Rock plate with engraved textures and preparation method thereof

Abstract

The invention discloses a rock plate with engraved textures and a preparation method thereof, the rock plate comprises a green body, auxiliary additives and ink, the green body comprises broad-peak water frosted sand, Jiaohui powder, calcined talc, 102 stone powder, an ultra-white pigment, FC ball clay, Jingle water frosted sand and Tianhe soil; the auxiliary additives comprise carboxymethyl cellulose sodium, a polymer reinforcing agent, a deflocculating agent No.2, sodium tripolyphosphate, a diluent and water glass, the ink comprises powder, a solvent, a dispersing agent, an anti-settling agent and a surfactant, and seven steps of material preparation, compression molding, texture carving, ink jetting, glazing, glaze firing and finished product polishing and grinding are performed, the rock plate can be realized without converting a press mold, the process flow is simplified, the concave-convex mold effect is generated visually and actually, and the colorful pattern has a more three-dimensional effect, and thus the rock plate with the engraved textures is vivid in texture and stronger in three-dimensional sense.

Description

technical field [0001] The invention relates to the technical field of ceramic tile production, in particular to a rock slab with carved texture and a preparation method thereof. Background technique [0002] Due to its heavy weight and poor machinability, architectural porcelain tiles have been used on the ground or walls since the advent of architectural porcelain tiles, and the usable areas are small. Compared with traditional porcelain tiles, slate tiles have the characteristics of a full body, and the texture is comparable to natural marble, with better compactness (water absorption <0.1%), larger size, lighter weight, thinner thickness, and better mechanical properties. protrude. Therefore, the application field of slate tiles is wider than that of porcelain tiles. The former is more suitable for large spaces such as countertops and background walls. Customized styling after processing. At present, in the technical scheme of ceramic products with concave-convex e...

Problems solved by technology

At present, in the technical scheme of ceramic products with concave-convex effect texture, the traditional method in the industry is to use the texture mold carved in kind to copy. For ceramic products, the surface of the pressing mold of the press is made into a concave texture with a predetermined depth, and then Use it to press ceramic raw materials to make ceramic products with concave-convex effect on the surface; the technical method is to design the pattern first, then carve it into a master mold in a mold factory, and then pass the texture on the master mold through The pressurized method is engraved on the heated cooked glue, and after cooling, it will be bonded with the corresponding mold, and then sent back to the manufacturer for use. This method is cumbersome, and each mold can only correspond to one texture. When a variety of textures are required, multiple sets of texture molds need to be prepared. Every time the texture is changed, the production line needs to be suspended for mold replacement. This is a huge waste of manpower and material resources, and the texture of the texture mold and the surface pattern sometimes appear after long-term use. Deviation, so that the product grade dropped sharply
