Abstract

In this paper, three kinds of micro-nano bamboo powder (MBP) and alkyl ketene dimer (AKD) were added to the polyvinyl alcohol/cellulose nanofiber (PVA/CNF) coating to prepare PVA/CNF/MBP coated paper and PVA/CNF/M-MBP/AKD coated paper. The results showed that MBP improved the oleophobicity of PVA/CNF coating, and the grease resistance grade of PVA/CNF/B-MBP and PVA/CNF/M-MBP coated papers reached the highest level, with a kit number of 12. Among the PVA/CNF/MBP coated papers, the PVA/CNF/M-MBP coated paper has the best hydrophobic properties, with the water contact angle and Cobb value of 74° and 21.3 g/m, respectively. In addition, when the AKD dosage was 0.2% in the PVA/CNF/M-MBP/AKD coating, the kit number of the coated paper was 11, the Cobb value was 15.2 g/m, the water contact angle was 103°, and the tensile strength was found to increase slightly. Therefore, compared with PVA/CNF coated paper, PVA/CNF/M-MBP/AKD coated paper has good strength and excellent hydrophobic and oleophobic properties.

摘要

本文将三种微纳米竹粉（MBP）和烷基烯酮二聚体（AKD）添加到聚乙烯醇/纤维素纳米纤维（PVA/CNF）涂层中，制备了PVA/CNF/MBP涂布纸和PVA/CNF/M-MBP/AKD涂布纸。结果表明，MBP提高了PVA/CNF涂层的疏油性，PVA/CNF/B-MBP和PVA/CNF/M-MBP涂布纸的耐油等级达到最高水平，试剂盒编号为12。在PVA/CNF/MBP涂布纸中，PVA/CNF/M-MBP涂布纸具有最佳的疏水性能，水接触角和科布值分别为74°和21.3 g/m²。此外，当PVA/CNF/M-MBP/AKD涂层中AKD用量为0.2%时，涂布纸的试剂盒编号为11，科布值为15.2 g/m²，水接触角为103°，拉伸强度略有增加。因此，与PVA/CNF涂布纸相比，PVA/CNF/M-MBP/AKD涂布纸具有良好的强度以及优异的疏水和疏油性能。
