Description

수용성 점착층 형성용 조성물을 포함하는 점착 테이프Adhesive tape containing a composition for forming a water-soluble adhesive layer
본 발명은 수용성 점착층 형성용 조성물을 포함하는 점착 테이프에 관한 것으로, 상세하게는 산업용 점착 테이프에 적용되는 점착층으로 수용성 점착층을 적용하기 위한 수용성 점착층 형성용 조성물에 관한 것이다.The present invention relates to an adhesive tape containing a composition for forming a water-soluble adhesive layer, and more specifically, to a composition for forming a water-soluble adhesive layer for applying a water-soluble adhesive layer as an adhesive layer applied to an industrial adhesive tape.
일반적으로 전자부품의 생산에 사용되는 산업용(제지 공장에서 제지의 가공 작업시) 혹은 포장물의 포장용 접착용 테이프가 널리 사용되고 있다.In general, adhesive tapes are widely used for industrial purposes (during paper processing in paper mills) used in the production of electronic components or for packaging packaging materials.
이와 같은 분야에서 OPP 점착 테이프 혹은 종이의 표면에 PE 수지 필름을 접합시켜서 제조된 점착 테이프를 사용하는 것은 주지된 사실이다.It is a well-known fact that in such fields, OPP adhesive tapes or adhesive tapes manufactured by bonding a PE resin film to the surface of paper are used.
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 existing OPP adhesive tapes, but also adhesive tapes made by bonding a PE resin film to the surface of paper are 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.
이러한 불편함을 해소하기 위해 물에 녹는 수해리성 필름이나 접착제가 개발되고 있다.To solve this inconvenience, water-soluble films or adhesives that dissolve in water are being developed.
그러나 분산액에 의한 접착제는 폴리우레탄 수지의 입자 직경이 작기는 하지만 실질적으로 계면활성제를 첨가하지 않아 표면장력이 크며, 접착제 도포시의 전연성, 다공성 기재에 대한 침투성, 접착강도 등의 성능을 충분히 만족시키지 못하고, 접착제가 물에서 완전 해리되지 않고 잔여물이 남아 이를 처리하는 후공정이 요구되는 문제점이 있다.However, although the dispersion adhesive has a small particle diameter of polyurethane resin, the surface tension is large because no surfactant is added, and it does not sufficiently satisfy performance such as malleability when applying the adhesive, penetration into porous substrates, and adhesive strength. However, there is a problem in that the adhesive does not completely dissociate in water and a residue remains, requiring a post-process to dispose of it.
이에, 물 속에서 완전 해리되어 잔류물이 전혀 없는 친환경 접착 조성물에 대한 연구 개발이 필요성이 대두되고 있다. 더불어, 접착력과 유지시간을 향상시킬 수 있는 소재에 대한 개발이 필요하다.Accordingly, the need for research and development of an eco-friendly adhesive composition that completely dissociates in water and leaves no residue is emerging. In addition, there is a need to develop materials that can improve adhesion and retention time.
