Abstract

The invention relates to an emulsification technology of soybean oil, particularly to soybean oil emulsion and a preparation method thereof. The soybean oil emulsion comprises 1-5wt% of an emulsifier, 0.2-1wt% of xanthan gum, 0.01-0.05wt% of sodium nitrate, 4-10wt% of soybean oil, and 85-95wt% of water. Compared with the prior art, the invention solves the problems of instable emulsification of soybean oil and the like. The preparation method provided by the invention is simple and feasible, and low in cost, the emulsifier prepared by the method provided by the invention has good fluidity, water solubility and room temperature stability, is stable after standing at a room temperature for 1 year without demixing, and has good lubricating and temperature reducing properties, and the prepared emulsion can be widely applied to the mechanical processing industry.

Description

technical field [0001] The invention relates to soybean oil emulsification technology, in particular to soybean oil emulsion and a preparation method thereof. Background technique [0002] At present, in the process of metal cutting, various types of coolants, especially emulsions, are often used. Due to the excellent cooling and lubricating properties of the emulsion, it is not only widely used in the general metal cutting process, but also in some fields, it can be used in the hydraulic system of hydraulic machinery with high pressure to replace oil. However, the current emulsions are mainly chemical reagents, and the waste generated after the post-processing has polluted the environment. Therefore, those skilled in the art have been studying an emulsion that can replace chemical emulsifiers. [0003] Ma Hairan et al. used Span-60 and Tween-60 as emulsifiers to realize the dispersion of antioxidant green tea extract in glycerin. Jiang Lei used lecithin, xylitol and malt...
