Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building wall panels, and more specifically to a high-efficiency ultra-thin autoclaved aerated concrete composite thermal insulation wall panel. Background Art
[0002] With the increasing requirements for building energy conservation, the insulation layer is getting thicker and thicker. This makes the production and installation of wall panels more and more difficult and uneconomical. Too thick wall panels also reduce the usable area and increase the shared area, resulting in a waste of social resources. How to reduce the thickness of wall panels while meeting the requirements for building energy conservation is a direction for the next step in building wall panel manufacturing.
[0003] The vacuum insulation board used for building exterior wall insulation is an excellent insulation material. With the maturity of technology, it has been well applied in building insulation. Its thermal conductivity is extremely low, only 0.002, which is 1 / 20 of EPS foam board and 1 / 12 of polyurethane insulation board. A 20mm thick vacuum insulation board can achieve the insulation effect of 240mm thick polyurethane. The production process of vacuum insulation board is to vacuum seal the insulation core board in aluminum foil composite glass fiber cloth or aluminum foil composite non-woven fabric (bag), and the sealing is done with hot melt adhesive. However, the temperature of hot melt adhesive is only 70-150 degrees Celsius. In a high temperature environment, such as the production process of autoclaved aerated concrete, the hot melt adhesive will melt and destroy the vacuum insulation layer, thereby losing its insulation performance.
[0004] Therefore, how to provide a lightweight concrete composite insulation wall that can seal the vacuum insulation panel and compound it with autoclaved aerated concrete without being affected by high temperature, destroying the vacuum, and reducing the insulation effect, thereby greatly reducing the thickness of the wall panel and making the production, installation, and use of the wall panel simple, convenient, and efficient is one of the technical problems that need to be urgently solved in this field.

[0007] A highly efficient ultra-thin autoclaved aerated concrete composite thermal insulation wall panel, the autoclaved aerated concrete composite thermal insulation wall panel comprises a base plate, an FRP mesh cage and an insulation layer arranged in the base plate, the insulation layer is also located inside the FRP mesh cage; the insulation layer is a fiber-reinforced (hollow) vacuum insulation layer, and the fiber-reinforced vacuum insulation layer is fixedly connected to the inside of the FRP mesh cage through a connector; the vacuum insulation layer is an internally hollow and vacuum insulation board composed of one or more vacuum insulation boards bonded by glass fiber cloth through unsaturated resin, and the glass fiber cloth and the vacuum insulation board are bonded together without gaps.
