摘　　要：本文以甲基异丁基酮对二苯甲胺改性得到脂肪族胺类潜伏性固化剂,并运用红外光谱法对产物的结构进行表征。从固化剂的固化温度、时间、强度等方面考察其固化性能及其与环氧树脂构成单组分体系的储存稳定性。结果表明,二苯甲胺酮亚胺的固化性能较优越,其固化条件为:120℃、2h,拉伸剪切强度为8.9MPa,贮存期3个月以上。A new kind of latent curing agent was obtained by modifying aminodiphenylmethane with methyl isobutyl ketone, and the structure of product was characterized by Fr - IR. We investigated the curing properties and the storage stability of the product. The results showed that the new curing agent has good stability at room temperature and improved curing performance. It can be cured at 120℃ by two hours and the tensile shear strength is 8.9MPa. The storage period can be above three months at room temperature.
