A kind of reaction kettle for waterborne polyurethane resin

Abstract

The invention provides a reaction kettle for waterborne polyurethane resin. The reaction kettle comprises a kettle body and a stirring mechanism arranged in the kettle body, wherein a plurality of ring-shaped division plates are arranged in the kettle body to divide a cavity in the kettle body into a plurality of grooves; and the stirring mechanism comprises an upper seat and a plurality of stirring shafts connected to the upper seat, the upper seat comprises a plurality of ring bodies, the bottom surfaces of the ring bodies are connected with the stirring shafts, and the stirring shafts extend downward into the grooves corresponding to the ring bodies. According to the reaction kettle for the waterborne polyurethane resin, the division plates are arranged in the kettle body to divide the cavity in the kettle body into a plurality of grooves, and the stirring shafts of the reaction kettle rotate for stirring in the grooves to ensure that the waterborne polyurethane resin in the kettle body rotates in the grooves and radiates heat through the partition plates. Because the waterborne polyurethane resin in the kettle body contacts with the division plate in each groove, the heat radiating area of the waterborne polyurethane is effectively expanded, and the heat radiating performance of the reaction kettle is improved.

Description

technical field [0001] The invention belongs to the field of chemical equipment, and in particular relates to a reaction kettle for waterborne polyurethane resin. Background technique [0002] Reactors are generally used in the production of polyurethane resin products. The traditional reactor stirrer itself is a whole piece of solid stainless steel, which is directly placed in the reactor and stirred to complete the material mixing process. Usually in polyurethane resin synthesis reaction, viscosity will increase with reaction time. In the case of high viscosity, the physical action of stirring will also increase the temperature of the material. The traditional cooling method is to use the jacket of the reactor itself to cool through the heat transfer medium. The speed is slower like this, thereby the operating time is also forced to be lengthened, the effect is not very satisfactory, and affects work efficiency. Therefore urgently need to improve the existing reaction ...
