Description
Technical Field
[0001] The invention relates to a production method of thin regenerated stone, belonging to the technical field of products composed of flat thin layers. Background Art
[0002] In the prior art, the production and processing of regenerated stone generally involves first forming the stone and then printing the pattern texture. In this way, the regenerated stone is easily peeled off and faded during long-term use, causing the color to fade, thus seriously affecting the appearance. Summary of the invention
[0003] In order to solve the above technical problems, the present invention provides a method for producing thin regenerated stone. The method for producing thin regenerated stone can effectively solidify and sinter the pattern texture in the formed stone by adding color-adjustable oxides, first printing and then sintering, thereby effectively preventing the pattern texture from falling off and disappearing during long-term use.
[0004] The present invention is achieved through the following technical solutions.
[0005] The present invention provides a method for producing a thin regenerated stone, comprising the following steps: S1. Mixing preparation: mixing silicate, oxide, alkali metal oxide, alkaline earth metal oxide and rare earth element oxide according to the glaze ratio to obtain glaze slurry; S2. Slurry spraying: spray the glaze slurry onto the surface of the fiber cloth with a spray gun; S3, drying: drying the fiber cloth naturally or in a drying oven to form a thin layer of stone; S4, Printing and spraying: Use digital inkjet printing technology to spray a preset pattern on a thin layer of stone and sinter the thin layer of stone.
[0006] The silicate is silicon dioxide.
[0007] The oxides include iron oxide, cobalt oxide, copper oxide, manganese oxide, and chromium oxide, and are used to adjust the color and provide specific spectral effects.
[0008] The alkali metal oxides include sodium oxide and potassium oxide, which are used to reduce the melting point and improve fluidity.
[0009] The alkaline earth metal oxides include calcium oxide and magnesium oxide, which are used to improve hardness and durability.
[0010] The rare earth element oxide is a compound composed of a rare earth element and oxygen atoms, and is used to adjust color, provide specific spectral effects, and improve the performance of glazes.
[0011] The fiber cloth is glass fiber cloth or basalt fiber cloth.
[0012] The step S4 comprises the following steps: S41. Design patterns: Use computer-aided design software to construct preset patterns; S42, prepare for printing: apply a coating for ink attachment on the surface of a thin layer of stone; S43, inkjet printing: Use a digital inkjet printer to directly spray the preset pattern onto the surface of the thin layer of stone to achieve printing; S44, curing: curing the inkjet printed thin layer of stone at high temperature; S45, high temperature treatment: baking thin layers of stone.
[0013] The high temperature curing temperature in step S44 is 800-1000° C., and step S44 is used to cure the inkjet ink and preheat the thin layer of stone at the same time.
[0014] The baking temperature in step S45 is 1100-1200° C., which is used to sinter the thin layer of stone.
[0015] The beneficial effects of the present invention are: by adding color-adjustable oxides, first printing and then sintering, the pattern texture can be effectively solidified and sintered in the formed stone, thereby effectively preventing the pattern texture from falling off and disappearing during long-term use; it is easy to match colors, beautiful and durable. BRIEF DESCRIPTION OF THE DRAWINGS
[0016] Figure 1 It is a schematic diagram of a process flow of at least one consistent implementation mode of the present invention. DETAILED DESCRIPTION
[0017] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.
[0018] A first embodiment of the present invention relates to Figure 1 A production method of a thin regenerated stone material is shown, comprising the following steps: S1. Mixing preparation: mixing silicate, oxide, alkali metal oxide, alkaline earth metal oxide and rare earth element oxide according to the glaze ratio to obtain glaze slurry; S2. Slurry spraying: spray the glaze slurry onto the surface of the fiber cloth with a spray gun; S3, drying: drying the fiber cloth naturally or in a drying oven to form a thin layer of stone; S4, Printing and spraying: Use digital inkjet printing technology to spray a preset pattern on a thin layer of stone and sinter the thin layer of stone.
[0019] Thus, the stone mixture is mixed in accordance with the proportion of the glaze, and the dual functions of the stone body material and color are combined into one. In step S2, the pre-pattern drawing can be realized by spraying a variety of different colors, and such pattern drawing uses the color of the material itself as a carrier, and a certain degree of pattern drawing is achieved from the material background color, which lays the foundation for subsequent printing pattern drawing, and can significantly and more effectively avoid problems such as pattern texture falling off.
[0020] The second embodiment of the present invention is substantially the same as the first embodiment, except that, in a further preferred embodiment, the silicate is silicon dioxide.
[0021] Further, oxides include iron oxide, cobalt oxide, copper oxide, manganese oxide, and chromium oxide, which are used to adjust the color and provide specific spectral effects.
[0022] Furthermore, alkali metal oxides include sodium oxide and potassium oxide, which are used to lower the melting point and improve fluidity.
[0023] Furthermore, alkaline earth metal oxides include calcium oxide and magnesium oxide, which are used to improve hardness and durability.
[0024] Furthermore, rare earth element oxides are compounds composed of rare earth elements and oxygen atoms, which are used to adjust colors, provide specific spectral effects and improve the performance of glazes.
[0025] Furthermore, the fiber cloth is glass fiber cloth or basalt fiber cloth.
[0026] The third embodiment of the present invention is substantially the same as the first embodiment, mainly in that the preferred scheme of printing, curing and sintering is adopted, and step S4 comprises the following steps: S41. Design patterns: Use computer-aided design software to construct preset patterns; S42, prepare for printing: apply a coating for ink attachment on the surface of a thin layer of stone; S43, inkjet printing: Use a digital inkjet printer to directly spray the preset pattern onto the surface of the thin layer of stone to achieve printing; S44, curing: curing the inkjet printed thin layer of stone at high temperature; S45, high temperature treatment: baking thin layers of stone.
[0027] Preferably, the temperature of high temperature curing in step S44 is 800-1000° C., and step S44 is used to cure the inkjet ink and preheat the thin layer of stone at the same time.
[0028] Preferably, the baking temperature in step S45 is 1100-1200° C., which is used to sinter the thin layer of stone.
[0029] Therefore, in step S43, there are still gaps in the thin layer of stone. While the ink is attached to the surface coating, part of it can penetrate into the gaps in the thin layer of stone. In step S44, the thin layer of stone has not yet been sintered at 800~1000℃, and the ink is solidified at this temperature first. On the one hand, it can effectively improve the durability of the ink, and on the other hand, it can avoid discoloration of the ink due to excessively high temperatures. Finally, in step S45, the thin layer of stone is ceramicized and sintered, which greatly improves the overall hardness and durability.
