Preparation method of thermal-insulation microcellular foam ceramic tiles made of industrial wax powder

Abstract

The invention discloses a preparation method of thermal-insulation microcellular foam ceramic tiles made of industrial wax powder. The preparation method comprises steps as follows: powder with the diameter not larger than 1 mm is prepared from industrial wax; china clay and crushed industrial wax are mixed uniformly in the mass ratio being 1: (0.3-1), a proper amount of water is added for wetting, and the mixture is guided into a mold to be pressed and formed; formed tiles dry in the shade until the fracture surface doesn't have shadow marks, and cracking due to exposure at the high temperature is prevented; the formed tiles drying in the shade are put in a furnace and fired at the temperature of 300-1,200 DEG C for 3-12 h, and the ceramic tiles are formed. Through high-temperature firing, dewatered industrial wax powder and similar materials can be carbonized and pulverized, shrink and disappear at a certain temperature, a large quantity of sealed small holes are formed in the ceramic tiles, the thermal insulation function of the ceramic tiles is realized, and the thermal-insulation microcellular foam ceramic tiles have the thermal insulation effect with the thermal conductivity coefficient ranging from 0.050 W / (m.k) to 0.10 W / (m.k), a unique decoration effect, the water absorption rate within 0.03%, good wear resistance and small chromatic aberration.

Description

technical field [0001] The invention belongs to the field of building thermal insulation materials, in particular to a method for preparing industrial wax powder microporous foam thermal insulation tiles. Background technique [0002] Because tiles in the prior art have the following disadvantages: [0003] Easy to wear: Whether it is ceramic tiles or quartz tiles, the surface wear resistance is very low. Usually, after the tiles are laid, the side seams will be worn for about 6 months when used in the family, and the surface of the tiles will basically have different degrees of wear after 8-12 months; generally, the tiles used in public places will wear off within 2-3 months. The edge seams are worn out, and the tiles are worn to varying degrees within 6 months. [0004] Chromatic aberration: No matter how good the tiles are, there will be chromatic aberration, which is an unavoidable problem, mainly due to the limitations of raw materials and production processes. If ...
