Abstract

The invention discloses a modified pseudo-boehmite butadiene-acrylonitrile rubber compound cable material and a preparation method thereof. The modified pseudo-boehmite butadiene-acrylonitrile rubber compound cable material is prepared from the following raw materials in parts by weight: 50 to 60 parts of acrylonitrile rubber, 30 to 35 parts of pseudo-boehmite, 20 to 30 parts of thermoplastic polyurethane elastomer, 30 to 40 parts of poly(isobutylene-co-p-methyl-styrene-co-p-bromomethylstyrene), 10 to 12 parts of neopentyl glycol dibenzoate, 6 to 8 parts of calcium stearate, 30 to 40 parts of 2-ethylhexyl diphenyl phosphate, 3 to 5 parts of zinc oxide, 6 to 8 parts of chloropropyl triethoxy silane, 4 to 6 parts of polyterpene phenolic resin, and the like. According to the modified pseudo-boehmite butadiene-acrylonitrile rubber compound cable material and the preparation method thereof provided by the invention, the modified pseudo-boehmite butadiene-acrylonitrile rubber is used, so that the volume resistivity of the acrylonitrile rubber is increased, and an electrical insulation property of the acrylonitrile rubber is improved; and the pseudo-boehmite treated by the chloropropyl triethoxy silane, the epoxidized methyl acetorieinoleate and the 2-ethylhexyl diphenyl phosphate is used as a filler, so that a mechanical property of the product is improved, the surface states of pseudo-boehmite particles can be well improved, the compatibility of the pseudo-boehmite particles and the acrylonitrile rubber is improved, and the ageing resistance of the acrylonitrile rubber material can be remarkably improved.

Description

technical field [0001] The invention relates to a cable material, in particular to a modified pseudo-boehmite nitrile rubber composite cable material and a preparation method thereof. Background technique [0002] With the development of my country's electric power industry and communication industry, the demand for insulating cable materials with excellent performance is also increasing. Cable material is a general term for plastics used for wire and cable insulation and sheathing. It is made of rubber, plastic, nylon and other materials as base materials, combined with auxiliary components such as plasticizers, fillers, color masterbatches, and antioxidants. Different types of cables and The use environment has different requirements on the performance of cable materials. Most of the commercially available cable materials are not resistant to scratches and folds, are easy to corrode and oxidize the internal metal wires, have poor flame retardancy, cannot balance hardness a...
