天津市城市建设学院材料科学与工程系采用端羧基液体丁腈橡胶(CTBN)作为环氧树脂的增韧剂,研制成功双组分室温固化CTBN改性环氧树脂结构胶。甲组分是由E-51和E-44混合型环氧树脂与CTBN配比为8∶1,在200℃反应2.5 h,加入氧化镁、氧化铝(用量为环氧树脂和增韧剂总量的1%)搅拌混合
Tianjin Institute of Urban Construction, Department of Materials Science and Engineering Using terminal carboxyl liquid nitrile rubber (CTBN) as a toughening agent for epoxy resin, the successful development of two-component room temperature curing CTBN modified epoxy structural adhesive. A component is composed of E-51 and E-44 mixed epoxy resin and CTBN ratio of 8: 1, at 200 ℃ for 2.5 h, adding magnesium oxide, aluminum oxide (epoxy resin and the total amount of toughening agent 1% of the amount) with stirring
