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 dual coated aqueous aluminum pigment for antifouling paint. The dual coated aqueous aluminum pigment is characterized by being prepared from the following raw materials in parts by weight:40 to 45 parts of flaky aluminum powder, 100 to 110 parts of isopropanol, 0.3 to 0.35 part of copper sulfate crystals, a proper amount of deionized water, 4 to 4.5 parts of phenol ether phosphate, a proper amount of absolute ethyl alcohol, 9 to 10 parts of ethyl orthosilicate, 6 to 7 parts of vinyltriethoxysilane, 9 to 10 parts of ammonium hydroxide with the concentration being 20 weight percent, 200 to 220 parts of butyl acetate, 5 to 6 parts of acrylic acid, 5 to 6 parts of methacrylic acid, 0.6 to 0.65 part of dibenzoyl peroxide, 13 to 15 parts of propylene glycol monomethyl ether, 2 to 3 parts of polyvinyl alcohol, 1.5 to 2 parts of fatty acid, 4 to 5 parts of anatase nanometer titanium dioxide, 1.5 to 2 parts of ferric oxide, 2 to 3 parts of carbon nanometer tube and 0.5 to 0.6 part of polyamide wax. The dual coated aqueous aluminum pigment can be used in the antifouling paint; the dust pollution is reduced; the self-cleaning antifouling efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of pigments, in particular to a double-coated water-based aluminum pigment that can be used for antifouling paints. 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 pigments used ...
