Abstract

The invention discloses a nitrogen-containing dual-phase stainless steel cold-rolled profile lubricant composition, which uses ethylene glycol oleate (acid value<8mgKOH / g):VHVI 4 mass ratio=1:2 compound as the compound semi-synthetic base oil , blended with a variety of compound additives. It includes: antioxidant, oily agent, friction reducer, antiwear agent, rust inhibitor, metal passivator, antioxidant and anticorrosion agent, antifoaming agent, reinforcing agent, cooling agent, etc. The invention has good thermal oxidation resistance, surface damage resistance, extreme pressure bearing capacity, reduced friction coefficient, good adhesion, diffusivity, anti-pollution and separation from metal residues, not easy to oxidize, and good Filterability, cooling and cleaning performance.

Description

technical field [0001] The invention belongs to the technical field of lubricants. Specifically, it is a nitrogen-containing dual-phase stainless steel cold-rolled profile lubricant composition. Background technique [0002] In terms of chemical composition, stainless steel is a high-alloy steel based on iron and carbon that contains more alloying elements. Stainless steel is a special steel in terms of physical and chemical properties. Stainless steel includes acid-resistant steel, skin-free steel and resistance alloys, etc. Their common feature is that they can resist corrosion in air and weak corrosive media-that is, they are not easy to generate francium. Because these steels are not easy to rust, people collectively call them stainless steel. Stainless steel is not absolutely free from rust and corrosion, but the amount of rust and corrosion is small; the process of rust and corrosion is slow, or even imperceptible. Therefore, stainless only has a relative meaning, ...
