Abstract

The invention relates to spraying waterborne wood primer and a preparation method thereof. The spraying waterborne wood primer is prepared from the following components in parts by weight: emulsion, a waterborne multifunctional additive, a film-forming additive, a defoamer, a substrate wetter, an anti-freezer, a preservative, a thickener and water, wherein the emulsion is pure acrylate copolymer. The spraying waterborne wood primer prepared with the method can not only remove formaldehyde in artificial boards but also prevent release of formaldehyde.

Description

technical field [0001] The invention relates to a coating for architectural decoration, in particular to a sprayed water-based wood primer and a preparation method thereof. Background technique [0002] With the development of the economy and the improvement of living standards, people have higher and higher requirements for environmental protection and health, and pay more and more attention to the problem of smog pollution. The implementation and the tightening of environmental protection policies in various places, the stricter restrictions on solvent-based coatings in national policies, and the increasing calls for green environmental protection in the society, the coatings industry, which was once regarded as a high-pollution industry, naturally cannot escape the fate of transformation and upgrading. At the same time, environment-friendly coatings such as water-based paints have ushered in unprecedented opportunities for development. Many coating companies have joined t...
