摘要
为了解决环氧树脂固化导致严重脆弱,低韧性和恶劣的内冲击性缺点,在特定范围内限制适用的问题,本文通过整理近年来环氧树脂增韧的相关文献,研究了热塑性树脂的改性方法和改性后界面情况的进展,对聚砜、聚醚砜、聚醚醚酮、聚酰亚胺等热塑性树脂增韧环氧树脂研究现状进行了分析.研究发现:热塑性树脂增韧环氧树脂的共混体系从均相状态到高交联结构的固定相形态,这种转变极大程度提高了材料的性能.
Abstract
Epoxy resin becomes severely fragile with low toughness and poor internal impact after curing,limiting its application to a specific range.To address these problems,the modification methods for thermoplastic resin and the research progress of resin interface after modification were investigated by examining relevant studies on epoxy resin toughening.The research status of epoxy resin toughened using thermoplastic resins,such as polysulfone,poly-ethersulfone,polyether ether ketone,and polyimide,was analyzed.It was revealed that blends of epoxy resin toughened using thermoplastic resin changed from a homogeneous state to a fixed phase morphology with a high crosslinking structure,which greatly improved the properties of the materials.
