PRODUCTION AND APPLICATION OF ENVIRONMENT-FRIENDLY BIOPOLYMERS FOR THE PROTECTION OF THE ENVIRONMENT FROM TOXIC FORMALDEHYDE OF WOOD-PRODUCT ADHESIVE


THE INVENTION PROVIDES A NEW ADHESIVE SYSTEM OF WOOD PRODUCTS MADE FROM INCORPORATING BIOPOLYMERS WITH AN AMINO RESIN (UREA FORMALDEHYDE). THE BIOPOLYMERS HAVE IMPROVED REDUCTION OF FREE FORMALDEHYDE OF ADHESIVE SYSTEM. THE ENVIRONMENTAL PERFORMANCE OF THE PREPARED LIGNOCELLULOSIC COMPOSITES WERE EVALUATED TOWARDS THE EFFECT OF INVESTIGATED BIOPOLYMERS ON THE PERCENTAGE OF FREE FORMALDEHYDE AND THE ADHESION PROPERTIES (MECHANICAL AND PHYSICAL PROPERTIES) OF THE PRODUCED COMPOSITE, IN COMPARISON TO THAT PREPARED FROM UN-MODIFIED UREA-FORMALDEHYDE IN PRESENCE OR ABSENCE OF HARDENER. THE OBJECTIVE OF THIS PATENT ALSO FOCUSED ON UPGRADING OF AGRICULTURAL WASTES (E.G., SUGAR-CANE BAGASSE) IN PRODUCTION OF HIGH PERFORMANCE LIGNOCELLULOSIC COMPOSITES (ARTIFICIAL WOOD) FULFILL THE REQUIREMENTS OF GRADE H- 3 IN PARTICLE-BOARD STANDARDS (ANSI).
