摘　　要： 该研究应用HCR-575型润滑脂黏附性测定仪测定了不同黏度基础油、不同主稠化剂含量、不同牌号微晶蜡含量以及不同分子量聚异丁烯对钢丝绳表面脂的黏附性能影响,最终得出以下结论:随着基础油100℃运动黏度的增大,钢丝绳表面脂的黏附性能明显提高;随着低分子量聚丙烯和聚乙烯含量的增加,钢丝绳表面脂的黏附性能均有明显提高,相比而言,聚乙烯在这方面比聚丙烯更有优势;微晶蜡的含量在一定范围内,可以改善钢丝绳表面脂的黏附性能,微晶蜡的牌号越大,加入量越多,对钢丝绳表面脂的黏附性能越不利;聚异丁烯对提高钢丝绳表面脂的黏附性能具有明显效果,但在加入量方面受到一定限制。 The influences of different viscosity base oil,different main thickener content,microcrystalline wax content for different grade and polyisobutylene with different molecular weight on the adhesivity of wire-rope surface grease were studied by the HCR-575 type grease adhesion tester. It was found that the adhesivity of wire-rope surface grease can be improved obviously by increasing the base oil viscosity at 100 ℃. More low molecular weight polypropylene and polyethylene can greatly improve the adhesivity of wire-rope surface grease,and that polyethylene is better than polypropylene. The content of microcrystalline wax can improve the adhesivity of wire-rope surface grease in a certain range. The higher microcrystalline wax grade,the more wax added,the worse adhesivity of wire-rope surface grease is. Polyisobutylene has obvious effect on improving the adhesivity of wire-rope surface grease,but it is restricted by the amount.
