A sand-based breathing brick and its production method

Abstract

The invention relates to sand-based breathing bricks and a manufacturing method thereof, and belongs to the technical field of building material application. According to the manufacturing method of the sand-based breathing bricks, molding bricks obtained after natural maintenance are soaked in a humidifying sizing agent, and after the molding bricks complete adsorption, the breathing bricks are obtained after the molding bricks are subjected to drying and secondary maintenance, wherein the humidifying sizing agent is a mixture formed by a humidifying material, emulsion powder, a suspending agent and water according to a mass ratio of 0.8:0.15:0.05:100. According to the sand-based breathing bricks and the manufacturing method thereof, large amount of cheap materials of desert sand, flyash and mineral waste residue are used; in addition, the total content of the humidifying material kieselguhr is less than 8%, the utilization efficiency is high, and the humidifying performance is good; a foaming agent makes the inner parts of the sand-based breathing bricks have polyporous structures, thus the dry densities of the sand-based breathing bricks are reduced, and the thermal insulation properties of the sand-based breathing bricks are improved; meanwhile, through an organic combination with the humidifying material which has a polyporous structure in itself, the sand-based breathing bricks have compound polyporous structures, and the humidifying performance of the sand-based breathing bricks is sharply strengthened.

Description

technical field [0001] The invention relates to a sand-based breathing brick and a production method thereof, belonging to the technical field of building material application. Background technique [0002] With the development of the construction industry today, the building structure is mainly made of reinforced concrete, which determines that beams, slabs, and columns have been used as the main load-bearing objects of the building frame structure. Therefore, for the wall material that separates the interior space, it can meet the basic application requirements if it can bear its own weight. Clay bricks, which have been used for exterior wall filling and interior wall partition for a long time, will limit production due to many shortcomings in their production and use. Although the alternative porous bricks can meet the application requirements to a certain extent, their functions are single. The breathing brick has the functions of adjusting air humidity, purifying indoo...

Problems solved by technology

[0007] From the above representative patents, it can be seen that the function of existing breathing bricks is only for wall decoration. With the increase of building height, the frame structure has become the main structure in the construction field. The purpose of the wall is single function; and the content of diatomite in the breathing brick is relatively high, the mass percentage is more than 30%, and the highest reaches 90%.

The most important thing is that this kind of breathing brick is generally made by sintering process, and its sintering temperature is 850-1000 ° C for 20-30 minutes. At the same time, the sintering process not only greatly increases its production cost, but also easily produces new pollution to the environment
