수용성 접착제의 제조방법{Method for manufacturing a water-soluble adhesive}Method for manufacturing a water-soluble adhesive

본 발명은 수용성 접착제의 제조방법에 관한 것으로서, 보다 상세하게는 폐 피착제의 재활용성을 높이고, 유기용매를 사용하지 않음으로써 환경 친화적인 수용성 접착제의 제조방법에 관한 것이다.The present invention relates to a method for producing a water-soluble adhesive, and more particularly, to a method for producing an environmentally friendly water-soluble adhesive by improving the recyclability of waste adhesive and not using an organic solvent.

일반적으로, 접착제는 금속, 비금속 및 기타의 접착에 사용되는 물질로, 동물성과 식물성 및 합성수지로 분류된다. 동물성 접착제로는 우유 속 단백질인 카세인과 동물의 간장이나 근육 등에 함유되어 있는 글리코겐 등이 있으며, 식물성 접착제는 옻, 풀 등이 있다. 그리고, 공업 접착제의 주를 이루는 합성수지로 된 에폭시 수지 및 페놀 수지가 있다.In general, adhesives are materials used for bonding metals, nonmetals and other, and are classified into animal, vegetable and synthetic resins. Animal adhesives include casein, which is a protein in milk, and glycogen, which is contained in the liver, muscle, etc. of animals, and vegetable adhesives include lacquer, grass, and the like. In addition, there are epoxy resins and phenol resins made of synthetic resins which are mainly used for industrial adhesives.

비수용성 접착제는 유기용매를 사용하는 접착제로써, 유기용매를 사용한 비수용성 접착제는 수용성 접착제에 비해 접착력이 우수하나, 포장지를 재생하여 사용할 시 접착제의 제거가 어렵다. 비수용성 접착제를 사용한 포장지 등을 재생하여 제작된 용기는 접착제가 완전히 제거되지 않아 접착제 및 불순물이 함유되어 재생 용기의 질이 저하된다.The non-aqueous adhesive is an adhesive using an organic solvent. The non-aqueous adhesive using an organic solvent has better adhesive strength than a water-soluble adhesive, but it is difficult to remove the adhesive when regenerating packaging. Containers made by regenerating wrapping paper or the like using a water-insoluble adhesive are not completely removed from the adhesive, so that the quality of the regeneration container is degraded because the adhesive and impurities are contained.

또한, 접착제를 제조하는 과정에서 유기용매를 사용하기 때문에 유독성 가스및 화재가 발생될 우려가 있고, 제조과정에서 악취가 발생하는 등 작업 환경 및 작업 위생이 열악한 실정이다.In addition, since an organic solvent is used in the manufacture of the adhesive, toxic gases and fires may be generated, and odor is generated in the manufacturing process.

이와 같은 유기용매를 사용하는 접착제의 단점으로 인하여 환경적, 작업 위생적, 작업 안정적인 측면에서 우수한 물을 바탕으로 하는 수용성 접착제의 개발이 요구되어 진다.Due to the disadvantage of the adhesive using the organic solvent, it is required to develop a water-soluble adhesive based on excellent water in terms of environmental, work hygiene, work stability.

이러한 요구에 부응하여 개발된 수용성 접착제는 물을 용매로 하기 때문에 물의 높은 증발 엔탈피로 인하여 접착부위가 굳어지는데 소요되는 시간이 길어진다. 즉, 접착 부위에서 물의 증발 속도가 유기용매에 비해 느리기 때문에 접착시간이 길다는 단점이 있었다. 또한, 친수성을 띠는 이온성 또는 비이온성 계면 활성제 및 이온성 첨가물, 수용성 폴리머 등으로 구성되어 접착 부위의 내수성이 약하여 접착력이 떨어지는 단점이 있었다.Since the water-soluble adhesive developed in response to this demand uses water as a solvent, the time required to harden the adhesive site is increased due to the high evaporation enthalpy of water. That is, the adhesion time is long because the evaporation rate of water at the bonding site is slower than the organic solvent. In addition, hydrophilic ionic or nonionic surfactants and ionic additives, water-soluble polymers, etc. have a disadvantage in that the adhesion strength is poor because the water resistance of the bonding site is weak.

이러한 단점을 보완하기 위하여 우레아-포름알데히드, 멜라민-포름알데히드, 리소신올-포름알데히드 등의 수지를 첨가하기도 하지만 그 효과가 그리 크지는 않았다. 그리고, 종래의 수용성 접착제의 경우 습한 환경에서 장기간 방치할 경우 접착부위에서 곰팡이 및 미생물의 번식이 발생하여 접착 강도의 약화 및 냄새가 발생하는 등의 문제점이 있다.In order to compensate for these disadvantages, resins such as urea-formaldehyde, melamine-formaldehyde, and lysosinol-formaldehyde may be added, but the effect was not so great. In the case of a conventional water-soluble adhesive, when left in a humid environment for a long time, mold and microorganisms grow at the adhesive site, and thus there is a problem such as weakening of adhesive strength and odor.

본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 발명된 것으로, 수용성 접착제에 유기용매 대신 수용성 셀룰로오스를 사용하여 빠른 접착 강도를 갖으며, 접착력이 우수하고 미생물에 대한 항균성을 보강함으로써, 유기용매를 사용한 접착제의 각종 단점을 극복하고, 접착제를 사용한 포장지 등을 재생할 때 접착제가 완전하게 제거되어 환경 친화적인 수용성 접착제의 제조방법을 제공하는데 그 목적이 있다.The present invention has been invented to solve the above conventional problems, by using a water-soluble cellulose instead of an organic solvent in a water-soluble adhesive, has a fast adhesive strength, excellent adhesion and antimicrobial resistance to microorganisms, It is an object of the present invention to overcome various disadvantages of the used adhesive and to completely remove the adhesive when regenerating a wrapping paper using the adhesive to provide an environmentally friendly water-soluble adhesive.
