Abstract

The invention relates to the technical field of the manufacturing of ceramics, and provides a ceramic green body and a preparation method of a bright-convex-glaze ceramic. The ceramic green body is prepared from the following raw materials: potash feldspar, soda feldspar, quartz sand, porcelain clay, calcite, calcined talc, a brightener, aluminum oxide and zinc oxide. The ceramic green body has excellent mechanical performance. The preparation method comprises the following steps of mixing and grinding the raw materials for the ceramic green body into slurry, oven-drying, controlling humidity to form a ceramic green body basal powder, and then pressing to form the ceramic green body; carrying out first-time sintering; successively coating basal glaze and surface glaze on the surface of the ceramic green body; jetting ink towards the surface glaze by adopting an ink jet printing technique to carry out printing, so as to form a first decorative pattern design; oven-drying the first decorative pattern design; spraying bright-convex-glaze glaze towards the first decorative pattern design by adopting a screen printing technique, so as to form a second decorative pattern design; afterwards, carrying out second-time sintering. The bright-convex-glaze ceramic prepared and obtained by the preparation method can reach the visual effects of from the front, a whole range, and from the side, a single peak; far, near, high, low, no two parts alike.

Description

technical field [0001] The invention belongs to the technical field of ceramic manufacturing, and in particular relates to a preparation method of a ceramic green body and a bright convex glaze ceramic. Background technique [0002] From ancient times to the present, the manufacture of ceramics has a history of thousands of years, and ceramics are widely loved by people as living utensils and handicrafts. [0003] The printing on the surface of ordinary ceramic products cannot be refracted by light, and it is the same single pattern seen from any angle. If things go on like this, it will easily cause aesthetic fatigue. [0004] Therefore, it is an urgent problem to invent a kind of bright convex glaze ceramics capable of solving the above-mentioned problems and a preparation method thereof. Contents of the invention [0005] In view of the above-mentioned deficiencies in the prior art, the first object of the present invention is to provide a ceramic green body with excel...
