Background technique

Since 1997, my country has enforced the implementation of building energy conservation, and one of the main measures is to insulate the outer protective structure. The current common practice is to add an insulation layer to the outer enclosure structure to control the heat transfer between indoor and outdoor, so as to achieve the purpose of building energy saving.

At present, organic and inorganic thermal insulation materials such as polystyrene board, extruded board and rock wool board are mostly used in the external thermal insulation system of building exterior walls in my country. These materials have good thermal insulation effects and can meet the thermal insulation requirements of various regions. However, organic The fire resistance of insulation materials is poor, and it is easy to quickly cause a large area of the wall to catch fire after a fire. The fire in the north of the CCTV new building was caused by the fire and rapid spread of the organic insulation materials in the insulation system; although rock wool has good insulation And flame retardancy, but its construction is difficult, and it will affect the decoration of the exterior wall.

Autoclaved aerated concrete sheet is a high-performance, porous concrete made of silicon and calcium as raw materials, aluminum powder (paste) as an air-generating agent, reinforced with anti-rust treated steel bars, and cured by high-temperature and high-pressure steam Formed sheet.

It is a new type of energy-saving building material strongly advocated by the state.

At present, there are some researches and introductions on aerated concrete insulation boards. For example, CA203684430U discloses an autoclaved aerated concrete insulation board. Insulation materials are wrapped inside the autoclaved aerated concrete sheet. The insulation board has Good thermal insulation performance, but the structure is relatively simple and does not have a decorative function. It needs to be plastered and decorated on the construction site, which affects the construction efficiency. Disclosed in CN203684442U is a light-weight sand aerated concrete fire-proof insulation board external wall insulation system, the system structure from inside to outside includes: concrete wall, aerated concrete adhesive, aerated concrete insulation board, interface agent, polymerization The anti-cracking mortar is pressed into the alkali-resistant glass fiber grid. As far as the aerated concrete insulation board is concerned, it only has the effect of heat preservation, but not the decoration function. Effectively improve construction efficiency.
