Description
Technical field
The present invention relates to a kind of rust-proof type complex calcium sulfonate greases and preparation method thereof, belong to Composite calcium-sulfonate-batetrapolyurea profit
Consistent lubricant technical field.
Background technique
Composite calcium sulfonate grease lubricant is a kind of novel lubricating grease, and compared with other Hmp greases, performance is very comprehensive, this
Body just has excellent high-temperature behavior, water repelling property, extreme pressure and antiwear behavior and rustless property, and pump-conveying property also can satisfy collection
The needs of middle lubrication.The lubricant effect having under the harsh conditions such as high temperature, more water, heavy load at the same time will be substantially better than other profits
Consistent lubricant is conducive to simplify lubricating grease product especially suitable for the lubrication of equipment under steel mill's conticaster, Continuous mill train and conditions of similarity
Kind, facilitate and uses oil management.Specifically applicable position has: mine truck bearing；The main transmission bearing of dressing plant's ball mill；Sintering plant vibration
Dynamic screen axis is held；Iron-smelter coke bearing；Various continuous casting machine revolving platform gear rings；Secondary Cooling Zone of Continuous Caster, fan-shaped section, withdrawal straightening machine,
Rollgang bearing；Various strip mill ejection roller ways, roughing mill working roll, finishing mill working roll, batch machine bearing, tooth form connects
Hand, water pump bearing；Seamless steel tubing mill's pipe mill setting roll；The roller track bearing of Heavy Plate Plant operation roll of mill, heat-treatment furnace；
Profile, wire rolling plants operation roll of mill, cold bed bearing etc..Other high temperature, heavy load, more water occasions are applied also for, such as ship, resistance to
Fire, chemical industry, automobile and other industries equipment lubrication.
Composite calcium sulfonate grease lubricant at rouge mechanism include: high base number calcium mahogany sulfonate under the action of transforming agent by liquid
It is converted into semisolid smectic, is exactly grease of calcium sulfonic acid.High base number calcium mahogany sulfonate is by flux oil, sulfoacid calcium, calcium carbonate (nothing
Sizing) it forms, calcium carbonate is wrapped in the inside by sulfoacid calcium and forms stable micella, and outer EDS maps flux oil, whole system is in steady
Fixed transparent liquid condition.Transforming agent is usually the substance containing active hydrogen.Since the polarity of transforming agent is better than calcium carbonate, sulfonic acid
Calcium, which can separate out to make a return journey from micella middle reaches, wraps up transforming agent, originally stable stabilization micelle volume disequilibrium, wherein agraphitic carbon
Sour calcium separate out from micella is agglomerated into calcite shape crystal under the comprehensive function of transforming agent (including water).Reaction process
As follows: transforming agent and calcium carbonate reaction generate calcium salt (soap), carbon dioxide and water；Carbon dioxide, water and calcium carbonate generate carbonic acid
Hydrogen calcium；Calcium bicarbonate is heated to be decomposed into calcium carbonate, carbon dioxide, water again；This process carbon dioxide and water recycling, recycle into
Row, final almost all calcium carbonate separate out from stable micella form calcite shape crystal.Calcium carbonate crystal and sulfonic acid
Calcium phase, which is mutually adsorbed, forms partial size bigger colloidal particle or micelle, and colloidal particle or micelle interlock by molecular force and ionic forces formation
Network skeleton (i.e. gel structure), make oil be fixed in the gap of structural framework.Form using base oil as decentralized medium,
Using the gel particles of oil-containing as the two-phase structure disperses system of dispersed phase, it is formed lubricating grease.
Composite calcium sulfonate grease lubricant was just studied much and applies in the external eighties in last century, but ground at home
Study carefully later, be also confined on document mostly at present, really it is industrialized seldom.Currently, composite calcium sulfonate grease lubricant in the market
It is varied, but performance is mediocre, is unable to satisfy certain special requirements.
Summary of the invention
