Abstract

The invention provides a production method of a double-layer honeycomb plate, which comprises the following steps: respectively bonding an ultrathin skin on an upper surface and lower surface of a honeycomb core material to obtain a honeycomb unit; coating an upper surface and lower surface of the honeycomb unit with hot melt adhesive respectively, and covering a structure skin on one of the surfaces of the honeycomb unit coated with the hot melt adhesive; stacking and placing the two honeycomb units which are adhered with structural skins up and down, so that the surfaces of the two honeycombunits coated with hot melt adhesive are bonded to obtain a double-layer honeycomb plate. The production method of the double-layer honeycomb plate is characterized in that the hot melt adhesive is used for bonding between the two honeycomb units and between the honeycomb units and the structure skins, the curing molding time is less than 5 minutes, and compared with the curing time of 1 hour to 2hours in a prior honeycomb plate manufacturing process, the forming speed of the production method is faster, and the production efficiency of the double-layer honeycomb plate can be effectively improved.

Description

Technical field [0001] The invention relates to the field of thermal insulation boards, in particular to a production method of a double-layer honeycomb board. Background technique [0002] The traditional honeycomb panel is a three-dimensional sandwich structure, which has the characteristics of light weight and high strength, and can be widely used in aviation, high-speed rail, new energy vehicles and other fields. The traditional honeycomb panel only includes a layer of honeycomb core material, which has poor sound insulation, heat insulation and fire insulation performance. [0003] To solve the problems of traditional honeycomb panels, technicians have developed a double-layer honeycomb panel. The double-layer honeycomb panel includes two layers of honeycomb core materials, a partition is arranged between the two layers of honeycomb core materials, and a layer of panels are arranged on the upper and lower surfaces of the two layers of honeycomb core materials. The existing d...
