Step 4, it is cooled and shaped,
Step 5, applying coating.
The features of the present invention also resides in,
The specific formula that raw material is weighed in described step 1 is：Odium stearate：0.3% -1%, antioxidant：2%- 5%, titanium dioxide：1.5% -3%, zinc oxide：3% -4.5%, accelerator：5%, antistatic additive：0.5% -1.8%, Calcium carbonate powder：5%-11%, asbestos fibre：8%-17%, graphite fibre：4%-18%, surplus are neoprene；
Described neoprene is prepared in accordance with the following methods：100 parts of chlorobutadiene is sent into oil phase and prepares kettle, by 0.9 Part tert-dodecyl mercaptan add, turn on agitator stirs and to being completely dissolved, adds 5 parts of mersolates, with being made To oil phase；150 parts of softened waters, 0.95 part of sodium hydroxide and 0.6 part of dispersant are stirred and are configured to aqueous phase；Preparation is drawn Agent solution is sent out, the anthraquinone-2-sulfonic acid sodium solution that the potassium persulfate solution and weight fraction for being 85% by weight fraction are 15% is matched somebody with somebody Into initiator and terminate agent solution；Then initiator solution is added in above-mentioned oil-phase solution, is polymerize；Reaction 3 hours Wait to add and terminate agent solution terminating reaction, be then condensed and be drying to obtain.
Described step 2 is sufficiently well mixed specifically, the raw material weighed in step 1 is crushed.
Described step 3 specifically, mixed raw material is heated into molten condition and is incubated 10 minutes, heating it is same When be stirred, and add accelerator；
Described step 4 obtains rubber of insulating accordingly specifically, be put into after the completion of reaction in mould after cooling Glue part.
Described step 5 is specifically, rubber is fitted into roller, and mesh is less than rubber external diameter, to ensure rubber Glue product does not drop from roller, will install the roller of rubber, is put into the casing of closing；Used in the casing of closing Fan blows molybdenum disulphide powder, molybdenum disulfide particles is suspended in atmosphere, now rotating cylinder, makes molybdenum disulphide powder uniform The surface for being attached to rubber parts；Take out the rubber after coating to be put into dry roller, rotating cylinder, make addition Bullet particle produces frictional impact with rubber article, and the coating of molybdenum disulfide will uniformly be attached to the surface of rubber parts.
The invention has the advantages that the power equipment electro-insulating rubber prepared using the method for the present invention, is ensured fabulous Insulating properties, resistance to elevated temperatures and ageing resistace, increase the service life of product, strengthen using effect.
