Furthermore, features defined as "first" and "second" may explicitly or implicitly include one or more of the features for distinguishing between descriptive features, non-sequential, non-trivial and non-trivial.
As shown in fig. 1 and 2, a process for preparing a decorative sheet having a surface with a concavo-convex texture, comprises the following steps:
step A, ink-jet printing patterns on the surface of a printing substrate 1 to obtain a pattern layer 2;
step B, uniformly coating transparent UV paint on the surface of the pattern layer 2 and curing to obtain a pattern protection layer 3;
step C, coating organic silicon resin on the position, which needs to be textured, on the surface of the pattern protection layer 3 and curing to obtain a texture layer 4;
and D, uniformly coating UV (ultraviolet) light-cured transparent resin on the surface of the whole printing substrate 1, standing for a period of time, wherein the surface tension of the cured organic silicon resin is lower than that of the UV light-cured transparent resin, and curing the UV light-cured transparent resin to form a convex UV light-cured transparent resin layer 5 and a concave texture layer 4, so as to prepare the decorative plate with the concave-convex texture on the surface.
The pattern layer 2 is obtained by ink-jet printing a pattern on the surface of the printing substrate 1, then transparent UV paint is uniformly coated on the surface of the pattern layer 2 and cured, the transparent UV paint does not shield the color pattern of the pattern layer 2, the color pattern printed by ink-jet printing in the step A can be protected, the ink-jet printing pattern is ensured not to be worn, then organic silicon resin is coated on the position, which needs to be textured, on the surface of the pattern protection layer 3, the organic silicon resin is attached to the surface of the pattern protection layer 3, a texture layer 4 is obtained after curing, at the moment, the texture layer 4 protrudes relative to the surface of the printing substrate 1, the UV light-cured transparent resin is uniformly coated on the whole surface of the printing substrate 1, and the printing substrate is kept still for a period of time, because the surface tension of the cured organic silicon resin is lower than the surface tension of the UV light-cured transparent resin, the UV light-cured transparent resin layer 5 and the texture layer 4 are convex, texture decoration on the surface can be carried out according to designed texture patterns, the concave texture is naturally vivid after the UV light-cured transparent resin layer is pulled away, the texture definition is high, the texture visual effect is good, and the problems that the decoration effect of the existing decoration plate is unnatural and the texture definition is low are solved.
In step C, the position on the surface of the pattern protection layer 3, which needs to have a texture, may be coated with a silicone resin by roll coating or digital jet printing; organic silicon resin is coated on the surface of the pattern protection layer in a roll coating mode, so that the texture definition is high, and the texture visual effect is good.
Further, as shown in fig. 3, before the step a of printing the inkjet-printed pattern on the surface of the substrate, the method further includes a picture processing step: importing the picture into Photoshop software for processing, dividing the picture into a CMYK layer and a texture layer, importing the processed data into printing pattern color management software, carrying out screening processing on the pattern to generate a data file, and finally transmitting the generated data file to an ink jet printer.
Specifically, print substrate 1 and be plates such as SPC board, calcium silicate board, plank, stone material, plastic-aluminum board, PVC panel, ceramic tile, ya keli, organic glass, steel sheet, aluminum plate, the preparation technology of decorative board that the surface has unsmooth texture can be applied to the decoration of above-mentioned multiple material, and application scope is wide, and decorative effect is good.
Preferably, the surface tension of the silicone resin after curing is 10 to 25mN/m lower than that of the UV light-cured transparent resin, preferably, the surface tension of the silicone resin after curing is in a range of 15 to 26mN/m, and the surface tension of the UV light-cured transparent resin is in a range of 25 to 40 mN/m.
