Abstract

The invention provides a method for preparing a microcrystalline glass ceramic composite bricks from waste glass, and relates to the field of building materials. The method comprises the following steps: preparing microcrystalline glass sheets; preparing nano ceramic sheets; preparing a middle layer powder; sequentially introducing the microcrystalline glass sheet, the middle layer powder, the nano ceramic sheet, the middle layer powder and the microcrystalline glass sheet into a mould, carrying out hot-pressing lamination in a hot-pressing furnace, wherein firstly, carrying out hot pressing at 800 to 850 DEG C and 6 to 8MPa for 5 to 10min, then carrying out hot pressing at 1180 to 1200 DEG C and 15 to 18MPa for 20 to 30min, and then carrying out pressure relieving, cooling, discharging, and demoulding to obtain the composite bricks. The microcrystalline glass ceramic composite bricks disclosed by the invention are excellent in various mechanical properties, good in chemical stability,high in surface gloss, and possesses wear resistance and frost resistance.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a method for preparing a glass-ceramic composite brick by using waste glass. Background technique [0002] Glass-ceramic is also called microcrystalline jade or ceramic glass. It is an inorganic non-metallic material. It is synthetic glass, which is a new type of building material just developed by foreign countries. Its scientific name is glass crystal. Glass-ceramic looks very different from our usual glass. It has the dual characteristics of glass and ceramics. The atomic arrangement inside ordinary glass is irregular, which is one of the reasons why glass is fragile. Glass-ceramics, like ceramics, is composed of crystals, that is to say, its atomic arrangement is regular, so glass-ceramics has higher brightness than ceramics. [0003] Glass-ceramic composite board is also called composite micro-ceramic stone. Composite micro-ceramic stone is a new type of composite plate...
