Preparation method for water-based steel strip-rolling solution containing nano ZnO

Abstract

The invention relates to a preparation method for a water-based steel strip-rolling solution containing nano ZnO, which belongs to the technical field of lubricant. The preparation method includes the following steps: glycerin, vulcanized castor oil, triethanolamine and oleic acid are sequentially added and heated and stirred in a reaction kettle at the rotation speed of 90 to 110 rotations per minute, and when the temperature reaches 80 DEG C, the temperature is kept and stirring is continuously carried out for 60 minutes; afterwards, the temperature is decreased to 70 DEG C, polyethylene glycol (PEG-4000), fatty acid imidazoline borate and fatty alcohol-polyoxyethylene (15) ether are sequentially added, and the temperature of 70 DEG C is kept and stirring is carried out for 30 minutes; and stirring is continued, the temperature is decreased to 60 DEG C, the nano ZnO is added, the temperature of 60 DEG C is kept constant and stirring is carried out for 60 minutes, heating is then stopped, water is added during stirring, and after being diluted to light milk white, the nano water-based steel strip cold rolling solution is prepared. The rolling solution is easy to use and convenient to operate, and is non-toxic and cannot produce pungent smell and oily fume in the process of rolling, the surface finish of a rolled steel strip is high, the annealing detergence is excellent, and the rolled steel strip does not have oily dirt.

Description

technical field [0001] The invention relates to the technical field of lubricants, which are used for lubrication in the cold rolling process of strip steel, in particular to a nanometer water-based cold rolling strip steel rolling fluid and a manufacturing method thereof. Background technique [0002] In the cold rolling industry of plate and strip steel, not only higher requirements are put forward for the quantity and quality of strip steel products, but also people pay more and more attention to clean production, energy saving and emission reduction in the cold rolling process. Liquid preparation puts forward higher requirements. The currently used rolling emulsion consumes a large amount of oil mist and seriously pollutes the environment, and the chemical substances such as extreme pressure agents, preservatives, and fungicides added to the emulsion cause serious pollution to the environment during the discharge of the emulsion after cold rolling. Therefore, a nano-wa...

Problems solved by technology

The currently used rolling emulsion consumes a lot, and the oil mist pollutes the environment seriously, and the chemical substances such as extreme pressure agents, preservatives, and fungicides added to the emulsion cause serious pollution to the environment during the discharge of the emulsion after cold rolling. Therefore, a nano-water-based cold-rolled sheet and strip rolling liquid with good lubricating performance and low pollution was invented to provide a reference for clean cold-rolled production
