Embodiment Construction

[0014] 1. Preparation of nanoparticle powder

[0015] Hydrolyze borate and deionized water in a high-speed stirring mixer mixer, add sodium nitride and hydrazine hydrate respectively after the borate is completely dissolved, slowly raise the temperature and continue stirring until completely dissolved; add coupling agent and ethanol, Heating; add ammonium molybdate when the solution is transparent; add copper sulfate after the solution is stable; Salt Alcohol Sol. The material components used are calculated based on the product components. The sol is pumped into the autoclave, and the air in the autoclave is exhausted with nitrogen. After the autoclave is sealed, it is heated slowly, and samples are taken regularly to observe the shrinkage and aging degree of the gel until the double salt nuclei gel is in the autoclave. Until the aging is formed; after the gel is qualified, it is pressed into the airgel hybrid generator with a high-pressure pump in time, pressed out from the...

Abstract

The invention relates to a nanoscale ceramic metal additive for lubricating oil (grease) and preparation, which is a composite fluid comprising kubonit, molybdenum and copper powder. The powder is a nanoscale globular solid particulate which is formed by covalent bond structure of kubinit and molybdenum and coordinate bond of copper. The kubinit is globular framework, molybdenum is coated around the globular kubinit framework, and the copper is combined with the crystal defecting portion of the globular framework in the shape of point and sheet. The proportion of kubinit, molybdenum and copper in the powder is 7-8.5:1-1.5:0.5-1.

Description

Technical field: [0001] The invention belongs to ceramic metal additives Background technique: [0002] As lubricating oil additives, nanomaterials have been recognized at home and abroad in recent years for their excellent functions such as wear resistance, wear reduction, and mechanical load improvement. There are unit metal and binary metal nanomaterials and unit and binary ceramic nanomaterials; but due to the single performance of the unit body, the ideal effect cannot be achieved in use; and the use effect of pure metal base and pure ceramic base is not ideal . Invention content: [0003] A nanoscale ceramic metal additive for lubricating oil (grease) of the present invention, it is the composition liquid that contains boron nitride, molybdenum, copper powder; The powder is boron nitride and molybdenum with covalent bond structure 1. A nano-scale spherical solid particle formed by copper with a coordination bond structure; boron nitride is a spherical skeleton, mol...
