Problems solved by technology

However, architectural ceramics, like other building materials, have never changed the "three highs" situation of high pollution, high energy consumption, and high emissions. At present, the total energy consumption of my country's building materials industry is second only to the electric power and metallurgical industries, and it has become a major energy consumer in my country. Consumption reduction situation is grim

Abstract

The invention discloses a low-temperature fired high-strength building ceramic green body, which is prepared from the following raw materials: 70 to 80 weight percent of basic green body, 1 to 8 weight percent of lepidolite, 5 to 10 weight percent of steel slag and 8 to 19 weight percent of andalusite, the basic blank is prepared from the following raw materials: 28 to 32 weight percent of chinastone, 10 to 12 weight percent of potassium feldspar, 6 to 14 weight percent of albite, 20 to 24 weight percent of kaolin, 8 to 14 weight percent of black mud, 12 to 16 weight percent of white mud and 1 to 3 weight percent of talc. In addition, the invention also discloses a preparation method of the low-temperature fired high-strength building ceramic green body. By optimizing a formula system, the breaking strength of the ceramic green body can be effectively improved, so that the thickness of a product is reduced, thin-wall light weight and low-temperature firing of the building ceramic green body are realized, the national strategy of green and sustainable development is met, and the ceramic green body has a wide market prospect.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a building ceramic body and a preparation method thereof. Background technique [0002] my country is a big country producing ceramics. In the past 10 years from 2007 to 2019, the output of China's architectural ceramics has increased from 5.010 billion m 2 Soared to 10.161 billion m 2 , the output doubled, ranking first in the world. However, architectural ceramics, like other building materials, have never been able to change the "three highs" situation of high pollution, high energy consumption, and high emissions. At present, the total energy consumption of my country's building materials industry is second only to the electric power and metallurgical industries, and it has become a major energy consumer in my country. The consumption reduction situation is grim. With the development of the times, especially the proposal of major social needs such as energy saving...
