The present application discloses a method for applying polymeric adhesive as adhesive agent to bond wood article or garnish, the polymeric adhesive comprises starch and polymeric macromolecule or adhesive containing the polymeric macromolecule, the method includes: modifying the starch and polymeric macromolecule, graft polymerizing the modified starch and polymeric macromolecule in a container at 20-100 to producing the polymeric adhesive. The method may bond all kinds of wood articles together, such as wood furniture, woof furniture, cabinet, plywood, lumbercore plywood, density board, flake board, etc., it also can be used as inner wall coating, lacquer putty, for bonding the inner wall tile, wallpaper, wall covering, garnish paster, carpet, leather. When dipped in the water for 48 hours or boiled in the water at 63 for 3 hours, the bonded article does not crack. The shear strength dry strength of the standard sample may be up to 5-14 mPa, the green strength can reach to 2-7 mPa. |
