Description

Technical Field

[0001] The invention belongs to the technical field of building materials, relates to a wallboard, and in particular to a concave-convex treatment process for the surface of a wallboard. Background Art

[0002] Wallboards can be used for wall decoration, heat insulation, sound insulation, moisture and fire resistance, and are usually made of renewable and recyclable materials such as wood and cement. The surface treatment of wallboards is generally based on film, hot-pressed impregnated triamine paper, pure color roller pressing, and spray painting. After surface treatment, the surface of the wallboard is mostly pure flat, and the three-dimensional effect of the surface decorative pattern cannot be shown. Summary of the invention

[0003] In order to overcome the defect of the prior art that the three-dimensional effect of the flat decorative pattern cannot be highlighted, the present invention discloses a concave-convex treatment process for the surface of a wall panel.

[0006] A. Roller-coat UV paint on the pre-treated substrate surface, dry → UV putty paint, dry, sand → UV adhesion paint / UV glue, dry;

[0007] B. Roller-coat UV paint, roll the printed pattern onto the surface of the substrate, and cure it with UV lamp;

[0008] C. Print the pre-designed pattern onto the surface of the substrate using a 3D printer and solidify it with an LED light;

[0009] D. Apply UV functional topcoat, including matte or glossy, with a coating amount of 10-30g / m 2 , UV drying;

[0010] E. Grading and packaging.

[0011] In a preferred embodiment of the present invention, the pre-treated substrate in step A is pre-treated on the wallboard substrate, including: coating the back of the substrate with UV paint by roller, with a coating amount of 10-20 g / m 2 , UV drying; roller coating of UV adhesion primer or penetrant on the surface of the substrate, UV lamp curing; the specific coating amount is determined according to the material and density of the substrate, the purpose is to control the thickness of the substrate surface and fill the pits on the substrate surface.

[0012] In a preferred disclosed example of the present invention, the substrate in step A is any one of crystal rock wallboard, soft stone board, inorganic pre-coated board, stone-plastic composite board, with a thickness of 2 to 30 mm, preferably an inorganic pre-coated board with a thickness of 12 mm.

[0013] In a preferred disclosed embodiment of the present invention, in step A:

[0014] The roller coating UV paint has a coating amount of 30 to 70 g / m 2 , preferably 50g / m 2 ;

[0015] The UV putty paint has a roller coating amount of 20 to 30 g / m 2 , preferably 25g / m 2 ;

[0016] The UV adhesion paint has a roller coating amount of 10 to 20 g / m 2 , preferably 15g / m 2 ;

[0017] The UV glue is coated with a roller at a rate of 10 to 20 g / m 2 , preferably 15g / m 2 .

[0018] In a preferred disclosed example of the present invention, the printing pattern roller printing described in step B is to engrave the printing pattern on the surface of the silicone roller, and the engraved printing roller surface has different height differences. The coating amount of the UV paint is controlled by a scraper during roller coating, and a concave-convex effect is presented on the surface of the substrate after UV light curing.

[0019] In the preferred disclosed example of the present invention, the 3D printer described in step C is an industrial inkjet 3D printer, which uses varnish to print the pattern on the substrate and solidifies it with an LED lamp. Since the ink of the printed pattern is varnish, the varnish is directly solidified on the surface of the substrate after illumination, presenting different concave and convex feelings.

[0020] The present invention superimposes 3D printing on the effect of roller printing, so that the surface of the wall panel presents a significant three-dimensional effect.

[0021] The wallboard with a concave-convex 3D effect on the surface prepared according to the above method includes a substrate and a paint layer on the surface of the substrate, wherein the paint layer includes a penetration layer, a putty layer, a sanding layer, an adhesion layer, a printing layer, a printing layer and a topcoat layer from bottom to top.

[0022] Beneficial Effects

[0023] The present invention combines roller printing with 3D printing to process the surface of the wall panel, so that it presents different texture effects, and the three-dimensional effect of the surface can be achieved without the traditional steel plate molding and wire drawing process; 3D printing is used to change the original plate making, transfer, and silk screen traditional processes, and different images are directly presented on the substrate, which changes the development direction of the original product manufacturing, and not only increases operability, improves production efficiency, but also increases product added value.
