摘要：以碱木质素为原料,采用自组装催化氧化还原方法,制备了富含邻醌和邻酚的木质素/铜离子纳米颗粒(LNP/Cu)。将碱木质素和LNP/Cu用于纸张增强改性,以热压替代室温干燥制得增强纸,考察了添加剂和干燥方法对纸张强度性能的影响。结果表明,本研究所制的LNP/Cu呈球形,直径约300 nm,可在纸张中均匀分布,且对纸张的增强效果优于碱木质素。热压干燥可以增强木质素和纤维间的相互作用,相比于无添加剂、室温干燥制得纸张,LNP/Cu作添加剂并结合热压干燥(120℃、0.14 MPa、10 min)制得增强纸的抗张指数、耐破指数和撕裂指数分别增加27.5%、51.0%和9.6%,透气度降低38.8%。
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%.
