PP/TiO_2(KH–560)-g-AN/复合材料抗老化性能

Anti-ageing Property of PP/TiO_2(KH–560)-g-AN Composite

向聚丙烯(PP)内添加抗老化剂[TiO_2(KH–560)-g-AN]改善PP的抗老化性能。通过紫外可见光谱测试仪分析了TiO_2,KH–560,PAN,TiO_2(KH–560),TiO_2(KH–560)-g-AN紫外吸收效果,测定了在0,500,1 000,1 500,2 000,2 500 h老化时间下,PP/TiO_2(KH–560)和PP/TiO_2(KH–560)-g-AN复合材料的拉伸性能。结果表明,TiO_2,PP/KH–560,PAN,TiO_2(KH–560),TiO_2(KH–560)-g-AN都有较好的紫外吸收效果;PP/TiO_2(KH–560)和PP/TiO_2(KH–560)-g-AN复合材料的拉伸数据对比结果表明,当PP∶TiO_2(KH-560)-g-AN=100∶5时,PP的抗老化性能达到最好。

[TiO2（KH–560）-g-AN] was added to the polypropylene（PP） to improve the anti-ageing property of PP. Ultraviolet absorption effect of the TiO2,KH–560,PAN,TiO2（KH–560）,TiO2 （KH–560）-g-AN were analyzed by UV visible spectroscopy,and tensile properties of PP/TiO2（KH–560） and PP/TiO2（KH–560）-g-AN composites were determined at aging time of 0,500,1 000, 1 500,2 000,2500 h. The results show that TiO2,KH–560,PAN,TiO2（KH–560）,TiO2（KH–560）-g-AN have a good UV absorption effect. Tensile data of PP/TiO2 （KH–560） and PP/TiO2（KH–560）-g-AN composites were compared, it is concluded that when PP：TiO2 （KH-560）-g-AN=100：5, anti-aging performance of PP reach to the best.
