Description
Technical field
The present invention relates to a kind of heat resistant type lubricating grease.
Background technology
Lubricating grease is to be scattered in a kind of stable solid or the semi-fluid colloidal dispersion system that forms in the liquid lubricant by viscosifying agent, and polarity abrim in disperse phase particulate and dispersion medium more can form firm lubricant film on friction surface.Simultaneously, because the viscosity ratio of lubricating grease basis oil viscosity is much bigger, oil film is also enough thick; Thereby lubricating grease has advantages such as good lubricity, is widely used in fields such as industry, agricultural, communications and transportation, national defense industry.
Along with China's constant development of economy, industrialized level improves constantly, a large amount of introductions of a large amount of uses of advanced equipment technology and external sophisticated equipment, many lubricant housings working temperature is more and more higher, and mechanical means requires lubricating grease to play good lubrication under worst hot case; For this reason, the requirement to the lubricating grease resistance to elevated temperatures also improves constantly.The high temperature grease of China starting evening, develop slowlyer, kind is ideal not enough.The most frequently used lubricating grease of China is to be the metal soap grease of base oil with mineral oil at present, and its maximum operating temperature is no more than 150 ℃; When using, be easy to softening and shedding and volatilization under hot environment, lose lubrication, cause equipment wearing serious, noise increases, and stuck phenomenon often takes place, and has shortened the work-ing life of mechanical means greatly.The heat resistant type lubricating grease that therefore, must development can address the above problem.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of lubricated and sealing that is applicable to the bearing, valve and the friction means that move under the bad working environments conditions such as very high temperature, heavy loading and humidity, pollution, and can provide the wear-resistant heat resistant type lubricating grease that undermines the rust resistance and corrosion resistance protection to greatest extent.
The present invention solves the problems of the technologies described above with following technical scheme:
Heat resistant type lubricating grease of the present invention adopts poly-internal olefin (PIO) compound as base oil with polyethers, uses the triuret viscosifying agent, cooperates multiple composite additive; Its each component and phase mass percent are:
| Component | Content (mass percent) |
| Base oil | 70%～80% |
| Viscosifying agent | 20%～12% |
| High-temperature antioxidant | 4%～6% |
| Extreme pressure anti-wear additives | 1%～2% |
| Rust-preventive agent | 0.2%～0.5% |
| Weighting agent | 0.8%～1.5% |
Base oil is that the poly-internal olefin (PIO) of mass ratio 40%～50% is compound with 60%～50% polyethers.
Viscosifying agent is the triuret viscosifying agent.
High-temperature antioxidant is that alkyl diphenylamine and 40%～30% the phenolic ester compounds of mass ratio 60%～70% is compound.
Extreme pressure anti-wear additives is that disulfo-dithiazole ketone and 40%～50% the dialkyl dithiophosphoric acid copper of mass ratio 60%～50% is compound.
Rust-preventive agent is that low alkali value calcium mahogany sulfonate and 30%～40% the high base number calcium alkylbenzenesulfonate of mass ratio 70%～60% is compound.
Weighting agent is tungsten disulfide.
The remarkable advantage of heat resistant type lubricating grease of the present invention has:
1. good combination property, every performance index all reach service requirements.Have good high temperature performance and lubricity, excellent high warm nature and oxidation stability, Chang high temperature life extremely, good extreme pressure property and wear resistance, frictional coefficient is extremely low, and supporting capacity is strong, excellent mechanical stability and water repelling property, the oil film strength height, outstanding anti-rust and anti-corrosion and biological degradability; Be applicable to the lubricated and sealing of the bearing, valve and the friction means that move under the bad working environments conditions such as very high temperature, heavy loading and humidity, pollution, and can provide wear-resistant to greatest extent and undermine the rust resistance and corrosion resistance protection.
2. the dialkyl dithiophosphoric acid copper that adopts of extreme pressure anti-wear additives belongs to the multiple-effect functional additive, not only itself have excellent wear-resistant, supporting capacity, rustless property can also produce good synergistic function with oxidation inhibitor, improves high-temperature oxidation resistance and the anti-hydrolysis ability of lubricating grease.
Embodiment
The present invention is directed to the harsh day by day applying working condition characteristics of bearing, gear and other friction means, adopt poly-internal olefin (PIO) compound as heat resistant type grease base plinth oil, triuret viscosifying agent with polyethers.By adopting artificial neural network algorithm, targetedly to multiple functional additive screening and prediction, and adopt genetic algorithm to carry out choosing of optimization prescription, seek the higher heat resistant type lubricating grease component of acquired price ratio.This component has good high temperature performance, high-temperature thermal oxidation stability, mechanical stability, water resisting property, corrosion-resisting resisting resistance and biological degradability; Its every physical and chemical index all reaches service requirements; can satisfy the lubricated and sealing of bearing, gear, chain and other friction part positions under high temperature, heavy loading or shock load, humidity, the contaminate environment, and provide wear-resistant to greatest extent and undermine the rust resistance and corrosion resistance protection.
