采用共混法合成了空心玻璃微球/聚氯乙烯(PVC)复合材料,空心玻璃微球使用前先用硅烷偶联剂KH-550进行了表面改性。通过高倍光学显微镜、红外分析仪、电子拉力机、邵氏硬度检测仪等手段研究了空心玻璃微球的含量对PVC抗拉强度,冲击强度和硬度等性能影响。结果表明:随着玻璃微球含量的逐渐增加,PVC复合材料的拉伸强度先增加后降低,伸长率不断降低,冲击强度略微下降,而硬度不断增加。
採用共混法閤成瞭空心玻璃微毬/聚氯乙烯(PVC)複閤材料,空心玻璃微毬使用前先用硅烷偶聯劑KH-550進行瞭錶麵改性。通過高倍光學顯微鏡、紅外分析儀、電子拉力機、邵氏硬度檢測儀等手段研究瞭空心玻璃微毬的含量對PVC抗拉彊度,遲擊彊度和硬度等性能影響。結果錶明:隨著玻璃微毬含量的逐漸增加,PVC複閤材料的拉伸彊度先增加後降低,伸長率不斷降低,遲擊彊度略微下降,而硬度不斷增加。

Hollow glass microspheres (HGS) filled PVC composites are prepared by blending, and before used, HGS is modified with silane coupling agent KH - 550. The effect of the content of HGB on the tensile strength, impact strength and hardness of the composites are studied by high resolution optical microscopy, infrared analyzer, electronic testing machine and hardness tester. The result shows , with the increasing of HGS content, the tensile strength of the PVC composites firstly increases and then decreases, the elongation kept on decreasing, impact strength decreased slightly, while the hardness kept on increasing.
