A dual cure scratch and abrasion resistant waterborne black gloss finish

Abstract

The invention discloses a dual-cured scratch-resistant wear-resistant water-based black luster finish coat which is prepared from the following components in parts by weight: 70-80 parts of aliphatic PUV (polyurethane acrylate), 0.1-0.2 part of pH regulator, 0.3-0.5 part of substrate wetting agent, 0.3-0.5 part of defoamer, 0.2-0.4 part of dispersing agent, 8-10 parts of water-based black paste, 1-1.5 parts of photoinitiator 1, 1-1.5 parts of photoinitiator 2, 0.1-0.2 part of leveling agent, 1-3 parts of film-forming assistant, 0.3-0.5 part of antifoamer, 0.1-0.3 part of wetting and anti-shrinkage agent, 0.6-1.0 part of thickener, 0.1-0.2 part of anti-settling agent, 0.5-1.0 part of scratch-resistant wear-resistant agent, 1-3 parts of wax dispersion, 0.1-0.2 part of anticorrosive bactericide, 0.1-0.2 part of moldproof algaecide and 1-8 parts of water. The black luster finish coat disclosed by the invention is prepared from dual-cured aliphatic PUV, has excellent scratch resistance and wear resistance, and has both the environment-friendly property of the water-based wood paint and the high drying and curing speed and excellent paint film mechanical properties of the oil-based UV paint. The invention is a favorable substitute for both the oil-based UV solid color paint and the water-based single-component solid color paint.

Description

technical field [0001] The invention relates to a water-based black varnish, in particular to a scratch-resistant and wear-resistant water-based black varnish with dual curing mechanisms (that is, light curing and self-crosslinking curing at room temperature). Background technique [0002] In the 21st century, oil-based UV wood paint has made great progress, and its advantages of fast curing, low pollution and energy saving have been applied in many fields. However, oily UV volatile monomers and initiators will bring irritating odors. At the same time, it is difficult to cure non-planar components due to the characteristics of light-cured Bunsen, and it is difficult to cure solid color paint systems such as black and white. A series of shortcomings and deficiencies seriously limit its use. In addition, the water-based wood paints in the prior art generally have low solid content in construction, and the fullness, scratch and wear resistance, hardness and anti-blocking prope...

However, oily UV volatile monomers and initiators will bring irritating odors. At the same time, it is difficult to cure non-planar components due to the characteristics of light-cured Bunsen, and it is difficult to cure solid color paint systems such as black and white. A series of shortcomings and deficiencies seriously limit its use

In addition, the existing water-based wood paints generally have low solid content in construction, and the fullness, scratch resistance, hardness and anti-blocking properties are not good enough, and there is still room for further improvement.
