Embodiment 1

[0025] Slowly add 50% zinc sulfate solution to 10% phytic acid and 7% tannic acid mixed aqueous solution, stir while adding, then adjust pH to 5-6 with caustic alkali or ammonia water, and continue stirring for 10 minutes to form Zinc phytate and zinc tannate, mix zinc phytate and zinc tannate with mica or micaceous iron oxide in a weight ratio of 2:3, stir for 60 minutes to make it evenly mixed, wash with water, dry and grind to a particle size of 0.5-4μm, to obtain antirust pigments containing zinc phytate, zinc tannate and mica or micaceous iron oxide.

Embodiment 2

[0027] Slowly add about 30% aluminum sulfate solution to 10%~20% phytic acid and 7%~10% tannic acid mixed aqueous solution, stir while adding, and then use caustic alkali or ammonia water to adjust the pH to 3.5~ 4.0, continue stirring for 16 minutes to generate aluminum phytate and aluminum tannate, then mix aluminum phytate and aluminum tannate with mica or mica iron oxide in a weight ratio of 1:6, and stir for 120 minutes to make it Mix evenly, wash with water, dry, and grind to a particle size of 0.5-4 μm to obtain an antirust pigment containing aluminum phytate, aluminum tannate, mica or mica iron oxide.

Embodiment 3

[0029] Slowly add 10% to 30% ferric chloride solution to 10% to 20% phytic acid and 5% to 10% tannic acid mixed aqueous solution, stir while adding, and then adjust the pH with caustic alkali or ammonia water =5, continue to stir for 10 minutes to generate iron phytate and iron tannate double salt, then mix iron phytate and iron tannate double salt with mica or micaceous iron oxide in a weight ratio of 1:1, after stirring After 200 minutes, make it evenly mixed, wash with water, dry, and grind to a particle size of 0.5-4 μm to obtain an antirust pigment containing iron phytate and iron tannate double salt and mica or micaceous iron oxide.

Abstract

The invention relates to an anti-corrosive pigment and a preparation method thereof, belonging to the technical field of chemical pigments. The anti-corrosive pigment contains phytate, tannate and mica or mica series stuffing / or mica ferric oxide or ferrophosphorus powder. The preparation method comprises the following steps: adding the mica or mica series stuffing / or mica ferric oxide or ferrophosphorus powder stuffing to the phytate and the tannate for mixing; and then adding a surface treating agent to the mixed liquid to carry out surface treatment, and then drying to obtain the anti-corrosive pigment the particle size of which is 0.5-4 mu m. The anti-corrosive pigment of the invention has good fusion property with other pigments, stuffing and resin (water-based and oil-based), and can be mixed at discretion. The anti-corrosive pigment has especially excellent anti-corrosive property and combination property, the price is lower than that of the current anti-corrosive pigments, andthe ratio of performance to price is high.

Description

technical field [0001] The invention belongs to the technical field of chemical pigments, in particular to an antirust pigment and a preparation method thereof. Background technique [0002] The coatings used to prevent metal corrosion are called anti-corrosion coatings, and the main anti-corrosion effect is anti-rust pigments. At present, anti-rust pigments are divided into toxic anti-rust pigments, low-toxic anti-rust pigments or non-toxic anti-rust pigments. Toxic anti-rust pigments mainly include lead series and chromates, low-toxic or non-toxic anti-rust pigments, such as zinc molybdate, barium metaborate, zinc phosphate, calcium zinc phosphomolybdate, aluminum tripolyphosphate, calcium exchanged silica , ferrite and their modified products and combined products, etc., their antirust performance is similar to that of toxic antirust pigments. In recent years, in terms of metal antirust, phytic acid has been used to replace chromic acid and phosphoric acid for metal sur...
