Abstract
The invention relates to the technical field of lubricants and especially relates to a heatproof lubricant. The heatproof lubricant is prepared from 64-74wt% of base oil, 10-18wt% of an emulsifier, 0.4-1wt% of an antifoaming agent, 1-3wt% of a pour point depressant, 0.9-1.5wt% of an antirust agent, 3-7wt% of an anti-wear reagent at extreme pressure and 6-9wt% of a high temperature anti-oxidant. The heatproof lubricant has good integrated performances satisfying requirements, has good high temperature performances and lubrication performances, excellent oxidation stability, a very long service life at a high temperature, excellent extrusion performances and wear resistance and good bearing capacity, is suitable for lubrication and seal of a bearing, a valve and a friction part working under severe conditions of a very high temperature and heavy load, and can provide best wear-resistant, antirust and anticorrosion protection.
Description
Technical field
The present invention relates to technical field of lubricant, particularly a kind of heat resistant type lubricant.
Background technology
Lubricant is in order to reduce the friction resistance of friction pair, to slow down the lubricant medium of its wearing and tearing.Lubricant can also play the effects such as cooling, cleaning and preventing pollution to friction pair.In order to improve lubricity, suitable additive can be added in some lubricant.The kind of lubricant is a lot, be widely used in fields such as industry, agricultural, communications and transportation, national defense industry.
Along with the development of China's economy, industrialized level improves constantly, a large amount of use of Advanced Equipment technology and a large amount of introductions of external sophisticated equipment, many lubricant housings working temperature is more and more higher, and mechanical means requires that lubricant plays good lubrication under worst hot case; For this reason, the requirement of lubricant resistance to elevated temperatures is also improved constantly.In the high temperature lubricant starting evening of China, development is comparatively slow, and kind is desirable not enough.The most frequently used lubricant maximum operating temperature of current China is no more than 150 DEG C; When using in high temperature environments, be easy to volatilization, lose lubrication, cause equipment wearing serious, noise increases, and often stuck phenomenon occurs, substantially reduces the work-ing life of mechanical means.Therefore, the heat resistant type lubricant that can solve the problem must be developed.
