| 摘要:本研究以针叶木浆为原料，通过不同打浆与压光工艺制备包装原纸，再经生物基防油剂施胶得到防油纸，结合孔隙结构表征、防油等级测试及力学性能分析，深入探讨了不同工艺条件下包装原纸的三维孔隙结构，并分析了包装原纸孔隙结构变化对生物基防油剂作用效果的影响。结果表明，针叶木浆打浆度从50 °SR提升至78 °SR，制得包装原纸的平均孔径由1.232 μm显著降至0.138 μm，透气度下降而紧度提升；在12级Kit防油等级要求下，提高打浆度可有效减少生物基防油剂用量。压光处理进一步优化了包装原纸的孔隙分布和表面平整性，针叶木浆打浆度78 °SR且经过压光和生物基防油剂施胶制得的防油纸在较低上胶量（0.55 g/m²）下防油等级仍可达11级。 |
| Abstract:In this study， softwood pulp was selected as raw materials to prepare packaging base paper through various beating and calendering processes， and oil-proofing paper was obtained after sizing with the bio-based oil-proofing agent. Combining pore structure characterization， oil-proofing grade testing， and mechanical property analysis， the three-dimensional pore structure of packaging base paper under different process conditions was deeply explored， and the influence of pore structure variation of packaging base paper on the using efficacy of bio-based oil-proofing agent was analyzed. The results indicated that when softwood pulp’s beating degree increased from 50 to 78 °SR， the average pore diameter of the prepared packaging base paper decreased significantly from 1.232 to 0.138 μm， resulting in a reduction in air permeability and an increase in density. Under the Kit 12 oil-proofing grade requirement， increasing the beating degree effectively reduced the usage of bio-based oil-proofing agent. The calendering process further optimized the pore distribution and surface smoothness of the packaging base paper. After calendering and sizing by bio-based oil-proofing agenty with at a low dosage of 0.55 g/m2， the prepared oil-proofing paper with softwood pulp’s beating degree of 78 °SR still achieved an oil-proofing grade of Kit 11. |
