研制了纳米TiO2 /PP复合材料 ,采用紫外灯光源加速了材料的老化降解 ,并对比分析了纯PP材料和纳米TiO2 /PP复合材料力学性能的变化规律 ,研究结果表明纳米TiO2 能延长户外PP制品的使用寿命。
The nano-TiO2 / PP composites were fabricated. The aging degradation of the materials was accelerated by ultraviolet light source. The changes of the mechanical properties of pure PP and nano-TiO2 / PP composites were analyzed. The results show that nano-TiO2 can prolong outdoor PP products The service life.
