Iron tailing based wave-absorbing radiation resistant porous light heat insulation brick for building face wall and preparation process of heat insulation brick

Abstract

The invention discloses an iron tailing based wave-absorbing radiation resistant porous light heat insulation brick for a building face wall and a preparation process of the heat insulation brick. According to the heat insulation brick, iron tailings and rare earth tailings are effectively utilized, rare earth elements in the rare earth tailings are used to be sintered with the iron tailings to form crystalline with high infrared blocking rates, adhesives and pore forming agents are compounded, so that mixing materials are more compact and the porosity is high, a green body is not prone to crack, no harmful gas is generated, the heat insulation and preservation capabilities of the brick body are effectively improved, nanometer spherical ferroferric oxide magnetic powder is added to endow the brick body with the efficacies of wave absorption and electromagnetic radiation resistance, the habitability of a building body is improved, and the heat insulation brick is especially suitable for heat insulation and preservation of a residential building wall surface.

Description

Technical field [0001] The invention relates to the technical field of heat-insulating bricks for buildings, in particular to an iron tailing-based wave-absorbing and anti-radiation porous lightweight heat-insulating brick for building facades and a preparation process thereof. Background technique [0002] Insulation brick is a kind of heat-insulating and light-weight refractory material with regular shape. It is widely used in the heat-insulating and heat-insulating engineering of building roof, inner and outer walls, and inner and outer roofs of building foundations on slopes. It is a very important The building materials, which greatly improve the internal temperature of the building, and improve the comfort of the residence. Among them, the light and porous foam insulation bricks are better than the traditional overhead insulation bricks and hollow insulation bricks. The effect and mechanical properties are more superior, which is the focus of the research on thermal insulat...

Problems solved by technology

"Study on the preparation process and structure of iron tailings sintered porous insulation materials" uses iron tailings as the main material, bentonite as the binder, and calcium carbonate as the foaming agent. It is sintered and prepared to have a certain heat insulation effect and load-bearing effect. However, the porosity of the prepared material is low, and the heat insulation effect still needs to be improved. It is acceptable for indoor heat insulation materials, but it cannot meet the demand for outdoor walls, especially roof walls, and its use is limited.
