Technical field
The utility model relates to a kind of compound protective coating of motor insulation structure, the motor insulation structure that mainly be applicable to have salt spray resistance, the Almightiness type weatherabilities such as humidity, anti-solvent, radiation hardness, low temperature resistant, cold-hot impact, wearability requires.
Background technology
Along with the fast development of national economy, it is more and more harsher that the environment for use of motor becomes, and the protection of insulation system is seemed to more and more important.While as motor, moving under the particular surroundings such as coastal or altitude environment; insulation system usually needs to have simultaneously salt spray resistance, humidity, radiation hardness, low temperature resistant, cold-hot impact, anti-solvent, the multinomial performance such as wear-resisting, and it is excellent many that three more traditional anti-paint performances are wanted.If not for the protection of these erosions or protect improperly, after long-term the erosion, insulation system is deteriorated, can reduce significantly the service life of motor.
In prior art, the patent No. is that the Chinese invention patent of ZL 200410067980.3 discloses a kind of " composite anticorrosive heat insulating coating ", and it comprises: the epoxy resin of take is got the topcoat of ethene as base-material as the inter coat of base-material and the high chlorination of take as the primer coating of base-material, the Hydroxylated acrylic resin of take.Application number is 201110086584.5 Chinese invention patent " a kind of composite coating and spraying method thereof that prevents marine biofouling " employing HVAF and cold spray technique; on metallic matrix, prepare transition zone, insulating coating and nonpolluting coating, reach the purpose of anticorrosion and antifouling; This spraying method mainly comprises the following steps: (1) metal base surface pretreatment; (2) HVAF; (3) cold spraying.Is this composite coating by the nickel of 80～100 μ m-chromium Ni? the red copper nonpolluting coating of the aluminium oxide of Cr transition zone, 180～250 μ m and titanium oxide compound inslation coating and 800～1000 μ m forms, and total coating thickness is 1000～1500 μ m.Application number is 201220156604.1 Chinese utility model patent " corrosion resistant steel pipe with composite coated layers ", discloses at described outer surface of steel tube and has been coated with successively epoxide powder coating layer, polyolefin adhesive coating and polyethylene coating.How above-mentioned prior art, carry out the effectively problem of protection to insulation system when all failing to solve motor and moving under the particular surroundings such as coastal or altitude environment.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of electrical machine insulation anticorrosive composite coating that can effectively protect the anti-multiple environment such as salt fog, humidity, solvent, radiation, low temperature, thermal shock, wearability.
The technical scheme addressed the above problem that the utility model adopts is: described electrical machine insulation anticorrosive composite coating is positioned at the surface of motor insulation structure, by the first coating and the second coating, be composited, described the first coating is epoxy resin enamel, be painted on the motor insulation structure surface, the second coating is fluorocarbon enamelled paint, is sprayed on the first coating.
Described the second coating is thicker than the first coating.It is base-material that described the first coating adopts heat resistance, the good macromolecule epoxy resin of insulating properties, and high weather-proof macromolecular material is curing agent.Described the first coating temperature classification is more than 180 ℃.It is base-material that described the second coating adopts 4F type fluorocarbon resin, and the macromolecular material of anti-the xanthochromia is curing agent.Described electrical machine insulation anticorrosive composite coating can be used for the protection of motor insulation structure.
Adopt above-mentioned electrical machine insulation anticorrosive composite coating; can make motor insulation structure have the Almightiness type weatherabilities such as anti-ultraviolet, salt spray resistance, humidity, anti-solvent, radiation hardness, low temperature resistant, cold-hot impact, wearability, adapt to the demand of the multiple particular surroundings such as coastal or altitude environment.What is particularly worth mentioning is that, the ultra-violet resistance of independent the first coating epoxy resin enamel can be poor, the adhesion property of independent the second coating fluorocarbon enamelled paint is general, but, after both form composite coating, not only still have original various performance separately, and due to complex effect, also make the performance of its anti-ultraviolet, salt spray resistance, humidity significantly promote, had new performance, the protection effect of internal layer insulation system has significantly been strengthened, obtained unforeseeable technique effect.
The accompanying drawing explanation
Fig. 1 is the structure chart of the utility model electrical machine insulation anticorrosive composite coating.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, described electrical machine insulation anticorrosive composite coating is positioned at the surface of motor insulation structure 3, by the first coating 1 and the second coating 2, be composited, described the first coating 1 is epoxy resin enamel, be painted on motor insulation structure 3 surfaces, the second coating 2 is fluorocarbon enamelled paint, is sprayed on the first coating 1.
This electrical machine insulation anticorrosive composite coating is first in the first thinner coating 1 of insulation system 3 surface sprayings, after the first coating 1 is fully solidified, then the second slightly thick coating 2 of spraying.The first coating 1 and insulation system strong adhesion, and adhering to of the second coating 2 and the first coating 1 is firm, thereby the anti-various environmental performances such as the salt spray resistance, humidity, anti-solvent of nexine insulation, low temperature resistant, cold-hot impact, wearability, radiation hardness have fully been guaranteed.
It is base-material that the first coating 1 adopts heat resistance, the good macromolecule epoxy resin of insulating properties, and high weather-proof macromolecular material is curing agent.After solidifying, product has good adhesive force, weatherability, chemicals-resistant, resisting salt fog corrosion, and temperature classification can reach more than 180 ℃, and insulating properties are good.
