The present invention provides a special composite emulsifier for a wax emulsion. The special composite emulsifier is characterized by comprising, by weight, 45-50 parts of peregal, 20-25 parts of stearic acid, and 25-30 parts of fatty alcohol polyoxyethylene ether. The process comprises: sequentially adding peregal, stearic acid and fatty alcohol polyoxyethylene ether to a reaction kettle, heating to achieve a temperature of 60-70 DEG C until completely melting the material, and stirring to achieve a uniform state so as to discharge the material. According to the present invention, during preparation of various wax emulsions, the emulsifier having the amount of 8-10% of the mass of wax and the wax are co-melted and then uniformly stirred, and hot water with a temperature of 90-95 DEG C is added until the solid content is 50% so as to obtain the corresponding wax emulsion, or deionized water can be added according to requirements so as to adjust the wax emulsion content to 5-50% and the like. The special composite emulsifier can be provided for emulsifying paraffin wax, polyethylene wax, palm wax, montan wax, beeswax, rice bran wax, candelilla wax, shellac wax, and other types of waxes, such that material preparation of wax emulsion manufacturers is simply, and the prepared emulsion is translucent, has blue light , and has characteristics of good stability and small particle size; and the emulsifying system is consistent, such that various wax emulsions can be compounded according to any ratios without generation of phenomena such as precipitation, flocculation, layering and the like, and the special composite emulsifier can be conveniently used in various fields.
