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 an anticorrosion waterborne aluminum pigment for reinforcing UV reflection ability. The pigment is prepared from the following raw materials by weigh: 40-45 parts of flake aluminum powder, 100-110 parts of isopropanol, 0.3-0.35 part of copper sulfate crystal, a proper amount of deionized water, 4-4.5 parts of phenol ether-type phosphate ester, a proepr amount of absolute ethyl alcohol, 9-10 parts of ethyl orthosilicate, 6-7 parts of ethylsiloxane, 9-10 parts of ammonia with concentration of 20wt%, 200-220 parts of butyl acetate, 5-6 parts of acrylic acid, 5-6 parts of methacrylic acid, 0.6-0.65 part of dibenzoyl peroxide, 13-15 parts of propylene glycol monomethyl ether, 0.5-0.6 part of lignocellulose, 0.7-0.8 part of polyethylene pyrrolidone, 4-5 parts of cordierite powder, 3-4 parts of far infrared ceramic powder, 3-4 parts of urea aqueous solution with concentration of 20wt%, and 1.5-2 parts of poly olefin wax. The product has high ultraviolet reflectivity.

Description

technical field [0001] The invention relates to the technical field of pigments, in particular to a corrosion-inhibiting water-based aluminum pigment with enhanced ultraviolet reflection ability. 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 pi...
