Abstract

The invention provides a high-adhesion dip-coating water-based color matching finish paint and a preparation method thereof. The water-based color matching finish paint comprises the following components in percentage by mass: 45-70% of water-based rheological high-adhesion emulsion, 5-32% of color paste, 0.1-3.0% of a wetting dispersant, 0.1-5.0% of matt powder, 0.5-3% of wax powder or wax emulsion, 1-6% of a coalescing agent, 0.3-5% of an anti-sagging agent, 0.2-2% of a thickener, 0.2-3% of a leveling agent, 0.2-2.0% of a basic material wetting agent, 0.5-1.5% of other auxiliaries, and 1-15%of water. The product disclosed by the invention meets the related requirements of GB / T 23999-2008, and is safe and environment-friendly; the color mixing requirements of different colors are met, the leveling property is good, and wear resistance and scratch resistance are achieved; VOC emission is reduced, production and manufacturing are easy, construction safety is improved, and harm to terminal consumers is reduced.

Description

technical field [0001] The invention belongs to the field of wood ware paints, and in particular relates to a high-adhesion dip-coating water-based color tone finish paint for wood decoration and a preparation method thereof. [0002] technical background [0003] The common coating methods of water-based paint are: dip coating, brush coating, roller coating, spray coating, etc. In the field that requires all-round coating, dip coating is a simple and effective coating method. According to different coating scenarios, different viscosities can be adjusted to meet the corresponding coating requirements. Dip coating is widely used in: metal (automobiles, containers, instruments, etc.), plastics (subway, home appliances, electromechanical, etc.), wood (office stationery, furniture, molds, etc.). [0004] At present, the traditional all-round coating process includes: 1. The combination of NC (nitro) high-solid pumping primer and NC dipping topcoat for the outer surface of the p...
