Problems solved by technology

At present, emulsions are mainly used as lubricants for cold rolling. Traditional emulsions are prone to deterioration and degradation during the rolling process due to the contamination of solid impurities and miscellaneous oils, bacterial reproduction and other factors, which affect their performance and service life.
The deterioration of the emulsion seriously affects the lubrication in the rolling process, causing surface defects of the product and reducing the qualified rate of the product, while the frequent replacement of the emulsion will increase the production cost and increase the burden on the environment

[0013] Embodiment 1 formula sees the following table:

[0014]

[0015]

[0016] According to the weight formula of each component in the above table, prepare nano-TiO 2 antibacterial cold-rolled emulsion. Add pentaerythritol oleate (1.0g), isooctyl palmitate (1.8g), sodium petroleum sulfonate (0.1g), and sulfurized fatty acid (0.3g) into the beaker in order, and put them on the constant temperature electromagnetic stirrer Heat to 80°C while stirring, and keep stirring at constant temperature for 10 minutes. Cool to 70°C, then add Span80 (0.2g), Tween80 (0.2g), and stir at constant temperature for 25 minutes to obtain cold-rolled emulsified oil for strip steel, add it to deionized water, stir at constant temperature for 15 minutes, and cool to room temperature. That is, the basic cold rolling emulsion is obtained.

Abstract

The invention provides a nano-TiO2-containing antimicrobial rolling emulsion and a preparation method thereof, relating to the technical field of lubricants and biology. The base emulsion with lubricating properties is prepared by using pentaerythritol oleate and isooctyl palmitate as base oil, Span 80 and Tween 80 as emulsifiers, sulfurized fatty acids as an extreme-pressure antiwear additive and sodium petroleum sulfonate as a rust inhibitor. Nano TiO2 with the particle size of 15-35nm in the dry powder state is selected, ethylene glycol and sodium hexametaphosphate are used as dispersing agents, and the nano TiO2 is uniformly and stably dispersed in to the base emulsion. By using a plate count process as a reference, the proportion of the nano TiO2 to the dispersing agents, the nanoparticle dispersion time and the temperature are regulated to obtain the production technique with different dispersion effects and antimicrobial effects. The antimicrobial cold-rolling emulsion has the advantages of favorable antibacterial property, favorable lubricating property, favorable corrosion inhibition property and favorable rust resistance, and has certain nano filling self-repair functions on the surface defects after rolling.

Description

[0001] The invention relates to the field of lubricant and biotechnology, and is used for lubrication in the cold rolling process of plate and strip steel. Specifically, it is a nano-TiO 2 Antibacterial rolling emulsion and preparation method thereof. Background technique [0002] The lubrication technology of strip steel cold rolling process is widely used. With the development of technology, 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. At present, emulsions are mainly used as lubricants for cold rolling. Traditional emulsions are prone to deterioration and degradation during the rolling process due to contamination by solid impurities and miscellaneous oils, bacterial reproduction and other factors, which affect their performance and service life. The deterioration of the emulsion seriously affects the lubrication during the ro...
