Embodiment 1
[0019] Ordinary sandstone is used as raw material to obtain smooth and flat stone slabs after cutting and grinding. Use a 3.5 million-pixel digital camera to take pictures of the pre-selected patterns, and then input them into the computer to build a sketchpad picture database. Select pictures from the database, design and finalize the painting; use a printer to make a 1:1 rendering of the stone painting board surface and fix it on the surface of the stone board. Cut and polish with a stone engraving machine to make a drawing board. Fill the gaps and holes in the drawing board with a paste made of sandstone powder and marble glue. Bake at 60°C for 2 hours. Use a stone grinder to remove excess filler from the screen. Bake at 60°C for 1 hour, then cool to room temperature. Color the drawing board with water-soluble pigments, and make the pigment penetrate into the drawing board by 1-2 mm to form a complete overall pattern effect. Carry out polishing, anti-fouling and waterp...
Embodiment 2
[0021] Repeat Example 1 with the following difference: the drawing board filled with the paste is baked at 80° C. for 1 hour. Use a stone grinder to remove excess filler from the screen. Bake at 80°C for 0.5 hour, then cool to room temperature. Color the drawing board with water-soluble pigments, and let the pigment penetrate into the drawing board by 1 mm to form a complete overall pattern effect. Carry out polishing, anti-fouling and waterproof treatment on the drawing board. Bake at 65°C for 0.5 hour to obtain a sandstone painting with a matte effect on the surface of the drawing board.
Embodiment 3
[0023] Bake at 70°C for 1.5 hours. Use a stone grinder to remove excess filler from the screen. Bake at 70°C for 40 minutes, then cool to room temperature. Color the drawing board with water-soluble pigments, and make the pigment penetrate into the drawing board 1.5 to achieve the overall pattern effect. Carry out polishing, anti-fouling and waterproof treatment on the drawing board. Bake at 60° C. for 0.5 hour, and then polish to form a mirror effect on the surface of the drawing board, and obtain the desired sandstone painting.
