Example Embodiment
[0028] Example 1
[0029] Preparation of nano-silica grease of the present invention
[0030] A certain amount of silicone oil was weighed, heated to 150°C, and kept at a constant temperature for 5min. At this temperature, add the modifier, the content of which is 20% by mass of the silica, and stir until the modifier is uniformly dispersed in the base oil. Stirring was continued to raise the temperature to 157°C. Constant temperature for 5min. Stop heating, add nano-silica, and stir well. Grind twice with a three-roll mill to form grease.
Example Embodiment
[0031] Example 2
[0032] Preparation of nano-silica grease of the present invention
[0033] A certain amount of silicone oil was weighed, heated to 132°C, and kept at a constant temperature for 5min. At this temperature, add the modifier, the mass of which is 10% of the mass of silica, and stir until the modifier is uniformly dispersed in the base oil. Stirring was continued to raise the temperature to 140°C. Constant temperature for 5min. Stop heating, add nano-silica, and stir well. Grind twice with a three-roll mill to form grease.

[0034] Example 3
[0035] Preparation of nano-silica grease of the present invention
[0036] A certain amount of silicone oil was weighed, heated to 120°C, and kept at a constant temperature for 5min. At this temperature, add the modifier, the mass of which is 5% of the mass of silica, and stir until the modifier is uniformly dispersed in the base oil. Stirring was continued to raise the temperature to 130°C. Constant temperature for 5min. Stop heating, add nano-silica, and stir well. Grind twice with a three-roll mill to form grease.
