Embodiment 1

[0017] A non-stick, wear-resistant and high-temperature resistant coating, the weight of each component is:

[0018] 32 parts of silica sol, 28 parts of alumina sol, 16 parts of nano zirconium dioxide, 4 parts of polyacrylate, 8 parts of pigments, 3 parts of fluorosilane, 15 parts of water.

[0019] The preparation method includes the following steps:

[0020] The above-mentioned silica sol, alumina sol, nano-zirconia, pigment, and water are mixed in the stated proportions, and the mixture is sealed and mixed for 5 hours at a temperature of 36°C and 230 rpm until there are no sediments; then added according to the above proportions Polyacrylate and fluorosilane are sealed and mixed and stirred at 25° C. and 150 rpm for 0.5 h to obtain the non-stick, wear-resistant and high-temperature resistant coating of the present invention.

Embodiment 2

[0022] A non-stick, wear-resistant and high-temperature resistant coating, the weight of each component is:

[0023] 30 parts of silica sol, 25 parts of alumina sol, 10 parts each of nano zirconium dioxide and nano silicon carbide, 2 parts each of polyacrylate and polydimethylsiloxane, 10 parts of pigment, 3 parts of fluorosilane, 10 parts of water Copies.

[0024] The preparation method includes the following steps:

[0025] The above-mentioned silica sol, alumina sol, nano-zirconia, nano-silicon carbide, pigment, and water are mixed first in the stated proportions, and the mixture is sealed and mixed at 35°C and 200 rpm for 3 hours until there is no sediment; then Polyacrylate, polydimethylsiloxane, and fluorosilane are added in the above proportions, and the non-stick, wear-resistant and high-temperature resistant coatings of the present invention can be obtained by airtight mixing and stirring at 20° C. and 120 rpm for 0.3 hours.

Embodiment 3

[0027] A non-stick, wear-resistant and high-temperature resistant coating, the weight of each component is:

[0028] 25 parts of silica sol, 20 parts of alumina sol, 20 parts of nano silicon carbide, 5 parts of polydimethylsiloxane, 7 parts of pigment, 5 parts of fluorosilane, 12 parts of water.

[0029] The preparation method includes the following steps:

[0030] Mix the above silica sol, alumina sol, nano silicon carbide, pigment, and water according to the stated proportions, and mix and stir for 4 hours at 30°C and 250 rpm to ensure that there is no sediment; then add the polymer according to the above proportions. Dimethylsiloxane and fluorosilane are mixed and stirred in an airtight manner at 27° C. and 140 rpm for 0.4 hours to obtain the non-stick, wear-resistant and high-temperature resistant coating of the present invention.

Abstract

The invention relates to a paint, particularly a non-sticking wear-resistant high-temperature-resistant paint and a preparation method thereof, belonging to the technical field of paints. The paint is suitable for aluminum alloys, stainless steel, cold-rolled plates, bronze/brass, glass, ceramic articles and other spray substrates. The non-sticking wear-resistant high-temperature-resistant paint is composed of the following components in parts by weight: 25-35 parts of silica sol, 20-30 parts of aluminum oxide sol, 10-20 parts of filler, 3-6 parts of assistant, 5-10 parts of pigment, 2-5 parts of fluorosilane and 10-15 parts of water. The preparation method comprises the following steps: proportionally mixing the silica sol, aluminum oxide sol, filler, pigment and water, and stirring at 25-42 DEG C at 150-250 rpm in a sealed environment for 3-5 hours until no sediment exists; and proportionally adding the assistant and fluorosilane, and stirring at 20-35 DEG C at 120-150 rpm in a closed environment for 0.2-0.5 hour to obtain the non-sticking wear-resistant high-temperature-resistant paint.

Description

Technical field [0001] The invention relates to a coating, in particular to a non-stick, wear-resistant and high-temperature resistant coating and a preparation method thereof, belonging to the technical field of coatings. Background technique [0002] At present, people have been using 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 perf...
