Description

Technical Field

[0001] The utility model relates to the technical field of water-based resins, in particular to a production device for producing water-based resins using a two-step method. Background Art

[0002] Water-based resins can be widely used in coatings, adhesives, fabric coatings and finishing agents, leather finishing agents, paper surface treatment agents and fiber surface treatment agents. The two-step method is a commonly used method for synthesizing water-based resins, which usually includes prepolymer preparation (first step) and emulsification or dispersion (second step).

[0003] In the prior art, for example, Chinese patent publication number CN215506647U discloses a two-step production device for producing water-based resin, which includes a reactor, an emulsifying reactor and a feed pipe. The reactor and the emulsifying reactor are connected through the feed pipe. An emulsifier is provided in the emulsifying reactor, and an insulation mechanism is provided outside the feed pipe. The insulation mechanism includes a fixed cylinder and insulation cotton. The fixed cylinder includes a wrapping tube. The insulation cotton is located between the wrapping tube and the feed pipe. The insulation cotton and the feed pipe are relatively fixed by the fixed cylinder. The insulation mechanism has an insulation effect on the feed pipe, so that the coating is not easily affected by the external temperature when flowing through the feed pipe, resulting in cooling and condensation, which has the effect of improving the smoothness of liquid circulation in the feed pipe.

[0004] In the prior art, the raw materials need to be fully stirred and mixed uniformly when entering the reactor. However, the stirring device in the above-mentioned equipment cannot stir the raw materials near the discharge port of the reactor, resulting in the raw materials at the discharge port being sent to the emulsification reactor without being stirred uniformly, affecting the next step of emulsification processing and making it difficult to meet efficient production needs. In view of this, we propose a two-step production device for producing water-based resins. Utility Model Content
