Abstract

The invention provides a waterproof and antiflaming PVC (polyvinyl chloride) cable material and a preparation technology thereof. The waterproof and antiflaming PVC cable material comprises the following components in parts by weight: 55-65 parts of PVC of degree of polymerization of 590-720, 35-45 parts of PVC of degree of polymerization of 1110-1340, 20-30 parts of trioctyl trimellitate, 15-25 parts of didecyl phthalate,5-10 parts of environmental protection calcium and zinc compound stabilizer, 5-10 parts of compound rare earth stabilizer, 4-8 parts of antimonous oxide, 0.3-1 parts of lubricant, 0.1-0.5 parts of antioxygen, 3.5-7 parts of nano barium sulfate, 2.6-5.2 parts of calcined kaolin, 3.5-7 parts of nano silica, and 0.18-0.36 parts of silane coupling agent, wherein the silane coupling agent is vinyl (beta-methoxy-ethoxy) silane, vinyl trimethoxy silane or gamma-glycidyl ether oxygen propyl three methoxy-silane. The hydroscopicity of a cable jacket is greatly lowered, when the cable material is used in wet or soaking environment, the stable property of electric is further improved and does not change generally, and the compact of the product is improved and the micropores of the material are removed.

Description

Technical field [0001] The invention relates to a cable material, in particular to a high-insulation cable sheath material. Background technique [0002] PVC cable material is currently a common cable insulation material used in the cable industry. It has excellent mechanical properties, good electrical properties, oxidation resistance, light resistance and corrosion resistance. As PVC cable materials are widely used in high-rise buildings, electronic components, automobiles and aerospace industries, the requirements for the flame retardant properties of cable materials are also increasing. Polyvinyl chloride cable material has good mechanical and physical properties, electrical properties, simple processing technology, excellent processing performance, and low price. It has always been in the forefront of the cable material industry and has been widely used. PVC cable materials are generally used in products such as medium and low voltage, data communication cables, and general...
