Abstract

The invention discloses water-borne wood paint and a preparation method. The water-borne wood paint is prepared from, by weight, 60-80 parts of acrylic emulsion, 30-50 parts of polyurethane water-borne dispersion, 1-40 parts of padding and 0.1-10 parts of auxiliaries. Compared with the prior art, the water-borne wood paint has the advantages that the paint film hardness and the abrasion resistance are greatly improved, the abrasion resistance is close to the oil paint level, the ubiquitous problem that water paint defoaming is hard is solved, and the water-borne wood paint further has the advantages that the leveling property is good, the paint film is full and attractive, and construction is easy.

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. my country is a major producer of paint in the world, and it is also the largest producer and export...
