Abstract

The invention discloses a low-temperature-resistant PVC cable material formula. The low-temperature-resistant PVC cable material is composed of following raw materials including, by weight, 30-40 parts of PVC resin, 10-15 parts of ultralow density polyethylene, 3-8 parts of beta-nucleating agents, 3-6 parts of polyolefin thermoplastic elastomers, 3-6 parts of octene-ethylene copolymer, 5-8 parts of poly(propylene glutarate), 3-7 parts of POE elastomer flexibilizers, 1-3 parts of antioxidants, 2-5 parts of silicon carbide fibers, 1-3 parts of nano-barium sulfate, 2-4 parts of silver loaded zeolite, 2-5 parts of glass fibers, 4-10 parts of nanometer titania, 5-10 parts of magnesium hydroxide, 1-3 parts of flexibilizers, 3-6 parts of paraffin, 3-5 parts of silane coupling agents and 1-4 parts of plasticisers. The PVC resin is used as the main component, and the ultralow density polyethylene, the beta-nucleating agents, the poly(propylene glutarate) and the POE elastomer flexibilizers are added for composite treatment, so that the low temperature resistance of PVC cables is improved, and the PVC cables are good in gloss.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a low-temperature-resistant PVC cable material formula. Background technique [0002] Wires and cables include bare wires, wires and cables for electrical equipment, power cables, communication cables and optical cables, and winding wires. Cable materials are commonly known as plastics for wire and cable insulation and sheathing. The polymer materials used mainly include polyvinyl chloride, polyethylene, Polypropylene, fluoroplastics, chlorinated polyether and polyamide, etc. These polymer materials have the characteristics of light weight, chemical corrosion resistance, easy processing and molding, excellent electrical insulation performance, and excellent mechanical and fatigue resistance properties. [0003] However, many existing cables will break when installed or used in a very low temperature environment, resulting in damage to the cable and failure to supply power...
