介绍了一种生物质石墨烯改性聚酰胺6母粒(GE/PA6母粒)的制备方法,即采用生物质石墨烯粉体、助剂与PA6粉体混合,经过双螺杆挤出机熔融挤出、造粒、干燥,制备得到GE/PA6母粒。该母粒含水率为5×10-5,热稳定性得到提高,过滤压力值(FPV)稳定。通过扫描电镜观察生物质石墨烯均匀分散在PA6中,达到纺丝要求。使用该GE/PA6母粒制备的改性锦纶6具有优越的抗菌性,其对金黄色葡萄球菌的抑菌率达到90%,对大肠埃希菌的抑菌率达到85%,对白念珠菌的抑菌率达到82%;同时也具有优异的远红外功能,其远红外发射率为0.88,远红外辐照温升达到2.3℃。
A preparation method of biomass graphene modified polyamide 6 masterbatch (GE / PA6 masterbatch) is introduced, that is, the biomass graphene powder and the auxiliary are mixed with the PA6 powder and melted through a twin-screw extruder Extrusion, granulation, drying, preparation of GE / PA6 masterbatch. The masterbatch moisture content of 5 × 10-5, thermal stability is improved, the filtration pressure value (FPV) stability. Scanning electron microscopy of biomass graphene dispersed in PA6, to achieve spinning requirements. The modified nylon 6 prepared by using the GE / PA6 masterbatch has excellent antibacterial properties, and has an antibacterial rate of 90% against Staphylococcus aureus, an antibacterial rate of 85% against Escherichia coli, Bacteriostasis rate reached 82%; also has excellent far-infrared function, the far-infrared emissivity of 0.88, far-infrared radiation temperature reached 2.3 ℃.
