摘要
通过改变聚酰亚胺的用量,制备出系列聚氨酯-酰亚胺复合材料。采用FT-IR(傅里叶转换红外光谱)、DSC(差示扫描量热仪)、TG(热重分析)、拉伸测试和化学耐性测试等方法对聚氨酯-酰亚胺复合材料的胶膜结构和性能进行测试表征。探讨聚酰亚胺含量对聚氨酯-酰亚胺复合材料性能的影响。结果表明:随着聚酰亚胺用量的增加,聚氨酯-酰亚胺胶膜的拉伸强度呈现先增加后减小的趋势,断裂伸长率降低;胶膜的耐热性、耐水性、耐碱性和耐酸性都有所增强。
A series of polyurethane-imide（ PUI ）composite materials were synthesized by adding different amount of polyimide. The FT-IR, DSC, TG, tensile and chemical resistant tests were conducted to characterize the glue film structure and properties, and to analyze the influence of the amount of polyimide on the properties of polyurethaneimide composite materials. Results showed that, with the increasing amount of polyimide, the tensile strength first increased and then decreased, and the breaking elongation decreased, the resistance of PUI glue film to heat, water, alkali and acid was strengthened.
