Description
Technical Field
The invention relates to a composition of a color lubricating grease, in particular to a color lubricating grease with good lubricating property and using layered borophosphate as a solid additive and a preparation method thereof, belonging to the technical field of lubricating grease preparation.
Background
Greases are stable semi-solid or semi-fluid products formed by dispersing a thickener in a liquid lubricant, and have unique rheological properties. Because of the inherent good properties of the lubricating grease, besides the general lubricating action, the extreme pressure, wear resistance, sealing and protecting actions of the lubricating grease are far superior to those of the conventional lubricating oil, so the lubricating grease is widely applied to the moving parts of various industrial machinery such as gears, bearings and the like.
In order to facilitate maintenance when the work is not stopped, a lubricating system of large-scale mechanical equipment such as a continuous casting machine, a wind motor, a blast furnace top machine and the like mostly adopts double-line centralized lubrication, and lubricating grease is supplied to a required lubricating point through a pipeline by a lubricating grease supply source; meanwhile, the oil quantity of each lubricating point needs to be adjusted, so that the optimal protection effect is achieved. The colored lubricating grease is used, so that whether the lubricating grease is delivered in place or not can be conveniently observed; after the colored grease is used, the condition that oil leakage occurs to the equipment is easier to detect. In addition, in the maintenance of the large-sized motor, whether the lubrication is failed or not is judged by observing the color change degree of the grease discharged from the motor. Traditional color lotionThe grease is generally blended with a specific pigment to prepare a color. Pigment species generally include cadmium Red (CdS nCdS), iron Red (Fe) 2 O 3 ) Inorganic pigments represented by the following and organic pigments represented by naphthol green B, sudan iii, oil-soluble orange, pigment yellow G, etc. [ chinese patent CN 111748400A; chinese patent CN101886017A; chinese patent CN 101886018A]. In general, the addition of these pigments only serves for toning in the grease and does not have a lubricating protection effect.
The solid lubricant is an important additive in the lubricating grease, and can play the roles of extreme pressure, bearing, wear resistance, friction reduction and cooperative reinforcement when subjected to harsh operating conditions such as high load, high temperature, strong radiation and the like. With the development of modern industrial technology, higher and higher requirements are put on the performance of the lubricating grease. Therefore, new solid lubricant additive materials are continuously developed to meet the requirements of different working conditions.
