Description
Technical field
The present invention relates to a kind of tourmaline auxiliary molybdenum bisuphide class lubricating additive and preparation method thereof, belongs to mechanical lubrication
Technical field.
Background technology
Kollag and fluid lubricant have synergism for the lubrication of machinery, and lubricating oil and grease easily steam
Send out, when high load capacity is born, oil film can wreck, and lubricating ability will be lost at high temperature；By kollag and lubrication
Oil, fat are used in combination, and can meet the lubrication problem under harsh conditions, expand the use temperature range of lubricant, improve lubrication
The bearing capacity of oils and fatss, strengthens the aging performance of lubricant grease, protects plant equipment, increases economic efficiency.Molybdenum bisuphide is mesh
Front most widely used solid lubricant, the form and method for being adopted is more, such as powder, oil preparation, water preparation, or and other
Metal or macromolecular material constitute composite lubricated material.Patent CN 1513959A discloses a kind of molybdenum bisuphide oil based emulsions, by
The suspension of the two kinds of oil preparationes composition in molybdenum bisuphide and mineral oil, artificial oil or vegetable oil, as the additive of lubricating oil
Use.Find in actual use, simple molybdenum bisuphide suspension is easily settled, affect using effect.Patent CN
1468945A discloses a kind of method for preparing oil-soluble molybdenum bisuphide, adopts molybdenum trioxide for molybdenum source, using Oleic acid or hard
Fat acid is dressing agent, obtains the nanometer MOS 2 particle through modifying.In the case where there is air existence condition, molybdenum bisuphide makes
With temperature not above 400 DEG C, this is because molybdenum bisuphide is easily oxidized under the high temperature conditions molybdenum trisulfide；Do not occurring
In the ar gas environment of Oxidation, the coefficient of friction of molybdenum bisuphide is slightly above 0.2 at 1000 DEG C.It can be seen that, how to suppress lubrication
The oxidizing process of molybdenum bisuphide in oil additive, the use to molybdenum bisuphide is most important.To solve this problem, use at present
Method be addition from consumption-type antioxidant, such as Sb2O3, but this antioxidant consumes very rapid, economically impracticable.
Tourmaline (Tourmaline) crystal belongs to family's circulus borosilicate mineral of trigonal system, with pyroelectricity
And piezoelectricity, form weak electric field around under pressurized or heating condition, empty gas and water exist situation under promote bear from
The formation of son, mainly O2-(H2O)n、OH-(H2O)n, process do not consume energy；In addition, the bioactive molecule H for producing3O+Impurity can be attracted
Dirt.Tourmaline is a kind of using quite varied ideal green material.
The content of the invention
The problem of high cost is rapidly resulted in for existing molybdenum bisuphide antioxidant consumption, it is an object of the invention to carry
For a kind of tourmaline auxiliary molybdenum bisuphide class lubricating additive and preparation method thereof, the additive is by oil-soluble molybdenum bisuphide and oil
Dissolubility tourmaline powder is constituted.The lubricating additive of the present invention has extraordinary dispersibility and stability, in the auxiliary of tourmaline powder
Help the lower use temperature and service life that can be obviously improved molybdenum bisuphide of effect.
The purpose of the present invention is realized by technical scheme below：
A kind of tourmaline aids in molybdenum bisuphide class lubricating additive, is counted with the gross mass of the additive as 100%, wherein
Each component and its weight/mass percentage composition are as follows：

Wherein, the oil-based solvent is the one kind in mineral oil and artificial oil；
The oil-soluble molybdenum bisuphide is obtained for molybdenum bisuphide through surface organic modification, and oil-soluble tourmaline powder is electric
Stone powder is obtained through surface organic modification.
The surface organic modification is specially：
Under the conditions of 60 DEG C～90 DEG C, molybdenum bisuphide or tourmaline powder are mixed homogeneously with modified organisms, then placed
More than 2h；
The modified organisms be stearic acid, silane coupler, titanate coupling agent and silicone oil in one or two with
On mixture；
The addition of the modified organisms is the 0.5wt%～5wt% of molybdenum bisuphide or tourmaline powder.
Described oil-soluble molybdenum bisuphide particle diameter is 0.5～3 μm；
Described oil-soluble tourmaline powder particle diameter is 0.1～0.3 μm；
Tourmaline of the present invention aids in the preparation method of molybdenum bisuphide class lubricating additive, and step is as follows：At 5～60 DEG C
Under the conditions of, under agitation, oil-soluble molybdenum bisuphide and oil-soluble tourmaline powder being added in oil-based solvent in proportion, mixing is equal
It is even, it is finally transferred to 5～20min of ultrasound in ultrasonic container.
Wherein, mix homogeneously preferably stirs 5～30min.
Beneficial effect
During various machineries are lubricated, emollient component unavoidably bears very big pressure and hot conditionss, merely
In the presence of molybdenum bisuphide, can slowly be oxidized to the oxides such as molybdenum trisulfide, molybdenum trioxide and reduce performance；The present invention is by oil
Dissolubility tourmaline powder is used in mixed way with molybdenum bisuphide, tourmaline powder is pressurized when being heated can and oxygen, moisture form O2-(H2O)n、OH-
(H2O)n, reach and suppress the purpose of molybdenum bisuphide oxidizing process, and itself will not consume, principle is as shown in Figure 1.Can replace disappearing certainly
Consumption type antioxidant, with good economic benefit.
The lubricating additive of the present invention has extraordinary dispersibility and stability, can under the assosting effect of tourmaline powder
It is obviously improved the use temperature and service life of molybdenum bisuphide.
