| 中文摘要: |
| 目的 采用可再生的纸浆纤维和功能塑料聚碳酸酯(PC)制备功能木塑复合材料，探究硼酸处理对复合材料相关性能的影响，进一步拓展材料在工程领域的应用。方法 配制质量分数为5%的硼酸溶液，将部分纸浆纤维放入硼酸溶液中浸渍2 h，将纸浆纤维与PC混合后，用双螺旋挤出机进行熔融加工，再用微型注塑机注塑成型,制备出复合材料。结果 经硼酸处理后的复合材料，在添加质量分数为30%的纸浆纤维时，复合材料的弹性模量达到4.31 GPa，比添加同样纤维含量的未经过硼酸处理的复合材料高16%:同时，与纯PC的弹性模量相比提高了90%。结论 采用硼酸处理可以提高纸浆纤维的热稳定性，可进一步提高复合材料的力学强度。PC是一种生活中常见的功能塑料，其本身具有优良的力学性能，硼酸的处理和纸浆纤维的加入使其力学性能进一步提升，有望作为结构材料应用于集装箱、托盘等方面，在包装领域有较好的应用前景。 |

| The work aims to prepare functional wood-plastic composite by renewable pulp fiber and functional plastic polycarbonate (PC) and investigate the effects of boric acid treatment on the properties of the composite to further expand the application of composite in the field of engineering. 5% (mass fraction) boric acid solution was prepared, and part of the pulp fibers were immersed in boric acid solution for 2 h. After mixed with PC, the pulp fibers were fused by a double spiral extruder and then subject to injection molding by a miniature injection molding machine to prepare the composite. The elastic modulus of the composite treated with boric acid reached 4.31 GPa when 30% pulp fiber was added, which was 16% higher than that of the composite without boric acid treatment but with the same fiber content. At the same time, compared with pure PC, the elastic modulus increased by 90%. The thermal stability of pulp fiber is improved by boric acid treatment, and the mechanical strength of the composite is further enhanced. PC is a common functional plastic in life, which has excellent mechanical properties. The treatment by boric acid and the addition of pulp fiber further improve the mechanical properties of the composite, which is expected to be used as a structural material for containers, pallets, etc., and has a good prospect in the field of packaging application. |
