Abstract

The present invention discloses a functional polymer covering liquid liquid lubricant additive, which is a polymer polymer layer on the surface of the ionic liquid on the surface of the ionic liquid, and through the polymer polymer on the polymer polymerThe surface modifier of the layer modifies the carbon -carbon dual -bond sirrius coupling agent is composed of the modified sulfonate layer of the surface of the polymer polymer layer by the cross -linked branches.The functional polymers of the present invention cover the ionic liquid liquid lubricating oil additive in the steel/steel friction vice, which significantly improves the decrease and abrasion resistance of lubricant additives in the friction sideline.Small friction and side loss and long service life.The present invention also disclosed the preparation method and application of functional polymer to cover the ionic liquid lubricant additive.

Description

technical field [0001] The invention relates to the technical field of lubricating oil additives, in particular to a functionalized polymer-coated ionic liquid lubricating oil additive and a preparation method and application thereof. Background technique [0002] The operation of equipment is inseparable from lubricating oil additives, and lubricating oil is inseparable from lubricating oil additives. Lubricating oil additives are the essence of modern advanced lubricating oils. According to statistics, about 30% of energy is consumed in friction, and 70% of damaged parts are scrapped by wear and tear. Therefore, improving lubricating properties to reduce friction, wear and prevent sintering is of great significance to the national economy. Commonly used additives in lubricating oil are divided into antioxidants, anti-wear agents, friction modifiers (also known as oily agents), extreme pressure additives, detergents, dispersants, foam inhibitors, anti-corrosion and anti-ru...
