Mechanical and Tribological Properties of Nylon 1212 Modified With Brown Corundum Ash and Solid Lubricants

摘要

Brown Corundum Ash(BCA) was used to modify nylon 1212(PA1212), which is produced during the production of electric fused brown corundum alumina and will causes serous environmental pollution if it is not recycled. In order to improve the tribological property of PA 1212 composites, Graphite, M0S2 and PTFE were used. The composites were prepared by a twin-screw extruder through melt intercalation. The mechanical properties and the wear resistance of the PA1212/Brown Corundum Ash/graphite/MoS2/PTFE composite were studied. The shearing area of composite and the worn surfaces were examined by scanning electric microscope (SEM).
