Ultraviolet curable solid color coating

Abstract

The invention discloses an ultraviolet curable solid color coating, and belongs to the technical field of coatings. The ultraviolet curable solid color coating comprises 20-30% of linear macromolecular polyester acrylate, 20-30% of fatty acid modified epoxy acrylate, 25-35% of a UV reactive diluent, 3-5% of a photoinitiator, 0.3-0.5% of a dispersant, 5-15% of a pigment and 0.1-0.8% of a flow aid.According to the ultraviolet curable solid color coating provided by the invention, the distinctness of the sprayed coating is greatly improved, the problems that the distinctness of a traditional ultravioletcurable solid color coating is lower than that of a PU solid color coating and the traditional ultravioletcurable solid color coating cannot completely replace the PU solid color coating are solved; the components of the ultraviolet curable solid color coating of the invention have good compatibility; the adhesive force of a paint film is high; the surface of the applied coating is smooth;the problems of whitening, cracking, paint film falling and the like are avoided; the environment-friendly effect of the coating is realized; the curing speed of the coating is high; and energy is saved.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an ultraviolet light curing solid-color coating. Background technique [0002] UV-curable coating is an environmentally friendly and energy-saving coating developed in the 1960s. After coating, under the irradiation of ultraviolet light, it will cause polymerization and cross-linking reactions, making the liquid coating into a solid coating, that is, using ultraviolet light to to cure. With continuous research, the development of UV-curable coatings has been relatively perfect and has a wide range of applications. However, when UV-curable solid-color coatings are used for custom-made furniture coating, their bright image performance has not been comparable to PU coatings, which greatly restricts the promotion and use of UV-curable solid-color coatings on custom-made furniture. Contents of the invention [0003] In order to overcome the above-mentioned defects in ...

AI Technical Summary

Problems solved by technology

[0005] The beneficial effect of the present invention is that: the UV-curable solid-color coating provided by the present invention utilizes the low-shrinkage characteristics of linear macromolecular polyester acrylate by specifically selecting linear macromolecular polyester acrylate and fatty acid modified epoxy acrylate. , as well as the high plumpness and high gloss of linear macromolecular polyester acrylate and fatty acid modified epoxy acrylate, achieve excellent wetting and wrapping performance on the raw material titanium dioxide, improve the cleanliness of the coating surface, and then make the UV curing solid The sharpness of image after spraying of the color coating has been greatly improved, overcoming the problem that the traditional UV-curable solid-color coating is not as good as the PU solid-color coating, and cannot completely replace the use of PU solid-color coatings, and has broadened the application of UV-curable solid-color coatings field
