Description

TECHNICAL FIELD [0001] The present invention relates to a composite foil for a trim,

The present invention relates to a composite foil for trim and a method of manufacturing the same, and more particularly, to a composite foil for trim used for decorating and decorating products in all fields including automobile interior materials and communication appliance parts, .

Generally, in the automobile interior materials and communication appliance parts industry, there have been attempts to transfer wood texture such as natural wood, glued laminated wood, and veneer wood to the trim surface in order to provide a deep and classic quality.

For example, for use as an interior trim of some luxury vehicles, trim parts made from natural wood or glued wood have been milled and laminated and glued to natural wood or laminated wood.

However, the trim parts manufactured in this manner have a difficulty in expanding the market due to the high production cost, compared to bringing in a sense of quality, and the bent portions of the milled trim of the built-in trim are easily broken, Respectively.

On the other hand, the technique of bonding natural wood or veneer wood veneer to the surface of furniture can be used only for a product having a flat surface and can not be applied to a product having a complicated three-dimensional shape as in the interior of automobiles or communication appliances.

As a background of the invention, there is a trim component for a built-in trim for a vehicle and a method of manufacturing the same, as in Patent Document 1, wherein the trim component is composed of a supporting material such as a fabric and a decorative material attached thereon, In order to be used as a trim component, the safety pad and the supporting material are separately manufactured, or the expanded polypropylene molded article is integrally manufactured, and the texture of the natural wood and the laminated wood can not be transferred as it is to the trim surface.

In addition, in Patent Document 1, the trim member for a built-in vehicle of a vehicle is not a fabric product rolled up in a roll form, but merely a decorative material having a three-dimensional shape corresponding to a molding frame is incorporated into a laminate. There is a disadvantage that a decorative material must be produced separately.

Another technique of the background of the invention is a method of manufacturing a vehicle trim component by compression and injection molding as in Patent Document 2. [ Patent Document 2 proposes a vehicle trim component by disposing a fiber panel on a first surface of a mold cavity, pressing the fiber panel, and injecting resin into the mold cavity. Here, conventional fiber panels include a combination of structural fibers and thermoplastic resins. The structural fibers are synthetic fibers such as natural fibers such as hemp, wood, flax, hemp, and sand, and / or synthetic fibers such as glass fiber, carbon fiber and polymer fiber. Since natural wood and laminated wood are not used as they are, It is difficult to realize a superior sense of quality such as the texture, the pattern and the curved shape of the wood.

Natural wood or gypsum wood is processed and manufactured in the form of a thin sheet. However, when a natural wood or gypsum wood sheet is pressed and molded to give a 3D solid shape due to the nature of the natural wood or gypsum wood, most of the sharp edges It has the disadvantage that the wood sheet structure breaks or breaks at the deeply punched portions.

Further, when the natural wood or laminated wood sheet is subjected to the thermal processing process, a phenomenon that the natural wood or the laminated wood sheet is intended to be restored to its original shape is generated, and thus the corner radius value of the trim part shape can not be realized.

Therefore, in order to maximize the high quality of trim parts in automobile interior materials and telecommunication appliance parts industry, it has a three-dimensional shape as a trim part while having the same texture as real wood, and a wood structure is broken or broken There is a demand for a new technology for a trim member that can modify the inherent physical properties of wood and can be wound and stored as a fabric form.

The second nonwoven fabric 25 used in the extrusion tee joint device 310 shown in Fig. 1 has a thickness of 3 to 5 mm and may have the same width as the foil base material S5, It may be a polyester nonwoven fabric having a cushioning feeling in a cotton or bulge shape. Particularly, the second nonwoven fabric 25 is impregnated or combined with a synthetic resin such as PET, so that the trim component 2 of the second step, that is, the injection pressure at the injection injection S300 and the shear of the wood, Thereby protecting the foil material 10.

In particular, the second nonwoven fabric 25 and the synthetic resin prevent the local flexed or curved shape of the trim piece 2 made through the insert injection S300 from being restored to its original smooth or nearly smooth condition, Can be used as a means to help maintain the shape and maintain the design reproducibility of the trim part in the rear injection process.

In addition, since the trim-forming composite foil 100 wound in a roll shape maintains the coating quality and surface texture quality required by the application even after the insert injection step S300, The part 2 can be immediately mounted to the corresponding trim joint without additional post-processing (e.g., separate coating or surface processing).

7 is an enlarged cross-sectional view of the circle A shown in Fig.

Referring to FIG. 7, the trim composite foil 100 may be layered along the foil thickness direction by the first step, that is, the steps described below, to form a layer by component.

For example, the trim composite foil 100 includes a second nonwoven fabric 25 disposed at the lowermost position thereof and coalesced with a synthetic resin to have a thickness of 0.1 mm, and a second nonwoven fabric 25 laminated to the second nonwoven fabric 25, A synthetic resin layer 110 (e.g., PET layer) having the same thickness as the synthetic resin, a first nonwoven fabric 20 integrated with the synthetic resin layer 110 and having a thickness of 0.05 to 0.08 mm, And a foil material 10 which is incorporated into the first nonwoven fabric 20 through a hot press and has a thickness of 0.25 to 0.3 mm which is controlled by a sanding step as a natural fiber sheet or wood.

Here, the foil material 10 is incorporated in the first nonwoven fabric 20, the synthetic resin layer 110 and the second nonwoven fabric 25 so that the foil material 10 is prevented from being deformed excessively due to inherent properties of the natural fiber sheet or wood material, It can be in a state of being modified by physical properties such that the shape can be fixed.

The trim composite foil 100 may be formed on the upper surface of the foil material 10 and may have a thickness of 30 to 35 탆 and may have a mixing color or may include a transparent surface modification layer 120.

In addition, the trim composite foil 100 may include a first coating layer 130 coated on the upper surface of the surface modification layer 120 with a mild or glossy coat. Also, the first coating layer 130 may have a thickness of 25 to 30 占 퐉.

Here, the surface modification layer 120 may serve as a primer layer for bonding with the first coating layer 130, or may be a kind of undercoating material used as a means for enhancing the color feeling of the foil material 10 or for increasing the surface thereof Or a luminescent coating agent.

In addition, the trim composite foil 100 includes a second coating layer 140 that is top clear coated on the upper surface of the polished first coating layer 130. Here, the second coating layer 140 may have a thickness of 20 to 25 탆.

The trim composite foil 100 may be further laminated with a removable protective film 150 on top of the second coating layer 140.

In particular, the above-mentioned values for the thickness may be the surface texture of an actual wood or natural fiber sheet, or an optimized number obtained through experimentation to reveal a deep and classic sense of quality. If the corresponding thickness of the trim composite foil 100 is smaller than the above numerical range, the foil material 10 may cause quality problems such as breakage by an external force. On the other hand, It is not possible to delay the natural surface texture of the wood, so that the numerical value or numerical range is a critical value.

The layered composite foil 100 of such a layer structure may be bent or twisted or sharply folded, and the foil material 10 itself may be modified or reinforced so that it is not damaged.

The thickness of the trim composite foil 100 excluding the thicknesses of the surface modification layer, the first and second coating layers 120, 130 and 140 and the protective film 150 may be 0.6 to 0.8 mm.

Since the trim composite foil 100 has a thickness of 1 mm or less even if it includes the surface modification layer and the first and second coating layers 120, 130 and 140, the trim composite foil 100 can be used to manufacture trim parts , It is molded to form an obtuse angle or an acute angle, including a right angle close to the radius curvature 1 of the bent part of the trim piece, and the formed state can be maintained without restoring.

Here, the radius of curvature is the radius of curvature, and the inverse of the radius of curvature is called radius of curvature. That is, if the curvature radius is 'r', the curvature is 'r / 1'. As a comparative example, the radius of curvature of the material for trim is 6 or more.

The protective film 150 of the trim composite foil 100 is a film having a tacky adhesive removably at the upper portion of the second coating layer 140. Here, the protective film 150 may have a thickness of 38 to 80 탆. In addition, the protective film 150 is provided with a pressure-sensitive adhesive, and may be detachably attached to the second coating layer 150 and may not easily fall off, and may be separated by a force of an attractive force as the case may be.

Hereinafter, a specific manufacturing method according to the present embodiment will be described in detail.

8 is a flowchart for explaining a process of manufacturing the trimmed composite foil shown in FIG. 6 in the form of a roll.

The manufacturing method of the trimmed composite foil according to the present embodiment can be described with reference to FIGS. 1 and 8. FIG.

The manufacturing method of this embodiment includes a step S101 of preparing a first nonwoven fabric 20 for back joining and a step of preparing a foil material 10 which is a natural fiber sheet or wood to be bonded to the first nonwoven fabric 20 by hot press (S102).

Step S101 of preparing the first nonwoven fabric 20 and step S102 of preparing the foil material 10 may be overlapped with each other and prepared for use in the hot press apparatus 303. [

After the step S101 of preparing the first nonwoven fabric 20 or the step S102 of preparing the foil material 10, a hot pressing step S103 is performed.

The hot press step S103 is a step of applying heat and pressure to the first nonwoven fabric 20 and the foil material 10 by the hot press apparatus 303 so that the first nonwoven fabric 20 and the foil material 10 are laminated To form the foil base material S1.

The hot press apparatus 303 can form the foil base material S1 by pressing the first nonwoven fabric 20 and the foil material 10 stacked on the workbench in the thickness direction and transferring heat to join or coalesce them.

The hot press apparatus 303 removes the formaldehyde, moisture, and the like contained in the foil material 10 by carbonization to produce an environmentally friendly foil material S1.

The hot press apparatus 303 presses the first nonwoven fabric 20 and the foil material 10 at a temperature of 130 to 140 占 폚 for 3 to 4 minutes.

After the hot pressing step S103, a guillotine step S104 is performed in which the foil base material S1 is cut in the longitudinal direction to make the base material dividing parts S2 and S3.

Guillotine can be performed by a cutting device 304 that processes the foil base material S1 into a narrow material form part S2, S3 in comparison with its length.

After the guillotine step S104, the parent material dividing parts S2 and S3 are connected to each other, and the connected parent material dividing parts S2 and S3 are wound to form the roll type foil master material S4. S105). The finger joining step (S105) is performed by a conventional finger joining device (305).

In the finger joining step S105, the cut base material dividing parts S2 and S3 cut to the same width and processed to be finger-joined are connected and extended to each other via the finger joining device 305, The foil base material S4 rolled in roll form by the recovery device 306 is produced.

Thus, the foil base material S4 in the roll form passes through the sanding device 307 and undergoes the sanding step S106.

In the sanding step S106, the roll-shaped foil base material S4 is unwound and flows into the sanding device 307. [ Thereafter, the surface of the foil material 10 of the foil base material S4 is processed in a sanding manner, so that the foil base material S5 having the thickness of the foil material 10 adjusted to a predetermined value is produced. For example, the thickness of the foil material 10 of the foil base material S5 through sanding can be adjusted to a predetermined value, that is, a thickness of 0.25 to 0.3 mm.

Thereafter, a lamination step S107 is performed in which the extruded liquid synthetic resin is injected between the sanded foil base material S5 and the second nonwoven fabric 25 to form the foil laminated material S6.

The laminating step S107 may be realized by the extrusion die die laminating apparatus 310 described in detail with reference to Fig.

The foil laminate S6 after the laminating step S107 has a surface modification layer on the top surface of the foil laminate S6 through the surface modification layer formation step S108.

The surface modification layer forming step (S108) may be realized by the surface modification apparatus 320 described above with reference to FIG.

According to the surface modification layer forming step S108, the brush roller 321 provided in the surface modification apparatus 320 is supplied with a raw material for a surface modification layer, such as a mixing color coating material or a transparent adhesive, And the raw material for the surface modification layer is applied to the upper surface of the foil laminate S6.

The air knife 322 provided in the surface modifying apparatus 320 as a downstream end of the brush roller 321 injects the high pressure air supplied from the compressor to the raw material for the surface modifying layer in the applied state, The raw materials for the layer are adjusted smoothly.

The dryer 333 disposed at the rear end of the air knife 322 dries the smoothed surface modification layer raw material, and as a result, a surface modification layer such as a primer layer, such as a primer layer, is formed in the foil laminate S7.

At this time, the foil laminate S7 can be dried by heated air at a temperature of 70 to 80 DEG C while moving at a moving speed of 5 to 7 m / min.

The foil laminate S7 having undergone the surface modification layer formation step S108 has a first coating layer through the first coating step S109.

The first coating step S109 may be realized by the first coating apparatus 330 described above.

According to the first coating step (S109), the foil laminate S7 having the surface modification layer enters the first coating unit 323 (see FIG. 3) of the first coating apparatus 330.

The first coating liquid supply device in the form of a spray nozzle provided in the first coating unit 323 is configured to supply a first coating liquid such as a middle mat or a bright coating to the upper surface of the surface modification layer of the foil laminate S7 through a spray nozzle Coating (e. G., A first coating).

Thereafter, the foil laminate S7 having the first coating liquid applied thereon moves obliquely at a moving speed of 5 to 7 m / min along a feed roll 324a (see Fig. 3) arranged so as to have an upward slope and a downward slope, It can be dried by heated air at 70 to 80 ° C.

Further, the dried foil laminate S7 is subjected to the polishing step S110 via the polishing apparatus 340. [

In the polishing step S110, the first coating layer is polished by the polishing apparatus 340 to maintain a smoother and more beautiful surface, and the thickness of the first coating layer can be maintained at about 25 to 30 占 퐉.

Further, the foil laminated material S9 that has passed through the polishing apparatus 340 is conveyed to the second coating apparatus 330 side.

The foil laminate S9 having undergone the polishing step S110 has a second coating layer through the second coating step S111.

The second coating step S111 may be realized by the second coating apparatus 350 described above.

According to the second coating step S111, the second coating liquid supply device in the form of a spray nozzle provided in the second coating unit 353 (see FIG. 4) of the second coating device 350 is supplied with a coating agent 2 coating liquid is supplied to the upper portion of the first coating layer of the foil laminate S9 through a spray nozzle.

Thereafter, the foil laminate S9 coated with the second coating liquid is also moved obliquely at a moving speed of 5 to 7 m / min along a conveying roll 354a (see Fig. 4) arranged so as to have an upward slope and a downward slope, It can be dried by heated air at 70 to 80 ° C.

In addition, the dried foil laminate S10 passes through a laminating device 355 provided at the rear end of the second coating apparatus 350. [

At this time, the lapping device 355 laminates the protective film 150 on the second coating layer of the foil laminate S9. That is, a protecting film laminating step S112 is performed in which the detachable protective film 150 is provided on the second coating layer.

The protective film lamination step S112 may be performed by the corresponding lamination device 355 shown in Fig. 4, and finally the trim composite foil 100 can be completed.

Fig. 9 is a photograph showing a comparative example of a trim part made of a trim-forming composite foil manufactured through the steps shown in Fig. 8 and a photograph of a comparative example of the embodiment and a comparative example of the trim part shown in Fig. 11 is an enlarged photograph of circle B shown in Fig.

The comparative example of FIG. 9 (a) has a disadvantage in that the bent part of the trim part after the insert injection is returned to its original smooth shape, in which the trim part is made by the adhesive reverse impregnation method.

On the other hand, the embodiment of FIG. 9 (b) is the trim part 2 manufactured by the above-described method of manufacturing the trimmed composite foil. Particularly, even if the radius of curvature of the bent part of the outer edge of the trim part 2 is subjected to insert injection, it can be formed to be relatively smaller than that of the outer part of the comparative example (a). Further, after the insert injection, the molded state of the trim part 2 is not restored to the flattened original state, but is maintained as it is.

That is, referring to the back surface of the comparative example of Fig. 10 (a), since the back surface reinforcement material of the release material is simply provided on the back surface thereof, as described above, the bent part of the trim part after the insert injection is originally smooth I will go back.

On the other hand, referring to the embodiment of FIG. 10 (b), the rear surface of the trim part 2 of the present embodiment is formed by laminating the extruded liquid synthetic resin between the second nonwoven fabric and the foil material (Refer to the enlarged view of Fig. 10), and accordingly, the molded state after the insert injection can be maintained without being restored.

11, according to the modified surface structure, the polyester nonwoven fabric component is impregnated into the PET component on the back surface of the trim composite foil or on the back surface of the trim component 2, A synthetic resin nonwoven fabric is formed. Here, the synthetic resin nonwoven fabric composite has a surface texture such as a cuticle or a crystal.

The back surface of the trim component 2 is reinforced with an altered surface structure having a surface texture such as this cuticle. The front surface of the trim component 2 is protected by a surface modification layer and a plurality of coating layers. That is, the trim piece 2 can completely satisfy the technical quality required by the set maker that manufactures or uses the trim piece 2. For example, the cooled trim component 2 after the insert injection can maintain its molded shape and can produce the same texture and quality as actual wood or natural fibers.

In addition, even if an external force acts on the trim component 2, the elasticity can be exerted due to the structural characteristics of the synthetic resin nonwoven fabric assembled with the polyester nonwoven fabric component and the PET component.

Namely, as shown in Figs. 9 and 10 (b) and Fig. 11, the trimmed composite foil completed by the manufacturing method of this embodiment has a separate coating or surface processing The molding condition can be maintained untouched without being required, and it can be maintained as is without restoring the actual natural wood or gypsum or natural fiber sheets of foil material such as sheep, jute, hemp, flax, moss, , A material made by pressing a thin layer of sisal gum and bouillon into a sheet form) has the same surface texture as that of the actual material, but a three-dimensional shape can be realized without any damage such as breakage before and after insert injection.
