摘要
采用经表面处理的纳米TiO2 、SiO2 来改善聚丙烯的抗老化性能 ,经热老化试验 ,加速人工老化试验 ,测定其冲击强度、熔点、熔融流动速率 ,表明其热老化性能变化不大 ,抗紫外线性能有明显提高。
Polypropylene improved the aging resistance property with the surface treated nanomaterials TiO 2,SiO 2 etc.,by thermal aging test and accelerated aging test to measure its impact strength,melting point and melt flow rate,show a slight change in aging resistance property but a remarkable change in the property of ultraviolet ray resistance The paper also studies the aging mechanism of PP modified by nanomaterial with the aid of IR spectrum
