Problems solved by technology

The film-forming raw materials are completely different from the current resin organic coatings, such as Teflon, silicone, polyethersulfone, etc., so the performance is quite different, and the film-forming mechanism is also different from that of enamel, so it overcomes the poor thermal shock resistance of enamel, Poor resistance to physical impact, easy to burst, few colors, difficult construction, low yield, etc.

Embodiment 1

[0022] The main steps of the embodiment of the present invention include:

[0023] (1) Pre-treatment, dehumidification and degreasing treatment of die-casting aluminum alloy cookware;

[0024] (2) Paint spraying, the spraying environment temperature is 20°C, the humidity is 70% RH, the spraying method is air spraying, the spray gun diameter is 1.0㎜, and the air pressure is 5-6 Kgf / cm2;

[0025] (3) curing, such as figure 2 As shown, the initial temperature is 60°C, gradually increase the temperature, and reach 160°C after 10 minutes, then keep baking at 160°C for 10 minutes, and finally cool down.

[0026] Before painting, use a 300-mesh or higher mesh filter to avoid particles in the paint film.

[0027] The thickness of the paint film is controlled within 15 μm, and the paint film is easy to crack if it exceeds this thickness.

[0028] During the processing, the surface of the substrate must be kept clean without any dust, oil, etc.

[0029] Step (2) After spraying the ...

Abstract

The invention discloses a nano-inorganic ceramic spraying treatment technology for die-casting aluminum alloy cookware. Various nano-scale oxides are hydrolyzed and solidified at low temperature through an improved sol-gel reaction to form a paint film similar to ceramics and glass. . The nano-inorganic ceramic coating produced by the present invention has the functions of preventing surface oxidation, insulation, antistatic, waterproof, dust-proof, high hardness, wear resistance and non-stick and self-cleaning effect. At the same time, the nano-inorganic ceramic material is a kind of ultraviolet The absorbing material has good UV resistance, which greatly improves the use effect of the cooker.

Description

technical field [0001] The invention belongs to the application field of a new surface treatment process in civil products, belongs to the application category of key surface coating technology, and specifically relates to a nano-inorganic ceramic spraying treatment technology for die-casting aluminum alloy cookware. Background technique [0002] Now the non-stick coatings used in the kitchen cookware market are all organic non-stick coatings, which are polytetrafluoroethylene (Teflon) or oily coatings. Traditional coatings are commonly known "paints". Organic coatings, most organic coatings use some raw materials that are harmful to the human body and the environment during the production process, and also emit harmful waste water and gases during the production process, and even release harmful gases for a period of time after construction. gas. However, the final layer prepared by ordinary anodic oxidation has poor wear resistance and is easy to corrode. And the nano-ce...
