This shows; Automobile heavy-duty bearing railway grease of the present invention and preparation method thereof; Adopt polyisobutene class adhesive agent, 220CST viscosity naphthenic base oils, amino monothioester anti-wear agent, guarantee that railway grease adhesively in the bearing, guarantees that the low-temperature startup of railway grease is good; Guarantee that railway grease guarantees the lubricated of bearing under the situation that has big water gaging to exist, guarantee that simultaneously railway grease has the height property.This railway grease has excellent abrasion resistant extreme-pressure performance, guarantees the optimum load ability; Can reduce friction effectively by the utmost point, be controlled at bottom line to the heat that produces; Have excellent high temperature oxidation stability, guarantee the long-term works better of lubricant housings high temperature; Can all-round protection be provided to bearing, greatly prolong bearing life; The metallic surface there is splendid lubrication.And for above technique effect, the proportioning of embodiment one and processing parameter, result of use is best, obviously is superior to other embodiment, is the best.
Explanation is at last; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although with reference to preferred embodiment the present invention is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention; And not breaking away from the aim and the scope of technical scheme of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
