Abstract

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.

Description

technical field [0001] The invention relates to a special composite emulsifier for wax emulsion and a preparation method thereof, belonging to the technical field of chemical industry related to the preparation of wax emulsion. Background technique [0002] Wax emulsion is a water-containing uniform fluid formed by wax under the action of emulsifier and mechanical force. It is easy to compound with other emulsions or diluted with water. It has the advantages of safety, high efficiency, economy and environmental protection. It is a widely used Chemical Products. For example, low-content wax emulsions can generally be used in latex products in the pharmaceutical industry and agricultural fruit preservation, etc., while high-concentration wax emulsions can generally be used in papermaking sizing agent coating agents, concrete curing agents, ink dispersants, leather finishing agents , automotive and floor brighteners and wood-based panel waterproofing agents and other fields. ...
