| 目的 探索纸包装废弃物的高附加值利用途径。方法 以废瓦楞纸箱、 办公废纸和废包装纸板作为原料， 采用硫酸法降解制备纳米纤维素； 利用所制备的纳米纤维素作为添加剂， 加入过氧化氢氧化淀粉胶黏剂中， 研究了不同原料、 不同添加量的纳米纤维素对淀粉胶黏剂性能的影响。结果 纳米纤维素的添加改良了氧化淀粉胶黏剂， 当纳米纤维素的添加量为1%时， 可以使氧化淀粉胶黏剂获得最优良的性能， 此时黏度、 干燥速度以及粘接强度均达到最大值， 黏度为0.217 Pa·s， 4 h时的失水率为43.43%， 最大粘接强度为1.243 MPa， 3种性能分别提升了5.8%， 6.78%， 17.26%。结论 得到了不同原料制备的纳米纤维素对氧化淀粉胶黏剂性能的影响结果， 为废弃纸包装的循环再利用找到了一种方法。 |

| The aim of this study was to explore the high value-added utilization way of wasting paper. The waste corrugated carton, waste office paper and waste packaging cardboard were used as materials to make nano-cellulose with the sulfuric acid method. The H2O2-oxidized starch adhesives were prepared and modified by adding different amounts of nano-cellulose. The effects of material type and addition amount of nano-cellulose on the adhesive properties of oxidized starch were studied. The addition of nano-cellulose improved the properties of the oxidized starch adhesive. The best performance of the oxidized starch adhesives was obtained when the nano-cellulose content was 1% . Under the above condition, the viscosity, the drying speed and the bonding strength all reached their maximum values. The viscosity of the oxidized starch adhesive was 0.217 Pa·s, the water loss rate at 4 h was 43.43% and the maximum bonding strength was 1.243 MPa. Compared with the oxidized starch adhesives without nano-cellulose addition, these properties were improved by 5.8%, 6.78% and 17.26%, respectively. In conclusion, the effects of nano-cellulose prepared with different materials on the properties of the oxidized starch adhesives were obtained, and a method was found for the recycling of waste packaging paper. |
