Abstract

The invention discloses a nano-wollastonite powder modified ethylene propylene diene copolymer cable material, which is prepared FROM the following raw materials in parts by weight: 100-120 parts of Lanxess Deutschland ethylene propylene diene copolymer 3950, 20-30 parts of butyl rubber BBK232, 10-15 parts of SG-3 PVC (polyvinyl chloride) resin, 10-15 parts of trioctyl trimellitate, 2-5 parts of propanediol sebacate polyester, 2-5 parts of epoxidized soybean oil, 5-10 parts of polyethylene wax, 0.2-0.5 part of bisphenol A, 1-2 parts of zinc stearate, 0.5-1 part of lead sulfate tribasic, 1-2 parts of sulphur, 3-5 parts of zinc oxide, 30-40 parts of wollastonite powder, and the like. The cable material not only has excellent flame retardance and incombustibility, but also has the advantages of good high and low temperature resistance, corrosion resistance, water resistance, wear resistance, ozone resistance, ageing resistance and the like at the same time, and is durable in use.

Description

technical field

[0001] The invention relates to the field of cable materials, in particular to an EPDM cable material modified by nano wollastonite powder. Background technique

[0002] Since the advent of EPDM in 1962, due to its excellent ozone resistance, weather aging resistance and heat aging resistance, as well as good electrical insulation, heat deformation resistance and chemical corrosion resistance, the relative density It is small and has a large filling volume, which is valued by the cable industry. At present, it has replaced traditional styrene-butadiene, natural, and butyl rubber, and is widely used in low- and medium-voltage cables for marine and mobile use. But like most hydrocarbon polymers, EPDM rubber is also very flammable, and the oxygen index of pure rubber is only about 19. Therefore, the development and development of flame-retardant EPDM cable materials has been valued by the cable industry. Contents of the invention
