Abstract
A composite refractory urea-base grease with high refractory performance, water-proofing nature and extreme-pressure performance is prepared through proportionally mixing high-viscosity mineral oil with isocyanate, fatty amine and arylamine, reaction, heating to 100 deg.C, adding low-molecular acid salt, heating to 180 deg.C, high-temp refining, cooling to 100 deg.C, adding antioxidizing agent, extreme-pressure agent and antirust agent, homogenizing and filter.
Description
Technical field
The present invention relates to a kind of lubricating grease, is to be base oil with the high viscosity mineral oil, is viscosifying agent with the composite polyurea, adds the composite high temperature areidofat of multiple efficient additive.
Background technology
The equipment many places of steelworks are moved under the condition of high temperature, Duo Shui, impact load in the metallurgical industry, as positions such as crystallizer, fan-shaped section, straightening machine bearings.The PERFORMANCE OF GREASES used to the steelmaking equipment bearing proposed higher requirement.
The lubricating grease that is used for the steelmaking equipment bearing is many based on extreme pressure compound lithium or clad aluminum, but the high-temperature behavior of this lipoid and bearing life are not fine, often at high temperature thinning trickling, cause the storage of lubricating grease in bearing to tail off, the stuck bearing of fat coking in bearing when serious, thereby influence lubricant effect, brought inconvenience also for production and maintenance, influenced the benefit of steel mill.
Summary of the invention
The purpose of this invention is to provide a kind of is viscosifying agent with the composite polyurea; with the high viscosity Dormant oils is base oil; the lubricating grease composite high temperature areidofat that adds multiple functional additive, through how tame steelworks evidence, this fat high temperature does not run off; noncoking; water resisting property is good, has prolonged duration of service, has reduced maintenance times; provide good lubrication protection to bearing, made steelworks receive considerable overall economic efficiency.
Composite high temperature areidofat is characterized in that with the high viscosity Dormant oils be base oil, is viscosifying agent with the composite polyurea, and adding oxidation inhibitor, extreme pressure agent, rust-preventive agent are made, and wherein the weight part proportioning of each composition is as follows:
High viscosity Dormant oils: 70-75
Composite polyurea: 15-20
Oxidation inhibitor: 0.5-2
Extreme pressure agent: 3-6
Rust-preventive agent: 0.5-2
Described high viscosity Dormant oils is meant the mixing oil of 150BS and 400SN, and its kinematic viscosity of 100 ℃ is 20-25mm
2/ s.
Described composite polyurea is meant the polyureas product of isocyanates and fatty amine and aromatic amine reaction and the complex thickener that low molecular acid salt is formed.Described low molecular acid salt is meant calcium acetate.
Described oxidation inhibitor is meant phenyl-a-naphthylamine.
Described extreme pressure agent is meant borate family compound or phosphoric acid ester or phosphite ester compound.
Described rust-preventive agent is meant the barium mahogany sulfonate compounds.
The production technique of composite high temperature areidofat is: weight part proportioning in accordance with regulations adds base oil, add isocyanates, fat amine and aromatic amine react the polyureas product, be warmed up to 100 ℃ and add low molecular acid salt, the highlyest be warmed up to 160 ℃ and carry out high temperature refining, cool to 110 ℃ and add oxidation inhibitor, extreme pressure agent, rust-preventive agent, carry out aftertreatment with clarifixator then, filter packing.
The present invention has following advantage;
1) high-temperature behavior is outstanding, and dropping point does not trickle during high temperature up to more than 260 ℃, noncoking;
2) water repelling property excellence, 38 ℃ of water drench number of dropouts and have only 2%, and it is few to guarantee to run off when big water gaging washes away;
3) extreme pressure property height, four-ball tester PB value can reach more than the 980N, and the PD value can reach more than 4900, is fit to the heavy loading operating mode.
4) high-temperature bearing that is fit to steelworks uses, noncoking, and axis does not hold, long service life.
