Abstract
Continuous production equipment for graphene composite material includes a raw material preparation device; a reaction device, a material discharge end of the raw material preparation device being connected to the reaction device; and an extraction device configured to extract and purify crude composite material obtained from the reaction device, a material feed end of the extraction device being connected to the material discharge end of the reaction device, and a material discharge end of the extraction device being configured to convey polyamide monomer extract obtained by extraction to a liquid conveying pipe of the raw material preparation device. The raw material preparation device includes a raw material melting kettle configured to melt polyamide monomer and mix the molten polyamide monomer with graphene, and the raw material melting kettle is provided with a high-shear emulsifying machine and an ultrasonic disperser.
