Problems solved by technology

The embedded foam honeycomb sandwich panel has both the excellent performance of the foam sandwich panel and the honeycomb composite panel. The foam (4) has good thermal insulation performance, and it is embedded in the honeycomb (1) to prevent the air in the core cell of the honeycomb (1). Convection, thereby improving the thermal insulation performance of the honeycomb panel; but the thermal insulation performance of the honeycomb sandwich panel after the cabin can not meet the requirements of the military standard I (thermal conductivity ≤ 1.5W / (m 2 K)); and the invention does not provide a manufacturing method for embedded foam honeycomb sandwich panels

Abstract

A honeycomb sandwich panel sequentially comprises an outer covering, a honeycomb core and an inner covering, grids of the honeycomb core are filled with rigid polyurethane foam, and the thickness of the rigid polyurethane foam is above 2mm. The invention also provides a making method of the honeycomb sandwich panel. The honeycomb sandwich panel has a good heat insulation performance and a high strength; and the heat insulation grade of a shelter body made by adopting the honeycomb sandwich panel reaches military standard I grade requirement. The method has the advantages of simple making technology and low cost.

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...
