본 고안은 카드용지와 같은 빛통과 차단기능을 갖는 재활용 접합지에 관한 것으로 더욱 구체적으로는 양측면이 원지로 적층되고 원지와 원지사이에 완벽한 빛통과 차단기능을 갖는 인쇄층과 접합지 전체에 탄성기능을 부여하는 카드용지와 같은 빛통과 차단기능을 갖는 접합지의 구성에 관한 기술분야라 하겠다.The present invention relates to a recycled bonding paper having a light blocking function such as a card paper. More specifically, both sides of the paper are laminated on the paper and the elastic layer is applied to the entire printing layer and the bonding paper having a perfect light passing function between the paper and the paper. It is a technical field related to the construction of a bonding paper having a light passage blocking function such as a card paper to be given.

종래의 카드용지와 같은 접합지는 원지와 원지 사이에 비수용성의 접착제에 카본 분말을 첨가 인쇄층을 형성하여 일체화시키므로서 빛통과 차단기능을 부여한 접합지(카드용지)가 대부분이다.Bonding papers, such as conventional card papers, are mostly bonded papers (card papers) provided with light-blocking functions by forming a print layer by adding carbon powder to a non-aqueous adhesive between paper and paper.

이와 같은 접합지는 폐지 해리시 접착성의 잉크가 물에 쉽게 팽윤되지 않고 녹지않아 폐지의 펄프화에 큰 곤란을 겪고 있으며, 표면인쇄시 잉크제트 방식에는 문제가 없지만 토너 방식에서는 토너를 고착건조시키는 과정에서 200℃ 이상의 고열이 가해지므로 잉크접착층이 열화되기 쉽고 기포가 발생하여 접착성이 떨어져 접합지의 장기간 사용시 원지층이 분리되는 현상이 발생한다.Such bonding paper suffers a great difficulty in pulp of waste paper because adhesive ink does not swell easily in water and does not melt upon dissociation of waste paper, and there is no problem in ink jet method during surface printing, but in the process of fixing toner by toner method Since a high temperature of 200 ° C. or more is applied, the ink adhesive layer is easily deteriorated, bubbles are generated, and adhesiveness is poor, resulting in a phenomenon that the base layer is separated when the bonding paper is used for a long time.

카드용지와 같이 양측의 원지 사이에 완벽한 빛통과 차단기능을 갖는 접착층을 형성하여 접합지를 구성함에 있어서 완벽한 빛통과 차단기능을 기본 목적을 충분히 달성시키고 접합지의 표면 인쇄시에 고열로 발생하는 문제점의 해소는 물론 카드용지와 같은 접합지에서 필수적으로 요구되는 내굴곡성과 탄성기능이 충분히 부여되며 더욱이 재활용까지도 가능한 완벽하게 빛통과를 차단하기 위한 재활용 접합지를 제공함에 목적이 있다 하겠다.The perfect light passage blocking function can be achieved in forming the bonding paper by forming the adhesive layer with perfect light passage and blocking function between the papers on both sides like card paper, and solve the problem of high temperature when printing the surface of the bonding paper. Of course, the purpose is to provide a recycled bonding paper to completely block the light passing through the endowed with sufficient flex resistance and elasticity required in the bonding paper such as card paper, and even recycled.

도 1 - 본 고안의 측단면도1-Side cross-sectional view of the present invention

본 고안에 의한 빛통과 차단기능을 갖는 접합지의 구성은 도 1에서와 같이 상층의 원지(1)의 이면에 폴리우레탄접착층(2)이 형성되고 폴리우레탄수지계접착층(2)과 인쇄층(3)이 접하며 이 인쇄층(3)이 원지(1') 이면에 인쇄된 적층구조의 접합지라 할 수 있다.The constitution of the bonding paper having a light passage blocking function according to the present invention is a polyurethane adhesive layer (2) is formed on the back surface of the base paper 1 of the upper layer, as shown in Figure 1, the polyurethane resin adhesive layer (2) and the printing layer (3) It can be said that this printing layer 3 is in contact with the laminated structure printed on the back surface of the base paper 1 '.

본 고안에서 원지(1)(1')는 물론 내첨사이징 및 표면 사이징이된 원지로서 특히 원지의 조직은 탄성을 갖는 내첨사이징이 첨가되고 표면층은 인쇄성이 좋도록 표면 사이징된 원지임은 물론이다.In the present invention, the base paper (1) (1 '), as well as the base paper with internal sizing and surface sizing, in particular, the tissue of the base paper is added with an elastic internal sizing with elasticity and the surface layer is a surface sized base paper for good printability. .

접착층은 카드용지에서 요구되는 탄성을 갖도록 탄성이 우수한 폴리우레탄을 사용하고 또한 본 고안에 의한 접합지의 재활용을 위해서 수용성의 폴리우레탄을 사용하므로서 폐접합지를 재활용하는 경우에 있어서 해리시에 물에 쉽게 팽윤 용해되어 쉽게 재활용할 수 있다.The adhesive layer is easily swelled in water during dissociation when recycling waste bonded papers by using polyurethane having excellent elasticity to have elasticity required for card paper and water-soluble polyurethane for recycling the bonded paper according to the present invention. It can dissolve and be easily recycled.

또한 접합지(카드용지) 표면에 인쇄는 주로 잉크젯 방식과 토너 방식으로 인쇄하게 되는데 잉크젯 인쇄방식에는 큰 문제점이 없지만 토너인쇄 방식에서는 토너를 고착 건조시키는 과정에서 200℃ 이상의 고열이 발생하게 된다.In addition, the printing on the surface of the bonding paper (card paper) is mainly performed by the inkjet method and the toner method, but there is no big problem in the inkjet printing method, but in the toner printing method, high heat of 200 ° C. or more occurs in the process of fixing and drying the toner.

이 과정에서 일반적인 접착제는 기포가 발생하거나 접착층이 열화될 수 있고 에멀젼이 경화되므로서 접착기능이 약화되어 층간에 분리현상이 발생하기 쉽다.In this process, general adhesives may generate bubbles or deteriorate the adhesive layer, and as the emulsion is cured, the adhesive function is weakened, so that separation between layers is likely to occur.

이와 같은 문제로 내열성이 높은 폴리아마이드계 접착성 잉크에 카본 분말에 첨가시킨 잉크로 인쇄층을 형성하므로서 고열로 발생하는 문제점을 해결할 수 있다.This problem can solve the problem of high heat by forming the printing layer with the ink added to the carbon powder in the polyamide adhesive ink having high heat resistance.

본 고안에서 잉크층을 형성하는 폴리아마이드계수지(nylon 66)은 용융점이 264℃로서 토너인쇄 과정에서 발생하는 고열에 충분히 견딜 수 있고 접착성도 그대로 유지할 수 있으며, 폐접합지(카드용지) 등의 재활용시 개미산(Formic Acid)수용액에 쉽게 용해되어 재활용할 수 있으며, 또한 나이론을 공축합한 수지를 접착성의 잉크를 사용할 경우에는 메타놀에 잘 용해되므로서 쉽게 인쇄가 가능하며 재활용시에도 메타놀수용액에 쉽게 용해되므로서 재활용이 용이하다.In the present invention, the polyamide resin (nylon 66) forming the ink layer has a melting point of 264 ° C., which can sufficiently withstand the high heat generated during the toner printing process and maintain the adhesiveness. When recycled, it is easily dissolved in formic acid aqueous solution and can be recycled.In addition, when the adhesive ink is used, the co-condensed resin of nylon is easily dissolved in methanol, and can be easily printed. It is easy to recycle because it is dissolved.

본 고안에 의한 빛통과 차단기능을 갖는 재활용 접합지(카드용지)는 빛통과 차단기능이 완벽할 뿐 아니라 양측 원지접합을 위에서 사용되는 우레탄계 접착층으로 극히 우수한 탄성을 가지므로 내굴곡성이 우수하고 차단기능을 위해서 사용되는 나이론 수지계의 접착성 잉크를 사용하므로서 인쇄층의 내열성이 뛰어나 기포발생이나 접착제의 열화에 의한 접착기능을 그대로 유지할 수 있을 뿐만 아니라 이 또한 높은 탄성을 갖고 있어 카드용지에서 요구되는 특성을 충족시킬 수 있는 빛통과 차단기능을 갖는 재활용 접합지(카드용지)를 얻을 수 있다.Recycled laminated paper (card paper) with light passage blocking function according to the present invention is not only perfect for light passage blocking function but also has excellent elasticity as it has an excellent elasticity as a urethane-based adhesive layer used on both sides of the base bonding above. By using the nylon resin adhesive ink used for the excellent heat resistance of the printing layer, not only can it maintain the adhesive function due to bubble generation or the adhesive deterioration, but also has high elasticity, so it can be used for card paper. Recyclable bonding paper (card paper) can be obtained which can meet the light-passing function.
