20170233953 · 2017-08-17 ·

The invention relates to a method for producing a covering layer for elastic laminate comprising a) impregnating a carrier fabric, b) applying a surface coating comprising a crosslinker and a prepolymer that can be crosslinked via reactive end groups, c) crosslinking the crosslinkable prepolymer, and d) drying the elastic laminate covering layer. The papers obtainable in this manner are suitable for producing a laminate that, with the elastic outer face thereof, has a pleasant and appealing feel underfoot and good haptics.

Melamine decorative board

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.

DOOR SKINS AND METHOD OF MAKING

The present disclosure is directed to molded door skins and methods of making. Methods include providing an at least partially consolidated flat wood composite blank. Methods further include positioning a stretchable film on an outer surface of the blank, and pressing the blank and the stretchable film together in a heated press to form the molded door skin. The molded door skin has a first surface and a second surface recessed relative to the first surface by a predetermined distance. A third planar portion extends between first and second planar portions at an angle in a range of 100 degrees and 120 degrees. Cracks or voids formed in the outer surface of the blank during the pressing are filled with the stretchable film such that an outer surface of the molded door skin is substantially or entirely crack and void free.
