Problems solved by technology

The inventors of the present invention found that under boundary lubrication or mixed lubrication state, the pure water lubrication performance is poor, and the water film is easy to break, so that the metal surface is in direct contact, that is, solid-solid contact, which greatly limits its movement. Applications in the field of component and joint fluid lubrication

Embodiment 1

[0045] (1) Prepare graphene oxide solution using Hummer's improved method: first, cool a 1000ml dry flask in an ice-water bath for 5min, then add 100ml of concentrated sulfuric acid, add 2g of flake graphite, 1.2g of sodium nitrate, and 8.0g of high manganese during stirring Potassium acid), the reaction temperature was controlled at 5°C in an ice-water bath, and the reaction was carried out with magnetic stirring for 2 hours. Then, the flask was taken out, placed on a constant temperature heating magnetic stirrer, and reacted with magnetic stirring at 35° C. for 2 h. Finally, 150ml of deionized water was added, and then the reaction temperature was raised to 95° C. with a constant temperature heating stirrer, and magnetic stirring was continued for 1 hour to obtain a graphite oxide solution with a concentration of 50 mg / ml. Add deionized water to dilute the graphite oxide solution, and ultrasonically shake for 2 hours to obtain a graphene oxide aqueous solution, put it in the...

Abstract

The invention discloses a super-lubricity water lubricating additive and a preparation method thereof, a super-lubricity water lubricating agent and application thereof. The super-lubricity water lubricating additive is of a hollow spherical shell structure, and the hollow spherical shell structure comprises at least one layer of spherical shell; the spherical shell sequentially comprises a firstpolydopamine layer, a nano-particle layer, a second polydopamine layer and a graphene oxide layer from inside to outside, or the spherical shell sequentially comprises a first polydopamine layer, a nano-particle layer, a second polydopamine layer, a graphene layer and a third polydopamine layer from inside to outside; and nano particles of the nano particle layer are nano diamond, nano molybdenumdisulfide or nano tungsten disulfide. And the super-lubricating water lubricating additive is prepared into a uniform aqueous solution to obtain a super-lubricating water lubricating agent. The super-lubricating water lubricating additive provided by the invention is easy to adsorb on the dual surface, and nanoparticles released in the friction process and spherical graphene oxide or graphene cooperate to form rolling friction, so that the friction wear is reduced.

Description

technical field [0001] The invention relates to a super water slip lubricating additive, a super water slip lubricant, a preparation method and an application thereof. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Mechanical moving parts consume energy due to friction during movement, and wear and tear cause their failure and damage, which brings huge economic losses to people and causes environmental pollution. How to understand and control the friction and wear of key components such as motor vehicles and micro-nano mechanical components has become the key. Scientists have found that there is almost zero friction and wear between van der Waals solid surfaces in non-c...
