Abstract

The invention discloses a moisture-proof aging-resistant cable material. The moisture-proof aging-resistant cable material comprises the following raw materials in parts by weight: The moisture-proofaging-resistant cable material comprises the following raw materials in parts by weight: 22-36 parts of polyvinyl chloride resin, 9-16 parts of nitrile rubber, 15-20 parts of neopentyl glycol diacrylate, 4-8 parts of nano zinc oxide, 2-4 parts of glass fiber, 2-3 parts of triallyl isocyanurate, 7-9 parts of gamma-methyl allyl oxopropyl trimethoxysilane, 0.5-1 part of zinc diethyl dithiocarbamate,1-2 parts of 4-vinyl phenyl acetate, 2-9 parts of alumina borosilicate whisker, 10-15 parts of aluminium hydroxide, 3-6 parts of cellulose acetate, and 10-15 parts of an auxiliary agent. The cable material has high mechanical strength and wide adaptation temperature scope, and has the advantages of high flame retardation, fire resistance, good heat stability, aging resistance, and excellent electrical isolation performance.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a moisture-proof and aging-resistant cable material and a preparation method thereof. Background technique [0002] In recent years, it has been found that more than 80% of the fatalities in fire accidents are related to the dense smoke and toxic gases produced by materials. With the rapid development of my country's modern industry, safety and prevention measures should be more and more perfect. In many large public places, in order to avoid the secondary disaster caused by cable fire (a large amount of smoke and acid gas are produced when the cable burns), special The wires and cables used to transmit electric energy and communication signals are not only required to have flame retardant properties such as preventing flame spread when the cable and the surrounding environment are on fire, and can maintain the cable to continue to transmit electric energy and communication signals,...
