摘    要:采用静态浸泡法得到了漆膜增重-时间曲线,研究了酸溶液在纳米蒙脱土(nano-MMT)改性光固化涂层中的渗透行为.结果表明:浸泡初期,介质在涂层中的传输行为符合Fick扩散定律,之后涂层吸收量达到饱和,由计算公式可求得渗透介质在涂层中的扩散系数;添加nano-MMT、增加WEA:WAD的比例和提高交联密度可以减小渗透介质的扩散系数,提高涂层的抗介质渗透性能.

关 键 词:紫外光固化涂料  纳米复合涂料  介质传输

Abstract:Permeation behavior of UV-cured coating modified by nano-montmorillonite(nano-MMT) was investigated by using static immersion method.The relationships between the medium permeation and the addition of the amount of nano-MMT,the weight ratio of epoxy acrylate(EA) to a home-made photosensitive reactive diluent(AD),curing degree of the UV-cured coating,and the sorts of acid medium were discussed.The result showed that permeation behavior of medium followed Fick diffusion law in the early stage,later water abso...
Keywords:UV-curable coatings  nano-composite  medium permeation  acid
