The organic-inorganic laminating coating has a reasonable formula, a simple preparation method and a good curing effect on the aluminum capacitor shell; a capacitor is protected effectively; and the obtained laminating coating has heat resistance performance and wear resistance performance, and contributes to prolonging the service life of the capacitor.
Description
Technical field
The present invention relates to capacitor case and chemical compsn, be specifically related to a kind of organic-inorganic capacitor aluminum housing coating paint and preparation method thereof.
Background technology
Along with the electron trade development of technology; The manufacturing technology of electronic circuit board also has greatly improved; For the volume that dwindles electronic product consumes with reducing; Electrolytic condenser is as one of universal component on the electronic circuit board, and it is increasingly high not only its heatproof, anti-puncture being required, and to require its footprints also be more little good more.The electrolytic condenser footprints is little, at first is that aluminium shell of capacitor will have high length-to-diameter ratio, and electrical condenser diameter reduced dimension area is just little; Next is that capacitor case will have high air heat resistance; Otherwise, damages and reduction of service life easily in the sky of compactness in asking; Traditional aluminium shell of capacitor is that subpunch is processed shape, and one deck insulating material is sealed up in back pyrocondensation, and insulating material tightly is rolled on the capacitor case after heating.This its shortcoming of red shortness's plastic film electrical condenser is that the anti-AT of insulating material of heat-sealing is not high enough, in the process of heat-seal process, also can produce a lot of plastic film waste materials.The coating method that the disclosed a kind of insulation film on aluminum body of electrolytic capacitor of TaiWan, China Yabo Company is also arranged; Chinese invention patent application publication number CNl944704; This method mainly is to take 1000～20000 volts high potential gradient; Make gaseous ion bump ZX 21 tetrafluoroethylene (polytetrafluoroethylene), clash into fluorine atom, simultaneous oxidation generates fluorine oxide; Fluorine oxide promptly can produce powerful tackiness under high temperature action, and is deposited on the aluminum enclosure surface glutinous covering and forms the insulated hull rete of fluorine oxide.This method in fact only is the chloride secondary pollution of covering material that has reduced, and temperature tolerance is poor, the production cost problem of higher but exist.
