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 silk- and satin-texture ceramic glaze which comprises the following components in parts by weight: 10-35 parts of calcined shell powder, 15-36 parts of potassium feldspar, 15-30 parts of albite, 0-10 parts of dolomite, 5-15 parts of boric acid, 12-25 parts of quartz and 5-15 parts of clay. According to the ceramic glaze disclosed by the invention, CaO is introduced by taking the calcined shell powder containing a large amount of nepheline crystal forms as a raw material, so that the ceramic glaze has the decorative effects of silk-like luster and texture and the advantage of excellent comprehensive performance of a glaze surface after sintering molding on the premise that a frit glaze raw material with a narrow sintering range is not required to be added; meanwhile, the production cost is low, the firing range is wide, and the glaze is particularly suitable for surface decoration of ceramic rock plates. The invention further discloses a ceramic rock plate withthe silk and satin texture on the surface, and the problems that an existing ceramic rock plate product is poor in surface decoration effect, and an existing ceramic brick with the silk glaze effectis narrow in firing range and high in production cost are solved.

Description

technical field [0001] The invention relates to the field of architectural ceramic materials, in particular to a satin-like ceramic glaze, a preparation method and a ceramic rock plate using the same. Background technique [0002] In the current home space decoration, the common materials are ceramics, metal, wood, natural stone, artificial stone, artificial board, fabric, plastic, leather, paint and so on. However, many decoration materials are neither environmentally friendly nor durable. For example, artificial boards will emit harmful substances for a long time, and have defects such as short service life, easy cracking, peeling, fear of blisters, etc., and are more likely to be attacked by termites. Another example is artificial stone, which also has discoloration and mildew over time. , smelly and other defects, while natural stone has excellent performance, but its specifications are limited and the price is high. [0003] Therefore, among the above-mentioned decora...
