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
The present invention relates to a kind of power lubrication fat, especially relate to a kind of ships aluminium sodium base grease.
Background technology
Power lubrication fat plays important effect to normal operation, minimizing mechanical friction wearing and tearing, the prolonged mechanical service life of equipment of safeguarding various mechanical means.The friction portion that is used for machinery plays lubricated and sealing function.Also be used for the metallic surface, rise and fill space and rust inhibition.Colloid stability is that lubricating grease maintenance in storing and using is colloid-stabilised, the performance that the liquid Dormant oils is not separated out from fat.Mechanical stability is expression lubricating grease is resisted consistency change under the machine work condition a performance.Lubricating grease is a kind of stable solid or the semi-solid product that viscosifying agent is scattered in the liquid lubricant to be formed, and wherein can add the additive and the filler that are intended to improve the lubricating grease specific character.Lubricating grease can be attached to vertical surface at normal temperatures and not run off, and can have irreplaceable the holding a little of other lubricant in the work of the friction position of unlimited or poor sealing.Many positions on ship machinery all use lubricating grease as lubricant, but lubricant effect is undesirable, and are of less types targetedly.
Summary of the invention
The present invention proposes for the problems referred to above, and purpose just provides a kind of marine propeller and Floating Crane and snagboat of being applicable to, a kind of preferably ships aluminium sodium base grease of lubricant effect.
In order to realize above purpose, technical scheme of the present invention is:
A kind of ships aluminium sodium base grease is characterized in that the ratio of weight and number of contained each composition is: 4～12 parts of stearic acids, 3～9 parts of winterized stearins, 5～15 parts of oleic acid, 3～15 parts in alum, 1～5 part of NaOH, 80～90 parts of 50# machinery oil and 60# locomotive oil mixing oils.
Described a kind of ships aluminium sodium base grease is characterized in that the ratio of weight and number of contained each composition is: 5～10 parts of stearic acids, 4～8 parts of winterized stearins, 7～12 parts of oleic acid, 5～11 parts in alum, 2～4 parts of NaOH, 80～90 parts of 50# machinery oil and 60# locomotive oil mixing oils.
Described a kind of ships aluminium sodium base grease is characterized in that the ratio of weight and number of contained each composition is: 8 parts of stearic acids, 6 parts of winterized stearins, 10 parts of oleic acid, 8 parts in alum, 3 parts of NaOH, 85 parts of 50# machinery oil and 60# locomotive oil mixing oils.
Prepare the processing method of described a kind of ships with the aluminium sodium base grease:
Except that sodium hydroxide, each component is added in mixing kettle, be heated to 100～105 ℃, after stirring, add water-soluble sodium hydroxide solution, carry out saponification reaction, fat again through displacement washing, is dewatered, is crowded into to refining, cooling is ground and is finished product.
The present invention compared with prior art has following advantageous effect: the present invention is applicable to marine propeller and Floating Crane and snagboat, dropping point is more than 75 ℃, have good water resisting property, protective and rust-preventing characteristic, existing proper lubrication trace, the swimming corrosion-resisting function, and have the function that lowers mechanical noise.
