Description
Technical field
The invention belongs to power system power transmission and transforming equipment technical field of coatings, be specifically related to a kind of special RTV antifouling flush paint of electrification in high voltage.
Background technology
Under adverse weather condition (like rain, mist, dew etc.), flashover can be there is along moist insulator surface, cause power system pollution flashover accident. in power system, the scope involved by grid pollution flashover accident is wide, power off time is long, the serious safe operation threatening power transmission and transforming equipment, huge economic loss is caused to national economy, therefore the pollution flashover problem of electrical network is always up the important topic of puzzlement electric utility development, how effectively to solve electrical network pollution flashover problem and have become as the important process ensureing that power system security produces, at present, the measure of antifouling work is nothing more than 4 kinds, the first is to adopt to adjust the measure climbed, i.e. increase insulator quantity climbed in tune, increase insulator quantity and can bring a series of problem, as increased the burden of shaft tower, the means of the second antifouling work are insulator cleanings, although play a role, but the workload cleaned is very big, and the cleaning that generally can only have a power failure, the method of the third antifouling work adopts composite insulator exactly, and composite insulator can play good antifouling work effect, but it is costly, and quantities is big, the means of the 4th kind of antifouling work are coated with RTV coating exactly, and this is also present stage most widely used method.
The eighties in 20th century, China introduced a kind of room temperature vulcanized silicone rubber coating for electric power Bears external insulation equipment (RTV coating) from successful foreign, obtain at home promoting widely and application, substantial amounts of facts have proved, it is a kind of most economical for being coated with RTV coating at power equipment external insulation, the measure of maximally effective antifouling work accident, but the coating operation of our domestic RTV coating is all have a power failure at the construction field (site) at present, it is applied in electrical equipment no-voltage situation and is coated operation, and weather is fine when requiring to construct, without dust storm, without airborne dust, air drying, proper temperature, frostless, without snow, construct when without rain and dew, coating effect can be ensured.
If can develop a kind of can when electrical equipment is charged the on-the-spot Novel safe antifouling flush paint being coated operation when need not have a power failure, and research and develop a set of safety work instrument supporting with it and can implement the charged spraying operation of antifouling flush paint. Out tape electrospray operation can make way for other must the job of power failure operation, unvaluable with the contention of other work posts power off time and limited working space, it is ensured that its task performance give full play to the lifting with quality. Good weather conditions can be substantially effectively selected to be coated operation, it is ensured that the coating quality of coating, because the time of power failure operation not necessarily catches up with the ideal climate condition being suitable for coating operation. The most important thing is to reduce the great economic loss caused because of power failure. Popularization with electrospray antifouling flush paint technology and application have social benefit and huge economic worth widely.
Up to highland, Chongqing electric power science and technology limited Company protects safety work instrument by patent application, respectively application number to be " 360 ° of rotary apparatuss of electrification in high voltage " of " 2016200497080 ", application number be " electrification in high voltage 110kV, 220kV, 500kV antifouling work special purpose device " of " 2016200496020 ", application number is " 2016200495117 " " electrification in high voltage spraying intelligence flush coater ". Those skilled in the art need badly and develop the matching used on-the-spot Novel safe antifouling flush paint being coated operation when need not have a power failure when electrical equipment is charged of a kind of and above-mentioned spray equipment.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of special RTV antifouling flush paint of electrification in high voltage, RTV antifouling flush paint disclosed by the invention has improved performance, to realize coating in spraying process, does not burn under atomization condition, inexplosive requirement.

1, the present invention adopt aluminium hydroxide it be used for improving arc resistance and anti creepage trace in RTV coating. Because when electric arc ablator surface, the temperature on local material surface can significantly improve, aluminium hydroxide can decomposite rapidly water of crystallization and absorb amount of heat, thus reducing the temperature of material surface. The water of crystallization that aluminium hydroxide decomposites is at Al2O3Catalytic action under, when can decompose with organic material produce free carbon react, generate volatile CO and CO2, terminate the formation of the carbonization passage of conduction. Compared with aluminium hydroxide, polysiloxanes is apolar substance, and the surface property differences of the two is very big, it is easy to cause the two-phase laminated flow of polysiloxanes and filler, thus affecting the various aspects of performance of coating. So the surface of aluminum hydroxide that the present invention adds have employed silane coupler and its surface carried out modification, because at high temperature, the moisture of surface of aluminum hydroxide is removed, the aluminium hydroxide reunited obtains depolymerization, the polar group of surface of aluminum hydroxide is replaced by the organic group of silane coupler simultaneously, so substantially increase the compatibility of aluminium hydroxide and polysiloxanes, also improve the arc resistance of RTV coating.
2, the present invention adds nano material to combine with the polydimethylsiloxane in formula, nano material organically combines with RTV molecule, the special natures such as the physical dimension effect of nano material microcosmic, skin effect, quantum size effect and macro quanta tunnel effect are given full play to, make the intermolecular cohesiveness of coating increase substantially, improve the physicochemical property of coating in all directions; Can activate further little molecule hydrophobic group balancedly, in an orderly manner, enduringly to pollution layer migrate; Nano material closely surrounds RTV, utilizes the anti-uv-ray that nano material is remarkable, RTV plays strong shielding protection effect, thus RTV molecule is played a very good protection, drastically increases the weather-proof domestic animal of coating.
3, the present invention limits methyl triacetoxysilane and first mixes with dibutyl tin dilaurate, is first mixed with dibutyl tin dilaurate by methyl triacetoxysilane, can remarkably promote the curing reaction of coating.
4, solvent for use of the present invention is MC-318 double solvents, and it can ensure that coating does not burn under atomization condition in charged spraying process, do not explode, without flashover in charged situation, and environment friendly and pollution-free.
