Problems solved by technology

These systems all use organic foam insulation materials as the heat insulation material of the whole system. Various gas foaming agents are used in the production of organic foam materials, and these foaming agents will diffuse out of the cells, causing The thermal resistance of the material decreases (experiments abroad have proved that the thermal resistance of some organic foam insulation materials has decreased by 30% within 3 months after production), which reduces the energy-saving effect of the entire external thermal insulation system, failing to meet the design and Building energy-saving requirements; in addition, the

Embodiment 1

[0031] Example 1: As shown in Figure 1, it is an exterior wall thermal insulation composite layer with a mortar facing layer, which includes mineral wool board 1, anchor 2, glass fiber mesh cloth 3 and facing layer 4, mineral wool board 1 Adhere to the outer wall 6 through the bonding mortar 5, and the anchor for reinforcement 2 penetrates the mineral wool board 1 and inserts into the outer wall 6, in order to flatten the installation surface, first coat the outer side of the mineral wool board There is a leveling layer 7, the glass fiber mesh cloth 3 is used as a reinforcement layer to cover the leveling layer 7, and the silicone resin paint is sprayed on the outside of the glass fiber mesh cloth 3 as the facing layer 4. Of course, other mortar materials known in the art can also be used as the finishing layer and sprayed on the outermost layer.

Embodiment 2

[0032] Example 2: As shown in Fig. 2, it is an exterior wall external thermal insulation composite layer with the finishing layer 4 being a plane. The difference from Example 1 is that a putty leveling layer 8 is added outside the glass fiber mesh cloth 3. The silicone resin paint is applied to the outermost layer. Of course, other paints known in the art can also be used as the finishing layer to be applied to the outermost layer.

Embodiment 3

[0033] Example 3: As shown in Figure 3, it is an exterior wall external thermal insulation composite layer where the finishing layer 4 is a ceramic tile. The difference from Embodiment 2 is that the outermost finishing layer 4 is replaced by a ceramic tile. The binding agent 9 is adhered to the glass fiber mesh cloth 3, and the gaps between the tiles are filled with the tile grout 10.

[0034] The mineral wool board 1 in the above three embodiments can be rock wool board, slag wool board or glass wool board, or other types of mineral wool board.

Abstract

The invention discloses an external heat-insulating composite layer for external walls and the external insulation system of external walls. The mineral cotton boards of composite layer is bonded on the external wall through the binding mortar, the rivet components for reinforcing inserts the external walls through the mineral cotton boards, the outside of mineral cotton boards is equipped with glass fiber grid fabric, and the decorative layer is installed on the outside of glass fiber grid fabric. Mineral cotton boards could be rock cotton board, silicate cotton board or glass cotton board. The external insulation system of external walls is the main body of the building out walls, the edgings of windows and doors use mineral cotton board heat-insulating composite layer and the other parts use the prior heat-insulating composite layer. The invention uses the mineral cotton boards belonging to inorganic materials as the main structure of external heat-insulating layer, so the external heat-insulating layer has many advantages of not combustion, stable thermal resistance properties, not contraction and '' breathing '', it overcomes the defects of organic foaming materials effectively, in addition it can also reduce the noise pollution caused by traffic significantly and the wide use of it can improve the urban living environment effectively.

Description

1. Technical Field [0001] The invention relates to a structure of an external thermal insulation composite layer of a building's external wall, and also relates to an external wall external thermal insulation system using the external thermal insulation composite layer of the external wall. 2. Background technology [0002] Engineering experience at home and abroad has proved that the external wall thermal insulation technology system has obvious advantages in building energy saving and indoor environment comfort.
