Antibacterial-enhanced aqueous aluminum pigment with zinc oxide/silver compound powder

Abstract

The invention discloses an antibacterial-enhanced aqueous aluminum pigment with zinc oxide / silver compound powder. The antibacterial-enhanced aqueous aluminum pigment is characterized by being prepared from the following raw materials in parts by weight: 40 to 45 parts flaky aluminum powder, 100 to 110 parts of isopropyl alcohol, 0.3 to 0.35 part of copper sulfate crystal, a proper amount of deionized water, 4 to 4.5 parts of phenolic ether type phosphate, a proper amount of absolute ethyl alcohol, 9 to 10 parts of tetraethoxysilane, 6 to 7 parts of vinyltriethoxysilane, 9 to 10 parts of ammonia water with the weight concentration of 20 percent, 200 to 220 parts of butyl acetate, 5 to 6 parts of crylic 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 zirconium phosphate, 4 to 5 parts of nano-zinc oxide, 2 to 3 parts of carboxymethylcellulose, 0.8 to 1 part of sodium polyacrylate, 2 to 3 parts of glycerinum and 4 to 5 parts of a silver nitrate solution with the weight concentration of 10 percent. The product disclosed by the invention can be well dispersed in finished products such as an aqueous coating and ink, and is high in antibacterial property.

Description

technical field [0001] The invention relates to the technical field of pigments, in particular to a zinc oxide / silver composite powder antibacterial enhanced water-based aluminum pigment. 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 u...

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
