Problems solved by technology

However, the strength of the PTFE coating is relatively poor, and it is easy to fall off and damage. The method of adding nano-silver to the Teflon coating in the above-mentioned patent results in low strength of the Teflon resin under external force, and it is easy to fall off, which is easy to cause Damage to the nano-silver coating; at the same time, once the non-stick coating falls off, the non-stick performance of the pan is drastically reduced
In addition, the heating uniformity and antibacterial properties of the above-mentioned pots need to be improved, and the surface of the pots is not cleaned, which is easy to breed bacteria or mildew
[0004] In the prior art, ceramic pots specially used for making soup are also popular, but there is a problem that it is easy to crack under high temperature

Abstract

The invention relates to a porcelain pot which comprises a pot main body and a composite ceramic layer arranged in the pot main body, wherein a plurality of convex hulls are arranged on the upper surface of the bottom of the composite ceramic layer at intervals, the material of the composite ceramic layer comprises the following components in parts by weight: 25 to 35 parts of zirconium oxide, 50 to 70 parts of aluminium oxide, 2 to 15 parts of cerium oxide, 5 to 10 parts of copper oxide, 4 to 12 parts of steel fiber, 1 to 5 parts of carboxymethylcellulose, 2 to 6 parts of zinc sulfate, 2 to 6 parts of zinc chloride, 2 to 6 parts of sodium silicate, 2 to 6 parts of sodium metaaluminate, 0.5 to 1.5 part of silicon carbide, 0.5 to 1.5 part of iron sesquioxide, and 20 to 30 parts of deionized water. The invention further relates to a preparation method of the porcelain pot. According to the pot provided by the invention, the steel fiber with a Ni-p alloy coating is added into the composite ceramic layer, and the Ni-p alloy coating is of hyperphosphate amorphous microstructure taking Ni3P as a matrix, and has a better dispersion strengthening effect. Therefore, the binding strength of the steel fiber and the ceramic material is enhanced, and the hardness of the composite ceramic layer is improved.

Description

technical field [0001] The invention relates to the technical field of kitchen utensils, in particular to a ceramic pot and a preparation method thereof. Background technique [0002] For a long time, most of the household pots used by people are aluminum pots or iron pots. Generally, the metal sheet is blanked first, and then the metal sheet is molded into a pot body, and the outer surface of the pot body is coated with a high-temperature resistant coating. According to the use requirements of different types of pots, different types of functional materials are coated on the inner surface of the pot body to realize the use requirements of different types of pots. Among them, the heat distribution of the aluminum pan is better, but it is not easy to clean, and the oil fume is larger when the oil is used for a long time; It is easy to produce burnt paste, which increases the difficulty of cleaning the pot. [0003] At present, the common pans on the market are all non-stick...
