A polymer material emulsion polymerization reaction kettle

Abstract

The utility model relates to high polymer material technical field especially, a kind of reaction kettle for high polymer material emulsion polymerization, including, kettle body, for accommodating polymerization reaction material;Constant-temperature heating mechanism is set on the kettle body outer wall, the constant-temperature heating mechanism includes heating assembly and heat preservation component, the heating assembly is filled with heat-conducting oil;Circulating flow guide mechanism, the circulating flow guide mechanism is installed in the outside of the heat preservation component, the inlet and outlet of the circulating flow guide mechanism are located in the inside of the heat preservation component, the utility model circulates heat-conducting oil by circulating flow guide mechanism, can respond temperature fluctuation in initiator addition etc. Key stage quickly, ensure that the temperature in reaction kettle is constant, avoid the polymerization out of control caused by temperature sudden rise, electric heating rod heats in upper layer heat-conducting oil, bottom heat-conducting oil flows to heat-conducting oil upper layer by circulating flow guide mechanism, reduce the temperature difference of upper and lower layers, avoid the gelation caused by local temperature difference.
