도 1은 본 발명에 의한 CPP 필름을 사용한 시트의 실시예를 도시한 사시도이다.1 is a perspective view showing an embodiment of a sheet using a CPP film according to the present invention.

도 2는 본 발명에 의한 CPP 필름을 사용한 시트의 단면도이다.2 is a cross-sectional view of a sheet using a CPP film according to the present invention.

본 발명은 CPP 필름을 사용한 시트의 제조방법 및 그에 의해 제조된 시트에 관한 것으로서, 보다 상세하게는 종래의 시트를 제조할 시 사용되던 PVC 대신에 인체에 무해하고 친환경적인 CPP 필름을 사용하여 건축자재 및 가구의 외면에 장식용 등으로 활용되는 CPP 필름을 사용한 시트의 제조방법 및 그에 의해 제조된 시트에 관한 것이다.The present invention relates to a method for producing a sheet using a CPP film and to a sheet produced by the same, more specifically, building materials using CPP film, which is harmless to the human body and is environmentally friendly, instead of PVC, which is used in manufacturing a conventional sheet. And it relates to a method for producing a sheet using a CPP film used for decoration and the like on the outer surface of the furniture and the sheet produced thereby.

종래에는 제품을 포장하는 포장재나, 가구 등의 표면에 사용하는 표면재로서 PVC(Polyvinyl Chloride)를 널리 사용하였다. 그러나, 상기 PVC에서는 인체에 유해한 환경호르몬이 검출될 뿐만 아니라, PVC 제품을 생산하는 과정에서는 발암물질인 프탈산계 가스가 발생하며, PVC를 소각하는 과정에서는 다이옥신이 발생하여 인 체에 해로운 영향을 끼친다는 문제점이 있었다. Conventionally, PVC (Polyvinyl Chloride) has been widely used as a packaging material for packaging a product or a surface material used for the surface of furniture. However, in the PVC, not only environmental hormones that are harmful to the human body are detected, but phthalic acid gas, which is a carcinogen, is generated in the process of producing PVC products, and dioxin is generated in the process of incineration of PVC, which has a detrimental effect on the human body. Had a problem.

따라서, 상기 PVC에 대체할 수 있는 CPP(Cast Polypropylene) 필름의 사용이 늘어나고 있다. CPP 필름은 PP(Polypropylene)를 무연신으로 T-다이(die) 공법을 사용하여 제조한 필름을 말한다. 상기 CPP 필름은 투명하고 광택이 있으나, 상기 투명도나 광택이 OPP 필름에 비하여 다소 떨어진다. 그러나, OPP 필름에 비하여 저온 충격강도 및 열 봉합성이 우수하여, 상기 CPP 필름을 OPP 필름 또는 PET 필름과 합지하면 우수한 방습성을 가지게 된다는 특징이 있다. 이러한 특징을 가진 CPP 필름은 그 투명성, 표면광택도 및 기계적 강도가 우수하여 빙과, 스낵, 쿠키 등의 방습성 식품의 포장재의 차별화를 위하여 많이 활용되고 있으며, 인쇄용으로도 사용이 가능하다. 또한, 무광 CPP 필름은 잡지 등의 겉표지 코팅용으로도 많이 사용되고 있다.Therefore, the use of CPP (Cast Polypropylene) film that can replace the PVC is increasing. The CPP film refers to a film produced by using a T-die method without drawing polypropylene (PP). The CPP film is transparent and glossy, but the transparency or gloss is somewhat inferior to that of the OPP film. However, it is excellent in low-temperature impact strength and heat sealability as compared to the OPP film, it is characterized in that the CPP film is laminated with the OPP film or PET film has excellent moisture resistance. CPP film having such characteristics is excellent in its transparency, surface gloss and mechanical strength, and is widely used for differentiating packaging materials of moisture-proof foods such as frozen desserts, snacks, and cookies, and can also be used for printing. In addition, the matte CPP film is also widely used for coating the cover of magazines and the like.

그러나, 이러한 CPP 필름은 제품의 표면장력으로 인해 장식용 시트 등으로 제조할 시 인쇄작업이나 접착작업에서 어려움이 있다는 문제점이 있었으며, 제품의 표면강도와 물성이 떨어져 약한 충격에도 쉽게 스크레치 등이 발생한다는 문제점이 있었다.However, the CPP film has a problem in that it is difficult in printing or bonding work when manufacturing the decorative sheet due to the surface tension of the product, and scratches easily occur even in a weak impact due to the product's surface strength and physical properties. There was this.

따라서, 본 발명의 목적은 상기와 같은 종래기술의 문제점을 해결하기 위한 것으로서, CPP 필름을 이용하여 시트를 제조할 시, CPP 필름의 표면장력을 조절하여 인쇄작업 및 접착작업이 원활히 이루어질 수 있도록 하였으며, 시트의 표면에 표면 처리제로 코팅하여 시트의 경도를 높여 스크래치 등의 발생을 최소화하는 CPP 필름을 사용한 시트의 제조방법 및 그에 의해 제조된 시트를 제공하고자 하는 것이다.Therefore, an object of the present invention is to solve the problems of the prior art as described above, when manufacturing a sheet using a CPP film, by adjusting the surface tension of the CPP film to facilitate the printing and bonding work. To improve the hardness of the sheet by coating the surface of the sheet with a surface treatment agent to provide a method for producing a sheet using a CPP film to minimize the occurrence of scratches, and the sheet produced thereby.

여기에서, 상기 1차 숙성 및 2차 숙성은 55~65℃의 온도에서 40~50시간 동안 이루어지며, 상기 표면 처리제는 아크릴계 2액형 처리제인 것을 특징으로 한다.Here, the primary aging and secondary aging is made for 40 to 50 hours at a temperature of 55 ~ 65 ℃, the surface treatment agent is characterized in that the acrylic two-component treatment agent.

또한, 상기 방법에 의하여 제조되는 CPP 필름을 사용한 시트는 프라이마층; 상기 프라이마층의 상면에 위치한 백색 CPP 합성지층; 상기 백색 CPP 합성지층의 상면에 위치한 인쇄층; 상기 인쇄층의 상면에 위치한 접착제층; 상기 접착제층의 상면에 위치한 CPP 필름층; 및 상기 CPP 필름층 상면에 위치한 표면층을 포함한다.In addition, the sheet using the CPP film produced by the method comprises a prima layer; A white CPP synthetic layer located on the top of the prima layer; A printing layer located on an upper surface of the white CPP synthetic paper layer; An adhesive layer located on an upper surface of the printed layer; A CPP film layer located on an upper surface of the adhesive layer; And a surface layer located on an upper surface of the CPP film layer.

여기에서, 상기 시트는 그 두께가 0.05~1.0mm인 것을 특징으로 한다. Here, the sheet is characterized in that the thickness of 0.05 ~ 1.0mm.

이하, 도면을 참조하여 본 발명에 따른 CPP 필름을 사용한 시트의 제조방법 및 그에 의해 제조된 시트를 보다 상세히 설명하면 다음과 같다.Hereinafter, a method of manufacturing a sheet using a CPP film according to the present invention and a sheet manufactured by the method will be described in detail with reference to the accompanying drawings.

도 1에 도시된 본 발명의 CPP 필름을 사용한 시트(10)를 제조하기 위해서는 먼저, 시트의 기본이 되는 백색 CPP 합성지(12)를 준비하고, 이를 코로나 처리한다. In order to manufacture the sheet 10 using the CPP film of the present invention shown in FIG. 1, first, a white CPP synthetic paper 12, which is the basis of the sheet, is prepared and subjected to corona treatment.

이때 코로나 처리란, 상기 CPP 필름의 매끄러운 표면의 표면장력을 좋게 하여 특수잉크 등이 점착되는 특성을 갖도록 하기 위한 공정으로서, 코로나 처리를 하지 않은 CPP 합성지의 표면장력은 28~30dyne인 반면, 코로나 처리가 완료된 CPP 합성지의 표면장력은 40~41dyne이다.In this case, the corona treatment is a process for improving the surface tension of the smooth surface of the CPP film so that special ink, etc. are adhered. The surface tension of the CPP synthetic paper without corona treatment is 28 to 30 dyne, while the corona treatment is performed. The surface tension of CPP synthetic paper is 40 ~ 41dyne.

상기 코로나 처리를 거친 백색 CPP 합성지(12)의 이면에 접착제인 프라이마(11)를 도포한다. 상기 프라이마(11)를 도포함으로써, 시트를 사용할 시, 상기 시트가 MDF(Medium Density Fiberboard), P/B 또는 합판 등에 완전히 접착되지 않고 박리되는 현상을 방지할 수 있으며, 접착 강도가 우수하여 2차 가공 상에 문제가 없게 된다. On the back surface of the corona treated white CPP synthetic paper 12 is applied a primer 11, which is an adhesive. By applying the prima 11, when the sheet is used, the sheet can be prevented from being peeled off without being completely adhered to MDF (Medium Density Fiberboard), P / B or plywood, and the adhesive strength is excellent. There is no problem in tea processing.

또한, 본원발명에서는 프라이마 처리 후, 후속하여 인쇄, 접착 작업 및 표면 처리 작업을 한번에 처리함으로써, 종래의 사용하는 방법인 인쇄, 접착 작업 및 표면 처리 작업을 실시한 후, 다시 프라이마 처리를 하는 2단계로 나누어지는 공정과 달리, 시간이 절약될 뿐만 아니라, 불량품의 생산을 줄일 수 있어 생산비용을 절감할 수 있는 특징이 있다.In addition, according to the present invention, after the prima treatment, subsequent printing, bonding operations and surface treatment operations are performed at once, and after performing the printing, bonding operations and surface treatment operations which are conventional methods, Unlike the process divided into stages, not only saves time, but also reduces the production of defective products, there is a feature that can reduce the production cost.

이때, 상기 프라이마를 도포할 때에는 110~130메쉬 롤을 사용하며, 코로나 처리를 동시에 실시하도록 한다. 코로나 처리시 사용하는 처리제는 우레탄 계통인 것이 바람직하다.At this time, when applying the prima 110 to 130 mesh roll is used, and to perform the corona treatment at the same time. It is preferable that the processing agent used at the time of corona treatment is a urethane system.

다음, 상기 프라이마 처리가 완료된 백색 CPP 합성지(12)의 상면에 필요한 색상의 잉크를 전사하여 인쇄층(13)을 형성한다. 상기 백색 OPP 합성지(12)는 40~41dyne의 표면장력을 유지하고 있으며, 표면장력이 약 39dyne으로 유지된 상태에서 특수잉크를 사용하여 인쇄작업을 하도록 한다. 일반적으로 인쇄작업 및 접착작업에서 요구되는 적합한 표면장력은 38dyne이다.Next, the printing layer 13 is formed by transferring the ink of the required color onto the upper surface of the white CPP synthetic paper 12 on which the prima treatment is completed. The white OPP synthetic paper 12 maintains the surface tension of 40 ~ 41 dyne, and the printing operation using a special ink while the surface tension is maintained at about 39 dyne. In general, the suitable surface tension required for printing and bonding operations is 38 dynes.

여기에서, 인쇄작업시 사용되는 잉크는 일반적인 잉크와는 달리, 상기 백색 OPP 합성지(12)에 알맞는 특수잉크를 사용하여, 다음 공정에서 부착성에 문제가 없도록 한다. 이때, 상기 특수잉크의 구성성분은 안료, 수지, MEK (Methylethylketon), EA (Ethylacetate) 및 이소프로필알콜 (IPA)이다.Here, the ink used in the printing operation, unlike the general ink, uses a special ink suitable for the white OPP synthetic paper 12, so that there is no problem of adhesion in the next process. At this time, the constituents of the special ink are pigment, resin, MEK (Methylethylketon), EA (Ethylacetate) and isopropyl alcohol (IPA).

또한, 그라비아 인쇄시 나이트의 각도를 눕혀서 작업함으로써 특수잉크의 인쇄효과를 장기간동안 지속할 수 있다.In addition, the printing effect of special ink can be maintained for a long time by working with the angle of knight lying down when printing gravure.

다음, 인쇄작업이 완료된 인쇄층(13)의 상면에 접착제(14)를 도포한 후, 여기에 무광 CPP 필름(15)을 접착시킨다. 이 단계에서도 상기 무광 CPP 필름(15)의 표면장력을 향상시키기 위하여 상기 백색 CPP 합성지에서와 같이 코로나 처리를 하도록 한다.Next, after the adhesive 14 is applied to the upper surface of the printing layer 13 is completed, the matte CPP film 15 is adhered thereto. In this step, the corona treatment is performed as in the white CPP synthetic paper to improve the surface tension of the matte CPP film 15.

상기 CPP 필름(15)의 접착공정이 끝나면, 이를 55~65℃에서 40~50시간 동안 행거에 걸어 보관하면서 숙성시킨다. 숙성과정이 끝나면, 상기 접착제가 완전히 경화된다.After the adhesion process of the CPP film 15 is finished, it is aged while kept in a hanger for 40-50 hours at 55 ~ 65 ℃. At the end of the aging process, the adhesive is fully cured.

숙성이 완료되면 시트의 표면을 보호하기 위하여, 상기 CPP 필름(15)의 상면에 표면 처리제를 코팅하여 표면층(16)을 형성한다. 이때, 상기 표면 처리제로는 친환경적인 메틸이소부틸케톤 (MIBK) 및 이소프로필알콜 (IPA)을 사용한다.When the aging is completed, in order to protect the surface of the sheet, a surface treatment agent is coated on the upper surface of the CPP film 15 to form a surface layer 16. In this case, as the surface treatment agent, environmentally friendly methyl isobutyl ketone (MIBK) and isopropyl alcohol (IPA) are used.

또한, 코팅시에는 110~130메쉬 롤을 사용하며, 코팅공정이 완료된 후, 40~50시간 동안 숙성시켜 표면층의 물성이 유지되어 내오염성 및 내용제성이 향상되도록 한다. In addition, 110 to 130 mesh rolls are used for coating, and after the coating process is completed, aging for 40 to 50 hours to maintain the physical properties of the surface layer to improve pollution resistance and solvent resistance.

표면 코팅처리를 하지 않으면 CPP 필름의 경도가 약해, 2차 가공시 가벼운 충격에 의해서도 표면에 스크레치 등이 쉽게 발생하는 문제점이 있다. If the surface coating is not performed, the hardness of the CPP film is weak, and there is a problem that scratches are easily generated on the surface even by a light impact during the secondary processing.

상기와 같은 제조공정을 통하여 완성된 CPP 필름을 사용한 시트는 도 1에 도시된 바와 같이, 하단에 위치한 프라이마층(11), 상기 프라이마층(11)의 상면에 위치한 백색 CPP 합성지층(12), 상기 백색 CPP 합성지층(12)의 상면에 위치한 인쇄층(13), 상기 인쇄층(13)의 상면에 위치한 접착제층(14), 상기 접착제층(14)의 상면에 위치한 CPP 필름층(15) 및 상기 CPP 필름층(15) 상면에 위치한 표면층(16)을 포함하고 있으며, 시트(10)의 두께는 0.05~0.10mm인 것이 바람직하며, 그 용도 및 사용 부위에 따라 시트의 두께를 조절하여 0.5~1.0mm로 제조될 수도 있다. 또한, 시트의 규격 역시 0.1~1.0mm로 조절이 가능하다.As shown in FIG. 1, the sheet using the CPP film completed through the manufacturing process as described above has a prima layer 11 located at the bottom and a white CPP synthetic paper layer 12 located at the top of the prima layer 11. ), A printing layer 13 located on the top surface of the white CPP synthetic paper layer 12, an adhesive layer 14 located on the top surface of the printing layer 13, and a CPP film layer located on the top surface of the adhesive layer 14 ( 15) and the surface layer 16 located on the upper surface of the CPP film layer 15, the thickness of the sheet 10 is preferably 0.05 ~ 0.10mm, the thickness of the sheet is adjusted according to the purpose and site of use It may be manufactured to 0.5 ~ 1.0mm. In addition, the size of the sheet can also be adjusted to 0.1 ~ 1.0mm.

이러한 시트는 기존의 PVC를 표면재로 사용하는 건축 자재 및 가구의 내·외면에 사용되며, 몰딩도어 및 오바레이에도 사용이 가능하다.These sheets are used for interior and exterior surfaces of building materials and furniture that use conventional PVC as surface materials, and can also be used for molding doors and overlays.

본 발명에 의한 CPP 필름을 사용한 시트의 제조방법에 의하면, 인쇄작업 및 접착작업시 CPP 합성지의 표면장력을 적절히 유지하고, 특수잉크를 사용함으로써, 필요한 색을 가진 시트의 제조가 가능할 뿐만 아니라, 접착성도 뛰어나다는 장점이 있다.According to the manufacturing method of the sheet using the CPP film according to the present invention, by maintaining the surface tension of the CPP synthetic paper appropriately during printing and bonding operations, and using a special ink, not only the sheet having the required color can be manufactured, but also the adhesive It also has the advantage of superiority.

또한, CPP 필름을 사용한 시트의 제조시, 시트의 표면을 보호하기 위하여 표면 처리제를 코팅함으로써, 경도가 약한 CPP 필름을 보호하여 충격이 가하여져도 스크래치 등이 발생하지 않을 뿐만 아니라, 내오염성과 내용제성 또한 우수하다는 장점이 있다.In addition, when manufacturing a sheet using a CPP film, by coating a surface treatment agent to protect the surface of the sheet, not only scratches are generated even when an impact is applied to protect the CPP film of low hardness, but also stain resistance and solvent resistance. It also has the advantage of being excellent.

또한, 시트를 제조하는 공정에서, 먼저 프라이마 처리를 한 후, 후속하여 인쇄, 접착 작업 및 표면 처리 작업을 한번에 처리함으로써, 시간이 절약될 뿐만 아니라, 불량품의 생산을 줄일 수 있어 생산비용을 절감할 수 있는 장점이 있다.In the sheet manufacturing process, the prima treatment is performed first, followed by the printing, bonding, and surface treatment at once, which not only saves time but also reduces the production of defective products, thereby reducing production costs. There is an advantage to this.

또한, 포장재의 주요 구성성분으로 사용되던 기존의 다이옥신 등의 환경호르몬을 방출하는 PVC가 아닌, 친환경적인 CPP 필름으로 장식용 시트를 제조함으로써 인체에 유해한 영향을 끼치지 않을 뿐만 아니라, 가격도 기존의 PVC 제품에 비하여 10~20% 정도 저렴하여 보다 대중적으로 이용될 수 있다는 장점이 있다.In addition, by manufacturing decorative sheets from environmentally friendly CPP films, not PVC, which emits environmental hormones such as dioxins, which were used as the main components of packaging materials, not only does not have a harmful effect on human body, but also the price of conventional PVC Compared with the product, it is 10 to 20% cheaper and can be used more popularly.
