【摘要】 由甲苯二异氰酸酯(TDI)和端羟基聚丁二烯(HTPB)合成了聚丁二烯氨基甲酸酯脲,用单氨基烷氧基硅烷封端,获得了单包装硅烷封端的聚丁二烯氨基甲酸酯脲密封胶,研究了不同封端剂、不同比例扩链剂以及多种填料对密封胶性质和固化速度的影响。更多还原

【Abstract】 A series of polyurethane-urea was synthesized based on toluene-2,4-diisocyanate (TDI), hydroxyl-terminated polybutadiene(HTPB),and then terminated with different silane couple agents. The influences of different coupling agent,different ratio of chain extender and different fillers to mechanical properties and curing rate were studied.更多还原
