Description

A new type of vacuum ultra-thin thermal insulation board

Technical field:

The utility model relates to a thermal insulation board, in particular to a novel vacuum ultra-thin thermal insulation thermal insulation board. the

Background technique:

With the advancement of science and technology, economic development and the strengthening of the awareness of environmental protection and energy saving in the whole society, people pay more and more attention to the insulation of building exterior walls. The use of external wall insulation technology to achieve building external wall insulation can make the room temperature and humidity of the building more stable, the human body has high comfort, and can protect the wall structure. Therefore, external wall insulation technology has gradually become the development of building external wall insulation. direction. While paying attention to the thermal insulation of building exterior walls, people also pay equal attention to the decorative effect of building exterior walls. the

At present, common exterior thermal insulation decorative panels used for building exterior wall insulation and decoration include decorative panels and thermal insulation panels, and the decorative panels and thermal insulation panels are bonded together. During construction, polymer cement mortar or other bonding materials are used to paste the exterior thermal insulation decorative board on the exterior wall of the building. According to the different methods adopted, it can be roughly divided into: polystyrene board thin plaster exterior wall insulation system; rubber powder polystyrene particle exterior wall insulation system; EPS board cast-in-place concrete upper exterior wall insulation system; mechanically fixed EPS steel wire mesh panel exterior wall External insulation system, etc. The above-mentioned thermal insulation system has the following limitations in varying degrees. the

1. The system has many links and poor reliability: each system uses materials with various properties, such as adhesive mortar, polystyrene foam board, metal anchors, steel wire mesh, mesh cloth and other materials with corrosion resistance and thermal expansion rate Materials with large differences make it easy to generate internal stress, which reduces the reliability of the entire system. On the other hand, the system has many processes. Insufficiency in each process may cause major quality hazards. the

2. While fulfilling the functional requirements of building thermal insulation, the system fails to meet the requirements of other performances: for example, the external thermal insulation system of the polystyrene board thin plaster exterior wall cannot completely solve the problems of cracking, water seepage or even falling off, and it is different from the base layer. Adhesiveness is not high, strength is low, insulation layer and protection layer are separated and other disadvantages, moreover paste ceramic tile, stone outside the existing insulation system, safety is insufficient. the

3. The system cannot be recycled and reused, and it is easy to generate construction waste. the

4. The outermost layer of the current insulation material is aluminum foil, and the inner material is not silicon dioxide, which is easy to fall off, so it is not suitable for use in the area north of the Yangtze River; and the fire protection coefficient of the insulation board used in the area north of the Yangtze River cannot meet the requirements. the

At present, there is a lack of a new type of vacuum ultra-thin thermal insulation board that can be used in various dry and wet environments in the south of the Yangtze River and in the north of the Yangtze River, and has a good thermal insulation effect. the

Utility model content:

In order to provide a novel vacuum ultra-thin thermal insulation board which is used in the south of the Yangtze River and the north of the Yangtze River, has a good thermal insulation effect and is not easy to be damaged. the

In order to achieve the above purpose, the present invention adopts the following technical solutions: a novel vacuum ultra-thin thermal insulation board, which is characterized in that: a glass fiber cloth composite film is wrapped with a silica board core. the

The outermost layer of the glass and the fiber cloth composite film is a glass fiber cloth layer. the

The inner layer of the glass fiber cloth composite film is a composite film with high barrier performance. the

The layers of the glass fiber cloth composite membrane are glued together. the

The silica plate core is wrapped with non-woven fabric. the

The upper and lower sides of the silica plate core are provided with glass fiber cotton layers. the

The insulation board is rectangular. the

The insulation board is square. the

The utility model adopting the above technical scheme is suitable for use in the areas south of the Yangtze River and north of the Yangtze River; the water absorption of silica is not good, and the pores between them are also small, so it is not affected by external humidity, etc., and is not affected by thermal expansion and cold contraction It can be used in the south of the Yangtze River and the north of the Yangtze River. It has good thermal insulation performance, and the fire coefficient reaches the national standard, which solves the current industry problems. the

Description of drawings:

Fig. 1 is a schematic cross-sectional view of the structure of the novel vacuum ultra-thin thermal insulation board described in the utility model:

Among them: 1. - Glass fiber cloth composite film; 2. - Silica plate core. the

Detailed ways:

Embodiments of the present invention are described below in conjunction with accompanying drawings:

The glass fiber cloth composite membrane 1 is wrapped with a silicon dioxide plate core 2 . the

The silica board core 2 has good thermal insulation performance and is not affected by humidity, so it is not easy to fall off in the future. the

The outermost layer of the glass fiber cloth composite membrane 1 is a glass fiber layer, the inner layer is a composite film with high barrier performance for vacuum insulation panels, and the layers are glued together. the

The layers are bonded by glue. Obviously, in addition to glue bonding, there are other ways of bonding, and the glue bonding here does not limit the specific implementation of the present invention. the

Described insulation board is rectangle, square. Of course, the shape can be other shapes, but it does not limit the specific implementation of the present utility model. the
