| 中文摘要: |
| 为了提高纸板的力学性能和水蒸气阻隔性,采用热压法制备了聚己内酯(PCL) / 纸板双层复合膜。 分别使用质构仪、动态力学分析仪、透湿仪对材料的力学性能、动态热力学性能以及阻隔性能进行了评价,并对 PCL的热封性能和纸板的回收工艺进行了评估。 研究表明,与 PCL 复合后,纸板的拉伸强度提高了约 3 倍,弹性模量提高了约 5 倍,阻湿性也显著提高;PCL 的复合量和热封温度对材料的热封强度影响较大;纸板回收速度快,平均回收率可达到 99% 。 |
| 英文摘要: |
| In order to improve the mechanical property and water vapor barrier property of paperboard, PCL/ Paperboard bilayer film was prepared through thermo-compression technique. Tensile test, dynamic mechanical analysis (DMA) and water vapor permeability (WVP) test were conducted to assess the mechanical, thermodynamics and barrier behavior of the film before and after laminating. Heat-seal property of PCL and recycling test of paperboard was also explored. The results showed that the tensile strength of bilayar film is improved by 3 times, Young's modulus is improved by 5 times, and water vapor barrier property increases significantly after PCL laminating by comparison with the paperboard; content of PCL and platen temperature has significant influence on seal strength; paperboard recycling is fast and the average recovery is 99% . |
