Embodiment Construction

[0030] The present invention will be further described below in conjunction with embodiment.

[0031] The preparation method of the metal wear self-repairing additive of the present invention comprises:

[0032] (1) Refinement, the existing micron-scale powder composite material with hydroxymagnesium silicate as the core is added with triethanolamine dispersant, and ground to nano-scale particles in a fine ball mill.

[0033] (2) Purification, using magnetic separation or flotation to remove impurities such as silicon compounds and chrysotile from the nanoscale metal friction self-repairing material particles mixed with triethanolamine.

[0034] (3) Particle modification, prepare a mixed solution of low base value synthetic calcium sulfonate and polyisobutylene bis-succinimide as a dispersant according to 1:1, and use a ratio of 1:1 according to the purified self-repairing material and the prepared dispersant 8, and then ultrasonically disperse through a homogenizer for 20 mi...

Abstract

The invention provides a preparation method of a metal abrasion self-reparation additive. The method comprises the steps of refinement, purification, particle modification, and the like. According to the invention, metal abrasion self-reparation material particles are refined into nano-grade micro-particles; and the micro-particles are subjected to purification and particle modification. Therefore, the dispersed suspension characteristic of the material micro-particles is improved. The prepared additive can be added and dispersed in advance in a lubricating oil, such that a lubricating oil with stable performance and a metal abrasion self-reparation function can be obtained.

Description

technical field [0001] The present application relates to the field of petrochemical technology, in particular to a method for preparing an additive with self-repairing function of metal wear, the additive prepared by the method, and lubricating oil containing the additive. Background technique [0002] For a long time, the wear of mechanical equipment due to metal friction has been one of the main reasons for the failure of various mechanical equipment or components, and the resulting economic losses are extremely huge. Therefore, how to reduce or overcome the wear and failure caused by metal friction is an urgent technical problem facing the world. for [0003] Metal wear self-repairing technology provides a brand-new anti-friction material for mechanical equipment and mechanical parts. Chinese invention patent application 200610016184.6 disclosed in some anti-friction materials), and added to various types of lubricating oil or grease for use. [0004] Lubricating oil...
