Abstract
The invention discloses a semiconducting shielding material for a high-strength cable, and relates to the technical field of a cable shielding material. The semi-conducting shielding material is mainly prepared from silicon rubber, chlorinated butyl rubber, conductive carbon black, brucite fibers, iron oxide powder, dicumyl peroxide, an anti-aging agent 264, an anti-aging agent RD, elaterite, boron carbide, quartz fibers, polyester pulp, chlorcosane, tri(2-chloroethyl)phosphate and cashew nut shell oil. The semiconducting shielding material for the cable, which is disclosed by the invention, uses the silicon rubber and the chlorinated butyl rubber as main raw materials; the chlorinated butyl rubber has good comprehensive performance; the silicon rubber also makes up the defect of the chlorinated butyl rubber in the aspect of cold resistance while reinforcing ozone resistance of the chlorinated butyl rubber; the semiconducting shielding material prepared by matching of the silicon rubber and the chlorinated butyl rubber is excellent in comprehensive performance; ingredients of the quartz fibers, the polyester pulp, the boron carbide and the like further improve strength and wear resistance of the product, so that the service life of the product is prolonged.
Description
Technical field
The present invention relates to cable shield field of material technology, more specifically a kind of high intensity electricity
Cable semi-conductive shielding material.
Background technology
Wires and cables industry is electric power and the important supporting of two big pillar industries in national economy that communicate
Industry, has extremely important status in national economy, and wherein industry production total amount accounts for entirely
The 4 ‰ to 5 ‰ of the total GDP of state, electric wire product plays the conveying energy, the weight of transmission information
Act on, be national economy " blood vessel " and " neural ".
Semi-conductive shielding material is one of the component that must use of medium and high voltage cable, for adapting to the fast of society
Speed development and the highest crosslinked cable market demand, the quality to semi-conductive shielding material
Having higher requirement with various performances, existing semi-conductive shielding material increasingly can not be expired
The demand of foot society.
Summary of the invention
The invention aims to make up the deficiencies in the prior art, it is provided that a kind of high-strength cable
Use semi-conductive shielding material.
It is an object of the invention to be achieved through the following technical solutions:
A kind of high-strength cable semi-conductive shielding material, is made up of following raw material: silicon
Rubber 50-70, chlorinated scoline 30-40, conductive black 35-45, brucite fiber 3-5,
Croci 2-4, cumyl peroxide 4-6, antioxidant 264 3-5, anti-aging agent RD 3-5,
Rubrax 6-8, boron carbide 3-5, quartz fibre 4-6, terylene pulp 1-3, chlorinated paraffin
6-8, trichloroethyl phosphate 1-3, cashew shell oil 7-9.
A kind of preparation method of high-strength cable semi-conductive shielding material, it is characterised in that: by
Following steps are made:
(1) each raw material is weighed by weight:
(2) by silicone rubber, chlorinated scoline, conductive black, brucite fiber, oxidation
