Description
Technical Field
The invention relates to the technical field of coatings, in particular to a light-cured coating capable of preventing decolorization.
Background
The photo-curing coating is also called photosensitive coating, which is ultraviolet light as coating curing energy and is also called ultraviolet light curing coating. The film can be quickly solidified into a film on flammable substrates such as paper, plastics, leather, wood and the like without heating. It is mainly composed of photosensitive resin, photosensitizer (photoinitiator) and diluent, and some additives, such as heat stabilizer, are added at the same time, and pigment and filler are added when preparing colored paint. The photosensitive resin is generally a low molecular weight resin having an unsaturated bond, such as unsaturated polyester, acrylic oligomer; the photosensitizer is a compound which can easily absorb ultraviolet light to generate active free radicals, such as benzophenone and benzoin alkyl ether; the diluent is mainly used for reducing the viscosity of the coating and simultaneously participates in curing and film forming, namely the active diluent, such as styrene, acrylic ester and the like. The photocureable coating has the advantages of short curing time (a fraction of a second to a few minutes), low curing temperature and low volatile content, and is a new coating variety which saves energy and resources, is pollution-free and has high efficiency; the disadvantages are that the curing process of the free radical type photo-curing coating is inhibited by oxygen and the surface curing is poor. In recent years, ionic photocurable coatings have been developed. In the prior art, the photo-curable coating is easy to fade under the condition of wind and sun exposure, so that the color retention time is short, and therefore, there is room for improvement.
