Description

A kind of rust inhibiting lubricant composition and method of making the same

Technical field

The invention belongs to lubricating grease field, particularly a kind of rust inhibiting lubricant composition and method of making the same.

Background technology

In the various industrial fields such as iron and steel, automobile, general instruments, precision instruments, mostly use the lubricating oil being base oil with treated oil or synthetic oil.

In recent years, in order to meet the miniaturization of apparatus, low current, long service life, more and more require the rubbing characteristics and the wear resistant that improve lubricating oil.Meanwhile, consider the viewpoints such as energy-conservation, cost, environment, prevent metal rusting from seeming important all the more, accompany with it, the requirement improving lubricating oil rust-preventing characteristic is also more and more higher.

Automobile is as the class vehicles often used in people's life, not only provide convenience to people's trip, and just experiencing the vigorous growth phase, auto grease material not only requires water tolerance, low temperature properties and resistance to abrasion good, and needs to have the consistency of good rubber and long lifetime, high temperature resistant, resistance to low temperature.

Existing rust-inhibiting lubricant is attached to the surface of metallic weapon by immersion way; form layer protecting film; this protective membrane can the joint part of lubricated metal apparatus; prevent the oxygen in air from contacting with metallic weapon; to reach the work-ing life extending metallic weapon, play the effect of anti-rust and lubrication.In addition, this protective membrane is water-soluble substances, can be penetrated by high-pressure water vapor.Rust-inhibiting lubricant of the prior art is mainly used in the lubricating and antirust of metal-working industry and some Industrial Metal reactors, comprises water-based lubricant and oily lubricant.
