Embodiment Construction

[0024] The invention will be further illustrated by the following non-limiting examples.

[0025] Preparation method of coating:

[0026] Step 1, under the condition of avoiding sunlight or ultraviolet light irradiation, weigh each component in sequence according to the proportion;

[0027] Step 2: Mix the modified epoxy acrylate, modified urethane acrylate, and 70% acrylate reactive diluent evenly, keep the temperature of the mixed material lower than 50°C during the stirring process, and the stirring speed is 500-8000 rpm / min, last 5min;

[0028] Step 3: Put the remaining 30% acrylate active diluent and titanium dioxide into a high-speed disperser and mix them. During the mixing process, the material should be less than 50 degrees, and the stirring speed should be 800-1000 rpm. After 5 minutes, add additives , after stirring at 800-1000 rpm for 5 min, the prepared material was ground with a three-roll mill. To fineness below 10μm;

[0029] Step 4, put the white slurry p...

Abstract

The invention aims to provide white wood finishing paint cured under UV (ultraviolet)-LED (light-emitting diode) light sources and a preparation method of the finishing paint. The wood finishing paintis prepared from, in weight percent, 30-40% of modified epoxy acrylate, 10-20% of modified urethane acrylate, 30-40% of acrylate reactive diluents, 5-10% of photo-initiators, 0.4-1% of additives, 15-20% of titanium dioxide and 0.1-2% of fumed silica. The wood finishing paint has the advantages that the wood finishing paint can be rapidly cured under the UV-LED light sources and has good adhesiveforce and yellowing resistance when being used for wood ware, and the wood finishing paint solves the problems of slow curing, poor surface dry and easiness in yellowing of the light-cured white woodfinishing paint under the UV-LED light sources.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a white wood finish that can be cured by a UV-LED light source and a preparation method thereof. Background technique [0002] At present, most light-cured white wood paints are cured by conventional UV light sources. The conventional UV light source is a high-pressure mercury lamp, but the high-pressure mercury lamp consumes a lot of energy and generates a lot of heat. Compared with it, UV-LED light sources are energy-saving, environmentally friendly, and luminous. High, long life, fast response, less heat release and so on. At the same time, the Minamata Convention, which will come into force in 2020, clearly restricts the production and use of mercury lamps. With the rapid development of UV-LED (ultraviolet light-emitting diode) chip technology and its packaging technology, LED has huge market prospects in lighting and curing industries. All countries and regions...
