摘要: |
具有特殊层状结构的双氢氧化物(LDHs)作为润滑添加剂能极大地降低机械系统的摩擦和材料磨损,但在摩擦学领域对该材料的研究还相对较少。概述了 LDHs 的结构、性能和制备方法,并对不同制备方法进行比较和评价,重点综述 LDHs 材料作为油基、脂基以及水基润滑添加剂时的摩擦学行为。相关研究结果表明:LDHs 材料作为油基、脂基以及水基润滑添加剂时可以形成含有金属氧化物的保护膜,该保护膜具有高耐磨性和自润滑能力,可以达到减摩降磨的效果。但是 LDHs 材料作为油基润滑添加剂时,存在尺寸效应以及分散稳定性差的问题,成为制约其广泛应用的关键因素。通常采用表面改性剂来改善 LDHs 材料在润滑油中的分散性,如月桂酸、油酸和油胺等。对于层状双氢氧化物的研究和应用具有参考意义。 |

Abstract: |
Layered double hydroxides (LDHs) with special layered structure as lubricant additives can remarkably reduce the friction and material wear of mechanical systems, but little research has been devoted to this material in the field of tribology. The structure, properties and preparation methods of LDHs are reviewed, the different synthesis methods of LDHs are further compared and evaluated. Moreover, the tribological behavior of LDHs materials as oil based, grease based and water based lubricant additives are reviewed. Relevant research results show that LDHs materials as oil, grease and water-based lubricant additives can form a protective film containing metal oxides, which has high wear resistance and self-lubricating ability, and the protective film can also achieve the effect of friction reduction and wear reduction. However, when LDHs are used as oil-based lubricant additives, there are problems of size effect and poor dispersion stability, which become the key factors limiting its wide application. Surface modifiers are usually used to improve the dispersibility of LDHs materials in lubricants, such as lauric acid, oleic acid and oleylamine. This paper is a reference for the research and application of LDHs. |
