Description
Technical Field
The invention relates to the field of ceramic materials, in particular to an energy-saving ceramic decorative material and a preparation method thereof.
Background
Ceramic materials are usually inorganic nonmetallic materials which are prepared by using clay as a main raw material and performing raw material treatment, molding and roasting. The building decoration ceramic is ceramic material for building wall, floor and sanitary equipment. At present, the building wall decoration materials mainly comprise ceramic tiles, ceramic plates, stones, metals, glass curtain walls, exterior wall coatings and the like. The development of exterior wall finishing materials has been advanced from the mere pursuit of decorative effects to additional functions thereof. So-called additional functions include: thermal insulation, sound insulation, environmental protection, energy consumption reduction, etc. Now, the additional function of the exterior wall finishing material is receiving a great deal of attention. In addition, as the global requirements for energy conservation and emission reduction are increasingly increased, and energy conservation and emission reduction of buildings are an important field, energy conservation building materials and energy conservation buildings become important directions for future development in the field.
The main products of ceramic tile are ceramic face brick, sanitary ceramic, large ceramic veneer, decorative glazed products, etc. The ceramic tile comprises an outer wall tile, an inner wall tile (glazed tile) and a floor tile. Glazed tile is also called as inner wall tile, and is a thin-sheet fine ceramic building product for decorating inner wall. It cannot be used outdoors, otherwise it would cause cracking damage through sun, rain, wind, freezing. The glazed tile has various colors including white, color, pattern, no light, stone, etc. and may be spliced into various patterns, calligraphy and painting with high decoration effect.
Along with the continuous improvement of the economic level, people pay more and more attention to whether living environment is healthy and comfortable, and the house is not purely provided with the function of shielding wind and rain. The heat preservation is to set a heat preservation layer on the building wall, which can keep the indoor temperature balanced and stable, make the house warm in winter and cool in summer, and promote the living comfort. The current building energy consumption is large, the building energy-saving work is not slow, and the heat preservation is not the only means for building energy saving, but also indispensable. The building heat preservation generally comprises an external heat preservation technology and an internal heat preservation technology, wherein the external heat preservation technology is to place heat preservation materials on the outer side of a building structure, the internal heat preservation technology is to place the heat preservation materials on the inner side of the building structure, and the two heat preservation technologies can achieve the heat insulation and heat preservation effects. Because the heat insulation material of the outer wall has higher requirements on weather resistance and durability, the loss can be serious, so that the current single heat insulation technology cannot meet the requirements of users, and the ceramic heat insulation technology of the inner wall is also becoming more important.
