Problems solved by technology

Although the combination device uses the polymerization reactor and the twin-screw mixer in combination, it is still a simple separate connection, and the connection is still only connected by pipelines; when preparing polymers with high viscosity, the pipeline transmission is still relatively large. lead to production difficulties

Abstract

The invention relates to a screw extrusion-kettle type stirred combined reactor and application thereof. The screw extrusion-kettle type stirred combined reactor comprises a reaction kettle, a first screw extruder and a second screw extruder. The first screw extruder is connected with a feed inlet of the reaction kettle, and the second screw extruder is connected with a discharge outlet of the reaction kettle; the reaction kettle is provided with a stirring motor, the stirring motor is provided with a stirring shaft, and the stirring shaft is provided with stirring blades; a conveying screw isarranged at the bottom of the reaction kettle and is connected with the stirring shaft, so that the stirring shaft can rotate to drive the conveying screw to rotate. The screw extrusion-kettle type stirred combined reactor and the application have the advantages that long reaction residence time can be provided by the screw extrusion-kettle type stirred combined reactor to chemically modifying high-viscosity resin, and accordingly good modification effects such as high graft ratios can be realized by the aid of the screw extrusion-kettle type stirred combined reactor.

Description

technical field [0001] The invention relates to a screw extruding-kettle type stirring combined reactor and its application, which is suitable for the modification reaction and polymerization reaction of polymer compounds in a high-viscosity viscous flow state at high temperature, and belongs to the technical field of chemical equipment. Background technique [0002] Polymer processing, modification, and most bulk polymerization processes are often in a high-viscosity viscous flow state. At the same time, most of them need to form a suitable product shape at room temperature after the melting process, such as pellets or flakes. The equipment used in this process is mainly a screw-type extruder at present, but the disadvantage of simply using a screw-type extruder is that the residence time of the material in the screw barrel is relatively short. In some cases, it is hoped that the material has a longer residence time to improve the reaction efficiency, such as the grafting ...
