Description

Technical Field

[0001] The utility model relates to the technical field of digital printing decorative plates, in particular to a decorative plate for improving the effect of digital printing patterns. Background Art

[0002] At present, some indoor home decoration panels use digital inkjet printing and coating technology. The digital printing pattern truly restores the texture effect of precious stone and wood. It has brilliant colors, bright colors, lifelike images, and can be customized. It is a beautiful decorative panel, mostly used in interior decoration, office, civil furniture, door panels, public wall panels, partitions and other scenes.

[0003] Existing technology:

[0004] The existing digital printing of stone has many problems such as unrealistic texture, blurred and unclear patterns, which seriously affect the appearance of the finished board, resulting in low market customer acceptance and declining product sales. The existing process is to print ink directly on the printed white background. Due to the different surface tensions between the white background and the ink, the surface tension generated after the contact between the white background and the ink is more difficult to control under the semi-dry process energy requirements. The ink cannot be spread and carried better on the printed white background, resulting in many defects and deficiencies in the printed pattern.

[0005] Defects and shortcomings:

[0006] 1. The printed stone and wood patterns are distorted and the texture is not clear;

[0007] 2. The ink has poor color development on a white background, and the pattern is blurred, dark, and not bright;

[0008] 3. The white bottom layer and the ink layer are poorly spread, resulting in a decrease in the physical and chemical properties of the ink coating (interlayer adhesion). Utility Model Content

[0009] The utility model aims to provide a decorative plate with improved digital printing pattern effect in view of the technical defects and shortcomings in the prior art.

[0010] The technical solution adopted to achieve the purpose of this utility model is:

[0011] A decorative board for improving the effect of digital printing patterns comprises a base plate, a putty layer fixed on the base plate, a printed white base layer fixed on the putty layer, a 3D transparent developing layer fixed on the printed white base layer, and an ink layer fixed on the 3D transparent developing layer.

[0012] In the above technical solution, the bottom plate is a calcium silicate board with a thickness of 10 mm, the length of the calcium silicate board is not less than 2440 mm, and the width of the calcium silicate board is not less than 1220 mm.

[0013] In the above technical solution, the putty is UV putty.

[0014] In the above technical solution, grid grooves are provided on the putty layer.

[0015] In the above technical solution, the printed white bottom layer is fixed on the putty layer by UV curing.

[0016] In the above technical solution, the 3D transparent developing layer is fixed on the printed white bottom layer by UV curing.

[0017] In the above technical solution, the ink layer is fixed on the 3D transparent developing layer by UV curing.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The stone and wood patterns of the decorative board of the utility model are realistic and the texture is clear; the 3D transparent developing layer in the decorative board improves the color development of the ink, and the presented pattern is bright and vivid; the 3D transparent developing layer connects the printed white bottom layer and the ink layer, allowing the ink to spread perfectly on the transparent layer, and can form a good adhesion with the printed white bottom layer, playing a transitional role of connecting the upper and lower layers; the addition of the 3D transparent developing layer improves the appearance quality of the digitally printed decorative board and the qualified rate of the finished board. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 Shown is a schematic structural diagram of the decorative plate of the present utility model.

[0021] In the figure: 1-base plate, 2-putty layer, 3-printed white base layer, 4-3D transparent developing layer, 5-ink layer. DETAILED DESCRIPTION

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] Example 1

[0024] A decorative board for improving the effect of digital printing patterns, such as Figure 1 As shown, it includes a base plate 1, a putty layer 2 fixed on the base plate 1, a printed white bottom layer 3 fixed on the putty layer 2, a 3D transparent developing layer 4 fixed on the printed white bottom layer 3, and an ink layer 5 fixed on the 3D transparent developing layer 4.

[0025] In this embodiment, the bottom plate 1 is a calcium silicate board with a thickness of 10 mm, the length of the calcium silicate board is not less than 2440 mm, and the width of the calcium silicate board is not less than 1220 mm.

[0041] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the elements described as being "under" other elements or features will be positioned "on" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0042] Furthermore, relational terms such as “first” and “second” and the like are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any such actual relationship or order between these components.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
