Effects of Fillers on the Transfer Properties of UV Waterless Offset Ink

摘要：

　　In order to investigate the effects of fillers on the transfer properties of UV waterless offset ink,four ink samples compound with different fillers(SiO2,CaCO3 and Talc) were prepared,the flow curve,thixotropy and ink transferred ratio were tested,and the effects of rheological properties on ink-transfer were discussed.The results show that:all of four ink samples show a typical shear thinning characteristics.Sample use SiO2 and CaCO3 as fillers has a higher viscosity,and with the increase of shearing rate,the viscosity decreased sharply.Sample use SiO2 and CaCO3 as fillers has the minimum thixotropic area,and the minimum thixotropy.Sample use SiO2 and Talc as fillers has the largest thixotropic area,and the largest thixotropy.Sample use SiO2 and CaCO3 as fillers has the highest ink transfer ratio.
