Steel surface rust conversion emulsion

Abstract

The invention discloses a steel surface rust conversion emulsion. The steel surface rust conversion emulsion is prepared from 48-55wt% of deionized water, 8-15wt% of aqueous emulsion, 20-28wt% of industrial phosphoric acid, 0.5-1wt% of triethanolamine borate, 2-5wt% of alumina, 4-7wt% of sulfamic acid, 1-3wt% of oxalic acid, 1.5-2.5wt% of citric acid, 1-2wt% of zinc chloride, 0.5-1.5wt% of manganese chloride, 2.5-5wt% of hexamethylene tetramine and 0.5-1.5wt% of sodium carboxymethyl cellulose. The steel surface rust conversion emulsion has the characteristic that 1, rust removal and prevention functions are obtained and adaptability is good, 2, a bonding force is good, the steel surface rust conversion emulsion can be combined with various types of paint, coatings and paste ash and does not produce dissolution problems such as wrinkling and bubbling and an antirust capability is improved by 30-50%, 3, energy saving, environmental protection, no pollution and no blind angle in construction, and labor and time saving are realized, and 4, the steel surface rust conversion emulsion is suitable for conversion of rust on the surfaces of various labeled steel and cast iron and realizes conversion of harmful rust into a film beneficial for steel surface corrosion resistance.

Description

technical field [0001] The invention belongs to metal surface rust removal and anticorrosion agent, in particular to a steel surface rust conversion emulsion. Background technique [0002] The huge economic losses caused by the rusting of metal (steel) surfaces in the world every year are immeasurable. According to statistics, the losses caused by corrosion account for 10%-20% of the world's total steel production. In my country, the annual losses caused by steel corrosion are as high as 15 billion RMB. Therefore, metal surface rust removal and anticorrosion treatment is a very important task. There are many methods for metal surface rust removal and anticorrosion treatment, the most commonly used method is to use metal surface rust and anticorrosion agent. Although the existing metal surface derusting and preservatives have certain effects on derusting and anticorrosion, there are still some deficiencies, mainly that the derusting is not thorough, the surface adhesion betw...

Problems solved by technology

Although the existing metal surface derusting and preservatives have certain effects on derusting and anticorrosion, there are still some deficiencies, mainly that the derusting is not thorough, the surface adhesion between the paint and the derusting is not strong, and it is easy to wrinkle and bulge. Bubbles, prone to secondary rust, resulting in low rust and corrosion resistance of metal (steel)
