Embodiment 1
[0024] A vegetable oil-based high-temperature-resistant lubricating oil, which is made of the following raw materials in parts by weight: 20 parts of corn oil, 12 parts of castor oil, 10 parts of hydroxyl-terminated dimethyl diphenyl polysiloxane, and 3 parts of polyvinyl alcohol , 3 parts of ethanolamine, 4 parts of polyethylene glycol monomethyl ether, 1 part of ferrocene, 1 part of preservative, 3 parts of composite graphite powder, and 2 parts of modified nano-silica.
[0025] The composite graphite powder is prepared by the following method: slice the paraffin wax, place it in an electric drying oven, raise the temperature to fully melt the paraffin wax, keep it warm, then add graphite powder of equal quality, stir evenly with the graphite powder, After standing and cooling at room temperature, pulverize and pass through a 200-mesh sieve to obtain paraffin-modified composite graphite powder.
[0026] The modified nano silicon dioxide is prepared by the following method: ...
Embodiment 2
[0037]A vegetable oil-based high-temperature-resistant lubricating oil, which is made of the following raw materials in parts by weight: 30 parts of corn oil, 15 parts of castor oil, 13 parts of hydroxyl-terminated dimethyl diphenyl polysiloxane, and 4 parts of polyvinyl alcohol , 5 parts of ethanolamine, 6 parts of polyethylene glycol monomethyl ether, 2 parts of ferrocene, 2 parts of preservative, 4 parts of composite graphite powder, and 3 parts of modified nano-silica.
[0038] This example is the same as Example 1 except that the formulation dosage is different from Example 1. The preparation method of the vegetable oil-based high temperature resistant lubricating oil in this example is also the same as Example 1.
Embodiment 3
[0040] A vegetable oil-based high-temperature-resistant lubricating oil, which is made of the following raw materials in parts by weight: 40 parts of corn oil, 18 parts of castor oil, 15 parts of hydroxyl-terminated dimethyl diphenyl polysiloxane, and 5 parts of polyvinyl alcohol , 7 parts of ethanolamine, 8 parts of polyethylene glycol monomethyl ether, 3 parts of ferrocene, 3 parts of preservative, 5 parts of composite graphite powder, and 5 parts of modified nano-silica.
[0041] This example is the same as Example 1 except that the formulation dosage is different from Example 1. The preparation method of the vegetable oil-based high temperature resistant lubricating oil in this example is also the same as Example 1.
