Abstract

The invention discloses an aqueous acrylic polyurethane aluminum powder paint, which is composed of a component A and a component B, wherein the component A is composed of, by weight, 35-45% of aqueous hydroxyl acrylic emulsion, 0.3-1% of a defoamer, 20-30% of deionized water, 0.3-1% of a wetting dispersant, 5-15% of a propylene glycol butyl ether, 6-8% of aqueous aluminum powder, 5-10% of an ethylene-vinyl acetate copolymer wax emulsion, 5-15% of water-dispersible cellulose ester solution, and 0.3-1% of a base material wetting agent; and the component B is an isocyanate curing agent. The weight ratio of the component A to the component B is 7-9:1. A paint film formed by the aqueous acrylic polyurethane aluminum powder paint is quick to dry, is glossy and has high brightness. Orientation of the aluminum powder is excellent.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a water-based acrylic polyurethane silver powder paint and a preparation method thereof. Background technique [0002] With the continuous development of society, people have higher and higher requirements for the performance and environmental protection of coatings. Silver powder paint is widely favored by people for its rich colors, excellent color flop effect, and elegant decorative effect. Especially, new energy buses that advocate the concept of environmental protection often use silver powder and metal effect coatings. Most of the silver powder paints used in the painting of energy buses are solvent-based paints. Generally, single-component silver powder paints are used and then sprayed with varnishes. The organic solvent content is high, which seriously pollutes the environment and endangers the health of personnel. [0003] Using two-component waterborne acrylic polyurethane silv...
