The application of wax emulsion is widely used in leather industry, construction industry, agriculture, paper industry, wood-based panel, wood waterproofing, light industry / rubber industry, ceramic industry, petroleum industry, textile industry, mold release agent, water-based paint and Water-based ink industry, then, for its preparation method, do you really know?
Here, Xiaobian to share the wax emulsion is not secretive preparation method:
The wax and the surfactant are heated to the temperature above the melting point, so that all the material is melted;
Stirring speed is generally 300 ~ 5000r / min, so that the system is completely transparent, which is completely at the molecular level of wax;
3, emulsified W / O system
The boiling water of the deionized water slowly added to the above system, the initial phase of water mass fraction of 25%, to be formed viscous paste, stirring, the formation of particles as small as possible W / O-type paste;
4, emulsified O / W system
Slowly cooled to 60 ° C, then added with ammonia-containing deionized water, and stirred to convert it into an O / W type dispersion. The addition of ammonia is to make the wax emulsion hydrophilic.
