The present invention provides a kind of antirusting paints and preparation method for metal product.Capsule material is sprayed after boric acid is mixed with the natural attapulgite of nanometer, obtains microcapsules, is then added in epoxidized soybean oil, water and polyvinyl alcohol and is uniformly dispersed, antirust agent, film forming accelerating is added, be uniformly mixed, the antirusting paint for metal product is made.This method boric acid sprays capsule material after being mixed with the natural attapulgite of nanometer, capsule material is paraffin, when use, by applying coating after surface of metal product, 30min, freezing film, then it is roasting to carry out electricity, paraffin capsule material ruptures, and boric acid is reacted with polyvinyl alcohol to be formed cross-linked network and envelope and have the hydrogen bond formed between nano-attapulgite and polyvinyl alcohol, the two generates significant synergistic effect, the heat resistance of gained antirust coating is good, has a wide range of application, and has good rust-preventing characteristic. |
