Description

  The present invention relates to a device in which an ink pigment is jetted on the surface of a one-coating layer or a three-coating layer to form a speckled coating layer, and a method for forming a coating layer applied to the device. Or, an irregular pigment-like discontinuous coating layer was formed by applying ink pigments in spots on one coating layer formed by applying either heat-resistant paint or fluororesin paint to the surface of the device. The present invention relates to a device and a method for forming a discontinuous coating layer on the device.

  Most common instruments that need to be coated on the surface are made of a metallic material such as aluminum. In the past, we used appliances made only of metal, but such appliances made only of metal were used for kitchen utensils, for cooking food and drinks, or otherwise. Problems such as scratching of the surface of the instrument occur. In order to prevent this, since various types of coating layers that have been coated with various types of coating liquids have been developed on the surface since a device was developed in which a coating liquid was applied to the surface and a coating layer was formed on the surface. The formed instrument will appear.

  Among them, a so-called three coating, in which a primer coat, a mid coat, and a top coat are sequentially laminated on the surface of the device to form a coating layer, is universal. Applied to instruments. As shown in FIG. 3, recently, one step further, with the primer coat 20 or midcoat 30 formed on the instrument 10 partially dried or wet, a different sputter ink was applied, By forming a discontinuous coat 60 composed of continuous small spheres and applying a top coat 40 thereon, the discontinuous coat expresses the three-coating layer 50 in various colors, and itself A coating layer has been developed that protrudes slightly and prevents the surface of the device from being scratched. Such appliances are typically applied to kitchen appliances.

  However, in this type of coating, the main purpose of applying the discontinuous coating to the three coating layer is to provide a device capable of color expression that is not easily obtained by reflective pigments. In the form in which the discontinuous coat is applied between the primer coat and the mid coat or between the mid cord and the top coat, the top coat completely covers the discontinuous coat, Since the surface coating layer has a substantially flat surface, there is a problem that the scratch resistance cannot be clearly exhibited.

  One coating layer which is one of a ceramic coating layer, a heat resistant coating layer or a fluororesin coating layer formed by applying any one of ceramic paint, heat resistant paint or fluororesin paint having the above composition and composition ratio The method for forming a coating layer on the surface of the device with the same or different ink pigment will be described as follows.

  First, in the first stage, the surface blasting process is performed to form countless fine embosses on the surface of the device to be coated, thereby increasing the surface area. In the second stage, the sandblasting process is performed. The surface of the device thus cleaned is cleaned thoroughly, and in the third step, a one-coating layer or a three-coating layer is formed on the surface of the device cleaned by sandblasting. That is, one paint layer selected from ceramic paint, heat-resistant paint or fluororesin paint is applied to a thickness of 15 to 25 μm, and one coating layer which is one of the ceramic coating layer, heat-resistant coating layer or fluororesin coating layer is formed. After the formation, heat treatment is performed at 100 to 150 ° C. for 10 to 15 minutes, or a primer coating solution is applied to a thickness of 10 to 12 μm to form a primer coat, and then dried at 200 ° C. for 15 minutes. Then, a mid-coating solution is applied to a thickness of 10 to 12 μm on the primer coat applied to the surface of the device to form a mid-coat, and in the fifth step, the top-coating solution 8 is added before the mid-coat is completely dried. After forming a top coat by applying to a thickness of ˜12 μm, By between drying, thus completing the three coating layers. In the next step, an ink pigment is sprayed on the dried top coat of the one-coating layer or the three-coating layer to form a spot-like irregular pattern uneven discontinuous coating layer. It will be heat treated for a minute.

  In the device according to the method for forming a coating layer, a discontinuous coating layer of an ink pigment is formed on the top coat of the three coating layer, but is not necessarily limited thereto. After forming the coating layer of the midcoat, a primer coating and a top are formed without forming a discontinuous coating layer of an ink pigment directly on the midcoat by the above-mentioned method without a topcoat. After forming the coating layer only by coating, a discontinuous coating layer of ink pigment may be formed on the top coat by the method as described above.

  In the method for forming the coating layer, the discontinuous coating layer is formed in a state where the midcoat or the topcoat is dry. However, the present invention is not necessarily limited thereto. A discontinuous coating layer may be formed with the top coat wet. When such a method is applied, the size of the discontinuous coating layer, that is, the size of the spot-like protrusions, is smaller than that applied in a dry state. Therefore, the discontinuous coating layer is applied to adjust the size of the discontinuous coating layer. can do.

  Here, in the case of a one-coating layer, the step of sandblasting and the step of applying one of ceramic paint, heat-resistant paint or fluororesin paint and heat-treating at 100 to 150 ° C. for 10 to 15 minutes are optionally omitted. can do. However, when the sandblasting process is performed, the adhesive force of the ceramic paint, heat resistant paint or fluororesin paint applied to the surface of the tool increases.

  In the method for forming the coating layer, the discontinuous coating layer is formed in a state where the one coating layer of the ceramic coating layer, the heat-resistant coating layer, or the fluororesin coating layer is dried, thereby further protruding the surface of the device. However, the present invention is not necessarily limited thereto, and in some cases, the discontinuous coating layer may be formed with the one coating layer of the ceramic coating layer, the heat-resistant coating layer, or the fluororesin coating layer wet. When such a method is applied, the size of the discontinuous coating layer, that is, the size of speckled protrusions, is lower than that applied in a dry state, so the size of the discontinuous coating layer is adjusted. In this case, when it is applied in a mottled state, that is, in a moist state, it is applied in the form of spots, as a result, the degree of protrusion of the spotted projections is lowered.

  By the way, as shown in the drawings, a device whose surface is coated by the method as described above can be typically applied to a kitchen device in which food and drink are mainly in contact with the surface. Can be applied to all instruments that need to be coated.

  Moreover, when the coating layer is formed by the method as described above, in the case of a kitchen appliance, as shown in FIGS. 1 and 2, the surface area touched by the food and drink is further increased compared to other cases, Since heat transfer is performed uniformly and actively, food and drink can be cooked evenly. On the other hand, in the conventional case where the top coat covers the discontinuous coating layer, the discontinuous coating layer is reflected in a state where it is blocked by the top coat, and the gloss effect is insufficient. In this case, the one-coating layer, which is one of the ceramic coating layer, the heat-resistant coating layer, or the fluororesin coating layer, or the discontinuous coating layer is reflected on the top coat, so that the gloss effect can be exhibited more reliably. It can be done.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims.
