| 摘要: |
| 目的 探讨CPAM-HPCS-PAE复合增强剂作为增干、 湿强剂在瓦楞原纸中的应用效果， 并与CPAM增强剂和CPAM/HPCS/PAE混合物比较增强效果。方法 将羟丙基壳聚糖 （HPCS）、 CPAM及PAE树脂通过交联反应制得 CPAM-HPCS-PAE 复合增强剂。结果 CPAM-HPCS-PAE 复合增强剂质量分数为0.5%时， 纸张具有较好的机械强度， 与单独使用CPAM增强剂和CPAM/HPCS/PAE混合物相比， 该复合增强剂不但能明显提高瓦楞原纸的干强性能， 而且还能显著改善其湿强性能。SEM及光散射系数检测结果表明， CPAM-HPCS-PAE复合增强剂的加入能够显著改善纸张纤维之间的交织， 增加纤维之间的结合面积， 从而对纸张起到增强作用。结论 CPAM-HPCS-PAE复合增强剂不但具有良好的增干强性能， 而且具有一定的增湿强性能。 |

| Abstract: |
| This work mainly discussed the usage of CPAM-HPCS-PAE complex as a strengthening agent of corrugating medium and the performance enhancement was compared with CPAM andCPAM/HPCS/PAE mixture. The strengthening agent was prepared with hydroxypropyl chitosan (HPCS), CPAM and PAE resin through the cross-linking reaction. All results showed that the optimal addition of CPAM-HPCS-PAE complex was 0.5% , and the dry and wet strength properties of the corrugating medium after the addition of this agent were improved compared with those of CPAM and CPAM/HPCS/PAE mixture. SEM and light scattering results indicated that the intertexture between the paper fibers and the fiber bonding area was efficiently improved after the addition of CPAM-HPCS-PAE complex, thus increasing the strength of paper sheets. In conclusion, both the dry and wet strength properties of the corrugating medium were significantly improved after the addition of CPAM-HPCS-PAE complex. |
