Embodiment 1

[0035] Example 1: UV finishing process of decorative board sticker pattern

[0036] First use a belt sander (effective sanding width greater than 1250mm) with 150#+240# two sanding units to fully sand the unattached side of the single-sided melamine decorative board, and it must be smooth and smooth . Use a gluing machine or a roller to evenly coat the sanded side with white latex, with an amount of 50g per square meter, and immediately attach the cut decorative paper to the board without wrinkles and air bubbles, and then place the pasted board Press in the adjusted hot press for 5 minutes, the temperature of the hot press is 40 degrees Celsius, and the pressure is 100 bar. After an interval of 15 hours, spray the transparent resin varnish on the paper surface, let the varnish penetrate into the paper and cure naturally. After it is fully cured, polish it thoroughly with a white cleaning cloth, and do not break the paper surface. Adjust the UV assembly line, clean the poli...

Embodiment 2

[0037] Example 2: UV finishing process of decorative board PU solid color.

[0038] a. Stick coating process to coat PU color paint;

[0039] First use a belt sander (effective sanding width greater than 1250mm) with 150#+240# two sanding units to fully sand one side of the double-sided melamine decorative board, and it must be smooth and smooth. Use a PU stick coater to divide the PU color paint into three times on the sanded side, and apply 70 grams per square meter each time evenly. After the color paint is fully surface-dried (25°C, 4 hours), apply the PU varnish again. 100 grams per square meter. go to C.

[0040] b. Spraying process to coat PU color paint;

[0041] First use a belt sander (effective sanding width greater than 1250mm) with 150#+240# two sanding units to fully sand one side of the double-sided melamine decorative board, and it must be smooth and smooth. Use a spray gun to evenly coat the PU color paint at 250 grams per square meter on the side that has...

Embodiment 3

[0043] Example 3: UV finishing process of decorative board PU metal color.

[0044] First use a belt sander (effective sanding width greater than 1250mm) with 150#+240# two sanding units to fully sand one side of the double-sided melamine decorative board, and it must be smooth and smooth. Use a spray gun to evenly coat the PU metal color paint with 450 grams per square meter on the side that has been sanded. After the metal color paint is fully surface-dried (25 ° C, 4 hours), spray another PU varnish of 100 grams per square meter. Put it aside for 12 hours until it is fully cured, and then polish it fully with 320# sandpaper, adjust the UV assembly line, clean the polished board and send it to the roller coater, and apply 10g of UV primer per square meter with the technology of showering and rolling before entering. Flow coater, spray 80g of UV primer, adjust the oil temperature and oil pump, transmission speed according to the model of the paint manufacturer, and enter the ...

Abstract

The invention relates to a processing method of decoration boards. The decoration boards are processed by the substrate material surface and substrate material coloring and UV rays fixes the base lacquer and the surface lacquer by the forward drench-roll technology and the drench-spread technology. The substrate materials are particle board adhered with melamine fumiture surface paper on single or double faces or medium density fiberboard. The steps comprise 1) substrate material surface is processed; 2) substrate material surface is colored; 3) the base lacquer is fixed by UV rays; 4) the surface lacquer is fixed by UV rays. Prior to step 4), a step of polishing can also be comprised, i.e. large-scale polishing machine polishes the whole base lacquer after the fixing machine of UV rays fix completely. After the step 4), a step of cleaning package can also be added, that is, micro flaws can be removed that decoration boards with small bubbles or unapparent impurities are polished by dropping sand and package is checked. The decoration boards produced by the method has the advantages of wear resistance, environmental protection, rich and bright colors.

Description

technical field [0001] The invention belongs to the field of furniture materials and decorative boards for decoration, in particular to a method for processing a decorative board coated with light-cured paint on the surface. Background technique [0002] At present, most of the decorative panels used for furniture materials and decoration are: PU baking varnish, melamine veneer, PVC laminated film and other decorative panels based on particleboard or MDF. The PU baking varnish board has the problem of environmental pollution, and the surface hardness is low, and it is not scratch-resistant; the decorative panel with melamine veneer has poor surface effect and single color; the surface of the decorative panel with PVC laminated film lacks brightness and three-dimensional performance effect. Therefore, the applicant has developed a UV finishing process for decorative panels that are wear-resistant, environmentally friendly, colorful and rich, and high-gloss. Contents of the ...
