Abstract

The invention discloses a method for preparing imitated jade glass utilizing cullet. Firstly, in percentage by mass, the following raw materials of 10 to 20% of SiO2, 30 to 40% of B2O3, 5 to 8% of Al2O3, 2 to 4% of MgO, 8 to 15% of Na2O, 5 to 10% of K2O, 2 to 10% of CaO, 5 to 15% of ZnO and 0.2 to 0.5% of Sb2O3 are accurately weighed and are uniformly mixed, and the mixture is molten for 2 to 3 hours at a temperature of 900 to 1,100 DEG C to obtain glass molten liquid; then colored cullet is crushed and sieved after being washed and dried, and glass fragments with diameters of 30 to 50mm are selected to be tiled in a fire-resistant die; finally, the glass molten liquid is poured onto the tiled glass fragments at a uniform speed at a high temperature until the glass molten liquid spills over the glass fragments; next, the obtained product is rapidly placed into an annealing furnace with the die for carrying out annealing processing so as to obtain an imitated jade glass blank, and after the imitated jade glass blank is cut, chamfered and polished, an imitated jade glass finished product is obtained.

Description

technical field [0001] The invention relates to a building decoration material, in particular to a method for preparing jade-like glass by using broken glass. Background technique [0002] It is well known that a large amount of cullet is generated during the production, processing and use of glass. According to the survey, there are hundreds of glass production enterprises in my country, and the damage of daily-use glass alone is about 2 million tons every year. Foreign developed countries attach great importance to the recycling of broken glass. For example, the utilization rate of Germany is 54%, that of Italy is 44%, and that of the Netherlands is as high as 66%, while the recycling rate of broken glass in my country is only about 10%. As a renewable resource for sustainable use, broken glass not only wastes very limited energy and raw materials, but also causes new hazards to soil and groundwater. If it can be fully utilized, it will play an important role in saving r...
