Problems solved by technology

[0002] At present, the most used insulation and sheath materials in my country's cable industry are polyvinyl chloride plastics and natural rubber, styrene-butadiene rubber, neoprene, ethylene-propylene rubber and other vulcanized elastomers. PVC contains Cl -1 , the stabilizer used has Sn +2 .Pb +2 .Cb +2 .Cr +2 and other harmful ions, cable products will react slowly during use, releasing HCL harmful gas and polluting the environment
Rubber vulcanization aids include toxic substances such as sulfur, thiazole, thiuram, and thiourea. Most of the by-products generated by the reaction contain toxic substances. The steam vulcanization process is used in the production of cables, and flue gas and waste residues are generated by the combustion of boiler fuel. emissions, causing serious pollution to the environment, and it is operated at high temperature and high pressure, and the operation process is complex and dangerous
Another defect of the vulcanization process is that the sulfur corrodes the copper wires and makes the wires dirty and black, which affects the quality and reduces the service life.

Abstract

The thermoplastic elastomer is used in environment-protecting cable sheath. It consists of at least thermoplastic polyurethane elastomer, styrene-butadidne-methyl methacrylate copolymer, modifier, plasticizer and stuffing. It is acid resistant, alkali resistant, low temperature resistant and light and the cable and wire produced with the said elastomer has less compression deformation, high flex resistance, high oil resistance and high resilience. The elastomer may be also used in sealing stripe for automobile, tractor, door and window, various hose and other mechanical parts.

Description

technical field [0001] The invention relates to a thermoplastic elastomer and a production method, which are especially suitable for insulation and sheath materials of cables, and belong to the technical field of plastic or rubber materials. technical background [0002] At present, the most used insulation and sheath materials in my country's cable industry are polyvinyl chloride plastics and natural rubber, styrene-butadiene rubber, neoprene, ethylene-propylene rubber and other vulcanized elastomers. PVC contains Cl -1 , the stabilizer used has Sn +2 .Pb +2 .Cb +2 .Cr +2 Such as harmful ions, cable products will react slowly during use, release HCL harmful gas, and pollute the environment. Rubber vulcanization aids include toxic substances such as sulfur, thiazole, thiuram, and thiourea. Most of the by-products generated by the reaction contain toxic substances.
