【摘要】 采用新系列的DGEBF树脂和一种密度较轻的树脂PPGED按一定的比例混合,并采用DETD作为其固化剂配置低温性能良好的双酚F树脂,并使之与有机蒙脱土复合,制备能在超低温环境使用的低温胶。用XRD、DSC等手段研究了有机蒙脱土在环氧树脂中的插层行为。证明环氧树脂很容易插层到粘土层间,形成稳定的插层混合物。同时采用拉伸试验机测定了纳米复合材料的常温和低温力学性能,与DW-3等低温胶对比发现新研制的胶粘剂有许多优异的性能。更多还原

【Abstract】 In this paper a new epoxy resin system for use in cryogenic composite materials has been studied that is formulation with bisphenol F epoxy、amine curing agent and some auxiliaries with compose by organic montmorillonite( MMT) treated by 16-decyltrimethyl ammonium chloride as inorganic reinforcement. We investigated the microphase of the Eposy/ MMT adhesives was characterized with XRD and DSC. Experiment shows that it has good mechanical properties in low temperature. We think that nanopolymer materials will be good means to improve properties of epoxy resin.更多还原
