Experimental subject is the mixture that obtains in embodiment 4, and the experimental standard of ball disk experiment is ASTM G99, the experiment of ball disk
Schematic diagram is shown in Fig. 5.In the experiment of ball disk, lubricating oil is immersed on the surface of ball and disk sample, and test parameter is as shown in table 1.
Table 1：Ball disk experiment test parameter
Fig. 6 is 500 × 10 for the mass fraction concentration of oil-soluble grafting/pectination polyamine surfactant-4Under the conditions of, averagely
Coefficient of friction<μ>With fluorographite (CF)nThe functional relationship of the mass fraction in base oil.It will be evident that with fluorographite
(CF)nThe increase of the mass fraction in base oil,<μ>It is gradually lowered.As seen from Figure 6,<μ>Minimum be about 0.05.Fig. 6
In, average friction coefficient<μ>It is the time average (computational methods see below formula) of coefficient of friction, optimal test period is 900s.
Δ μ is calculated by least absolute deviation method：
Fig. 7 is shown containing fluorographite (CF)nTwo groups of samples of base oil dispersion liquid and base oil coefficientoffrictionμ at any time
Between the functional relationship that changes.Wherein containing fluorographite base oil dispersion liquid in fluorographite mass fraction concentration be 50 ×
10-4, the mass fraction concentration of oil-soluble grafting/pectination polyamine surfactant is 500 × 10-4.Based on the examination in Fig. 6 and Fig. 7
Test result, hence it is evident that it can be seen that the fluorographite of fine dispersion can be effective for lubricating oil or grease additive.
