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 chemical-resistant polyurethane elastomer and polyvinyl chloride composite cable material. The material is prepared from raw material in parts by weight as follows: 60-65 parts of thermoplastic polyurethane elastomers, 35-40 parts of polyvinyl chloride, 0.1-0.12 parts of stearic acid, 5-6 parts of calcium benzoate, 0.8-1 part of a methyl tin mercaptide heat stabilizer, 0.2-0.3 parts of a titanate coupling 131, 19-20 parts of epoxidized soybean oil, 1-2 parts of dibenzothiazyl disulfide, 1-1.5 parts of hydroxyl silicone oil, 2-3 parts of quaternary ammonium salt montmorillonite, 5-6 parts of nano silica, 3-4 parts of a silane coupling agent KH550, a proper amount of toluene and a proper amount of deionized water. the cable material has excellent chemical resistance, can resist corrosion of salt, oil, aldehyde, ether, alkyne, strong acid, strong base and other substances, has good mechanical performance, wear resistance, aging resistance and the like, is long in service life and has higher popularization and application value.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a chemical-resistant polyurethane elastomer and polyvinyl chloride composite cable material. 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. Ther...
