摘要
水滑石应用于机械摩擦系统,展现出良好的减摩抗磨性能。本文系统总结水滑石作为润滑油(脂)添加剂的摩擦性能及其影响因素,重点分析制备方法、阳离子半径、二价与三价阳离子比例、层间无机阴离子种类、有机阴离子插层、结晶度等因素对水滑石减摩抗磨性能的影响规律与作用机制,明确水滑石润滑材料结构成分设计基本原则与调控方向。基于研究现状,提出应深入加强水滑石润滑材料工业实验验证、水滑石对润滑油(脂)品质影响评价、水滑石与摩擦副表面交互作用基础研究等工作。
Hydrotalcite applied in mechanical friction system exhibits good friction and wear resistance.Friction performance of hydrotalcite as lubrication oil(grease)additive and its influence factors were summarized systematically in this paper.The mechanism and regulation of preparation methods,cation radius,the ratio of divalent and trivalent cations,the type of inorganic anions between layers,the intercalation of organic anions,crystallinity on the friction reduction and antiwear properties were analyzed comparatively.The basic principle and control directions of the structural composition design of hydrotalcite lubrication materials were clarified.Based on the research status,it was suggested that the industrial test verification of hydrotalcite,the evaluation of the influence of hydrotalcite on the quality of lubricating oil(grease),and the basic research about the interaction between hydrotalcite and the friction surface should be strengthened.
