【摘要】 本文采用直接共混法和母料共混法制备MgO/LDPE纳米复合材料,讨论了混料方式、母料加料顺序对纳米复合材料分散性、力学及电学性能的影响,寻求最佳的共混工艺。结果表明:采用母料法共混制备的复合材料分散效果优于直接法,此时纳米粒子分散均匀,团聚现象不明显,粒径为56nm～96nm,并且与直接法制备的复合材料相比拉伸强度、断裂伸长率、体积电阻率及击穿场强都有很大程度地提高。更多还原

【Abstract】 The MgO/LDPE nano-composite was prepared by the method of direct blending and masters batch blending. The effect of blend method and feeding order of the master batch on dispersion and mechanical property as well as electrical properties of nano-composites was investigated to obtain the proper processing technology.Result showed that the dispersion of nano-composite prepared with master batch blending was better than the one with direct blending. In this condition the nano-particles was uniform dispersion and unobvious agglomeration,particle diameter distributed from 56nm to 96nm.The tensile strength,elongation at break,volume resistivity and breakdown strength of nano-composite prepared with master batch blending were improved comparing with nano-composite prepared with direct blending,更多还原
