Abstract

The invention relates to a preparation method of an environment-friendly blue brick and belongs to the field of building wall materials. The preparation method comprises the following steps: (1) raw material pretreatment; (2) batching and stirring: weighing shale, clay, sludge, waste ceramics, vermiculite, volcanic ash, bean curd swilling, pine barks, bamboo residues and carbon according to the proportion occupied by all the raw materials, adding a proper amount of water, stirring the raw materials and uniformly mixing to obtain a mixture; (3) digesting; (4) pressing and molding: pressing and molding the digested mixture to obtain a brick blank, and naturally airing the brick blank till the moisture content is 16-20 percent to obtain the air-dried brick blank; (5) brick blank sintering: enabling the air-dried brick blank to enter a kiln for firing and sintering for 8-10 hours at a temperature of 1050-1250 DEG C; (6) sealing the kiln and cooling. According to the preparation method of the environment-friendly blue brick, the cost can be reduced, and safety and environmental protection are realized.

Description

technical field [0001] The invention relates to building wall materials, in particular to a preparation method of environment-friendly blue bricks. Background technique [0002] In the traditional firing process, clay is mainly used as raw material. After the blank is formed, it is fired in a kiln to make green bricks or blue tiles. For excessive use of clay, the government has taken relevant compulsory measures to prohibit the use of clay as raw material for the production of building materials. The cycle of making blue bricks or blue tiles is long and the cost is high. [0003] Most of them are prepared by adding coal raw materials such as coal gangue in the preparation process of existing bricks. Coal is the most important energy in our country. With the continuous production and expansion of the coal industry, the amount of coal gangue produced is increasing day by day. The amount of coal gangue produced is calculated as 15% of the raw coal output, and the annual incre...
