본 발명은 재활용이 가능한 친환경 종이테이프에 관한 것으로서, 종이재질의 원지 일면에 점착제용 조성물이 도포된 점착층을 가지는 종이테이프로서, 상기 점착제용 조성물이 불포화성 에스텔 축합물을 이용한 다기능성 아크릴 공중합체로 이루어지고, 상기 점착층이 알칼리수에 의해 해리되는 것을 특징으로 하는 본 발명에 따른 친환경 알칼리수 해리성 점착제를 갖는 종이테이프는 알칼리성 용제에 잘 해리되는 점착제용 조성물을 종이테이프 원지의 일면에 도포하여 점착제로 사용함으로써, 포장용 종이박스를 재활용하고자 할 때, 알칼리 용액을 통해 상기 점착제용 조성물을 해리시킬 수 있어, 종이테이프를 일일이 종이박스에서 제거해야하는 번거로움 없이 부착된 상태로 재활용처리가 가능하여 경제성 및 환경 보호 효과를 수득할 수 있을 것으로 기대된다.

Description
본 발명은 재활용이 가능한 친환경 종이테이프에 관한 것으로서, 더욱 상세하게는 알칼리수에 해리(解離)되는 점착제용 조성물이 일면에 도포되는 친환경 알칼리수 해리성 점착제를 갖는 재활용이 가능한 친환경 종이테이프에 관한 것이다.The present invention relates to a recyclable, eco-friendly paper tape, and more specifically, to a recyclable, eco-friendly paper tape having an eco-friendly alkaline water-dissociable adhesive coated on one side with an adhesive composition that dissociates in alkaline water.
종이테이프는 피부착물에 달라 붙은 상태를 유지하도록 그 용도와 사용방법에 따라 적절한 접착력을 갖도록 그 기재의 일면에 점착제를 도포시켜서 물건의 밀봉상태를 유지시키거나 서로 이격되어 있는 물건들을 분리되지 않도록 접착된 상태로 유지하게 하는 것이다.Paper tape is used to maintain the seal of an object by applying an adhesive to one side of the substrate to have appropriate adhesive strength depending on the purpose and method of use so that it remains attached to the skin or to prevent objects separated from each other from separating. It is to keep it in its current state.
일반적으로 포장용 종이테이프는 크래프트지를 기초재로 하여 일측 면에 점착제층을 형성하고, 타측면에 폴리에틸렌층을 형성하며 상기 폴리에틸렌층위에 실리콘계 박리제층을 형성하여 구성된다.In general, packaging paper tape is made of kraft paper as a base material, forming an adhesive layer on one side, forming a polyethylene layer on the other side, and forming a silicone-based release agent layer on the polyethylene layer.
일반적으로 산업용(제지 공장에서 제지의 가공 작업시) 혹은 포장물의 포장용을 접착용 테이프 즉, OPP 점착 테이프 혹은 종이의 표면에 PE 수지 필름을 접합 시켜된 점착 테이프를 사용함은 주지된 사실이다.It is a well-known fact that adhesive tape, that is, OPP adhesive tape or adhesive tape made by bonding a PE resin film to the surface of paper, is generally used for industrial purposes (during paper processing at a paper mill) or for packaging packages.
그러나, 기존의 OPP 점착 테이프는 물론 종이의 표면에 PE 수지 필름을 접합시켜 만든 점착 테이프 역시 그 수지필름의 표면에 유성 점착제를 도포하여 제조하고 있다.However, not only the existing OPP adhesive tape, but also the adhesive tape made by bonding a PE resin film to the surface of paper is manufactured by applying an oil-based adhesive to the surface of the resin film.
이 때문에 종이 포장물을 포장하는 포장용으로 사용하는 경우에는, 종이 포장물을 재활용하고자 할 시, 상시 비닐 테이프를 사람들이 일일이 제거하지 않으면 안되는 번거로움과 불편이 있고, 설령 별도 분리 처리를 한다고 하더라도 그 처리 비용이 많이 소요되는 단점이 있으며, 특히 폐기물로 별도 분리 후 소각 처리시에는 소각 과정에서 '다이옥신'이라고 하는 유독 가스가 배출되어 대기를 오염시키는 문제를 일으킴과 아울러 자원의 낭비를 초래하는 문제점이 있다.For this reason, when paper packaging is used for packaging, there is the inconvenience and inconvenience of having to remove the vinyl tape one by one at all times when recycling the paper packaging, and even if it is separated separately, the processing cost is high. This has the disadvantage of requiring a lot of waste, and in particular, when it is separated into waste and then incinerated, toxic gas called 'dioxin' is emitted during the incineration process, causing air pollution and a waste of resources.
작금의 환경문제는 국가간의 통상분쟁이 야기될 만큼 심각한 처지에 놓여있는 것으로서 산업화의 진행과정을 통해 무분별하게 생산된 많은 산물이 사용중이나 혹은 사용후의 폐처리과정에서 자연 생태계를 위협하는 등 여러 부작용을 유발하고 있음으로 그 개선책의 마련이 범세계적으로 잇슈화되고 있는 실정이다.Current environmental problems are serious enough to cause trade disputes between countries. Many products produced indiscriminately through the process of industrialization have various side effects, such as threatening the natural ecosystem during use or during the waste disposal process after use. As a result, the development of improvement measures is becoming a global issue.
전통적인 의미에서의 환경보존행위는 수거된 폐기물의 자연분해 시간을 단축시키거나 혹은 유해물질발생을 억제하기 위한 보완책을 마련하는 등 다소 소극적인 행위에 한정되었으나 최근들어 부족자원의 효율적 재활용을 도모하기 위한 일환으로 친환경적 재활용을 적극적으로 모색하게 되었다.In the traditional sense, environmental preservation activities were limited to somewhat passive actions such as shortening the natural decomposition time of collected waste or preparing supplementary measures to suppress the generation of hazardous substances, but recently, it has been used as an effort to promote efficient recycling of scarce resources. This led to an active search for eco-friendly recycling.
특히, 합성수지 혹은 폴리에틸렌이 코팅된 박리지가 일반 재생지에 혼재되어 폐기될 경우 그 재생처리가 매우 곤란하였고, 이와 함께 분리 처리되어야 할 종이테이프의 점착제가 대게의 경우 아크릴 혹은 고무 등이 유성계 또는 합성수지의 에멀젼계 형태로 사용되고 있어 내한성, 봉함유지력 및 보존성(경시변화)이 좋지 않고, 리펄핑시 에멀젼의 입자부유물이 표면에 다시 응집되어 2차 제거가 필요하다는 이유 등을 포함하고 있어 그 처리가 결코 용이하지 못함으로 종래 종이테이프의 재활용에 대한 방안은 제혀 제시되어 있지 못하였다.In particular, when synthetic resin or polyethylene-coated release paper was mixed with general recycled paper and disposed of, recycling was very difficult, and the adhesive of the paper tape that had to be separated along with it was usually made of oil-based or synthetic resin such as acrylic or rubber. Since it is used in the form of an emulsion, it has poor cold resistance, sealing ability, and preservation (change over time), and when repulping, suspended particles in the emulsion coagulate again on the surface, necessitating secondary removal, so it is not easy to process. As a result, no plan for recycling conventional paper tapes has been proposed.
이에 본 발명에서는 상기한 문제점을 해결하기 위해 계속 연구를 진행하던 중 알칼리성 용제에 잘 해리되는 점착제용 조성물을 종이테이프 원지의 일면에 도포하여 점착제로 사용되어, 포장용 종이박스를 재활용하고자 할 때, 종이테이프를 일일이 제거하지 않고 부착된 상태로 재활용처리가 가능하게 하여, 경제성 및 환경 보호 효과를 크게 얻을 수 있는 친환경 알칼리수 해리성 점착제를 갖는 종이테이프를 제공함에 그 목적이 있다.Accordingly, in the present invention, while continuing research to solve the above problems, an adhesive composition that easily dissociates in alkaline solvents was applied to one side of the paper tape base paper and used as an adhesive, so that when recycling paper boxes for packaging, the paper was used as an adhesive. The purpose is to provide a paper tape with an eco-friendly alkaline water dissociable adhesive that can be recycled in its attached state without having to remove the tape one by one, thereby achieving significant economic and environmental protection effects.
따라서, 본 발명에서 해결하고자 하는 기술적 과제는 상술한 문제점을 해결하기 위한 것으로서, 포장용 종이박스를 재활용하고자 할 때 종이테이프를 일일이 제거하지 않고 부착된 상태로 재활용 처리가 가능하여 경제성 및 환경 보호 효과를 수득할 수 있는 친환경적인 종이테이프를 제공하기 위한 것이다.Therefore, the technical problem to be solved by the present invention is to solve the above-mentioned problem. When recycling a paper packaging box, it is possible to recycle the paper tape in an attached state without removing it one by one, thereby improving economic efficiency and environmental protection. The purpose is to provide an eco-friendly paper tape that can be obtained.
