| 摘 要： | 采用碳氟化合物、有机硅化合物及碳氢化合物的等离子体涂层对渗透性颜料涂料纸进行表面改性,并研究其对UV光油吸收性的影响。通过水银孔隙率法的测试结果,得出等离子体涂层对纸张多孔结构没有影响的结论。采用X射线光电子能谱（XPS）和飞行时间二次离子质谱（ToF-SIMS）表征3种等离子体涂层的表面化学组分。碳氟化合物的等离子体涂层使UV光油接触角得到明显增加,而碳氢化合物的等离子体涂层对UV光油接触角没有明显的影响。当UV光油应用于一个存在压印力的凸版印刷单元时,表面化学组分的作用似乎变得很小。另外,本文还研究了在有无外部压力的情况下,UV光油黏度对吸收率的影响。

Influence of Surface Chemical Composition on UV-Varnish Absorption into Permeable Pigment-Coated Paper |

| Abstract: | Fluorocarbon,organosilicon,and hydrocarbon plasma coatings were used to modify the surface of permeable pigment -coated paper,and their impact on UV-varnish absorption was investigated.According to mercury porosimetry results, the plasma coatings had no influence on the porous structure of the paper.X-ray photoelectron spectroscopy（XPS） and timeof -flight secondary ion mass spectrometry（ToF-SIMS） results showed characteristic surface chemical compositions for each plasma coating.The fluorocarbon plasma coating increased the UV-varnish contact angles significantly,whereas the hydrocarbon plasma coating had no clear influence.When the UV varnish was applied with a flexography unit including nip pressure, the role of surface chemical composition seemed to become minimal.The viscosity of the UV varnish was shown to impact the absorption rate with and without external pressure. |
