The present invention relates to a method for manufacturing an exterior material that is capable of preventing deformation and wrinkling by heat conduction, and more particularly, in an exterior material that is affected by thermal conduction by a hot wire, such as the surface of an electric mat, and deformation due to heat conduction or handling. Or it relates to a method for manufacturing the exterior material capable of preventing deformation and wrinkles by the thermal conductivity capable of preventing wrinkles.

1 shows an example of an electric mat 20 (utility model registration 288643).

The electric mat 20 includes upper and lower exterior members 21 and 21 'for wrapping a predetermined interior material having a plurality of layers therein, an upper joining member 22 disposed below the upper exterior member 21, A heating wire 25 disposed below the upper joining member 22, a lower joining member 22 ′ disposed below the heating wire 25, and a heat insulating material disposed below the lower joining member 22 ′ ( 27) and a plush mat 28 disposed below the heat insulating material 27 to maintain strength.

The electric mat 20 having such a multilayer structure is provided with two upper and lower joining members 22 and 22 'including a nonwoven fabric 23 coated with a synthetic resin 24 up and down, and the upper and lower two sheets. The heating wire 25 is provided between the joining members 22 and 22 '.

As the synthetic resin 24, for example, polypropylene resin may be most preferably applied.

In addition, the upper and lower bonding members 22 and 22 'are formed by coating a synthetic resin 24 having a strong bonding force on the nonwoven fabric 23 having a strong supporting force, thereby heating the heating wire 25 in the mat without a separate bonding means. It becomes possible to fix to the part 26 certainly.

In this case, the exterior material 2 may be made of various materials. Since the mat 10 directly contacts the skin in the process of sitting or lying down, contaminants may penetrate into the exterior material 2 so that the exterior material is generally antifouling, Water repellent is used and it is common to use a variety of decorative patterns formed on the surface for decoration or appearance.

The exterior material 21 can be made of a material having a variety of prices (synthetic fiber, woven fiber), but is usually produced according to the cost.

However, functionally, the packaging material 21 is set on the surface and the lower surface with the heating wire 25 and the upper and lower bonding members 22 and 22 'therebetween, and deformation occurs due to heat conduction by the heating wire 25. There was a problem that there is a possibility that the case may be returned in the initial purchase.

In addition, the exterior material 21 itself usually has a problem in that the surface texture is poor because many cases of using a thin material without a sense of cushion.

In addition, the exterior material has many examples of using a fabric having almost no mechanical strength, so once wrinkles are possible, it is difficult to recover the wrinkles, which is a factor in reducing the repurchase power regardless of the quality of the electric mat.

In addition, when manufacturing an electric mat in a factory, when storing the exterior material in a warehouse, the exterior material becomes hard and shrunk in a cold weather, so when the temperature increases later, the surface strength may increase and the surface strength may drop. In the case there was a problem that the exterior material is broken when handling frozen.

The present invention devised to solve the problems as described above, while maintaining the flatness even when rolling and flattening after rolling and transporting in the form of roll before manufacturing, while being resistant to deformation and wrinkle due to heat conduction electric mat It is a technical problem to solve the provision of a method for manufacturing a packaging material which can prevent deformation and wrinkle prevention by heat conduction, which can be widely used as a surface and lower surface material such as.

The present invention for achieving the technical problem as described above, the surface material comprising a synthetic fiber; An intermediate material that is polyvinyl chloride as a thermosetting material that is bonded to a lower portion of the surface material and has a strength capable of absorbing deformation of the exterior material; Preparing a packaging material comprising a; and a lower surface material which is a nonwoven fabric bonded to the lower portion of the intermediate material; The press-bonding step for the exterior material manufacturing method comprising a; compression bonding step of passing through the compression rollers in the state positioned on the upper, middle, and lower surface materials, respectively, and combined by pressing the surface material, the intermediate material and the lower material; And a cooling step of applying heat to fuse the connection between the surface material, the intermediate material, and the lower surface material, and cooling the compressed material integrally bonded through the compression bonding step to maintain a fixed form at room temperature. The non-woven fabric is controlled by the non-woven lower surface material to control the heat conduction from the skin mat, and the intermediate material has a strength that has a restoring force against deformation and crease by the heat conduction from the lower material.
The exterior material provides a method of manufacturing an exterior material that can prevent deformation and wrinkle prevention by heat conduction to be set on an upper surface of a skin material that is an electric mat.

The scope of the present invention is shown by the following claims rather than the above description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.

The present invention having the configuration as described above will be described in more detail with reference to the following drawings.

The present invention has been described with reference to preferred embodiments of the present invention, but the present invention is not limited to these embodiments, and the claims and detailed description of the present invention together with the embodiments in which the above embodiments are simply combined with existing known technologies. In the present invention, it can be seen that the technology that can be modified and used by those skilled in the art are naturally included in the technical scope of the present invention.

Figure 2 is a schematic diagram showing an example of the packaging material according to the present invention, Figure 3 is a flow chart showing an example of a manufacturing method of the packaging material according to the invention, Figure 4 is a schematic diagram showing a manufacturing process according to FIG. 5 illustrates a state in which the exterior member of the present invention is coupled to the skin member 200 which is an electric mat.

Exterior material 100 that can prevent deformation and wrinkle prevention by the heat conduction according to the present invention is largely formed on the upper and / or lower surface of the skin wear material, the surface material 110; An intermediate material 120 including polyvinyl chloride; And a lower surface material 130 which is a nonwoven fabric.

That is, the sheet-shaped material having three different materials is pressed and manufactured up and down.

First, the skin mounting material 200 is an electric mat with a built-in heating wire as a target to which the exterior material 100 is coupled.

The electric mat includes a heating wire 210 for conducting heat to the exterior material 100 as shown in FIG. 5 so that heat is transferred to the exterior material.

This heat is adjusted to the temperature desired by the temperature controller of the electric mat, but if it is used repeatedly, excessive heat is transferred to the exterior material.

Accordingly, the exterior material 100 is deformed or stretched due to heat conduction, resulting in a problem of inferior durability.

Of course, in order to prevent such excessive thermal conduction, as shown in FIG. 1, two upper and lower joining members 22 and 22 ′ including the nonwoven fabric 23 coated with the synthetic resin 24 may surround the heating wire 25. It is not easy to prevent such excessive thermal conduction in the case of electric mat (medium price product) which does not include such a configuration because the specification varies depending on the product.

In this invention, since the lower surface material 130 of the exterior material 100 is exposed to heat conduction first, the lower surface material 130 is used as a nonwoven fabric.

Such a nonwoven fabric is light in weight and can be ventilated, while allowing the exterior material to have a predetermined thickness, while having a cushioning feeling, and having a low thermal conductivity, thereby preventing a large part of heat transfer.

In other words, the external materials used for electric mats are mostly thin, so they are easy to handle.However, they are difficult to secure a cushioning thickness, which reduces the feeling of use and the risk of breakage. It was common to feel very hot after using an electric mat for more than 1 hour.

Thus, by using the lower surface material 130 of the exterior material as a nonwoven fabric to solve this problem.

The intermediate material 120 of the present invention is coupled to the upper portion of the lower surface material 130.

Since the intermediate member 120 does not allow the exterior member to have a constant thickness, a material having a thin thickness such as a sheet is used.

First, the exterior material 100 is generally rolled and stored in the form of a roll for handling thereof. If there is not enough restoring force, most of the wrinkles will occur when the unfolded exterior material is unfolded.

In particular, when the temperature is low, such as winter, the case 100 is shrunk by the temperature, and because of this shrinkage is not easily restored to its original state even after the crumple 100 is wrinkled, the usability is greatly reduced by the case There was this.

After all, this phenomenon can be solved to ensure the strength by the shrinkage and expansion of the exterior material while having a restoring force for the wrinkle of the exterior material, the bottom material 130 is secured by the non-woven fabric to ensure the resilience to the wrinkle It is not easy to do it, and in particular, there is a limit in securing the strength of the exterior material by shrinkage and expansion, and even if possible, if the exterior material is manufactured by increasing the thickness of the nonwoven fabric, the thickness of the entire exterior material is not only too thick. However, it was not easy to adopt economically.

In the present invention, while ensuring the strength due to the shrinkage and expansion of the packaging material may have a restoring force against wrinkles, and combine the intermediate material 120 that does not thicken the thickness of the packaging material, the intermediate material 120 is a non-woven lower surface material ( 130) to be combined with the non-woven lower surface material 130 to behave integrally.

The intermediate member 120 uses a polyvinyl chloride which is a thermosetting material.

Therefore, the present invention can use the intermediate material produced in the form of a sheet because the thin polyvinyl chloride is used as the intermediate material 120, and since it is a thermosetting material, the bottom material 130 and the heat-sealed can be pressed and bonded to each other. Not only is easy to combine with the 130, but also combined with the lower surface material 130 can increase the mechanical strength of the outer material and while preventing the heat conduction double by the combination of the lower material 130, for the wrinkle of the outer material It can be seen that it is very effective for restoration.

The surface material 110 may use a synthetic fiber, it does not exclude the natural fiber and may be printed on the synthetic fiber to have a variety of patterning effect on the synthetic fiber.

Since the surface material 110 is coupled to the upper portion of the intermediate material 120, since contamination may occur according to the use of the exterior material 100, it is common to carry out water repellent treatment.

In addition, the surface material 110, if the upper surface is treated with an enamel coating (400) to form a smoother surface, if the surface texture is good and can also prevent scratches, it is possible to prevent the dust from sticking easily.

In the present invention, the surface material is to use a fabric made of synthetic fibers, the adhesive is required to bond the surface material to the nonwoven fabric of the lower surface material (130).

However, since the intermediate material 120 is a thermosetting material, the surface material 110 and the lower surface material 130 that are not heat fused through the intermediate material 120 may be coupled to each other by heat fusion.

In addition, the bonding method by the thermal fusion can fully utilize the efficiency of the production because it can use the conventional exterior material manufacturing equipment as it is.

As described above, the exterior material 100 having the structure of the lower surface material 130, the intermediate material 120 and the surface material 110, the lower surface material 130 manufacturing step, the intermediate material 120 manufacturing step as shown in Figs. The intermediate material 120 is fabricated, and the lower surface material 130, the intermediate material 120 and the surface material 110 are compressed by passing between the pressing roller 310 in a state of being positioned at the upper side, the center, and the lower side, respectively. It can be prepared through a compression bonding step of bonding to.

The compression bonding step is only the pressing method of passing through the pressing roller 210 if only enough pressure between the pressing roller 310, the lower surface material 130, the intermediate material 120 and the surface material 110 can be combined. Although it can be simply implemented, the connection portion between the lower surface material 130, the intermediate material 120 and the surface material 110 to be more clearly coupled to the lower surface material 130, the intermediate material 120 and the surface material 110 is heat It is made by the method of thermal fusion while adding.

When the compression bonding step is made by a heat fusion method, the compression treatment unit integrally coupled through the compression bonding step while fixing the connection between the heat-sealed lower surface material 130, the intermediate material 120 and the surface material 110 It is preferably configured to further include a cooling step of cooling to maintain a fixed form at room temperature.

In forming the enamel coating part 400 on the upper surface of the surface material 110, the compression treatment is integrally passed through the compression bonding step between the coating roller 320 coated with the liquid enamel on the surface. Or, it can be simply processed through the enamel coating step of spraying and drying the liquid enamel on the surface of the compression treatment.

In addition, the pressing roller and the coating roller of the enamel coating step and the spray nozzle of the compression bonding step, as shown in Figure 4 so that the pressing and coating treatment can be carried out while continuously transporting the pressing treatment in the specified direction It is preferable to be provided at a distance apart on the transport path of the treatment.

5 is a view showing a state in which the exterior member 100 according to the present invention is formed on the outside of the electric mat, the surface member constituting the exterior member 100 is a case of using a synthetic fiber treated with wood printing by the wood pattern. It can be seen that.

The exterior material 100 can prevent a considerable portion of the heat conduction can sufficiently prevent the deformation of the exterior material due to the heat conduction, combined with the non-woven lower surface material 130 can not only ensure sufficient restoring force for wrinkles, It can have a feeling of cushion through a predetermined thickness can be utilized in various types of electric mats and the like.
