| 摘 要： | 以纳米TiO2作为填料,制备耐磨蚀聚氨酯纳米复合材料.用相对抗磨损性法评价了聚氨酯纳米复合材料的冲蚀磨损性,通过扫描电镜观察聚氨酯纳米复合材料的磨损形貌,尝试解释纳米TiO2增强聚氨酯复合材料抗含沙冲蚀磨损性能的机理.试验结果表明,纳米粒子均匀分散于聚氨酯中,使聚氨酯弹性体耐磨蚀性得以提高.聚氨酯/TiO2纳米复合材料的抗冲蚀磨损性能分别是45#钢的10.67倍,2Cr13钢的6倍,纯聚氨酯的1.28倍,TiN/聚氨酯复合材料的1.09倍.

| Abstract: | Nanocomposite were prepared by nanometer TiO 2 and polyurethane.Erosion wear resistance of polyurethane nanocomposite was valued with relative erosion wear rates.The wear mechanisms of composites were discussed through examining and analyzing the worn surfaces with a scanning electron microscope.The results show that erosion wear resistance of polyurethane is increased with the dispersion of nanometer TiO 2,erosion wear resistance of Polyurethane/TiO 2 nanocomposite is 6 times of 2Cr13 stainless steel,10.67 times of 45 # steel,1.28 times of polyurethane and 1.09 times of TiN/polyurethane composite. |
