Aluminium pigment with high dispersion, corrosion inhibition, dual coating and water resistance

Abstract

The invention discloses an aluminium pigment with high dispersion, corrosion inhibition, dual coating and water resistance. The pigment is characterized in that the pigment is prepared by the following raw materials in parts by weight: 40-45 parts of sheet shaped aluminium powder, 100-110 parts of isopropanol, 0.3-0.35 parts of copper sulphate crystal, a proper amount of deionized water, 4-4.5 parts of phenolic ether phosphate ester, a proper amount of absolute ethanol, 9-10 parts of ethyl orthosilicate, 6-7 parts of triethoxyvinylsilane, 9-10 parts of ammonia water whose concentration is 20wt%, 200-220 parts of butyl acetate, 5-6 parts of acrylic acid, 5-6 parts of methacrylic acid, 0.6-0.65 parts of dibenzoyl peroxide, 13-15 parts of 1-methoxy-2-propanol, 1.5-2 parts of polyether polyester modified organosiloxane, 0.9-1.2 parts of guar gum, 0.4-0.6 parts of soya bean lecithin, 0.8-1 part of propyl gallate, 4-5 parts of mica powder, and 2-3 parts of titanium dioxide. The product is completely coated, and has good water resistance; the product can be uniformly dispersed in an aqueous system.

Description

technical field

[0001] The invention relates to the technical field of pigments, in particular to a high-dispersion corrosion-inhibiting double-coated water-resistant 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 used...
