Description

Technical Field

[0001] The utility model relates to the technical field of waterborne acrylic emulsion, in particular to a processing and storage device for waterborne acrylic emulsion. Background Technique

[0002] Waterborne acrylic emulsion is a milky white or nearly transparent viscous liquid copolymerized from pure acrylate monomers. It has small particle size, multiple uses and excellent performance, and is suitable for a variety of coating formulations, especially performing well in high-gloss and semi-gloss coatings. It is widely used due to its excellent water resistance, weather resistance, alkali resistance, stain resistance and good adhesion to the surfaces of masonry, wood and steel. In addition, it can not only be used to prepare flat, semi-gloss and high-gloss latex paints, but also be used for the finishing coatings of high-quality floors, colored cement tiles and tennis courts. However, waterborne acrylic emulsion is prone to volatilization during storage. After retrieval, the patent with the publication number CN217075657U discloses a storage device for the production of waterborne acrylic emulsion, in which both the feed inlet and the discharge outlet are arranged at the bottom of the tank body, and waterborne acrylic emulsion is added by pressurizing from the bottom. Over time, it is easy to act on the pressure pump in the opposite direction, resulting in easy cracking at the connection between the pressure pump and the bottom of the tank body. Moreover, with the progress of feeding, the energy consumption of the pressure pump will be more and more. Therefore, it is necessary to design a processing and storage device for waterborne acrylic emulsion that is easy to seal and store, reduces volatilization, maintains a stable and low energy consumption during the filling process, avoids the situation that the pressure on the filling mechanism becomes larger and larger as the filling liquid level rises, resulting in easy cracking, and has high use stability.
