Abstract
The invention discloses a kind of extreme pressure double composition grease, belong to technical field of lubricating grease, it is obtained by reacting by the composition of following number: base oil 100 ~ 120 parts, viscosifying agent 30 ~ 40 parts, water-resisting agent 2 ~ 5 parts, extreme pressure anti-wear additives 10 ~ 20 parts and peptizing agent are 15 ~ 30 parts; Base oil is polyolefine and fluorocarbon oil composition; Viscosifying agent is compound soap base viscosifying agent.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, while the good physicals of guarantee lubricating grease, while greatly strengthen anti-extreme pressure energy, take into account water resistance, and corrosion-free to metal, environmental friendliness, possesses 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 that the grease-like of stiff is semi-solid, for the friction portion of machinery, plays lubrication and sealing function.Also for metallic surface, rise and fill space and rust inhibition; It forms primarily of mineral oil (or ucon oil) and viscosifying agent modulation.
When traditional lubricating grease uses, spread upon the metallic surface contacted with each other, reach, to the characteristic with radial compound, is just called the Squeezing ground of lubricating grease.In prior art, in base oil of being everlasting, add soap base, strengthen the extrusion performance of lubricating grease, but the interpolation that soap base is too much, 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 reacting by the composition of following number: base oil 100 ~ 120 parts, viscosifying agent 30 ~ 40 parts, water-resisting agent 2 ~ 5 parts, extreme pressure anti-wear additives 10 ~ 20 parts 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 is made up of 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 the free oil being in soap molecular lattice surface branches away, and then soap molecule wrecks, separate out more free oil, free oil except from being free in except the free oil of soap molecular surface, the capillary attraction oil discharged because of mechanical force in addition, and take the carboxyl terminal of soap molecule and the expanded oil that discharges under higher mechanical shearing apart.Viscosifying agent is dispersed in base oil by relatively uniform the solid particulate forming grease structure, it is the important component of lubricating grease, the character of lubricating grease is had a great impact, the character of viscosifying agent and content determine 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 of lubricating grease and water resistance.The anti-extreme pressure ability of borate, much larger than sulphur phosphorous and chlorine lead-type additive, is dispersed in amorphous microspheric borate the oil-dispersions formed in lubricating oil; The not active element such as sulfur-bearing phosphorus chlorine, inert additwe, by dispersion agent (as anion surfactant petroleum sodium sulfonate) by inorganic borate with superfine Granular composite in mineral oil, dispersion system mesoboric acid salt is noncrystalline bead, mean diameter 0.1 μm.But after adding extreme pressure anti-wear additives, water resistance is slightly poor, unstable in the presence of water, the present invention uses in conjunction with water-resisting agent, solves 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, while the good physicals of guarantee lubricating grease, while greatly strengthen anti-extreme pressure energy, take into account water resistance, and corrosion-free to metal, environmental friendliness, possesses good practicality.
