US 10,105,866 B2 · Method for preparing functional engineered wood

Abstract

The present invention relates to furniture panels, and more particularly, to a method for preparing functional engineered wood. It includes the following steps: make veneer blanks by rotary cutting or splicing, and cut the veneer blanks into desired dimensions to obtain veneers A. Soak the veneers A in a ternary mixed solution of a biomass nanocellulose solubilizer, a fire retardant and an acid dye for toughening, fire retardation and dyeing to obtain veneers B. Add a formaldehyde decomposing powder into a modified MUF adhesive, mix them up, coat the veneers B with the mixture to obtain veneers C. Assemble and cold-press the veneers C to obtain flitches D, and saw the flitches D into desired patterns and dimensions to obtain finished products.
