摘要
通过超声法制备了超细涂料色浆,并将其应用到阴极电泳漆中。考察了超细化前后涂料色浆的平均粒径、Zeta电位的变化,比较分析了超细涂料色浆与普通涂料色浆用于阴极电泳漆时漆液稳定性、漆膜沉积量、颜色深度、外观的区别。实验结果表明:超细涂料色浆的平均粒径仅为196 nm,Zeta电位为30 mV且分布均匀。用超细涂料色浆配制的电泳漆液具有较高的离心稳定性。相比于含普通涂料色浆的阴极电泳漆,含有超细涂料色浆的阴极电泳漆的漆膜的电沉积量稍高,而且更加均匀、平整、细腻。
The ultrafine colour paste, which was used in cathodic electrophoretie paint, was prepared via ul- trasonic method. The average particle size and zeta potential of the ultrafine paint was discussed. The differences of the cathodic electrophoretic paint containing ultratine eolour paste or common eolour paste, in stability of bath, deposition amount, color depth and appearance of film were analysised and compared. The results showed that the average particle size of the ultrafine colour paste was only 196 nm and Zeta potential 30 mV. The bath containing ultrafine eolour paste had larger centrifugal stability. The deposite amount of the film with uhrafine colour paste was higher and the appearance was better and smoother than those of film with common colorant.
