纳米TiO_2/PP复合材料的研究

Study of Nano-TiO_2/PP Composite

研究了纳米TiO2 /PP复合材料的力学性能和耐老化性能。实验结果表明 ,添加 1%～ 2 %的纳米TiO2 可以明显改善PP材料的抗冲击性能 ;纳米质量分数在 1%～ 4%范围内对复合材料的拉伸强度几乎没有影响 ;而添加少量的纳米TiO2 可以大大提高PP材料的耐紫外光老化性能 ,说明纳米TiO2 对紫外光有极强的吸收能力。TiO2 /PP复合材料具有良好的耐侯性 。

s The mechanical properties and ageing resistance of nano TiO 2/PP composite were studied.The results showed the impact resistance of the composite could be improved obviously by adding 1%～2% of nano TiO 2.The addition of 1%～4% of nano TiO 2 had no effect on the tensile strength of the composite,but could improve the UV resistance of the composite greatly,showing great UV absorption of nano TiO 2.TiO 2/PP composite had good ageing resistance and longer service life at outdoor.
