Abstract
The invention provides a lubricating grease comprising the following components by the mass fraction: 14%-22% of stearic acid, 3%-5% of an alkaline earth metal, 0.7%-1.3% of 2,6-di-tert-butyl-4-methyl phenol, and the balance alkane. The lubricating grease is stable in structure and strong in adsorption capacity, thereby being good in sealing performance; the lubricating grease is also not easy to oxidize, is white in color, is non-toxic and harmless, and especially can be used in lubrication for food machinery and textile machinery.
Description
Technical field
The invention belongs to field of fine chemical, relate to a kind of lubricating grease.
Background technology
Lubricating grease is used in reduce friction in all kinds mechanical means, the semi-solid lubricants of protection machinery and workpiece, also for metallic surface, rises and fill space and rust inhibition.Lubricating grease forms primarily of mineral oil (or ucon oil) and viscosifying agent modulation, mainly play lubrication, damping, reduction noise, antirust, clean, seal and the effect such as buffering.
Lubricating grease is complicated hydrocarbon polymer and the mixture of additive, and its real use properties is complicated physics or the combined effect of chemical change process.Lubricating grease adsorptive power is in the market poor, easily run off, and lubricating grease is easily oxidized, and color is rendered as micro-yellow, and in food machinery and textile manufacturing machine, application exists considerable influence.
Summary of the invention
The present invention, in order to solve the problem, provides a kind of lubricating grease, reaches adsorptive power strong, not easily runs off, good seal performance, the brilliant saturating object of color and luster white.
For achieving the above object, the present invention is by the following technical solutions:
The invention provides a kind of lubricating grease, described lubricating grease comprises the component of following massfraction:
Stearic acid 14%-22%,

Surplus is alkane.
Further, described alkane is long chain alkane, and the carbonatoms of alkane is more than or equal to 30.Sufficiently long carbochain is very important for formation this skeleton of grease base of the present invention.Under optimum condition, the carbonatoms of alkane is between 30-50.
Further, described alkaline-earth metal is one or more in magnesium, calcium, strontium, barium.
Further, described alkaline-earth metal is magnesium or calcium.
In addition lubricating grease of the present invention can also add other additives according to actual needs, such as oxidation inhibitor and metal passivator, extreme pressure anti-wear additives, friction modifier, detergent-dispersant additive, froth suppressor, rust-preventive agent, antioxidant preservative, flow point activator, viscosity index improver, anti-emulsion etc.
Further, described lubricating grease comprises the component of following massfraction:
Stearic acid 16%-20%,
Magnesium or calcium 3%-5%,
2,6-toluene di-tert-butyl phenol 0.9%-1.1%,
Surplus is alkane, and the carbon atom number of alkane is between 35-50.
Further, described lubricating grease comprises the component of following massfraction:
Stearic acid 17-19%,
Alkaline-earth metal 4%,
2,6-toluene di-tert-butyl phenol 1%,
Surplus is alkane, and the carbon atom number of alkane is between 35-50.
Further, described lubricating grease comprises the component of following massfraction:
Stearic acid 18%,
Alkaline-earth metal 4%,
2,6-toluene di-tert-butyl phenol 1%,
Surplus is alkane, and the carbon atom number of alkane is 40.
Compared with prior art, the technical program has the following advantages:
The present invention by a large amount of creative work, finds out proper lubrication fat formula, adopts the present invention to fill a prescription the lubricating grease of preparation, skeleton structure is not loose, soda acid reasonable ratio, and the reaction that organises with alkaline-earth metal is more complete, final obtained grease structure is stablized, adsorptive power is strong, thus good seal performance, not oxidizable yet, color is white, and nontoxic, be particularly useful for food machinery or textile manufacturing machine lubrication use, play lubrication, noise reduction, anticorrosion, seal effect.
