Problems solved by technology

[0002] At present, the load-bearing exterior walls of brick-concrete structures in the cold northern regions are mostly made of clay porous bricks, and the masonry itself cannot meet the requirements of external thermal insulation.
Therefore, it is necessary to add external thermal insulation materials on the external wall, mainly polystyrene boards. This external thermal insulation system has a good thermal insulation effect, but at the same time there are many insurmountable shortcomings: First, the waste of resources and energy is large, and the cost is high
Second, poor air permeability
The third is to cause white pollution in the later stage
Fourth, the frost resistance is poor, and after two winters, peeling begins to appear, and the service life is short
In addition, some thermal insulation materials can indeed play a role in thermal insulation, but due to their poor load-bearing performance, it is difficult to use them as load-bearing wall masonry.

Embodiment 1

[0010] Example 1, this kind of insulation brick, before firing the insulation brick, the weight content of its various components is 10%-30% of ceramsite ceramsite powder, and the main chemical component is sio 2 、fe 2 o 3 、Al 2 o 3 Shale powder 47%-67%, coal powder 5%, water 18%.

[0011] The production process of the above-mentioned insulation bricks is, in the first step, the main chemical composition is sio 2 、fe 2 o 3 、Al 2 o 3 The shale is crushed with an impact crusher, and the shale particles with a particle size of 3-25mm are screened by vibration and put into the rotary kiln for preheating. The preheating temperature is 300-400°C and the preheating time is 10-20 minutes. , after preheating, carry out high-temperature swelling at a temperature of 1150-1200°C for 5-10 minutes, and then burn it into ceramsite ceramsite, and then leave the kiln; The rock and coal are crushed into powder; the third step is to pour the ceramsite ceramsite powder, shale powder, coa...

Abstract

The invention discloses an insulated brick and manufacturing technique, which comprises the following parts: 10%-30% ceramic grain slag, 47%-67% shale powder with SiO2, fe2O3 and Al2O3, 5% coal dust and 18% water. The manufacturing technique comprises the following steps: 1. breaking shale grain; placing the shale grain into rotary kiln to preheat; bulking the grain under high temperature; sintering into ceramic grain slag; 2. grinding ceramic grain slag, shale and coal dust into powder; 3. stirring ceramic grain slag, shale, coal dust and water into blender according to certain proportion; 4. pouring brick mud into brick making machine to make brick blank; 5. piling brick blank into three-core arc-straight channel to sinter; 6. cooling; obtaining the product.

Description

Technical field [0001] The invention relates to a thermal insulation brick for building and a production process thereof. Background technique [0002] At present, the load-bearing exterior walls of brick-concrete structures in cold northern regions are mostly made of clay porous bricks, and the masonry itself cannot meet the requirements of external heat preservation. Therefore, it is necessary to add external thermal insulation materials on the external walls, mainly polystyrene boards. This external thermal insulation system has a good thermal insulation effect, but at the same time there are many insurmountable shortcomings: First, it is a waste of resources and energy, and the cost is high. The second is poor air permeability. The third is to cause white pollution in the later stage. Fourth, the frost resistance is poor. After two winters, peeling begins to appear, and the service life is short. In addition, there are also some thermal insulation materials that can i...
