Polyester synthesis reactor

Abstract

The invention belongs to the technical field of chemical synthesis equipment and particularly relates to a polyester synthesis reactor. The reactor comprises a reactor body, wherein the reactor body comprises an inner wall and an outer wall, the inner wall is made of elastic rubber, a jacket layer is formed between the inner wall and the outer wall, a high-temperature heat conducting agent is conveyed in the jacket layer, a cooling coil is arranged in the inner wall, a motor is arranged at the top of the reactor body and drives a rotary shaft to rotate, one side of the rotary shaft is connected with a wall scraping device, and the wall scraping device comprises a first air bag, a first magnet, a second air bag and a second magnet; the first and second air bags are communicated with an aeration head arranged at the bottom of the reactor body, and an exhaust pipe end arranged at the upper part of the reactor body is connected with a solenoid valve. Adhered materials on the inner wall arescraped by the wall scraping device, on one hand, non-uniformity of the temperature of the materials is avoided, and on the other hand, the inner wall made of the elastic rubber is shaken, so that the material mixing efficiency is improved.

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 ...
