摘要:以端羟基聚丁二烯(HTPB)液体橡胶、环氧氯丙烷和w=33%的三甲胺水溶液为原料,三氟化硼乙醚络合物为催化剂,采用酸催化法合成大分子聚丁二烯液体橡胶季胺盐(HTPBQAS)。研究了物料物质的量之比、催化剂用量、开环时间、开环温度及闭环时间对HTPB羟基转化率的影响,红外光谱(FT-IR)与核磁共振谱图(1 H-NMR)表明成功地合成了HTPB-QAS,羟基最大转化率为65.7%。采用溶液法和静置法将HTPB-QAS插层钠基蒙脱土,制得聚丁二烯液体橡胶-蒙脱土纳米复合材料(HTPB-OMMT)。X射线衍射(XRD)、小角X射线散射(SAXS)、热重分析(TGA)和透射电子显微镜(TEM)分析结果表明,HTPB-QAS成功插入钠基蒙脱土片层中,并且复合材料热稳定性得到明显提高。
Macromolecule polybutadiene quaternary ammonium sait (HTPB-QAS) was prepared by acid catalytic method using hydroxyl terminated polybutadiene ( HTPB) , epichlorohydrin and 0 = 3 3 % trimethylamine solution as starting materials and three boron fluoride ethyl ether complexes as thecatalyst. The effects of material ratio% catalyst amount, ring-opening time and temperature, and ring-closing time on the conversion rate of hydroxyl group in HTPB were studied. HTPB-QAS was successfullysynthesized with the conversion rate of hydroxyl group of 65. 7% as confirmed by FT-IR and 1H-NMR. By solution method and static method, HTPB-QAS was intercalated into Na-MMT to obtain HTPBand Na- MMT nanocomposites (HTPB-OMMT) . XRD’ SA X S, FT-IR and TEM results showed that HTPB-QAS was successfully inserted into Na-MMT layers, and TG A results showed that the thecomposites was improved obviously.
