Waterproof and antibacterial PVC (polyvinyl chloride) cable material formula

Abstract

The invention discloses a waterproof and antibacterial PVC (polyvinyl chloride) cable material formula. The formula comprises raw materials in parts by weight as follows: 30-40 parts of PVC resin, 10-15 parts of EPDM (ethylene-propylene-diene monomer) rubber, 5-10 parts of chloroprene rubber, 2-5 parts of nano barium sulfate, 1-5 parts of nano titanium dioxide, 2-6 parts of carbon nanotubes, 5-10 parts of expanded perlite, 3-8 parts of inorganic silver-ion-containing silicate, 2-3 parts of an antioxidant, 1-4 parts of sodium hexametaphosphate, 2-5 parts of microcrystalline cellulose, 1-2 parts of silver-loaded zeolite, 2-5 parts of elastic fiber, 4-10 parts of aluminum oxide, 5-10 parts of magnesium hydroxide, 1-3 parts of an anti-aging agent, 3-6 parts of paraffin, 3-5 parts of a silane coupling agent and 1-4 parts of a plasticizer. PVC resin, EPDM rubber and chloroprene rubber are subjected to blending crosslinking modification, so that the cable material has characteristics of plastic and rubber, has high strength, high elongation, long service life, light weight, good bonding property and excellent waterproof performance, has aging resistance and flame retardance and is convenient to construct and maintain. Raw materials are non-toxic and harmless, environment-friendly and harmless to body health.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a waterproof and antibacterial 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.
