Abstract

The invention discloses a building ceramic tile with a heat reflection function. The building ceramic tile comprises a green body layer, a surface glaze layer, a high reflection layer, a protective layer and a transparent glaze layer from bottom to top, wherein the high-reflection layer comprises a nano composite material of Mo and one or more of Ag, TiO2 and Y2O3; wherein the protective layer comprises SiO2; the high-reflectivity nano composite material of Mo and one or more of Ag, TiO2 and Y2O3 is applied to the surface glaze layer, the low-reflectivity SiO2 is added to the protective layer,the ceramic tile is endowed with a heat reflection function, and microprisms are randomly applied to the protective layer, so that a multi-reflection effect is achieved; the building ceramic tile with the heat reflection function has a very strong reflection effect on ultraviolet rays and extreme ultraviolet rays, the reflectivity can reach 80% or above, an obvious heat insulation effect is achieved, and the indoor temperature can be reduced by 5-10 DEG C.

Description

technical field [0001] The invention relates to the technical field of building tiles and a preparation method thereof, in particular to a building tile with heat reflection function and a preparation method thereof. Background technique [0002] The urbanization process has gradually increased the impact of the heat island effect, and the average daytime temperature in many cities is higher than that in surrounding suburban areas. In the south, especially in South China, where summer is hot and winter is warm, in hot weather, a large amount of radiant heat enters the room and the temperature continues to rise, making the working and living environment extremely uncomfortable. In this way, in the extremely hot summer, staying in an air-conditioned room is the choice of most people. However, if you stay in an air-conditioned room for a long time, the human body will easily feel tired, lethargic, and bored. It is easy to cause a cold and reduce people's work efficiency and he...
