Description
Technical field
The present invention relates to the manufacture method of CABLE MATERIALS, be specifically related to a kind of manufacture method of ageing-resistant electro-insulating rubber CABLE MATERIALS.
Background technology
Cable sheath is the outermost layer of cable, and cable sheath material not only needs excellent physicals, as tensile strength, elongation at break etc., also needs to have good flame retardant properties simultaneously.In rubber insulation conventional be Ethylene Propylene Terpolymer as base-material, with vulcanizing agent DCP and vulcanization accelerator TAC, the shortcoming of rubber unvulcanizate is: elongation at break is lower, and in sulfidation, processing range is narrower, if when extruding temperature too high to be easy to elongation at break defective.
Summary of the invention
The object of this invention is to provide a kind of manufacture method of ageing-resistant electro-insulating rubber CABLE MATERIALS, the ageing-resistant electro-insulating rubber CABLE MATERIALS that this manufacture method obtains is conducive to inorganic powder and adds evenly, processing range is extensive, endless vulcanization temperature still keeps higher elongation at break between 190 DEG C ~ 210 DEG C, also greatly reduces costs.
For achieving the above object, the technical solution used in the present invention is: a kind of manufacture method of ageing-resistant electro-insulating rubber CABLE MATERIALS, comprises the following steps:
Step one. first by chlorinatedpolyethylene 8 ~ 14 parts, 19 ~ 21 parts, ethylene-octene copolymer elastomerics, percentage ratio is mixing in Banbury mixer by weight;
Step 2. in described Banbury mixer, add 800# paraffinic base rubber oil 5 ~ 8 parts, activated magnesia 0.8 ~ 1 part, active zinc flower 1 ~ 2 part, stabilizer 0.3 ~ 0.6 part, Microcrystalline Wax 1 ~ 2 part, titanium dioxide 0.7 ~ 0.9 part, 4 again, 4 ' two (α, α dimethyl benzyl) pentanoic 0.5 ~ 0.6 part, mixing 2 ~ 3min;
Step 3. then, modification calcinated argil 25 ~ 31 parts, superfine talcum powder 5 ~ 7 parts are added mixing 3 ~ 5min in described Banbury mixer, glue stuff compounding discharged by Banbury mixer;
Step 4. by described glue stuff compounding thin-pass 1 ~ 2 time on a mill until, put glue 2 ~ 3 times, then through a strainer filtering rubber, filter screen is three metafiltration nets, is respectively 40 orders, 80 orders and 40 orders simultaneously;
Step 5. after the rubber filtered is deposited 24 hours, sizing material is reentered into mixer mixing, adds vulcanizing agent dicumyl peroxide 1 ~ 2 part, the mixing rear discharge of triallyl cyanurate 1.2 ~ 1.3 parts simultaneously.
In such scheme, the further improvement project in technical scheme is as follows:
