Abstract
The invention discloses an ultraviolet-curable solid-color coating, belonging to the technical field of coatings. The ultraviolet-curable solid-color coating comprises, in percentage by weight, 20-30% of linear macromolecular polyester acrylate and 20-30% of fatty acid. Modified epoxy acrylate, 25-35% UV reactive diluent, 3-5% photoinitiator, 0.3-0.5% dispersant, 5-15% pigment and 0.1-0.8% flow aid. The UV-curable solid-color paint provided by the invention greatly improves the distinctness of image after spraying, overcomes the problem that the distinctness of the traditional UV-curable solid-color paint is inferior to that of the PU solid-color paint, and cannot completely replace the use of the PU solid-color paint, and The components have good compatibility with each other, high paint film adhesion, smooth surface after coating, no whitening, cracking, paint film peeling and other problems, and is environmentally friendly, fast curing, and energy saving.
Description
technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an ultraviolet light-cured solid-color coating. Background technique [0002] UV-curable coating is an environmentally friendly and energy-saving coating developed in the 1960s. After coating, under UV light irradiation, polymerization and cross-linking reactions are caused to turn the liquid coating into a solid coating, that is, using ultraviolet light. to cure. With the continuous research, the development of UV-curable coatings has been relatively complete and has a wide range of applications. However, when UV-curable solid-color coatings are used for custom furniture painting, their distinctness of image has never been comparable to that of PU coatings, which greatly limits the promotion and use of UV-curable solid-color coatings on custom furniture. SUMMARY OF THE INVENTION [0003] In order to overcome the above-mentioned defects of the prior art, the tech...
