Abstract

The invention provides a hard water-resisting high-performance cold rolling emulsion and a preparation method thereof, and belongs to the technical field of lubrication. The emulsion is obtained through the steps of compounding a modified phosphate extreme pressure agent with a pentaerythritol oleate oiliness agent, emulsifying with a TX series emulsifier and evenly mixing oil and water; and the ingredients and the diluted concentrations of different additives are adjusted to adapt to the production processes under different rolling conditions. The emulsion is composed of 20.0%-25.0% of machine oil N32, 34.0%-39.0% of coconut oil, 12.0%-16.0% of lard oil, 9.0%-11.0% of pentaerythritol oleate, 2.0%-3.0% of modified phosphate, 4.0%-5.0% of vulcanized fatty acid ester, 3.0%-5.0% of vulcanized lard oil, 2.0%-4.0% of petroleum sodium sulfonate T702, and 2.0%-4.0% of TX series emulsifier by mass percent. The hard water-resisting high-performance cold rolling emulsion has excellent combination properties and environmental friendliness, and is capable of replacing the rolling oil to a certain extent, and therefore, the environmental pollution can be reduced.

Description

technical field [0001] The invention relates to the technical field of lubrication and is used for lubrication in the cold rolling process of plate and strip steel, in particular to a high-performance cold rolling emulsion resistant to hard water and a preparation method thereof. Background technique [0002] In recent years, on the one hand, with the improvement of the market's requirements for the quality of strip steel and section steel, higher requirements have been put forward for the rolling process of steel products; on the other hand, the imported emulsion brands commonly used by major domestic steel mills are all It is required to use industrial soft water for preparation, which increases the cost to a certain extent and increases the possibility of failure. Therefore, finding an emulsion that can adapt to different water qualities is of great significance for saving production costs and improving the competitiveness of domestic emulsions.
