Embodiment 1
[0025] The long-life anti-seize grease composition has the following components and mass percentages:
[0026] (1) No. 2 complex calcium sulfonate base grease 92.4%;
[0027] (2) T551 0.5%;
[0028] (3) Calcium Dinonylnaphthalene Sulfonate 3.0%
[0029] (4) Molybdenum disulfide powder 0.6%;
[0030] (5) Titanium dioxide 2.7%;
[0031] (6) HSD 0.8%.
[0032] First, 924.0 g of No. 2 composite calcium sulfonate base grease (working penetration 242, unit 0.1 mm) was put into the kettle, and stirred to raise the temperature. When the temperature reaches 120°C, 5.0g of T551, 3.0g of calcium dinonylnaphthalenesulfonate, 6.0g of molybdenum disulfide powder (fineness<5μm), 2.7g of titanium dioxide (320 mesh sieve residue<0.1%), and HSD 8.0g. Stir for 21min, then get out of the kettle. Grind it three times with a three-roll machine to get the finished product.
Embodiment 2
[0034] The long-life anti-seize grease composition has the following components and mass percentages:
[0035] (1) No. 1 complex calcium sulfonate base grease 91.2%;
[0036] (2) T561 0.6%;
[0037] (3) Zinc dinonylnaphthalene sulfonate 2.8%;
[0038] (4) Tungsten disulfide 1.3%;
[0039] (5) Ceramic powder 3.4%;
[0040] (6) Ceramic powder 0.7%.
[0041] First, put 912g of No. 1 composite calcium sulfonate base grease (working penetration 331, unit 0.1mm) into the kettle, stir and heat up. When the temperature reaches 118°C, 16.0g of T56, 2.8g of zinc dinonylnaphthalenesulfonate, 1.3g of tungsten disulfide (fineness<5μm), 3.4g of ceramic micropowder (residue of 320 mesh sieve<0.1%) and ceramic Micropowder 7.0g. Stir for another 18min, then get out of the kettle. Grind it three times with a three-roll machine to get the finished product.
Embodiment 3
[0043] The long-life anti-seize grease composition has the following components and mass percentages:
[0044] (1) No. 2 complex calcium sulfonate base grease 82.9%;
[0045] (2) T551 1.0%;
[0046] (3) Calcium Dinonylnaphthalene Sulfonate 4.8%
[0047] (4) Molybdenum disulfide 3.2%;
[0048] (5) Ceramic powder 4.5%;
[0049] (6) HSD 3.6%.
[0050] First, 829.0 g of No. 2 composite calcium sulfonate base grease (working penetration 242, unit 0.1 mm) was put into the kettle, and stirred to raise the temperature. When the temperature reaches 95°C, 10.0g of T551, 48.0g of calcium dinonylnaphthalenesulfonate, 32.0g of molybdenum disulfide (fineness<10μm), 45g of ceramic micropowder (320 mesh sieve residue<0.3%) and HSD 36.0 are sequentially added. g. Stir for another 30min, then get out of the kettle. Grind it three times with a three-roll machine to get the finished product.
