Description

Metal appliances with anti-scratch and hydrophobic effect

An aluminum appliance, particularly a metal appliance with anti-scratch and hydrophobic effect.

In order to make the product more durable and prolong its service life, the industry will apply a scratch-resistant and abrasion-resistant coating on the surface of the product. For example, in order to achieve non-sticking, avoid rusting of metal, or scratch the surface of the object during repeated use, Damage and other purposes, usually the surface of the object is coated with non-stick, rust or scratch-resistant coating.

At present, technologies have been developed to generate coatings using plasma. Most of them use low-pressure vacuum coating processes, but the scratch resistance and hydrophobicity of the coatings produced are generally poor, and the manufacturing cost of low-pressure plasma is high, and low pressure is generated by evacuating. Status is extremely time consuming.

In addition, the coating film of the aforementioned low-pressure vacuum coating process has not only poor scratch resistance and hydrophobicity, but also has less flexibility. It is easy to crack or crack after bending. Most of them can only be used for glass or metal. The flexible hard substrate is relatively inapplicable, so it is necessary to develop another coating structure to improve the defects of the existing technology.

In order to solve the disadvantages of the current low-pressure vacuum coating process and the poor scratch resistance and hydrophobicity of the plating layer and the lack of flexibility, the present invention provides a metal appliance with an anti-scratch and hydrophobic effect, which includes a layer of: a metal layer; A scratch-resistant hydrophobic layer is laminated on at least a part of the surface of the metal layer; wherein: the scratch-resistant hydrophobic layer is deposited on the surface of the metal layer by using atmospheric atmospheric low-temperature plasma.

The metal layer is a metal kitchen utensil made of aluminum or a metal utensil used for holding food.

The scratch-resistant hydrophobic layer includes a monomer in a solution state and / or an organic carbon-containing silane gas.

Wherein, the organic carbon-containing silane gas or liquid further includes oxygen as the organic carbon-containing siloxane gas or liquid.

The monomer in the solution state includes a solution formed by a fluorine solvent and a perfluoropolyether silicon compound.

The organic carbon-containing silane gas includes tetramethyldisilazane gas.

From the above description, the new model has the following advantages:

1. This new type uses atmospheric atmospheric pressure low temperature plasma for surface treatment and plating, so that the deposited anti-scratch hydrophobic layer can be firmly attached to the surface of the object, and it is not easy to be scraped or damaged, and this new type uses atmospheric atmospheric low temperature plasma. The plating technology can greatly reduce the manufacturing cost, so it overcomes the lack of conventional technology.

2. The new type controls the chemical composition of the anti-scratch hydrophobic layer, so that it can produce a tight organic chemical bond during deposition, so that the anti-scratch hydrophobic layer has flexibility characteristics, and it is not easy to generate cracks or cracks due to bending or bending. Increase the scope of application of this new type.

Please refer to FIG. 1, the present invention provides a metal appliance with anti-scratch and hydrophobic effect, which includes a metal layer M; and a scratch-resistant hydrophobic layer L, which is laminated on at least a part of the surface of the metal layer M. The metal layer M is preferably in contact with the metal utensils and food materials, such as the scratch-resistant hydrophobic layer L laminated on the inner surface of the cookware shown in Figs. 2a and 2b. The metal layer M is preferably an aluminum metal Utensils, such as kitchen utensils (such as the cooking pot shown in Figure 2a or the pan shown in Figure 2b), such as kitchen metal utensils used for baking, roasting, frying, frying, and cooking, and food holding or holding Metal appliances.

In the novel method for plating the scratch-resistant hydrophobic layer L on the surface of the metal layer M, an ordinary piezoelectric paste plating method is preferably used. The steps include:

Plasma pretreatment: A metal layer M is subjected to surface pretreatment with atmospheric pressure cold plasma. The plasma used for pretreatment is to pass in 0.11-10 MPa compressed air, the distance from the plasma head to the surface of the object is 0.1-10 cm, and the moving speed of the surface of the object relative to the plasma head is ≧ 0.01 cm / s , The working time is ≧ 1 s, the power is 5-5000 watts, and the frequency is 5-5000 kHz.

Deposition of a scratch-resistant hydrophobic layer: The metal layer M, which has been pretreated by atmospheric atmospheric low-temperature plasma, is also deposited on the surface of the metal layer M in the form of atmospheric atmospheric low-temperature plasma. The deposition method provided by the present invention is preferably to first pass a compressed (high pressure) air into a plasma head, and the compressed air passing through the plasma head often generates a plasma jet from a piezoelectric plasma source, and At the same time, an organic fluorine-containing gas or liquid (preferably in a solution state) and / or an organic carbon-containing silane gas or liquid and a mixture of nitrogen are passed in, so that the scratch-resistant hydrophobic layer L is formed on the metal layer. M. The compressed air is preferably removed from the humidity in the air and then passed into the plasma head, so as to prevent the moisture and water from reacting with the monomer or gas that is subsequently deposited to affect the deposition effect.

Post-treatment of atmospheric low-temperature low-temperature plasma: The metal layer M having the anti-scratch hydrophobic layer L deposited thereon is post-processed using atmospheric atmospheric low-temperature plasma. The post-processing includes passing in the compressed air of 0.11-10 MPa, the distance from the plasma head to the surface of the object is 0.1-10 cm, the moving speed of the surface of the object relative to the plasma head is ≧ 0.01 cm / s, and The time is ≧ 1 s, the power is 5-5000 watts, and the frequency is 5-5000 kHz. This atmospheric and atmospheric low-temperature plasma treatment can also be changed to oven baking and post-treatment. The parameters of oven baking include temperature ≧ 50 ^o C and time ≧ 0.5 minutes.

In addition to the aforementioned organic carbon-containing silane gas or liquid, the material of the new scratch-resistant hydrophobic layer L may further include oxygen to form an organic carbon-containing siloxane gas or liquid. A preferred embodiment may be, for example, tetramethyl Tetramethyldisiloxane (TMDSO); and the organic fluorine-containing gas or liquid may preferably be an organic fluorine-containing gaseous monomer or a solution-state monomer (F-containing liquid solution), such as a fluorine solvent and a perfluoropolymer A solution formed by an ether silicon compound; the new type can deposit an organic carbon-containing silane gas as the scratch-resistant hydrophobic layer L on the metal layer M, and can simultaneously deposit an organic fluorine-containing gas or liquid and an organic carbon-containing silane Gas or liquid is deposited on the metal layer M together to achieve better hydrophobicity.

The new plasma treatment temperature used in the atmospheric atmospheric low-temperature low-temperature plasma pretreatment step and the step of depositing the anti-scratch hydrophobic layer is based on the atmospheric atmospheric low-temperature process, which maintains the high adhesion of the deposited anti-scratch hydrophobic layer and is not easy to fall off or scratch. In addition to its efficacy, it is also relatively energy efficient. In addition, the scratch-resistant hydrophobic layer L formed by the present invention has a flexible property because it generates a chemical bonding component, and can not generate cracks or cracks as the metal layer M is bent or bent. It is suitable for kitchen appliances, such as Metal kitchen utensils made of aluminum or metal utensils for food holding.
