Description

technical field [0001] The invention relates to the field of cable materials, in particular to a corrosion-resistant cable material and a preparation method thereof. Background technique [0002] With the rapid growth of wire and cable applications and rapid economic development, people's requirements for the performance of cable materials are constantly improving, especially in the communication industry, and the weak current industry has higher requirements for the comprehensive performance of cables. Cable materials not only need to have good insulation, but also need to have good corrosion resistance, environmental protection and flame retardancy. [0003] Chinese patent CN10507616A discloses a high thermal conductivity polyvinyl chloride sheath material and cable for graphene-containing cable materials. The sheath material of the present invention includes the following mass fraction materials: 100 parts of polyvinyl chloride, 0.05-3 parts of heat conducting agent, auxi...

Problems solved by technology

37-53 parts of filler, the cable sheath layer of the present invention is composed of polyvinyl chloride resin, heat conduction agent, auxiliary heat conduction agent, plasticizer, antioxidant, stabilizer, lubricant, filler, flame retardant and The combined use of pigments can significantly improve the thermal conductivity and corrosion resistance of the sheath layer material, but the heat conduction agent in this invention uses graphene or graphene oxide as the conductive material, which may affect the insulation performance of the sheath material and pose a safety hazard

[0004] Chinese patent CN105837911B discloses a corrosion-resistant polyvinyl chloride cable material. The raw material is composed of the following components by weight: SG3 zinc polyvinyl chloride resin: 100 parts, plasticizer 1:30 parts, plasticizer 2:3 Parts, 12 parts of nano-calcium carbonate, commercially available calcium-zinc stabilizer: 12 parts, polyethylene wax: 1.2 parts, ACR impact modifier: 3 parts, bisphenol A: 0.2 parts, nano-barium sulfate 2 parts, silicone 0.6 parts of powder, Haloxylon silicone powder is nano-silica powder coated with silicone, the plasticizer 1 is trioctyl trimellitate, and the plasticizer 2 is epoxy resin. Soybean oil or dioctyl terephthalate, the cable material has good processing performance, and significantly improves the wear resistance of the product, and at the same time enhances the corrosion resistance of the material, but the thermal stability of polyvinyl chloride resin is relatively poor, burning When the smoke density is high, the amount of smoke is large, which is very harmful to the environment
