Abstract

The invention discloses a waterborne aluminum powder paint and a preparation method thereof. The waterborne aluminum powder paint comprises a part A and a part B, wherein the part A is prepared from the following components in parts by weight: 50-90 parts of waterborne polyurethane emulsion, 0.1-5 parts of a wetting agent, 0.01-1 part of a leveling agent, 0.02-2 parts of a de-foaming agent, 20-45 parts of an arrangement additive, 0.1-5 parts of a neutralizing agent, 1-10 parts of a film-forming additive and 5-20 parts of water; the part B is prepared from the following components in parts by weight: 1-10 parts of waterborne aluminum powder, 1-10 parts of a film-forming additive and 0.1-3 parts of a dispersing agent. The waterborne aluminum powder paint provided by the invention is excellent in arrangement of aluminum powder, anti-settling effect, water resistance and stability, and suitable for use on ABS / PC and other plastic substrates.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a water-based aluminum powder paint and a preparation method thereof. Background technique [0002] With the continuous improvement of people's awareness of environmental protection and the increasingly stringent environmental protection regulations, water-based coatings will become the leading role in the coatings market, and currently have a huge market in China. As a part of water-based paint, water-based aluminum powder paint is an environmentally friendly product that is replaced by solvent-based metal paint. Its research and development will open up an environmentally friendly road for the production of Chinese paint. [0003] Due to its low VOC content, water-based aluminum powder paint reduces VOC emissions during the coating process, which is beneficial to environmental protection. Water-based aluminum powder paint is non-toxic, tasteless, non-polluting, flame-retarda...
