Antirust paint

Abstract

The invention discloses antirust paint. The antirust paint comprises the following components by weight: 60-80 parts of inositol hexaphosphate, 40-50 parts of iron oxide red, 15-30 parts of aluminite powder, 5-10 parts of ethylene glycol, 20-40 parts of zinc yellow, 6-12 parts of 731 dispersing agent, 5-10 parts of barium sulfate, 14-20 parts of sodium nitrite composite corrosion inhibitor, the balance of water solvent. The antirust paint provided by the invention is free of pollution and low in cost.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an antirust paint. Background technique [0002] According to statistics, the direct economic loss caused by metal corrosion accounts for about 4% of the gross national product in my country every year. Therefore, the corrosion protection of metals has attracted more and more attention. In the previous metal anti-corrosion coating technology, the pretreatment of the metal surface before painting accounts for about 45% of the total price of the entire coating project. If the surface treatment processes such as rust removal, oil removal, and water removal can be reduced or omitted, the coating cost can be significantly reduced, and the painting process can be greatly simplified at the same time, thereby reducing labor intensity and reducing the harm of rust dust to the human body. At present, the solvent-based anti-rust paint with rust widely used in the industry is simple in constructio...

However, the formaldehyde, benzene, and xylene contained in the solvent-based rust-resistant anti-rust paint are all toxic carcinogens, which cause great hidden dangers to human health, and are far from meeting people's requirements for health and environmental protection.
