| Abstract: | An environmental friendly modified urea-formaldehyde resin could be produced through the copolymerization reaction of urea-formaldehyde resin with keratin.The results showed that the optimum molar ratio was 1.31.Equal to 5% urea-formaldehyde resin of keratin was added after the third feeding of urea.The bonding strength of plywood which was made of modified urea-formaldehyde resin met the standard of GB/T9846—2004Ⅱ.The formaldehyde emission accorded with the EI grade of national standard. |

| Keywords: | keratin urea-formaldehyde resin formaldehyde emission bonding strength |
