Specific implementation mode
A kind of lubricant composition of the present invention, including thickening agent, further include the basis containing nonpolar alkyl naphthalenes oil Oil and the additive with the compound packet of antifriction antiwear;Compound antifriction antiwear includes that extreme pressure anti-wear additives, esters anti-friction agent and oil are molten Property polyethers.Base oil, thickening agent and additive are based on following parts by weight:
100 parts of base oil
6-16 parts of thickening agent
2-35 parts of additive
The present invention is added oil soluble polyether as additive, and dosage is smaller;And by oil soluble polyether and nonpolar alkane Synergistic effect between base naphthalenes oil allow lubricant composition have extremely strong dissolubility, it is compound to antifriction antiwear packet and other add Add agent fully to dissolve, ensures the lubricant composition of the present invention in technique at 40 DEG C, kinematic viscosity 12mm2/s-9000mm2/ S, forms lubricating film between the parts surface of relative motion at this time, and the OK range of kinematic viscosity makes lubricating film both will not be because It is excessively thin so that electric tool is from operating, will not be blocked up because of oil film, cold-starting encounters difficulties, and the generation of oil film will not be with Additive generates competitive Adsorption so that metal friction subtabulation can be farthest adsorbed in by playing the additive of antiwear and antifriction Face, the lubricating film reduce the generation overheated between friction, abrasion and moving component so that the antiwear and antifriction of lubricant composition Significant effect is promoted, and the presence of lubricating film reduces the temperature of cylinder surfaces, and then reduces the formation of coking carbon deposit.With this Meanwhile the friction coefficient of polar oil soluble polyether itself is extremely low, has effects that antifriction;One as the compound packet of antifriction antiwear It is mutually cooperateed between part, oil soluble polyether and extreme pressure anti-wear additives and esters anti-friction agent, enables lubricating grease that there is the wear-resistant of brilliance Friction reducing effect significantly extends lubricant composition so that lubricating grease will not be aoxidized because of the high temperature of frictional heat Service life.

Friction coefficient is relatively low in each embodiment of first test group, and sintering load is high, function admirable;Second test group Each embodiment nonpolarity PAO synthetic oils are replaced using nonpolar mineral oil, because nonpolar mineral oil is closed relative to nonpolar PAO Can be relatively low at oil lubricity, therefore friction coefficient is higher;Lubricant composition in each embodiment of third test group is not added Polarity Esters oil causes the lubricity of lubricating grease inadequate, and opposite first test group, friction coefficient is improved to some extent.But It is that whether nonpolar alkyl naphthalenes oil is added in the first test group, the second test group or third test group in base oil, It can be seen by the content of table 1, table 2, table 3, compared with table 4, the lubricant compositions of three test groups all has lower Friction coefficient, sintering load are also relatively high.
Cylinder is added to foregoing grease composition and carries out ultimate life test:
A, test condition:Cylinder continuous operation records cylinder continuous operation hourage, and dismantles cylinder and watch cylinder inner wall Coking carbon distribution situation.
B, test object selects:
Three kinds of nonpolarity PAO synthetic oils, nonpolar alkyl naphthalenes oil and polarity Esters oil mixing are selected in first test group Made of base oil, because of the equal higher price of this three classes oil, therefore choose the best lubrication prepared according to embodiment 1 of economy Oil/fat composition injects electric tool cylinder and carries out life test.
Selected in second test group nonpolar mineral oil, the three kinds of oil mixing of nonpolar alkyl naphthalenes oil and polarity Esters oil and At base oil because mineral base oil is cheap, high temperature performance, antioxygenic property respectively with nonpolar PAO synthetic oils, The corresponding performance of polarity Esters oil greatly differs from each other, in order to obtain the lubricant composition of optimum performance, therefore selects performance The lubricant composition injection electric tool cylinder of best embodiment 4 carries out life test.
The base oil for selecting nonpolarity PAO synthetic oils, nonpolar alkyl naphthalenes two kinds of oil of oil to mix in third test group, because For the equal higher price of two classes oil, therefore it is electronic to choose the best lubricant composition injection prepared according to embodiment 9 of economy Tool cylinder carries out life test.
C, test result is as shown in table 5:
5 life test of table compares
To sum up, in the first test group, lubricant composition friction coefficient is minimum, the service life longest in cylinder, and gas Spatter property is good in cylinder;Without nonpolar alkyl naphthalenes oil in comparative example 1, halve compared to the first test group service life.
In second test group, lubricant composition friction coefficient is slightly higher, but high due to accounting for more nonpolar mineral oil Warm antioxygenic property is poor, and after cylinder life test, cylinder inner wall carbon deposit is quite serious, and run time is shorter;In comparative example 2 not The oil of naphthalenes containing nonpolar alkyl, service life reduce 2 times than the second test group.
In third test group, lubricant composition friction coefficient is relatively low, and service life is longer in cylinder, and in cylinder Spatter property is good;In comparative example 3 about half is reduced without nonpolar alkyl naphthalenes oil, service life.
It is fed back according to user, lubricant composition of the invention has good anti-compared to market common lubricant fat Antifriction performance is ground, and 2-20 times is dramatically increased using the working life of exhaust hood.
Schematically the present invention and embodiments thereof are described above, description is not limiting, so, if Those skilled in the art are enlightened by it, without departing from the spirit of the invention, are not inventively designed Go out technical solution similar with the technical solution and embodiment, is within the scope of protection of the invention.
