| 摘 要： | 制备了聚丙烯(PP)／TiO2纳米复合材料，用氙灯耐气候试验机对该复合材料进行人工加速老化试验。采用紫外一可见光光谱法分析了纳米TiO2等粉体材料的紫外吸收性能；分析了PP／TiO2纳米复合材料的红外光谱并探讨了抗老化机理；对比研究了纯PP和PP／TiO2纳米复合材料老化期间力学性能的变化规律。结果表明，纳米TiO2能赋予PP优异的耐候性能，延长制品的户外使用寿命。

| Abstract: | The polypropylene/titania (PP/TiO 2) nano-composite is prepared, and it is degradated by accelerated aging with xenon arc lamp meatherproof test. The absorbing capability for ultraviolet radiation of nano-TiO 2 is analyzed by UV-VIS spectrum. The FTIR spectrum of PP/TiO 2 nano composite is studied. The mechanism of aging resistance of PP/TiO 2 nano composite is also discussed. The variational law for mechanical properties of pure PP and PP/TiO 2 nano composite during the aging period is studied in contrast. The results show that nano-TiO 2 can endue PP with excellent weatherproof property and can prolong survived life of the outdoor products. |
