Description
Electrically insulated sealing rubber washer of the present invention belongs to rubber-type electric insulation sealing material.
For a long time, China's high voltage supply system is to adopt the nuditing wire power supply, is main insulation with the porcelain vase, is air isolation between phase and phase, therefore, various security incidents often takes place, even human casualty accident.Especially in recent years, take place repeatedly especially, cause the financial loss that to estimate by the electric serious accident that causes.For this reason, it is the construction and the transformation of the totally-enclosed high voltage supply system of supplementary insulation with the insulated conductor that the several metropolitan power supply departments of China are being carried out a cover, to reverse the power supply situation that present accident is sent out repeatly, the insulated enclosure problem of insulated conductor joint has been proposed thereupon, existing splicing tape, PVC plastic tape, materials such as various insulating plastics heat-shrink tubes all can not reach high pressure resistant, ageing-resistant, easy to operate, cheap etc. composite request.It is a kind of novel to press for development, and particularly ageing-resistant insulated enclosure material is with the construction of satisfying ultra-high-tension power transmission line and electrical installation project and the needs of transformation.As far back as the sixties, U.S. kearney company just develops a kind of new electrically insulated sealing rubber washer, and Airseal by name and Aquaseal obtained effect preferably in the joint of electrical installation project connects, but price are more expensive, reaches 10,000 dollars/ton.
Task of the present invention is to develop a kind of insulation strength height, resistance to air loss is good, unreactiveness is strong, the non-volatility solvent, heat-resisting, cold-resistant, ageing-resistant, have enough viscosity and forever plastic, and low-cost electrically insulated sealing rubber washer, to satisfy the needs of modern high-voltage electrical apparatus installation work technological improvement.
The technical scheme of electrically insulated sealing rubber washer of the present invention has two: one, with isoprene-isobutylene rubber 268 or isoprene-isobutylene rubber 301 is basic raw material, allocates mixed inert weighting agent and carbon black into, tenderizer, zinc oxide, raw materials such as white carbon black are made coventional type electrically insulated sealing rubber washer or film; Its two, be basic raw material with isoprene-isobutylene rubber 268 or isoprene-isobutylene rubber 301 and chlorosulfonated polyethylene, allocate the mixed inert weighting agent into, carbon black, tenderizer, zinc oxide and mix fire retardant and white carbon black is made flame retardant type electrically insulated sealing rubber washer or film.
Specific embodiments of the present invention is:
1. the technical formula of coventional type electrically insulated sealing rubber washer is, with isoprene-isobutylene rubber 268 or isoprene-isobutylene rubber 301 is 100 parts, allocate into 250～350 parts by silicon powder and talcum powder (also potter's clay, mica powders etc. are acidproof, alkaline-resisting, water-absorbent is low, the raw material of good insulation preformance) (wherein silicon powder is no less than 150 parts to the mixed inert weighting agent of Zu Chenging, talcum powder is no less than 100 parts) and 5～12 parts carbon black, 56～76 parts by transformer oil, paraffin, (wherein transformer oil is no less than 50 parts to the tenderizer that stearic acid is formed, paraffin is no less than 5 parts, stearic acid is no less than 1 part), the white carbon black of 3～5 parts zinc oxide and 10～20 parts.
2. the technical formula of flame retardant type electrically insulated sealing rubber washer is, chlorosulfonated polyethylene with 85～95 parts isoprene-isobutylene rubbers 268 or isoprene-isobutylene rubber 301 and 5～15 parts is a basic raw material, allocate into 250～350 parts by silicon powder and talcum powder (also potter's clay, mica powders etc. are acidproof, alkaline-resisting, water-absorbent is low, the raw material of good insulation preformance) (wherein silicon powder is no less than 150 parts to the mixed inert weighting agent of Zu Chenging, talcum powder is no less than 100 parts) and 5～12 parts carbon black, 56～76 parts by transformer oil, clorafin, paraffin, (wherein transformer oil is no less than 10 parts to the tenderizer that stearic acid is formed, clorafin is no less than 40 parts, paraffin is no less than 5 parts, stearic acid is no less than 1 part), 3～5 zinc oxide, 33～50 parts by Sb
2O
3, decabromodiphynly oxide or chlorocarbon 70, Al(OH)
3The mixing fire retardant of being formed (Sb wherein
2O
3Be no less than 15 parts, decabromodiphynly oxide or chlorocarbon 70 are no less than 15 parts, Al(OH)
3Be no less than 3 parts) and 15～25 parts white carbon black.
Its process for making is, earlier with the mixed inert weighting agent, carbon black, zinc oxide etc. allocate that raw material sieves respectively into, selected back with plasticate after isoprene-isobutylene rubber 268 or 301 basic raw material carry out mixing, again through extruding filtration, being rolled into film, stick lining paper after the cooling, section has just become spendable insulated enclosure film.
The present invention has following performance and advantage:
