摘要: 腰果酚醛树脂中含有较活泼的酚羟基,略显酸性,易受碱的腐蚀。先由共缩聚法得到以苯胺改性的腰果酚醛缩聚物,再使之与CuCl2反应,合成含铜 氮配键腰果酚醛缩聚物。用IR、动态粘弹谱(DMTA)、TG和其他手段对产物的结构和理化性能进行表征。结果表明,金属铜离子与苯胺分子中氮原子形成配位键,增大了涂膜内部的交联度,使分子链间形成更大的网状结构。因此,含铜 氮配键腰果酚醛涂膜的物理机械性能、热稳定性、耐化学介质尤其是耐碱性能得到很大的改善。

Abstract: Cardanol aldehyde condensation resin(CF) is susceptible to corrosion by alkali because of its slight acidity of phenolic hydroxyls.CF was modified by aniline, followed by reaction with CuCl2.The final product of the co condensation polymer containing copper nitrogen coordinated bond(CFNCu) has been synthesized and characterized by IR, dynamic mechanical thermogram analysis(DMTA) and other measures.Results show that copper nitrogen coordinated bond increases the cross linking of coating film, leading to the remarkable improvements of physico mechanical properties, thermo stability and resistance against chemical media, especially alkali.
