摘要:
文章从浆料适用期、胶膜的表面形态、力学性能等方面研究了不同端羟基聚丁二烯(HTPB)-异氰酸酯体系室温固化的效果。试验结果表明，聚氧化丙烯二醇(N220)的加入，延长了浆料适用期，并初步实现了HTPB-异氰酸酯黏结剂体系在规定时间内（约一周）的室温固化。HTPB-佛尔酮二异氰酸酯（IPDI）体系在适用期、力学性能、胶膜表面形态方面明显优于HTPB-二苯基甲烷二异氰酸酯（MDI）体系。但在固化时间方面，HTPBMDI、HTPB-甲苯二异氰酸酯（TDI）体系比HTPB-4，4′-二环己基甲烷二异氰酸酯（HMDI）、HTPB-IPDI体系短。在胶膜的拉伸性能方面，与国外同类研究在高温固化条件下的性能相当。
Abstract:
Effects of room temperature curing of different HTPBisocyanate binder systems were studied from pot life of the slurry, surface morphology and mechanical properties of the casted films. Results show that, with the additional hydroxyterminated polyether (N220), the pot life of the slurry was increased, and the process of the binder system curing at room temperature within a predetermined time (about one week) was achieved. As for the pot life of the slurry, mechanical properties and surface morphology of the film, HTPBIPDI system was obviously superior to HTPBMDI system. However, in terms of curing time, HTPBMDI and HTPBTDI systems were shorter than HTPBHMDI and HTPBIPDI system. At the same time, the tensile properties of the cured films match those of similar studies abroad that were cured at high temperatures.
