- Example 6 An aluminum hydroxide-containing paper honeycomb similar to that used in Example 6 was used as a core material as it was.
- honeycomb core material is cut to a size of 600 x 300 (however, the longitudinal direction is the direction of the honeycomb body), and two points are supported at a span of 500 mm. With the surface facing down), the amount of deflection at the center was measured.
- a sandwich panel in which a 0.8 mm strength steel sheet was adhered to both sides of a honeycomb core material with an epoxy adhesive was measured in accordance with JIS K 911.
- the honeycomb core material according to the present invention is excellent in flame retardancy and non-flammability, which cannot be obtained by a conventional organic foam, because the filler in the cell is a composite foam of the above inorganic and organic materials. Moreover, it has flexibility and elasticity which cannot be obtained with conventional inorganic foams.
- the filler does not fall off the honeycomb body, and transport and handling are easy.
- the foam since the foam has flexibility, it can be deformed after manufacturing, so it has a flat surface
- a honeycomb core material that can be easily attached to a material and is suitable for a structure having a curved surface.
- an aqueous mixture containing a phosphoric acid, a curing agent, a foaming agent, and a urethane polymer having an NCO group is foamed and cured substantially simultaneously in the cells of the honeycomb body, and the inorganic foam and the organic foam are mixed with each other.
- the present invention provides a method for producing a honeycomb core material for forming a composite foam from the above.
- the present invention also provides a method for producing a honeycomb core material in which foaming hardness is suppressed before or during filling of the aqueous mixture into the cells of the honeycomb body, and a composite foam is uniformly formed in the cells of the honeycomb body. Is done.
