The invention belongs to the technical field of modified high polymer materials, and particularly relates to a polyamide composite material for a safety air bag shell and a preparation method, flat glass fibers are added into a PA6 material, the glass fibers are longer than conventional glass fibers in the width direction and have certain width and flatness, so that the PA6 and flat glass fiber composite material can be extruded in the extrusion process, and the product quality is improved. The extruded and sheared degree of the glass fibers is small, and the retention size of the glass fibers is large, so that the composite material has excellent flowability and tensile strength; in addition, the grafted POE toughening agent is added into the PA6 material, so that the PA6 and flat glass fiber composite material has excellent low-temperature and high-temperature impact toughness and has a relatively good application prospect in a safety airbag shell.
本发明属于改性高分子材料技术领域,特别涉及一种安全气囊壳体用聚酰胺复合材料和制备方法,通过在PA6材料中添加扁平玻纤,该种玻纤宽度方向比常规玻纤尺寸长,具有一定宽度及扁平度,使得PA6加扁平玻纤复合材料在挤出过程,玻纤被挤出剪碎程度小,玻纤保留尺寸大,使得复合材料具有优异的流动性和拉伸强度;并且通过在PA6材料中,添加接枝POE增韧剂,使得PA6加扁平玻纤复合材料具有优异的低温和高温冲击韧性,在安全气囊壳体中有较好的应用前景。
