| Abstract: | The technique for preparing phenol formaldehyde resin from phenolated wood (PWF) and its characters were studied and analyzed.
Poplar (Populus spp) wood meal was liquefied by phenol in the presence of sulfuric acid as a catalyst. After the liquefied products were cooled,
alkaline catalyst and formaldehyde were added. The mixture was kept at (60±2)°C for 1h and then was heated to (85±2)°C for
1h. The influence of molar ratio of formaldehyde to phenol (F/P) was investigated. The results showed when the molar ratio
of formaldehyde to phenol was over 1.8, the PWF adhesives had high bond quality, bond durability and extremely low aldehydes
emissions.
Foundation item: The research was supported by Sino-Japanese Technical Cooperation Project (2-1-b) and the key technologies R & D Program
for the 10th Five-Year Plan (325-11).
