The utility model discloses a solid epoxy resin reaction kettle in a two-step method. The solid epoxy resin reaction kettle consists of a kettle body, a stirrer transmission device, a stirring shaft and a stirring paddle, and is characterized in that the stirring shaft consists of a high-speed stirring shaft and a low-speed stirring shaft which are concentric to each other and are respectively driven by the stirrer transmission device; the high-speed stirring shaft is downward and vertically passes through the center of the kettle body; an inner stirring paddle is arranged on the lower part of the high-speed stirring shaft; and an outer stirring paddle is arranged on the low-speed stirring shaft and is extended to the bottom of the kettle. By adopting double-speed inner and outer stirring paddles, the solid epoxy resin reaction kettle is suitable for large viscosity change of reaction materials, and is large in size of the reaction kettle and high in production efficiency; and the product quality and the production efficiency are improved.
