Embodiment 1

[0040] Metal surface micro-arc oxidation ceramic pot, the preparation method is:

[0041] (1) Degreasing: Use M600# and M800# sandpaper to polish the surface to be micro-arc oxidized of the magnesium alloy pan body. The surface to be micro-arc oxidation is soaked and scrubbed. Under normal temperature conditions, the soaking time is 5 minutes, and the oil on the surface is removed to obtain the oil-free surface A to be micro-arc oxidation;

[0042] (2) Preparation of micro-arc oxidation solution: add 5 grams of dimethyl sulfoxide, 1 gram of potassium hydroxide, 0.5 grams of ammonium chloride, 0.1 grams of citric acid, 0.5 grams of barium carbonate, 1 grams of Zinc oxide and 5 grams of sulfonated polyphosphazene-polyvinyl alcohol-nanometer hydroxyapatite composites are fully dissolved to obtain a micro-arc oxidation solution, which is then added to the main micro-arc oxidation tank;

[0043] The sulfonated polyphosphazene-polyvinyl alcohol-nano hydroxyapatite composite is prep...

Abstract

The invention discloses a metal surface micro-arc oxidation ceramic pot which comprises a metal alloy pot base body and ceramic film layers arranged on the inner and outer surfaces of the base body through micro-arc oxidation. The ceramic film layers are prepared from, by weight, 5-10 parts of dimethyl sulfoxide, 1-2 parts of potassium hydroxide, 0.5-1 part of ammonium chloride, 0.1-1 part of citric acid, 0.5-1 part of barium carbonate, 1-2 parts of zinc oxide, 5-10 parts of sulfonated polyphosphazene-polyvinyl alcohol-nano-hydroxyapatite composite and 100 parts of water. The ceramic pot has higher heat resistance and lower heat expansion coefficients, and existing problems are solved.

Description

technical field [0001] The invention belongs to the technical field of pots, and more specifically relates to a ceramic pot with metal surface micro-arc oxidation and a preparation method thereof. Background technique [0002] Pots are the most commonly used cooking utensils, but because they are used under high temperature and rapid cooling and rapid heating, the material of frying pans is generally all iron so far. However, the iron frying pan has poor heat preservation performance, and the cooking taste is not delicious; and it is easy to rust, and long-term use will cause harm to the human liver. For this reason, the prior art also has some organic coatings sprayed on the surface of the pot to prevent rust, but the use effect is not good, and it will inevitably cause secondary pollution. For this reason, prior art has developed ceramic pan gradually, and it has good thermal insulation performance, cooking taste is delicious, and environmental protection, corrosion resis...
