摘　　要：以聚酯多元醇、甲苯二异氰酸酯和3-巯丙基三甲氧基硅烷为原料合成硅氧烷改性聚氨酯低聚物(TMP),采用傅里叶变换红外光谱仪、热重分析仪、接触角仪和万能拉伸试验机研究了TMP的结构、热稳定性、润湿性和力学性能等。结果表明:TMP具有良好的热稳定性、较强的粘接性,TMP5在阳极氧化铝上的破坏载荷可以达到11 kN。同时,固化后TMP5拥有良好的润湿性,为其与聚氨酯密封胶的粘接提供了有利条件。The siloxane-modified polyurethane oligomer(TMP)was synthesized from polyester polyol,toluene diisocyanate and 3-mercaptopropyltrimethoxysilane.The structure,thermal stability,wettability and mechanical properties of TMP were studied by Fourier transform infrared spectrometer,thermogravimetric analyzer,contact angle meter and universal tensile tester.The results show that TMP has good thermal stability and strong adhesion,and the breaking load of TMP5 on anodic alumina can reach 11 kN.At the same time,the cured TMP5 has good wettability,which provides favorable conditions for its adhesion with polyurethane sealant.
