Environment-friendly composite multisoap base self-repairing bearing grease and preparation method thereof

Abstract

The invention relates to environment-friendly composite multisoap base self-repairing bearing grease and a preparation method of the bearing grease. The bearing grease is prepared from composite base liquid, a composite calcium soap thickening agent, an oxidation and corrosion resistant additive, a tungsten disulfide extreme pressure additive, a metal deactivator, a polarization graphite wear resistant additive, a self-repairing additive and a structure improving agent. According to the bearing grease provided by the invention, an additive containing non-heavy metal elements is used to replace the originally used additive containing heavy metal elements. Because base liquid, a thickening agent and an additive are all optimized, the bearing grease provided by the invention is more excellent in combination property and highlighted in abrasion resistance, maintains an excellent level in extreme pressure property, can fully meet the requirements of the bit bearing extreme pressure, the high temperature, a deep well with high temperature, the high-impact load and the abrasion resistance, meanwhile, can effectively supplement the defect that silver coating is not sufficiently brushed on the bearing axial diameter plane, and acts a function of repairing an abrasion resistant layer on a metal seal and a rubber seal of a bit bearing, so that the service life of the bearing is prolonged at a maximum level.

Description

field of invention

[0001] The invention relates to an environment-friendly composite multi-soap base self-repairing bearing grease and a preparation method thereof, in particular to a composite multi-soap base self-repairing bearing grease used for roller cone bits in the field of petroleum geological exploration and drilling and a preparation method thereof. Background of the invention

[0002] For the friction pair of ultra-high temperature, ultra-high pressure and high impact load, the addition of bearing grease containing additives of heavy metal elements plays a vital role in the effective lubrication of the friction pair. However, with the progress and development of human civilization, additives containing heavy metal elements have been proven to have serious destructive effects on human health and the living environment. This puts forward a new topic for the lubricating materials used in oil exploration and drilling of roller cone bit bearings: on the one hand, the a...
