Abstract

The invention relates to a brush-coating LED transparent primer, and a preparation method and application thereof, and belongs to the field of chemical coatings; the brush-coating LED transparent primer comprises the following components in parts by weight: 18-30 parts of amino acrylic resin, 30-20 parts of polyester acrylic resin, 3-5 parts of bifunctional aliphatic polyurethane acrylic resin, 0.3-1 part of a defoaming agent, 0.3-1 part of a dispersant, 25-40 parts of an acrylate monomer, 0.5-1 part of fumed silica, 5-15 parts of a photoinitiator, 3-5 parts of an acrylate monomer dissolved CAB solution, 0.5-1.5 parts of a polishing auxiliary agent, 0.05-0.15 part of a base material wetting agent, 0.05-0.15 part of a leveling agent and 0.1-0.3 part of an anti-settling auxiliary agent. Thepreparation method comprises the steps: stirring the amino acrylic resin, the polyester acrylic resin, the bifunctional aliphatic polyurethane acrylic resin, the defoaming agent, the dispersing agentand the photoinitiator; adding fumed silica and the polishing auxiliary agent for dispersion; and adding the rest raw materials and stirring at low speed. According to the invention, the problems of poor surface drying, easy sagging during brush-coating construction and the like caused by oxygen inhibition during brush-coating transparent primer curing are solved, and the environmental protectionproperty during painting is improved.

Description

technical field [0001] The invention belongs to the technical field of chemical coatings, and more specifically relates to a brush-coated LED transparent primer, a preparation method and an application. Background technique [0002] Traditional PU, PE, NC and other coatings have high VOC content, which will cause great harm to the human body during construction and pollute the environment to a certain extent, which has gradually been restricted by the national environmental protection policy. UV paint basically has no VOC release and is environmentally friendly. However, traditional UV paint is cured by high-pressure mercury lamps. When mercury lamps are used, ozone will be generated. In the near future, the use of high-pressure mercury lamps will also be restricted by relevant laws, while LED lamps Ozone is not produced, and higher pressure mercury lamps consume less energy, are easy to use, and generate less heat. In the prior art, brushing UV coatings are cured by high-p...
