摘要
系统地介绍了环氧树脂的增韧改性方法,对橡胶增韧、热塑性树脂增韧、互穿网络结构增韧以及树枝形分子增韧环氧树脂等的增韧机理进行了分析,重点介绍了"柔性链段"增韧机理和方法。
This paper systemically introduced the toughening methods for modifying epoxy resins presently, including rubber toughening, thermoplastic resin toughening, IPN toughening, ＂ flexible chain＂ toughening and arborization molecule toughening epoxy resins. The toughening micromechanism for the marked increase of toughness in the presence of flexible side chain was then identified.
