Technical Field

[0001] The utility model relates to the technical field of reaction kettles, and more specifically to a polyurethane resin reaction kettle. Background Art

[0002] As a polymer material with high strength, tear resistance, wear resistance and other properties, water-based polyurethane resin is still a representative of excellent resins and one of the hot spots in modern water-based resin research. The resin is usually reacted in a reactor. The resin synthesis process in the reactor is heated by water vapor or warm water. When heated to a certain temperature, it is quickly cooled by circulating cold water, and auxiliary stirring is performed by a stirring shaft.

[0003] At present, the cooling structure used on the polyurethane resin reactor generally uses a condenser and cold water to cool the entire reactor. However, there are still some problems with this structural setting. The condenser is usually wound around the outer wall in a ring shape, which will leave a certain gap, resulting in an incomplete cooling range and failure to contact the bottom of the reactor, affecting the cooling effect at the bottom. Therefore, the time required for cooling will be increased, resulting in a waste of time and affecting the overall use effect. Utility Model Content
