Abstract
The invention discloses a high temperature-resistant water spraying-resistant radiation-resistant wear-resistant lubricating grease composition. The lubricating grease composition utilizes poly(alpha-alkene)-metallocene PAO (synthetic base oil) compound as base oil and a plurality of additives such as a densifier, an anti-oxidant, an antirust agent, an extreme pressure agent, an antiwear agent, a metal fatigue-resistant agent, a binder, an antioxidant antiseptic, an assistant and a strengthening agent. The high temperature-resistant water spraying-resistant radiation-resistant wear-resistant lubricating grease composition has high temperature resistance, good lubrication effects, heavy load resistance, impact resistance, excellent extreme pressure property and good water resistance, is not lost, softened and deteriorated under the condition of cooling water spraying, has good pumping performances, ensures full lubrication of all lubrication parts, has good adhesiveness, prevents bearing separation in bearing operation, has good mechanical stability, is not diluted and lost under action of mechanical shearing, has good corrosion resistance and does not corrode a lubrication part.
Description
Technical field
The invention belongs to lubricating grease field, particularly the high temperature resistant resistance to trickle radiation hardness antiwear lubricating grease composition of one.
Background technology
When Nuclear power plants and nuclear power source boat run, under normal circumstances, lubricating grease, after changing the radiation exposure of doses, because grease structure is damaged in various degree, can cause grease dropping point to reduce, denseness deliquescing or sclerosis, and then putrid and deteriorated.This kind of equipment contacted with radioactivity, is required that lubricating grease has good radiation resistance.Meet that high temperature, humidity or water drench, the lubricant of the special operation condition of wear-resistant, high bearing capacity simultaneously, slideway abrasion loss is had substantial degradation.It has high temperature resistant, normally can work at-20 ~ 250 DEG C of temperature; Do not run off, noncoking, not blocking pipe, can play good lubrication; Anti-heavy loading, shock resistance, have excellent extreme pressure property; Water resisting property is good, under cool water shower condition, does not run off, not softening rotten; Pump-conveying property is good, guarantees the sufficient lubrication of each lubricant housings; Good adhesivity, when ensureing bearing operation, is not thrown out of; Good mechanical stability is not thinning, loss by mechanical shearing; Good non-corrosibility, does not corrode lubricant housings.
Summary of the invention
The technical problem to be solved in the present invention is to provide one and has high temperature resistant, can play good lubrication; Anti-heavy loading, shock resistance, have excellent extreme pressure property; Water resisting property is good, under cool water shower condition, does not run off, not softening rotten; Pump-conveying property is good, guarantees the sufficient lubrication of each lubricant housings; Good adhesivity, when ensureing bearing operation, is not thrown out of; Good mechanical stability, by not thinning during mechanical shearing, loss; Good non-corrosibility, does not corrode the high temperature resistant resistance to trickle radiation hardness antiwear lubricating grease composition of lubricant housings.
The present invention adopts following technical scheme to solve the problems of the technologies described above:
A kind of high temperature resistant resistance to trickle radiation hardness antiwear lubricating grease composition, adopt the poly-alpha olefins of mass ratio 50% and the metallocene PAO synthetic base oil of 50% to be complex as base oil, coordinate multiple additives, its each component and mass percent thereof are:
| Component | Mass percent content |
| Base oil | Surplus |
| Viscosifying agent | 11％～16％ |

| Extreme pressure agent | 3％～6％ |
| Anti-wear agent | 2％～3％ |
| The tired agent of anti-metal | 2.2％～3％ |
| Adhesive agent | 3％～4.5％ |
| Antioxidant preservative | 2％～3％ |
| Auxiliary agent | 0.3％～0.6％ |
| Strengthening agent | 1％～2％ |
Viscosifying agent is the 2,4 toluene diisocyanate of mass ratio 44% and 34% 4,4
,-benzidine and 22% lime acetate compound.
Oxidation inhibitor is the phenyl-a-naphthylamine of mass ratio 50% and 2,2, the 4-dimethyl dihydroquinoline compounds of 50%.
Rust-preventive agent is the sebacic acid sodium of mass ratio 50% and the alkenyl succinic acid T746 compound of 50%.
Extreme pressure agent is No. 1 oildag.
Anti-wear agent is thiophosphoric acid amine salt T308.
The tired agent of anti-metal is aryl boric acid.
Adhesive agent is polyisobutene T603D.
Antioxidant preservative is dialkyldithiocarbamacompositions sulfuration oxygen molybdenum.
Auxiliary agent is Isosorbide-5-Nitrae-diaza-bicyclo octane; Strengthening agent is sulphur phosphorus fourth octyl group zinc salt T202.
Remarkable advantage of the present invention is:
Have high temperature resistant, good lubrication can be played; Anti-heavy loading, shock resistance, have excellent extreme pressure property; Water resisting property is good, under cool water shower condition, does not run off, not softening rotten; Pump-conveying property is good, guarantees the sufficient lubrication of each lubricant housings; Good adhesivity, when ensureing bearing operation, is not thrown out of; Good mechanical stability, by not thinning during mechanical shearing, loss; Good non-corrosibility, does not corrode lubricant housings.
