Abstract
The invention relates to the technical field of lubricating grease, in particular to a lubricating grease composition for different electric picks and a preparation method thereof. The grease composition comprises a base oil, a thickener and an additive; the base oil comprises 60-80 parts of PAO, 20-25 parts of 500SN and 5-15 parts of naphthenic oil; the thickener is a composite aluminum-based soap of aluminum benzoate and aluminum stearate, wherein an aluminum source is aluminum carboxylate trimer; the mass ratio of the base oil to the thickener is 85: 15-95: 5. the lubricating grease composition for the electric pick has the characteristics of high temperature resistance, oxidation resistance, good wear resistance and the like, and can integrate lubricating grease used by electric picks of different sizes, so that the lubricating grease composition can meet the requirements of the electric pick under severe working conditions such as high temperature, high speed, high load and the like.
Description
Technical Field
The invention relates to the technical field of lubricating grease, in particular to a lubricating grease composition for different electric picks and a preparation method thereof.
Background
The electric pick is one kind of electric tool and is mainly used in hammering, crushing concrete, brick wall and ice block, and may be replaced with different kinds of tools for different operations. The electric pick is different from the electric hammer in that the electric pick has no rotation function, only has the impact function and has larger impact energy.
The electric pick mainly comprises a motor, a gear reducer, a crank connecting rod impact mechanism, a working tool, a power switch and the like, wherein the main lubrication parts are gears, cylinders, pistons, connecting rods and the like.
Compared with common electric tools such as electric hammers, angle grinders and the like, the electric pick has the advantages of being large in weight, relatively professional in electric tools, high in power and impact energy in the running process of the electric pick, high in requirements on lubricating grease performance, and good in high-temperature resistance, oxidation resistance and wear resistance. In addition, different lubricating grease is needed to be correspondingly used by electric picks with different sizes in the market at present, and the two lubricating grease cannot be mixed, namely if the lubricating grease applied to the low-power electric pick is applied to the high-power electric pick, the requirement of abrasion resistance of the lubricating grease cannot be met; and grease leakage occurs when the grease applied to the high-power electric pick is applied to the low-power electric pick. The problems cause that the electric pick lubricating grease is excessively complicated in the production and management processes.
Disclosure of Invention
In order to solve the technical problems, the invention provides the lubricating grease composition which can be uniformly applied to electric picks of different types and sizes and the preparation method thereof, and the actual requirements of the different electric picks are met.
As a first object of the present invention, there is provided a grease composition comprising a base oil and a thickener; the base oil comprises 60-80 parts of PAO, 20-25 parts of 500SN and 5-15 parts of naphthenic oil; the thickener is a composite aluminum-based soap of aluminum benzoate and aluminum stearate, wherein an aluminum source is aluminum carboxylate trimer; the mass ratio of the base oil to the thickener is 85: 15-95: 5.
the invention discovers that the components and the dosage of the base oil can effectively improve the performance of the lubricating grease and better meet the actual requirements of lubrication of different electric picks. Meanwhile, when aluminum carboxylate trimer is used as an aluminum source, only a small portion of the acid is necessary to complete the saponification process due to the pre-substitution of fatty acid and benzoic acid, and zero alcohol release can be achieved during the manufacturing process.
Preferably, the mass ratio of the total mass of PAO to 500SN and the naphthenic oil in the base oil is (6-9): 1.
preferably, the base oil has a kinematic viscosity at 40 ℃ of 260 to 300mm 2 /s。
Preferably, the aluminum content in the thickener is 5 to 6wt%.
