Embodiment
[0025] Embodiment effect, 720 hours salt spray resistance test of antirust paint, test method:
[0026] The national standard "GB / T1771 Determination of neutral salt spray resistance of paints and varnishes" is used to conduct the salt spray test of the coating.
[0027] The content of zinc phosphomolybdate is 10% of the embodiment 1. After 720 hours of salt spray test, the performance is better than the alkyd red lead antirust paint. The alkyd red lead antirust paint model produces corrosion bubbles, while the new antirust paint The samples were not corroded. Embodiment 2, embodiment 3 all paint films are intact, and the surface is intact.

Abstract
The invention provides an environment-friendly phosphomolybdate antirust paint, which is composed of the following components by weight percentage: 10% to 50% of alkyd or phenolic resin, 3% to 30% of phosphomolybdate antirust pigment, antirust 3% to 27% of rust pigment, 10% to 50% of filler, 0.2% to 1.0% of organic bentonite, 0.2% to 1.5% of auxiliary agent, 0.2% to 3% of metal desiccant, and 15% to 40% of solvent. The invention has better anti-rust effect, is environmentally friendly and practical, does not use red lead powder banned internationally, has better salt spray resistance than alkyd red lead anti-rust paint, has no irritating smell, is beneficial to the health of construction workers, and is an environmentally friendly , anti-rust paint that is non-toxic to the environment.
Description
technical field [0001] The invention relates to an environment-friendly antirust paint, which contains coated phosphomolybdate, in particular to a general-purpose environment-friendly antirust paint without lead oxide, which can be used for antirust treatment of steel structures . Background technique [0002] In traditional steel structure engineering, anti-rust paint is usually required for corrosion protection of steel substrates. At present, commonly used anti-rust paints include zinc powder anti-rust paint, iron red anti-rust paint, red lead anti-rust paint, etc., among which red Dan anti-rust paint has good anti-rust performance, but red lead, that is, three lead tetroxide is a heavy metal oxide, which has high toxicity, and there is a risk of heavy metal lead pollution to the environment during the paint construction and cleaning process, and it is harmful to the human body. There are hazards of lead poisoning and serious environmental pollution. It is the current de...
