For this purpose, tensile and viscometry tests, dynamic mechanical thermal analysis (DMTA), and differential scanning calorimetry (DSC) were carried out under dynamic conditions. The results showed that adding NS and PEG enhances the maximum cure temperature as well as the heat of cure reaction ( ΔgydF4y2Ba HgydF4y2Ba )，而在EP-PEG和EP-PEG- ns中则降低。采用Kissinger、Ozawa和KSA方法计算了EP-PEG-NS的固化动力学参数，并进行了比较。的gydF4y2Ba EgydF4y2Ba 一个gydF4y2Ba 结果表明，用Kissinger法计算的结果(96.82 kJ/mol)低于Ozawa法(98.69 kJ/mol)。同时，根据KAS方法，表面gydF4y2Ba EgydF4y2Ba 一个gydF4y2Ba 在10-90%的转换范围内近似恒定。加入NS后拉伸强度和模量均有所提高，而加入PEG后拉伸强度略有降低。玻璃化温度(gydF4y2Ba TgydF4y2Ba ggydF4y2Ba )用DMTA计算，DMTA随NS和PEG的加入分别增加和减少。粘度测试结果表明，随着聚乙二醇和NS的加入，粘度增加，防止了固体颗粒的沉积。SN - 1687-9422 UR - https://doi.org/10.1155/2020/7908343 DO - 10.1155/2020/7908343 JF - International Journal of Polymer Science PB - Hindawi KW - ER -gydF4y2Ba
