Description

A kind of insulation antibacterial interior wall Ceramic Tiles and preparation method thereof

Technical field

The present invention relates to building material field, particularly relate to a kind of insulation antibacterial interior wall Ceramic Tiles and preparation method thereof.

Background technology

Along with the development of science and technology, particularly the development of the energy, space technology, auto industry etc., more and more harsher to the requirement of material, in the urgent need to developing a kind of novel high performance structures material. And silicon carbide ceramics has, and elevated temperature strength is big, non-oxidizability is strong, mar proof is good, heat stability is good, thermal coefficient of expansion is little, thermal conductivity is big, hardness is high and the good characteristic such as anti-thermal shock and resistance to chemical attack is cognitive by people already, therefore, silicon carbide ceramics has been applied to multiple field as high performance structures material.

But the high covalency key in carborundum and low diffusibility make it be difficult to sinter when not having sintering aid and impressed pressure. The beginning of the seventies, Prochazka et al. is first using a small amount of B, C as additive, since obtaining the carborundum sintered body of densification when at 2100 DEG C with without any pressure, but SiC-B-C system belongs to solid-phase sintering category, need higher sintering temperature (> 2100 DEG C), this is accomplished by significantly high thermoelectricity energy consumption, and easily causes coarse grains and lack of homogeneity, make its fracture toughness relatively low, have stronger Crack Strength sensitivity. This high fragility and high sintering temperature limit the use of silicon carbide ceramics significantly. Therefore, the research that carborundum sinters has been forwarded in liquid-phase sintering by people, now it is clear that energy consumption not only can be greatly lowered by liquid-phase sintering, and can realize product densification.

Ceramic Tiles is by clay, quartz sand and other inorganic non-metallic raw materials, through tabular or the Bulk ceramic goods of the explained hereafter such as dispensing, ball milling, powder process, molding, sintering, is widely used in decoration and protection building, the metope of structures and ground. Along with the fast development of economy and improving constantly of living standards of the people, people are also more and more higher to the requirement of living environment. But, it is poor that current internal wall brick product yet suffers from heat insulation and preservation effect, and water absorption rate is high, intensity is low, many weak points such as is easily cracked, and without environmental protection characteristic, be there is harmful effect in human body etc., it is impossible to reach to purify air, do not meet the developing direction of modern materials for wall completely.
