摘要
以聚乙烯高分子添加不同含量石墨烯双螺杆挤出制备的复合材料为基材,利用单螺杆精密线材生产线制备了基于熔融沉积成型(FDM)的3D打印样条。通过XRD和SEM对复合材料力学性能、导电性能、导热性能进行了测试表征,得到了样品的屈服应力点以及不同石墨烯含量下样品的导电、导热规律。结果表明,用该方法制备的纳米复合材料粒径分布均匀,其3D打印线材可用于聚乙烯基石墨烯复合多孔球形阻隔防爆材料3D打印。
The 3D printing wire based on fused deposition modeling ( FDM) were successfully prepared by single-screw extruder,whose raw m aterials were made by using polyethylene based composites filled with different graphene content by twin-screw extruder. The mechanical properties, electrical conductivity and thermal conductivity of the composites were characterized by XRD and SEM. The yield stress point and the conductivity and thermal conductivity of the composites with different graphene content were obtained. The results show that the particle size distribution of the nanocomposites prepared by this method is uniform,and the wire of polyethylene-based composites filled with graphene can be used for 3D printing of porous spherical barrier and explosion-proof materials.
