| 摘 要： | 采用聚酯多元醇、发泡剂、表面活性剂等混合而成的组合料与异氰酸酯－聚酯多元醇的预聚物，经反应注射成型，制备聚氨酯发泡材料，考察了扩链剂 EG 的添加量对聚氨酯微孔材料结构与性能的影响。研究结果表明，随着 EG的引入，经过水解，材料的力学性能影响最小；聚氨酯软硬段的最高热失重温度均呈现升高趋势，聚氨酯的耐热性有了提高。

| Abstract: | The composite materials mixed with polyesterpolyol , foaming agent, surface active agent etc.and the prepolymer of isocyanate -polyesterpolyol were made into polyurethane foaming materials through reaction injection moulding .The influence of additive amount of chain extender EG on the structure and property of polyurethane cellular material was investigated .The research result shows that with the introduction of EG, the mechanical property of materials has least influence through hydrolysis , that the highest heat temperature of the soft and hard segments of polyurethane tends to increase and that heat endurance of polyurethane increases . |

| Keywords: | chain extender polyurethane tensile strength tear strength highest heat temperature |
