Pink glass-ceramic plate and production method thereof

Abstract

The invention discloses a pink glass-ceramic plate and a production method thereof. The pink glass-ceramic plate comprises the following components in parts by weight: 2-4 parts of Na2O, 8-11 parts of MgO, 9-11 parts of Al2O3, 55-70 parts of SiO2, 1-3 parts of P2O5, 3-4 parts of K2O3, 6-10 parts of CaO and 0.5-1.5 parts of Co2O3. The production method comprises the following steps: mixing the following materials in parts by weight: 24-31 parts of dolomite, 65-78 parts of granite, 2-6 parts of calcium dihydrogen phosphate, 0.5-1 part of cobalt sesquioxide and 2-4 parts of caustic calcined magnesite, and then producing by adopting all-electric melting calendering. According to the invention, the formula of the pink glass-ceramic plate is obtained by researching the proportion of a glass-ceramic plate for a long term, and the production method for producing the pink glass-ceramic plate is obtained. The pink glass-ceramic plate disclosed by the invention breaks through the condition of single color of the traditional glass-ceramic plate.

Description

technical field [0001] The invention relates to a building material and a production method thereof, in particular to a pink glass-ceramic plate and a production method thereof. Background technique [0002] Glass-ceramic not only has the basic properties of glass, but also has the polycrystalline characteristics of ceramics. It combines the characteristics of glass and ceramics and becomes a unique new type of material. Because of its high mechanical strength, high hardness, good wear resistance, strong corrosion resistance, good chemical stability and thermal stability, and can adapt to harsh environments, it has developed rapidly in the world in recent years. In particular, the "Twelfth Five-Year New Material Industry Development Plan" announced by the Ministry of Industry and Information Technology in January 2012 included rolled glass-ceramic in the list of inorganic non-metallic new materials that will be developed as a key development, and has a great impact on the de...

Problems solved by technology

[0003] The traditional glass-ceramic production mostly adopts the sintering process. The high energy consumption of the sintering process in the production of glass-ceramics has always been a key bottleneck restricting the rapid development and large-scale production of glass-ceramics.

[0004] At present, beige and brown glass-ceramic plates are produced by using the waste granite by the full electric fusion calendering process, but the beige and brown glass-ceramic plates are difficult to meet the market's demand for multi-variety and multi-color glass-ceramics. Therefore, it is necessary to continuously study the formula and production process of glass-ceramics of different colors
