Abstract

The invention provides a self-enhanced ceramic cold glaze and a preparation method thereof. The cold glaze is prepared by the following steps: preparing the following raw materials: phosphate / polyphosphates, meta-kaolin, silicon dioxide, zinc oxide, sodium silicate, an alkaline compound, and water, mixing raw materials according to a certain ratio, evenly stirring the mixture by a mechanical stirrer to form slurry, evenly painting the slurry on a blank, which needs to be decorated, and drying the blank at a room temperature or low temperature (40 to 100 DEG C). The glaze, which is obtained by the provided formula and preparation method, can be used to repair the glaze of blanks made of various porcelains. The glaze and the blank interface are well combined together. The glaze has excellent mechanical properties, the compressive strength can reach 150 MPa or more, the surface of the glaze is smooth, the color is white-grey and transparent, no defect exist on the surface, and the market needs can be met. Compared with the conventional glaze production technology, the provided preparation method has the advantages of simple technology, energy saving, environment-friendliness, low cost, and easy operation.

Description

technical field [0001] The invention relates to a self-reinforced ceramic cold glaze and a preparation method thereof, belonging to the field of inorganic non-metallic gelling materials. Background technique [0002] "Glaze" is a glossy glass-like thin layer covering the surface of the ceramic body. Its function is not only decorative, but also can improve the physical and chemical properties of the body surface, increase the hardness of the product, and increase its thermal stability. Based on the role of glaze on ceramic products, the importance of glaze in the ceramic industry is constantly being highlighted and enhanced, which directly affects the quality and cost of ceramic products. [0003] The traditional glaze technology needs to be fired at high temperature (~1350°C) and the firing period is long (14-16 hours). Although the glaze layer prepared by this method has strong mechanical properties and high gloss, the technical The harsh conditions and high energy consum...
