However, in addition to waterproof and fireproof performance, enamel decorative panels for home use, art venues and other occasions also need to have good three-dimensional perception, texture effect and artistic expression. The texture patterns and textures on the current enamel decorative panels are basically processed by inkjet printing and transfer printing paper. Printing inkjet and transfer inkjet are limited by the process, and the texture patterns and textures are dull and not three-dimensional. At the same time, due to the equipment limitations of printing inkjet and transfer inkjet, large panels cannot be produced, and printing inkjet can only print arc panels and special-shaped panels.

[0033] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0036] The embodiment of the present invention provides a method for preparing a textured enamel substrate, which is made by using a formed steel plate as a substrate. Figure 1 As shown, specifically including:
[0037] First, glaze is sprayed on the surface of the formed steel plate substrate and sintered to form a base color glaze layer; the base color glaze layer serves as a base color layer, which, on the one hand, facilitates highlighting the color of the texture pattern subsequently formed on the texture layer, and on the other hand, serves as a reinforcement layer to facilitate the formation and coating of the subsequent coating.
[0038] Afterwards, texture glaze is sprayed on the base color glaze layer to form a texture glaze coating; wherein the texture glaze coating is in an unsolidified state and is in liquid form, which facilitates the formation of subsequent texture patterns.
[0039] Finally, a texture tool is used to form a desired texture pattern on the texture glaze coating, and the texture pattern is uneven, and then sintered at a first temperature for a first time to form a texture enamel substrate. Of course, the color of the texture pattern is determined according to the color of the texture glaze coating. The texture tool has a printed texture pattern template, and the template is uneven, so the uneven texture pattern can be formed by moving on the texture glaze layer.
[0040] The above-mentioned preparation method uses the base color glaze layer as the reinforcement layer, and can better form a texture glaze coating on the base color glaze layer, and form a texture pattern on the unsolidified texture glaze coating through a texture tool. The way to form the texture pattern is simple, the process is simple, and the texture pattern formed is uneven. Compared with the prior art of using inkjet printing and transfer printing paper to process the texture pattern, after the texture glaze coating is sintered, the texture pattern presents a three-dimensional sense, and has a good texture effect and artistic effect; and in the preparation process, different texture patterns can be formed on the texture glaze coating by replacing texture tools with different texture patterns, producing different textures to better meet the needs of users. Moreover, the above-mentioned texture tools can be manufactured by mold opening. In practical applications, the production volume is large and the cost will be reduced accordingly.
[0041] Of course, the texture glaze mentioned above is actually a surface glaze, but the texture glaze can be mixed into glazes of different colors according to needs.
[0042] Specifically, in this embodiment, if Figure 2 As shown, the steps of forming the base color glaze layer include:
[0043] First, spray the base glaze and the top glaze on the formed steel plate substrate in sequence, and sinter at the second temperature for the second time to form a bonding layer of the base glaze and the top glaze. Specifically, after coating, it is necessary to sinter at 830-860°C in a continuous enamel firing furnace for 3-5 minutes until the base glaze is fused with the formed steel plate substrate, and finally form a bonding layer of the base glaze + top glaze layer on the formed steel plate substrate. The bonding layer is used as the base color layer in the enamel plate, generally white, as the background color, to facilitate the highlighting of the color of the subsequent texture layer. Of course, the final bonding layer can also be another color, and you only need to adjust the color of the top glaze.
[0044] Then, a layer of texture glaze is sprayed on the bonding layer, and sintered at a third temperature for a third time. Specifically, the enamel is sintered in a continuous enamel firing furnace at a temperature of 780-830°C for 3-5 minutes until the texture glaze and the bonding layer are fused to finally form a base color glaze layer. The actual base color glaze layer includes three layers, a base glaze, a surface glaze and a texture glaze.
[0045] In this embodiment, after the formation of the above-mentioned base color glaze layer, texture glaze is sprayed on the base color glaze layer, which is equivalent to spraying another layer of texture glaze on the outermost texture glaze layer, and then using a texture tool to form an uneven texture pattern on the sprayed texture glaze coating. After sintering, it is equivalent to the two layers of texture glaze being partially fused, and finally the texture pattern will produce a color-changing effect under the external senses, and the aesthetics will be better. Moreover, a layer of texture glaze is applied between the texture pattern and the bonding layer, which is equivalent to thickening the thickness of the entire texture glaze layer, thereby avoiding the situation where the bonding layer is exposed after the texture pattern is formed on the outermost texture glaze layer and sintered.
[0046] Preferably, the texture glaze sprayed on the bonding layer and the texture glaze used to form the texture glaze coating on the base color glaze layer are the same or different in color, that is, the two layers of texture glaze formed on the bonding layer are the same or different in color. When the two layers of texture glaze have the same color, they increase the thickness, and the two layers of texture glaze are thicker. When the two layers of texture glaze have different colors, the user can adjust the color of the two layers of texture glaze and then adjust the color of the texture pattern formed to meet the user's processing needs.
[0047] In another embodiment, Figure 3 As shown, the steps of forming the base color glaze layer include:
[0048] First, the base glaze and the surface glaze are sprayed on the formed steel plate substrate in sequence, and sintered at a second temperature for a second time to form a bonding layer of the base glaze and the surface glaze. Specifically, after coating, it is necessary to sinter at a temperature of 830-860°C in a continuous enamel firing furnace for 3-5 minutes until the base glaze and the formed steel plate substrate are fused, and finally a bonding layer of the base glaze + surface glaze layer is formed on the formed steel plate substrate, and the bonding layer is the base color glaze layer. In this embodiment, the texture glaze is sprayed on the base color glaze layer to form a texture glaze coating, that is, the texture glaze is sprayed on the bonding layer to form a texture glaze coating, and then a texture tool is used to form a texture pattern on the texture glaze coating, and the process is simpler.
[0049] Specifically, in the bonding layer forming step, the bonding layer is sprayed by using an electrostatic dry powder two-coating-one-firing process, and in the texture glaze coating forming step, the texture glaze is sprayed by using a wet spraying process.
[0050] Specifically, the thickness of the bonding layer is 100-150 μm, the thickness of each layer of texture glaze is 50-150 μm, and the thickness of the base color glaze layer is 150-300 μm. Of course, the thickness of the texture layer is determined according to the required texture thickness.
[0051] Specifically, the texture tool used to form the texture pattern includes a roller, and the texture pattern is arranged on the roller. Specifically, in actual use, the roller can be selected from one or more of a toothed universal roller, an orange peel pattern roller, a sheepskin pattern roller, an artistic pattern roller, an artistic creative roller, etc., and can be selected according to actual conditions.
[0052] Specifically, before forming the base color glaze layer on the steel substrate, the steel substrate needs to be pretreated, including: cutting the steel plate substrate to be treated, bending the cut steel plate substrate into a predetermined shape and performing degreasing, rust removal and anti-rusting processes to finally form a formed steel plate substrate.
[0053] By coating a texture glaze layer on the base color glaze layer of the above-mentioned steel substrate, and then using a roller or other texture tools to form an uneven texture pattern on the texture glaze layer, after sintering, the three-dimensional shape is better, with good texture effect and artistic effect.
[0054] This embodiment also discloses an enamel decorative plate, such as Figure 4 As shown, it includes a textured enamel substrate 1 and a back plate 2, wherein the textured enamel substrate 1 is prepared by the above-mentioned preparation method, the back plate 2 is located on the back of the textured enamel substrate 1, and the gap between the back plate 2 and the textured enamel substrate 1 is filled by a sealant, specifically, the sealant includes a sealant 1. Specifically, the back plate 2 adopts one of a silicate cover plate and an aluminum honeycomb core plate.
[0055] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
