改性木质素用于纸张增强的研究
Study on Modified Lignin Used for Paper Strengthening
摘要
Abstract
Using alkali lignin as raw material,lignin/copper ion nanoparticles(LNP/Cu)containing rich amounts of ortho-quinone and ortho-phenol were prepared using a self-assembly catalytic oxidation-reduction method.The alkali lignin and LNP/Cu were taken as paper reinforce-ment,via hot-press drying methods instead of room-temperature drying method to prepare reinforced paper.The effects of the additive and drying methods on paper strength properties were investigated.The results showed that the LNP/Cu prepared in this study exhibited a spheri-cal shape with a diameter of approximately 300 nm and could be uniformly distributed in the paper,demonstrating superior reinforcement ef-fects compared to alkali lignin.The hot-press drying method enhanced the interaction between lignin and fibers.Compared to paper produced without additives and using room-temperature drying,the tensile index,bursting index,and tearing index of the reinforced paper produced with LNP/Cu as an additive combined with the hot-press drying method(120℃,0.14 MPa,10 min)increased by 27.5%,51.0%,and 9.6%,respectively,while the air permeability decreased by 38.8%.关键词
