Problems solved by technology

[0008] To sum up, at present, ceramic products with silk glaze effect are mainly produced by adding fritted glaze. This production method makes the firing range narrow and the production cost is high; or more expensive raw materials are added.
In addition, the glaze texture of the existing ceramic slab products is relatively single, which cannot satisfy

Abstract

The invention discloses a satin-like ceramic glaze, which comprises the following components in parts by weight of raw materials: 10-35 parts of calcined shell powder, 15-36 parts of potassium feldspar, 15-30 parts of albite, dolomite 0-10 parts, 5-15 parts of boric acid, 12-25 parts of quartz, 5-15 parts of clay. The ceramic glaze of the present invention uses calcined shell powder containing a large amount of nepheline crystal form as a raw material to introduce CaO, and without adding frit glaze raw materials with a narrow firing range, the ceramic glaze has both satin-like luster and texture The decorative effect and the comprehensive performance of the glaze after sintering are excellent. At the same time, the production cost is low and the firing range is wide. It is especially suitable for the surface decoration glaze of ceramic rock slabs. The invention also discloses a ceramic slab with satin texture on the surface, which solves the problems of poor surface decoration effect of existing ceramic slab products, narrow firing range and high production cost of existing silk glaze effect ceramic tiles. question.

Description

technical field [0001] The invention relates to the field of building ceramic materials, in particular to a ceramic glaze with satin texture, a preparation method and a ceramic slate using the same. Background technique [0002] In the current home space decoration, common materials are ceramics, metal, wood, natural stone, artificial stone, artificial board, fabric, plastic, leather, paint, etc. However, many finishing materials are neither environmentally friendly nor durable. For example, artificial boards will emit harmful substances for a long time, and have short service life, easy cracking, peeling, fear of blisters and other defects, and are more likely to be attacked by termites. Another example is artificial stone, which will also change color and mildew over time , odor and other defects, and although natural stone has excellent performance, its specifications are limited and the price is high. [0003] Therefore, among the above decoration materials, ceramic sl...
