Description

Technical Field

[0001] The utility model relates to the technical field of sandwich panels, in particular to a novel metal surface hard polyurethane sandwich panel. Background Art

[0002] As we all know, metal-faced rigid polyurethane sandwich panels refer to the upper and lower layers of metal sheets, and the core material is rigid polyurethane. Polyurethane sandwich panels are made of two layers of high-quality color-coated steel plates or other precision-formed metal sheets as the surface material. After roll forming, flame-retardant polyurethane foam liquid is injected in the middle. Under specific process conditions such as high-pressure foaming and curing, it is strongly bonded with the metal panel to form a beautiful, flat, and tough building board. It has the characteristics of fire prevention, heat preservation, waterproof, and sound insulation, bringing high-quality appearance to the building. It is currently the most forward-looking ideal building board for energy-saving, heat preservation, green environmental protection, and artistic architecture in the world.

[0003] However, when the existing metal-faced rigid polyurethane sandwich panels are manufactured, it is necessary to inject flame-retardant polyurethane foam liquid into the interior and then bond them together through high-pressure foaming and curing. However, the existing metal-faced rigid polyurethane sandwich panels have no supporting effect and will reduce the strength of the panels. Utility Model Content
