Abstract

The invention discloses a quick-drying amino baking paint, the components of the quick-drying amino baking paint are as follows:alcoholic acid or acrylic acid resin, dispersing agent, pigment, anti-settling agent, polyhydric dibasic ester, 582-2 resin, leveling agent, dimethyl benzene and normal butyl alcohol. The invention also provides a preparation method of the quick-drying amino baking paint. The quick-drying amino baking paint of the invention is mainly applied in the miniature and thinner steel products such as the fan blade, the outer casing of an air-conditioner, the mechanical cover, the steel barrel and the antitheft door and the like. The quick-drying amino baking paint has the advantages that the baking paint is single componet, and after the baking paint being diluted by the thinning agent, the spraying construction can be directly performed, the construction is convenient, and the drying speed is quick; the paint has good decorative property, and can be made into a variety of pigment according to the requirements; the paint has good adhesive force, high gloss and smooth surface; the paint also has good gloss retention and color retention, more than 75 percent of gloss can commonly be retained after the paint is used outside for 3 years to 4 years by the user ; the preparation method is simple and easy to be realized; after being dried,the paint film is flat and bright.

Description
