Abstract
The present invention discloses a composite additive for running-in or grinding of friction pairs of gears of internal combustion engie steel bushing, etc. and its preparation method. It is basically formed from extreme pressure agent, oily agent, antioxidant corrosion resistant, antirusting agent, emulsion-resisting agent and antiocagulant. On the premise of no damaging base body of friction pair is can raise running-in speed anjd shorten running-in time.
Description
The present invention relates to a kind of lubricating oil additive, particularly relate to running-in composite additive and preparation method thereof such as a kind of gear and oil engine steel bushing.
As everyone knows, gear and oil engine steel bushing and piston ring etc. be modern age automobile and machinery equipment in most widely used two kinds of transmission mechanisms, at present the running-in method that adopts has: add grit running-in etc. in running-in under the running-in of standard running-in oil, the gear oil underload, the lubricating oil.Its shortcoming is owing to adopt the underload running-in, makes long increasing of seating time, the running-in weak effect, and the surface quality after the running-in is not high.
The purpose of this invention is to provide a kind of lubricant additive that can satisfy gear or quick running-in such as oil engine steel bushing and piston ring simultaneously.
