Creamy white frit and preparation method thereof

Abstract

The invention relates to a creamy white frit, belonging to the technical field of ceramic. The creamy white frit comprises the components in parts by weight: 5-15 parts of potash feldspar, 15-25 parts of quartz, 15-25 parts of soda feldspar, 5-15 parts of dolomite, 1-3 parts of fine particle calcium carbonate, 8-15 parts of zinc oxide, 10-15 parts of zirconium silicate, 1-5 parts of potassium carbonate, 0.5-1.5 parts of sodium fluosilicate, 2-10 parts of boric acid, 0.5-2 parts of barium carbonate, and 1-5 parts of aluminum oxide. The preparation method of the creamy white frit comprises the steps of: mixing and stirring uniformly the components, melting in a 1500-1600 DEG C high-temperature frit furnace for 1.5-2.0 hours, and carrying out water quenching on the molten liquid with cold water to obtain the creamy white frit. The obtained frit has good fluidity, relatively low viscosity, good glossiness, higher flatness, and wider firing temperature; and the product quality is improved greatly and the product yield is increased.

Description

technical field [0001] The invention relates to a frit, in particular to an opalescent frit and a preparation method thereof, and belongs to the technical field of ceramic frit. Background technique [0002] Glaze quality is one of the main factors affecting ceramic products. The poor quality of white glaze is reflected in the lower whiteness of the glaze, poor gloss and more pinholes, which cannot meet the requirements of the product, and at the same time, reduce the quality of the product. , affecting the quality of ceramics. [0003] The key to the development of milky white glaze is to solve the common defects in the production of milky white glaze, such as high temperature viscosity, easy glaze shrinkage, orange glaze, patterned glaze, dull glaze and other defects. Therefore, in order to solve these defects of milky white glaze, domestic and foreign Most of the production of white glazed tiles uses frit glaze to improve the quality of the glaze surface. In order to...

[0003] The key to the development of milky white glaze is to solve the common defects in the production of milky white glaze, such as high temperature viscosity, easy glaze shrinkage, orange glaze, patterned glaze, dull glaze and other defects. Therefore, in order to solve these defects of milky white glaze, domestic and foreign Most of the production of white glazed tiles uses frit glaze to improve the quality of the glaze surface. In order to meet the needs of customers, some glaze companies have developed milky white frit glazes. Some milky white frits currently on the market either have poor whiteness or gloss Poor temperature, poor high-temperature fluidity, and narrow firing range have affected the quality of the product. Therefore, through continuous exploration and experimentation, a satisfactory milky white glaze formula should be optimized to eliminate various defects in production and improve the quality of the company's products. High quality, solve the technical problems of milky white glaze production, reduce glaze pinholes, improve glaze whiteness and gloss, and make product quality a step up
