Description

technical field

[0001] The invention relates to the technical field of coatings, in particular to a hyperbranched ultraviolet light curing coating and a preparation method thereof. Background technique

[0002] UV-curable coatings use ultraviolet light as the radiation curing light source, and the photoinitiator in the coating absorbs the ultraviolet light energy to form free radicals, thereby initiating the polymerization and cross-linking reaction of the resin and active monomers, so that the liquid coating film can be cured. This UV-curable coating does not require heating, and can quickly cure and form a film on flammable substrates such as paper, plastic, leather and wood. Therefore, compared with other types of coatings, it has the advantages of no pollution, fast curing speed, low curing temperature Low energy consumption, high production efficiency, low volatile matter, environmental protection and energy saving, excellent coating performance, etc., good friction res...
