【摘要】：目的为了解决传统装饰原纸大量加填所导致的填料流失严重、成纸强度较低和印刷适性不理想的问题。方法实验以传统生产工艺为基础,减少原纸在抄造过程中的加填量,通过对纸张进行涂布来提高其质量。对装饰原纸表面进行涂布后检测涂布装饰原纸的物理性能和印刷适性,并采用PDA动态渗透特性分析仪研究装饰原纸的表面孔隙开放程度和内部孔隙大小情况。结果涂布装饰原纸与市售高档装饰原纸相比,白度提高了0.6%,粗糙度下降了6%,匀度提高了33%,抗拉强度提高了340%,印刷色密度在暗调部分提高了21%,中间调部分提高了29%,亮调部分提高了55%。结论当原纸内钛白粉加填的质量分数为20%,涂料中二氧化钛和瓷土质量比为50∶50~60∶40之间的涂布装饰原纸的各项性能得到改善。
[Abstract]:Objective to solve the problems of serious loss of packing, low strength of finished paper and poor printing adaptability caused by large amount of filling in traditional decorative base paper. Methods the experiment is based on the traditional production technology to reduce the addition of the base paper in the process of copying and to improve the quality of the paper by coating it. After coating the decorative base paper, the physical properties and printing suitability of the decorative base paper were tested, and the opening degree of the surface pore and the internal pore size of the decorative base paper were studied by PDA dynamic permeation characteristic analyzer. Results compared with the high-grade decorative base paper sold in the market, the coated decorative base paper, The whiteness increased 0.6, the roughness decreased by 6 percent, the evenness increased by 33, the tensile strength increased by 340, the printing color density increased by 21 in the dark part, the middle by 29, and the bright by 55. Conclusion when the mass fraction of titanium dioxide in the base paper is 20, the properties of the coated decorative base paper with the mass ratio of titanium dioxide to porcelain clay between 50: 50 and 60: 40 are improved.
