Description

technical field [0001] The invention relates to the field of chemical coatings, in particular to a coating and a preparation method thereof. Background technique [0002] Traditional civil wood paints such as polyurethane paint and nitro paint are the mainstream products of wood paint because of their cheap price and convenient construction. However, these traditional wood paints will release a large amount of toxic and harmful solvents during and after painting. Free TDI, some also contain heavy metals, do not meet environmental protection requirements. The water-based wood paint has made a breakthrough in the environmental protection of the paint. It uses water as the medium and has the advantages of non-toxic, tasteless, pollution-free, tough, impact-resistant, wear-resistant, good leveling, excellent clarity, and easy to use. With the improvement of living standards and the deepening of awareness, people are increasingly pursuing a healthy life, and one of the requireme...
