摘    要:采用玻璃微珠(GB)对高密度聚乙烯(HDPE)进行增韧改性。通过扫描电子显微镜、偏光显微镜和力学性能测试考察了偶联剂处理、基体韧性、玻璃微珠粒子用量、粒径大小和结晶等因素对HDPE/GB体系微观形态和性能的影响。结果表明,偶联剂可以明显改善空心玻璃微珠在基体中的分散,对于HDPE/GB体系,要求基体的最低冲击强度为5.0~5.5KJ/m2。玻璃微珠用量25%,粒径2.5μm时,冲击强度可达38.0kJ/m2。

关 键 词:高密度聚乙烯  空心玻璃微珠  增韧  偶联剂。

Abstract:Polyethylene(PE) was blended with hollow glass beads. The effect of various processing parameters on the properties of the blends were investigated, including the surface treatment of glass beads, toughness and crystallinity of the matrix,diameter and content of glass beads, using scanning electron microscope,polarizing microscope, and mechanical property testing. It is obvious that the silane coupling agent was beneficial to the dispersion of glass beads in the matrix. In order to achieve a high toughness of the blends, the matrix should possess an initial toughness above 5.0kJ/m2.The impact strength of composites is 38.0kJ/m2, When the Glass Bead content is 25% , diameter is 2.5μm .
Keywords:high-density polyethylene  hollow glass beads  toughness  coupling agent
