摘要:

采用直接法制备聚脲润滑脂,考察了五种添加剂对聚脲润滑脂极压抗磨性能的影响。结果表明,五种添加剂均与聚脲润滑脂具有良好的相容性,且对聚脲润滑脂的胶体安定性等基本无影响,并可增强其热稳定性;添加剂可显著强化聚脲润滑脂的极压抗磨性,含硫磷的复合多效添加剂对聚脲润滑脂极压抗磨性能的提升作用相对较好。研究结果可为聚脲润滑脂极压抗磨性能的改善提供可参考的基础,使其综合性能达到相对最优,从而增强聚脲润滑脂在高负荷、高速机械设备等苛刻工况下的实际使用性能。

Abstract:

The direct method was used to prepare polyurea lubricating grease, and the effects of several different types of additives on the extreme pressure and anti?wear performance for polyurea lubricating grease were investigated and studied. The results demonstrate that several types of additives have good compatibility with polyurea grease, and they have little undesirable influence on colloidal stability of polyurea grease, and they can also enhance thermal stability of polyurea grease. Moreover, the addition of additives can significantly improve the performance of extreme pressure and wear resistance for polyurea lubricating grease. And in the experiments, it was found that the composite multifunctional additive containing sulfur and phosphorus has a relatively better effect on improving the extreme pressure and wear resistance of polyurea lubricating grease. The research results can provide a reference basis for the improvement of extreme pressure and anti?wear property for polyurea lubricating grease, achieving a relatively optimized comprehensive performance, thereby enhancing its practical utilization performance under the harsh working conditions for high load and high speed mechanical equipment.

Key words: Additives, Polyurea lubricating grease, Performance indicators, Extreme pressure and wear resistance
