Composite Zinc Calcium Fluorophosphate Antirust Powder

Abstract

A composite zinc-calcium fluorophosphate antirust powder, characterized in that: a mixture of zinc phosphate and calcium phosphate is the remainder, 800-1200 mesh ultra-fine zinc powder accounts for 0.3-20% of the total weight of the anti-rust powder; the nano-calcium oxide used The powder material accounts for 0.5-25% of the total weight of the antirust powder; the fluorine surfactant accounts for 0.1‰~5‰ of the total weight of the antirust powder. Its advantages are: the strongest anti-rust ability, the most stable performance, environmental protection, high cost performance, wide adaptability, suitable for all kinds of solvent-based paints, easy to use, no sedimentation, no delamination, no floating color, can prepare various kinds of paint. It can be used to make all-environmental water-based anti-rust paint with excellent performance. The salt water resistance test lasts for more than 20 days. It is suitable for steel surface, also suitable for other non-ferrous metal surface and non-metal surface anticorrosion paint.

Description

technical field [0001] The invention relates to an antirust pigment for coatings, in particular to an antirust pigment-composite zinc calcium fluorophosphate antirust powder for improving the antirust ability of the antirust paint. Background technique [0002] Anti-rust paint is an economical anti-rust material that must be used for steel components, and anti-rust paint must have anti-rust pigments with anti-rust function. Traditional antirust pigments include red lead powder, iron red powder, aluminum tripolyphosphate powder, zinc phosphate, and chromate. Some of the above antirust pigments contain heavy metals, and some do not contain heavy metals. Due to the heavy metal content, it will pollute the environment and cause harm to the health of front-line production workers. These pigments are not cost-effective and do not meet the needs of the current industrial production development. Contents of the invention [0003] The purpose of the invention is to research a comp...
