可降解松节油基高分子材料的制备及性能研究

Preparation and Performance Study of Degradable Turpentine-based Polymer Materials

以环氧大豆油(ESO)、N,N’-(二呋喃基)-1,8-对䓝烷二胺(FMDA)、6-马来酰亚胺己酸(MA)和己二酸为原料,合成了一种含有酯键和D-A键的生物基材料(FMDA-ESO)。通过傅里叶变换红外光谱(FT-IR)、差示扫描量热(DSC)、热重(TG)、万能试验测试机等测试方法对材料进行表征及测试。实验结果表明:酯键及D-A键的存在使FMDA-ESO材料形成了交联结构,FMDA的刚性结构可提高所得材料的力学性能。随着FMDA-ESO固化配方中FMDA含量增加,材料的热稳定性增加。在乙醇胺的作用下,可实现材料FMDA-ESO快速降解,可在135℃,30 min下降解为数均相对分子质量为2691的低聚物。

A bio-based polymer material FMDA-ESO containing ester and D-A bonds was synthesized from epoxidized soybean oil(ESO),N,N′-(difuranyl)-1,8-p-menthane diamine(FMDA),maleimidic caproic acid and adipic acid.The materials were characterized and tested by Fourier transform infrared spectroscopy(FT-IR),differential scanning calorimetry(DSC),thermogravimetric analysis(TG)and universal test tester.The results showed that the cross-linked structure was formed in FMDA-ESO with the presence of ester and D-A bonds,and the rigid structure of FMDA could improve the mechanical properties of the obtained materials.With the amount increasement of FMDA in the FMDA-ESO cured formulation,the thermal stability of the material increased.Rapid degradation of FMDA-ESO could be achieved in the presence of ethanolamine,which could be degraded to oligomers with a number-average molecular weight of 2691 at 135℃for 30 min.
