Embodiment Construction

[0040] Nitrile-PVC composite elastomer insulating material for wire and cable, wherein the components and their parts by weight are: 100 parts of nitrile rubber

[0041] 30 parts of PVC resin

[0042] Accelerator TMTD 3 parts

[0043] Accelerator DM 1 part

[0044] Antiaging agent D 2 parts

[0045] Anti-aging agent MB 2 parts

[0046] 6 parts paraffin

[0047] Zinc oxide 10 parts

[0048] 1.2 parts of stearic acid

Abstract

The invention discloses a butyronitrile-PVC (polyvinyl chloride) compound elastomer insulation material for wires and cables and a preparation method of the butyronitrile-PVC compound elastomer insulation material. The butyronitrile-PVC compound elastomer insulation material comprises, by weight, 100-120 parts of butyronitrile rubber, 30-40 parts of PVC resin, 2-3 parts of accelerant TMTD, 1-2 parts of accelerant DM, 1-2 parts of antiager, 2-3 parts of antiager MB, 6-8 parts of paraffin, 8-12 parts of zinc oxides, 1-1.5 parts of stearic acid, 10-15 parts of DOP (dioctyl-phthalate), 2-4 parts of gas-mixed carbon black, 30-40 parts of precipitated white carbon black and 50-60 parts of modified nano calcium carbonate. The insulation material produced has the advantages of good mechanical and physical performance, insulation performance, good high and low temperature resistance, oil resistance, solvent resistance, wear resistance, ozone resistance, ageing resistance and the like, is long-lasting, durable, environment-friendly, pollution-free and capable of meeting the requirements of modern wires and cables completely.

Description

technical field [0001] The invention relates to an insulating material for wires and cables, in particular to a nitrile-PVC composite elastomer insulating 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 insulating materials directly affects the quality, processing efficiency and application range of wires and cables. 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 insulation materials also have disadvantages such as poor acid and alkali resistance, heat oil...
