Problems solved by technology

[0002] Sintered bricks not only have a certain strength, but also have good heat insulation and sound insulation performance. There will be no condensation on the indoor wall in winter, and the current market price is low; although various new wall materials are constantly appearing, but Sintered bricks will still be used as a main material in masonry projects for a period of time in the future. The common fired bricks of the prior art are clay as the main raw material. Destruction, the sintering process consumes a lot of fuel and emits smoke, which wastes energy and pollutes the environment

Embodiment 1

[0017] A coal gangue porous sintered brick of the present invention is composed of the following raw materials in parts by weight: 45 kg of coal gangue; 35 kg of fly ash; 30 kg of shale;

[0018] The present invention also discloses a method for making coal gangue porous sintered bricks, which includes the following steps:

[0019] 1) Raw material processing: process all raw materials into powder, crush coal gangue to less than 1mm and separate pyrite;

[0020] 2) Stirring and mixing: the coal gangue powder, fly ash and shale powder from which the pyrite is separated are mixed evenly to make semi-dry mud;

[0021] 3) Compression molding: High pressure molding is adopted, and the molding pressure is 20~25Mpa;

[0022] 4) Drying: The formed billet is left to dry, and the drying time is 14 days;

[0023] 5) Sintering: place the dried bricks at 900-1100°C for 52 hours;

Abstract

The invention discloses a gangue porous sintered brick, which is composed of the following raw materials (by weight): 30-45 parts of gangue, 30-45 parts of fly ash and 20-35 parts of shale. The invention also discloses a manufacturing method of the gangue porous sintered brick, comprising the following steps: processing raw materials, stirring and mixing, compressing for moulding, drying and sintering. By the adoption of the technical scheme and by substituting shale for clay, cultivated farmland is avoided from being destroyed. By adding gangue, industrial waste residue can be fully utilized. The gangue can be spontaneously combusted during the sintering process. Then, vertical pores are formed. Therefore, weight per unit volume is reduced, and it is ensured that the brick has better sound insulation and thermal insulation effects. Dew formation will not occur to interior walls in winter. The brick is spontaneously combusted so as to reduce consumption of fuels, and good performance of the sintered brick is guaranteed.

Description

technical field [0001] The invention belongs to the field of building material production, and more specifically, the invention relates to a coal gangue porous sintered brick and a manufacturing method thereof. Background technique [0002] Sintered bricks not only have a certain strength, but also have good heat insulation and sound insulation performance. There will be no condensation on the indoor wall in winter, and the current market price is low; although various new wall materials are constantly appearing, but Sintered bricks will still be used as a main material in masonry projects for a period of time in the future. The common fired bricks of the prior art are clay as the main raw material. Destruction, the sintering process consumes a lot of fuel and emits smoke, which wastes energy and pollutes the environment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a coal gangue porous sintered brick that av...
