High-strength and high-gas-barrier plastic packaging liners have emerged as competitive products with promising potential application in the field of Type IV hydrogen storage cylinders. Ternary composites, which contain PA6, organically modified montmorillonite (OMMT), and maleic anhydride grafted polyolefin elastomer (POE-g-MAH), have been proposed as possible material for this application. To achieve the goal of developing this material, the influence of material formulation on various properties such as mechanical, microstructure, gas barrier, thermal stability, and flow properties of the composites was investigated. The results show that the composites with 3 wt% OMMT had the best gas barrier and mechanical properties. Additionally, the effect of rotational molding process parameters on the wall thickness of the plastic liner was studied. Process parameter regulation methods were proposed to improve wall thickness consistency of the products. The investigation shows that the composites containing 3 wt% OMMT had the best wall thickness consistency of the products.

滚塑法生产的聚酰胺6/有机改性蒙脱石/马来酸酐接枝聚烯烃弹性体复合材料的机械性能和气体阻隔性能

高强度、高阻气性塑料包装内衬已成为IV型储氢瓶领域的拳头产品，具有广阔的应用前景。含有 PA6、有机改性蒙脱土 (OMMT) 和马来酸酐接枝聚烯烃弹性体 (POE-g-MAH) 的三元复合材料已被提议作为该应用的可能材料。为了实现开发这种材料的目标，研究了材料配方对复合材料的机械、微观结构、气体阻隔、热稳定性和流动性能等各种性能的影响。结果表明，OMMT含量为3%的复合材料具有最佳的阻气性能和力学性能。此外，还研究了滚塑工艺参数对塑料内衬壁厚的影响。提出了提高产品壁厚一致性的工艺参数调节方法。研究表明，含有3%wt%OMMT的复合材料制品的壁厚一致性最好。
