摘要
利用等离子体对废橡胶胶粉(SRP)进行了表面处理,并将其与聚氯乙烯(PVC)进行共混,研究了等离子体处理前后胶粉/PVC复合材料的结构和性能。结果表明,胶粉等离子体改性后,不仅提高了胶粉与PVC之间的粘接强度,而且提高了PVC/SRP复合材料的力学性能。采用氧等离子处理2min后,PVC/SRP复合材料具有较好的力学性能。扫描电镜观察(SEM)表明,未处理胶粉/PVC复合材料的冲击断裂形貌表现为胶粉的脱落;等离子体处理后胶粉/PVC复合材料冲击断裂形貌则表现为胶粉的本体破坏。
The scrap rubber powder (SRP) was treated with plasma and then compounded with the polyvinyl chloride (PVC). The structure and properties of the PVC composites filled with untreated or plasma treated SRP were studied. The results show that the adhesive strength between the SRP and the PVC and the mechanical properties of the PVC/SRP composites are improved after the SRP was treated with plasma. The PVC/SRP composites have better mechanical properties if the SRP was treated for 2 min in the oxygen plasma. The Scanning Electron Microscope (SEM) observations show that the SRP is pulled out from the PVC matrix in the untreated SRP/PVC composites, but the SRP itself is broken in the plasma treated SRP/PVC composites.
