Problems solved by technology

However, due to many defects in the use of lubricating oil, when the lubricating oil on the surface of the workpiece is squeezed during the movement, the workpieces are often in a boundary lubrication state, which not only causes waste but also pollutes the surrounding environment. affected

Embodiment Construction

[0024] Magnetic melamine resin lubricating oil, made by the following method:

[0025] (1) Pretreatment of lubricating oil: the magnetic additive is mixed with the dispersion system containing nano-silver sulfide lubricating oil, after being stirred by a powerful motor for 0.5h, it is evenly dispersed through ultrasonic waves and set aside; the preparation method of the magnetic additive comprises the following steps :

[0026] a. firstly mix disulfide trioxide, calcium chloride, vanadium pentoxide, magnesium oxide, sodium silicate and barium carbonate together, stir to obtain mixture A for subsequent use;

[0027] b. First take 80-85% of the total mass of mixture A, place it under a nitrogen environment, and continuously ball mill it until the particle size is 10-20 μm to obtain mixture B for later use, and then place the remaining mass of mixture A under a nitrogen environment, Continue ball milling until the particle size is 200-300nm to obtain mixture C for later use;

Abstract

The invention discloses magnetic melamine resin lubricating oil. The magnetic melamine resin lubricating oil is prepared through adding polyvinyl alcohol, sodium dodecyl benzene sulfonate and deionized water into a beaker, adding lubricating oil into the solution after dissolution, carrying out stirring emulsification, slowly pouring the emulsified lubricating oil into the melamine resin prepolymer through three processes, carrying out emulsification along with stirring under control of a stirring rate for 30min to obtain emulsified lubricating oil, adjusting pH to 2-3 through hydrochloric acid, adding 1-2% of chitosan into the lubricating oil, heating the mixture in a water bath at 70 DEG C for a reaction for 2h, carrying out suction filtration on the product, washing the product throughwater and drying the product for 24h to obtain the magnetic melamine resin lubricating oil. The magnetic melamine resin lubricating oil can be widely used for mechanical friction parts under large load and a high temperature in the field of aerospace, machinery, electronics, chemicals and ships.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil microcapsules, and particularly designs a magnetic melamine resin lubricating oil. Background technique [0002] Microcapsule technology refers to the technology of using film-forming materials to encapsulate solids, liquids or gases in them to form tiny containers with a diameter of tens of microns to thousands of microns. Microcapsule technology includes preparation technology and application technology, that is, using specific methods and equipment to wrap core materials of different shapes with wall materials to make microcapsules, and then apply the prepared microcapsules to various materials. The microcapsules are ruptured by means of pressure or radiation to release the core material, or the core material is directly diffused and released through the capsule wall to achieve the required performance. [0003] Microcapsule lubricating coating technology is a method of firmly bonding ...
