Description

A kind of soybean oil emulsion and preparation method thereof
Technical field
The present invention relates to the emulsifying technologies of soybean oil, in particular to soybean oil emulsion and preparation method thereof.
Background technique
At present in metal cutting process, commonly using the coolant liquid of various models, especially emulsion.Due to cream Changing liquid has excellent cooling performance and greasy property, is not only widely used in common metal cutting process, but also In certain fields, it can be applied in the hydraulic system of the hydraulic machinery with high pressure, to substitute oils.And current cream Changing liquid is mainly chemical reagent, and the waste that generation is post-processed to it causes pollution to environment.Therefore those skilled in the art A kind of emulsion that can substitute chemical emulsifier is being studied always.
Ma Hairan etc. uses Arlacel-60 and Tween-60 to realize antioxidant green-tea extract in glycerol as emulsifier In dispersion.Jiang Lei realizes emulsion dispersion of the olive oil in glycerol using lecithin, xylitol and maltitol.
Relevant report at present about soybean oil emulsification is seldom.
Summary of the invention
The present invention is to make up the deficiencies in the prior art, provides a kind of preparation method of soybean oil emulsion, emulsion tool There are excellent cooling, lubricating action.
Soybean oil is common oil for cooking in people's daily life.Soybean oil is prepared into after stable emulsion one The fields such as a little machinings can also be used as cooling, the emulsifier of lubrication uses.
To achieve the above object, the invention adopts the following technical scheme: a kind of soybean oil emulsion, comprising: emulsifier 1- 5wt%, xanthan gum 0.2-1wt%, sodium nitrate 0.01-0.05wt%, soybean oil 4-10wt%, water 85-95wt%.
Preferably, the soybean oil emulsion includes: emulsifier 1-4wt%, xanthan gum 0.2-0.5wt%, sodium nitrate 0.01-0.05wt%, soybean oil 4-6wt%, water 90-95wt%.
Further, the emulsifier is Emulsifier EL-60.
Further, the Emulsifier EL-60 by 1 mole of castor oil and 20~40 moles of ethylene oxide contractings and And it obtains.
Further, the soybean oil is soybean grease.
Another object of the present invention is that the preparation method of above-mentioned soybean oil emulsion is claimed, and specifically includes following step It is rapid:
(1) at room temperature to equipped with water and Emulsifier EL-60 are added in mulser container, in revolving speed 2500- It is stirred 5-10 minutes under 3500rpm；
(2) sodium nitrate is added in the mixture obtained to step (1), 5-10 points is stirred at revolving speed 2500-3500rpm Clock；
(3) soybean oil is added dropwise in the intermediate product obtained to step (2), is kept stirring rate in 2500-3500rpm, stirs It mixes 20-30 minutes；
(4) xanthan gum finally is added into step (3) products therefrom at revolving speed 2500-3500rpm, and continues to stir 20-30 minutes.
The utility model has the advantages that
The present invention solve soybean oil emulsification it is unstable, those skilled in the art are not selected as emulsification all the time Agent raw material, the problems such as limiting its application.Of the invention preparation method is simple, at low cost, emulsifier tool prepared by the present invention There are excellent mobility, water solubility and room temperature stability, stand 1 year stabilization at room temperature, keeps not stratified, and have good Lubrication and temperature reduction performance, the emulsion of preparation can be widely applied to mechanical processing industry.
