Abstract
The invention discloses a novel process for modifying wood through environment-friendly polyester chemical crosslinking, belongs to the technical field of wood chemical modification, and provides a process for modifying wood through biodegradable elastomer polyester. Organic acid and dihydric alcohol infiltrate wood in a molten state according to the molar ratio of 0.5: 1-1: 3, the two monomers are subjected to a cross-linking reaction under proper conditions, and meanwhile substances in a system and wood hydroxyl are subjected to a chemical reaction and fill wood cell cavities and cell walls. The process method of the environment-friendly polyester chemical crosslinking modified wood comprises the following steps: (1) melting organic acid and dihydric alcohol; (2) synthesis of biodegradable polyester and wood impregnation; and (3) drying the wood. The process method is simple and efficient, and the prepared wood has durability and stability and has extremely high application value.
