[0002] At present, the indoor home furnishing industry uses 3D digital inkjet printing to truly restore the effects of precious stones and woods in patterns, which can not only reduce the consumption of natural stones and woods, but also can be customized according to needs, so as to meet the needs of multiple application scenarios, such as indoor decoration, office, civil furniture, door panels, wall panels and partitions in public places, etc.
[0003] The existing 3D digital inkjet printing method mainly realizes the raised texture effect by stacking printing inks layer by layer. However, the above-mentioned layer-by-layer stacking method has the following deficiencies: First, the existing printing technology mainly relies on inkjet stacking to achieve the raised texture effect, which does not conform to the downward concave texture characteristics of wood itself; moreover, the stone and wood texture patterns printed by the existing printing technology are distorted, blurred and unclear, with a shallow depth, and the 3D texture touch effect is poor; finally, a large amount of ink needs to be stacked during the printing process, so the printing cost is relatively high. Summary of the Invention

[0009] Further, after obtaining the textured surface, it further includes:
[0010] Drying and shaping the textured surface.
[0011] Further, the foaming agent is used to form an upward texture.
[0012] Further, spraying the upper coating material on the upper surface of the 3D texture bottom is used to generate a downward concave texture on the 3D texture bottom.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners. The existing 3D digital inkjet printing method mainly realizes the texture effect of pictures by stacking and coating printing ink layer by layer. However, the above-mentioned layer-by-layer stacking method has the following deficiencies: First, the existing printing technology mainly relies on inkjet stacking to achieve the raised texture effect, which does not conform to the downward concave texture characteristics of the wood itself; Second, the texture patterns of stone and wood printed by the existing printing technology are distorted, blurred and unclear, and the depth is shallow, and the 3D texture touch effect is poor; Finally, a large amount of ink needs to be stacked during the printing process, so the printing cost is relatively high.
[0029] Embodiment 1
[0030] As Figures 1 to 2 shown, the present invention provides a method for improving the texture effect of 3D digital inkjet printed decorative boards, including:
[0031] S10: Inkjet print a plane pattern on a prefabricated printed white background, and then spray a bottom coating material on the plane pattern to obtain a 3D texture bottom; It should be added here that before performing step S10, putty also needs to be coated on the board to obtain the printed white background. During the process of coating putty, existing processes such as back coating and penetration are also involved, which will not be elaborated here.
[0032] S20: Spray an upper coating material on the upper surface of the 3D texture bottom. The upper coating material includes a 3D texture liquid with a foaming agent to obtain a texture surface, which is used to generate a downward concave texture on the 3D texture bottom. And after obtaining the texture surface, the texture surface also needs to be dried and shaped. The equipment used for drying and shaping includes but is not limited to LED lights.
[0033] Due to the difference between the bottom coating material and the upper coating material, a huge downward thrust will be formed when the upper coating material is applied, and a downward concave texture will be formed during the process of pushing aside the bottom texture coating material;
[0034] And the above foaming agent is used to form an upward texture. The above foaming agent is sprayed on the underlying coating material together with the 3D texture liquid. During the spraying process, with the mutual accumulation and rupture of bubbles, and the process of drying and shaping, an upward texture is formed, and this upward texture and the concave texture form a texture surface. Foaming agents are generally surfactants, and their molecular structure has a so-called "amphiphilic structure" molecule with both hydrophilic and lipophilic properties. The foaming agent is added to the texture liquid to form small bubbles arranged in an oriented manner, and it ensures that the bubbles rise to form a foam layer.
[0035] It should be added here that in addition to the foaming agent, the above 3D texture liquid also includes resin, monomer TP, photoinitiator, leveling agent, and monomer HEMA. The proportions of each substance are shown in Table 1:

[0039] A method for improving the texture effect of a 3D digital inkjet printed decorative board provided by an embodiment of the present invention uses an underlying coating material and an upper coating material, and utilizes the difference in tension between the two to achieve a concave texture. At the same time, a self-made foaming agent is added to the upper coating material to form an upward texture during the process of foaming and bursting, thereby optimizing the texture effect and achieving the same technical effect as a large amount of ink accumulation, thus reducing the printing cost.

[0044] The foaming agent is used to form an upward texture, and its formation method has been described in the foregoing embodiments and will not be elaborated here. In addition to the foaming agent, the above 3D texture liquid also includes resin, monomer TP, photoinitiator, leveling agent, and monomer HEMA.
