Abstract

The invention discloses cold-rolled emulsified liquid with iron powder self-dispersing performance and a preparation method thereof and relates to the field of lubricant and flat steel cold rolling. Dipentaerythritol oleate and naphthenic oil are selected as base oil, Span60 and Tween60 serve as emulsifiers, molybdenum dialkyldithiophosphate and monoolein serve as friction modifiers, dibutyl sulfo-amino lead formate serves as an extreme pressure antiwear additive, petroleum sodium sulfonate serves as an antirust agent, dinaphthyl methane sodium disulfonate and polyvinyl pyrrolidone serve as dispersing agents, and the cold-rolled emulsified liquid with the iron powder self-dispersing performance is prepared. The self-dispersing iron powder type cold-rolled emulsified liquid has excellent lubricity and corrosion inhibition anti-rust performance, harm of iron powder agglomeration to the rolled surface can be avoided, surface defects are reduced, and the anti-wear and anti-friction capacity of the emulsified liquid is improved through the micro-nano lubrication effect of iron powder.

Description

technical field [0001] The invention relates to the field of lubricant and cold rolling of strip steel, in particular to an emulsion used for lubrication in the cold rolling process of strip steel. Background technique [0002] Emulsion is widely used in the production process of cold-rolled strip steel because of its good lubricity and cooling properties. With the introduction of the national policy of "energy saving, consumption reduction, energy saving and emission reduction", while paying attention to the lubrication effect of cold rolling, enterprises have also begun to pay attention to cost saving, energy efficiency improvement, green production and other issues. During the cold rolling process, a large amount of iron powder will fall off the surface of the strip steel and the roll, and because the iron powder particles are small, the surface activity energy is high, and it is easy to aggregate. The traditional emulsion is generally composed of base oil, emulsifier, e...
