Description
Technical field
The present invention relates to a kind of double spraying methods of outdoor vacuum circuit breaker substrate, outdoor vacuum circuit breaker substrate and outdoor reals
Empty breaker, belongs to electrical equipment technical field.
Background technology
In electric system, outdoor high-voltage vacuum breaker (such as ZW7-40.5 types vacuum circuit breaker) is a kind of is suitable for respectively
The breaker in kind of frequent operation place, is usually implemented as the breaker that industrial and mining enterprises, power plant and substation use, can be used into
Row circuit protection and control etc..
The overall structure of outdoor vacuum circuit breaker of the prior art is porcelain knob, is made of upper and lower insulator, vacuum extinction
Room is mounted in upper insulator, and lower insulator is pillar, and lower insulator seat is on substrate, and the surface treatment of vacuum circuit breaker substrate is to open circuit
The stability of device seems particularly significant.At present, substrate is generally using electrophoresis+plastic-spraying or the surface treatment mode of galvanizing.Its
In, the use of the defects of mode that plastic-blasting surface is handled is the easy peeling in surface, chip off-falling.And hot dip galvanizing process is used to produce then not ring
It protects, severe operational environment.In addition, galvanizing metacoxal plate is susceptible to surface irregularity phenomenon, mounting surface out of plumb can be caused, is held
Easily cause that switching manipulation is dumb to result even in accident.
The content of the invention
It is an object of the invention to provide a kind of double sprays of the outdoor vacuum circuit breaker substrate that can improve substrate surface quality
Coating method.
The present invention also aims to provide the outdoor vacuum circuit breaker substrate and use the base that the above method handles
The outdoor vacuum circuit breaker of plate.
To achieve the above object, the technical solution of the double spraying methods of outdoor vacuum circuit breaker substrate of the invention is：
A kind of double spraying methods of outdoor vacuum circuit breaker substrate, include the following steps：
1) vacuum circuit breaker substrate is subjected to blasting treatment, then 30-40min is toasted at 245-255 DEG C, in vacuum circuit breaker
Device substrate surface spraying weight zinc epoxy anticorrosion bottom powder forms priming coat, then keeps the temperature 5-8min at 245-255 DEG C, obtains precoating base
Plate；
2) top coat is formed in precoating substrate surface spray epoxy powder, then keeps the temperature 30- at 210-230 DEG C
40min to get.
The double spraying methods of outdoor vacuum circuit breaker substrate of the present invention are using first spraying weight zinc epoxy anticorrosion bottom powder and then again
The mode of spray epoxy powder forms priming coat and top coat duplex coating in substrate surface.Heavy zinc ring as priming coat
Oxygen anti-corrosion bottom powder can play the role of forming a connecting link between substrate matrix and the epoxy resin layer of top coat, make therebetween
With power is firmly combined, the problem of peeling or even chip off-falling occur for the coating on substrate is avoided.
Substrate is first carried out blasting treatment by the present invention before spraying bottom coating, can form one in the matrix surface of substrate
The scraggly surface texture of layer improves the adhesive force on surface, is conducive to weight zinc epoxy anticorrosion bottom powder and is closely tied with matrix surface
It closes, even if when substrate is in the more violent temperature change of environment, will not cause because of expansion or the contraction of substrate
Face coat peeling comes off.Meanwhile blasting treatment can also eliminate the microcosmic wedge angle burr of substrate surface, further improve base
The surface quality of plate coating.
The substrate of the present invention toasts 30-40min after blasting treatment, at 245-255 DEG C, enables to substrate inner homogeneous
Ground is in the state of expanded by heating, then in this state to its surface spraying weight zinc epoxy anticorrosion bottom powder, anti-corrosion bottom powder energy
It is enough to be closely incorporated in the scraggly structure of substrate surface, and after being cooled down in the later stage, be conducive to obtain fine and close coating knot
Structure.
It is kept the temperature after the powder of spraying weight zinc epoxy anticorrosion bottom at 245-255 DEG C, the curing temperature of the temperature than in the prior art
It spends much higher, is on the one hand conducive to the state that substrate keeps the expanded by heating of preceding processes, on the other hand can also make weight zinc ring
Oxygen anti-corrosion bottom powder is as early as possible into the cured state of beginning.On this basis, the present invention controls the time of heat preservation to make weight for 5-8min
Zinc epoxy anticorrosion bottom powder can be only in the state of semi-solid preparation, it is impossible to thoroughly cure.And after spray epoxy powder, in 210-
30-40min is kept the temperature at 230 DEG C so that the epoxy resin powder on surface layer and the heavy zinc epoxy anticorrosion bottom powder of priming coat are carried out at the same time admittedly
Change, be conducive to the synchronous between two layers of coatings, when environment temperature acute variation is run into the later stage, avoid between two layers of coatings
There is the asynchronous caused coating peeling of expansion or shrinkage.
In order to further improve the surface quality of substrates coatings, it is preferred that the double sprayings of above-mentioned outdoor vacuum circuit breaker substrate
Method includes the following steps：
1) vacuum circuit breaker substrate is subjected to blasting treatment, then 35min is toasted at 245 DEG C, in vacuum circuit breaker substrate
Surface spraying weight zinc epoxy anticorrosion bottom powder, then keeps the temperature 5min at 245 DEG C, obtains precoating substrate；
2) precoating substrate surface spray epoxy powder, then at 210 DEG C keep the temperature 35min to get.
The double spraying methods of outdoor vacuum circuit breaker substrate of the present invention have more obvious for the larger substrate of thickness
Effect, generally, the thickness of the outdoor vacuum circuit breaker substrate is not less than 20mm.Further, which is preferably 20-
25mm。
The material of substrate is generally using Q235 steel, i.e. 10# steel.
In order to which substrate is in relatively stable state when ensureing to spray weight zinc epoxy anticorrosion bottom powder, after 245-255 DEG C of baking
The spray treatment for carrying out weight zinc epoxy anticorrosion bottom powder is taken out immediately, generally, substrate is fetched into out from 245-255 DEG C of baking oven
Begin to carry out the time interval between the spraying of weight zinc epoxy anticorrosion bottom powder and be no more than 10s.Correspondingly, spraying weight zinc epoxy anticorrosion bottom
After powder, after 245-255 DEG C of semi-solid preparation, the time interval being fetched into since baking oven between spray epoxy powder is not yet
More than 10s.
Product of the prior art may be employed in weight zinc epoxy anticorrosion bottom powder, in order to improve between priming coat and substrate surface
Combination power, it is preferred that in the heavy zinc epoxy anticorrosion bottom powder mass content of zinc be 80%-85%.
During blasting treatment, for the scraggly configuration state that substrate surface structures is made to reach required, generally, described
Blasting treatment uses solid sandblasting, and the air consumption of single rifle is 1M3/min.The pressure of spray gun is not easy too small during sandblasting, generally, institute
The pressure for stating blasting treatment is 0.5-0.6MPa.
The thickness of priming coat can neither too greatly can not be too small, thickness too it is small be easy to cause substrate surface formation one layer
Scraggly surface texture cannot be completely covered by priming coat, some wedge angle protrusions is made to extend into top coat, influence table painting
The surface quality of layer, generally, the thickness of the priming coat is 0.4-0.5mm.The thickness of the top coat is 0.5-0.6mm.
