Advance in low molecular weight resin modification of wood
Since applied range of wood from plantation has been limited due to its low density,poor quality and weak protection properties,the treatment of low molecular weight resin is an effective method for improving properties and additional value of wood from plantation.This paper summarizes the research development of resin modification both at home and abroad in recent years.The modification technology,the change of performance of wood before and after modification,and mechanism of modification are reviewed in detail.The distribution and combining with cell wall of resin in wood are illustrated.The development tendency is proposed so as to provide reference for further study on resin modification.
