Abstract

The invention belongs to the technical field of lubricant, relates to a water-based hot rolling liquid containing nano TiO2 and a preparation method thereof and is used for the lubrication of steel plates and strips in the hot rolling process. The preparation method is characterized by selecting nano TiO2 having excellent corrosion inhibition and rust prevention performance as extreme pressure agent and using sodium hexametaphosphate and sodium dodecyl benzene sulfonate as dispersant, and comprises the following steps: sequentially adding deionized water, the sodium hexametaphosphate, the sodium dodecyl benzene sulfonate, triethanolamine, isothiazolinone, glycerol and benzotriazole; putting in a reaction kettle having a rotation rate of 80-120 r / min, and stirring while heating; when the temperature reaches 60 DEG C, adding the nano titanium dioxide, keeping the temperature, and continuously stirring for 30 minutes; and then, stopping heating, and further stirring until the temperature reaches room temperature, thus obtaining a white turbid liquid which is the required water-based rolling liquid. By using the water-based rolling liquid, the pollution caused by the traditional hot rolling oil can be reduced; the slow-release rust prevention performance of rolled steel products can be obviously improved; and the rolled steel products have favorable surface quality and long anti-corrosion period.

Description

[0001] technical field [0002] The invention relates to the technical field of lubricants, which are used for lubrication in the hot rolling process of plate and strip steel, in particular to a lubricant containing nano-TiO 2 A water-based hot rolling liquid and a preparation method thereof. [0003] Background technique [0004] In recent years, the hot-rolling process lubrication technology has been widely used, and the hot-rolling lubrication effect has also been recognized. However, most of the hot-rolling lubricants currently use hot-rolling oil. Harsh environment, polluted cooling water, poor corrosion and rust resistance of steel, etc. With the application of nanotechnology in all walks of life, nano water-based rolling fluid has made it a reality to replace oil with water. It has good lubricating and cooling performance, meets the requirements of hot rolling, has excellent corrosion inhibition and antirust performance, and is water-based with less pollution....
