| 摘 要： | 用2,6-萘二羧酸(NDCA)对双酚A环氧树脂进行改性,研究了NDCA加入量对双酚A环氧树脂黏度、耐热性和力学性能的影响。结果表明,NDCA能提高环氧树脂的储能模量和玻璃化转变温度,玻璃化转变温度最高达到113℃。NDCA的质量分数小于0.5%时,改性环氧树脂的断裂伸长率随着NDCA加入量的增加逐渐提高,最高达12%。结合傅立叶变换红外光谱测试,提出了NDCA改性双酚A环氧树脂的机理,并对改性环氧树脂性能增强的机理进行了探讨。

Properties of Bisphenol A Epoxy Resin Modiifed by 2,6-Naphthalenedicarboxylic Acid |

| Abstract: | Bisphenol A epoxy resin was modified by 2,6-naphthalenedicarboxylic acid (NDCA). The effects of the content of 2,6–naphthalenedicarboxylic acid on the viscosity,heat resistance and mechanical properties of modified resin were studied. As a result,the storage modulus and glass transition temperature of epoxy resin increase with increasing the content of NDCA, the maximum glass transition temperature of modified resin reaches 113℃. Elongation at break is improved when the content of NDCA is between 0–0.5 wt%. The modification mechanism was proposed based on the Fourier transform infrared spectrometer and the reason of performance improvement was analysed. |
