Problems solved by technology

[0004] At present, the products used in the market are basically products cured by mercury lamps, which have a certain degree of radiation, and must be well protected to have certain safety hazards.
At the same time, due to the relatively large energy consumption of the mercury lamp and the high temperature during the curing process, some workpieces will be deformed when they are exposed to high temperature after conventional UV coating and ultraviolet light irradiation.

Abstract

The invention provides an LED curing roller painting white primer, and belongs to the technical field of paint. The LED curing roller painting white primer is specifically composed of the following components: epoxy resin, polyester acrylic resin, amino resin, trimethylolpropane tripropionate, polyester acrylic resin, tripropylene glycol diacrylate, adhesive resin, defoamer, wetting dispersant, 2, 4, 6-trimethylbenzoyl-diphenyl, phenyl bis (2, 4, 6-trimethylbenzoyl) phosphine oxide, 2-isopropyl thioxanthone, zinc stearate, ground calcium carbonate, talcum powder, titanium dioxide, fumed silica, a photoinitiator and active amine. According to the invention, the curing speed and toughness can be enhanced, deep drying and surface drying can be realized, the overall drying and adhesion of the paint can be optimal, and the paint can be conveniently used for coating workpieces which are easy to deform at high temperature.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an LED curing roller coating white primer and a preparation method and application method thereof. Background technique [0002] With the strengthening of environmental protection awareness and the formulation of harsh environmental protection laws, starting from 2017, furniture companies used solvent-based paints and were shut down by the environmental protection department for rectification. The transformation and upgrading of furniture enterprises, in panel furniture enterprises, all use the UV roller coating process, which greatly improves the production effect. According to the survey, 80% of furniture companies have roller coating equipment, and 20% of them do not have equipment, and they are all outsourced to different degrees to have UV equipment for processing. Cutting and assembling processed UV slabs into various furniture is a mature trend of technology. The effect...
