Problems solved by technology

Although the method of adding inhibitors to the aluminum pigment system can inhibit the corrosion rate of aluminum, the corrosion inhibition effect is limited. Prolonged contact with water-based system coatings, inks, etc. will still cause certain corrosion to the aluminum pigments, reducing the metallic luster and at the same time There are security risks

Abstract

The invention discloses a corrosion-inhibiting aqueous aluminum pigment being used for an antistatic coating. The pigment is prepared from, by weight, 40-45 parts of sheet aluminum powder, 100-110 parts of isopropyl alcohol, 0.3-0.35 parts of copper sulfate crystal, a proper amount of deionized water, 4-4.5 phenolic-ether-type phosphate, a proper amount of anhydrous ethanol, 9-10 parts of tetraethoxysilane, 6-7 parts of vinyltriethoxysilane, 9-10 parts of ammonia water being 20 wt% in concentration, 200-220 parts of butyl acetate, 5-6 parts of acrylic acid, 5-6 parts of methylacrylic acid, 0.6-0.65 parts of dibenzoyl peroxide, 13-15 parts of propylene glycol monomethyl ether, 1.5-2 parts of polyethylene wax, 2-3 parts of gelatin, 2-3 parts of zinc oxide, 4-5 parts of tin oxide, 0.8-1 part of sodium tripolyphosphate, 0.3-0.4 parts PVP, and 0.2-0.3 parts of sodium dodecyl benzene sulfonate, The pigment has strong corrosion-inhibiting performance in water.

Description

technical field [0001] The invention relates to the technical field of pigments, in particular to a corrosion-inhibiting water-based aluminum pigment that can be used for antistatic coatings. Background technique [0002] Aluminum pigment is one of the important metal pigments. Because of its unique aesthetic effect and anti-corrosion properties, it has been widely used in anti-corrosion coatings, industrial coatings, automotive coatings, architectural interior and exterior decoration coatings, household appliance coatings, printing inks and plastic processing industries in recent years. application. With the continuous enhancement of people's awareness of environmental protection and the continuous improvement of government environmental protection regulations, traditional organic solvent-based coatings will inevitably be replaced by environmentally friendly water-based coatings. Aluminum pigments used in water-based coatings have different requirements from aluminum pigmen...
