Example 1
The composition of this example (total weight 500g) was prepared as follows:
first, 78 wt% of III6 base oil was heated to 60 ℃ in a blending vessel, then 15 wt% of Synative ES TMP05, 3 wt% of L135, 3 wt% of S220 and 1 wt% of H544 were added to the above blending vessel containing 78 wt% of III6 base oil, and the mixture was stirred for 2 hours at 60 ℃ and a stirring speed of 500 rmp/min.
Comparative example 1
The composition was prepared as in example 1 except that no synthetic ES TMP05, L135, S220, H544 was added.
100 weight percent of III6 base oil is added into a mixing container and stirred for 2 hours at the temperature of 60 ℃ and the stirring speed of 500-1000 rmp/min.
Comparative example 2
The composition was prepared as in example 1 except that no synthetic ES TMP05, L135, S220 was added.
99 wt% of the III6 base oil was heated to 60 ℃ in a tempering vessel, and then 1 wt% of H544 was added to the above-described tempering vessel containing 99 wt% of the III6 base oil, and stirred for 2 hours at a temperature of 60 ℃ and a stirring speed of 500 and 1000 rmp/min.
Test examples
The compositions prepared in example 1 and comparative examples 1 to 2 were subjected to the performance test, and the results are shown in Table 7.
Kinematic viscosity test according to GB/T265 method for determining kinematic viscosity and calculating kinematic viscosity of Petroleum products
The acid number test was performed according to GB/T4945 neutralization number determination of Petroleum products and lubricants (color indicator method).
TABLE 7 Performance data for a hydrogenated base oil composition having excellent solvency and good photostability
As can be seen from FIGS. 1-3 and Table 7, the group III base oil of comparative example 1 was clear and transparent, and the oil sample became noticeably cloudy after 1% of additive H544 was added to the group III base oil (comparative example 2). When the composition prepared by the invention is added into an oil sample containing group III base oil and an additive H544, the prepared oil (example 1) is still clear and transparent, which shows that the composition prepared by the invention has excellent solubility. As is clear from Table 7, the oil samples of comparative examples 1 and 2 showed large changes in viscosity and acid value after 1 month of sun exposure, and the oil sample of example 1 showed small changes in viscosity and acid value after sun exposure. Hydrocarbon lubricating oils undergo oxidation reactions under sunlight or heating conditions, which leads to the decomposition of the lubricating oil chain and the formation of oxidation products. Oxidation products dissolved and dispersed in the oil cause an increase in the acid number and viscosity of the oil and insoluble deposits precipitate from the oil as sludge. Therefore, the composition prepared by the invention has good light stability.
The tests prove that: the composition prepared by the invention not only has excellent solubility, but also has good light stability.
The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, however, the present invention is not limited to the specific details of the above embodiments, and various simple modifications can be made to the technical solution of the present invention within the technical idea of the present invention, and these simple modifications are within the protective scope of the present invention.
It should be noted that the various technical features described in the above embodiments can be combined in any suitable manner without contradiction, and the invention is not described in any way for the possible combinations in order to avoid unnecessary repetition.
In addition, any combination of the various embodiments of the present invention is also possible, and the same should be considered as the disclosure of the present invention as long as it does not depart from the spirit of the present invention.
