Description

Technical Field

[0002] Thermal insulation composite exterior wall panels are a new type of wall material that integrates structure, insulation and decoration. They are widely used in modern buildings, especially in the field of energy-saving buildings. Thermal insulation composite exterior wall panels generally include structural layer, insulation layer and finishing layer. The structural layer usually uses reinforced concrete, lightweight concrete, gypsum board or cement fiber board as the substrate to provide the necessary structural strength and support for the entire wall structure. The insulation layer is generally made of high-efficiency insulation materials such as polystyrene foam board, extruded polystyrene foam board, rock wool, glass wool or polyurethane foam to reduce heat transfer and improve the thermal insulation performance of the building. The insulation layer is attached to the surface of the structural layer through anchors and bonding mortar. The finishing layer protects the insulation layer and decorates the entire wall panel. Since the thermal insulation composite exterior wall panel is a prefabricated panel, it only needs to be assembled on site, which improves the construction efficiency. And because of its excellent thermal insulation performance, it reduces the energy consumption of the building, which is conducive to energy conservation and emission reduction.

[0003] However, the existing thermal insulation composite exterior wall panels are obtained by adding an insulation layer on the basis of the structural layer. The insulation layer is located on the outside, and the protective effect of the finishing layer on the insulation layer is relatively poor, which is easy to cause damage to the insulation layer and affect the insulation effect.
