Abstract

The invention discloses enamelled glass and relates to the technical field of glass processing. Glass matrix composition of the enamelled glass comprises components in percentage by mass as follows: 16%-20% of silica, 30%-32% of sodium silicate, 5%-7% of calcium carbonate, 12%-14% of lanthanum oxide, 21%-23% of calcium silicate, 3%-5% of aluminum oxide and 5%-7% of dolomite. By means of reconfiguration of composition proportion of the glass, internal network structure density of the glass is increased, the service life of the glass is prolonged, and impact resistance of the glass is improved.The invention further discloses a preparation method of the enamelled glass. The preparation method comprises following steps: A, mixing; B, melting; C, molding and cooling; D, screen manufacturing; E, screen printing; F, drying; G, baking and cooling; H, cleaning and drying. After application of glaze, a glass matrix is heated to be half-melting by means of high-temperature drying timing, the glaze is embedded in the inner layer of the glass, and therefore, retention time of glaze color is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a colored glaze glass and a preparation method thereof. Background technique [0002] Colored glaze, also known as overglaze color (such as five colors, pastels, etc.), is a ceramic coloring technique that draws patterns and fills colors on the glazed surface of fired porcelain, and then bakes it in a red furnace at low temperature. About 70°C ~ 80°C. In addition, painting on the plain body before firing the kiln, such as blue and white, underglaze red, etc., is called colored glaze, and its characteristic is that the color will never fade under the high-temperature glaze. [0003] Colored glazed glass is a decorative glass product obtained by printing inorganic glaze (also known as ink) on the glass surface by a certain process, drying the low-temperature glaze, and sintering the high-temperature glaze on the glass surface. High-temperature glazed glazed glass can be ...
