Embodiment 1

[0008] Embodiment 1, a zinc-calcium fluorophosphate antirust powder, adds 800 purpose ultra-fine zinc powders to the phosphate that has been treated and purified, accounting for 0.5% of the total weight of the antirust powder; 0.8% by weight; potassium perfluorooctane sulfonate, tetraethylammonium perfluorooctane sulfonate, and ammonium perfluorooctane sulfonate account for 0.3‰ of the total weight of the antirust powder. The production method of anti-rust powder: first use the flotation method to remove the impurities of potassium oxide, magnesium oxide, sulfur and arsenic from the natural phosphate, so as to purify the phosphate; then add 800-1200 mesh ultra-fine zinc to the purified phosphate Powder, accounting for 0.5-20% of the total weight of the anti-rust powder; then adding nano-titanium hydride powder accounting for 0.8-28% of the total weight of the anti-rust powder, potassium perfluorooctane sulfonate, tetraethylammonium perfluorooctane sulfonate Salt and ammonium p...

Embodiment 2

[0009] Embodiment 2, a zinc calcium fluorophosphate antirust powder, in the treated and purified phosphate, add 1000 mesh ultrafine zinc powder, accounting for 10% of the total weight of the antirust powder; 14% by weight; potassium perfluorooctane sulfonate, tetraethylammonium perfluorooctane sulfonate, and ammonium perfluorooctane sulfonate account for 4‰ of the total weight of the antirust powder. The production method of anti-rust powder: first use the flotation method to remove the impurities of potassium oxide, magnesium oxide, sulfur and arsenic from the natural phosphate, so as to purify the phosphate; then add 800-1200 mesh ultra-fine zinc to the purified phosphate Powder, accounting for 0.5-20% of the total weight of the anti-rust powder; then adding nano-titanium hydride powder accounting for 0.8-28% of the total weight of the anti-rust powder, potassium perfluorooctane sulfonate, tetraethylammonium perfluorooctane sulfonate Salt and ammonium perfluorooctane sulfona...

Embodiment 3

[0010] Embodiment 3, a zinc calcium fluorophosphate antirust powder, in the treated and purified phosphate, add 1200 mesh ultrafine zinc powder, accounting for 20% of the total weight of the antirust powder; 28% by weight; potassium perfluorooctane sulfonate, tetraethylammonium perfluorooctane sulfonate, and ammonium perfluorooctane sulfonate account for 8‰ of the total weight of the antirust powder. The production method of anti-rust powder: first use the flotation method to remove the impurities of potassium oxide, magnesium oxide, sulfur and arsenic from the natural phosphate, so as to purify the phosphate; then add 800-1200 mesh ultra-fine zinc to the purified phosphate Powder, accounting for 0.5-20% of the total weight of the anti-rust powder; then adding nano-titanium hydride powder accounting for 0.8-28% of the total weight of the anti-rust powder, potassium perfluorooctane sulfonate, tetraethylammonium perfluorooctane sulfonate Salt and ammonium perfluorooctane sulfona...

Abstract

The invention relates to the technical field of coatings, and concretely relates to a calcium zinc fluorophosphates antirust powder. The antirust powder is obtained by adding 800-1200 mesh ultrafine zinc powder having an amount accounting for 0.5-20% of the total weight of the antirust powder into purified phosphate, adding nanometer titanium hydride powder having an amount accounting for 0.8-28% of the total weight of the antirust powder, and adding potassium perfluorooctanesulphonate, heptadecafluorooctanesulfonic acid tetraethylammonium salt and perfluorooctanesulfonic acid ammonium salt which account for 0.03-0.8% of the total weight of the antirust powder. The calcium zinc fluorophosphates antirust powder provided by the invention has the advantages of no pollution and high cost performance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to zinc calcium fluorophosphate antirust powder. Background technique [0002] Anti-rust powder is a water-soluble anti-rust product, vaporized VCI particles penetrate into every corner of the metal in a confined space, forming a molecular thick protective layer to prevent metal from rusting. 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 present invention is to provide a pollution-free, cost-effective zinc ...
