Abstract: Cardanol modified phenolic formaldehyde resin was synthesized by using phenol 100 phr, cardanol 40 phr and adding an additive agent. The suitable synthetic conditions were as follows: molar ratio of phenol to formaldehyde was 1:0.85, phenol 100 phr, cardanol, additive agent and HCl were 40 phr, 7 phr and 1.3-1.9 phr respectively, pH value 1.5-2.0, reaction time 3.5-4h, discharge temperature 180-190℃, and dark red solid resin was obtained, reaction yield was 66.9%. The properties of the resin were softening point 84-92℃, mobility length 2.5-4.9cm, gelling rate 60-90s, viscosity 14-16 mPa·s, 25℃.

Key words: cardanol, additive agent, phenol-formaldehyde resin
