A process for improving the dimensional stability and the mechanical properties of wood, in particular hardness, scratch resistance and gloss while substantially maintaining the wood material appearance combined with an easy processability with tools and industrial machines, characterized in that the wood is subjected to the following steps:
1) drying at 60 -80°C from 1 to 12 hours,
2) vacuum application,
3) wood impregnation with polymerizable monomers selected from C 1 -C 8 alkyl (meth)acrylates, styrene/acrylonitrile, vinylacetate, silane monomers having formula (R 1 ZR 2 ) y Si (OR 3 ) x
and polymerization by using organic or inorganic redox catalysts, the polymerization temperature being comprised between -15 and 40°C, or between >40-80°C.
4) recovery of the wood containing the polymer. |
