Description

Preparation method of color super-matte decorative plate with three-dimensional grains
The application is a divisional application of a Chinese patent application, which is entitled "a method for preparing a color super-matte decorative plate with three-dimensional grains" and has an application date of 2021, 9 and 27 months and an application number of 202111137666.8.
Technical Field
The invention relates to the technical field of decorative plates, in particular to a preparation method of a color super matte decorative plate with three-dimensional grains.
Background
With the development of society and the improvement of living standard of people, the requirements of people on the home decoration industry are higher and higher, and the common plane decoration plate is lack of beauty and attraction due to the fact that the surface of the common plane decoration plate has no three-dimensional grains and patterns, and is difficult to meet the requirements of consumers. Therefore, decorative boards with three-dimensional patterns are receiving more and more attention. In the prior art, the three-dimensional grain of the decorative plate is usually formed by pressing or carving, and mainly comprises the following modes:
(1) And (4) carrying out hot pressing on the melamine veneer to enable the surface of the melamine veneer to have grains. However, the lines which can be pressed by the method are not three-dimensional (the vertical depth is less than 1 mm), the deformation of the pressed lines is large, and the melamine plate is easy to tear, and is not bright in color and high in glossiness;
(2) And (4) spraying UV coating after engraving the density board. The method is specifically operated in that firstly, seal primer (about 15-20 mu m) is sprayed on the special-shaped surface of the carved density board, the special-shaped surface is manually polished and sanded, then, 3-5 colored paint layers (each layer is about 10-15 mu m) are sprayed, each colored paint layer needs UV curing, and finally, a transparent finish paint layer (10-20 mu m) is sprayed on the colored paint layer and then UV curing is carried out. However, through the series of spraying and curing, the operation is complex, manpower and material resources are consumed, the carved fine grains are easily filled by the UV coating, and the obtained decorative plate is not bright enough in color and low in glossiness;
(3) And (4) rolling the density board with UV coating and then pressing. The method is specifically operated by firstly rolling a sealing primer (about 15-20 mu m) on a density board, then carrying out UV curing and sanding, then coating 3-5 layers of color primers (each layer is about 10-15 mu m), wherein each layer of color primer needs UV curing, then coating a sanding primer (about 20 mu m), then carrying out UV curing and sanding, finally coating a surface paint layer (about 20-25 mu m), then carrying out UV curing, and finally carrying out hot pressing. Therefore, the total thickness of the coating reaches 105-145 mu m when hot pressing is carried out, the coating is easy to crack when hot pressing is carried out, patterns with vertical depth larger than or equal to 1mm are difficult to press, and the color is not bright enough.
(4) And (3) coating a PETG sheet with three-dimensional patterns on the artificial board through hot melt adhesive. The stereo-colored PETG sheet film on the market at present can be produced only by Korean LG, the price is high, and the cost of a single PETG film material reaches more than 50 yuan per square meter. The whole plate after film pasting is not heat-resistant, and layering and bubbling between plates and films are easy to occur when the plate surface temperature is higher than 80 ℃.
Therefore, it is necessary to provide a method for manufacturing a color super-matte decorative sheet with simple manufacturing process, low cost, fine pressed texture and bright color.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
