摘要
用苯酚、甲醛和已二胺制备苯酚缩甲醛己二胺(PRH)聚合物,并对其固化环氧树脂(ER)的过程以及产物PRH/ER的性能等进行研究.结果表明,适量的己二胺与酚醛树脂(PR)制得的PRH聚合物,其固化ER的产物涂膜理化性能、贮存稳定性较佳,尤其具有优异的耐酸、碱性能.IR、GPC结果表明,PR中羟甲基与己二胺中的胺基发生缩合反应,并生成PRH聚合物;PRH固化ER的过程中环氧基与氨基上的活泼氢发生开环加成反应,使PRH/ER发生交联聚合成膜,该膜具有优良的抗化学介质性能.
The paper is concerning the preparation of the Phenol-aldehyde-hexanediamine co-polymer （PRH） ,with the study of its solidifying process to epoxy resin （ER） and the properties of its product PRH-ER. The results show that the PCH-ER,obtained by the polycondensation between 1,6-hexanediamine and Phenol-aldehyde polymer（PR）,has better physical and chemical properties in film and better stability,especially excellent property of resisting the acid and alkali. The results of infrared spectrum and GPC indicate that hydroxymethy in PRH may interact with the aminonaphthalene in multi-amine, and could be polymerizated to PRH. Under the addition of epoxy group in ER and the active hydrogen in aminonaphthalene in PRH, the PRH-ER has been crosslinked and polymerizated in the solidifying process,and has better chemical properties in film.
