Description

Metal Faced Vacuum Insulated Exterior Wall Insulation Panel

technical field

The utility model relates to a wall thermal insulation material, in particular to a metal surface vacuum thermal insulation outer wall thermal insulation board. the

Background technique

In recent years, with the rapid development of my country's building exterior wall insulation and exterior wall decoration technology, the fire protection problems of building exterior insulation systems and exterior wall decorations have become increasingly prominent. Cases of fires caused by improper measures have occurred frequently, which not only caused a certain degree of loss to the state and people's property, but also caused serious social impact. the

In the past, most of the external wall insulation boards used organic insulation materials, which had poor fire resistance. Now inorganic rock wool boards and glass wool boards are gradually used to replace the previous organic insulation materials. However, due to the strong water absorption of rock wool and glass wool, once the wall After the infiltration of internal moisture and outdoor rainwater, the bulk density increases, the heat transfer coefficient increases, and its own strength is weakened, unable to bear its own weight, causing natural gravity to sink, thus destroying the plastering layer. In addition, due to the limitation of the thermal conductivity of rock wool or glass wool, when it is necessary to achieve a lower heat transfer coefficient, the insulation board needs to be thickened, which increases the weight of the insulation board, increases the manufacturing cost and increases the difficulty of production, and at the same time, the safety factor also lowered. the

Utility model content

The technical problem to be solved by the utility model is to provide a metal-faced vacuum heat-insulating outer wall heat-insulation board which will not get damp, has low thermal conductivity and low cost. the

The technical solution of the utility model is to provide a metal surface vacuum heat insulation outer wall heat preservation board, which includes a sealing frame and a heat preservation layer composed of a metal plate. In the fireproof glass fiber aluminum foil cloth layer, the gap in the heat insulation layer is a vacuum. the

After adopting the above scheme, the metal surface vacuum insulation outer wall insulation board of the utility model is provided with a fireproof glass fiber aluminum foil cloth layer to seal the insulation layer and vacuumize the gap between the insulation layers, so that the insulation layer can be used without increasing the thickness. Under the circumstances, the thermal conductivity is reduced. In addition, because the insulation layer is sealed in the fireproof glass fiber aluminum foil cloth layer, it will not be affected by moisture. Compared with increasing the thickness of the heat preservation layer, the utility model only adds a layer of fireproof glass fiber aluminum foil cloth layer. The insulation layer is evacuated, so the cost is low. the

Preferably, the thermal insulation layer is any one or a combination of rock wool, mineral wool, and glass wool. the

As a preference, polyester glue is used to bond the fireproof glass fiber aluminum foil cloth layer to the heat preservation layer and the metal plate. the

Description of drawings

Accompanying drawing 1 is the schematic cross-sectional structure diagram of the metal surface vacuum heat insulation outer wall thermal insulation board of the present invention. the

As shown in the picture:

1. Metal plate, 2. Insulation layer, 3. Fireproof glass fiber and aluminum foil cloth layer.

Detailed ways

In order to better illustrate the technical solution of the utility model, the specific implementation of the utility model will be described in detail below in conjunction with the accompanying drawings. the

As shown in accompanying drawing 1, a kind of metal surface vacuum heat insulation external wall thermal insulation board, comprises the sealing frame and thermal insulation layer 2 that metal plate 1 is formed, and described thermal insulation layer 2 is also provided with fireproof glass fiber aluminum foil cloth layer 3, heat preservation Layer 2 is sealed in fireproof glass fiber aluminum foil cloth layer 3, the gap in the insulation layer 2 is a vacuum, and the insulation layer 2 is any one of rock wool, mineral wool, glass wool or a combination of more than one , the fireproof glass fiber aluminum foil cloth layer 3 is bonded with the thermal insulation layer 2 and the metal plate 1 with polyester glue. the

In the above-mentioned embodiment, a kind of best implementation mode of the present utility model has been described, obviously, under the inventive concept of the present utility model, still can make many changes and improvements, as described insulation layer 2 also can be Rock wool or mineral wool or glass wool, or a combination of rock wool and mineral wool or a combination of mineral wool and glass wool or a combination of rock wool and glass wool, or three types of rock wool, mineral wool and glass wool Compositions. The key of the utility model is to seal the insulation layer and vacuumize it. Here, it should be explained that any changes made under the inventive concept of the present utility model will fall within the protection scope of the present utility model. the
