Problems solved by technology

The emulsifying agent needs to grind calcium carbonate and titanium dioxide separately, continue to grind after mixing, and disperse after drying. The preparation process of the emulsifying agent is time-consuming and consumes a lot of power, which is not conducive to the realization of industrialization; and the emulsifying agent requires It is further mixed with quartz, potassium feldspar, aluminum oxide, calcite and other components to form a glaze, and the glaze should be ball milled for 18-22 hours to control the fineness of the glaze slurry to about 200 mesh; the glaze slurry is sieved twice, and removed twice Iro

Abstract

The invention discloses a preparation method of reflective heat-insulation ceramic glazed tiles. The preparation method includes mixing frit raw materials, and founding the frit raw materials in a frit furnace into frits at a founding temperature of 1400-1600 DEG C until the raw materials fuse completely; mixing the frits with a raw material with grinding to obtain glaze slip, wherein the frits account for 10-100% of the total mass of the raw materials, and the content of titanium dioxide in the glaze slip is not lower than 8% of the total mass; applying the glaze slip on green bodies; drying the green bodies with the glaze slip, and firing at a temperature of 1100-1250 DEG C so as to obtain the reflective heat-insulation ceramic glazed tiles. The preparation method has the advantages that the frits are mixed with a specific amount of raw material, and enamel layers with titanite crystals as a main crystal phase are formed on the surfaces of the ceramic glazed tiles and are capable of reflecting sunlight reflectively, so that absorption of the ceramic glazed tiles for solar heat radiation can be reduced effectively, and building energy consumption of hot-summer and warm-winter regions is reduced remarkably; the preparation method is low in preparation cost and remarkable in energy-saving and environment-friendly effects.

Description

technical field [0001] The invention relates to the field of building ceramics, in particular to a preparation method of a reflective and heat-insulating ceramic glazed tile. Background technique [0002] Building energy consumption is one of the three main energy consumption modes in my country, which is side by side with transportation energy consumption and industrial energy consumption. With the development of society and economy and the improvement of people's requirements for indoor environment comfort, building energy consumption has shown a rapid upward trend, and the proportion of energy consumption in the whole society has continued to rise. [0003] Using various methods to reduce or prevent building heating caused by strong solar radiation, reduce cooling energy consumption, and reduce environmental pollution has become an important research goal of building material energy conservation. As the most important part of building energy consumption, the thermal insu...
