High-tolerant UV environment-friendly clear varnish for Americian solid wooden cabinet

Abstract

The high-tolerant UV environment-friendly clear varnish for Americian solid wooden cabinet comprises base coat and finishing coat, which are used cooperatively; the base coat is prepared from the following materials by mass percent: 10 to 15 percent of modified acrylate, 30 to 35 percent of modified urethane acrylate, 30 to 40 percent of active monomer, 5 to 6 percent of photoinitiator, 10 to 15 percent of filler; the finishing coat is prepared from the following materials by mass percent: 15 to 20 percent of modified polyester acrylate, 25 to 35 percent of modified epoxy acrylate, 35 to 45 percent of active monomer, 4 to 6 percent of photoinitiator, 5 to 10 percent of extinction powder. Performing the full-process automated painting construction by virtue of spraying equipment, the chemical resistance lasts for 100 h, the thickness of dry film reaches 4.5 mil, the adhesive force reaches 4B, the brightness reaches 12 to 15 degrees, the scratch resistance test reaches 8 KG, no abnormalities in the washing-up liquid resistance test lasts for 24 h, no abnormalities of film in the water resistance test lasts for 24 h, the expansion on heating and contraction on cooling test and the thermocycling test pass, no abnormalities of film in the household chemicals resistance test exist.

Description

technical field [0001] The invention relates to the application technology of IPC classification C09D coating composition raw materials, especially the high-resistant UV spraying environment-friendly transparent varnish for American solid wood cabinets. 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; It is one o...
