Treating wood, e.g. for restoring and/or conserving old wood or reducing drying times, comprises polycondensation of drying oils or diglycidyl and diamine monomers in situ

摘要

Treating wood by in-situ polymerization comprises impregnating wood with a drying oil or a combination of diglycidyl and diamine monomers and exposing the wood to electromagnetic radiation with a wavelength of 0.001-1 m for 5-40 seconds at a power of 300-1000 W. An independent claim is also included for a piece of wood-resin composite material produced as above.
