Problems solved by technology

Stainless steel parts such as stainless steel hoods and cooker panels in kitchen appliances need to be cleaned frequently. If the corners and other parts that cannot be cleaned will solidify and form heavy dirt after a period of time, it will be more difficult to clean and affect the user experience.
[0003] The special cleaners on the market all have strong acidity and alkalinity, which have a certain corrosive effect on the surface of the product, and will also cause certain damage to the skin health.
[0004] At present, surface treatment technologies that are hydrophilic, hydrophobic, or on the same plane with hydrophilic and hydrophobic properties have also appeared on the market. It is inevitable that the entire surface of electrical appliances will be stained with oil. The above-mentioned various surfaces are also difficult to clean the solidified oil.

Embodiment 1

[0029] Such as Figure 1-3 As shown, the present embodiment provides a substrate surface treatment method, which includes steps:

[0030] S1: Evenly apply the hydrophobic coating on the surface of the clean substrate 1;

[0031] Specifically, first, use a cleaning agent to decontaminate the surface of the substrate 1 to be treated, for example, wipe with 99% alcohol, to remove the stains on the surface of the substrate 1 to be treated, and avoid affecting the hydrophobic coating due to dust and stains The film-forming effect and the smoothness after film-forming. Then, the hydrophobic coating is uniformly coated on the surface of the decontaminated substrate 1 .

[0032] S2: the hydrophobic coating on the surface of the substrate 1 is dried to form a film-like hydrophobic coating 2;

[0033] Specifically, in step S1, the hydrophobic coating is preferably a colored or colorless hydrophobic nano-coating that can dry at room temperature. After the hydrophobic nano-coating is c...

Embodiment 2

[0048] The difference between this embodiment and Example 1 is that the solid content and / or viscosity of the nano-hydrophilic coating (coating 4 cups) are different, and the size and / or water contact angle of the formed hydrophilic raised structure 3 are different .

[0049] In the embodiment, the electrostatic voltage of the high-pressure airless electrostatic spraying equipment is 65KV, the atomization air pressure is 0.5Mpa, and the spray air pressure of the nano-hydrophilic coating is 0.4Mpa. The solid content of the nano-hydrophilic coating is 11.5%, and the viscosity (coated with 4 cups) is 29s. When the spraying time is 2s, the water contact angle of the hydrophilic raised structure 3 is 145 degrees; when the spraying time is 3s, the water contact angle of the hydrophilic raised structure 3 is 158 degrees; when the spraying time is 4s, the hydrophilic raised structure 3 The water contact angle of the water protruding structure 3 is 163 degrees; when the spraying time ...

Embodiment 3

[0051] The difference between this embodiment and Example 1 is that the solid content and / or viscosity of the nano-hydrophilic coating (coating 4 cups) are different, and the size and / or water contact angle of the formed hydrophilic raised structure 3 are different .

[0052] In the embodiment, the electrostatic voltage of the high-pressure airless electrostatic spraying equipment is 65KV, the atomization air pressure is 0.5Mpa, and the spray air pressure of the nano-hydrophilic coating is 0.4Mpa. The solid content of the nano-hydrophilic coating is 11.5%, and the viscosity (coated with 4 cups) is 30s. When the spraying time is 2s, the water contact angle of the hydrophilic raised structure 3 is 141 degrees; when the spraying time is 3s, the water contact angle of the hydrophilic raised structure 3 is 155 degrees; when the spraying time is 4s, the hydrophilic raised structure 3 The water contact angle of the water protruding structure 3 is 162 degrees; when the spraying time ...

Abstract

The invention discloses a base material surface treatment method. The method comprises the steps that S1, the surface of a clean base material is evenly coated with a hydrophobic paint; S2, the hydrophobic paint on the surface of the base material is dried to form a film-like hydrophobic coating; S3, residues on the surface of the hydrophobic coating are removed; S4, high-pressure airless electrostatic spraying equipment is adopted for uniformly spraying hydrophilic paint to the surface of the hydrophobic coating; and S5, the hydrophilic paint on the surface of the hydrophobic coating is driedto form a plurality of hydrophilic bulge structures which are arranged at intervals. The micron-sized concave-convex structure is formed on the surface of the base material, the super-hydrophilic andsuper-hydrophobic principle is utilized, so that the surface of the treated base material is not prone to adhesion, even if the surface of the treated base material is adhered, oil stain air bubblescan be formed in concave positions of the concave-convex structure, the adhesion area of oil stain and the surface of the treated base material is reduced, the effect that no cleaning agent is used, and the oil stain can be easily removed only through wet cloth is achieved, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of substrate surface treatment, in particular to a substrate surface treatment method for kitchen appliances. Background technique [0002] In daily life, household and restaurant kitchens are faced with the problem of heavy oil pollution and difficulty in cleaning, especially the Chinese people like to stir-fry, and this problem is particularly prominent. Stainless steel parts such as stainless steel hoods and cooker panels in kitchen appliances need to be cleaned frequently. If the corners and other parts that cannot be cleaned will solidify and form heavy dirt after a period of time, it will be more difficult to clean and affect the user experience. [0003] The special cleaners on the market all have strong acidity and alkalinity, which have a certain corrosive effect on the product surface, and will also cause certain damage to skin health. [0004] At present, surface treatment technologies that are h...
