Description
본 발명은 PVC용 수성 그라비아 잉크에 관한 것으로, 상세하게는 유해 화학물질 없이 PVC를 녹이지 않고, 그라비아 인쇄가 되며 인쇄매체에 접착이 되는 PVC용 수성 그라비아 잉크 및 그의 제조방법에 관한 것이다. The present invention relates to water-based gravure ink for PVC, and more specifically, to a water-based gravure ink for PVC that does gravure printing without dissolving PVC without harmful chemicals and adheres to a printing medium, and to a method for manufacturing the same.
그라비아(Gravure) 인쇄란, 오목형태로 조각시킨 인쇄용 동판에 잉크를 묻혀 오목한 부분 이외의 것을 독타나이프로 제거하고, 오목한 부분에 들어있는 잉크를 필름에 인쇄하는 방법이다. Gravure printing is a method in which ink is applied to a printing copper plate carved into a concave shape, the parts other than the concave part are removed with a knife, and the ink contained in the concave part is printed on film.
그라비아 인쇄는 고속 인쇄가 가능하고, 활자, 문자, 도안 등의 재현성이 우수하기 때문에 대량 인쇄에 적합한 특징이 있다. 예컨대, PVC, PE, OPP, PET, NYLON 필름과 같은 포장용 필름에 그라비아 기법으로 인쇄층을 형성할 수 있다.Gravure printing is suitable for mass printing because it enables high-speed printing and has excellent reproducibility of types, characters, and designs. For example, a printing layer can be formed using the gravure technique on packaging films such as PVC, PE, OPP, PET, and NYLON films.
이러한 그라비아 인쇄는 유해화학물질 유기용제를 다량 사용하는 산업으로써, 탄화수소류의 배출규제, 소방법 및 산업안전보건법, 화학물질관리법의 법규제를 받고있는 등 그라비아 인쇄 업계를 둘러싼 환경은 점점 엄격해지고 있다.As gravure printing is an industry that uses large amounts of hazardous chemicals and organic solvents, the environment surrounding the gravure printing industry is becoming increasingly strict, including regulations governing hydrocarbon emissions, firefighting laws, the Occupational Safety and Health Act, and the Chemical Substances Control Act.
이같은 상황에서 국내외에서는 유해화학물질 사용을 규제하거나 아예 사용금지 하는 방향으로 각각의 법규제가 강화되고 있는 실정이다.In this situation, laws and regulations at home and abroad are being strengthened to regulate or completely ban the use of hazardous chemicals.
PVC에 인쇄하는 잉크는 부착력이 우수하고, 열합지가 가능하며, 내 마모성이 우수하고, 취기가 없으며, 내광성 및 내구성이 우수하여 인테리어, 바닥 리폼시트 등으로 다양하게 사용된다. The ink printed on PVC has excellent adhesion, can be heat laminated, has excellent wear resistance, has no odor, and has excellent light resistance and durability, so it is used in a variety of applications such as interior and floor reform sheets.
종래에는 PVC에 그라비아 인쇄를 작업할 때, 유해화학물질인 강용제가 들어있는 유성잉크로 PVC를 녹여 인쇄하는 방식이 일반적이었다. 그러나 이러한 방법은 인쇄 후 잔류용제가 남아서, 환경과 인체에 유해하다는 문제가 있다. In the past, when doing gravure printing on PVC, it was common to melt the PVC with oil-based ink containing a strong solvent, a hazardous chemical. However, this method has the problem that residual solvent remains after printing, which is harmful to the environment and the human body.
따라서, PVC의 그라비아 인쇄에 있어서, 유해화학물질 없이 PVC 원단을 녹이지 않고 인쇄가 되며 접착이 되는 기술이 필요하다. Therefore, in PVC gravure printing, a technology is needed to print and adhere to PVC fabric without melting it and without hazardous chemicals.
한편, 종래 수성 그라비아 잉크를 제안하는 문헌으로는 대한민국 등록특허 제 10-2160953호에 필름용 수성 그라비아 잉크 및 그 제조방법이 개시되어 있다. Meanwhile, as a document suggesting a conventional water-based gravure ink, Korean Patent Registration No. 10-2160953 discloses water-based gravure ink for film and its manufacturing method.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시형태들을 설명한다. 다만, 본 발명의 실시형태는 여러가지 다른 형태로 변형될 수 있으며, 본 발명의 범위가 이하 설명하는 실시형태로 한정되는 것은 아니다. 또한, 본 발명의 실시형태는 당업계에서 평균적인 지식을 가진 자에게 본 발명을 더욱 완전하게 설명하기 위해서 제공되는 것이다. 따라서, 도면에서의 요소들의 형상 및 크기 등은 보다 명확한 설명을 위해 과장될 수 있으며, 도면상의 동일한 부호로 표시되는 요소는 동일한 요소이다.Hereinafter, preferred embodiments of the present invention will be described with reference to the attached drawings. However, the embodiments of the present invention may be modified into various other forms, and the scope of the present invention is not limited to the embodiments described below. Additionally, the embodiments of the present invention are provided to more completely explain the present invention to those with average knowledge in the art. Accordingly, the shapes and sizes of elements in the drawings may be exaggerated for clearer explanation, and elements indicated by the same symbol in the drawings are the same element.
도 1은 본 발명의 실시예에 따른 PVC용 수성 그라비아 잉크의 제조방법을 나타낸 순서도이다.Figure 1 is a flowchart showing a method of manufacturing water-based gravure ink for PVC according to an embodiment of the present invention.
본 발명은 PVC용 수성 그라비아 잉크 및 그의 제조방법에 관한 것으로, 그 제조방법에 있어서는, 배합단계, 분산단계, 혼합단계를 포함하며, 그 잉크는 합성수지, 물, 에탄올, 소포제, 웨팅제, 분산제, 왁스, 안료로 구성된 조성물을 포함하며, 분산수지가 더 포함될 수 있다. The present invention relates to an aqueous gravure ink for PVC and a method for manufacturing the same. The manufacturing method includes a mixing step, a dispersing step, and a mixing step, and the ink includes synthetic resin, water, ethanol, anti-foaming agent, wetting agent, dispersing agent, It includes a composition composed of wax and pigment, and may further include a dispersion resin.
합성수지는 잉크가 원단에 부착이 가능하게 하는 주 물질이며, 수성에폭시, 수성아크릴, 수성우레탄을 포함할 수 있다. 본 발명의 바람직한 실시예에서는 30 내지 40 중량%의 조성비율로 포함하도록 하였다. Synthetic resin is the main material that allows ink to adhere to fabric, and may include water-based poxy, water-based acrylic, and water-based urethane. In a preferred embodiment of the present invention, it is included in a composition ratio of 30 to 40% by weight.
물은 다른 성분들의 용매로 사용되며, 17 내지 46.8 중량%의 범위에서 적절하게 조성비를 조절하여 사용할 수 있다.Water is used as a solvent for other components, and can be used by appropriately adjusting the composition ratio in the range of 17 to 46.8% by weight.
에탄올은 그라비아 잉크의 특성인 속건성을 위해 첨가된다. 상기 에탄올은 잉크에서 용제로 사용되며, 종래의 용제인 톨루엔 등과 달리 유독물질이 아니며 원단에 잔류하지 않고 인쇄과정에서 건조되면서 휘발되는 장점이 있다. 본 발명의 바람직한 실시예에서 상기 에탄올은 10 내지 20 중량%의 조성비율로 포함하도록 하였다. Ethanol is added for quick drying, a characteristic of gravure ink. The ethanol is used as a solvent in ink, and unlike toluene, which is a conventional solvent, it is not a toxic substance and has the advantage of not remaining on the fabric and volatilizing as it dries during the printing process. In a preferred embodiment of the present invention, the ethanol is included in a composition ratio of 10 to 20% by weight.
소포제는 후술할 분산과정에서 물에 의한 기포발생을 막아주어 분산이 원활하게 될 수 있게 한다. 또한, 소포제는 인쇄물에 기포가 나오지 않게 하여 정확하게 인쇄되게 한다. 본 발명의 바람직한 실시예에서 상기 소포제는 0.1 내지 0.5 중량%의 조성비율로 포함하도록 하였다The antifoam agent prevents the generation of bubbles due to water during the dispersion process, which will be described later, and enables smooth dispersion. Additionally, the antifoam agent prevents air bubbles from appearing in the printed matter and ensures accurate printing. In a preferred embodiment of the present invention, the antifoaming agent is included in a composition ratio of 0.1 to 0.5% by weight.
웨팅제는 안료의 재응집을 방지하며 정확한 인쇄를 도와주는 역할을 한다. 본 발명의 바람직한 실시예에서 상기 웨팅제는 0.1 내지 0.5 중량%의 조성비율로 포함하도록 하였다.Wetting agents prevent re-agglomeration of pigments and help with accurate printing. In a preferred embodiment of the present invention, the wetting agent is included in a composition ratio of 0.1 to 0.5% by weight.
분산제는 안료가 분산되도록 하는 것으로 안료의 응집을 방지하고 분산성을 유지시켜주는 역할을 한다. 본 발명의 바람직한 실시예에서 상기 분산제는 2 내지 4 중량%의 조성비율로 포함하도록 하였다.The dispersing agent helps the pigment disperse and prevents the pigment from agglomerating and maintains its dispersibility. In a preferred embodiment of the present invention, the dispersant is included in a composition ratio of 2 to 4% by weight.
