Flexible, cold-proof and light abrasion-resistant cable material

Abstract

The invention discloses a flexible, cold-proof and light abrasion-resistant cable material. The flexible, cold-proof and light abrasion-resistant cable material is prepared from, by weight, 60-80 parts of PVC resin powder, 20-30 parts of polyurethane elastomer, 40-50 parts of glass fibers, 5-10 parts of phosphite ester, 3.5-5.5 parts of nanometer active light calcium, 2-5 parts of polyethylene wax, 0.5-2 parts of potassium peroxodisulfate, 1-2 parts of montmorillonite, 3-5 parts of dioctyl terephthalate, 3-5 parts of epoxidized soybean oil, 0.5-1 part of silicone oil, 1-2 parts of antimonous oxide, 2-4 parts of zinc stearate, 1-5 parts of natural mica, 1-2 parts of titanium dioxide, 3-5 parts of abrasion-resistant powder and 6-8 parts of coupling agent. According to the cable material, the abrasion-resistant degree of a cable sheath and a core wire layer is increased while various physical indexes in a conventional environment are guaranteed, the polyurethane elastomer is added into PVC resin, the polyurethane elastomer has excellent abrasion resistance, low temperature resistance and oil resistance, belongs to polar polymers and can be organically combined with PVC, and the mechanical performance of the PVC cable material can be effectively improved.

Description

technical field [0001] The invention relates to the field of cable material preparation, in particular to a flexible, cold-resistant, lightweight and wear-resistant cable material. Background technique [0002] Wire and cable refers to materials used for power, communication and related transmission purposes. With the development of society, wires and cables are more and more widely used in various fields, such as transportation, communication, construction, etc. Therefore, the requirements for the professional field of wires and cables are also getting higher and higher. Traditional polyvinyl chloride cable material, the formula is: 100 parts of polyvinyl chloride, 50-60 parts of dioctyl phthalate, 6-10 parts of compound stabilizer, 1-3 parts of lubricant, 20 parts of active light calcium carbonate -30 parts, the above materials and cables can only meet the needs of conventional indoor and outdoor environments. For some special industries, they need to be used on heavy mac...

Traditional polyvinyl chloride cable material, the formula is: 100 parts of polyvinyl chloride, 50-60 parts of dioctyl phthalate, 6-10 parts of compound stabilizer, 1-3 parts of lubricant, 20 parts of active light calcium carbonate -30 parts, the above materials and cables can only meet the needs of conventional indoor and outdoor environments. For some special industries, they need to be used on heavy machinery, and need to follow the equipment to move continuously and keep in contact with the ground, walls and other objects. Conventional cables cannot meet the requirements. Its wear resistance requirements
