Embodiment Construction

[0017] An interior panel, its core material, and a method of manufacturing the core material according to one embodiment of the present invention will be described.

[0018] exist figure 1 The middle shows the core material structure of this embodiment. Such as figure 1 As shown, the sheet material 2 is adhesively fixed on both surfaces (the front surface and the back surface) of the honeycomb structure 1 to form the core material 7 . As the adhesive for bonding the sheet 2 to both upper surfaces of the honeycomb structure 1, a non-aqueous adhesive can be used. Since the non-aqueous adhesive will not emit water when hardened, after the sheet material 2 is fixed on both surfaces of the honeycomb structure 1, the water will not be sealed inside the honeycomb structure 1 .

[0019] In this embodiment, the structure and material of the sheet 2 are not particularly limited. For example, by coating the non-aqueous adhesive on the entire surface of the sheet material 2, the non-a...

Abstract

The invention provides an add-in board for door, space wall, inner wall, side sheet of cabinet and core material for add-in board. A sheet is arranged to the inside and outside surface of a honeycomb body, the sheet is cemented on the honeycomb body with a non-aqueous adhesive, and the non-aqueous adhesive can be applied on the nearly all the surface of the back of the sheet, for example using heat-fused adhesive as non-aqueous adhesive. The non-aqueous adhesive layer forms a moisture barrier.

Description

technical field [0001] The present invention relates to an interior panel capable of effectively suppressing the occurrence of dew condensation, a core material with high moisture resistance, and a method for manufacturing the core material. Background technique [0002] As described in Japanese Patent Application Laid-Open No. 10-711, conventionally, an interior panel using a honeycomb structure as a core material is well known. In such a core material, moisture-impermeable sheets are laminated on both surfaces of the honeycomb structure. An interior panel is produced by respectively fixing a wooden decorative panel on both faces of the core material. Since the use of this interior panel suppresses the absorption and emission of moisture from the backside of the wood decorative panel, occurrence of warping can be prevented. [0003] In the above-mentioned conventional interior panels and their core materials, general vinyl acetate resin adhesives are used as woodworking a...
