Embodiment 1

[0025] The various raw materials used, including silver nitrate, aluminum nitrate and ethyl orthosilicate, are all analytically pure.

[0026] First dissolve 74 grams of silver nitrate, 1000 milliliters of distilled water, and 20 milliliters of nitric acid. Add 750 grams of aluminum nitrate to the solution, and then add 1200 milliliters of water to completely dissolve it to prepare a clear and transparent solution for use; weigh 840 grams of orthosilicic acid Then add 200 ml of water, 200 ml of absolute ethanol, and 5 ml of nitric acid to it. Stir thoroughly to obtain the hydrolyzed solution for use. The measured pH value is 2; the clear and transparent solution and the hydrolyzed solution are thoroughly mixed and stirred at a constant temperature. The solution was fully reacted for 3 hours at a temperature of 80°C and gelled. After the gelled colloid was placed in a constant temperature drying oven at 150°C, it was completely dried and then calcined in a muffle furnace at 1100°C ...

Embodiment 2

[0029] The raw materials used, including silver nitrate, aluminum nitrate and ethyl orthosilicate, are all analytically pure.

[0030] First dissolve 80 grams of silver nitrate, 1000 milliliters of distilled water, and 20 milliliters of nitric acid. Add 800 grams of aluminum nitrate to the solution, and then add 1200 milliliters of water to completely dissolve it to prepare a clear and transparent solution for later use; weigh 1000 grams of orthosilicic acid Then add 400 ml of water, 400 ml of absolute ethanol, and 7 ml of nitric acid to it. After stirring thoroughly, the hydrolyzed solution is obtained for use. The measured pH value is 1.8; the clear and transparent solution and the hydrolyzed solution are thoroughly mixed, and the The solution was fully reacted and gelled at a temperature of 70°C with a stirrer for 3 hours. After the gelled colloid was placed in a constant temperature drying oven at 200°C, it was completely dried and then calcined in a muffle furnace at 1200°C f...

Embodiment 3

[0033] First dissolve 100 grams of silver nitrate, 1000 milliliters of distilled water, and 20 milliliters of nitric acid. Add 900 grams of aluminum nitrate to the solution, and then add 800 milliliters of water to completely dissolve it to prepare a clear and transparent solution for later use; weigh 1000 grams of orthosilicic acid Then add 300 ml of water, 300 ml of absolute ethanol, and 7 ml of nitric acid to it. After stirring thoroughly, the hydrolyzed solution is obtained for use. The measured pH value is 1.6; the clear and transparent solution and the hydrolyzed solution are thoroughly mixed, and the The solution was fully reacted with a stirrer at 90°C for 2 hours and gelled. After the gelled colloid was placed in a constant temperature drying oven at 180°C for thorough drying, it was calcined in a muffle furnace at 1150°C for 3 hours to synthesize.

[0034] Then, the composite ceramic powder is added to distilled water, ball milled to form a slurry, coated on the surface ...

Abstract

The invention relates to an antibacterial ceramic coating of a non-stick pan, a preparation method and a non-stick pan thereof. The antibacterial ceramic coating comprises the following components: silver, aluminum oxide and silica, wherein the weight ratio of the silver to the aluminum oxide to the silica is 4.4-6.5: 10-13: 22-30. The preparation method comprises the following steps of: by taking absolute ethyl alcohol as a co-flux and adding acid liquor as a catalyst, forming silica sol through hydrolysis and polycondensation of alkoxysilane, uniformly dispersing two reactants into gel of a silica nanometer network structure by utilizing reaction among silver nitrate, aluminum nitrate and silica, carrying out solid-phase reaction between the two reactants through high-temperature burning, and synthesizing complex phase ceramic material powder. The preparation method, provided by the invention, is scientific and reasonable, simple and easy to implement, and convenient for application, the prepared antibacterial ceramic coating has the advantages of good mechanical property, high intensity, scratch resistance, antibiosis, no toxicity and environmental friendliness, and conforms to requirements of safety, health, energy conservation, green and environmental friendliness of the current international environmental group and nation.

Description

Technical field [0001] The invention relates to a non-stick cookware, in particular to an antibacterial ceramic coating of a non-stick pan, a preparation method and a non-stick pan. Background technique [0002] For a long time, people have used traditional metal pans (cast iron, stainless steel, aluminum and aluminum alloy) to cook food, but the phenomenon of food sticking to the pan often occurs during the cooking process. This not only destroys the shape of the food, but also the food that sticks to the pot is prone to burnt, and even produces harmful substances, which affect human health. In addition, the difficulty of washing the cookware is increased, which brings inconvenience to cooking. Therefore, the non-stick pan has been popular since it was invented because it is easy to clean, can fry and fry food without sticking to the pan, can minimize oily smoke, and meet modern people's pursuit of green food, low fat, low calorie performance. Popularity. [0003] However, the ...
