Abstract

The invention provides a UV top-coat paint, a preparation method and application thereof, and relates to the technical field of paint. The UV top-coat paint provided by the invention is prepared from the following components by weight: 15-30 parts of fatty acid modified epoxy acrylate, 8-15 parts of aliphatic polyurethane acrylate, 5-10 parts of thermoplastic acrylate, 30-60 parts of a functional monomer, 4-6 parts of a photoinitiator, 0.5-2 parts of a dispersing agent, 0.1-0.5 part of a defoaming agent, 0.2-0.6 part of a flatting agent and 8-15 parts of matting powder. The UV top-coat paint product prepared by adopting the technical scheme is high in leveling speed and curing efficiency, and the solid content is close to 100%; when being applied to a reciprocating spraying process, the UV top-coat paint is convenient and fast to use, the product can be effectively recycled, the material loss and the emission of harmful substances are reduced, and the increasingly stringent environmental protection requirement can be met.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a UV clear finish coating and a preparation method and application thereof. Background technique [0002] At present, the coating of wooden doors in wooden furniture is mainly based on the traditional air spray gun process, and most of the products used are traditional polyurethane coatings (referred to as PU topcoats). The characteristic of the spray gun spraying process is that a large amount of oil mist will diffuse into the air, the waste of paint is large, and the utilization rate is low. Moreover, due to the high VOC emission of PU paint, the pollution to the environment is great, and it does not meet the increasingly stringent environmental protection requirements. [0003] Light-curing paint (UV paint for short) is a green and environmentally friendly paint with almost zero VOC emissions, which meets environmental protection requirements. In addition, reciprocating spra...
