Water-based UV aluminum powder paint and preparation method thereof

Abstract

The invention discloses water-based UV aluminum powder paint and a preparation method thereof. The water-based UV aluminum powder paint contains the following components by weight percent: 50%-60% of a 4-5 functional waterborne polyurethane acrylate dispersion body, 5%-10% of pentaerythritol triacrylate, 4%-5% of water-based aluminum-silver paste, 1%-5% of a photoinitiator, 1%-5% of a water-based EVA wax emulsion, 1%-5% of a water-based polyamide wax, 1%-2% of a wetting agent, 1%-2% of a dispersing agent, 5%-10% of an organic cosolvent, 10%-15% of pure water, 1%-2% of a rheological agent and 0.3%-0.5% of an ammonia neutralizer. According to the water-based UV aluminum powder paint and the preparation method, the disadvantages and deficiencies in the prior art are overcome, the VOC content of the UV aluminum powder paint is 100g / L-150g / L and is decreased by 70%-80% compared with that of the traditional solvent type aluminum powder paint; after a coating film is irradiated by virtue of ultraviolet light (for 10-20 seconds), a film can be formed through drying; after the coating film is dried, the directional alignment property of aluminum powder is good, the coating film has excellent physical and chemical properties, the production efficiency is high, the energy conservation and the emission reduction are realized, and the aluminum powder paint can pass relevant detection standards of cosmetic coatings.

Description

technical field [0001] The invention relates to a water-based UV aluminum powder paint and a preparation method thereof, belonging to the technical field of cosmetics. Background technique [0002] In the existing production process, heat-curing solvent-based aluminum powder paint is mostly used for cosmetic ABS substrates. The VOC (volatile organic compound) content of solvent-based aluminum powder paint is 450-600g / L, the organic solvent content is high, and the pollutant discharge is large. , lower production efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcoming and the deficiency that exist in the prior art, for achieving the above object, the first technical scheme that the present invention adopts is: a kind of water-based UV aluminum powder paint, comprises following component by weight percentage: 4 50-60% of 5-functional water-based polyurethane acrylate dispersion, 5-10% of pentaerythritol triacrylate,...
