Abstract

The invention discloses a foaming ceramics material prepared through adopting polishing ceramic slags as a main raw material. The material is prepared through the following steps: mixing the following raw materials and water, wherein the raw materials comprise, by weight, 60-100% of polishing ceramic slags and 0-40% of an admixture; then carrying out compacting and forming, high temperature forming and puffing. The invention further discloses a preparation method for the foaming ceramics material. The foaming ceramics material provided by the present invention can replace the existing forming material, and has good fireproof performance and good heat insulation performance. In addition, the preparation cost is low.

Description

technical field [0001] The invention relates to a foaming material, in particular to a foaming ceramic material made of polished porcelain slag as the main material and a preparation method thereof. Background technique [0002] A large amount of ceramic solid waste slag will be produced in the production of ceramic industry, among which, the amount of polishing porcelain slag discharged by building ceramic factories during the polishing process of porcelain tiles is the largest. For example: there are more than 300 large-scale building ceramic factories in Foshan, Guangdong Province, with more than 2,000 production lines of various types, and the annual discharge of porcelain slag is more than 4 million tons. Among them, the amount of waste slag produced by a porcelain plate polishing production line is about 6-8 tons per day. In the past, these porcelain slags were mostly disposed of by stacking and landfilling. At present, the accumulated polishing porcelain slag has exc...
