Description

[0001] technical field

[0002] The invention relates to sandwich panels in the technical field of shelters, in particular to a honeycomb sandwich panel and a manufacturing method thereof. Background technique

[0003] The sandwich panel is composed of a sandwich core and two inner and outer covering boards, and the two covering boards are respectively bonded and hot-pressed with the two sides of the sandwich core through an adhesive. The sandwich core is a honeycomb core or a foam core, the honeycomb core is a paper honeycomb core, an aluminum honeycomb core or a plastic honeycomb core, and the foam core is polyurethane (PU), polystyrene extruded board (XPS) or polystyrene foam (EPS) ) and other foam materials, the sandwich core is a honeycomb core called a honeycomb sandwich panel, and the sandwich core is a foam core called a foam sandwich panel.

[0004] Traditional shelters are generally assembled from polyurethane sandwich panels through connectors. The wall panels ar...
