Electric special purpose oil-proof composite cable

Abstract

The invention discloses an electric special purpose oil-proof composite cable. The electric special purpose oil-proof composite cable is prepared from 4-8 parts by weight of basalt fibers, 2-7 parts by weight of calcium carbonate, 7-12 parts by weight of nitrile silicone rubber, 6-10 parts by weight of chlorinated polyethylene rubber, 5-9 parts by weight of a modifier, 8-15 parts by weight of EPDMrubber, 2-6 parts by weight of a polyolefin elastomer, 5-9 parts by weight of paraffinic hydrocarbon oil, 10-15 parts by weight of calcined kaolin, 0.3-0.7 parts by weight of zinc oxide, 0.5-1 part by weight of polydimethylsiloxane, 0.2-0.5 parts by weight of iron oxide, 0.5-0.9 parts by weight of calcium sulfate, 7-15 parts by weight of natural rubber, 10-20 parts by weight of polyvinyl chloride resin, 3-8 parts by weight of a coupling agent, 7-12 parts by weight of EPDM rubber, 0.5-1 part by weight of magnesium oxide, 6-10 parts by weight of organic bentonite, 4-7 parts by weight of whitecarbon black, 4-8 parts by weight of a modified XH-7 molecular sieve, 0.4-0.8 parts by weight of calcium carbonate, 0.3-0.7 parts by weight of a coupling agent vinyl triethoxysilane, 2-5 parts by weight of a red phosphorus flame retardant synergist and 10-18 parts by weight of phenolic resin. The composite rubber for cable materials is a non-polar polymer, has the characteristics of elasticity, softness and abrasion resistance, and does not obviously harden and lose softening and elasticity along with continuous ambient temperature decreasing.

Description

technical field [0001] The invention relates to the technical field of cable-related materials, in particular to an oil-proof composite cable for electrical use. Background technique [0002] With the rapid development of the national economic plan, the electricity consumption of urban residents has also risen rapidly. The insulation layer of wires and cables made of traditional polymer materials is burned and damaged due to excessive heat generated by high-load electricity or short-circuit. Normal life power supply cannot be guaranteed, and it is more likely to cause a fire. For example, heat-resistant 90-degree coke-linked polyethylene and polyvinyl chloride are usually not heat-resistant; ordinary polyvinyl chloride materials with an insulation degree of 0.6-110 will easily break down the insulating material after the carrying current exceeds the carrying current, and it is easy to short-circuit electronic equipment; at the same time, these polymer materials It is easy t...

[0002] With the rapid development of the national economic plan, the electricity consumption of urban residents has also risen rapidly. The insulation layer of wires and cables made of traditional polymer materials is burned and damaged due to excessive heat generated by high-load electricity or short-circuit. Normal life power supply cannot be guaranteed, and it is more likely to cause a fire

For example, heat-resistant 90-degree coke-linked polyethylene and polyvinyl chloride are usually not heat-resistant; ordinary polyvinyl chloride materials with an insulation degree of 0.6-110 will easily break down the insulating material after the carrying current exceeds the carrying current, and it is easy to short-circuit electronic equipment; at the same time, these polymer materials It is easy to be ignited when encountering an open flame, releasing toxic gas and polluting the air
