腰果酚基缩水甘油醚的制备及其性能研究
|
摘要
以腰果酚、环氧氯丙烷为主要原料,制备腰果酚基缩水甘油醚(CGE),并研究CGE/双酚A型环氧树脂(DGEBA)固化物的性能。研究表明,在CGE用量达15%时,环氧树脂固化物的机械性能达到最大值。与纯DGEBA的性能相比,复合材料的拉伸强度、弯曲强度、冲击强度分别提高了35.4%,43.3%和109.5%。随着CGE含量的增加,材料的玻璃化转变温度降低。固化微观相分离和断面出现"海岛"结构是腰果酚基缩水甘油醚的增韧机理。
Reports on the synthesis of cardanol glycidyl ether( CGE) and the hybrid composite of CGE and diglycidyl ether of bisphenol-A( DGEBA). Studied was shown that,the mechanical performance of the CGE / DGEBA blends had maximum with the increase of CGE content. The tensile strength,flexural strength and impact strength of the cured system with 15% CGE can be enhanced respectively about35. 4%,43. 3% and 109. 5%. The toughness mechanism is the micro-phase separation during curing and sea-island microstructure appearing on the fractured surface.
