摘要
介绍了以蓖麻油酸改性环氧酯为含羟基树脂,以二丁胺改性1,6-己二醇二缩水甘油醚为反应性稀释剂,配合聚苯胺/凹凸棒纳米复合材料、磷钛粉、吸水剂等组成A组分,采用含—NCO基的聚氨酯预聚体为B组分,将A组分和B组分按规定比例混合均匀后涂布在金属表面即形成一种无溶剂、不含重金属的新型环境友好金属防锈涂料。
A two-component anti-rust coatings formula is designed in this paper. The component A includes ricinoleic acid modified epoxy ester as hydroxyl resin, n-dibutylamine modified 1,6-hexylene glycol two glycidyl ether as reactive thinner, Polyaniline/Attapulgite nanocomposites, titanium phosphide powder and water absorbent. The component B includes --NCO polyurethane prepolymer. The two components are mixed at some proportion and applied on the metal surface to serve as non- solvent non-heavy metal environmental friendly metal anti-rust coatings.
