A self-emulsifying paraffin wax is prepared from modified paraffin wax (70-90 wt.%), emulsifier (5-20 wt.%) and surfactant (1.2-20 wt.%) through fusing said modified paraffin wax and emulsifier, mixing them together and cooling. It is characterized by that when it is dissolved in hot water, a stable emulsion is generated.
Description
technical field [0001] The invention relates to a self-emulsifying paraffin and a preparation method thereof. Background technique [0002] As we all know, the emulsifying wax currently used is a kind of homogeneous fluid containing wax and water, which is made by dispersing various waxes including petroleum wax in water evenly under the action of mechanical external force by means of directional adsorption of emulsifier. . Therefore, the water content in emulsified wax is mostly more than 50%, and some are more. This just brings great inconvenience for the storage and transportation of emulsified wax. [0003] The phenomenon of self-emulsification was discovered by Gad in 1878. He found that sometimes lighter oil can be spontaneously emulsified in heavier water without mechanical stirring during the emulsification process. After that, the research on self-emulsification was mainly carried out with organic liquid as the research object. However, ...
