摘要
用一种新型环氧树脂固化剂THEIC改性桐油酸酐 (TTOA) ,确定了桐油酸酐与THEIC的物质的量之比为 1∶1 ,反应温度控制在 1 50℃ ,体系酸值 (以KOH计 )不大于 90mg/g,反应 4h。利用IR光谱确认了产物的化学结构。热失重分析结果表明 ,该固化剂可以提高环氧树脂耐热性。
A new curing agent (TTOA) was synthesized using tri(2-hydroxyethyl) isocyanurate and eleostearic acid anhydride.The reaction time was 4 h,temperature was 150 ℃.The structure of TTOA was investigated by IR spectrum.The results showed that the curing agent improved the heat resistance of epoxy resin.
