Abstract

The invention provides rust-proof powder of calcium fluophosphate; the components have follwing weight percentages: the remainder of natural phosphate and fluorite, 2 weight percent to 8 weight percent of processed rectorite powder, and 0.5 weight percent to 3 weight percent of group nano material. The rust-proof powder has the advantages of the strongest anti-rust performance and the most stable performance; the rust-proof powder is the best anti-rust paint in the world. The invention has broad adaptability and can be used for various kinds of oily paint; the prepared aqueous paint can be stored for a long time with no stratification or corrosion; no additional corrosion inhibitor or anti-settling agent is needed; the invention not only suits the steel surface, but also suits the anti-rust paint for copper, aluminum and other metal surfaces.

Description

technical field [0001] The invention relates to the technical field of antirust pigments, in particular to calcium fluorophosphate antirust powder for improving the antirust ability of antirust paints. Background technique [0002] Anti-rust paint is a necessary anti-rust material for steel components, and there must be anti-rust ingredients in the anti-rust paint, that is, anti-rust pigments. Traditional antirust pigments include red lead powder, iron red powder, aluminum tripolyphosphate powder, zinc silicate, and chromate. Some of the above antirust pigments contain heavy metals, and some do not contain heavy metals. The composite iron-titanium powder that has appeared in recent years has some impurities in its carrier component (phosphate), which makes its antirust performance unstable. Therefore the domestic market is in urgent need of a novel antirust pigment with excellent antirust performance, stable quality, non-toxic and harmless, easy to use, and adaptable to oil...
