- 两种桐油多元醇及其水性聚氨酯合成与热重分析
- <正>本文以两种自制桐油多元醇、聚四氢呋喃醚二醇、4,4''''-二环己基甲烷二异氰酸酯(HMDI)、二羟甲基丙酸(DMPA)和乙二胺(EDA)为原料,合成了含共轭双键的桐油基水性聚氨酯。采用热重分析法在氮气气氛下研究了...

- 2014年
- 利用TG-DTG技术在不同升温速率下研究了本实验室所制备的两种桐油多元醇的热分解行为,并通过Kissinger法确定了热分解动力学参数.结果表明:在氮气气氛下随着升温速率的增加,桐油多元醇的热分解温度提高;醇解桐油多元醇的热失重过程分为两个阶段,胺解桐油多元醇的热失重过程则分为3个阶段;通过不同实验数据拟合得到反应活化能(E)和频率因子(A),为桐油多元醇在聚氨酯等方面的应用提供了相关理论依据.
