以天然腰果酚为原料制备了一种高活性腰果酚基环氧稀释剂(CDE),利用所制备的CDE与双酚A型环氧树脂( E-51)共混,再与甲基四氢苯酐进行交联固化反应,通过力学性能测试,研究了稀释剂含量对固化物性能的影响。实验结果表明：CDE对E-51有显著的稀释增韧作用；随着CDE含量的增加,固化树脂的玻璃化转变温度逐渐降低；当CDE的加入量为20%时,固化物的冲击强度及拉伸强度达到最大值,分别为19.17 kJ/m2和56.81 MPa,弯曲强度为108.8 MPa。

A cardanol-based epoxy ( CDE) diluents with high diluting and toughening properties was synthesized from cardanol. The blends of the prepared CDE and bisphenol type epoxy resin (E-51) at different mass ratios were cured with anhydride. The influence of the CDE content on the thermodynamic properties and mechanical properties of the cured epoxy was systematically investigated. The results showed that CDE had high diluting and toughening properties to E-51. The glass transition temperature (Tg) of cured epoxy decreased gradually with the increase of the content of CDE. When the CDE content was 20%,the impact strength and tensile strength of cured epoxy reached the maximum values (19. 17 kJ/m2 and 56. 81 MPa,respectively) while the high bending strength was 108. 8 MPa.
