摘要

本研究通过酸水解法制备纤维素纳米晶体(CNC)悬浮液,将其加入SiO2/羧甲基纤维素钠(CMC)涂料中,形成一种热升华转印纸生物基涂层.结果表明,CNC对SiO2/CMC团聚具有一定的分散作用.与SiO2/CMC涂层的热升华转印纸相比,CNC添加量为2.0％的SiO2/CMC/CNC涂层的热升华转印纸纵、横向抗张指数分别提高了9.2％、9.3％,平滑度提高了31.9％,透气度下降了46.0％,油墨吸收值下降了3.4％、干燥速度提高了24.3％,承印物平均色密度值由1.01升高至1.21,油墨转移率由80.1％升高至88.5％.由此可见,CNC添加提高了热升华转印纸的机械和热转印性能.

Abstract

In this paper,cellulose nanocrystal(CNC)suspension was prepared by acid hydrolysis method and added to SiO2/carboxyl methyl cellulose(CMC)coating to prepare a bio-based coating for thermal sublimation transfer paper.The results showed that CNC had a certain dispersion effect on SiO2/CMC agglomeration.Compared with SiO2/CMC coated thermal sublimation transfer paper,the transverse and longi-tudinal tensile fingers of SiO2/CMC/CNC coated thermal sublimation transfer paper with CNC content of 2.0％increased by 9.2％and 9.3％,the smoothness increased by 31.9％,and the air permeability decreased by 46.0％.The ink absorption value decreased by 3.4％and drying speed increased by 24.3％,the average color density of substrate increased from 1.01 to 1.21,and the ink transfer rate increased from 80.1％to 88.5％.It could be seen that the addition of CNC improved the mechanical and thermal transfer performance of thermal sublimation transfer paper.
