Abstract
The invention provides calcium sulfonate complex grease. The calcium sulfonate complex grease comprises the following components in percentage by weight: 26-54 percent of lubricating base oil, 18-42 percent of thickening agent, 2-8 percent of OMRC, 3-5 percent of phase inversion accelerator, 2-6 percent of glacial acetic acid, 1-3 percent of fatty acid, 2-4 percent of antioxidant, 3-7 percent of calcium hydroxide and 1-3 percent of water. The calcium sulfonate complex grease provided by the invention has the advantages of wear resistance, pressure resistance, reduced temperature and noise, prolonged service life and the like, thereby reducing the maintenance frequencies of equipment and reducing the comprehensive expenses of the equipment; and the calcium sulfonate complex grease is suitably used on bearings, gears and chains. The calcium sulfonate complex grease cannot form liquid at the temperature of 260-300DEG C and then is cooled to room temperature, and finally the calcium sulfonate complex grease restores an original lubricating grease structure and the performance of the grease is unchanged. The calcium sulfonate complex grease has favorable reversibility which is not found in other soap greases. According to the calcium sulfonate complex grease disclosed by the invention, the wear to the surface of a friction pair is reduced to the minimum extent and environment friendliness and no toxicity are ensured.
Description
Technical field
The present invention relates to technical field of lubricating grease, particularly a kind of composite calcium sulfonate grease lubricant.
Background technology
As far back as the 1950's, just occurred with the high dropping point calcium sulfonate grease of calcium sulphonate, but, therefore failed effectively to be promoted because at this moment used oil-soluble sulfonic acid calcium thickening ability is little as viscosifying agent.The seventies in 20th century, the someone has invented changes newton's body calcium sulphonate into thixotropic non-newtonian fluid calcium sulphonate method, and has introduced the high alkalization technology of calcium sulphonate, has processed the high alkaline calcium sulfonate base grease.But the temperature pumping property of this product is not good, has hindered its application.20th century the mid-80, occurred with non-newtonian fluid calcium sulphonate and the compounded sulphonate complex calcium lubricating grease of other soap.
The common high dropping point grease that prior art provides; Just be absorbed in the unicity problem of dealing with on the mechanical means to be faced; Such as high temperature, at a high speed, high pressure or wear-resistant etc.; Can not be coupled to effectively among the requirement of modern production equipment high speed development, still can occur in actual the use because of the phenomenon that insufficient lubrication causes the equipment component heating, bearing failure is serious even shut down.
Summary of the invention
The present invention provides a kind of composite calcium sulfonate grease lubricant, its wear-resisting resistance to compression, the work-ing life of reducing rotatable parts such as temperature, minimizing noise, prolongation bearing.
To achieve these goals, the present invention provides following technical scheme:
A kind of composite calcium sulfonate grease lubricant, it is made up of following ingredients according to mass percent:
Lubricating base oil: 26～54%;
Viscosifying agent: 18～42%;
OMRC：2～8％；
Phase inversion promotor: 3～5%;
Glacial acetic acid: 2～6%;
Lipid acid: 1～3%;
Oxidation inhibitor: 2～4%;
Calcium hydroxide: 3～7%;
Water: 1～3%.
Preferably, said lubricating base oil is a MO, and its Saybolt viscosity rank is 500SN, and the kinematic viscosity in the time of 100 ℃ is 7～32mm/s
2
Preferably, said viscosifying agent is a high base number composite calcium sulfonate.
Wherein: OMRC (eutectic spin); A kind of high-effect wear-resistant Saving Energy by Lubrication oil additive; The composition that contains comprises: zinc dithiophosphate, metal-based sodium and organic aliphatic acid; This OMRC additive has excellent anti-oxidant, anti-extreme pressure, wear-resistant, Corrosion Protection, is a kind of multifunctional nano additive.
Preferably, said phase inversion promotor is a kind of or any two kinds of mixtures in lime carbonate, carbonic acid gas, Virahol, the alkaline earth metal halide.
Preferably, said lipid acid is one or both mixtures of Triple Pressed Stearic Acid or ten dihydroxystearic acids.
Preferably, said oxidation inhibitor is a kind of or any two kinds of mixtures of alkylphenol, dialkyl diphenylamine or ditertbutylparacresol.
Through implementing above technical scheme; Have following technique effect: the present invention provides composite calcium sulfonate grease lubricant; Wear-resisting resistance to compression, reduce temperature, reduce noise, prolong bearing work-ing life etc.; Thereby the minimizing apparatus maintenance, the comprehensive cost of reduction equipment is adapted at using on bearing, gear, the chain.At 310～350 ℃, do not become liquid, be cooled to room temperature then, become the structure of original railway grease again again, the performance of fat is constant, has good reversibility, and other soap grease do not possess this characteristic.
The OMRC nanometer additive that the present invention contains makes the surface of friction pair wearing and tearing reduce to minimum.
The present invention does not contain lead, mercury, cadmium, sexavalent chrome, PBBs and PBDE objectionable impurities, environment-protecting asepsis.
