Attapulgite shale river bottom sludge sintering insulating brick

Abstract

The invention discloses an attapulgite shale river bottom sludge sintering insulating brick. The technical scheme has the key points that the components of the attapulgite shale river bottom sludge sintering insulating brick consist of attapulgite clay mineral tailing powder, shale, river bottom sludge, gangue, pyroclastic rock mixture, bentonite mineral tailing powder, expanded perlite and strawpowder. The components of the attapulgite shale river bottom sludge sintering insulating brick are conveyed into a dual-stage vacuum brick press after being evenly stirred, and subjected to vacuum extruding molding and blank cutting to form the semi-finished product of the attapulgite shale river bottom sludge sintering insulating brick, and the semi-finished product is conveyed to a tunnel kiln after being naturally dried and is sintered to form the finished product of the attapulgite shale river bottom sludge sintering insulating brick. The attapulgite shale river bottom sludge sintering insulating brick has the characteristics of good strength, heat preservation, energy saving, soundproof property, heat insulation, and fireproof and flame retardant performances. The components of the attapulgite shale river bottom sludge sintering insulating brick disclosed by the invention adopt massive various wastes, not only the resource utilization rate is favorably improved, but also the wastes are changed into valuable, the occupied land is reduced, the environment is purified and protected, and the resource is saved. The attapulgite shale river bottom sludge sintering insulating 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 river bottom mud sintered thermal insulation 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 it...

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.
