High-adhesion UV (ultraviolet) environment-friendly spraying white primer without sanding and recoating for woodware

Abstract

The invention discloses high-adhesion UV (ultraviolet) environment-friendly spraying white primer without sanding and recoating for woodware. The high-adhesion UV environment-friendly spraying white primer is prepared from the following raw materials in parts by mass: 10 to 15% of pure acrylic ester, 25 to 30% of modified epoxy acrylate, 20 to 25% of active monomer, 4 to 6% of photoinitiator, 0 to1% of dispersing agent, 0 to 1% of defoaming agent, 15 to 20% of R-706, 10 to 15% of 1250-mesh talcum powder and 0 to 1% of flatting agent. According to the invention, a coating formula is improved,the film hardness and fullness is increased, the polyester resin and acrylic monomers are polymerized together through the double bond of unsaturated polyester, thus the effect of modifying the acrylic resin is realized, the brittleness of the acrylic resin is improved by the flexibility of the polyester resin, the recoatability is obvious, the preparation and use are safe and environmentally friendly. Furthermore, the stereoscopic effect of a film is high, the handfeeling is smooth, the fullness of the white primer can be increased, excellent visual effect and touch feeling are obtained, theaesthetic degree of a product is greatly improved and the protection capability of the product is enhanced.

Description

technical field [0001] The invention relates to the application technology of the IPC classification C09D coating composition raw material, especially the high adhesion UV environmental protection spray white primer for woodware that can be recoated without sanding. Background technique [0002] UV paint is ultraviolet photocurable paint, also known as photoinitiated paint and photocured paint. It is automatically rolled and showered onto the surface of the furniture board by machinery and equipment. Under the irradiation of ultraviolet light, the initiator is decomposed, free radicals are generated, the resin is reacted, and the resin is instantly cured to form a film. It is currently the most environmentally friendly paint. UV paint is a widely used furniture paint. Its main features are as follows: After strong ultraviolet light curing treatment, the color is stable and long-lasting, which can effectively solve the problem of fading and color difference of the door panel;...

Problems solved by technology

[0008] During the construction of the above-mentioned improved coatings, the existing primer must be polished before it can be reapplied or varnished, and during the construction and polishing process, there will be traces on the surface of the paint film, which brings a lot to the fullness of the paint film. Large impact, thus affecting the fullness and the aesthetics of the furniture, the polishing process will cost extra manpower hours, reducing the construction efficiency, these shortcomings restrict the production efficiency and the coating effect of the product

More importantly, these paint products must be sanded when repainted, and the adhesion is limited. The recoating construction efficiency is low, the area is large, and the environmental protection is poor. The entire paint surface is dull, stiff and lacks aesthetic feeling.
