Corrosion-resistant aqueous aluminum pigment with shielding effects

Abstract

The invention discloses corrosion-resistant aqueous aluminum pigment with shielding effects. The corrosion-resistant aqueous aluminum pigment is characterized by being prepared from the following raw materials in parts by weight: 40-45 parts of sliced aluminum powder, 100-110 parts of isopropanol, 0.3-0.35 part of copper sulfate crystals, an appropriate amount of deionized water, 4-4.5 parts of phenol ether phosphate, an appropriate amount of anhydrous ethanol, 9-10 parts of tetraethyl orthosilicate, 6-7 parts of vinyl triethoxysilane, 9-10 parts of an ammonia solution of which the concentration is 20wt%, 200-220 parts of n-butyl acetate, 5-6 parts of acyclic acid, 5-6 parts of methacrylic acid, 0.6-0.65 part of benzoyl peroxide, 13-15 parts of propylene glycol monomethyl ether, 2-3 parts of animal oleic acid, 3-4 parts of carbon fibers, 4-5 parts of 200-mesh spherical permalloy powder, 1.5-2 parts of stearic acid and 1-1.2 parts of polyvinyl alcohol. According to the corrosion-resistant aqueous aluminum pigment disclosed by the invention, the carbon fibers and the permalloy powder are added during preparation of products, so that the magnetic conduction rate of materials is reduced, the corrosion-resistant aqueous aluminum pigment can be added during preparation of shielding materials, and coating films are even.

Description

technical field [0001] The invention relates to the technical field of pigments, in particular to a corrosion-resistant water-based aluminum pigment with a shielding effect. 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...

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
