Abstract

The invention discloses a porous ceramic-microcrystalline glass composite insulation decorative plate and a preparation method thereof. The porous ceramic comprises ceramic tile raw material, additive, pore forming agent and foaming agent, and the microcrystalline glass comprises SiO2, CaO, ZnO, Al2O3, Na2O, K2O, etc. The preparation method comprises the following steps: firstly uniformly mixing ceramic tile raw material, additive, pore forming agent and foaming agent, and conducting ball milling to obtain an ultrafine powder slurry; then granulating, drying, and conducting compression molding; drying the green ware body and then sintering in a roller kiln or a shuttle kiln; then, melting quartz sand, limestone, soda ash and other minerals or chemical raw materials to obtain a glass melt, carrying out water quenching on the glass melt to obtain glass particles; screening the dried glass particles and then classifying, paving on the surface of a porous ceramic plate, then pushing into a crystallization kiln to sinter, crystallize, anneal and cool the glass particles to form a microcrystalline glass layer; in the process, simultaneously compounding the microcrystalline glass with the porous ceramic plate to form the porous ceramic-microcrystalline glass composite insulation decorative plate.

Description

technical field [0001] The invention relates to a composite thermal insulation decorative board and a preparation method thereof, in particular to a composite thermal insulation decorative board of porous ceramics and glass-ceramic and a preparation method thereof. Background technique [0002] Glass-ceramic decorative panels have excellent physical and chemical properties such as wear resistance, non-absorbent, acid and alkali corrosion resistance, high strength, and good appearance decoration effects. They are widely used in architectural decoration, chemical industry, metallurgy and other fields. However, at present, my country's building energy consumption has accounted for 30% of the total energy consumption, and building energy conservation has become the focus of energy conservation and emission reduction. It is of great significance to develop new thermal insulation and energy-saving wall materials and improve the thermal insulation performance of external walls to a...
