摘要
采用自制的一种既含柔性链段,又含刚性结构单元的端脂肪氨基聚醚(APPEG)作为固化剂,用于环氧树脂的增韧改性,制备了耐环境性能优异的涂膜。研究表明:涂膜的平衡吸水率为2.1%左右,耐盐雾腐蚀可达500?h以上。
The coatings with good environmental resistance are prepared of epoxy resin which is modified toughened by self-made aliphatic amine-terminated polyether curing agent containing both flexible segments and rigid segments, resulting in the film with 2.1% equilibrium water absorption rate and more than 500hours salt-spray corrosion resistance.
