Example Embodiment
[0033] Example 1:
[0034] Put 15 grams of 12-hydroxystearic acid, 15 grams of stearic acid and 400 grams of paraffin-based mineral base oil into the reaction kettle, raise the temperature to 80°C, add 4.5 grams of aqueous solution of lithium hydroxide, and the amount of water added is 25 Grams. Warm up to 90℃ to start timing saponification, 1.5 hours after saponification, heat up after the saponification is over, use 300 grams of paraffin-based mineral base oil to cool in the reactor after heating to 210℃, when the cooling temperature is 145℃, continue to add 180 grams of ester Cooling the base oil (pentaerythritol ester), add 10 grams of calcium dinonyl sulfonate to 98℃, add 20 grams of solid anti-wear additive (tin metal powder) when the temperature drops to 79℃, wait until the temperature drops to 59℃ The finished product will be produced after three passes through the three-roll mill. The properties of the grease prepared by the process formula of the present invention are...

[0046] Example 2:
[0047] Combine 5 grams of 12-hydroxystearic acid and 35 grams of C 18 The fatty acid and 400 grams of paraffin mineral base oil were put into the reaction kettle, the temperature was raised to 85°C, and 6.5 grams of lithium hydroxide solution was added, and the amount of water added was 35 grams. Warm up to 95℃ to start timing saponification, 1 hour after saponification, heat up after the saponification is over, use 200 grams of naphthenic mineral base oil to cool in the reactor after heating to 210℃, when the cooling temperature is 140℃, continue to add 200 grams Ester base oil (trimethylolpropane ester) is cooled, and 5 grams of barium dinonyl sulfonate is added to the temperature to 100°C. When the temperature drops to 76°C, 25 grams of solid antiwear additive (borate) is added. After the temperature drops to 60℃, the finished product will be produced after three times of oil rolling on the three-roll mill. The properties of the grease prepared by the proc...

[0059] Example 3:
[0060] Put 30 grams of C 16 Hydroxy fatty acids and 10 g of C 20 The fatty acid and 400 grams of intermediate base mineral base oil were put into the reactor, the temperature was raised to 83°C, and 5.8 grams of lithium hydroxide solution was added, and the amount of water added was 30 grams. Warm up to 100℃ to start timing saponification, 2 hours after saponification, heat up after the saponification is over, use 200g of naphthenic mineral base oil to cool in the reactor after heating up to 210℃, when the cooling temperature is 150℃, continue to add 200g The ester base oil (dioctyl sebacate) is cooled, and 6 grams of zinc naphthenate is added to the temperature to 100°C. When the temperature drops to 76°C, 24 grams of solid antiwear additive (zinc oxide) is added. The finished product will be produced after three passes through the three-roll mill at 56°C. The properties of the grease prepared by the process formula of the present invention are listed in the...
