摘要：以腰果酚为原料,通过合成腰果酚酚醛树脂,进而合成腰果酚酚醛环氧树脂(Epoxy-Ⅰ)和高环氧值的腰果酚酚醛环氧树脂(Epoxy-Ⅱ),探讨了各阶段的反应条件。其中腰果酚酚醛树脂合成的最佳条件为:催化剂乙酸锌用量为腰果酚质量的3%,在90℃下反应3 h;Epoxy-I合成的最佳条件为:苄基三乙基氯化铵(BTEAC)催化剂用量为2%,在90℃下醚化反应4 h;当环氧化剂用量为Epoxy-Ⅰ质量的80%,在70℃反应6 h可制备出高环氧值的Epoxy-Ⅱ。采用傅里叶红外光谱和核磁共振光谱表征了两种目标环氧树脂的化学结构。
Cardanol novolac epoxy resin I （Epoxy-I） and cardanol novolac epoxy resin II （Epoxy-II） with higher epoxy value were synthesized from cardanol novolac resin synthesized from eardanol reacted with formaldehyde. The effects of various reaction factors on these reactions were investigated. The results showed that the optimal reaction conditions for the synthesis of cardanol novolac resin were as follows： 3 % weight ratio of cardanol used as the amount of zinc acetate, the reaction temperature 90 ℃ and the reaction time 3 h. The optimal reaction conditions for the synthesis of Epoxy-I were that the amount of quaternary BTEAC was 2 % weight ratio of eardanol novolac resin, the reaction temperature was 90 ℃ and the reaction time was 4 h. And the epoxy value of Epoxy-II reaches to the highest when the amount of epoxidizing agent is 80% the weight ratio of Epoxy-I, the reaction temperature is 70 ℃ and the reaction time is 6 h. The chemical structure of both novolac epoxy resin were characterized by FT-IR and NMR spectra.
