Abstract
Provided is an adhesive for a direct-current supporting column insulator. The adhesive is prepared from, by mass, 60-90 parts of solvent dimethyl carbonate, 15-30 parts of cosolvent glycol derivatives, 5-10 parts of nonionic surfactants, 2-5 parts of abrasive nanometal oxide, 1-5 parts of diffusant dichloromethane, 0.5-2 parts of detergent assistant N-alkyl pyrrolidone, 0.2-1 part of stabilizer coconut oil diethanolamide, and 1-3 parts of polymethylsiloxane. Detergent can effectively clear away stains on the surface of an insulator antifouling flashover coating under the environment of high saline-alkali and high industrial pollution, excellent hydrophobicity and migration of the hydrophobicity of the surface of an insulator are recovered, and therefore the capacity of effectively ensuring power equipment to operate safely is achieved.
Description
Technical field
The present invention relates to adhesive field, the stickup tackiness agent of ceramic core rod and rubber skirt on especially a kind of insulator.
Background technology
Existing high-tension apparatus insulator is mainly divided into two large classes: the insulator of ceramic material and silicon rubber hollow composite insulator.The structure formation of insulator is a lot, has straight shape, taper and waist drum etc., but the weight of insulator is large, and easily injure miscellaneous equipment after blast, anti-pollution characteristic is low, and sintering technology is complicated; Hollow combined insulator own wt is light, and be 1/4 ~ 1/10 of insulator, without hidden peril of explosion, have good hydrophobic nature, anti-pollution characteristic significantly improves compared with insulator, and the energy consumption of moulding process is well below insulator.Existing hollow combined insulator, it is that bulk material adopts room temperature vulcanized silicone rubber (RTV) that manufacture method mainly contains two kinds: one, makes single umbrella body, then adopts silicon rubber cementation integrally; Two is that umbrella body material adopts fluid silicone rubber through injection molding.These method shortcomings be single umbrella body through cementation integrally, easily there is the phenomenons such as cracking in abutting edge, secondly the insulation galvanic corrosion of fluid silicone rubber and ageing resistance poor.
Adhesive specially research for insulator porcelain post core and rubber in prior art is less, is necessary to be improved it.
CN101430954A discloses a kind of preparation method of composite insulator silicon rubber jacket, first take respectively by weight percentage the silicon rubber of 35% ~ 46%, 12% ~ 18% white carbon black, the control agent of 0.2% ~ 0.4%, the coupling agent of 0.08% ~ 0.1% and 40% ~ 48% fire retardant, then through mixing, vacuumize and make rubber master batch; Then take rubber master batch, add tinting material and vulcanizing agent, park more than 24 hours after mixing, namely make silicon rubber gross rubber; Then namely injection molding make composite insulator silicon rubber jacket.Compared with traditional method, the cohesive strength of silicone rubber jacket and porcelain core rod is greatly improved.
CN101877258A discloses the formula of a kind of disc-type suspension type double insulation composite insulator and dielectric tackiness agent, wherein disc-type suspension type double insulation composite insulator comprises web member under metal upper connector, isolator, metal, metal upper connector and isolator are provided with tackiness agent, are provided with insulation rod under metal between web member and isolator.Dielectric tackiness agent comprises the composition of following weight part: the epoxy resin of 20-50, the cement of 20-40, the conduction powder of 5-20, the organic solvent of 10-20.
Summary of the invention
The invention provides a kind of insulator porcelain plug and rubber skirt tackiness agent and using method thereof, this tackiness agent improves the bonding strength of porcelain core rod and hot-vulcanized silicone rubber skirt, and there is the electrical insulation capability of superelevation, effectively can strengthen the serviceability of composite post insulator.
The object of the invention is to solve by the following technical programs:
A kind of direct current support insulator tackiness agent, be made up of the component of following massfraction, uncle amino polysilane 35-50 part, linear phenolic resin 10-20 part, epoxy resin 15-30 part, boric acid 2 ~ 20 parts, methylcarbonate 40-80 part, organic titanium adhesion promotor, the mass percent concentration of described boric acid is greater than 50%.
The general structure of the amino polysilane of described uncle is R
1-(Si (OR
2)
(3-a)r
3 a)
n, wherein R
1the n valency organic group at least with a tertiary amino, R
2be alkyl or the acyl group with 5-8 carbon atom, a selects the numerical value of 1 or 2; R
3be selected from the alkyl of H or C1-C4.
Described epoxy resin is preferably bisphenol A diglycidyl ether.
Described organic titanium adhesion promotor is titanic acid ester or titanium chelate, titanate ester as four (n-butoxy) titanium, four (isopropoxy) titanium, titanium chelate as two in two (isopropoxies) (Acetyl Acetone) titanium.
Tackiness agent of the present invention adopts the amino polysilane of uncle, linear phenolic resin, epoxy resin cooperatively interacts preparation, effectively can put forward the porcelain core rod of support insulator and the bonding strength of hot-vulcanized silicone rubber, cohesive strength is made to improve more than 50% than conventional adhesive, and the using method adopting this tackiness agent corresponding, in use boric acid thus improve the activity energy of binder molecule, effectively enhance the serviceability of composite post insulator, improve conforming product rate more than 50%.
