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

[0022] Stabilized melamine resin lubricating ester, prepared by the following method:

[0023] (1) Pretreatment of lubricating oil: Mix the magnetic additive with the dispersion system containing nano-silver sulfide lubricating oil, stir it with a powerful motor for 0.5h, then disperse it evenly by ultrasonic, and set it aside;

[0024] (2) Add polyvinyl alcohol, sodium dodecylbenzene sulfonate and deionized water into the beaker, add to the pretreated lubricating oil in step 1 after dissolving, stir and emulsify for 10 minutes to obtain the emulsified lubricating oil dispersion system ;

[0025] (3) Slowly pour the emulsified lubricating oil dispersion into an equal volume of melamine resin prepolymer three times, control the stirring speed, and emulsify for 30 minutes;

[0026] (4) Adjust the pH value of the product in step 3 to 3 with hydrochloric acid, add chitosan with 1% by weight of lubricating oil, and heat and react in a water bath at 70°C for 3 hours;

[0027] (5) ...

Abstract

The invention discloses stable-type melamine resin grease. The stable-type melamine resin grease is prepared by the following method: adding polyvinyl alcohol, sodium dodecyl benzene sulfonate and deionized water into a beaker, adding into a lubricant after dissolution, and performing stirring emulsification to obtain an emulsified lubricant; slowly adding the emulsified lubricant into a melamine resin prepolymer for three times, controlling the stirring rotational speed, and emulsifying for 30 min; adjusting the pH value to 2-3 by hydrochloric acid, adding chitosan of which the weight is 1-2% of that of the lubricant, and performing heating reaction for 3 h in a water bath of 70 DEG C; and performing suction filtration, washing and drying on the product for 24 h to obtain an enhanced melamine resin microcapsule lubricant, and making the enhanced melamine resin microcapsule lubricant together with a thickening agent, an anti-oxidant, an anti-rust agent, an anti-wear agent, a stabilizer, a lubricating grease structural modifier and talcum powder into the stable-type melamine resin grease. The stable-type melamine resin grease can be widely applied to such heavy-load and high-temperature mechanical friction parts as aerospace, machinery, electronics, chemical engineering and ships.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil microcapsules, in particular to a stable melamine resin lubricating ester. 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 microcap...
