Abstract

The invention discloses an environment-friendly water-resistant shale hollow brick and a preparation method thereof. The hollow brick is prepared from the following raw materials in parts by weight: 26 to 30 parts of purple sand shale, 30 to 35 parts of coal gangue, 4 to 5 parts of fluorite tailings, 15 to 20 parts of ferruginous shale, 3 to 5 parts of rock sand crystals, 8 to 15 parts of ceramsite, 3 to 5 parts of asbestos powder, 5 to 8 parts of sepiolite powder, 5 to 7 parts of aluminum oxide, 2 to 4 parts of silicon carbide, 1.5 to 4 parts of titanium dioxide, 4 to 6 parts of crop straw powder, 1 to 3 parts of glass fiber, 8 to 15 parts of super absorbent resin, 1.5 to 3 parts of lignocellulose and 4 to 6 parts of anticorrosive paint. The raw materials are respectively subjected to crushing, dry mixing, wet mixing, aging, forming, painting, drying and daily maintenance to obtain a finished product. The wastes are used for being made into the hollow brick, so that the cost is reduced; the environment pollution is reduced; the prepared finished product has high water absorbing rate and excellent comprehensive performance.

Description

technical field [0001] The invention belongs to the field of building materials, and relates to a shale hollow brick, in particular to an environment-friendly and water-resistant shale hollow brick and a preparation method thereof. Background technique [0002] Hollow brick is the main wall material commonly used in the construction industry. Due to its advantages of light weight, high strength, heat preservation, and good sound insulation and noise reduction performance, it has become the first product recommended by the national construction department. Hollow bricks are made of clay, shale, etc. as the main raw materials, after raw material processing, molding, and sintering. The types of hollow bricks mainly include shale hollow bricks, sintered hollow bricks, clay hollow bricks, etc. Among them, the shale hollow bricks are made of shale as the main body, adding coal gangue, cement as the sticky substance, and mechanically pressurized. Material. [0003] With the devel...
