And a manufacturing method thereof.

일반적으로, 자동차 내부는 제2의 주거공간으로 인식되고 있으며, 최근에는 이러한 자동차 내부 공간에서 편안하고 쾌적한 운전을 위해 기능성 시트가 각광받고 있다.In general, the inside of a car is recognized as a second residential space, and recently, a functional seat has been spotlighted for comfortable and comfortable driving in the interior space of such a car.

자동차 내장재용 소재로는 천연가죽이나 PVC, PU 인조가죽이 주로 사용된다. 인조가죽은 천연가죽에 비해 저렴한 장점이 있다. 이러한 인조가죽에 대하여 대한민국 공개특허 제10-2009-0095044호(공개일: 2009년09월09일) 등으로 선 출원된 바 있다.Natural leather, PVC, PU artificial leather are mainly used for automobile interior materials. Artificial leather is less expensive than natural leather. Such artificial leather has been filed in Korean Patent Application No. 10-2009-0095044 (published on September 09, 2009).

기존의 인조가죽은 안료를 통해 색을 부여하고 있으며, 대부분 검정과 베이지 색상이 주를 이루고 있다. 즉 안료 사용의 한계로 인조가죽에 포인트를 줄 수 있는 색이나 디자인을 구현하는데 한계가 있다.Existing artificial leather is given color through pigment, mostly black and beige color. In other words, there are limitations in implementing colors and designs that can give points to artificial leather due to limitations of pigment usage.

이에 따라 인조가죽에 다양한 색이나 디자인을 부여할 수 있도록 인조가죽의 표지층 상에 증착 공정을 이용한 금속증착층을 적층하기도 하였다.Accordingly, a metal deposition layer using a deposition process is laminated on a label layer of artificial leather so as to give various colors or designs to artificial leather.

상기 금속증착층을 적층한 후에는 최종적으로 금속증착층의 표면에 표면처리제 코팅과정을 거침으로써 인조가죽의 질감을 가죽과 비슷하게 향상시킬 수 있다.After the metal deposition layer is laminated, the surface of the metal deposition layer is finally coated with the surface treatment agent, thereby improving the texture of the synthetic leather similar to leather.

그러나 상기와 같은 표면처리 과정에서 금속증착층에 적층되는 표면처리층의 밀착력이 약해 표면이 손상되어 자국이 남거나, 박리현상이 발생하게 되는 등의 문제점이 있다.However, in the surface treatment process described above, there is a problem that the adhesion of the surface treatment layer laminated on the metal deposition layer is weak and the surface is damaged, so that marks are left or peeling phenomenon occurs.

여기서, 각 도면의 구성요소들에 대해 참조부호를 부가함에 있어서 동일한 구성요소들에 한해서는 비록 다른 도면상에 표시되더라도 가능한 한 동일한 부호로 표기되었음에 유의하여야 한다.In the drawings, the same reference numerals as in the drawings denote the same elements in the drawings, unless they are indicated on other drawings.

도 1은 본 발명에 따른 금속증착층이 구비된 인조가죽의 적층구조를 보여주는 측단면도이고, 도 2 내지 도 4는 본 발명에 따른 금속증착층이 구비된 인조가죽의 제조과정을 보여주는 도면이다.FIG. 1 is a side sectional view showing a laminated structure of artificial leather provided with a metal vapor deposition layer according to the present invention, and FIGS. 2 to 4 are views showing a process of manufacturing artificial leather provided with a metal vapor deposition layer according to the present invention.

도 1을 참조하면, 본 발명의 바람직한 일 실시예에 따른 인조가죽(100)은, 아래에서 위로 직물층(110), 발포층(120), 표지층(130), 금속증착층(140), 표면처리층(150)을 포함한다.1, a synthetic leather 100 according to a preferred embodiment of the present invention includes a fabric layer 110, a foam layer 120, a label layer 130, a metal deposition layer 140, And a surface treatment layer 150.

이러한 본 발명의 구성에 대해 구체적으로 설명하면 다음과 같다.The configuration of the present invention will be described in detail as follows.

먼저, 직물층(110)은 직물, 니트, 함침 트리코트, 함침 부직포, 원착사, 부직포 중 어느 하나의 재질로 이루어질 수 있다.First, the fabric layer 110 may be made of any one of a fabric, a knit, an impregnated tricot, an impregnated nonwoven fabric, a raw fabric, and a nonwoven fabric.

발포층(120)은 직물층(110)의 상부에 적층되는 것으로, 발포수지 재질, 예컨대 PVC(polyvinyl chloride) 또는 PU(polyurethane) 소재로 이루어진 폼에 열 및 압력을 가하여 탈포시킨 연속 기포형 시트(opened cell sheet)로 구성될 수 있다.The foam layer 120 is laminated on the upper side of the fabric layer 110. The foam layer 120 is formed of a foamed resin material such as polyvinyl chloride (PVC) or polyurethane (PU) opened cell sheet).

이러한 발포층(120)을 연속 기포형 시트로 제조함으로써 기존의 독립 기포형 시트(closed cell sheet)를 사용함에 따라 발생된 굴곡탄성의 문제점을 해결함과 동시에 저밀도 특성으로 인조가죽 제품의 무게저감효과를 얻을 수 있다.By manufacturing the foamed layer 120 as an open celled sheet, the problem of bending elasticity caused by using a conventional closed cell sheet is solved, and at the same time, the weight reduction effect of the artificial leather product Can be obtained.

참고로, 직물층(110)과 발포층(120)은 드라이 본드 라미네이트 또는 핫멜트(Hot melt) 라미네이트에 의해 접착될 수 있다. 드라이 본드 라미네이트는 접착제를 도포하고 건조과정을 거친 후 접착물끼리 부착하는 방식이고, 핫멜트 라미네이트는 상온에서 유동성을 갖는 특성을 이용하여 열을 가한 후 냉각되면 고화 접착되는 방식이다.For reference, the fabric layer 110 and the foam layer 120 may be adhered by dry bond laminates or hot melt laminates. The dry bond laminate is a method in which the adhesive is applied and dried, and then the adhesive is adhered to each other. The hot-melt laminate is solidified by applying heat using the fluidity property at room temperature and then cooling it.

이 경우 상기 직물층(110)과 발포층(120) 이외에도 인조가죽(100)을 구성하는 각각의 층은 상기와 같은 접착방식을 통해 적층될 수 있다. 물론 이에 한정하지 않으며, 다양한 방식으로 변경 적용될 수 있다.In this case, in addition to the fabric layer 110 and the foam layer 120, each layer constituting the artificial leather 100 may be laminated through the above-described bonding method. However, the present invention is not limited thereto and can be applied in various ways.

도 2를 참조하면, 표지층(130)은 발포층(120)의 상부에 적층되는 것으로, PVC(polyvinyl chloride) 또는 PU(polyurethane) 재질로 이루어질 수 있다.Referring to FIG. 2, the label layer 130 is laminated on the foam layer 120 and may be made of polyvinyl chloride (PVC) or polyurethane (PU).

이상과 같은 직물층(110), 발포층(120), 표지층(130)의 재질 및 적층구조는 기존의 일반적인 인조가죽 제조과정과 유사함에 따라 이에 대한 자세한 설명은 생략하기로 한다.The material and lamination structure of the fabric layer 110, the foam layer 120, and the label layer 130 are similar to those of a conventional artificial leather manufacturing process, so a detailed description thereof will be omitted.

다시 도 1을 참조하면, 금속증착층(140)은 표지층(130)의 상부에 적층되는 것으로, 통상적인 진공증착(sputtering) 공정을 통해 증착 형성될 수 있다.Referring again to FIG. 1, the metal deposition layer 140 is deposited on the top of the label layer 130, and may be deposited through a conventional vacuum deposition (sputtering) process.

참고로, 진공증착은 진공상태의 용기 안에 헬륨 등 불활성 기체를 채워 코팅재료(타깃)에 고전압을 걸어 방전시키면 이온화된 불활성 기체가 코팅재료에 충돌하게 되고, 이때 타깃물질의 이온이 튀어나와 코팅 대상물에 달라붙어 코팅이 되는 원리를 이용한 일종의 물리증착기술을 말한다.For reference, in the vacuum deposition, when an inert gas such as helium is filled in a vacuum container and a high voltage is applied to a coating material (target) to discharge the ionized inert gas, the ions of the target material protrude from the coating material Which is a kind of physical vapor deposition technique using the principle of coating.

이러한 금속증착층(140)은 알루미늄, 구리, 은, 백금, 주석, 크롬, 니켈 중 하나 또는 둘 이상의 재질을 포함할 수 있다.The metal deposition layer 140 may include one or more of aluminum, copper, silver, platinum, tin, chromium, and nickel.

도 3을 참조하면, 본 발명에서는 금속증착층(140)을 표지층(130)의 상부에 직접 적층하지 않고 금속증착층(140)을 별도의 이형지(200) 상부에 증착 제조한 후, 상기 표지층(130)의 상부에 최종적으로 합지하는 방식으로 제조한다.3, the metal deposition layer 140 may be deposited on a separate release paper 200 without directly depositing the metal deposition layer 140 on the top of the label layer 130, Lt; RTI ID = 0.0 > 130 < / RTI >

좀 더 구체적으로 설명해보면, 종래기술에서 언급한 바와 같이 금속증착층(140)을 표지층(130)의 상부에 직접 증착하는 경우 표면처리 과정에서 금속증착층(140)의 상부에 적층되는 표면처리층(150)의 밀착력이 약해 표면이 손상되거나, 박리 현상이 발생할 수 있다.In more detail, when the metal deposition layer 140 is directly deposited on the upper surface of the label layer 130 as described in the related art, the surface treatment of depositing the metal deposition layer 140 on the upper surface of the metal deposition layer 140 The adhesion of the layer 150 is weak, so that the surface may be damaged or peeling may occur.

이를 방지할 수 있도록 본 발명에 따른 금속증착층(140)은, 먼저 이형지(200) 상부에 표면처리층(150)을 적층 형성하고, 표면처리층(150)의 상부에 증착 공정을 거쳐 금속증착층(140)을 적층하는 방식으로 별도의 증착지를 제조한다.The metal deposition layer 140 according to the present invention may be formed by laminating a surface treatment layer 150 on the release paper 200 and then depositing metal on the surface treatment layer 150, A separate deposition paper is produced in a manner that the layer 140 is laminated.

그리고 도 4 및 도 5에 도시된 바와 같이, 상기 별도로 제조된 증착지의 금속증착층(140) 부위를 표지층(130) 상부에 맞댄 후 합지시키는 방식으로 적층해준다. 이 경우 금속증착층(140)은 표지층(130)의 상부에 프라이머 또는 열을 이용하여 적층할 수 있다.Then, as shown in FIGS. 4 and 5, the metal deposition layer 140 of the separately prepared vapor deposition paper is laminated on the label layer 130 and then laminated. In this case, the metal deposition layer 140 may be laminated on the upper side of the label layer 130 using a primer or heat.

그런 후, 최종적으로 이형지(200)를 제거해주면 표면처리층(150)이 표면에 드러나게 되면서 도 1에서와 같은 본 발명에 따른 인조가죽(100)이 완성된다.Then, when the release paper 200 is finally removed, the surface treatment layer 150 is exposed on the surface, and the artificial leather 100 according to the present invention as shown in FIG. 1 is completed.

이 경우 상기 표면처리층(150)은 아크릴(acrylic) 또는 PU(polyurethane) 재질로 이루어질 수 있다.In this case, the surface treatment layer 150 may be made of acrylic or polyurethane (PU).

아울러 상기와 같은 적층구조의 인조가죽(100)은 표면 질감의 향상을 위해 상부 표면에 통상적인 엠보싱 공정을 거쳐 소정 디자인의 엠보(미도시)를 형성할 수 있다.In addition, the artificial leather 100 having the laminated structure as described above may be embossed (not shown) of a predetermined design through an ordinary embossing process on the upper surface to improve the surface texture.

그러면, 이상과 같은 구성의 본 발명에 따른 금속증착층이 구비된 인조가죽의 제조과정에 대하여 도 6을 참조하여 설명해보기로 한다. 도 6은 본 발명에 따른 금속증착층이 구비된 인조가죽의 제조과정을 보여주는 흐름도이다.Hereinafter, a process of manufacturing artificial leather provided with the metal deposition layer according to the present invention will be described with reference to FIG. 6 is a flowchart illustrating a process of manufacturing artificial leather provided with a metal deposition layer according to the present invention.

먼저, 아래에서 위로 직물층(110), 발포층(120), 표지층(130)을 순차적으로 적층한다(S1 ~ S3).First, the fabric layer 110, the foam layer 120, and the label layer 130 are sequentially stacked from the bottom (S1 to S3).

그런 다음, 별도로 준비된 이형지(200)의 상부에 표면처리층(150)을 적층한다(S4).Then, the surface treatment layer 150 is laminated on the separately prepared release paper 200 (S4).

표면처리층(150)의 상부에 진공증착(sputtering) 공정을 통해 금속증착층(140)을 적층한다(S5).The metal deposition layer 140 is deposited on the surface treatment layer 150 through a vacuum sputtering process (S5).

상기 금속증착층(140)을 상기 표지층(130)의 상부에 맞댄 후 합지시킨다(S6).The metal deposition layer 140 is brought into contact with the upper surface of the label layer 130 and is then joined together (S6).

그런 후, 최종적으로 이형지(200)를 제거해주면 본 발명에 따른 인조가죽(100)의 제조가 완성된다(S7).Thereafter, the release paper 200 is finally removed to complete the manufacture of the artificial leather 100 according to the present invention (S7).

도 7의 (a), (b)는 본 발명에 따른 금속증착층이 구비된 인조가죽과 종래의 인조가죽을 비교한 도면대용 실제사진이다. 7 (a) and 7 (b) are actual photographs showing a comparison between a synthetic leather having a metal deposition layer according to the present invention and a conventional artificial leather.

도 7에 도시된 바와 같이, 본 발명의 제조방법에 의해 제조된 인조가죽(200)을 종래의 인조가죽과 비교하였을 때, 도 7의 (a)에 도시된 종래의 인조가죽은 금속증착층 상에 표면 처리시 표면에 손상이 발생하였다.7, when the artificial leather 200 produced by the manufacturing method of the present invention is compared with conventional artificial leather, the conventional artificial leather shown in FIG. 7 (a) The surface was damaged during the surface treatment.

이에 반해 도 7의 (b)에 도시된 본 발명의 인조가죽(100)은 금속증착층(140)의 표면에 어떠한 손상이나 박리현상이 발생하지 않은 것을 알 수 있다.On the contrary, the artificial leather 100 of the present invention shown in FIG. 7 (b) does not show any damage or peeling on the surface of the metal deposition layer 140.

이상에서는 본 발명을 특정의 바람직한 실시 예를 들어 도시하고 설명하였으나, 본 발명은 상기한 실시 예에 한정되지 않으며 본 발명의 기술사상을 벗어나지 않는 범위 내에서 다양한 변경과 수정이 가능함은 물론이다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
