Abstract

A green and environment-friendly brick is characterized by being prepared from the following raw materials in parts by weight: 25-35 parts of kaolin tailing powder, 20-40 parts of gangue powder, 15-20 parts of attapulgite, 8-15 parts of andalusite powder, 3-6 parts of nanometer alumina, 5-8 parts of nanometer magnesia, 1-4 parts of nanometer titania, 3-5 parts of silica powder, 9-12 parts of zirconia powder, 6-10 parts of silicon nitride powder, 6-10 parts of graphite powder, 3-8 parts of silicon carbide powder, 1-5 parts of cerium oxide powder, 2-5 parts of chromic oxide powder and 3-5 parts of stainless steel fibre. Environment protection is realized, and a brick body is enabled to have better performance characteristics.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to an environmentally friendly brick. Background technique [0002] Traditional fired bricks mainly use clay as raw material. However, with the continuous development of the construction industry, the demand for bricks is gradually increasing, and the existing clay resources can no longer meet the needs of brick making, coupled with the continuous strengthening of environmental protection in our country. Therefore, it is an urgent problem to develop an environmentally friendly brick that uses other raw materials instead of clay and has higher performance. Contents of the invention [0003] By adjusting the raw material composition of the brick body, the present invention uses kaolin tailings powder, coal gangue powder, attapulgite and andalusite as main raw materials on the one hand, and simultaneously adds components such as nano-alumina, nano-magnesia, and nano-titanium ...
