Attapulgite, shale and flyash sintered porous brick

Abstract

The invention discloses an attapulgite, shale and flyash sintered porous brick which is technically characterized in that the components of the brick comprise high-viscosity attapulgite clay powder, attapulgite clay tailing powder, shale powder, flyash, pyroclastic rock mixture and bentonite tailing powder. The attapulgite, shale and flyash sintered porous brick is prepared according to the following steps: stirring the components of the attapulgite, shale and flyash sintered porous brick uniformly, conveying into a double-stage vacuum brick making machine, extruding and forming in vacuum, cutting the adobe to obtain the semi-finished product, airing the semi-finished product naturally, conveying into a tunnel kiln, and sintering into the finished product which is the attapulgite, shale and flyash sintered porous brick. The attapulgite, shale and flyash sintered porous brick has the characteristics of high strength, heat preservation, energy saving and heat and sound insulation. Because the components of the brick provided by the invention include a large amount of waste, the utilization rate of resources is improved, the waste is changed into thing of value, less land is occupied, the environment is protected and purified, and energy is saved. The attapulgite, shale and flyash sintered porous brick is suitable for wall construction.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an attapulgite shale fly ash sintered porous brick. Background technique [0002] New wall materials mainly refer to building materials mechanized from non-clay resources such as sandstone, shale, industrial solid waste, and construction residual soil, which have the functions of protecting land, protecting the environment, saving energy, utilizing waste, increasing strength and economical Applicable and other characteristics, compared with solid clay bricks, shale bricks have the biggest advantages in that their production does not destroy cultivated land and consumes less energy, which is in line with the national technological development policy. [0003] Shale is a rock formed by the extrusion of clay in the crustal movement. It has sheet-like or thin-sheet bedding. It is easy to break into pieces when hit with a hard object. Shale is not viscous, and its plasticity and wate...

Problems solved by technology

[0009] The disadvantage of the above-mentioned patent is that "the raw materials are mixed according to the following parts by mass on a dry basis: shale, lime, and fly ash with a particle size of 1000-1500 mesh after crushing", and the particle size of 1000-1500 mesh is equivalent to 0.012-0.009 mm. The production cost of this kind of particle fineness is very high, and it cannot be applied to the actual production of the building materials industry.
