Abstract

The invention discloses a synthetic method for an aqueous polymer emulsion, which includes the steps of: 1) mixing and emulsifying a part of a monomer, pure water and an emulsifier to obtain an emulsified liquid; 2) providing a flat flow reaction chamber, and continuously feeding the emulsified liquid therein and meanwhile continuously feeding a mixture liquid composed of the rest of the monomer and pure water into the reaction chamber to perform a polymerization reaction, wherein a product is continuously outputted from the reaction chamber. In the mode including pre-emulsification and flow reaction in the flat flow reaction chamber, raw materials are fully contacted and problems of non-uniform heating and reaction are overcome, thus achieving continuous and complete rapid reaction. The synthetic method is more safe, environment-friendly, energy-saving and high-effective.

Description

technical field [0001] The invention relates to the field of material synthesis, in particular to a method and equipment for synthesizing an aqueous polymer emulsion. Background technique [0002] The method for synthesizing water-based polymer emulsion in the prior art is to add all the reaction raw materials and auxiliary agents together in the reactor, and then provide conditions such as suitable reaction temperature to the reactor, so that the raw materials are polymerized in the reactor. Although this method can realize synthesis, because the raw materials are too concentrated, it is easy to have uneven heat transfer and uneven reaction, and it is generally intermittent production, so it is difficult to realize continuous production. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a kind of water-based polymer emulsion that can fully contact the raw materials, effectively overcome the problems of uneven heat...
