研制了一种低粘度、45°C工作时间长的新型耐辐射环氧树脂体系。该体系由环氧三缩水甘油基对氨基苯酚（TGPAP）、环氧异亚丙基双酚双[（2-缩水甘油氧基-3-正丁氧基）-1-丙醚]（IPBE）和二乙基甲苯二胺（DETD）组成。采用真空加压浸渍法制备了不同配比的TGPAP/IPBE/DETD环氧树脂基无硼玻璃纤维复合材料。TGPAP/IPBE的比例影响浸渍时的工作时间和粘度。在室温下测量了1 MGy的60 Co γ射线辐照前后复合材料在300 K和77 K下的力学性能。γ射线辐照对复合材料的性能几乎没有影响。
A new radiation-resistant epoxy resin system was developed that has low viscosity and long working time at 45°C. The system consists of triglycidyl-p-aminophenol (TGPAP) epoxide, isopropylidenebisphenol bis[(2-glycidyloxy-3-n-butoxy)-1-propylether] (IPBE) epoxide and diethyl toluene diamine (DETD). Boron-free glass fiber composites of epoxy resin with different ratio of TGPAP/IPBE/DETD were prepared by vacuum press impregnation. The ratio of TGPAP/IPBE affected the working time and the viscosity at the impregnation. The mechanical properties of the composites at 300K and at 77K were measured before and after60Co γ-ray irradiation of 1MGy at ambient temperature. The γ-ray radiation scarcely affected the properties of the composites.
