| 摘要: |
| 目的 研究微纤化纤维素作为添加剂对喷墨打印纸涂层性能的影响。方法 以胶体二氧化硅为颜料，采用聚乙烯醇为胶黏剂，通过改变微纤化纤维素的添加量（0, 0.3, 0.5, 0.8, 1份）制备5组涂料，经过涂布、干燥、压光得到5种喷墨打印涂布纸，通过对涂料的粘度、纸张的物理性能、喷墨打印质量和动态渗透性等进行分析，研究微纤化纤维素对喷墨打印纸涂层性能的影响。结果 微纤化纤维素可以降低喷墨打印纸涂层的粗糙度（47%），提高喷墨打印纸涂层的表面强度（36.7%），并对喷墨打印质量和涂层渗透性有很好的改善效果，并发现表面涂层被水浸透的时间与喷墨印刷性能有很好的相关性。结论 当微纤化纤维素用量为0.5份左右时，纸张的喷墨打印性能最优。 |

| Abstract: |
| The work aims to study the influence of MFC as additive on the properties of inkjet paper coating. Colloidal silica was used as the pigment and PVA as the binder. Five groups of coating were prepared by changing the MFC additive amount (0, 0.3, 0.5, 0.8 and 1). Five kinds of inkjet coated paper were obtained through coating, drying and press polishing. Based on the analysis of the viscosity of coating, physical properties of paper, inkjet printing quality and dynamic permeability, the influence of MFC on inkjet paper coating was studied. MFC could reduce the roughness of inkjet paper coating by 47%, enhance the surface strength by 36.7% and improve the quality of inkjet printing and coating permeability. Meanwhile, it was found that the soaking time of surface coating had good correlation with inkjet printing performance. When the amount of MFC is about 0.5, the paper has the optimal inkjet printing performance. |
