    摘要:

    以纯度≥99.5%的缩水甘油硝酸酯(GN)为原料, 采用阳离子聚合, 合成了两种分子量3000左右的聚缩水甘油醚硝酸酯(PGN)粘合剂。采用红外(IR)、核磁(NMR)和凝胶渗透色谱(GPC)表征了它们的结构。测试了PGN的主要性能。研究了PGN与常用异氰酸酯[多苯基多亚甲基多异氰酸酯(PAPI)、改性六亚甲基多异氰酸酯(N-100)、甲苯二异氰酸酯(TDI)、二环己基甲烷二异氰酸酯(HMDI)]的固化反应。结果表明, 在催化剂二月桂酸二丁基锡(DBTDL)或三苯基铋(TPB)作用下, PGN可与PAPI、N-100、TDI、HMDI等快速反应固化。固化试样经60 ℃贮存60天, 邵A硬度无明显下降。

    Abstract:

    Two kinds of poly(glycidyl nitrate)(PGN) binders with molecular weight of about 3000 were synthesized via cationic polymerization using glycidyl nitrate(GN) with purity of more than 99.5% as raw material. Their structures were characterized by infrared spectroscopy(IR), nuclear magnetic resonance(NMR) and gel permeation chromatograph(GPC). The main properties of PGN were tested. The curing reaction of PGN with common isocyanates, polyaryl polymethylene isocyanate(PAPI), modified hexamethylene polyisocyanate(N-100), toluene diisocyanate(TDI), dicyclohexyl methane diisocyanate(HMDI) was studied. Results show that the curing reaction of PGN can performed rapidly with PAPI, N-100, TDI and HMDI etc. under the action of catalysts dibutyltin dilaurate(DBTDL) or triphenyl bismuth(TPB), and the cured samples have no obvious decrease in Shore A hardness after storeing at 60 ℃ for 60 days.
