摘要
聚合物/粘土纳米复合材料是近几年聚合物材料改性的热点。利用自行研制的振动注塑装置研究低频振动对HDPE/纳米OMM T体系中纳米OMM T在基体中的分散性。结果表明,在低频高压下,无机粒子在基体中的分散性有了明显的改善,形成了明显的插层结构,使体系拉伸强度和冲击强度同时得到提高。
Polymer/clay nano-meter composites have been attracting people＇s attention recently at the modification of polymer materials. This paper investigated the influence of low-frequency vibration on the dispersion of nano-OMMT in the compound of HDPE/nano-OMMT by the selfmade vibration injection device. It testifies that the dispersion of nano-OMMT is improved, and the intercalation is so perfect that both of the tensile strength and the impact strength are enhanced in the situation of low frequency and high pressure.
