Problems solved by technology

[0004] In the prior art, some researchers use calcium mineral calcite or stalactite to prepare high-calcium ceramics, but because the amount of calcite or stalactite is small, and the quality requirements for the rest of the ingredients are high; thus the cost of the ceramic product produced is relatively high. Large, low amount of pottery clay, such as patent publication number "CN103086697A" a method of using calcium mineral calcite or stalactite to prepare high-calcium ceramics; there are also researchers using purple sand shale and pottery clay mixture as clay raw materials to prepare ceramic products, However, due to the small amount of pottery clay, and the content of CaO and Fe2O3 in the pottery clay is

Abstract

The invention relates to the technical field of comprehensive utilization of mineral resources and in particular to a ceramic tile produced by pottery clay and a preparation method thereof. The preparation method is characterized in that by controlling and adjusting the raw material formula of the ceramic tile prepared from high-calcium pottery clay, combining the preparation process to grind high-calcium pottery clay raw materials and controlling and adjusting the granularity, active ingredients in the high-calcium pottery clay are improved and the performance of the high-calcium pottery clay raw materials is optimized; by combining treatment of initial bodies and semi-finished products after the compression molding process, each performance index of the green body before firing molding is optimized and controlled; after firing the semi-finished products in a kiln and controlling the firing temperature, low-energy-consumption firing is realized, and by combining control of the firing time, the strength and other mechanical properties of the prepared ceramic tiles are optimized. Therefore, the flexural and compressive strength of the obtained ceramic tile is 35.77-64.75 MPa, the water absorption rate of the ceramic tile is less than 1 percent, and ceramic tiles with excellent architectural decoration properties are further obtained.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of mineral resources, in particular to a ceramic brick produced by using clay and a preparation method thereof. Background technique [0002] Clay is a kind of mineral resource, which is relatively abundant in the world. Its ores are mainly purple-red and brown-red thick-layered massive calcareous siltstone, muddy siltstone, silty mudstone, and claystone. According to relevant detection data, there are relatively large clay resources in Guizhou and other southwest regions. In Yuqing, Guizhou, there are more than 80 million tons of clay resources, and the thickness reaches 280m, which can be used for a large number of open-pit mining. However, for the comprehensive utilization of pottery clay resources, there are still a lot of deficiencies in the prior art. The main reasons are: a large amount of pottery clay resources are of low grade, high-quality clay components, and their imp...
