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

Abstract

The invention discloses a cable material with impact performance enhanced by methyl methacrylate copolymer. The 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 thio methyl tin thermal stabilizer, 0.2-0.3 part of titanate coupling agent 131, 19-20 parts of epoxy soybean oil, 2-3 parts of molybdenum disulfide, 3-4 parts of polysiloxane emulsion, 0.1-0.2 part of sodium dodecyl benzene sulfonate, 0.08-0.1 part of nonyl phenol polyoxyethylene ether, 3-4 parts of methyl methacrylate, 9-10 parts of butyl acrylate, 0.1-0.12 part of ammonium persulfate and a proper amount of water. The cable material solves the problem that existing cable materials are low in impact resistance and tenacity and has high heat resistance and size stability, and a process is convenient for industrial mass production and can be widely used in the field of cable material processing.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a cable material in which a methyl methacrylate copolymer enhances impact performance. 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 properties. Thermoplas...
