Description

Technical Field

[0001] The utility model relates to the field of polymer emulsion production devices, in particular to a polymer emulsion continuous production device. Background Art

[0002] Polymer emulsion is an emulsion-like polymer obtained by emulsion polymerization or emulsion copolymerization. The polymer particles are stably dispersed in the dispersion medium under the action of an emulsifier. According to the dispersion medium, it can be divided into water-based and oil-based. The outstanding advantage of water-based emulsion polymer is that it is environmentally friendly and can be used as adhesives, paints, coatings, and can be used in the textile, papermaking and construction industries.
