Description
Technical field
The present invention relates to a kind of non orientating silicon steel coating and application thereof, be specifically related to a kind of for non orientating silicon steel organic and inorganic environment-friendly type insulated dope and application thereof, make it form anti-corrosion insulation coating, for silicon steel insulating coating preparing technical field.
Background technology
Non orientating silicon steel is mainly used as the iron core material for generator of various electric motor, transformer and most household electrical appliance; in order to reduce silicon steel sheet eddy losses; ensure that there is higher resistivity on non orientating silicon steel surface; interlayer power loss is dropped to minimum; protect silicon steel to corrode from various corrosive medium simultaneously, therefore need in silicon steel top layer coating insulating corrosion coating.
At present, non orientating silicon steel coating mainly contains three kinds: organic coating, inorganic coating, organic and inorganic coating (half inorganic coating).Total development trend is that organic coating is eliminated gradually, and inorganic coating will replace inorganic coating gradually.But by the restriction of each side condition and the attribute of inorganic coating itself, what application was more at present is still half inorganic coating.Meanwhile, be subject to the requirement of environmental protection, progressively will replace Chromium coating without chromiumcoating.
Inorganic/organic phosphate insulating coating that patent US4496399 relates to one, this patent describes a kind of aqueous composition for applying non orientating silicon steel, the inorganic part of composition comprises 100 parts of aluminium phosphate magnesiums or 33 ~ 250 parts of colloid silicas and 10 ~ 25 parts of chromic anhydrides, or a kind of pure aluminium silicate particulate of 30 ~ 250 parts.The organic moiety of composition contains a kind of aqueous suspension solution of 15 ~ 1350 parts.Suspension contains a kind of vinylformic acid of 40 ~ 60% or the solid of vinyl acetate resin.
