Embodiment 1

[0028] 1) the trade mark that U.S. BakerHughes company produces is that vybar103 branched polyethylene wax and white oil are fully mixed to obtain mixture by the mass ratio of 100:5;

[0029] 2) Mix the mixture with the emulsifier sodium lauryl sulfate at a mass ratio of 100:10, then heat and melt at 70-95°C, slowly add hot water at 95°C, homogenize and emulsify until the emulsion is uniform to obtain an emulsion ;

[0030] 3) Cool the emulsion to 60° C., add water to adjust the solid content to 30% to obtain a wax emulsion.

Embodiment 2

[0032] 1) the trade mark that U.S. BakerHughes company produces is that vybar260 branched polyethylene wax and liquid paraffin are fully mixed to obtain mixture by the mass ratio of 100:8;

[0033] 2) Mix the mixture with the emulsifier sodium dodecylsulfonate at a mass ratio of 100:14, then heat and melt at 70-95°C, slowly add hot water at 93°C, homogenize and emulsify until the emulsion is uniform lotion;

[0034] 3) Cool the emulsion to 40° C., add water to adjust the solid content to 50% to obtain a wax emulsion.

Embodiment 3

[0036] 1) the trade mark that U.S. BakerHughes company produces is that vybar103 branched polyethylene wax and turpentine are fully mixed to obtain mixture by the mass ratio of 100:10;

Abstract

The invention discloses a method for preparing wax emulsion from branched polyethylene wax through direct emulsification, which comprises the following steps of: mixing the branched polyethylene wax and a cosolvent, adding an emulsifier and heating and emulsifying; adding water and dispersing and emulsifying by a phase transfer method; and shearing, emulsifying and dispersing to prepare milky branched polyethylene wax emulsion. In the emulsification method, the cosolvent is added into the branched polyethylene wax for direct emulsifying, and the process for production of the emulsion is greatly simplified. The branched polyethylene wax emulsion can be applied in the fields of leather finish, fur finishing, textile finishing, automobile polishing, shoe cream and the like, the coating has smooth handfeel, natural color, high hardness and high scratch resistance, and the wax emulsion is a high-grade wax emulsion product. The emulsification process can greatly expand the use of the branched polyethylene wax and reduce the application of solvent products, and is an environmentally-friendly emulsification process.

Description

technical field [0001] The invention belongs to the field of fine chemical product production, and in particular relates to a method for preparing wax emulsion by direct emulsification of branched polyethylene wax. Background technique [0002] Wax emulsion is a widely used fine chemical product. It is widely used in many industries such as coatings, papermaking, and fabric finishing. Wax emulsion can give coatings a smooth feel and a certain gloss, and fabrics have a good smoothness and Hand feeling, good gloss of paper and certain water repellency. Wax emulsions are widely used, and high-grade wax emulsions have high added value. Wax emulsion does not need to be heated and melted or dissolved in certain solvents when used. It has stable performance, fineness, uniform film formation, good coverage, and is easy to mix and compound with aqueous solutions or emulsions of other substances, and is non-toxic and non-corrosive. High performance, easy to store, easy to use and so...
