Sintered shale micropore building block and manufacturing method thereof

Abstract

The invention discloses a sintered shale micropore honeycomb glaze building block and a manufacturing method thereof. The manufacturing method includes: stirring and mixing raw materials comprising shale, building spoil, sludge, rubbish, straw (such as tree branches, leaves, rotten wood or tree), coal gangue, water, and the like to obtain a viscous mixture, extruding and forming to obtain a workblank of the building block, coating at least one side surface of the workblank of the building block with a clay layer and a glaze layer, sintering and forming. The building brick is manufactured by the method. The building block and the manufacturing method have advantages of low cost, short production period, low energy consumption, high building block strength, light unit weight, low heat conductivity coefficient, and good energy-conservation, heat insulation, sound insulation effects. The building block is provided with the glaze layer and can be directly used as a wall surface, thus shortening the building period, reducing cement consumption, reducing environment pollution, and avoiding hazards of dropping of external tiles. In addition, the building block and the manufacturing method achieve processing of the agriculture straw, the coal gangue, the rubbish, and other waste and turn the waste into things of value, thus achieving effects of energy conservation and environmental protection.

Description

technical field [0001] The invention relates to a building wall block, in particular to a sintered shale microporous block and a manufacturing method thereof. [0002] Background technique [0003] When modern buildings are built, wall bricks are usually pasted for decoration in the exterior wall technology. When pasting wall bricks, the specific process is generally to set an outer insulation layer on the outer wall of the block, then apply a layer of anti-crack mortar, then apply a layer of interface mortar and leveling mortar, and then paste the outer wall bricks. This traditional method has the following defects: [0004] 1. There are many processes, resulting in a long construction period. 2. A large amount of construction cement is consumed in each process. Construction cement is a highly polluting chemical product, and a large amount of carbon dioxide and dust will be released during the production process, which is one of the culprits leading to serious smog in mo...

AI Technical Summary

Problems solved by technology

[0004] 1. There are many processes, resulting in a long construction period

2. A large amount of construction cement is consumed in each process. Construction cement is a highly polluting chemical product, and a large amount of carbon dioxide and dust will be released during the production process, which is one of the culprits leading to serious smog in modern society

3. A large amount of construction waste will be generated. According to statistics, the external wall construction of traditional crafts will generate 1 cubic meter of construction waste per 100 square meters of external wall surface

4. This way of pasting the exterior wall tiles, after a long time, the exterior wall tiles are easy to fall off, resulting in potential safety hazards

[0005] Our patent application No. 200310100807.4 once disclosed a production method of a new type of building blocks. The produced building blocks have a decorative layer and can be used instead of wall bricks. Self-strength is poor

[0006] In addition, the existing blocks are generally solid blocks, which are small in size, large in bulk density and poor in thermal insulation, sound insulation and heat insulation. Mortar, resulting in a large amount of cement, also has the pollution problem caused by the production of cement

Some of the existing hollow blocks with sound and heat insulation functions generally obtain hollow air bubbles in the block by means of foaming. It is generated during the process of sintering, so that the heat insulation effect is formed during the sintering process. It takes more heat source to make the block burn through. At the same time, the air bubbles lead to uneven temperature distribution inside the block, which seriously affects the sintering quality of the block. block strength

[0007] In addition, in the vast rural areas, there are a large number of crop straws piled up, which cannot be handled, and pollution caused by burning.
