Process for producing coloured polished brick

Abstract

The invention discloses a method for preparing a colored polishing brick, comprising the existing traditional method for producing a polishing brick; the invention is characterized in that the waste iron tailing material is used for replacing part of glaze and blank material of the original polishing brick and added in the blank material and plus material of the polishing brick; and then the invention is prepared through a common process. The proportion of waste iron tailing material to the glaze and the blank material is more than 20 to 45 percent. By adopting the method for preparing the colored polishing brick by using the waste iron tailings, the method has the advantages of reducing production dependence on mineral material resource with excellent quality, improving utilization rate of the resource, diminishing discharge of solid waste, and greatly reducing the production cost of ceramic products; the used tailing replaces not only the ceramic mineral material, but also pigments, so that pigments only experience one calcining and heating process of ceramic roasting from the mineral to color forming; at the same time, the roasting temperature of the ceramics is decreased and roasting energy consumption of the ceramics is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of ceramic manufacture, and more specifically relates to a preparation method of colored polished tiles. Background technique [0002] Polished tiles are used in large quantities because of their glossy and smooth decorative effects. The raw materials of the polished tiles of the prior art include preparation through complicated production processes. For colored polished tiles, the cost of the used colored glaze At the same time, more energy is consumed in the production process; at the same time, most of the polished brick raw materials are taken from high-quality mineral resources, which will also have a certain impact on the environment during the production process. For example, the Chinese patent application number is 01114777, the application date is June 8, 2001, and the invention name is a patent application for cloud shadow stone polished brick and its manufacturing method. The formula weight ratio ...
