Embodiment 1

[0026] Mix 110 grams of high alkalinity calcium sulfonate and 170 grams of 150BS base oil evenly, add 10 grams of acetic acid diluted with 3 times of water, and 5 grams of boric acid diluted with 4 times of water, heat to 80 ° C, keep warm for 30 minutes, the material changes After thickening, heat up to 120°C for dehydration for 30 minutes. Add 35 grams of stearic acid and 15 grams of benzoic acid and stir evenly, add 85 grams of 500SN, cool to 100° C., add 25 grams of trimer aluminum (purity is 50%), and react for 45 minutes. Raise the temperature to 190°C, keep it warm for 10 minutes, add 85 grams of 150BS, cool down to 120°C, and use a three-roll mill to grind it into fat.

Embodiment 2

[0028] Mix 160 grams of high alkali value calcium sulfonate and 150 grams of PAO20 (synthetic hydrocarbon oil) base oil evenly, add 10 grams of acetic acid diluted with 3 times of water, 5 grams of boric acid diluted with 4 times of water, heat to 80 ° C, and keep warm After 30 minutes, the material thickened and then heated to 120°C for dehydration for 30 minutes. Add 28 grams of stearic acid and 12 grams of benzoic acid and stir evenly, add 75 grams of PAO20 (synthetic hydrocarbon oil), cool down to 100° C., add 20 grams of trimer aluminum (purity is 50%), and react for 45 minutes. Raise the temperature to 190°C, keep it warm for 10 minutes, add 75 grams of PAO20 (synthetic hydrocarbon oil), cool down to 120°C, and use a three-roll mill to grind it into fat.

Embodiment 3

[0030] Mix 210 grams of high alkalinity calcium sulfonate and 130 grams of 500SN base oil evenly, add 10 grams of acetic acid diluted with 3 times of water, 5 grams of boric acid diluted with 4 times of water, heat to 80 ° C, keep warm for 30 minutes, the material turns After thickening, heat up to 120 degrees for dehydration for 30 minutes. Add 21 grams of stearic acid and 9 grams of benzoic acid and stir evenly, add 65 grams of 500SN, cool down to 100° C., add 15 grams of trimer aluminum (purity is 50%), and react for 45 minutes. Raise the temperature to 190°C, keep it warm for 10 minutes, add 65 grams of 150BS, cool down to 120°C, and use a three-roll mill to grind it into fat.

Abstract

The composite aluminum base grease is prepared with high alkalinity calcium sulfonate 20-50 weight portions, thickener of composite aluminum soap 5-15 weight portions and base oil 35-75 weight portions. The preparation process includes the steps of converting the high alkalinity calcium sulfonate from Netwtonian substance into non-Netwtonian substance; adding stearic acid, benzoic acid and aluminum trimer to prepare composite aluminum soap; heating to refining and cooling to obtain the grease. The composite aluminum base grease has high water resistance, high antirust performance, high extreme pressure resistance, high mechanical stability and high temperature colloid stability.

Description

technical field [0001] The invention relates to a lubricating grease, in particular to a preparation method of a composite aluminum-based lubricating grease. Background technique [0002] Grease is a kind of lubricant, which is uniform and smooth solid or semi-solid, and is a colloidal dispersion system formed by uniformly dispersing a thickener in a lubricating base oil. The advantages of lubricating grease are: the lubricating device used is simpler than that of lubricating oil, the sealing effect is stronger than that of lubricating oil, and the service temperature is generally higher than that of lubricating oil. It is widely used in industrial fields, especially in metallurgical industry. [0003] Composite aluminum-based grease is a high-temperature grease that is widely used in steelmaking, rolling, sintering and other systems in the metallurgical industry. Such as the elastic slide of the sintering machine in the sintering system, the...
