Specific embodiment
Below in conjunction with the embodiment of the present invention, technical solution of the present invention is clearly and completely described.Implement below
Example is only used for clearly illustrating technical solution of the present invention, therefore is intended only as example, and cannot be used as a limitation and limit this hair
Bright protection scope.
Experimental method in following embodiments is unless otherwise specified conventional method.Examination as used in the following examples
Material is tested, is to be commercially available from regular shops unless otherwise specified.Quantitative test in following embodiment, is respectively provided with three
Secondary to repeat to test, data are the average value or mean+SD of three repeated experiments.
The present invention provides a kind of wind-powered electricity generation graphite gear oils, and raw material components are by weight percentage, comprising: oiliness improver 1%-
8%, extreme pressure anti-wear additives 0.3%-4.0%, dispersing agent 0.02%-1.0%, antirust agent 0.02%-0.8%, demulsifier 0.02%-
0.07%, defoaming agent 0.02%-0.05%, graphite dry powder 0.3%-2.0%, oil based on surplus.
Wherein, oiliness improver is liquid benzotriazole fatty acid ammonium salt；Extreme pressure anti-wear additives are di-n-butyl phosphite, thiophosphoric acid
The mixture of one or more of multiple ester amine salt, aminothio ester；Dispersing agent is Carboxylic Acid Fibre element sodium and methyl naphthalene sulfonic acid sodium

Compound；Defoaming agent is the mixed of one or both of dimethyl silicone polymer and Methylacrylate-Acrylate Copolymer
Close object；Base oil isAlkylnaphthalene AN23, oil soluble polyether OSP 32, oil soluble polyether OSP 46, oil-soluble are poly-
The mixture of one or more of ether OSP 68, polyalphaolefin PAO100, polyester J460 synthetic oil；The particle of graphite dry powder
The flaky graphite dry powder that diameter is 0.05~1.5 μm.
The self property of base oil on the final performance of product have very important influence, although wind power gear oil in plus
There are many additive (such as oiliness improver, extreme pressure anti-wear additives, dispersing agent, antirust agent, demulsifier, defoaming agents), but in use process
With the consumption of additive, the performances such as the lubrication of base oil, wear-resistant, anti-oxidant and waterproof finally influence the longevity of wind power gear oil
Life, therefore selecting high quality base oil is to produce the important link of wind power gear oil.Alkyl naphthalenes base oil selected by the present invention
In the naphthalene nucleus containing electron rich, oxygen can be absorbed, to interrupt the transmitting of oxidative chain, prevent hydrocarbon from continuing to aoxidize, therefore it has
There is stronger oxidation stability.In addition, it is different from Esters oil, without containing hydrolyzable groups in alkylnaphthalene molecule, therefore and other
Base oil is compared to it with good hydrolytic stability.In addition, alkyl naphthalenes base oil due in alkylnaphthalene naphthalene nucleus have it is higher
Electron density keep naphthalene nucleus polarity relatively strong, therefore, to polar additive dissolubility with higher and dispersibility.
The oil soluble polyether that the present invention uses for Tao Shi novel product, the product effectively improve conventional polyether base oil with
The dissolubility of other base oils.In addition, new oil-soluble polyethers remains traditional oil soluble polyether low pour point and high viscosity index (HVI)
Performance, therefore ensure that wind power gear oil within the scope of larger temperature still have good film forming, it is ensured that wind power gear
Oily steady operation in the presence of a harsh environment.Since the presence of ehter bond-O- allows to adsorb a certain amount of dissociate in oil soluble polyether
Water, hydrone are attracted in main chainof polyether molecule, water are taken away metal surface, and then avoid the generation of metal erosion, effectively
Extend service life and the drain period of wind power gear oil.
The methane sulfonic acid naphthalene sodium salt formaldehyde condensation products (molecular structure unit is as shown in formula I) that the present invention uses are to inorganic particulate
Diffusion effect it is very significant.Its diffusion effect of the longer condensation product of high condensation degree, strand is substantially better than in homologous series product
The condensation product that low-shrinkage is right, strand is short, the methane sulfonic acid naphthalene sodium salt formaldehyde condensation products that this patent selects molecular weight suitable, naphthalene core
It is mutual with the band point particle that by the intermolecular effect due to Van der Waals force of dispersion solid particle particle, forms solid particles surface
Repel, to keep the dispersion by dispersion in water.
Formula I:
Containing more in the Carboxylic Acid Fibre element sodium molecule structure (molecular structure unit is as shown in formula II) that the present invention uses
Hydroxyl polar group, the adsorbed water molecule for being more soluble in water and graphite particle surface forms hydrogen bond, to improve graphite particle
Dissolubility.The synergistic effect of above two dispersing agent makes graphite particle high degree of dispersion in water.
Formula II:
Suitable graphite particle partial size plays the role of the lubricant effect of graphite gear oil vital, and graphite particle is too
Greatly, it is difficult to which engaging friction pair gap does not have the effect for hindering two surface of friction pair frictions, thus influences greasy property.If stone
Black partial size is too small, then seriously destroys the layer structure of graphite linings, and the Mechanism of Friction Reduction of graphite linings sliding will also lose therewith, and cause
Graphite gear oil less effective.The flaky graphite particulate that the present invention selects remains complete layer structure；Gear engagement
In the process soft graphite protective layer can be formed in surface of friction pair；And lubrication uniformly can be persistently suspended under dispersing agent effect
In oil.Wind power gear oil added with graphite additive has both the antifriction of liquid gear oil, the characteristics such as wear-resistant also have solid-state stone
The lubrication of ink repairs the characteristics such as microdot is lost, extreme pressure bearing capacity is good.
The present invention provides a kind of preparation method of wind-powered electricity generation graphite gear oil, comprising steps of
S1: in a stirring kettle, distilled water, methane sulfonic acid naphthalene sodium salt formaldehyde condensation products and Carboxylic Acid Fibre element sodium are pressed 100:
(0.08~1.5): the mass ratio mixing of (0.08~1.3) is stirred well to perfect solution later, obtains dispersant solution；
The flaky graphite dry powder that grain diameter is 0.05~1.5 μm is added in dispersant solution, then passes through kneading
Machine is mediated repeatedly, the soft graphite intermediate for being greater than 2000Pas until forming viscosity, and the graphite in soft graphite intermediate
Dry powder soilless sticking phenomenon；Kneaded soft graphite intermediate is stood 1 hour later；
S2: the soft graphite intermediate after standing is placed in three-roll grinder and is ground 3~6 times, until in soft graphite
Flaky graphite dry powder dispersion in mesosome is uniform；
S3: being added other surplus stock components in constant temperature stirred tank, and the soft graphite intermediate after grinding is then added,
Being sufficiently stirred keeps soft graphite intermediate fully dispersed, obtains mixing oil product；
S4: oil product will be mixed and be transferred to the dehydrating kettle progress dehydrating operations that vacuum degree is 0.08~0.1MPa, remove miscella
Free water in product makes to mix the water content in oil product not higher than 0.03%；
S5: linear speed will be used to shear for the high-shear homogenizing machine of 30~40m/s by the mixing oil product of S4 processing, made
