摘要
采用偶联剂KH -5 5 0处理空心玻璃微珠 ,在宽广的用量范围内考察了玻璃微珠含量对PP复合材料拉伸强度、冲击强度、流变性能的影响 ;研究了复合材料的耐热性和相态结构 ,对材料冲击断裂面进行了扫描电镜分析。研究结果表明 :与未活化的玻璃微珠相比 ,填充活化玻璃微珠的复合材料的拉伸强度、冲击强度明显提高 ;一定用量的玻璃微珠填充PP不仅可以使材料的力学性能和耐热性能保持较好 。
Hollow microbeads are treated with coupling agent KH-550.The effect of the contents of hollow microbeads on the tensile strength,the impact strength,the rheological behavior and morphological structure of PP/microbeads composites are studied.Thermal resistance and phase structure of the system are analyzed.Results show that the tensile strength and impact strength of the activated microbeads filled PP are higher than those of unactivated ones.It is founded that the hollow microbeads not only maintains the mechanical properties of the system,but also decreases the cost of it.
