Embodiment 1

[0028] Under normal temperature and pressure, each component is selected according to the components and contents specified in "Example 1" in Table 1, and prepared according to the following method: Step 1, trifunctional aliphatic urethane acrylate resin, hexafunctional aliphatic Add urethane acrylate resin, hydroxyethyl methacrylate, trimethylolpropane triacrylate, 1,6-hexanediol diacrylate, and photoinitiator into the container, and rotate to disperse for 3-5 minutes until uniform; step 2, Add dispersant, leveling agent and defoamer to the mixture obtained in step 1 while stirring, rotate and disperse for 15-20 minutes until the fineness is less than or equal to 10 μm, and filter with 200 mesh filter cloth to obtain the laser roller for woodware Apply a glossy top coat. In the first step, disperse at a rotational speed of 500-800 RPM (rev / min); in step 2, disperse at a rotational speed of 1000-1200 RPM (rev / min).

[0029] The conventional performance test results and test r...

Abstract

The invention discloses laser roller-coating vanish paint for woodware. The laser roller-coating vanish paint for woodware is characterized in that the composition is prepared from the following components in percentage by weight: 50-58% of tri-functional aliphatic polyurethane acrylate resin, 10-13% of hexa-functional aliphatic polyurethane acrylate resin, 5-8% of hydroxyethyl methylacrylate, 5-8% of trimethylolpropane triacrylate, 16-20% of 1,6-hexanediol diacrylate, 4-6% of a photoinitiator, and 0.4-0.7 part of an assistant, wherein the assistant consists of 0.2-0.3% of a flatting agent, 0.1-0.2% of a dispersing agent and 0.1-0.2% of a defoaming agent based on the weight of the paint. The laser roller-coating vanish paint for woodware disclosed by the invention has good construction performance and extremely good mirror effect in a constructed film, and has characteristics of good adhesion, high hardness, high wear resistance, high glossiness (over 96 degrees), no roller scratchers, scratching resistance, good yellowing resistance, no smell, good hand feeling, and the like.

Description

technical field [0001] The invention relates to an ultraviolet light clear finish paint applied to woodware, in particular to a laser roller bright clear finish paint. Background technique [0002] At present, the roller coating methods commonly used in the field of UV wood paints are coated with ordinary rubber rollers or silica gel rollers with smooth surfaces. This method has a small amount of one-time coating, and the average coating amount is 10-20g / ㎡ , and the surface effect is relatively rough, showing a pockmarked surface. The greater the coating amount, the rougher the surface and the more serious the roller marks. If this method is used to produce UV topcoat on wood products, the surface of the produced product will not be plump. degree, and the roller marks are obvious. Due to the influence of the amount of coating, the glossy products above 96 degrees cannot be realized by ordinary roller coating, which cannot meet the needs of customers. In response to the abo...
