| 目的 研究颜料协同作用对装饰原纸性能的影响，达到改善纸张表面结构、优化其物理性能的目的。方法 优选阔叶木浆和针叶木浆（有效成分的绝对质量比为4∶1）混合打浆至打浆度(SR)38°，再添加二氧化钛填料、PAM、PAE、硫酸铝等抄造装饰原纸；以PVA、阳离子淀粉为胶黏剂，加以蒸馏水、颜料（TiO2分别与Al2O3, Clay, Al2SiO5, SiO2协同）、分散剂、消泡剂、润滑剂、保水剂制备用于装饰纸表面用涂料，采用涂布机和压光机对原纸进行涂布压光，之后浸渍压板，采用凹版进行印刷，探究颜料复配涂布对原纸涂层结构和印刷适性作用。结果 颜料协同改性中添加一定的SiO2颜料有助于纸张表面被有效均匀地涂覆，并能观察到细小的颜料颗粒，形成良好紧密涂层结构，装饰原纸涂布含有SiO2协同作用颜料后，吸水高度提高了135%，平滑度提高了130%，干抗张强度提高了175%，湿抗张强度提高了160%。印刷性能方面，协同改性添加SiO2涂料涂布装饰原纸在相对较小的涂层厚度下纸张涂层具有良好的油墨接受性，有助于印刷油墨的吸收固着，进而抑制网点扩大和颜色整体阶调再现范围变大。结论 颜料协同改性涂布添加SiO2有助于改善装饰原纸的物理性能和印刷适性。 |

| The work aims to study the effect of pigment synergy on the decorative base paper, so as to improve the paper surface structure and optimize its physical properties. Decorative base paper was made with mixed pulp of fine hardwood and softwood (bone-dry ratio: 4∶1) which was beaten to freeness of 38°. Filler of TiO2, PAM, PAE, aluminum sulfate and other compositions was added as well. Surface coating was prepared by the adhesives of PVA and cationic starch and added with distilled water, pigment (TiO2 collaborated with Al2O3, Clay, Al2SiO5 and SiO2 respectively), dispersant, defoaming agent, lubricant and water-retaining agent. Decorative paper was coated and press polished with coating machine and calendar and then the pressing plate was dipped. Printing was conducted with the gravure to explore the effect of compound paint coating on coating structure and printability of base paper. Addition of certain SiO2 in synergistic modification was conducive to effective and uniform coating of paper surface and small pigment particles could be observed. In such case, good and tight coating structure was formed. After the decorative base paper was added with SiO2 in synergic modification, the water absorption, smoothness, dry tensile strength and wet tensile strength were improved by 135%, 130%, 175% and 160% respectively. In the aspect of printability, decorative base paper coated with SiO2 added in pigment synergistic modification showed good acceptance in relatively thinner coating, so that printing ink could be absorbed and fixed well. Moreover, dot enlargement could be controlled and the reproduction of overall tone was enlarged. Pigment synergistic modification added with SiO2 can help to improve the physical properties and printability of decorative base paper. |
