According to the zinc-plating sealing agent, a formula is reasonable, the preparation method is simple, and an obtained coating is bright and transparent in appearance, flat and smooth; the force of bonding between the coating and a base body is in zero level, and the coating is good in wear resistance and toughness; the coating is relatively good in corrosion resistance and an indoor hanging piece cannot be rusted for more than 1.5 years.
Description
Technical field
The present invention relates to galvanizing surface processing technology field, refer more particularly to a kind of zinc-plated encapsulant and preparation method thereof.
Background technology
The zinc-plated main corrosion protection coating as steel part, ranks first electroplating in amount of finish, except because of process unit relatively low, the zinc coating in steel part is anodic coating, while there is galvanic corrosion when making moist, zinc first corrodes and steel substrate is protected.But zinc this as amphoteric metal, neither acidproof not alkaline-resisting yet, in atmosphere, be easy to generate zinc subcarbonate erosion and even white mao of long hickie, lime.After zinc-plated, carry out again Passivation Treatment, can improve to some extent slushing oil, extend the time of zinc corrosion itself.Therefore will do unlimitedly Passivation Treatment after electro-galvanizing, but drying aging, remake sealing treatment after passivation again than not sealing after passivation, aging far better, but current used encapsulant effect is also not obvious, the appearance of coat unfairness of encapsulant, corrosion-resistant, abrasion resistant coatings and basal body binding force are poor.
