The invention discloses a semi-conductive shielding material for high voltage grade power cables, and belongs to the field of semi-conductive shielding materials. The semi-conductive shielding material comprises, by weight, 100 parts of a base material, 45-48 parts of conductive carbon black, 3-5 parts of a stripping agent, 5-8 parts of an anti-oxidation/metal deactivator, 4-6 parts of a cross-linking agent, 3-5 parts of a reinforcing agent, 0.5-1 part of an antioxidant and 10-12 parts of a plasticizer. The semi-conductive shielding material with excellent mechanical performances, stripping performance, extrusion coking resistance, flame retardation performance, conductivity and temperature stability is obtained through reasonably designing the formula of the semi-conductive shielding material, adopting the coordination resistance and the most appropriate content ratio of all components and using a reasonable preparation technology.

Description

A kind of high pressure level power cable semiconductive shieldin material
Technical field
The invention belongs to a kind of semiconductive shieldin material, specifically, more particularly to a kind of high pressure level power cable semiconductive screen Cover material.
Background technology
The high pressure or ultra-high voltage cross-linking polyethylene-insulated power cable semiconductive shieldin material of 110kv and above, due to Its working environment is in high voltage, in high current, it is desirable to which it can balance high electric field, voltage is kept stabilization, and this requires shielding The particulate that the smoothness that material and insulating surface form surface is reached in ultra-smooth effect, i.e. per unit cm2 more than 25nm can not be more than 2.And due to shielding material contact copper core, it is under high currents, easily aging by metal catalytic, cause its service life short, this is just It is required that shielding material has the ageing properties of resistance to metal catalytic higher, so as to extend its service life.Existing 35KV and following crosslinking It is primary raw material that polyethylene-insulated power cable all uses ethylene vinyl acetate, adds general conductive black and paraffin to be produced Processing, the need for properties of product far can not meet high pressure or ultra-high voltage cross-linking polyethylene-insulated power cable semiconductive shieldin material.
The content of the invention
It is an object of the present invention to provide a kind of high pressure level power cable semiconductive shieldin material, to overcome factice for filling in the prior art Defect.
The present invention is realized using following technical scheme:A kind of high pressure level power cable semiconductive shieldin material, by comprising with The raw material composition of lower weight part ratio:100 parts of base-material, conductive black 45-48 parts, remover 3-5 parts, antioxygen/matal deactivator 5-8 Part, crosslinking agent 4-6 parts, reinforcing agent 3-5 parts, age resistor 0.5-1 parts, plasticizer 10-12 parts.
Described base-material is mixed by ethylene propylene diene rubber and vinyl-vinyl acetate copolymer, and the ratio of the two is Ethylene propylene diene rubber:Vinyl-vinyl acetate copolymer=1:5-7.
The reinforcing agent is four acicular type zinc oxide crystal whisker;
The crosslinking agent is cumyl peroxide;
The age resistor is N- (1,3- dimethyl) butyl-N'- diphenyl-para-phenylene diamines;
The plasticizer is zinc stearate.
Compared with prior art, the beneficial effects of the invention are as follows:
The reasonable design of the present invention formula of semiconductive inner shield material, by the coordinative role of each component and the most suitable Content proportioning, be aided with rational preparation technology, obtain with excellent mechanical performance, stripping performance, extrude anti-incipient scorch The semi-conductive shielding material of energy, fire resistance, electric conductivity and temperature stabilization performance.
Specific embodiment
