The present invention relates to a stockpot, and belongs to the technical field of pots. According to the stockpot, a pot body is prepared by a graphite composite material, and a non-stick layer is coated to an internal surface of the pot. The graphite composite material comprises 1-3% of glass fibre, 5-10% of talcum powder, 0.3-2% of aluminum powder, 0.1-0.5% of titanium powder, 0.5-2% of magnesium oxide, 0.5-2% of silicon nitride, 0.5-3% of calcium carbonate and 30-50% of ceramic clay, the balance being graphite. The stockpot is prepared by the graphite composite material with reasonable compatibility. The prepared stockpot has light weight, a large heat-resisting range, a small thermal expansion coefficient, high thermal diffusivity and thermal conductivity and rapid heat transfer, andis heated uniformly. Furthermore, acrylic acid is added to the coating of the non-stick layer, so that the gap of molten resin particles can be tensioned by the capillary effect generated due to the fact that the surface coating is volatilized away when sintered to form a film, high-temperature degradation of a little PTFE is suppressed, and therefore yellow stain of the surface coating is reduced.
