Description

Device with thin coating layer having three-dimensionalized pattern by magnetic nanopaticles and method for manufacturing the same}

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 coating layer had to be thick.

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 is to solve the above problems to provide a mechanism having an ultra-thin pattern coating layer three-dimensionally 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 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.

Here, between the surface of the object and the ultra-thin patterned coating layer is preferably a primer coating layer coated as a second resin, and a top coating layer of a transparent third resin material is formed on the upper surface of the ultra-thin patterned coating layer.

In addition, the nanomagnetic particles preferably have a color different from that of the configuration disposed on the bottom surface thereof.

On the other hand, 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 second 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 in accordance with the set pattern by magnetic force, and 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 farther from the polarization line. 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.

At this time, in the second step, in the process of rearranging the nano-magnetic material particles in accordance with the set pattern is preferably made comprising the step of maintaining the rearrangement temperature of the first resin.

Through the above solution of the present invention provides the following effects.

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 according to the viewing angle, and the nanomagnetic particles are distributed to the observer by the rearrangement by magnetic force. A visually distinct three-dimensional appearance can be imparted in the area to provide a new high-quality appearance.

Second, a region in which the nanomagnetic particles are concentrated is rearranged by magnetic force, and thus a more realistic and natural three-dimensional effect may be given since the distribution density change is continuous.

Third, since the intaglio and embossed three-dimensional and high-quality appearance without unnecessary increase in thickness, the appliance to be heated amount such as cooking vessel can be made high-quality products without affecting the heat transfer function at all.

Fourth, the processing time and expense for the formation of the pattern is not increased, and the overall thickness of the coating layer can be maintained within several tens of μm, thereby preventing unnecessary waste of materials.

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.

1 is a cross-sectional view showing a mechanism having an ultra-thin pattern coating layer stereoscopically formed by a nano-magnetic material according to an embodiment of the present invention, Figures 2a and 2b is a nano-magnetic material according to an embodiment of the present invention It is a photograph showing the external appearance of the mechanism provided with the ultra-thin pattern coating layer three-dimensionalized by.

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 exterior panels or cooking vessels of various devices, the object 10 is a non-magnetic metal material forming such an exterior panel or cooking vessel. It can be made of 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. Nano magnetic particles 35 mixed with the first resin by a magnetic force generated by magnetic force generating means such as permanent magnets or electromagnets having polarization lines or the like arranged in a pattern shape set from a lower portion of the object 10. ) 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.

In detail, the nanomagnetic particles are distributed and rearranged at a point corresponding to the polarization line of the magnetic force generating means by magnetic attraction, and thus the distribution density becomes lower since the magnetic attraction becomes weaker as the nano magnetic particles are moved away from the magnetic particles. . Through this, as described below, the continuous difference in the distribution density of the nanomagnetic particles 35 may provide an embossed or engraved effect in appearance, thereby providing a visually three-dimensional 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 surface roughness by sand blasting, and the primer coating layer 20 is firm to the sand blasted surface. After being attached and 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 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 contains a ceramic powder in a fluorine resin, a ceramic, or a heat-resistant paint, and is a dark color such as black, such that the three-dimensionalized ultra-thin pattern coating layer 30 to the color of the nanomagnetic particles 35 mixed therewith. It is preferably formed to have a color different from each other. 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-dimensional ultra-thin pattern coating layer 30 from being peeled off, even if the present invention is applied to a cooking vessel through the nano The hygienic safety performance can be improved by preventing the magnetic 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 intaglio and embossment are clearly observed.

In detail, FIG. 2A is a front view, while FIG. 2B is a sample photograph at an angle viewed from a direction inclined to one side.

As shown in Figures 2a and 2b, the mechanism in which the three-dimensionalized ultra-thin pattern coating layer 30 is formed provides a clear three-dimensional feeling that is indented and embossed. Here, the silver gray portion 36 is a region where the nanomagnetic particles are concentrated by rearrangement, and the portion 37 that looks as deep as it is recessed as a dark or black color of the inner portion partitioned therein is the nanomagnetic material. It is an area where the 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. 2A, FIG. 2B 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.

As such, although the total thickness of the coating layer is limited to within several tens of μm, the nanolayered particles 35 may be rearranged to an observer because the shape of the coating layer may be stereoscopically shaped as the shadow of the light is changed depending on the viewing angle. As a result, the areas distributed in a concentrated manner may be visually provided with a clear three-dimensional appearance, thereby providing a new high quality appearance.

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

On the other hand, Figure 3 is a flow chart illustrating 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, Figure 4 is three-dimensionalized by a nano-magnetic material according to an embodiment of the present invention It is a schematic diagram showing the manufacturing apparatus of the apparatus provided with the ultra-thin pattern coating layer.

As shown in Figures 3 and 4, in order to manufacture a device having an ultra-thin pattern coating layer three-dimensionalized by a nano-magnetic material according to the present invention, first, a primer coating layer as a second resin on the surface of the object 10 of the non-magnetic material ( Forming 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. 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.

In FIG. 2A and FIG. 2B, the area where the silver-gray portion 36 is concentrated by the rearrangement of the nanomagnetic particles is formed at a point corresponding to the polarization line (101 in FIG. 4) of the magnetic force generating means. When 101 is formed in a pattern set like a lattice, an ultra-thin pattern coating layer three-dimensionally formed into a lattice shape as shown in FIGS. 2A and 2B is formed of nanomagnetic particles.

Here, it is preferable to maintain the rearrangement temperature of the first resin in the process of rearranging the nanomagnetic particles 35 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 μm 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.

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.

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.
