Embodiment 1
[0038] Weigh 1000g of laccarnation 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 at 120°C for 3 hours, and cool down to below 100°C. Add 200g of ammonium phosphomolybdate, heat to 150°C, fully react for 3 hours, remove moisture and ammonia under reduced pressure; cool down to below 100°C, add 100g of isopropanolamine for mixing and stirring, then add to homogenization equipment for homogenization Treat for 1 hour; it is an organic molybdenum grease composition.
[0039] The above organic molybdenum grease composition can be directly used as grease.
[0040] The organic molybdenum grease composition prepared above was subjected to the roller stability test according to SH / T0122:

Embodiment 2
[0043] Weigh 1000g of laccarnation acid, 600g of stearyl alcohol, and 30g of melamine and place them in the reaction kettle. Slowly add 30g of phosphorus pentasulfide while stirring. After adding phosphorus pentasulfide, fully stir the reaction at 130°C for 2 hours, and cool down to below 100°C. Add 150g of ammonium phosphomolybdate, heat to 150°C, fully react for 3 hours, remove moisture and ammonia under reduced pressure; cool down to below 100°C, add 80g of isopropanolamine for mixing and stirring, then add to homogenization equipment for homogenization Treat for 1 hour; it is an organic molybdenum grease composition.
[0044] Weigh 600g of the above-prepared organic molybdenum grease composition, 300g of polycastor oil maleate, and 100g of molybdenum disulfide, heat and stir to about 100°C, and after stirring for 1 hour, place them in a homogeneous equipment for homogeneous treatment for 1 Hours or so, that is a kind of organic molybdenum high temperature grease.
