Abstract
Finishing of decorative and/or overlay papers impregnated with aminoplast resin which are used for coating composite wood panels and form an abrasion-resistant, easy clean and hydrophobic surface, wherein after resin impregnation, the impregnated papers are coated in a second application step with a sol-gel preparation containing dissolved metal alkoxides and fullerene-like nanostructures and nanotubes made of metal disulfides of the metals molybdenum and/or tungsten and, after drying and final condensation, the surfaces are formed in a hydraulic heating press.
Claims8
A method comprising:
- providing decorative and/or overlay papers,
- impregnating the decorative and/or overlay papers with aminoplast resin to form impregnated papers,
- after the impregnation, coating the impregnated papers with a sol-gel preparation comprising:
- dissolved metal alkoxides,
- fullerene-like nanostructures made of metal disulfides of molybdenum and/or tungsten, and
- fullerene-like nanotubes made of metal disulfides of molybdenum and/or tungsten
- such that coated papers are formed,
- drying the coated papers to form dried papers, and
- pressing the dried papers in a hydraulic heating press such that the dried papers are condensed and such that an abrasion-resistant, hydrophobic surface is formed on the dried papers so that finished papers are formed.
