Emulsified microcrystalline wax and its preparation method

Abstract

The invention discloses an emulsified microcrystalline wax and a preparation method thereof. The emulsified microcrystalline wax includes components such as microcrystalline wax, anionic surfactant, nonionic surfactant and co-emulsifier. Put a certain amount of microcrystalline wax, nonionic surfactant, and co-emulsifier into a container with a stirring device, stir and heat at a low speed to melt and mix evenly, and heat to the emulsification temperature; put a certain amount of anionic surfactant In another container, add a certain amount of water and heat it to dissolve, and raise the temperature to the emulsification temperature to make a surfactant aqueous solution; under stirring, slowly add the surfactant aqueous solution into the reactor, and then stir at constant temperature for a certain period of time ; Stir and cool to room temperature, and it will be the product after canning. The product is stable for at least 60 days, has good water dispersibility, simple equipment required for preparation, easy operation of process conditions, and low production cost.

Description

technical field [0001] The invention relates to an emulsified microcrystalline wax and a preparation method thereof. Background technique [0002] Emulsified wax is a kind of uniform fluid containing wax and water made under the action of external mechanical force by dispersing various waxes including petroleum wax evenly in water, with the help of directional adsorption of emulsifier. [0003] Since the microcrystalline wax emulsion does not need to be melted by heating or dissolved in a solvent, it is easy to be used in combination with aqueous solutions or emulsions of other substances, and has the advantages of safety, high efficiency, economic convenience, etc. OK, so microcrystalline wax emulsion has superior performance than paraffin wax emulsion in high-grade leather finishing, household appliances, furniture, automobile and floor waxing and glazing. However, since the interfacial tension between microcrystalline wax and water is much greater than that between paraf...

AI Technical Summary

Problems solved by technology

However, since the interfacial tension between microcrystalline wax and water is much greater than that between paraffin wax and water, microcrystalline wax is more difficult to emulsify. The research on emulsified microcrystalline wax prepared by emulsifying raw materials has not been reported yet
