Abstract

The invention discloses a butyronitrile-PVC (polyvinyl chloride) compound elastomer flame-retardant sheath material for wires and cables and a manufacturing method of the butyronitrile-PVC compound elastomer flame-retardant sheath material. The butyronitrile-PVC (polyvinyl chloride) compound elastomer flame-retardant sheath material is composed of, by weight, 100-120 parts of butyronitrile rubber, 40-45 parts of PVC resin, 1-2 parts of sulfur, 0.1-0.2 part of accelerant TMTD, 1-1.5 parts of accelerant CZ, 2-3 parts of antiager, 15-20 parts of antimonous oxide, 5-7 parts of zinc oxides, 1-2 parts of stearic acid, 12-14 parts of DOP (dioctyl-phthalate), 6-8 parts of DOS (dioctyl sebacate), 15-18 parts of TCP (tertiary calcium phosphate), 0.5-0.8 part of zinc stearate, 1-1.5 parts of barium stearate, 0.1-0.2 part of bisphenol A, 2-2.5 parts of butyl ester, 2.5-3 parts of carbon black master batch, 15-20 parts of modified diopside and 25-30 parts of semi-reinforced carbon black. The flame-retardant sheath material has the advantages of good mechanical and physical performance, good high and low temperature resistance, oil resistance, solvent resistance, wear resistance, ozone resistance, ageing resistance, flame retardancy, low smoke and the like and is long-lasting, durable, environment-friendly and pollution-free.

Description

technical field [0001] The invention relates to a flame-retardant sheathing material for wires and cables, in particular to a nitrile-PVC composite elastomer flame-retardant sheathing material for wires and cables and a preparation method thereof. Background technique [0002] With the continuous development of modern industries, various modern electrical facilities (such as communication facilities, elevators, audio telephones, locomotive leads, etc.) have higher and higher requirements for wires and cables. Among them, the performance of the flame retardant sheathing material directly affects the quality, processing efficiency and application range of the wire and cable. Because ordinary PVC cable materials contain a lot of chlorine, they will emit a lot of smoke when burning, which will suffocate people, affect visibility, and produce some carcinogens and HCl gas, which will cause serious harm to the environment. Ordinary PVC flame retardant sheath materials also have di...
