Abstract
The invention discloses a polyamide resin capacitor aluminium shell film mulching paint and its preparation method. The polyamide resin capacitor aluminium shell film mulching paint is mainly prepared by mixing raw materials of a composition A and a composition B, wherein the composition A is composed of polyamide resin, ketone, polyethylene wax, nanometer powdered carbon, ethanol, glycerol and attapulgite; and the composition B is composed of an acrylic acid ester copolymer modifier, a silane coupling agent, graphite and tetramethylsilane. The formulation provided by the invention is reasonable and the preparation method is simple. The film mulching paint has a good curing effect on the capacitor aluminium shell and has heat-resistant and wear-resistant performance, and can be used to effectively protect the capacitor and increase the service life of the capacitor.
Description
Technical field
The present invention relates to capacitor case and chemical composition, be specifically related to a kind of polyamide resin capacitor aluminium shell film mulching paint and preparation method thereof.
Background technology
Progress along with the electron trade technology, the manufacturing technology of electronic circuit board also has greatly improved, for volume and the reduction of dwindling electronic product consumes, electrolytic condenser is as one of universal component on the electronic circuit board, it is more and more higher not only its heatproof, anti-puncture being required, and to require its footprints also be the smaller the better.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 in asking, damages and reduction of service life easily in the sky of compactness, traditional aluminium shell of capacitor is that subpunch is made shape, and one deck insulating material is sealed up in rear 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-air themperature of insulating material of heat-sealing is not high enough, also can produce a lot of plastic film waste materials in the process of heat-seal process.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, the method mainly is to take 1000～20000 volts high potential gradient, make gaseous ion bump teflon tetrafluoroethylene (polytetrafluoroethylene), clash into fluorine atom, simultaneous oxidation generates fluorine oxide, fluorine oxide namely 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, but exists the problem that temperature tolerance is poor, production cost is higher.
