Method for preparing glaze self-releasing ceramic material by red mud and red sandstone

Abstract

The present invention discloses a method for preparing self glaze ceramic material; the molar percent of the raw material is that: 15-50 percent of red soil; 40-80 percent of red sandstone; 3-10 percent of molding material; the detailed steps are that: (1) the red soil and the red sandstone are put into a ball grilling tank for grilling; (2) the product obtained in step (1) is added with the molding material and then to be mixed in the ball grilling tank for grilling; (3) the product obtained in step (2) is taken with molding or pressed mode to form the mold and to become the blank body; (4) the blank body obtained in step (3) is baked for 0.5-3 hours under the temperature of 900 Celsius system -1350 Celsius system, and then to be cooled to the room temperature naturally to become the finished product. The finished product of the glaze level in the present invention is plump, smooth, bright and clear; the ceramic process degree from the blank body is much better; the raw material for the product is abundant; the cost is low; the technical process is simple; the advantages are good for solving the synthesized utilization problem for the red soil as well as enhancing the utilization ratio and utilization value for the red sandstone.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a method for preparing self-releasing glaze ceramic materials by using red mud and red sandstone. Background technique [0002] Red mud is a solid powdery waste produced during the process of refining alumina from bauxite. With the development of the aluminum industry, the annual accumulation of red mud in the world is increasing. The annual discharge of red mud in my country is more than 4 million tons. A large amount of red mud has not been effectively utilized, which has caused great harm to the environment and troubled the development of the aluminum industry. Therefore, the effective utilization of red mud has long been an urgent problem to be solved. [0003] Red sandstone is widely distributed and has large reserves in the Danxia landform area of ​​South my country. At present, red sandstone is mainly used as roadbed material. Red sandstone has high porosity, low natu...
