Abstract
A water based lubricating wearproof nanometer metal strengthening agent is metal nanometer granular sol, consisting of nanometer metal particles, dispersing medium, and assistants. The sol system is stable, no limitation to dilute and soluble into water and water-base lubricant. As additive for water-base lubricating, it forms nanometer metal transfering film with antifriction and antiwear functions on friction pair surface to improve performance of water-base lubricant. It achieves low cost, non-toxic and non-corrosive for mass production.
Description
Technical field
The invention discloses nano metal antifriction antiwear reinforcer of a kind of water based lubrication and preparation method thereof.
Background technology
Compare with ordinary metallic material, nano metal material demonstrates many special nature in all many-sides such as magnetic, interior pressure, thermal resistance, chemical activity, mechanical mechanics properties, thereby has a wide range of applications in every field such as metallurgy, chemical industry, electronics, national defence.
