Embodiment 1
[0008] A metal anti-corrosion coating is prepared by stirring the following raw materials according to the weight ratio: 100-110 parts of epoxy resin, 20-30 parts of benzoic acid resin, 10-15 parts of diphenyl ether resin, 15-18 parts of xylene, 15-25 parts of cerium oxide, 6-10 parts of n-butanol, 8-12 parts of polybenzimidazole, 10-12 parts of KH-550, 10-15 parts of talcum powder, 3-8 parts of dimethylethanolamine, 6- 10 parts barium dinonylnaphthalenesulfonate and 50-60 parts water. Test the coating performance of this embodiment. The results are as follows: 2000h scratch salt test: no air bubbles, no shedding, 1mm rust spread at the scratch; 5000h salt spray test: no blistering, no shedding, no rust; Adhesion / MPa GB / T5210-2006: 11.3-14.4 .

The invention discloses a metal anticorrosive paint which is prepared by stirring the following raw materials in parts by weight: 100-110 parts of epoxy resin, 20-30 parts of benzoic acid resin, 10-15 parts of diphenyl ether resin, 15-18 parts of dimethylbenzene, 15-25 parts of cerium oxide, 6-10 parts of n-butanol, 8-12 parts of polybenzimidazole, 10-12 parts of KH-550, 10-15 parts of talcum powder, 3-8 parts of dimethylethanolamine, 6-10 parts of barium dinonylnaphthalene sulfonate and 50-60 parts of water. The commercial test proves that the prepared paint has the advantages of excellent water resistance and excellent corrosion resistance, can implement passivation and corrosion inhibition of the metal substrate, avoids using chrome and other heavy metals possibly causing environmental pollution, is simple to prepare and low in cost, and can be easily put into industrial production.
Description
technical field [0001] The invention relates to a metal anticorrosion coating, which belongs to the technical field of chemical coatings. technical background [0002] At present, the annual economic losses caused by metal corrosion in my country account for about 3-5% of the gross national product, and the losses exceed the sum of the losses caused by fire, wind disasters and earthquakes. For a long time, in order to reduce the loss of corrosion, people have taken many measures, such as electrochemical protection of metals, corrosive medium treatment, overlay protection and so on. But so far the most common, economical and practical protection measures are coating protection. Coating anti-corrosion is widely used because of its simple construction, economical applicability, no constraints on equipment area and shape, and certain decorative effects. [0003] At present, most of the anti-corrosion coatings applied on the surface of steel on the market are solvent-based coati...
