天然微纳米纤维素的制备及其对纸张性能的影响
Preparation of natural micro-nanocellulose and its effect on paper properties
摘要
Abstract
Different contents of cotton fiber and wood fiber micro-nanocellulose were added in the preparation process of hand-made paper,and the effects of different kinds of micro-nanocellulose and its addition amount on the resistance of paper were studied.Micro-nanocellulose of cotton fiber and wood fiber were prepared from cot-ton pulp board and bleached-broadleaf wood pulp board,respectively,after pretreatment with low eutuity sol-vent(DES),followed by high pressure homogenization and mechanical dissociation.In the process of making paper,the additional amount of cotton fiber micro-nanocellulose was 0,2.5%and 5%,respectively.The addi-tional amount of lignocellulose and micro-nanocellulose were 2.5%and 5%respectively.The results showed that when the cotton fiber micro-nanocelluloses content was 5%,the physical comprehensive performance of pa-per was the best,the bursting index increased from 3.20 kPa·m2/g to 3.69 kPa·m2/g,the tensile index increased from 30.71 N·m/g to 36.71 N·m/g,and the opacity increased from 86.37 to 87.96.The experimental results showed that the addition of two kinds of micro-nanocellulose could improve the breaking index and tensile in-dex of paper,which laid a foundation for the modified properties of natural micro-nanocellulose paper.关键词
