High-transparency clear primer and preparation method thereof

Abstract

The invention discloses a high-transparency clear primer. The clear primer is composed of a water-based emulsion and an auxiliary agent, wherein the water-based emulsion is polyurethane, and the mass fraction of the water-based emulsion in the clear primer is 83-85 percent; the auxiliary agent is prepared from the following components in percentage by mass in the clear primer: 0.3 to 0.5 percent of substrate wetting agent, 0.4 to 0.5 percent of defoaming agent, 0.4 to 0.5 percent of flatting agent, 0.4 to 0.5 percent of thickening agent and 13 to 16 percent of deionized water. The prepared high-transparency clear primer is coated on the surface of office furniture or solid wood furniture to form a coating which is high in drying speed, extremely high in transparency, easy to polish and environment-friendly, and when the clear primer is matched with finish paint for use, the clear primer is high in transparency and good in fullness and has extremely high market application and popularization value.

Description

technical field [0001] The invention relates to the technical field of water-based industrial coatings, in particular to a clear primer with high transparency and a preparation method thereof. Background technique [0002] At present, the environmentally friendly furniture paint with the highest recognition in the market is water-based paint, because water-based wood paint uses water instead of organic solvents, which not only significantly reduces the VOC content, but also water-soluble paint, non-toxic and environmentally friendly, does not contain harmful solvents such as benzene, and does not Contains free TDI, so it is favored by consumers. [0003] In addition, although the environmentally friendly paint film formed after the existing water-based wood paint is solidified and cooled will not deepen the color of the wood, and the feel and fullness can also be compared with traditional paints, but its hardness is low, and transparency and good polishing cannot be taken in...

[0003] In addition, although the environmentally friendly paint film formed after the existing water-based wood paint is solidified and cooled will not deepen the color of the wood, and the feel and fullness can also be compared with traditional paints, but its hardness is low, and transparency and good polishing cannot be taken into account at the same time. properties, thus restricting the development and application prospects of water-based paint
