Surface Treatment of Waste Rubber Powder and Its Application in Natural Rubber
摘要
Abstract
Surfaces of waste rubber powder（WRP） were modified by silane coupling agent KH550,and WRP/natural rubber（NR） composites were prepared.Effects of the content of waste rubber powder and silane coupling agent,particle size on the mechanical performances of the composites were investigated in detail through L16（45） orthogonal experiments and single factor experiments.Morphology of WRP and fracture surface of tensile test pieces were characterized by scanning electron microscopy（SEM）,and the thermal stability was also studied.The results show that the mechanical properties of the composite prepared by 80 mesh of 10wt%WRP and 1.5wt% silane coupling agent（KH550） is excellent,the tensile strength of the composite is 27.89MPa.SEM show the surface of WRP becomes rougher,surface area increases,the compatibility between WRP and NR is improved due to modification.The thermal stability of NR is little effected by adding modified WRP,which was confirmed by thermo gravimetric analysis.关键词
