Low temperature sintered environment-friendly glaze and preparation and use method thereof

Abstract

The invention relates to low temperature sintered environment-friendly glaze, which is prepared from the following ingredients in parts by weight: 28 to 34 parts of chalcedony, 12 to 17 parts of calcite calcitum, 8 to 14 parts of corallite, 7 to 12 parts of glaze stone, 19 to 22 parts of crushed gravel, 5 to 8 parts of anhydrous sodium sulphate, 15 to 18 parts of Guangxi white clay, 21 to 25 parts of sandstone, 8 to 11 parts of nickel oxide, 6 to 10 parts of sodium hydroxide, 7 to 9 parts of borax and 12 to 16 parts of silicon material. The silicon material includes crystalline-state silicon material and an amorphous-state silicon material, the crystalline-state silicon material is one or two of quartz sand or granite, the amorphous-state silicon material is one or two of bentonite, kieselguhr, natural clay or coal ash, and the mass content of the amorphous-state silicon material in the silicon material is higher than 30%. The glaze prepared by the formula has the characteristics of low sintering temperature, quick sintering speed, low production cost and small environmental pollution. Furthermore, the produced porcelain has strong glaze gloss, smooth and flat surface, stable performance and no glaze peeling phenomenon.

Description

technical field [0001] The invention relates to the field of environment-friendly materials, more specifically, relates to a low-temperature firing environment-friendly glaze and its preparation and use method. Background technique [0002] In the ceramic production process, it is necessary to burn fuel and calcined clay, blank material, glaze, etc., and a large amount of harmful gases are produced at high temperature, CO, SO 2 , nitrogen oxides, fluorides and soot, etc. At the same time, the waste gas emissions of ceramic enterprises are large, and the free SiO in the air and dust 2 If the content is high, the dust in the exhaust gas will have a high degree of dispersion, causing air pollution, acid rain, plant failure, etc., and more seriously, it will lead to serious consequences such as the greenhouse effect, sea level rise, and abnormal climate. One of the topics of close attention. At present, the sintering temperature of glaze is often higher than 1000°C, which cons...
