摘　　要：研究了玻璃微珠填充超高分子量聚乙烯（ＵＨＭＷＰＥ）基复合材料的润湿及土壤粘附特性，分析了玻璃微珠的掺量、粒径与复合材料表面润湿性、土壤粘附特性的关系。试验结果表明：随着玻璃微珠掺量的增加，水对复合材料表面的接触角减小，土壤在复合材料表面的粘附力增大；当玻璃微珠的体积含量不超过９％时，玻璃微珠的加入不至于明显地降低ＵＨＭＷＰＥ的减粘降阻特性。由于“非光滑效应”，水膜在表面曳力的作用下力图拉离ＵＨＭＷＰＥ基体表面，土壤／基体间产生楔开应力，使土壤易于脱离基体表面。The wettability and soil adhesion performance of glass bead reinforced UHMWPE matrix composite were investigated. The results show that the increase of filler volume leads to the increase of the soiladhesion and wettability. When the filler volume is less than 9%, it will not affect the soil adhesionreducing performance obviously. The interaction of soilwaterspecimen surface was also analyzed. It is concluded that the reduction of soil adhesion of the glass bead/UHMWPE composite is caused mainly by its hydrophobic and chemical nonsmooth effects.
