The invention belongs to the technical field of chemical synthesis equipment, and specifically relates to a reaction kettle for polyester synthesis, including a kettle body, the kettle body including an inner wall and an outer wall, the inner wall is made of elastic rubber, and the A jacket layer is formed between the inner wall and the outer wall, and a high-temperature heat-conducting agent is conveyed in the jacket layer, a cooling coil is arranged in the inner wall, and a motor is installed on the top of the kettle body, and the motor drives The rotating shaft rotates, and a wall scraping device is connected to one side of the rotating shaft, and the wall scraping device includes a first air bag, a first magnet, a second air bag and a second magnet; The gas head is connected, and the end of the exhaust pipe arranged on the upper part of the kettle body is connected with a solenoid valve. The invention scrapes off the adhered material on the inner wall through the wall scraping device, on the one hand avoids the temperature unevenness of the material, on the other hand shakes the inner wall layer made of elastic rubber, thereby improving the mixing efficiency of the material.
Description
technical field [0001] The invention belongs to the technical field of chemical synthesis equipment, in particular to a polyester synthesis reaction kettle. Background technique [0002] Polyester resins are divided into saturated polyesters and unsaturated polyesters. Unsaturated polyester can be used to prepare polyester adhesive, which is mainly composed of unsaturated polyester resin, initiator, accelerator, filler, thixotropic agent and so on. A linear structure (see linear polymer) polyester resin containing -CH=CH- double bonds in the main chain, which can be mixed with ethylenic monomers, such as styrene, acrylate, vinyl acetate, etc., in the Under the action of initiators and accelerators, it can be polymerized into insoluble and infusible products at room temperature, and is mainly used in the production of coil coatings. Saturated polyester resins are mainly used as film-forming substances for powder coatings, and the market is extremely broad. [0003] In the ...
