S1 containing all-fluoroalkyl compound is remained on face, to form skin covering of the surface.As shown in Figure 1, as S1 containing all-fluoroalkyl compound,
For example, having perfluoroalkyl Rf and lipophilic group L.Lipophilic group L is higher than compatibility of the perfluoroalkyl Rf to oil.Lipophilic group L band is just
Electric δ+, the negatively charged δ-of perfluoroalkyl Rf.This is because perfluoroalkyl Rf contains fluorine element, electronegativity polarizes caused to δ-.
Since perfluoroalkyl Rf is smaller than lipophilic group L to the compatibility of lubricating grease G, as shown in Figure 1, perfluoroalkyl Rf holds
Easily arranged from lubricating grease surface towards foreign side.At this point, at least part containing all-fluoroalkyl compound can also bury to lubricating grease G
It is interior.In addition, Fluoropolyether compound shown in Fig. 3 is also same.
Fig. 2 indicates the schematic diagram of the movement containing all-fluoroalkyl compound when being mixed into foreign matter.It is mixed that Fig. 2 illustrates foreign matter C
Enter to the pattern in lubricating grease G.As foreign matter C, for example, with SiO2For main component, the Surface Polarization of foreign matter C is δ-.Therefore,
As shown in Fig. 2, being adsorbed with lipophilic group (δ+) L in a manner of charge neutrality on foreign matter C.Perfluoroalkyl Rf becomes in foreign matter as a result,
The state of outside (opposite side of absorption side) arrangement of C.It is arranged with the parent of the foreign matter C and lubricating grease G of perfluoroalkyl Rf on the outside
It is small with property.As a result, foreign matter C becomes the state being suspended in lubricating grease G, and generates and shifted towards lubricating grease G surface direction
Effect (shown in Fig. 2 arrow).Foreign matter C is placed in the state that can be removed to the outside of lubricating grease G easily as a result,.Moreover,
The foreign matter C being removed from lubricating grease G becomes the shape that outer peripheral surface is covered by the perfluoroalkyl Rf low with the compatibility of lubricating grease G
State, therefore be not easy to be mixed into lubricating grease G (referring to the "×" symbol of Fig. 2).
Next, to being coated on the surface of lubricating grease at the solvent type lubricant containing Fluoropolyether compound
The mechanism of foreign matter removal in the state of reason agent is illustrated.
Fig. 3 is the schematic diagram for indicating the state for the Fluoropolyether compound being coated on lubricating grease surface.As shown in figure 3,
When lubricant inorganic agent is applied to the surface of lubricating grease G, disappear after solvent evaporation, and then on the surface of lubricating grease G
On remained Fluoropolyether compound S2, to form skin covering of the surface.
As shown in figure 3, due to remain in lubricating grease G surface on Fluoropolyether compound S2 because the electricity of fluorine atom F is negative
Property highest, thus the positively charged δ of negatively charged δ-, functional group R+.
Since fluorine atom F is smaller than functional group R to the compatibility of lubricating grease G, as shown in figure 3, fluorine atom F is easy from profit
Consistent lubricant surface is arranged towards foreign side.
Fig. 4 indicates the schematic diagram of the movement of Fluoropolyether compound when being mixed into foreign matter.Fig. 4 illustrates foreign matter C and is mixed into
To the pattern in lubricating grease G.As foreign matter C, for example, with SiO2For main component, the Surface Polarization of foreign matter C is δ-.Therefore, such as
Shown in Fig. 4, on foreign matter C, functional group (δ+) R is adsorbed in a manner of charge neutrality.Fluorine atom F becomes foreign matter C's as a result,
The state of outside (opposite side of absorption side) arrangement.Foreign matter C and the compatibility of lubricating grease G for being arranged with fluorine atom F on the outside are small.
As a result, foreign matter C becomes the state being suspended in lubricating grease G, and generate the effect shifted towards lubricating grease G surface direction
(shown in the arrow of Fig. 4).Foreign matter C is placed in the state that can be removed to the outside of lubricating grease G easily as a result,.Moreover, from profit
The foreign matter C that consistent lubricant G is removed becomes the state that outer peripheral surface is covered by the perfluoroalkyl Rf low with the compatibility of lubricating grease G, because
This is not easy to be mixed into lubricating grease G (referring to the "×" symbol of Fig. 4).
Above-mentioned foreign matter removal effect is for example in significantly moving in component each other, the cunning as track and sliding block
In the case where dynamic relationship, especially effectively.Even, can also be by using the lubrication of present embodiment that is, the lubricating grease of semisolid
Agent surface treating agent easily makes the foreign matter (referring to Fig. 2) for passing through sliding liquidation and being covered by perfluoroalkyl, by fluorine original
The foreign matter (referring to Fig. 4) of son covering, it is promptly mobile towards the surface of lubricating grease, and be discharged to outside.Further, since alkane containing perfluor
Based compound, Fluoropolyether compound itself also can form envelope on the surface with sliding face contact, therefore can be more efficient
Ground assigns foreign matter and removes lubricating composition lubricity.
In addition, being hereinbefore illustrated using the mechanism that such as under type removes foreign matter, that is, be coated in lubricating grease G
Surface on lubricant inorganic agent solvent evaporation, to formed on the surface containing all-fluoroalkyl compound and fluorine-containing poly-
The mode of the skin covering of the surface of ether compound, and the oil film O of Fig. 5 is also to promote foreign matter to remove according to same mechanism.
