摘要/Abstract

摘要： 采用Materials Studio分子模拟软件对3-硝酸酯甲基-3-甲基氧丁环聚合物（PolyNIMMO）与甲苯二异氰酸酯（TDI）、异佛尔酮二异氰酸酯（IPDI）和六次甲基二异氰酸酯和水的加成物（N-100）3种固化剂形成的混合体系固化行为及弹性模量进行了理论模拟，并与固化胶片力学性能实测数据进行了对比分析，研究了含能黏合剂PolyNIMMO的固化体系。结果表明：TDI、IPDI和N-100 3种固化剂均可与含能黏合剂发生聚氨酯交联反应，形成稳定的固化体系；与PolyNIMMO匹配的固化剂，以N-100为最佳，固化催化剂则以二月桂酸二丁基锡为最佳，最终形成的固化胶片力学性能为最大抗拉强度3.83 MPa，最大延伸率282%.

Abstract: The curing behaviors and elasticity moduli of poly(3-nitatomethyl-3-methyl oxetane) (polyNIMMO) with toluene diisocyanate (TDI), isophorone diisocyanate (IPDI) and addition product of hexamethylene diisocyanate and water (N-100) are theoretically studied by using Materials Studio. The mechanical properties of the cured systems of polyNIMMO with three curing agents are measured. The results show that the polyurethane reactions among polyNIMMO and three curing agents, TDI, IPDI and N-100, can take place, and the hardener of N-100 and the hardening catalyzer of dibutyltin dilaurate (T₁₂) are the best match with polyNIMMO, which tensile strength and extensibility can be improved to 3.83 MPa and 282%, respectively.
