| 研究了喷墨打印纸涂层中不同胶黏剂及其复配情况对油墨扩散和渗透的影响。实验以二氧化硅为颜料，以不同配比的乙烯-醋酸乙烯酯共聚物（VAE）和聚乙烯醇（PVA）为胶黏剂进行涂布，制成表面性能不同的喷墨打印纸。利用高压静电发射器和碾色仪在不同配方的涂层表面进行油墨扩散渗透实验和纸张吸收性测试，探讨了纸张涂层中胶黏剂种类、性能、配比对纸张亲水性和孔隙以及纸张吸墨性能的影响。研究发现，涂层中单独使用VAE或PVA作为胶黏剂时，油墨的扩散或渗透都比较严重，但当两者以适当比例复配时，油墨渗透和扩散均能得到有效控制，可以获得较大的印刷实地密度，纸张喷墨印刷适性得到提升。 |
| Abstract: |
| This article focused on the impact of different binder mixtures of coatings on ink spreading and permeation in inkjet paper． Silicon was used as pigment，and vinyl acetate copolymer(VAE) and polyvinyl alcohol(PVA) in different ratios were used as binder in this study．The spreading and permeation of the ink and the absorbability of the paper were assessed using high voltage electrostatic transmitter and printability tester．The results showed that the surface performance and printability of the paper were affected by the composition of the binder． With the decrease of VAE and the increase of PVA， the penetration and diffusion of the ink changed as well．When the binder mixture of VAE and PVA was used with proper ratio，a higher solid density of the print and definition could be achieved，which were better than using either one of them alone． |
