Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

The embodiments of the present invention will be described by those skilled in the art to which the present invention is applicable.

Therefore, since the embodiments of the present invention can be modified in various other forms, the claims of the present invention are not limited to the embodiments described below.

1 is a process chart showing the overall working process of the cooking vessel manufacturing method according to an embodiment of the present invention.

2 is a view schematically illustrating a cooking container V manufactured through the processes of FIG. 1, wherein the container body 2 includes a cooking space V1 having a predetermined size, and the container body ( 2) It may be made of a conventional frying pan (fryingpan) attached to the handle 4 on one side.

Among the processes of FIG. 1, reference numeral S1 denotes a process of molding the container body.

The process of forming the container body (S1), as shown in Figure 3 can be carried out in a conventional diecasting method using two molds, that is, the upper mold (M1) and the lower mold (M2). have.

That is, the upper and lower molds M1 and M2 are arranged up and down as shown in FIG. 3 and provide a predetermined molding space Q corresponding to the container body 2.

In addition, the molding space Q is set to receive the molding raw material W in a conventional manner from the raw material injector M3 connected to one side of the lower mold M2 in a tubular body (see FIG. 3).

Therefore, in the state in which the upper mold M1 and the lower molds M1 and M2 are merged with each other, a molding raw material W is injected into the molding space Q to thereby form the container body 2 as shown in FIG. 2. It can be molded easily by the die casting method.

In the above description, molding of the container body 2 by the aluminum die casting method is shown in the description and drawings as an example, but the present invention is not limited thereto.

For example, although not shown in the drawing, it may be formed by a gravity casting method (or an aluminum sheet drawing or spinning method) widely used for forming a cooking container.

Next, a process (S2) of forming a first coating layer among the processes of FIG. 1 is performed.

The process of forming the first coating layer (S2), the first coating layer that serves as a kind of base layer to give a unique color to the outer surface of the container body (2) and easy transfer printing ( It is for forming C1).

That is, the coating operation uses the first coating liquid L1 and sprays the first coating liquid L1 toward the outer circumferential surface of the container body 2 using the spray gun G as shown in FIG. 4. You can proceed in such a way.

The first coating liquid L1 may be, for example, a coating liquid having a trade name "EG-07" sold by "Gyeonggi Chemical Co., Ltd.". In particular, since the coating liquid is known to have excellent surface adhesion and strength, the coating liquid may be used as the first coating liquid L1.

In addition, the "EG-07" coating solution may be, for example, by selecting a coating solution having a variety of inherent colors that meet the required specifications, for example, a black color that is frequently used as a finish color of the outer surface of the container body 2, You can use

Therefore, the first coating liquid L1 may be coated on the outer circumferential surface of the container body 2 as shown in FIG. 5 by the above coating operation, thereby forming the first coating layer C1 to a predetermined thickness.

The thickness of the first coating layer C1 may be formed within a range of about 9 microns to 12 microns.

If the first coating layer (C1) is thinner than the above thickness range, it is difficult to form the coating layer to fill the minute uneven portion of the outer surface of the container body 2 can not perform the role of the base surface smoothly .

In addition, if it is thicker than the above-described thickness range, the amount of coating liquid used increases, so that not only the manufacturing cost increases but also a factor of lowering the adhesive strength with the container body 2.

In addition, when the inner surface of the cooking space V1 of the container body 2 forms a conventional functional coating layer V2 (eg, a marble coating layer, a ceramic coating layer) having a function of preventing food from sticking during cooking, for example. good.

Since the operation of forming the functional coating layer (V2) can be easily carried out by those skilled in the art, more detailed description thereof will be omitted.

The cooking vessel manufacturing method according to an embodiment of the present invention may further comprise a step (S3) of firing the first coating layer.

The step S3 of firing the first coating layer is for firing the first coating layer C1 coated on the outer circumferential surface of the container body 2 in a semi-cured state.

Although the baking operation is not shown in figure, it can advance by the method which makes the said container main body 2 pass inside a normal electric or gas baking furnace.

At this time, the firing temperature is preferably baked for 15 to 20 minutes at a relatively low temperature (about 230 degrees Celsius) so that the first coating layer (C1) is a semi-cured state.

In particular, when the first coating layer (C1) is fired in a semi-cured state as described above, the decorative transfer paper layer (D) is attached to the first coating layer (C1) by attaching a decorative transfer paper (P) to the first coating layer (C1) by a transfer printing method. When forming, the adhesion can be increased.

In addition, when the second coating layer (C2) is formed on the first coating layer (C1) in the process described later can improve the adhesion between the coating layer.

When the baking operation of the first coating layer C1 is performed as described above, for example, the coating liquid L1 of the first coating layer C1 may be prevented from flowing down, and the next process may be rapidly performed.

Next, a process (S4) of forming a decorative transfer paper layer is performed among the processes of FIG.

The step (S4) of forming the decorative transfer paper layer is for forming a decorative pattern on the outer surface of the container body 2 by a decalcomania method.

That is, the process of forming the decorative transfer paper layer (S4), by attaching the decorative transfer paper (P) as shown in Figure 6 on the first coating layer (C1) baked in a semi-cured state on the outer surface of the container body (2) Proceed.

The decorative transfer paper P has a structure capable of providing a decorative pattern having wear resistance and heat resistance.

For example, the decorative transfer paper P may include a paper sheet P1 having a water-soluble starch film P2 on one surface, a base film P3 formed on the water-soluble starch film P2, and the like. And a color film P4 and a protective film P5 formed on the base film P3, and a separation film P6 and a vinyl film.

The paper base (P1) and the water-soluble starch film (P2) is provided in the same structure as that applied to a conventional ceramic transfer paper, the base film (P3) is mainly used as a fireproof material (zircon, zircon, White powder) is composed of a mixture of a certain amount of acrylic resin (acrylic resin) is mixed to play a role (white surface) to highlight the intrinsic color of the color film (P4).

In addition, the color film P4 and the protective film P5 of the decorative transfer paper P are manufactured to have characteristics that match the aluminum material of the container body 2.

That is, the color film P4 is composed of a mixture of a certain amount of medium mixed in a pigment, and is formed on the base film P3 by normal silkscreen printing to have a predetermined pattern.

The pigment is intended to impart an inherent color, and may be used in an inorganic pigment. This inorganic pigment is preferable as the pigment of the color film P4 because it is excellent in heat resistance as compared with the organic pigment.

In addition, the media plays a role of stably holding the pigment (binder), and an acrylic resin may be used among transparent resins. In particular, acrylic resins are known to be relatively excellent in heat resistance (about 400 degrees Celsius or more) and wear resistance compared with other synthetic resins.

What is necessary is just to mix the said pigment and median in 6 (pigment): 4 (media) ratio, for example.

If the mixing ratio of the pigment is higher than the above ratio, the adhesion and the wearability may be lowered.

On the other hand, if the media is higher than the above ratio, the inherent color may be blurred, and if it is lower than the above ratio, satisfactory stability cannot be expected.

The protective film P5 is for protecting the color film P4 and may be formed by applying a transparent resin solution.

For example, a transparent acrylic resin having excellent heat resistance and abrasion resistance among resins may be coated on the color film P4 to form the protective film P5 in a state covering the entire outer surface of the color film P4.

That is, when the protective film P5 is formed while covering the color film P4 as described above, heat resistance and wear resistance (impact resistance) can be further provided to the outer surface of the color film P4.

Therefore, when the acrylic resin is mixed with the medium in the pigment of the color film P4 and the protective film P5 is formed of the acrylic resin as described above, the container body 2 is prepared at a general cooking temperature (about 260 degrees Celsius). Even when heated to the color film P4 can maintain a stable state.

Therefore, according to the structure of the decorative transfer paper P, the container body (P4) in the state that can prevent the phenomenon that the color film P4 is discolored by high heat or damaged (wear) by contact or impact, etc. as much as possible 2) Decorative pattern can be given to the outer surface.

In addition, the decorative transfer paper P may be attached to the first coating layer C1 of the container body 2 by a transfer printing method such as ceramics or glass.

In other words, if the water-soluble starch film (P2) is melted, the base film (P3) is separated from the paper sheet (P1) by immersing in water for a predetermined time before attaching the decorative transfer paper (P) to the container body (2) side.

When the base film P3 separated from the paper sheet P1 is pasted on the first coating layer C1 of the container body 2, the color film P4, the protective film P5, and the separator P6 are attached to the container body. (2) It is stuck to the outer surface.

Then, after the color film P4 is sufficiently dried, the separation film P6 and the vinyl film may be separated and removed from the protective film P5 of the color film P4.

Such a transfer printing job can be easily carried out by those skilled in the art, so a detailed description thereof will be omitted.

Therefore, in the step (S4) of forming the decorative transfer paper layer, the decorative transfer paper (P) is transferred to the first coating layer (C1) of the outer surface of the container body (2) by the transfer printing as shown in FIG. The decorative transfer paper layer D may be formed on the coating layer C1.

When transfer printing the decorative transfer paper (P) as described above, for example, if the transfer printing operation is carried out without the first coating layer (C1) formed on the outer surface of the container body (2) the container body (2) The phenomenon that the decorative transfer paper P is easily dropped may occur due to minute uneven parts of the outer surface.

Then, in the state in which the decorative transfer paper P is attached to the container main body 2 as described above, it is good to proceed with the operation of removing water between these attachment surfaces.

For example, as shown in FIG. 8, the upper surface of the decorative transfer paper P attached to the container body 2 may be removed by pushing or wiping the upper surface of the decorative transfer paper P with a squeegee 6. Thus, by removing the water between the attachment surface, it is possible to prevent the black red, blister layer or the like on the transfer printing surface.

In addition, what is necessary is just to carry out the operation | movement which dries the transfer paper decorative transfer paper layer D printed as mentioned above at predetermined temperature.

That is, although not shown in the drawings, for example, the decorative transfer paper layer D may be dried in a manner of naturally drying within 4 hours to 12 hours at a drying temperature of approximately 25 degrees to 28 degrees Celsius. As such, when the decorative transfer paper layer D is dried, adhesion and surface strength are further improved.

The cooking vessel manufacturing method according to an embodiment of the present invention may further include a step (S5) of forming a second coating layer as shown in FIG.

The step (S5) of forming the second coating layer, to form a transparent or translucent protective film on the outer surface of the container body 2 to protect the decorative transfer paper layer (D) and the first coating layer (C1). It is for.

That is, the second coating liquid L2 is used for the coating operation, and the second coating liquid L2 is sprayed toward the outer circumferential surface of the container body 2 using the spray gun G as shown in FIG. 9. You can proceed.

For example, the second coating liquid L2 may be a transparent or translucent clear color coating liquid in a coating liquid of "EG-07" sold by "Gyeonggi Chemical Co., Ltd.".

Therefore, the second coating layer C2 may be formed by covering the first coating layer C1 and the decorative transfer paper layer D on the outer surface of the container body 2 by the coating operation as described above. 10)

In particular, since the second coating layer (C2) is made of a transparent or semi-transparent coating layer, the protective film in a state in which the intrinsic color and the decorative pattern of the first coating layer (C1) and the decorative transfer paper layer (D) are visible to the outside. To provide.

Therefore, the second coating layer (C2) can protect the first coating layer (C1) and the decorative transfer paper layer (D) from various impacts, friction, and high heat, so that the intrinsic aesthetics of the outer surface of the container body (2) ( Collar and vignette) can be maintained for a long time.

In addition, the thickness of the second coating layer C2 may be formed within a range of about 8 microns to 12 microns.

If it is thinner than the above thickness range, it is difficult to obtain satisfactory heat resistance, abrasion resistance, impact resistance, etc., and if it is thicker than the above thickness range, the amount of the coating liquid is increased, so that the manufacturing cost increases and the coating layer is easily peeled off. Can lose.

The cooking vessel manufacturing method according to an embodiment of the present invention may further include a step (S6) of firing the second coating layer.

The step S6 of firing the second coating layer is for uniformly curing the second coating layer C2 coated on the outer circumferential surface of the container body 2.

Although not shown in the figure, this firing operation can be carried out by passing the container main body 2 into a normal electric or gas firing furnace in the same manner as the firing operation of the first coating layer C1 described above.

At this time, the firing temperature is preferably baked for about 15 to 20 minutes within about 260 degrees to 280 degrees Celsius so that the second coating layer (C2) is completely cured.

As such, when the second coating layer C2 is calcined, the surface strength of the coating surface is improved, and thus, satisfactory heat resistance, abrasion resistance, impact resistance, and the like are obtained.

Therefore, the first coating layer (C1) and the decorative transfer paper layer (D) by the second coating layer (C2) can be more securely protected from various impacts, friction, high heat.

When the second coating layer C2 is calcined as described above, work time and productivity may be improved by significantly reducing the time required to cure the second coating layer C2.

Therefore, as shown in FIG. 11, the decorative transfer paper layer D having improved wear resistance and heat resistance on the outer circumferential surface of the container body 2 is integrally attached by transfer printing. ) Can be produced easily.

In particular, the decorative transfer paper layer (D) is not only the color film (P4) of the decorative transfer paper (P) is covered with a protective film (P5), one side (inner side) and the other side (outer side) is the first coating layer ( It is provided on the outer surface of the container body 2 in a state of being wrapped with C1) and the second coating layer (C2), so as to ensure more improved resistance from various impacts, frictions, and high temperatures, so that the outer surface aesthetics of the cooking vessel (V) can be kept for a long time.
