External wall heat preservation structure for decoration

LIN YONGHUI / WANG PINGPING

The invention relates to the technical field of heat preservation walls, and discloses an external wall heat preservation structure for decoration. The structure comprises an external wall. A breathable layer is arranged on the external wall. Heat preservation layers are laid on the breathable layer. A fireproof isolation layer is laid between the heat preservation layers. The heat preservation layers and the fireproof isolation layer are coated with an interface agent layer. The interface agent layer is coated with an anti-cracking rubber cement layer. A galvanized steel wire net is laid on the anti-cracking rubber cement layer. The galvanized steel wire net is coated with a cement layer. According to the external wall heat preservation structure for decoration, the XPS heat preservationplates are adopted as the heat preservation layers, the structure has the advantages of being high in heat resistance, low in linearity and low in expansion ratio. The percentage of close area of thestructure can reach % or more, a vacuum layer is formed, air flow heat dissipation is avoided, it is ensured that the heat preservation performance is lasting and stable, no decomposition or mildewinghappens, no toxic substance volatilizes, and the heat preservation layers laid on the XPS heat preservation plates are isolated by the fireproof isolation layer.

本发明涉及保温墙体技术领域，且公开了一种装饰用外墙保温结构，包括外墙，所述外墙上设置有透气层，且透气层上铺设有保温层；所述保温层之间铺设有防火隔离层；所述保温层和防火隔离层上涂覆有界面剂层；所述界面剂层上涂覆有抗裂胶浆层；所述抗裂胶浆层上铺设有镀锌钢丝网；所述镀锌钢丝网上涂覆有胶浆层。该装饰用外墙保温结构，采用XPS保温板作为保温层，具有高热阻、低线性、膨胀比低的特点，其结构的闭孔率达到了％以上，形成真空层，避免空气流动散热，确保其保温性能的持久和稳定，且不会发生分解或霉变，没有有毒物质的挥发，而在XPS保温板铺设的保温层中利用防火隔离层将保温层分隔。
