Anti-abrasion ultraviolet-resistant polypropylene cable material

Abstract

The invention discloses an anti-abrasion ultraviolet-resistant polypropylene cable material. The anti-abrasion ultraviolet-resistant polypropylene cable material is characterized by comprising, by weight, 40 parts of metallocene linear polyethylene, 22 parts of atactic polypropylene, 38 parts of polyvinyl chloride, 0.1-0.8 part of antioxygen, 5-15 parts of stabilizer, 20-50 parts of high-temperature plasticizer, 10-30 parts of filler, 0.1-0.5 part of UV absorbent, 0-0.1 part of 4,4-bis(6-mercaptophenyl) sulfide, 1-10 parts of calcium stearate, 1-10 pars of zinc stearate, 1-10 parts of lubricating agent, 1-10 parts of anti-abrasion powder, 1-10 parts of antimonous oxide and 5-20 parts of nano active light calcium carbonate. According to the anti-abrasion ultraviolet-resistant polypropylene cable material, the production formula and additives are improved, and thus a cable sheath and a core wire are made to have high abrasion resistance, high impact resistance and high cold resistance; the anti-abrasion powder and the high-temperature plasticizer are fused, so that the hardness and surface density of a cable are improved, and thus the anti-friction effect is achieved. The UV absorbent UV531 is added and the synergistic effect is achieved through the 4,4-bis(6-mercaptophenyl) sulfide and the UV531, in this way, ultraviolet light with the wavelength being 270-330 nm can be greatly absorbed, and the ultraviolet resistance is high.

Description

technical field [0001] The invention relates to the technical field of cable processing, in particular to a wear-resistant and anti-ultraviolet polypropylene cable material. Background technique [0002] Special resins for wire and cable include cable insulation materials and cable sheath materials, and the raw materials used are mainly polyethylene and polyvinyl chloride. At present, domestic power cables above 6kV have all used polyethylene cross-linked insulating materials; low-voltage cables below 1kV are mainly made of polyvinyl chloride insulation and polyvinyl chloride sheath, but due to the low stability and electrical insulation of polyvinyl chloride Poor, therefore, is being replaced by polyethylene more and more; communication cables generally use high-density polyethylene as the insulating layer, and linear low-density polyethylene as the sheath layer; optical cables are mainly made of high-density polyethylene and medium-density polyethylene. Polyethylene i...

Problems solved by technology

[0003] However, in the process of using cables, they are often erected in the air for power transmission, so that the cables in the air are often eroded by ultraviolet rays, causing premature cracking of the cables, affecting the cable transmission of the cables, and making people's Normal life is affected, which greatly shortens the service life of the cable, and some special industries need to be used on heavy machinery, and need to move continuously with the equipment, and constantly contact with the ground, walls and other objects. Conventional cables cannot meet its wear resistance requirements.
