Example Embodiment
[0022] Example one
[0023] In this embodiment, the raw materials are prepared as follows:
[0024] Step 1. Put the viscosity of 120mm at 40℃ into the fat making kettle with heating and stirring function 2 / s,
[0025] 1618g of base oil 500SN and 321.6g of 12-hydroxystearic acid are mixed and stirred and heated to 85°C to dissolve all the 12-hydroxystearic acid;
[0026] Step 2: Add a mixture of 24.9g calcium hydroxide and 23.7g monohydrate lithium hydroxide dissolved with 3 times the amount of water, saponify at 85°C for 40min, continue to heat up to 95°C, add 86.7g sebacic acid, Then add 240ml of an aqueous solution containing 47.4g of lithium hydroxide monohydrate to react for 60 minutes, and then raise the temperature to 215°C for high-temperature refining;
[0027] Step 3. Add 659g base oil 500SN, cool to 175°C and keep it for 15min. When the temperature drops to 85°C, add 15g diphenylamine, 45g thion butyl octyl zinc salt, 45g sulfide isobutylene, and 45g phosphoric acid. Tr...
