Abstract

The invention relates to a preparation formula of an insulation sheath of a cable. The formula comprises the following raw materials: 60-65 parts of styrene butadiene rubber, 9-10 parts of zinc oxide,2-4 parts of an antioxidant, 8-15 parts of a plasticizer, 8 parts of an antioxidant and 115-1135 parts of a filler, wherein the antioxidant is 4-[methyl-beta-(3,5-ditert-butyl-4-hydroxyphenyl)propionate] pentaerythritol ester; the plasticizer is a mixture of 52 DEG chlorinated paraffin and dioctyl phthalate; the antioxidant is N-isopropyl-p-phenylene diamine; and the filler is a mixture of a talcum powder and calcium carbonate. The insulation sheath for the cable has the characteristic of good ageing resistance.

Description

technical field [0001] The invention relates to a formula for preparing insulation skins for electric cables. Background technique [0002] Due to its unique mechanical and physical properties, rubber sheathed cables are used in many fields of products, so there are many categories, such as: general-purpose, welding machine, electric power, marine, mining, wind energy, nuclear energy, etc. However, due to the influence of external factors and internal current during the application of the cable, the aging of the insulation skin is inevitable. Contents of the invention [0003] The object of the present invention is to solve the above deficiencies in the prior art, and to provide a formula for preparing insulating skins for cables, and the insulating skins have the characteristics of strong aging resistance. [0004] The present invention is a kind of insulation skin preparation formula for electric cable, it is characterized in that, by weight, its raw material compositio...
