Abstract

The invention discloses glass containing copper oxide and a preparation method of the glass. The glass consists of the following raw materials in parts by weight: 10-20 parts of silicon dioxide, 10-30 parts of calcium oxide, 20-30 parts of potassium oxide, 40-50 parts of copper oxide, 50-60 parts of silver chloride, 60-65 parts of sodium phosphate, 35-38 parts of sodium pyrophosphate, 40-80 parts of sodium hypophosphite, 20-60 parts of sodium tripolyphosphate, 30-80 parts of dipotassium hydrogen phosphate, 40-60 parts of sodium acid pyrophosphate and 20-50 parts of titanium dioxide. The preparation method comprises the steps of uniformly mixing various raw materials and melting the raw materials; stirring until the raw materials are completely melted, decreasing temperature to 500-600 DEG C and taking out the glass liquid, and casting on a mold; annealing, keeping for 1-2 hours at 170-230 DEG C, decreasing temperature to 100-110 DEG C at 2-5 DEG C / hour, and naturally cooling. According to the glass disclosed by the invention, chemical stability of the glass is enhanced.

Description

technical field [0001] The invention relates to a glass, in particular to a glass containing copper oxide and a preparation method thereof. Background technique [0002] The glass has a variety of colors, energy saving and environmental protection, adding beauty to the interior and exterior, and can also insulate heat and cold, explosion-proof and shock-proof, keeping the room warm and adding safety insurance. Glass is a transparent semi-solid and semi-liquid substance that forms a continuous network structure when it is melted, and is a silicate non-metallic material that gradually increases in viscosity and hardens during cooling. The composition of ordinary glass chemical oxides (Na2O·CaO·6SiO2), the main component is silicon dioxide. Widely used in buildings, used for wind and light transmission, belongs to the mixture. There are also colored glass that is mixed with certain metal oxides or salts to show color, and tempered glass made by a special method. Sometimes s...
