Abstract

The invention discloses a low-temperature melting block finished glaze and a preparation method thereof. The low-temperature melting block finished glaze is prepared by uniformly mixing the following materials in parts by weight: 90-94 parts of low-temperature melting block and 6-10 parts of kaolin, wherein the low-temperature melting block comprises mineral materials, mineralizing agents and fluxing agents; the mineral materials are industrial quartz and aluminium hydroxide; the mineralizing agents are potassium carbonate, lithium carbonate and lithium fluoride; and the fluxing agents are calcium carbonate, zinc oxide, boric acid, sodium borate and red lead. In the low-temperature melting block finished glaze prepared by the invention, qualified ceramic can be glaze-fired at the temperature of 850-900 DEG C, so that the temperature resistance requirement on kiln furnace equipment is reduced, the energy consumption of a ceramic product is reduced, further the manufacturing cost is reduced and ceramic pigment generates brighter color on the ceramic product.

Description

Technical field [0001] The invention relates to the technical field of frit glaze for ceramic products, in particular to a low-temperature frit finished glaze and a preparation method thereof. Background technique [0002] At present, in the production of ceramic products, most of the firing of ceramic products uses secondary firing: primary firing and primary glaze firing. In order to achieve the purpose of energy saving, many businesses have conducted research on how to reduce the firing temperature during the ceramic glaze firing process. Since the 1970s, the firing temperature of ceramic products has dropped significantly, saving a lot of precious energy and ensuring the continuous and stable development of the ceramic industry. [0003] A low-temperature biscuit firing and a high-temperature glaze firing process are adopted. When the high-temperature glaze is fired, the bisque-fired inside will volatilize, so that pinholes will appear on the surface of the product, resulting i...
