High-temperature-resistant moisture-proof mould-proof environment-friendly cable material and preparation method thereof

Abstract

The invention discloses a high-temperature-resistant moisture-proof mould-proof environment-friendly cable material and a preparation method thereof. The cable material is composed of a mixture A and a mixture B, wherein the mixture A comprises, by weight, 30-40 parts of high-density vinyl resin, 20-30 parts of polyacrylate, 25-35 parts of maleic anhydride grafted poly ethylene, 20-30 parts of methyl vinyl silicon rubber, 1-3 parts of semi-reinforcing carbon black, 40-60 parts of light calcium carbonate, 1-3 parts of N, N'-m-phenylenedimaleimide, 1.5-2.5 parts of aniline-methyl-triethoxysilane, 1-3 parts of calcium stearate, 3-4 parts of antioxidant DSTP and 10-20 parts of mica powder; the mixture B comprises, by weight, 50-70 parts of chlorinated polyethylene, 30-40 parts of poly(styrene-butadiene-styrene), 20-30 parts of ethylene-ethyl acetate copolymer, 0.3-0.5 part of poly(4-methyl-1-pentene), 1-3 parts of antiager TPPD, 2-4 parts of polyethylene wax, 5-10 parts of polycaprolactone, 2-3 parts of sodium dibutyl naphthalene sulfonate, 1-3 parts of superfine polyvinyl alcohol, 2-4 parts of isooctyl thioglycolate dimethyl tin and 10-15 parts of zinc borate. The preparation method is simple, and the cable material has excellent electric performance, good physical mechanical performance and meets requirements of temperature change of different environments.

Description

technical field [0001] The invention relates to a high-temperature-resistant, moisture-resistant, mildew-proof, and environment-friendly cable material and a preparation method thereof, belonging to the technical field of cable materials. Background technique [0002] With the rapid development of economy, wires and cables are widely used in various industries and fields. With the frequent occurrence of electrical fire accidents, the flame retardant problem of wires and cables has gradually attracted the attention of all countries in the world. A large amount of smoke and toxic and corrosive gases are released when the cable burns, which is a dangerous factor in the fire, which hinders people's safe evacuation and fire-fighting work, and causes serious loss of life and property. At the same time, with the development of the communication industry, the automobile industry and the computer industry, especially in many occasions such as aviation wires, automobile wires, high-t...
