Test example:
the strong oil film protective motor oils prepared in examples 1 to 4 above were subjected to a number of tests, the test items and the results are shown in the following table:
from the above table:
in terms of appearance, the oil film protection engine oils of examples one to four are all in a brown yellow transparent state, which indicates that the oil film protection engine oils have no abnormal change in appearance and accord with normal oil characteristics.
In terms of density, the densities of examples one to four were all between 0.8655g/cm and 0.8673g/cm , with similar numerical ranges indicating similar compositions and ratios.
In terms of kinematic viscosity, the kinematic viscosities of examples one to four varied within similar ranges at 40℃and 100 ℃. This indicates that these motor oils have suitable flow properties at different temperatures and provide good lubrication when the engine is running.
In terms of viscosity index, the viscosity indexes of embodiments one to four are 120, 131 and 131, respectively. The values show that the oil products have better viscosity and temperature stability, can keep relatively stable viscosity under different temperature conditions, and meet the requirement of an engine on the viscosity of lubricating oil.
The flash points for examples one to four were 220℃in terms of flash point and pour point, and the pour points were-30 ℃. The data show that the engine oil has good combustion performance and low-temperature flow performance and can normally operate under different working conditions.
In terms of low temperature dynamic viscosity, the low temperature dynamic viscosity of examples one to four was different at-20 ℃. The low-temperature dynamic viscosity of example three was the lowest, 3317 mPas, while that of example two was the highest, 4348 mPas. These data indicate that example two has better cold start and flow properties.
In terms of the dynamic friction index DFI, the dynamic friction indexes of examples one to four were all around 1.0. This means that they can provide adequate friction protection, reducing wear and friction between metal parts.
The static friction index SFI indicates the friction performance between the friction plate and the steel. According to the data in the table, the static friction indexes SFI of examples one to four were all between 1.1 and 1.2, which indicates that they have similar performance in terms of friction performance.
The stop time index STI also reflects the friction performance. The stop time indices STI of examples one to four are each between 1.0 and 1.3, similar to the dynamic friction index, indicating that they are capable of providing adequate friction protection in the stopped state.
