Abstract

The invention provides an UV (Ultra Violet) film-pressed yellowing-resistant topcoat gloss paint, comprising the following components by weight percent: 35%-45% of functional monomer, 17%-23% of polyurethane acrylate, 26%-40% of epoxy acrylic resin, 0.2-0.3% of defoamer, 0.4%-0.6% of flatting agent and 5%-7% of photoinitiator. The functional monomer is a mixture of hydroxyethyl methacrylate, dipropylene glycol diacrylate, tripropylene glycol diacrylate and trimethylolpropane triacrylate. The UV film-pressed yellowing-resistant topcoat gloss paint provided by the invention is good in adhesive force, excellent in resistance to yellowing, low cost, simple and flexible to operate, high in drying speed, free of waste and high in production efficiency.

Description

technical field [0001] The invention relates to a UV paint, in particular to a film-pressed glossy yellowing-resistant finish paint. Background technique [0002] Due to the advantages of high production efficiency, high utilization rate, and good fullness of the paint film, the UV coating process is widely used on flat panels such as bamboo and wood floors, PVC gussets, and furniture countertops. However, in actual operation, there will be problems such as screen jumping, pinholes, and air bubbles, resulting in a high rework rate, increasing production costs, and the construction conditions have high environmental requirements. In order to overcome these problems, the film pressing process is adopted in production. Although the production efficiency is slightly lower, the risk is lower and the surface effect of the paint film is better. Therefore need to provide a kind of UV film pressure resistant yellow bright finish coating. Contents of the invention [0003] The pur...
