Problems solved by technology

[0002] Pot is an indispensable household appliance in people's daily life. In the prior art, it is generally made of cast iron, but it has the advantages of large weight, small heat resistance range, large thermal expansion coefficient, small thermal diffusivity and thermal conductivity. Disadvantages; there are also pots made of ceramics. Although porcelain pots have high thermal conductivity and small thermal expansion coefficient, their heat-resistant range is small, and they can only be heated with open flames and are easy to break; at the same time, there are so-called pots made of high borosilicate Health pot, although it has a low coefficient of thermal expansion, it is not sensitive to heat

Abstract

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.
