Abstract
The present invention belongs to a novel lubricant. Mother liquid which is prepared from water, a moisture absorbent, a metal deactivator and an antioxidant, and 0.1 to 10% of magnetic colloid are mixed to prepare the novel lubricant. The viscosity of the novel lubricant can be adjusted within the range of 20 to 300 centipoises according to requirements to meet different lubrication requirements. The novel lubricant is especially suitable for the lubrication of bearings and bearing shells, and is not lost or volatilized. The use period of the novel lubricant is long. The labor intensity of operation people is greatly lowered, and a lot of energy sources are saved.
Description
The invention belongs to a kind of novel lubricant.
Before the present invention realized, employed lubricant (fat) mostly was mineral lubricating oils (fat), and its shortcoming is: easily run off or leakage, must frequently refuel, cause mass consumption, increased labor intensity of operating personnel simultaneously; Because electrostatic precipitation causes dirty and easy cleaning not, power consumption is increased thereupon because viscosity is higher; In addition, clean a large amount of solvents or the clean-out system that parts consumed and because the volatilization of lubricating oil (fat) very easily causes environmental pollution and presence of fire.Sulfide in the mineral oil (fat) is harmful to HUMAN HEALTH simultaneously.
The objective of the invention is: the lubrication of a kind of aqueous lubricant proxy-mineral oil (fat) is provided, lubricated to bearing, bearing shell especially, thus solved the above-mentioned shortcoming that mineral oil (fat) exists, greatly reduce the cost of lubricating oil, save energy.
In the aqueous lubricant of the present invention, include antioxidant, metal passivator, thickening material is primarily characterized in that the magnetic colloid that also contains water, moisture adsorbent and be made up of ferromagnetic substance, thereby has solved loss, evaporation, the corrosion of metal problem of aqueous lubricant.
Antioxidant of the present invention can be that Sodium Nitrite or Sulfothiorine or S-WAT also can be other solubilities, stable antioxidant under neutrality or weak basic condition.Its consumption can be 1～5%.Described metal passivator can be that sodium phosphate salt is preferably Sodium phosphate dibasic, and its consumption can be 0.5～5%.Described thickening material can be that polyacrylamide also can be a sodium stearate, its consumption can for: when described lubricant viscosity is 20～50CP, can add polyacrylamide 0.1～0.5%; When described lubricant viscosity is 50～100CP, can add sodium stearate 0.5; When described lubricant viscosity is 100～300CP, can add sodium stearate 0.5～1%.Selected moisture adsorbent can be a polyvalent alcohol, glycerol preferably, and its add-on can be 30～40%.The add-on of described water can be 52～60%.Described magnetic colloid can be by ferromegnetism micelle, preferably Fe

4Can be 1: 3 with the amount ratio of water.The add-on of described magnetic colloid can be 0.1～10%.
Per-cent of the present invention is benchmark with the weight of the aqueous lubricant made all.
Lubricant of the present invention can be made up of mother liquor and magnetic colloid based on water.
Preparation is during mother liquor, after the water of getting aforementioned proportion at room temperature dissolves described antioxidant, metal passivator, adds described moisture adsorbent and stirs evenly as mother liquor standby.
During the preparation magnetic colloid, quartz sand, water, ferromagnetic substance are added in the sand mill in 10: 3: 1 ratio, ground 8～24 hours, then quartz sand is leached remaining paste magnetic colloid with 300～400 rev/mins rotating speeds.
Preparation adds 0.1～10% magnetic colloid during aqueous lubricant the difference that stirs evenly in the mother liquor according to the purposes of the difference of the add-on of described magnetic colloid or lubricant, adds an amount of thickening material.Promptly can be made into the various lubricants that viscosity is 20～300 centipoises by described operation.
Below be specific embodiments of the invention:
1. with 57% water described antioxidant Sodium Nitrite 2%, Sodium phosphate dibasic 1% are at room temperature dissolved, add glycerol 40% then, it is standby as mother liquor to stir evenly the back.
With quartz sand, water, Fe
3O
4Add in the sand mill in 10: 3: 1 ratios, ground 20 hours with 300 rev/mins rotating speeds, quartz sand is leached, remaining paste magnetic colloid is stand-by.
The magnetic colloid 0.5% of above-mentioned preparation is added mother liquor 99.3% and adds polyacrylamide 0.2%, stir, promptly can be made into the aqueous lubricant that viscosity is 35 centipoises.
2. with the above-mentioned magnetic colloid for preparing 5%, add the mother liquor 94.2% that makes.Stir, add 0.8% thickening material sodium stearate then, promptly can be made into the aqueous lubricant that viscosity is 200 centipoises.
The physico-chemical property of made aqueous lubricant is as follows:
1. outward appearance: pale brown look liquid
2. viscosity: 20～300CP(20 ℃)
3.pH be worth 7. neutrality
4. Applicable temperature-20～200 ℃
5. work-ing life: once filling can be used more than 3 months continuously.
The present invention can be different with the proportioning of mother liquor according to magnetic colloid, can satisfy different lubricating requirement by adding an amount of thickening material, are particularly useful for the lubricated of bearing, bearing shell, and the present invention is not run off, and is pollution-free, the unharmful substance volatilization.Not dust suction, it is convenient to clean, can secular continuous use, greatly reduce labor intensity of operating personnel.Simultaneously can save a large amount of energy.
