| 摘 要： | 采用双酚F型环氧树脂NPEF-170与聚乙二醇400二缩水甘油醚为原料制备了双官能度的环碳酸酯,再与聚醚胺T403反应合成了非异氰酸酯聚氨酯（NIPU）,并且利用FT-IR时产物的结构进行了表征。同时探讨了反应条件对环氧树脂转化率的影响。研究了不同质量比的原料对非异氰酸酯聚氨酯力学性能的影响,研究表明,当原料的质量比为3：7时所制备的NIPU材料的力学性能最好。最大拉伸强度为7．58MPa,扯断伸长率为347％。

| Abstract: | Bifunctional cyclic carbonate was synthesized by bisphenol F epoxy resin NPEF-170 and diglycidyl ether of polyethylene glycol 400. Then non-isoeyanate polyurethane was prepared by aliphatic primary diamines T403 and cyclic carbonate. And the structure of cyclic carbonate and NIPU was characterized by FT-IR analysis. At the same time, the factors affecting the conversion rate of epoxy resin were explored. The paper also studied the effect of different mass ratio of epoxy resins for the non-isocyanate polyurethane in mechanical properties. The study have shown that NIPU could achieve superior mechanical when the mass ratio of the raw material was 7： 3. The maximum tensile strength could reach 7.58 MPa, the elon- gation at failure was 347%. |
