Embodiment 1～16, comparative example 1～3
Use above-mentioned composition and material, prepared the lubricating oil composition of embodiment 1～16 and comparative example 1～3 with the formation shown in table 1～table 4.
Test
Thereby the lubricating oil composition of embodiment 1～16 and comparative example 1～3 is carried out following test observe their performance.
Frictional coefficient
Make Masuda (field once) the pendulum type oiliness test measuring apparatus frictional coefficient that machine Co., Ltd. makes with refreshing steel.In this test, test oil is fed to the friction portion of the fulcrum of pendulum, make the pendulum vibration and obtain frictional coefficient by the decay of vibration.
The assessment of using following standard to test:
Frictional coefficient is no more than 0.135:
(excellence)
Frictional coefficient is 0.136～0.145:
O (well)
Frictional coefficient is more than or equal to 0.146:
X (unacceptable)
Antirust test
According to JIS K2510, get the test oil of 300ml and be placed in the container that is installed in the thermostatic bath.Stir with 1000 rpms speed.When temperature reaches 60 ℃, insert iron specimen in this oil and add the synthetic sea water of 30ml again.Temperature is remained on 60 ℃, continue to stir 48 hours.Subsequently sample is taken out the also appearance of any rust of visual inspection.
Comprise the antirust test of formic acid
According to JIS K2510, get the test oil of 300ml and be placed in the container that is installed in the thermostatic bath.Stir with 1000 rpms speed.When temperature reaches 60 ℃, insert iron specimen in this oil and the synthetic sea water that adds 30ml again adds the formic acid of 0.1ml.Temperature is remained on 60 ℃, continue to stir 24 hours.Subsequently sample is taken out the also appearance of any rust of visual inspection.
This antirust test that comprises formic acid uses the antirust test of synthetic sea water to have more exacting terms than above-mentioned, and embodiment 11～16 is carried out.
Test result
The result of these tests shows in table 1～table 4.
Can know from test result shown table 1 and table 2 and to find out, use the lubricating oil composition shown in the embodiment 1～8 of the aspartic acid derivate (additive A) that joins simultaneously in the highly refined base oil (base oil 1～base oil 5) and polyol ester (additive B), all had excellence
Lower frictional coefficient, and their in antirust test, mark qualified (non-corrosives in synthetic sea water).In addition, as can be seen, the lubricating oil composition that uses aspartic acid derivate (additive A) and polyol ester (additive B) simultaneously and be added with fatty amine (additive D) also has excellence in the situation of embodiment 9 and 10
Lower frictional coefficient, and their in antirust test, mark qualified (non-corrosives in synthetic sea water).Therefore can confirm that the lubricating oil composition of embodiment 1～10 causes the reduction of frictional coefficient and the improvement of rust inhibiting property.
Can know from test result shown table 3 and to find out, use the lubricating oil composition shown in the embodiment 11 of aspartic acid derivate (additive A), polyol ester (additive B) and epoxy compounds (addition of C) simultaneously, have excellence
Lower frictional coefficient, and it all marks in two antirust tests qualified (adding in the harsher situation of formic acid all non-corrosives in synthetic sea water or at synthetic sea water), so obtained excellent result significantly.And, use the lubricating oil composition of the embodiment 12～16 that joins aspartic acid derivate (additive A), polyol ester (additive B), epoxy compounds (addition of C) and fatty amine (additive D) in the base oil 1～4 simultaneously, also have excellence
Lower frictional coefficient, and in two antirust tests, all mark qualified (in synthetic sea water or at synthetic sea water, adding in the harsher situation of formic acid all non-corrosives), reduce effect and rust inhibiting property so obtained excellent frictional coefficient significantly.
On the other hand, can find out, in the situation of the comparative example 1 that only has base oil 1, all get rusty in frictional coefficient unacceptably high (X) and the synthetic sea water in antirust test neutralizes the antirust test that comprises formic acid from the test result of table 4.Add in the situation of comparative example 2 of aspartic acid derivate (additive A) therein to base oil 1, frictional coefficient unacceptably high (X), though and it has passed through antirust test, it is not by comprising the antirust test (getting rusty) of formic acid.And, adding in the situation of comparative example 3 of polyol ester (additive B) therein to base oil 1, frictional coefficient is qualified with good (O) at least, but in antirust test with comprise in the antirust test of formic acid and all get rusty.Therefore, in the situation of comparative example 1～3, they are being used as the improvement of not observing rubbing characteristics or rust inhibiting property in the application of lubricating oil composition.
