| 摘 要： | 采用聚氧化丙烯三醇(N330)、2,4-甲苯二异氰酸酯(TDI)、有机纳米蒙脱土等为原材料,分别制备了相应的聚氨酯预聚体和有机蒙脱土纳米插层聚氨酯预聚体,并以此对环氧树脂E44进行化学共聚改性,系统研究和测试了改性环氧树脂复合材料的力学性能等。研究表明,有机蒙脱土纳米插层聚氨酯比相应的聚氨酯预聚体改性环氧具有更明显的技术提高效果,能更大幅度提高环氧复合材料的韧性等,作为新型环氧类建筑结构胶粘剂,具有更优的性能和应用价值。

| Abstract: | Polyoxypropyleneglycol (N330), toluene diisocyanate (TDI) and organic montmorillonite (MMT) were used as raw materials to prepare corresponding polyur ethane and polyurethane/montmorillonite nanocomposites respectively which were u sed to toughen epoxy resin, E44. Mechanical properties of modified epoxy resin w ere systematically studied and tested. Testing results showed that compared with the other two polyurethane prepolymers, polyurethane/montmorillonite nanocompos ite was even better improved on its toughness and as a new epoxy architectural s tructural adhesive, could be more valuable in performance and application. |
