Pottery clay modified cable material and preparation method thereof

Abstract

The invention provides a pottery clay modified cable material. The pottery clay modified cable material is prepared from the following raw materials in parts by weight: 100 to 120 parts of Germany Lanxess EPDM rubber 3950, 20 to 30 parts of nitrile rubber N41, 10 to 15 parts of chlorosulfonated polyethylene rubber CSM2305, 10 to 15 parts of diisodecyl phthalate, 2 to 5 parts of epoxidized triglyceride, 2 to 5 parts of triethyl citrate, 5 to 8 parts of chlorinated paraffin, 0.5 to 1.0 part of stearic acid, 2 to 3 parts of calcium stearate, 1 to 2 parts of sulfur, 3 to 5 parts of zinc oxide, 30 to 40 parts of calcined pottery clay, 20 to 30 parts of precipitated white carbon black, 5 to 15 parts of carbon black N660, 3 to 5 parts of zinc borate, 1 to 2 parts of an aluminate coupling agent DL- 411, 0.1 to 1 part of an ultraviolet screening agent UV-531, 1 to 2 parts of a crosslinking agent TAIC, 1 to 2 parts of 3-aminopropyl trimethoxysilane, 1 to 2 parts of an anti-aging agent OD, 1 to 2 parts of an anti-aging agent ODA, 1 to 2 parts of an anti-aging agent TPPD, 1 to 2 parts of an accelerator Na-22, 3 to 4 parts of an accelerator DM and 2 to 3 parts of aluminum hydroxide.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a clay modified cable material. 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 [0003] The object of the present invention is to provi...
