Example Embodiment

[0011] Example 1

[0012] An aluminum-sodium-based grease for ships. The weight ratio of each component is: 8 parts stearic acid, 6 parts hardening oil, 10 parts oleic acid, 8 parts alum, 3 parts NaOH, 50# mechanical oil Mix 85 parts with 60# cylinder oil. The process method for preparing the described sodium-aluminum-based grease for ships: except sodium hydroxide, add each component into a mixing kettle, heat to 100-105°C, add hydrogen dissolved in water after stirring The sodium oxide solution undergoes saponification reaction, refining, and then undergoes displacement washing, dehydration, thickening into fat, cooling and grinding are finished products.

Example Embodiment

[0013] Example 2

[0014] An aluminum-sodium-based grease for ships, the weight ratio of each component is: 4 parts stearic acid, 9 parts hardened oil, 15 parts oleic acid, 15 parts alum, 5 parts NaOH, 50# mechanical oil Mix 90 parts with 60# cylinder oil. Others are the same as in Example 1.

Abstract

The invention relates to a mechanical lubricating grease, in particular to a sodium aluminate soap grease for a ship. The sodium aluminate soap grease comprises the following components in parts by weight: 4-12 parts of stearic acid, 3-9 parts of hardened oil, 5-15 parts of oleic acid, 3-15 parts of white alum, 1-5 parts of NaOH, 1-5 parts of 50# machine oil and 80-90 parts of 60# cylinder mixed oil. The sodium aluminate soap grease for the ship is suitable for a ship propeller, a floating crane and a dredge boat, the dropping point is above 75 DEG C, the sodium aluminate soap grease has good water resistance, protective property and anti-corrosive performance, the sodium aluminate soap grease not only has the function of proper lubrication, but also has the anti-corrosion performance, and has the function of reducing the mechanical noise.

Description

technical field [0001] The invention relates to a mechanical lubricating grease, in particular to an aluminum sodium base lubricating grease for ships. Background technique [0002] Mechanical grease plays a very important role in maintaining the normal operation of various mechanical equipment, reducing mechanical friction and wear, and prolonging the service life of mechanical equipment. It is used in the friction part of the machine to lubricate and seal. It is also used on metal surfaces to fill voids and prevent rust. Colloidal stability is the property that the lubricating grease keeps the colloid stable during storage and use, and the liquid mineral oil does not separate out from the grease. Mechanical stability refers to the performance of grease against changes in consistency under mechanical working conditions. Grease is a stable solid or semi-solid product composed of a thickener dispersed in a liquid lubricant, in which additives and fillers can be added to im...
