Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a reaction kettle for preparing waterborne epoxy resin cement-based slurry. Background Art

[0002] Epoxy resin is a high molecular polymer, which is the condensation product of epichlorohydrin and bisphenol A or polyol. Epoxy resin is used in a large proportion of coatings. It can be made into varieties with different characteristics and uses. It has excellent chemical resistance, especially alkali resistance. When preparing epoxy resin, it needs to be mixed and stirred by multiple raw materials, so a reactor is needed to stir the raw materials.

[0003] By comparing with the reaction kettle for epoxy resin with patent announcement number CN216935999U, in this scheme, after the scraper in the device mixes and stirs the raw materials of epoxy resin, due to the viscosity of epoxy resin, the epoxy resin may adhere to the surface when the scraper is stirring. Therefore, after the scraper has been stirring for a long time, the epoxy resin on the surface is accumulated here, which is not conducive to cleaning the deposits on the scraper surface, and solidification may occur, which may affect the later production of epoxy resin, and there are certain limitations.
