摘要： 用腰果酚代替部分苯酚改性酚醛树脂,制备可发性甲阶酚醛树脂。并讨论了腰果酚替代量对改性酚醛树脂性能及其泡沫性能的影响,通过红外光谱仪、热重分析仪对树脂结构及热稳定性进行表征,运用万能电子试验机对甲阶酚醛树脂泡沫的力学性能进行了研究。结果表明:当腰果酚替代量为10%时,制得的树脂黏度为4650mPa·s,树脂中游离苯酚含量从6.72%降为5.45%,游离甲醛含量从1.17%降为0.68%,甲阶酚醛树脂泡沫压缩强度达到最大值0.20MPa,但树脂热稳定性及甲阶酚醛树脂泡沫阻燃性有所下降。

Abstract: Phenolic resin was modified by cardanol that replaced part of phenol. The expandable phenolic resol resin was prepared. The influences of the cardanol substitution amount on the properties of phenolic resol resin and phenolic foam were investigated. Using the IR spectra and thermo gravimetric analyzer, the structure and thermal stability of resin were analyzed. The mechanical property was studied by the electronic universal testing machine. The results showed that the resin viscosity was 4 650 mPa·s, free phenolic content decreased from 6.72% to 5.45%, free formaldehyde content decreased from 1.17% to 0.68% and the maximal compressive strength of phenolic foam reached 0.20 MPa when the cardanol substitution amount was 10%. But the thermal stability of phenolic resin and the flame retardant of phenolic foam were reduced.

Key words: cardanol, modification, phenolic resin, phenolic foam
