Description

Technical field [0001] The invention relates to the technical field of coatings, in particular to a green environmental protection UV coating and a preparation method thereof. Background technique [0002] In recent years, with the continuous improvement of living standards and the continuous progress of science and technology, people’s desire to improve their own living environment has become more and more urgent, and the performance requirements of decoration materials have become higher and higher. As one of the common home decoration materials First, the paint is even more so, not only requires it to have a comfortable and beautiful visual effect, but also requires its use is safe and environmentally friendly, and has good durability. [0003] At present, the widely used paints are solvent-based paints. Most of these paints use organic substances as solvents, and a large number of volatile organic substances can cause serious environmental pollution. It is under this situation...
