Abstract

The invention provides waterborne wood paint, which comprises the following components in percentage by weight: 72 to 88 percent of polyurethane waterborne dispersion, 5 to 10 percent of water, 0.20 to 0.80 percent of dispersant, 0.20 to 0.80 percent of wetting agent, 0.10 to 0.60 percent of leveling agent, 0.20 to 0.80 percent of defoamer, 2 to 5 percent of nanometer silicon carbide, 1 to 4 percent of polyethylene waterborne wax liquid, 0.10 to 0.50 percent of fungicide, 0.5 to 3 percent of thickener, 2 to 6 percent of film-forming additive and 0.10 to 0.50 percent of pH regulator. The invention also provides a method for preparing the waterborne wood paint. In contrast to the prior art, the paint has the advantages that paint film hardness and wear resistance are greatly improved, and the wear resistance is close to the level of oil paint, so that the common problem that waterborne paint is difficult to defoam is solved. The paint also has the characteristics of good leveling property, plump attractive paint film, easy construction and the like.

Description

technical field [0001] The invention relates to a water-based paint, in particular to a water-based wood paint which is dried at normal temperature and used on the surface of wooden products, and has high hardness and high wear resistance. Background technique [0002] Environmental protection and energy are two major challenges we face in the 21st century. In order to meet this challenge, the coatings industry is gradually shifting from traditional varieties with high pollution, high energy consumption, and extreme dependence on petroleum industry products to environmentally friendly and resource-saving products such as water-based coatings, radiation-cured coatings, powder coatings, and high-solid content coatings. . The increasingly stringent laws and regulations in various countries have accelerated the pace of replacing solvent-based coatings with water-based coatings. [0003] my country is a major producer of paint in the world, and it is also the largest producer a...
