Technical Field

[0001] The utility model relates to the technical field of metal surface polyurethane sandwich panels, in particular to a metal surface polyurethane sandwich panel which can be used for construction. Background Art

[0002] Sandwich panels are composed of two layers of formed metal panels and a polymer insulation core that is foamed and cured directly between the panels. They are easy to install, lightweight, and efficient. The filling system also uses a closed-cell molecular structure to prevent condensation of water vapor. Sandwich panels are a common product in current building materials and have excellent flame retardant, sound insulation, and environmental protection properties. Polyurethane sandwich panels are a type of sandwich panel that uses polyurethane as the filling material for the core panel. The material is lightweight and has good thermal insulation properties, and is often used as a wall installation structure for buildings.

[0003] Polyurethane sandwich panels use polyurethane as the inner cavity filler. Although polyurethane has good thermal insulation properties, its own structural support strength is limited. The inner cavity of the sandwich panel is supported only by the polyurethane filler. Although it is supported and protected by the external metal panel, the strength of the middle part of the sandwich panel is still weak and the structural stability is poor. In addition, traditional sandwich panels are mostly fastened with bolts during installation. The bolt holes will destroy the structural sealing of the panel body and the exposed bolts will seriously affect the installation aesthetics of the wall. Therefore, a metal-faced polyurethane sandwich panel that can be used in construction is proposed. Utility Model Content
