摘要:本研究选用造纸工业中常用的玉米淀粉、木薯淀粉及小麦淀粉用于纸质文献加固，对比了不同淀粉的加固效果和耐老化性能。结果表明，相比玉米淀粉和木薯淀粉，小麦淀粉更适合用于纸质文献加固保护，在淀粉吸收量约为5.0 g/m²时，加固处理后纸张的抗张指数提升14.7%，撕裂指数提升29.0%，湿热老化3天后，纸张抗张指数下降1.9%，撕裂指数下降6.3%，色差变化为1.48，对纸张外观无明显影响。

Abstract:In this study， corn， tapioca， and wheat starches were selected for the reinforcement of paper literature， and the reinforcement effect and aging resistance of different kinds of starches were compared. The results showed that wheat starch was more suitable for the reinforcement and protection of paper literature， and when the starch absorption was about 5.0 g/m²， the tensile index of the reinforced paper increased by 14.7%， the tear index increased by 29.0%. After 3 days of hydrothermal aging， the tensile index decreased by 1.9%， the tear index decreased by 6.3%， and the chromatic aberration change was 1.48， which had no obvious effect on the appearance of the paper.
