Abstract

The invention relates to environment-friendly water-based flicking type metal car refinishing paint and a preparing method thereof. The water-based paint is prepared from, by weight, 2 parts to 4 parts of polyester resin, 75 parts to 85 parts of intermediates, 0.5 part to 2 parts of cellulose acetate butyrate, 5 parts to 9 parts of pigment, 3 parts to 6 parts of deionized water, 1 part to 3.2 parts of solvents, 0 part to 1 part of amine, 0 part to 1 part of dispersing agents and 0 part to 1 part of flattening agents. Compared with the prior art, the paint and the preparing method have the advantages that flicking aluminum silver paste and pearls are used as the pigment, flicking strength is high, and high metal texture is achieved in the sun; as the dispersing agents, the flattening agents, thickening agents and the like synergistically act, the pigment is evenly dispersed, particle directional arrangement is good, system compatibility is good, storage is stable, VOC emission is low, and the paint and the preparing method are environmentally friendly and can be widely used for car refinishing.

Description

technical field [0001] The invention relates to fine chemical coatings, in particular to an environmentally friendly water-based flashing metal car repair paint and a preparation method thereof. Background technique [0002] With the continuous growth of domestic car ownership, the prosperity and development of the car refinish paint industry will be brought. There are more and more paints with metal effects such as pearls and aluminum powder on the car body, and metallic flash paint is the most important car refinish paint product. The country's environmental protection requirements are becoming increasingly stringent, and water-based or powder automotive coatings with low VOC emissions are bound to become the future development trend. Water-based aluminum powder is a special coated aluminum powder, which is difficult to disperse and very easy to agglomerate. Corresponding water-based dispersants and leveling aids have also been increasingly developed. Foreign refinish pai...
