Problems solved by technology

However, during the storage and use of lubricating oil, it is difficult for nano-metal particle additives with high chemical activity and surface activity to maintain chemical and physical stability for a long time, and the easy agglomeration of nano-metal particles makes it difficult to maintain dispersion stability in lubricating oil for a long time properties, which makes the application of nano-metal particle lubricating oil additives very limited

Abstract

The invention discloses an abrasion resisting lubricant, comprising 75-90 parts of base lubricant, 3-6 parts of viscosity improver, 3-6 parts of pour point depressant and 5-15 parts of nano boron silicide. Nano boron silicide abrasion resisting agent is added in the abrasion resisting lubricant of the invention, the nano boron silicide abrasion resisting agent is a novel high temperature resistinglubricant material with a layered structure, and has a hexagonal crystal system layered structure similar to silicon; boron and silicon between every two layers are overlapped in a stagger way, the shear resistance of sliding along inter-layer is small, thus being easy to slide; the invention has excellent lubricating property, can obviously reduce abrasion of an engine, increase power of the engine, prolong the service life of engine oil and save fuel oil.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and in particular relates to an anti-wear lubricating oil containing boron silicide anti-wear additives. Background technique [0002] At present, lubricating oil generally uses lubricating oil antiwear agents, which can reduce engine wear, increase engine power, prolong the service life of engine oil, and save fuel. In the prior art, nanomaterials are commonly used as lubricant antiwear agents. Due to their special physical and chemical properties, nanomaterials have received extensive attention and have been initially applied in many fields. However, during the storage and use of lubricating oil, it is difficult for nano-metal particle additives with high chemical activity and surface activity to maintain chemical and physical stability for a long time, and the easy agglomeration of nano-metal particles makes it difficult to maintain dispersion stability in lubricating oil for a long ti...
