Abstract

The invention relates to a metal antirust paint, belonging to the technical field of paints. The metal antirust paint is prepared from the following substances in parts by weight: 40-50 parts of water-based acrylic acid modified epoxy resin, 5-10 parts of benzotriazole, 4-9 parts of polyorganosiloxane, 5-12 parts of ferricyanate, 6-15 parts of styrene, 8-15 parts of aluminum powder, 0.5-1.5 parts of nano silver with the particle size of 20-25nm, 30-40 parts of nano egg-shell meal with the particle size of 30-40nm, 6-9 parts of aluminum tripolyphosphate, 2-5 parts of tetraethylamine tetrafluoborate, 3-7 parts of talcum powder, 5-10 parts of iron oxide pigment slurry and 20-30 parts of water. The metal antirust paint is reasonable in component proportioning. The coating has the advantages of compact texture, low temperature resistance, favorable adhesiveness, favorable waterproof effect, corrosion resistance, discoloration resistance, wear resistance, favorable punching performance and favorable antimicrobial effect.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a metal antirust coating. Background technique [0002] Metal coatings are coatings with a metallic texture. Most of them require some form of pretreatment on the metal surface to improve the surface condition, so as to improve the adhesion of the coating and enhance the anti-corrosion protection effect on the metal substrate. Similar to traditional paint coating, before metal coating, some form of pretreatment is required on the metal surface to improve the surface condition, so as to improve the adhesion of the coating and enhance the anti-corrosion protection effect on the metal substrate. Existing metal materials have the problem of easy corrosion, and the surface is easy to be stained, which affects the appearance; it needs to be protected by coating, and the existing metal coatings have general corrosion resistance, which cannot meet the market demand for metal coatings. ...
