Description

technical field [0001] The invention belongs to the technical field of paint production, and in particular relates to a non-toxic and environment-friendly water-based paint and a preparation method thereof. Background technique [0002] Water-based coatings are very popular because they can be well dispersed in water and no longer use organic solvents containing benzene, toluene, xylene, esters, etc. as diluents. Gradually attract people's attention. With the continuous development of my country's construction industry, people have put forward higher requirements for green buildings and urban image construction. As an important building material, high-performance water-based coatings are constantly improving in application performance. Under the condition of green economy, all countries in the world are developing environment-friendly water-based coatings to promote the development of green economy. From the analysis of usage, water-based coatings are more and more widely...
