Melamine Decorative Board

摘要

Provided is a melamine decorative board having a milky-white core layer and less warpage. When the melamine decorative board is bonded onto a base plate such as a plywood, a particle board, and a steel board, a color tone of the base plate does not appear through to a decorative layer. Stacked and thermal-pressure-formed are: a resin-impregnated patterned paper as the decorative layer; multiple sheets of a resin-impregnated core paper, as the core layer, produced by impregnating a whitish fibrous base material with a resin liquid including: a condensate of melamine and formaldehyde, and a divalent polyalkylene glycol or a derivative thereof, or a tri- or more valent polyalkylene glycol polyvalent ether, and drying the whitish fibrous base material; and a resin-impregnated backside paper, as a backside layer, produced by impregnating a fibrous base material with a condensate of melamine and formaldehyde and drying the fibrous base material.

1. A method for producing a melamine decorative board comprising:
providing a decorative layer comprising a resin-impregnated patterned paper; impregnating a whitish fibrous base material with a resin liquid and to form a plurality of sheets of resin-impregnated core paper, said resin liquid comprising a condensate of melamine and formaldehyde; and a divalent polyalkylene glycol or a derivative thereof, or a tri- or more valent polyalkylene glycol polyvalent ether; drying the plurality of sheets of resin-impregnated core paper to form a core layer; impregnating a fibrous base material with a condensate of melamine and formaldehyde, wherein an ash content of the fibrous base material is 2-10% by weight; drying said impregnated fibrous base material to form a backside layer; stacking said decorative layer, said core layer, and said backside layer such that said core layer is disposed between said decorative layer and said backside layer; and applying heat and pressure to said stacked decorative layer, core layer, and backside layer to form said melamine decorative board.
