Problems solved by technology

However, the concave-convex porcelain tiles currently on the market are generally formed by pressing the concave-convex mold. The disadvantages are: the concave-convex surface is rigid and fixed, and the concave-convex surface cannot change randomly like na

Embodiment Construction

[0025] As shown in Figure 1 and Figure 2, the variable concave-convex surface texture decorative porcelain tile of the present invention includes a surface layer 1 and a base layer 2, and the surface layer 1 is set to have a cloth texture 3 and a concave-convex surface with ravines or pits 4 The ravines or pits 4 on the concave-convex surface vary naturally with the cloth texture 3, and the depth of the ravines or dents 4 is 0-1.5mm. The grooves or depressions are produced by the depression material 5 . The dry wear resistance of the depressed material 5 is lower than that of other patterned fabrics, and the firing shrinkage of the depressed material is higher than that of other patterned fabrics. The formula composition (parts by weight) of the depression material is: mud 8%, potassium feldspar 15%, sodium feldspar 25%, talc 6%, limestone 15%, wollastonite 15%, quartz sand 16%. The mud content in the powder formula composition of the surface layer 1 and the bottom base layer...

Abstract

The invention discloses a decorative porcelain tile with changeable grains on concave surfaces and convex surfaces and a manufacturing method thereof, which is characterized in that: when powders are prepared, facing materials for patterns of sunken materials are made up for the porcelain tile; a two-level polishing and grinding treatment which comprises a hard polishing-grinding and a soft polishing-grinding in sequence is carried out after a green body is dried; a sintering temperature between 1100 DEG C and 1300 DEG C is adopted for the facing materials, as a result, obviously downward sunken materials as well as concave and convex grains in gully or pit shapes that alter along with the changes of the patterns of the fabric can be sintered for the facing materials. By adopting the manufacturing method, the concave and the convex surfaces of the decorative porcelain tile can be randomly changed, the colors, patterns and grains are naturally altered along with the changes of the concave and convex grains, and the stone imitating effect is vivid.

Description

Technical field: [0001] The invention relates to a porcelain tile for architectural decoration and a preparation method thereof, more specifically a porcelain tile with a variable concave-convex surface texture decoration surface and a preparation method thereof. Background technique: [0002] At present, with the continuous progress of ceramic industry technology, formula and equipment, ceramic products are getting closer to the effect of natural stone, including color, texture, texture and surface effect. In recent years, natural stone, whose surface varies with uneven texture, is especially popular among designers and consumers, and is widely used in wall and floor decoration. However, this kind of stone is expensive, has low strength, poor wear resistance, poor antifouling performance and easy to change color, and the stone mineral reserves are limited. The artificial concave-convex surface porcelain tile has the advantages of low price, high strength, durability, no di...
