A kind of porous brick with strong water absorption and its preparation method

Abstract

The invention discloses a perforated brick with strong water absorption property. The perforated brick comprises the following raw materials in parts by weight: 15-25 parts of limestone, 10-15 parts of waste ceramic tiles, 3-6 parts of lignin, 5-15 parts of feldspar powder, 15-25 parts of red stoneware shale, 40-50 parts of coal gangue, 8-15 parts of water; a preparation method of the perforated brick comprises the following steps: crushing, sealing and aging, preforming, drying and sintering to obtain hollow bricks which are strong in water absorption property and are fireproof and thermal-insulating; the perforated brick is high in compressive strength, and excellent in comprehensive property, and meets the national standard; the perforated brick is wear-resistant and anti-seismic, can be directly carried and stacked, and is high in finished rate; the perforated brick is energy-saving and emission-reducing, capable of preventing environment protection, and ecological and environmentally friendly; the production technology is simple, the production is convenient, the production period is short, wastes can be utilized, resources can be saved, the production cost is low, and the large-batch industrial production is favorable.

Description

technical field [0001] The invention relates to the field of building material production, in particular to a porous brick with strong water absorption and a preparation method thereof. Background technique [0002] The brick-making industry is an industry with high energy consumption, high pollution, high resource consumption and low output. Every brick and tile factory will receive the key care of the local environmental protection bureau. Now the production of porous bricks will consume a lot of resources, which is not in line with the principle of resource conservation. In principle, for example, the sintering temperature of most brick and tile factories is about 1300-1400 ℃, which consumes a lot of energy. In order to solve this problem, the engineering and technical personnel of the industry have taken many measures. Generally, enterprises take measures to widen and lengthen the kiln To achieve the purpose of saving energy and reducing consumption, in order to achieve ...

[0002] The brick-making industry is an industry with high energy consumption, high pollution, high resource consumption and low output. Every brick and tile factory will receive the key care of the local environmental protection bureau. Now the production of porous bricks will consume a lot of resources, which is not in line with the principle of resource conservation. In principle, for example, the sintering temperature of most brick and tile factories is about 1300-1400 ℃, which consumes a lot of energy. In order to solve this problem, the engineering and technical personnel of the industry have taken many measures. Generally, enterprises take measures to widen and lengthen the kiln To achieve the purpose of saving energy and reducing consumption, in order to achieve rapid firing, but the above method requires enterprises to invest a lot of money in the transformation of the kiln, and the space occupied by the kiln will also be limited to a certain extent, it is difficult to realize, and it is not available now It is allowed to excavate the soil and burn bricks. Now other substitutes are used to make bricks, which requires adding cement, which is costly. The porous bricks made of burnt bricks are not strong in water absorption, wear-resistant, pressure-resistant, and earthquake-resistant, and cannot meet the needs of society.
