The present invention relates to a device having a three-dimensionalized ultra-thin pattern coating layer, and more particularly, to a device provided with a three-dimensional ultra-thin pattern coating layer made of a nanomagnetic material.

In general, a flat pattern is formed on the surface of an appliance such as an exterior panel or a cooking vessel of a product through a screen method, a pad method, a spray injection method, or the like.

On the other hand, attempts to form a three-dimensional pattern in the advanced product differentiated from the prior art, and to form such a three-dimensional pattern using a mold whose surface thickness is adjusted to correspond to the pattern or cutting or pressing press method This has been used.

Therefore, the pattern formed in this way has a relatively large difference in thickness, and even if a coating layer is formed on the upper surface, the curvature has to be formed corresponding to the three-dimensional pattern on the surface, and the flat and smooth surface has a three-dimensional pattern. In order to form, the thickness of the coating layer had to be thickened.

However, in this case, the volume of the product is increased due to unnecessary thickness increase, and the formed pattern is only a rough form of general intaglio and embossing, and there is a problem in that it cannot present an advanced aesthetic of the product. In addition, due to the increase in the thickness generated in the process of forming a three-dimensional pattern in the device to be heated amount such as cooking vessels there was a problem that the heat transfer rate is lowered to impair the function of the product.

In addition, the processing time for the formation of the pattern to increase the cost, there was a problem such as excessively takes the coating layer material.

The present invention has been made to solve the above problems to provide a mechanism having a clear ultra-thin pattern coating layer while being three-dimensionally formed by a nano-magnetic material in a thin and compact structure.

In order to solve the above problems, the present invention has a pattern region formed as a thickness through which the magnetic force is transmitted, the object made of a nonmagnetic material; And a three-dimensional ultra-thin pattern coating layer formed on the upper surface of the object by coating the first resin in which the nano magnetic particles are mixed and formed as the nano magnetic particles are rearranged in a pattern set by the magnetic force of the magnetic generating means. The magnetic force generating means is provided to have a polarization line, and the nanomagnetic particles have a high rearranged distribution density at a point corresponding to the polarization line, and the distribution density decreases as the distance from the polarization line decreases. Provided is a mechanism provided with an ultra-thin pattern coating layer three-dimensionalized by a nano-magnetic material characterized in that the pattern coating layer is formed.

In addition, the present invention comprises a first step of forming and drying a primer coating layer as a second resin on the surface of the object of the non-magnetic material; Applying a first resin mixed with nano-magnetic material particles having a different color from the first resin on the upper surface of the primer coating layer, by placing a magnetic force generating means having a polarization line to provide a magnetic force of the pattern set in the lower portion of the object The nanomagnetic particles are rearranged according to the set pattern by magnetic force, but the rearranged distribution density is high at the point where the nanomagnetic particles correspond to the polarization line, and the distribution density is lowered as the distance from the polarization line decreases. A second step of forming the ultra-thin pattern coating layer; And a third step of drying the ultra-thin patterned coating layer. The method provides a method of manufacturing a device having an ultra-thin patterned coating layer stereoscopically formed by a nanomagnetic material.

The present invention provides the following effects through the above solution.

First, although the total thickness of the coating layer is limited to within several tens of micrometers, it shows a three-dimensional shape as the shade of the light is changed depending on the viewing angle, the nanomagnetic particles to the observer in the polarization region where a plurality of magnets abut As rearranged by the amplified magnetic force, a visually distinct and vivid three-dimensional appearance is provided in a concentrated area, thereby providing a new high-quality appearance.

Second, since the nanomagnetic particles are rearranged by magnetic force, since the distribution density change thereof is continuous, a more realistic and natural three-dimensional feeling can be given.

Best Modes for Carrying Out the Invention The best embodiments of the invention will be described in more detail below with reference to the accompanying drawings.

Hereinafter, with reference to the accompanying drawings will be described in detail a mechanism and a method of manufacturing the ultra-thin pattern coating layer provided by the nano-magnetic material according to a preferred embodiment of the present invention.

As shown in FIG. 1, the apparatus having the ultra-thin pattern coating layer stereoscopically formed by the nanomagnetic material according to the present invention includes the object 10 and the stereoscopic ultra-thin pattern coating layer 30. Here, the apparatus provided with the ultra-thin pattern coating layer three-dimensionally by the nano-magnetic material may be made of a cooking vessel, such as a frying pan, or exterior panels of various devices, and the object 10 is a non-magnetic panel forming such an exterior panel or a cooking vessel. It may be made of an adult metal plate.

In detail, the object 10 has a pattern region formed as a thickness through which magnetic force is transmitted, and is preferably made of a nonmagnetic material such as aluminum.

On the other hand, the upper surface of the object 10 is provided with an ultra-thin pattern coating layer 30 is three-dimensional to a very thin thickness. Here, the three-dimensionalized ultra-thin pattern coating layer 30 is formed by coating the first resin mixed with the nano-magnetic material particles 35, is formed as the nano-magnetic material particles are rearranged in a pattern set by the magnetic force in the viewing direction Therefore, a three-dimensional effect is provided.

At this time, the first resin is made of a synthetic resin material, when the object is a cooking vessel is preferably made of a transparent material made of a fluorine resin, ceramic, or heat-resistant paint harmless to the human body. In addition, the nanomagnetic particles 35 are heated to a low cost and non-toxic metal, surfactant complex, etc. slowly and then further heated for more than a predetermined time at 300 degrees Celsius or more, 12nm (nanometer, 1 nanometer) in a few hours It is preferable that it consists of uniform magnetic iron oxide nanoparticles produced as a particle size of 1 billion = 1 billion. Techniques for producing such nanomagnetic particles are disclosed in detail in US Pat. Nos. 4,206,094, 4,219,411, 4,4454,234, 4,863,715 and Korean Patent No. 967708.

Thus, the first resin is preheated and melted to have a value equal to or lower than a set viscosity, and the surface of the object is mixed so that the nanomagnetic particles having an average particle diameter of several tens of nanometers (nm) are uniformly distributed. Is applied to. Thereafter, the nano-magnetic material particles 35 mixed in the first resin by magnetic force generated by magnetic force generating means, such as permanent magnets or electromagnets, in which polarization lines or the like are arranged in a pattern shape set from the lower part of the object 10. It is moved in the direction of forming the set pattern.

At this time, the nano-magnetic material particles 35 are moved to form a pattern set together with the first resin to form a three-dimensional pattern. In addition, in order to clearly display such a three-dimensional pattern, the first resin and the nanomagnetic particles 35 mixed with the first resin may have different colors from those of the surface of the object disposed on the bottom surface of the object or a primer coating layer described below. It is desirable to have.

Figure 2 is a flow chart showing a method of manufacturing a device having an ultra-thin pattern coating layer three-dimensionalized by a nano-magnetic material according to an embodiment of the present invention, Figures 3a and 3b is a nano-magnetic material according to an embodiment of the present invention It is a schematic diagram which shows the manufacturing apparatus of the apparatus provided with the three-dimensional ultra-thin pattern coating layer.

Specifically, referring to FIGS. 3A and 3B, the magnetic force generating means 100 provides a magnetic force of a pattern set by the polarization line 101 formed at a point where the plurality of magnets 100a abut. At this time, the magnetic force is amplified in the polarization line 101 formed at the point where the plurality of magnets abut.

The polarization line 101 is formed at the point where the N pole and the S pole of the independent magnets 100a come in contact with each other. . As described above, in the polarization line 101 formed at the point where the plurality of individual magnets 100a abut, the magnetic forces of the two magnets are combined and amplified, and in the polarization line 101, the magnetic force is significantly stronger than the magnetic force of a single magnet. To provide.

In addition, the nano-magnetic particles contained in the pattern coating layer 30 is pulled by the magnetic attraction at the point corresponding to the polarization line 101 is moved by the magnetic attraction, the distribution density after rearrangement is high, the magnetic attraction is further away from it The weaker the density, the lower the distribution density. In particular, in such a polarization line 101, the magnetic force is amplified to draw the nano-magnetic material particles by a strong magnetic force can form a three-dimensional pattern of clearer shape. Through this, as described below, the continuous difference in the distribution density of the nanomagnetic particles 35 may provide a visually stereoscopic appearance that can be commercialized by providing an embossed to engraved effect in appearance.

Here, the configuration disposed on the lower surface of the first resin may be the surface of the object, but a primer coated as a second resin made of a fluorine resin or the like between the surface of the object 10 and the ultra-thin pattern coating layer 30. It is preferable that the coating layer 20 is further provided. Typically, in order to increase the adhesion between the resin material and the object surface of the metal material, the object surface of the metal material increases the surface roughness by sandblasting. The primer coating layer 20 may be firmly attached to the sand blasted surface and, after being dried, its upper surface may function as a base layer to which the ultra-thin pattern coating layer 30 is firmly attached.

Moreover, the movement for rearrangement of the nanomagnetic particles and the first resin by magnetic force in the state where the first resin is preheated and molten can be made smoothly along the smooth and flat upper surface of the primer coating layer 20 disposed on the lower surface thereof. have.

In addition, the primer coating layer 20 is made of a fluorine resin, ceramic, or a heat resistant paint, such as ceramic powder is contained in a dark color such as black. In addition, the three-dimensionalized ultra-thin pattern coating layer 30 to the color of the nano-magnetic material particles 35 mixed thereto is preferably formed to have a different color from the color of the primer coating layer. At this time, the three-dimensionalized ultra-thin pattern coating layer 30 is formed in a color contrasted with the color of the primer coating layer, preferably the nano-magnetic material particles 35 are treated to be formed in a light metal color to increase the stereoscopic effect. Do.

In addition, the top coating layer 40 of a transparent third resin material is preferably formed on the top surface of the three-dimensionalized ultra-thin pattern coating layer 30. The top coating layer 40 functions as a layer for protecting the nanomagnetic particles 35 of the iron oxide component contained in the three-dimensionalized ultra-thin pattern coating layer 30 from being peeled off. Through this, even if the present invention is applied to a cooking vessel or the like, it is possible to improve the hygiene safety performance by preventing the nanomagnetic particles from peeling off the surface.

Through such a configuration, although the total thickness of the primer coating layer 20, the three-dimensionalized ultra-thin pattern coating layer 30, and the top coating layer 40 is limited to within several tens of micrometers, the three-dimensionalized ultra-thin pattern coating layer 30 may provide an appearance given a three-dimensional appearance in which three-dimensional intaglio and embossment are clearly observed.

As such, although the overall thickness of the coating layer is formed to be limited to within several tens of micrometers, it shows a three-dimensional shape as if the shade of light to be transmitted is changed according to the viewing angle. Therefore, a visually distinct three-dimensional appearance may be given to the observer in a region where the nanomagnetic particles 35 are concentrated by rearrangement, thereby providing a new high-quality appearance.

In other words, since the region where the nanomagnetic particles 35 are concentrated is rearranged by magnetic force and the distribution density change is continuous, the angle of reflectance of light projected onto the nanomagnetic particles 35 is continuously changed. As a result, a more realistic and natural three-dimensional feeling such as intaglio or embossing can be provided.

On the other hand, the method of manufacturing a device provided with an ultra-thin pattern coating layer three-dimensionalized by a nano-magnetic material according to an embodiment of the present invention.

As shown in Figure 2 to 3b, in order to manufacture a device equipped with an ultra-thin pattern coating layer three-dimensionally by a nano-magnetic material according to the present invention, first, a primer coating layer as a second resin on the surface of the non-magnetic material (10) Form 20) of Figure 1 is preferably dried (S100).

Here, the primer coating layer is firmly attached to the surface of the sand blasted object, and after being dried, the upper surface thereof may function as a base layer to which the ultra-thin pattern coating layer 30 is firmly attached. Moreover, the movement for rearrangement of the nanomagnetic particles and the first resin by magnetic force in the state where the first resin is preheated and molten can be smoothly made along the smooth and flat upper surface of the primer coating layer disposed on the lower surface thereof.

Next, the first resin is mixed with the nano-magnetic material particles having a different color from the first resin on the upper surface of the primer coating layer (S200). And, by placing a magnetic force generating means such as permanent magnets or electromagnets to provide a magnetic force of the pattern set in the lower portion of the object, the nano-magnetic material particles 35 are rearranged in accordance with the set pattern by the magnetic force is a three-dimensional ultra-thin pattern coating layer 30 is formed (S300).

At this point, the nanomagnetic particles 35 have a rearranged distribution density at a point corresponding to the polarization line 101 of the magnetic force generating means 100, and the farther therefrom, the lower the distribution density. Through this, a continuous difference in the distribution density of the nanomagnetic particles 35 may provide an embossed to engraved effect in appearance, thereby providing a visually three-dimensional appearance. In this way, a clear three-dimensional pattern can be formed by the magnetic force amplified by the polarization lines formed at the points where the N poles and the S poles of the plurality of magnets abut each other.

Furthermore, since the region where the nanomagnetic particles 35 are concentrated is rearranged by magnetic force, and the distribution density thereof is continuous, the reflectivity of the light projected onto the nanomagnetic particles 35 is continuously changed at an angle of view. Thus, a more realistic and natural change in three-dimensional appearance can be observed visually.

Here, it is preferable to maintain the rearrangement temperature of the first resin when the nanomagnetic particles 35 are rearranged according to the set pattern. Here, the rearrangement temperature means a temperature state in which the nanomagnetic particles 35 are moved and rearranged by the magnetic force as the first resin is molten. To this end, the order of heating to preheating may be appropriately changed to melt the first resin and lower the viscosity so that the nanomagnetic particles are easily rearranged.

Thereafter, the ultra-thin patterned coating layer 30 is dried (S400), and the top coating layer (40 in FIG. 1) is preferably formed on the upper surface of the dried ultra-thin patterned coating layer 30. Here, the primer coating layer, three-dimensionalized ultra-thin pattern coating layer, the top coating layer is made of a synthetic resin material, such as fluorine resin, ceramics, or heat-resistant paint, the overall thickness is limited to within several tens of ㎛ to prevent unnecessary material cost increase. Of course, the resin forming the three-dimensionalized ultra-thin patterned coating layer and the top coating layer is preferably made of a transparent material so that the three-dimensionalized pattern is displayed on the outside.

Figure 4 is a cross-sectional view showing a mechanism having a multi-layered ultra-thin pattern coating layer three-dimensionalized by a nano-magnetic material according to an embodiment of the present invention.

As shown in FIG. 4, after the primer coating layer is formed on the surface of the sandblasted device 10, the first glyph coating layer 30a and the second glyph coating layer 30b are formed on the upper side of the primer coating layer. Are formed sequentially. In addition, the top coating layer 60 is preferably formed on the upper surface of the second glyph coating layer 30b.

Here, the first glyph coating layer 30a and the second glyph coating layer 30b are applied in multiple layers, and the glyph coating layers each include the first nanomagnetic particles 35a and the second nanomagnetic particles 35b. . In addition, after the first nano-magnetic particles contained in the first pattern coating layer to form a three-dimensional pattern corresponding to the polarization line of the magnetic force generating means 100, the second nano-magnetic particles contained in the second pattern coating layer The three-dimensional pattern can be formed in multiple layers corresponding to the polarization lines of other magnetic force generating means.

Furthermore, the first nanoparticle particles 35a and the second nanomagnetic particles 35b that are patterned on the first glyph coating layer 30a and the second glyph coating layer 30b to form a three-dimensional pattern, respectively, It can be formed differently to form an innovative and refined multi-dimensional three-dimensional ultra-thin pattern coating layer. In addition, the nanomagnetic particles may be formed to have a color distinct from the color of each coating layer.

Here, the magnetic force generating means 100 is to be provided in combination of a plurality of independent magnets (100a) to have a polarization line 101 of a set pattern. As a result, the

nanomagnetic particles

35a and 35b have a high rearranged distribution density at a point corresponding to the polarization line and a low distribution density at a portion away from the polarization line, so that the three-dimensional appearance is clear and the difference in distribution density is clear. The pattern coating layer may be formed.

On the other hand, Figure 5 is a schematic diagram showing an apparatus for manufacturing a device having an ultra-thin pattern coating layer three-dimensionalized by a nano-magnetic material according to another embodiment of the present invention.

As shown in Figure 5, the magnetic force generating means is a planar magnet 110 that provides a magnetic force, and is disposed on the upper surface of the magnet 110 to transfer the magnetic force, but the pattern plate 120 having a groove or a hole of a predetermined pattern is formed It may be made, including.

That is, since it is not easy to form a pattern on the magnet itself, the magnetic force is transmitted in a shape corresponding thereto by the pattern plate 120 of the magnetic metal material having the pattern set on the upper surface of the magnet. Through this, the nano-magnetic material particles 35 contained in the first resin applied to the object 10 are rearranged so as to be concentrated in a pattern corresponding to the magnetic attraction according to the set pattern, the three-dimensional ultra-thin pattern coating layer 30 ) Can be achieved.

On the other hand, Figure 6a and Figure 6b is a photograph showing the appearance of the apparatus provided with a ultra-thin pattern coating layer three-dimensionalized by a nano-magnetic material according to an embodiment of the present invention. Here, FIG. 6A is an angle viewed from the front while FIG. 6B is a sample photograph at an angle viewed from a direction inclined to one side.

As shown in FIGS. 6A and 6B, the mechanism in which the three-dimensionalized ultra-thin pattern coating layer 30 is formed provides a clear three-dimensional feeling in which the intaglio and the embossment are distinguished. Here, the silver gray portion 36 is a region where the nanomagnetic particles are distributed by the rearrangement, and the portion 37 that looks so deep as if it is recessed as the inner dark or black color partitioned therein is the above. It is an area where nanomagnetic particles are sparsely arranged so that their lower structure (primer coating layer to object surface) is projected.

That is, the area in which the nanomagnetic particles 35 are concentrated by rearrangement is visually sensed as protruding by embossing. Compared to FIG. 6A, FIG. 6B shows an area in which the nanomagnetic particles are concentrated by rearrangement. The shadows of the shadows are changed in three dimensions and visually sensed as protruding by a few cm.

6A and 6B, a region in which the silver-gray portion 36 is concentrated in the nanomagnetic particles by rearrangement is formed at a point corresponding to the polarization line of the magnetic force generating means, and the polarization line 101 is lattice-shaped. When formed in a pattern set as described above, the ultra-thin pattern coating layer three-dimensionally formed into a lattice shape as shown in FIGS. 6A and 6B is formed of nanomagnetic particles.

As described above, the present invention is not limited to the above-described embodiments, but may be modified and implemented by those skilled in the art without departing from the scope of the claims of the present invention. Such modifications are within the scope of the present invention.
