent in cold resistance, abrasion resistance and antibacterial propert...
