Abstract
The invention discloses extreme pressure composite lubricating grease and belongs to the technical field of lubricating grease. The lubricating grease is prepared from, by part, 100-120 parts of base oil, 30-40 parts of thickening agents, 2-5 parts of waterproof agents, 10-20 parts of extreme pressure anti-wear reagents and 15-30 parts of peptizing agents through reaction; the base oil is composed of polyolefin and fluorocarbon oil, and the thickening agents are composite soap base thickening agents. According to the extreme pressure composite lubricating grease, due to the special combination of the thickening agents and the base oil, and the extreme pressure anti-wear reagents with borate and boric acid ester components, the extreme pressure resistance is greatly improved while the better physical performance of the lubricating grease is ensured; the waterproof property is achieved, corrosion to metal is avoided, and the lubricating grease is environmentally friendly and has good practicality.
Description
Technical field
The invention belongs to technical field of lubricating grease, be specifically related to a kind of extreme pressure double composition grease.
Background technology
Lubricating grease is the grease-like semisolid of stiff, for mechanical friction portion, plays lubricated and sealing function.Also for metallic surface, rise and fill space and rust inhibition; It is mainly formed by mineral oil (or ucon oil) and viscosifying agent modulation.
When traditional lubricating grease uses, spread upon the metallic surface being in contact with one another, reach to the characteristic of radial compound, be just called the extruding of lubricating grease.In prior art, in the base oil of being everlasting, add soap base, strengthen the extrusion performance of lubricating grease, but the too much interpolation of soap base, be difficult to ensure whether other physical propertys of lubricating grease adapt with soap base addition, sometimes or even the effect that things turn into their opposites when they reach the extreme.
Summary of the invention
Goal of the invention: the object of the present invention is to provide a kind of extreme pressure double composition grease, make it overcome soap base in conventional grease formula and add the defect larger to lubricating grease change in physical properties, ensure the stability of lubricating grease physical property, keep mechanical stability, maintain normal, the reliable operation of mechanical means.
Technical scheme: for achieving the above object, the present invention adopts following technical scheme:
A kind of extreme pressure double composition grease is obtained by the composition reaction of following umber: 100 ~ 120 parts of base oils, 30 ~ 40 parts of viscosifying agents, 2 ~ 5 parts of water-resisting agents, 10 ~ 20 parts of extreme pressure anti-wear additives and peptizing agent are 15 ~ 30 parts; Described base oil is polyolefine and fluorocarbon oil composition; Described viscosifying agent is compound soap base viscosifying agent.
Described compound soap base viscosifying agent forming by higher aliphatic acid calcium and calcium acetate.
Described peptizing agent is the compound of organic acid, alcohol and polyvalent alcohol, ether and amine.
Described water-resisting agent is hexadecyl butenoic acid.
Described extreme pressure anti-wear additives is borate and/or boric acid ester.
Inventive principle: when mechanically activated, lubricating grease is subject to the effect of certain external mechanical force, first free oil in soap molecular lattice surface branches away, and then soap molecule wrecks, separate out more free oil, free oil except from being free in the free oil of soap molecular surface, also has the kapillary adsorbed oil discharging because of mechanical force, and under higher mechanical shearing, takes the carboxyl terminal of soap molecule apart and the expanded oil that discharges.Viscosifying agent is dispersed in relatively uniformly in base oil and is formed the solid particulate of grease structure, it is the important component of lubricating grease, character to lubricating grease has a great impact, the character of viscosifying agent and content have determined the sliminess of lubricating grease, the use properties such as water-fast and heat-resisting, the content of viscosifying agent is larger, thickening ability is stronger, and lubricating grease is thicker, and suitable viscosifying agent content can ensure the high temperature resistant and water resistance of lubricating grease.The anti-extreme pressure ability of borate, much larger than sulphur phosphorus type and the plumbous type additive of chlorine, is dispersed in amorphous microspheric borate the oily dispersion forming in lubricating oil; The not active element such as sulfur-bearing phosphorus chlorine, inert additwe, is dispersed in inorganic borate in mineral oil with superfine particle by dispersion agent (as anion surfactant petroleum sodium sulfonate), and dispersion system mesoboric acid salt is noncrystalline bead, mean diameter 0.1 μ m.But add after extreme pressure anti-wear additives, water resistance is slightly poor, and unstable in the situation that having water, the present invention uses in conjunction with water-resisting agent, has solved this problem.
Beneficial effect: compared with prior art, extreme pressure double composition grease of the present invention, by the special combination of viscosifying agent and base oil, add the extreme pressure anti-wear additives of borate and borate ester component, in ensureing the good physicals of lubricating grease, when greatly having strengthened anti-extreme pressure energy, take into account water resistance, and corrosion-free to metal, environmental friendliness, possesses good practicality.
