Embodiment 1
[0038] Weigh 1000g of eleostearic acid, 600g of stearyl alcohol, and 50g of melamine and place them in the reaction kettle, slowly add 50g of phosphorus pentasulfide while stirring, after adding phosphorus pentasulfide, fully stir and react for 3 hours at a temperature of 120°C, and cool down to below 100°C When the temperature is lower than 100°C, add 100g of isopropanolamine, mix and stir, and then add it to the homogenization equipment for homogenization. Treat for 1 hour; that is, an organic molybdenum grease composition.
[0039] The above-mentioned organic molybdenum grease composition can be used as a grease as it is.
[0040] The organo-molybdenum grease composition prepared above was subjected to a roller stability test according to SH / T0122:
[0041] project Before rolling After 2 hours of rolling experimental method Dropping point °C 251 251 GB / T4929 Pressure Oil % 0.2 0.2 GB / T392 Penetration 0.1mm 237 237 GB / T269
Embodiment 2
[0043] Weigh 1000 g of eleostearic acid, 600 g of stearyl alcohol, and 30 g of melamine and place them in the reactor, slowly add 30 g of phosphorus pentasulfide while stirring, and after adding phosphorus pentasulfide, fully stir and react for 2 hours at a temperature of 130 ° C, and cool down to below 100 ° C 150g of ammonium phosphomolybdate was added, heated to 150°C, fully reacted for 3 hours, decompressed to remove moisture and ammonia gas; cooled to below 100°C, added with 80g of isopropanolamine, mixed and stirred, and then added to a homogenizer for homogenization. Treat for 1 hour; that is, an organic molybdenum grease composition.
[0044] Weigh 600 g of the organic molybdenum grease composition prepared above, 300 g of castor oil polymaleate, and 100 g of molybdenum disulfide, and heat and stir to about 100 ° C. About an hour, it is an organic molybdenum high temperature grease.
