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 high-brightness and high-stability of corrosion-resistant water-based aluminum pigment, which is prepared from the following raw materials in parts by weight: 40 to 45 parts of flaky aluminum powder, 100 to 110 parts of isopropyl alcohol, 0.3 to 0.35 parts of copper sulfate crystal, an appropriate amount of deionized water, 4 to 4.5 parts of phenolic ether phosphate, an appropriate amount of absolute ethanol, 9 to 10 parts of ethyl orthosilicate, 6 to 7 parts of vinyl triethoxysilane, 9 to 10 parts of ammonia with concentration of 20wt%, 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, 1.2 to 1.5 parts of polyvinyl alcohol, 0.3 to 0.4 part of sodium polyacrylate, 6 to 7 parts of nano antimony tin oxide, 1.2 to1.4 parts of dimethyl silicone oil, and 0.8 to 1 part of polydimethylsiloxane. The product prepared by the invention is not corroded in an aqueous system and has strong stability.

Description

Technical field [0001] The invention relates to the technical field of pigments, in particular to a high-brightness, high-stability, corrosion-resistant water-based aluminum pigment. Background technique [0002] Aluminum pigment is one of the important metal pigments. Due to its unique aesthetic effect and anti-corrosion, it has been widely used in anti-corrosion coatings, industrial coatings, automotive coatings, architectural interior and exterior decoration coatings, household appliances coatings, printing inks and plastic processing industries in recent years. application. With the continuous improvement of people's awareness of environmental protection and the continuous improvement of government environmental regulations, traditional organic solvent-based coatings will inevitably be replaced by environmentally-friendly water-based coatings. Aluminum pigments used in water-based coatings and solvent-based coatings have different requirements: First, the surface of the pigm...
