Preparation method of simulation wood grain three-dimensional decorative household board

Abstract

The invention relates to a preparation method of a simulation wood grain three-dimensional decorative household board. The preparation method comprises the following steps: preparing a simulation wood grain digital color pattern standard image and a simulation wood grain digital black and white pattern standard image; standardizing the decorative surface of the base material; coating a base coating on the decorative surface; coating a color coating on the prime coating by using the simulation wood grain digital color pattern standard image; coating a floating coating on the pattern coating; the floating coating is coated with a reaction type UV transparent 3D primer coating; and a reaction type 3D ink coating is jet-printed on the position required by the liquid and uncured reaction type UV transparent 3D primer coating by using the simulated wood grain digital black and white pattern standard image, so that the reaction type UV transparent 3D primer and the reaction type 3D ink react to finally form a concave-convex effect layer, and the surface coating is coated on the obtained coating. The artificial wood grain three-dimensional decorative plate has a better artificial wood grain three-dimensional decorative effect, and the production process is simple, easy to implement, high in production efficiency and low in production cost.

Description

technical field [0001] The invention relates to the field of coating and processing of interior decorative boards, in particular to a method for preparing a simulated wood grain three-dimensional decorative home board. Background technique [0002] The Chinese invention patent with the patent application number 202011353859.2 discloses a digital wood grain 3D digital printing decorative board and its production process, which solves the problem of poor coloring after the addition of light absorbers, so that the color difference value △E≤ 1.0, to improve the use experience of the board. But the technical scheme of this invention only sets an inkjet printing or spraying process, and the design and color pattern of its decorative surface and 3D surface effect are sprayed and formed at one time, and the decorative coating of the 3D three-dimensional part on the decorative surface mainly depends on the ink coating. It is piled up, but because the ink is expensive (note: the pric...

AI Technical Summary

Problems solved by technology

Although, compared with the patent application number 202011353859.2 of this technical solution, the three-dimensional decorative effect of the decorative surface is more obvious, but the 3D effect decorative coating is mainly formed by expensive ink spraying and stacking. If the concave-convex effect of ink printing If the coating amount of the layer is too small, the concave-convex effect will not be obvious, and if the coating amount is large, the cost will be too high; therefore, the cost performance of the finished product is not ideal, and there is a problem that the production cost of the product is relatively high, and it is difficult to popularize it.

[0004] In addition to the above-mentioned problems, various technical solutions in the current prior art are only developed for the coating of a certain material or a certain substrate with a 3D stereoscopic effect, and none of them have comprehensively considered the coating with a 3D stereoscopic effect The versatility or universality of the technical solution in the coating process of simulating the three-dimensional decorative effect of wood grain, and when it is applied to different substrates, the material color difference, surface hardness, and permeability between different substrates Differences in surface properties such as porosity, moisture content, and apparent density will affect the final coating effect of the product. It cannot guarantee that the same coating process can obtain the same decorative effect when applied to different substrates, and cannot satisfy users and customers. Consumers' differentiated or personalized market demand for "same surface decoration effect, different substrates"
