METHOD FOR TREATING WOOD AND WOOD-BASED MATERIALS, AND WOOD AND WOOD-BASED MATERIALS OBTAINABLE THEREWITH

摘要

The present application relates to a method for treating wood and wood-based materials for enhancing dimensional stability and surface properties and also for preventing cracking and extending durability. More specifically the invention for the treatment of wood and wood-based materials is directed to a method wherein the wood or wood-based material is subjected to a thermal treatment and the wood or wood-based material is at least partly impregnated with a melamine-containing resin. Subsequently the wood or wood-based material thus impregnated is cured with hot steam at not more than 125° C. preferably up to a maximum of 120° C. In a further aspect the present application includes the thermally treated wood or wood-based material, impregnated with melamine resin and cured, that is obtainable from the method of the invention. The present invention lastly provides for the use of melamine-containing resin for impregnating wood and wood-based materials which are or have been thermally modified, for the purpose of increasing the hardness and reducing the dimensional change through thermal modification. The material produced in accordance with the invention can be used as a substitute for teak.
