摘要
通过使用聚合诱导相分离技术,研制成功以少量的热塑性塑料为连续相的耐高温高强度环氧树脂复合胶粘剂,分别在聚醚酰亚胺改性环氧树脂的体系中得到了分散相、双连续相以及反转相结构,使得环氧树脂胶粘剂的耐热性能得到大幅度的提高。为了精确控制改性体系的相形态,对聚醚酰亚胺的用量、分子质量等对相形态的影响进行了深入研究,得到了控制相形态的关键因素。
A high temperature resistant, high performance epoxy adhesive was prepared by the modification of epoxy resin with thermoplastics via reaction-induced phase separation. Three kinds of morphologies, particle, bicontinuous, and phase inversion, were observed in the modification systems, and continuous thermoplastic-rich phase structure increased the high temperature properties of adhesive apparently. The morphology and properties are related to the fraction and molecular weight of polyetherimide.
