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 [0001] The invention discloses a water-based lubricating nano-metal anti-friction and anti-wear strengthening agent and a preparation method thereof. Background technique [0002] Compared with ordinary metal materials, nano-metal materials show many special properties in many aspects such as magnetism, internal pressure, thermal resistance, chemical activity, mechanical properties, etc., so they are widely used in metallurgy, chemical industry, electronics, national defense and other fields. application prospects. [0003] The anti-friction and anti-wear properties of lubricants are strengthened and improved by additives. The use of nano-metal particles as lubricating additives has become a research hotspot in recent years, because it has been found that nano-metal particles added to lubricants can be used in friction The transfer film is formed during the process, which not only protects the surface of the friction pair and reduces wear, but also greatly r...
