摘要： 用100份苯酚(以质量计),加入40份腰果酚,并加入一种助剂合成腰果酚改性酚醛树脂。经过多次试验得到合适的工艺为:酚与甲醛物质的量之比为1:0.85,苯酚100份,腰果酚40份,助剂7份,盐酸1.3~1.9份,pH值为1.5~2.0,反应时间3.5~4 h,出料温度180~190℃,得到深红色固体树脂,得率 66.9%。树脂性能:软化点84~92℃,流淌度2.5~4.9cm,聚合速度60~90s,黏度14~16 mPa·s,25℃。

关键词: 腰果酚, 助剂, 酚醛树脂

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
