Description
Technical field
The present invention relates to special silastic material technical field, be specifically related to conductive silicon rubber combination in cold shrinking power cable adjunct
Thing and manufacture method thereof.
Background technology
Conductive silicon rubber has production the most very early, is mainly used in conduction button, conduction zebra bar, medical treatment conductive sheet
And the field such as antistatic material.Common production method is, uses methyl vinyl silicone rubber or methyl ethylene to mix
Raw material based on material glue, directly the conductive filler (conductive carbon black or metallic conductive fillers) of outsourcing on a mill until or banburying
Being simply mixed in machine, reach required resistance requirement, technical requirement is not the highest.
The conductive silicon rubber generally produced, because of physical property deviation, is not suitable in cold shrinking power cable adjunct.Conductive silicon rubber
It is applied in cable accessory play electric field stress peptizaiton, is the core of silicone rubber cable accessories connecting material, by product
Molding occupation mode can be divided into Conductive silicon rubber material and the conductive silicon rubber of on-expansible prefabrication type of expansion cold-shrink type
Material.Need before material (the middle typically all circle hollow) use of so-called expansion cold-shrink type conductive silicon rubber, i.e. forming
Supporting its aperture PVC material in advance and be extended to about 300%, the cable connector metalwork connected puts into the silicon expanded
In rubber-moulding body, by taking plastic support bar away, cylindrical shape silicone rubber can quickly retract to close to original size, thus electricity
Cable connection core is tightly embraced and is integrally forming, and plays sealing waterproof action simultaneously.The silicone rubber cable accessories molding of on-expansible prefabrication type
After, it is not necessary to expansion is mounted directly use, and it is the highest to the physical property requirements of silastic material, and common conductive silicone rubber can
To meet requirement.If producing cold-shrink type silicone rubber products by the Conductive silicon rubber material of common non-cold-shrink type, take out after expansion
It is to contract not to be back to required size to walk support bar, say, that it can not hold cable core tightly, centre have air and
Gap, if cable occurs that during operation power this phenomenon can cause electric power accident to occur.
Summary of the invention
The purpose of the present invention is contemplated to solve above-mentioned technical problem, and provides conductive silicon rubber group in cold shrinking power cable adjunct
Compound and manufacture method thereof.
In cold shrinking power cable adjunct of the present invention, conductive silicon rubber composition includes following components in parts by weight:

Silicone oil 0-20 zinc stearate 0.05-1 peroxide vulcanizing agent 0.5-3 coupling agent 0-0.8.
The consumption of described coupling agent is the 0-2% of conductive black consumption.
In cold shrinking power cable adjunct, the manufacture method of conductive silicon rubber composition comprises the following steps:
One: pretreatment of raw material
First conductive carbon black being put in mixing plant, adding coupling agent, to carry out stirring pretreatment in 0-5 hour under room temperature stand-by；
Two: banburying
A. first methyl vinyl silicone rubber is pressed formula consumption to put in banbury, and put into zinc stearate simultaneously；
Divide 1-2 input white carbon the most again, put into silicone oil simultaneously, dosing operation next time after being mixed into bulk, can be carried out；
The most then divide 2-3 time and put into conductive carbon black (surface is handled well in advance), treat methyl vinyl silicone rubber and carbon black
Conductive carbon black operation can be thrown after being sufficiently mixed into bulk next time；
D. mixture temperature controls, at 30 DEG C-120 DEG C, to be cooled to room temperature, jelly expect after discharging；
Three: mill
The glue that banburying is good expects, after room temperature cooling in 2-3 hour, to place into the enterprising one-step melting of mill uniform, Bao Tongyi time
Blanking；
Three: filter
The Conductive silicon rubber material that mill is mixed, is filtered by filter, and filter temperature controls at 30 DEG C-120 DEG C.
Four: add sulfur
The conductive silicon rubber filtered adds vulcanizing agent on a mill until.
The invention have the advantages that the present invention, by raw material is modified process in advance, selects and Reasonable meticulously
The various materials of ratio, formulated through the multiple working procedure such as banburying, mill；Overcome the cold-shrink type of other manufacturer production the most domestic
Conductive silicon rubber generally deposits the situation that before using after expansion, nerve is bad.Considering of cold shrinking power cable adjunct product nerve is logical
Often determining with the index of mensuration " surely stretching permanent deformation ", the cold shrinking power cable adjunct Conductive silicon rubber material of the present invention meets country
Standard " JB/T10740.1-2007 ".
