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; In addition, liquid lubricating oil is inconvenient in transportation, packaging and storage

Abstract

The invention discloses microencapsulated lubricating oil. The microencapsulated lubricating oil is obtained through the following steps that lubricating oil and mixed emulsifiers are mixed evenly according to the mass ratio of 16:3; a part of a PVA water solution is poured into the mixture at the temperature ranging from 80 DEG C to 85 DEG C; the remaining PVA water solution is added into the mixture after the mixture is stirred for 10 minutes; the mixture is subjected to emulsification; NaCl is added into the mixture in the stirring process, the mixture is stirred for 30 minutes, and then an emulsion is obtained; an tetraethyl orthosilicate and acetic acid solution is slowly added into the emulsion and stirred for 3 hours at the temperature of 55 DEG C; initiating agents are added into the emulsion, the emulsion is heated for 5 hours at the temperature of 75 DEG C, subjected to centrifugal separation, washed and dried, and finally the microencapsulated lubricating oil is obtained. A lubricating oil coating material is excellent in performance and capable of being widely applied to high-load and high-temperature mechanical friction parts and components needing to be properly protected in aerospace, machinery, electronics, chemical industry, ships and other industrial sectors.

Description

technical field [0001] The invention belongs to the technical field of microencapsulated lubricating oil, in particular to a microencapsulated lubricating oil, a lubricating oil coating material and a preparation method thereof. Background technique [0002] Microcapsule lubricating coating technology is a technology that firmly bonds microencapsulated lubricating oil, wear-resistant additives and other fillers to the friction surface of the moving pair with the help of a binder to lubricate, reduce and protect against wear. It is applied to the friction surface by spraying, brushing, dipping, etc. to solidify and form a film. The formed film material is called microcapsule lubricating film. [0003] Lubricating oil is generally a non-volatile oily lubricant, which can be used on various types of machinery to reduce friction, protect machinery and processed parts as a liquid lubricant, and have excellent performances such as lubrication, cooling, rust prevention, cleaning, s...
