Description

Technical Field

[0001] This utility model relates to the field of epoxy resin paint preparation technology, and in particular to a reaction vessel for epoxy resin paint production. Background Technology

[0002] Epoxy resin floor paint is a particularly beautiful and long-lasting type of floor paint, mainly composed of epoxy resin and a curing agent. Because the main film-forming material of epoxy floor paint is epoxy resin, which is thermoplastic, it needs to react with a curing agent or fatty acid to crosslink and form a network structure of large molecules, changing its thermoplasticity to thermosetting properties, thus exhibiting various excellent properties.

[0003] In the production of epoxy resin paint, traditional reactors often suffer from poor material dispersion due to low stirring efficiency and uneven mixing. They also suffer from insufficient temperature control precision and high energy consumption, all of which affect product quality and production stability. Specifically, blind zones in the stirring process lead to inadequate mixing of resin and curing agent, uneven temperature distribution affects the uniformity of the polymerization reaction, and the equipment relies on external power, resulting in low energy utilization.
