Problems solved by technology

However, most of the emulsifying waxes developed at home and abroad are nonionic and anionic emulsifying waxes, and cationic emulsifying waxes are easy to delaminate due to their unstable products. Therefore, the successfully developed cationic emulsifying waxes have not been reported yet.

Abstract

The cationic emulsifier wax includes paraffin, cationic surfactant, coemulsifier and water. It is prepared through the process including smelting and mixing paraffin and coemulsifier in the container with stirrer and heating to emulsifying temperature; heating to dissolve cationic surfactant in water inside one other container and heating to emulsifying temperature to prepare water solution of surfactant; adding the water solution of surfactant slowly into reactor while stirring for some period; cooling while stirring to room temperature and packing the product. The product may be stored stably for at least 60 days. It may be used as antistatic agent and softening agent for fabric.

Description

technical field [0001] The invention relates to a cationic emulsifying 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. According to the type of surfactant used, it can be divided into anionic emulsifying wax, nonionic emulsifying wax and cationic emulsifying wax. [0003] Since emulsified wax does not need to be melted by heating or dissolved by solvent, it has uniform film formation and good coverage, and is easy to be used in combination with aqueous solutions or emulsions of other substances. Very extensive: such as wood processing industry as a reinforcing agent for wood or fiberboard, and can also play a role in lubrication and demoulding; construction industry as a curing agent for reinf...
