摘要： 以长碳链酚类化合物腰果酚为原料,研究了生物基增塑剂腰果酚基乙酸酯的合成及其增塑性能。结果表明,当增塑剂用量增加到 10%,环氧树脂128/934固化体系拉伸强度和断裂伸长率比空白样分别增加了 39.1% 和 185.8%。与邻苯二甲酸二辛酯(DOP)、对苯二甲酸二辛酯(DOTP)相比,同等比例下,腰果酚基乙酸酯所在固化体系拉伸强度比DOP高 38.1%,比DOTP高 36.6%;断裂伸长率比DOP高 145.9%,比DOTP高 51.6%,体系玻璃化转变温度为 63.3℃,略低于DOP。腰果酚基乙酸酯是一种增塑性能类似于邻苯二甲酸二辛酯增塑剂,有望成为邻苯二甲酸类增塑剂的替代品,具有广阔的发展前景。

Abstract: Bio-plasticizer cardanol acetate was prepared using natural phenolic compounds cardanol as raw material. Its plasticized performance was also studied. When the content of cardanol acetate increased to 10%, the tensile strength and elongation at break of epoxy resin 128/934 system increased to 39.1% and 185.8%, respectively. Compared with dioctyl phthalate(DOP) and dioctyl terephthalate(DOTP), tensile strength and elongation of the cured system with cardanol acetate increased by 38.1%, 36.6% and 145.9%, 51.6%, respectively. The glass transition temperature of epoxy systems was 63.3℃ using cardanol acetic, which is lower than that of DOP. Cardanol acetate gives good plasticized performance which is similar to that of DOP. It has high protential to be used as substitute for DOP in the future.

Key words: cardanol, cardanol acetate, plasticized performance, epoxy resin
