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 water-resistant aluminum pigment with high magnetism. The water-resistant aluminum pigment is prepared from the following raw materials in parts by weight: 40-45 parts of flaky 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 phenolic ether phosphate ester, a proper amount of absolute ethyl alcohol, 9-10 parts of ethyl orthosilicate, 6-7 parts of vinyltriethoxysilane, 9-10 parts of ammonia water of which the concentration is 20 percent by weight, 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, 1-1.5 parts of ethylene-vinyl acetate wax, 2-3 parts of dimethyl silicone oil, 0.8-1 part of carboxymethylcellulose, 6-7 parts of ferrous sulfate, 3-4 parts of anhydrous sodium acetate, 4-5 parts of sodium hydroxide solution of which the concentration is 10 percent by weight, 3-4 parts of citric acid and 0.3-0.5 part of sodium dodecyl sulfate. The water-resistant aluminum pigment can be applied to magnetic printing ink.

Description

technical field [0001] The invention relates to the technical field of pigments, in particular to a water-resistant aluminum pigment with good magnetic properties. 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 in solvent-based coa...
