[0002] Polyphenylene ether is a kind of polymer material. After foaming treatment, various types of polyphenylene ether foaming materials can be obtained. These materials have the characteristics of low density, low thermal conductivity, high sound absorption, excellent heat insulation and sound insulation, etc., and are widely used in the fields of construction, transportation, electronics, etc. The foaming of polyphenylene ether mainly adopts two methods: thermal foaming method and physical foaming method. The general understanding of a reaction kettle is a container for physical or chemical reactions, which is a pressure vessel used to complete processes such as vulcanization, nitrification, hydrogenation, alkylation, polymerization, and condensation.

[0003] Currently, when using a reaction kettle, there is a lack of an auxiliary circulation heating mechanism.

Therefore, a reaction kettle for producing modified polyphenylene ether foaming beads is proposed to facilitate the addition of an auxiliary circulation heating mechanism, improve the temperature consistency inside the reaction kettle, and improve the production environment of modified polyphenylene ether foaming beads, thereby improving the use effect.
