Description
Technical field
The present invention relates to automobile oil technical field, particularly to a kind of wear-resisting automobile oil and preparation method thereof.
Background technology
Current has the performance of many kollags very well, but owing to density can not be suspended in oil greatly, coarse size is entered not
Removing friction pair, mass deposition is serious, has used blocking oil circuit long, it is impossible to apply in lubricating oil.Pole in conventional lubrication oil
Pressure antiwear additive is often a little sulfur, phosphorus, chloride, generates metal compound by boundary lubrication TRANSIENT HIGH TEMPERATURE high pressure with friction pair
Thing, improves hardness and wear resistence.Though this compound is hard but the most crisp, constantly comes off at friction process and constantly formed,
Both having corroded parts, and consumed again additive, machinery or the service life of lubricating oil are the shortest.Conventional lubrication oil
In wear-resistant composition such as zinc dialkyl dithiophosphate (T202 oxidation and corrosion inhibitor) etc., sulfur-bearing, phosphorus, zinc, not only corrode silver
Bearing, poisons waste gas conversion equipment catalyst, goes back pollutant atmosphere.Lube product generally will be in the lowest environment temperature
Degree is lower to be used, the most in the winter time and under cold car state, therefore it is required that the lubricating oil used has good low temperature flow
Can, so not only contribute to the normal startup optimization of machine, it is also possible to reduce machine abrasion in start-up course.
