摘    要:以苯酚和双环戊二烯为原料,通过Friedel-Crafts反应,合成了双环戊二烯酚树脂(DPR)。用环氧氯丙烷对该树脂进行环氧化,还制得了含有双环戊二烯结构的环氧树脂(DER)。系统地考察了合成反应的条件,所得环氧树脂的最大环氧值为0.31~0.35,有机氯含量小于0.02mol/100g。用红外光谱考察了以甲基六氢苯酐(MeHHPA)为固化剂时该树脂在180 ℃时的固化速度,固化3.5 h时, 环氧开环的转化率大于92%。DSC的分析表明DER与双酚A环氧树脂E51混合(质量比为1:1),固化树脂的玻璃化转变温度Tg比E51固化树脂的玻璃化转变温度高15 ℃。

关 键 词:双环戊二烯酚树脂  双环戊二烯环氧树脂  合成  固化

Abstract:Using phenol and dicyclopentadiene (DCPD) as raw materials, DCPD-containing phenolic resin (DPR) was prepared via Friedel-Crafts alkylation and DCPD-containing epoxy resin (DER) was prepared via epoxidation of DPR with epichlorohydrin. Their reaction conditions and mode were optimized. The epoxy value of DER is 0.31~0.35. The content of organic chloride is less 0.02 mol/100g. MeHHPA as curing agent, the curing was carried out and the rate of curing was evaluated by FT-IR. When the curing temperature is 180 ℃, the yield of the opening of epoxy group was more than 92% after 3.5 h. DSC analyses found that the Tg of cured epoxy resin DER+E51(1:1) is higher than that of resin E51.
Keywords:DCPD-containing phenolic resin  DCPD-containing epoxy resin  synthesis  curing
