Embodiment 1
[0033] Weigh 191.14g (1mol) of aminotriacetic acid, 156.23g (1.5mol) of neopentyl glycol, and 8g of phosphotungstic acid and place them in the reaction kettle, stir and heat to 150°C, fully react for 5 hours, and drain twice under reduced pressure during the reaction. , adding 65.16g (0.5mol) of isooctyl alcohol and raising the temperature to 180° C. After the reaction is completed for 3 hours, the water is decompressed to remove water; it is an anti-wear grease composition.
[0034] The above-mentioned antiwear grease composition can be used as a grease as it is.
Embodiment 2
[0036] Weigh 191.14 g (1 mol) of aminotriacetic acid, 145.81 g (1.4 mol) of neopentyl glycol, and 6 g of phosphotungstic acid and place them in the reaction kettle, stir and heat to 160 ° C, fully react for 4 hours, and drain the water under reduced pressure once during the reaction. , adding 158.28 g (1 mol) of isodecanol and heating up to 200° C. After the reaction is completed for 2 hours, the water is decompressed to remove water; it is an anti-wear grease composition.
[0037] Weigh 400 g of the anti-wear grease composition, 500 g of poly-2,5-furandicarboxylate neopentyl glycol, and 100 g of molybdenum disulfide at 100°C for 1.5 hours, and place them in a homogenizer for 1 hour of homogenization treatment. It is an anti-wear grease.
[0038] The preparation method of above-mentioned poly-2,5-furandicarboxylate neopentyl glycol:
[0039] 468.27 g (3 mol) of 2,5-furandicarboxylic acid, 312.45 g (3 mol) of neopentyl glycol, and 3.6 g of phosphotungstic acid were added to th...
Embodiment 3
[0043] 191.14g (1mol) of aminotriacetic acid, 104.15g (1mol) of neopentyl glycol, 6g of phosphotungstic acid were weighed and placed in the reactor, heated to 160°C with stirring, fully reacted for 4 hours, and the reaction process was decompressed and drained once, 268.69 g (0.9 mol) of isoeicosanol was added and the temperature was raised to 200° C., and after the reaction was completed for 2 hours, the water was decompressed to remove water; it was an anti-wear grease composition.
[0044] After weighing 500 g of anti-wear grease composition, 400 g of poly-2,5-furandicarboxylate neopentyl glycol, 95 g of molybdenum disulfide, 2 g of IrganoxL57 antioxidant, and 3 g of IrganoxL135 antioxidant at 100°C for 1.5 hours, Placed in the homogenizing equipment for 1 hour, it is an anti-wear grease.
[0045] The preparation method of above-mentioned poly-2,5-furandicarboxylate neopentyl glycol:
[0046] 312.18g (2mol) of 2,5-furandicarboxylic acid, 229.13g (2.2mol) of neopentyl glyco...
