Description
본 발명은 수용성 핫멜트 접착제 조성물에 관한 것으로서, 더욱 상세하게는 폴리(비닐피롤리돈), 폴리(옥시에틸렌)과 그 유도체 등의 기재에 로진 유도체 등의 점착성 부여수지와 왁스 등이 혼합되어 이루어짐으로써, 수용성이면서 접착성 등이 우수하여 종이, 유리, 플라스틱 등 다양한 분야에서 접착제로 유용하게 사용할 수있는 수용성 핫멜트 접착제 조성물에 관한 것이다.The present invention relates to a water-soluble hot melt adhesive composition, and more specifically, to a substrate such as poly (vinylpyrrolidone), poly (oxyethylene), and derivatives thereof, by mixing tackifying resins such as rosin derivatives and waxes, etc. The present invention relates to a water-soluble hot melt adhesive composition which can be usefully used as an adhesive in various fields such as paper, glass, and plastics because it is excellent in water solubility and adhesiveness.
일반적으로 핫멜트 접착제는 지용성으로 물에 풀리거나 녹지 않으며, 열에 의해 융해되어 접착을 이루는 방식의 접착제를 말하며 종이, 유리, 플라스틱, 면, 금속, 비닐 등 다양한 피착제에 열로 녹여 접착시키는 것이다.Generally, hot melt adhesives are fat-soluble and do not dissolve or dissolve in water, and are melted by heat to form an adhesive. The hot melt adhesive is heat-bonded to various adhesives such as paper, glass, plastic, cotton, metal, and vinyl.

본 발명은 일반 핫멜트 접착제와 같은 방법으로 사용하기 때문에 용매를 사용치 않아 작업환경이 개선되고 수용화되기 때문에 재활용이 가능할 뿐아니라 접착력도 우수한 수용성 핫멜트 접착제 조성물을 제공하는데 그 목적이 있다.The present invention is intended to provide a water-soluble hot melt adhesive composition that can be recycled as well as excellent adhesive strength because the working environment is improved and accepted because no solvent is used because it is used in the same way as a general hot melt adhesive.
이하, 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.
본 발명은 수용성 핫멜트 접착제 조성물에 있어서, 분자량 3,000 ~ 100,000의 폴리(비닐피롤리돈), 분자량 50,000 ~ 200,000의 폴리(옥시에틸렌), 분자량 1,000 ~ 100,000의 폴리(비닐알콜) 및 아크릴산 함량이 5 ~ 50%이고 용융점도지수가 0.5 ~ 3,000인 폴리(에틸렌 아크릴산) 중에서 선택된 1 내지 2종 이상의 것 5 ~ 60 중량%와 점착성 부여수지 5 ~ 50 중량% 및 왁스 또는 가소제 5 ~ 50 중량%로 이루어진 것을 그 특징으로 한다.The present invention is a water-soluble hot melt adhesive composition, poly (vinylpyrrolidone) having a molecular weight of 3,000 to 100,000, poly (oxyethylene) having a molecular weight of 50,000 to 200,000, poly (vinyl alcohol) having a molecular weight of 1,000 to 100,000 and acrylic acid content of 5 ~ 1 to 2 or more selected from poly (ethylene acrylic acid) having a melt viscosity index of 50 to 50% and a melt viscosity index of 5 to 60% by weight, 5 to 50% by weight of a tackifying resin, and 5 to 50% by weight of a wax or a plasticizer. It is characterized by.
이와같은 본 발명을 더욱 상세히 설명하면 다음과 같다.Referring to the present invention in more detail as follows.
본 발명은 폴리(비닐피롤리돈) 등의 기재와 점착성 부여수지 및 왁스 또는 가소제 등으로 이루어짐으로써 재활용이 가능하고 접착력이 우수한 수용성 핫멜트 접착제 조성물에 관한 것으로서, 본 발명에서 사용되는 기재는 상기한 바와 같은데 그 사용량이 5 중량% 미만이며 수용화 되지 않는 문제가 있고, 60 중량%를 초과하면 작업성 및 가공성에 문제가 있어 바람직하지 않다.The present invention relates to a water-soluble hot melt adhesive composition which is recyclable and excellent in adhesive strength, comprising a substrate such as poly (vinylpyrrolidone), a tackifying resin, a wax or a plasticizer, and the like. It seems that the amount of use is less than 5% by weight and there is a problem that it is not acceptable, and if it exceeds 60% by weight, there is a problem in workability and processability is not preferable.
또한, 기재로 사용되는 폴리(비닐피롤리돈), 폴리(옥시에틸렌), 폴리(비닐알콜)의 분자량이 상기 범위를 벗어나면 물에 녹지 않는 문제가 있어 바람직하지 않고, 폴리(에틸렌 비닐아세테이트)의 비닐 아세테이트 함량이 5 ~ 50%를 벗어나면 상용성에 문제가 있으며 용융점도지수가 0.5 ~ 3,000을 벗어나면 흐름성에 문제가 있어 좋지 않다.In addition, if the molecular weight of the poly (vinylpyrrolidone), poly (oxyethylene), poly (vinyl alcohol) used as the substrate is out of the above range there is a problem that it does not dissolve in water, which is not preferable, poly (ethylene vinyl acetate) If the vinyl acetate content of 5 ~ 50% is out of compatibility problem, melt viscosity index is out of 0.5 ~ 3,000 is not good flow problem.
또한, 폴리(에틸렌 아크릴산)의 아크릴산 함량이 5 ~ 50%를 벗어나면 사용성에 문제가 있고, 용융점도의 지수가 0.5 ~ 3,000을 벗어나면 흐름성에 문제가 있어 본 발명에 적합치 않게 된다. 이와같이, 본발명에서 사용되는 폴리(비닐피롤리돈) 등의 기재성분은 수용성이 뛰어나 그 외에 첨가되는 물에 녹지않는 지용성 성분과 함께 접착제를 구성하여 사용하는 경우 그 접착제 부분을 물에 담그게 되면 접착제에 혼합되어 있는 폴리(비닐피롤리돈) 등의 수용성 기재성분이 물에 녹게되며, 이 때 물에 녹지아니하는 다른 성분들도 함께 물에 분산되기 때문에 접착제로서의 성질은 완전히 사라지고 외관상 물에 녹는 것과 같은 효과를 나타내는데 이런 이유로 본 발명의 접착제는 수용성을 나타내는 것이다.In addition, when the acrylic acid content of the poly (ethylene acrylic acid) is out of 5 to 50%, there is a problem in usability, and if the melt viscosity index is out of 0.5 to 3,000, there is a problem in flowability, which is not suitable for the present invention. As described above, when the base component such as poly (vinylpyrrolidone) used in the present invention is composed of an adhesive with a fat-soluble component which is excellent in water solubility and insoluble in water added thereto, the adhesive portion is immersed in water. The water-soluble base component such as poly (vinylpyrrolidone) mixed in the adhesive is dissolved in water. At this time, other components which are insoluble in water are also dispersed in the water, so the properties of the adhesive disappear completely and are soluble in water. The adhesive of the present invention exhibits water solubility.

[실험예]Experimental Example
상기 실시예 1 ~ 7, 비교예 1 ~ 4에서 제조된 접착제의 접착력 및 수용해 시험을 다음과 같은 방법으로 실시하였다.The adhesion and water solubility test of the adhesive prepared in Examples 1 to 7, Comparative Examples 1 to 4 were carried out in the following manner.
박리 접착강도 시험을 위한 시험편으로는 부직포, 종이, PE 필름, 알루미늄, 유릴르 이용하였고, 수용해 시험을 위해서는 알루미늄 판을 이용하였다.Nonwoven fabric, paper, PE film, aluminum, and uril were used as test pieces for the peel adhesion strength test, and an aluminum plate was used for the water solubility test.
시험편은 표면을 깨끗이 한 후 60℃의 오븐에서 30분간 건조하였다. 접착제를 160℃의 온도를 용융하여 피착제의 표면에 도포하고 무게 약 1,000g의 압착기구를 이용하여 약 2분간 압착하여 접착시킨다. 이때 동일 시험편을 5개를 사용하였으며, 시험기는 스위스 쯔빅사의 만능 인장시험기 1435기종을 사용하였다. 박리접착강도 측정시의 인장속도는 170±17㎜/min이었다. 수용해성 시험은 알루미늄 판을 톨루엔으로 잘 세척한 후 60℃ 오븐에서 약 1시간동안 건조 후 사용하였으며, 알루미늄 판에 접착제를 영국 프린팅(R.K.Printing)사의 모델 KCC 101코팅기를 이용하여 약 100μ±10μ으로 코팅하여 시험편을 만들고, 물 용해시험은 pH6의 물과 pH7 ~ 12의 알칼리물, pH5 ~ 1의 물을 준비하여 0℃에서부터 80℃가지의 온도범위에서 실험하였다. 각 온도 및 각 pH에서의 시험횟수는 3회로 하였다.The test piece was cleaned for 30 minutes and then dried in an oven at 60 ° C. The adhesive is melted at a temperature of 160 ° C. and applied to the surface of the adherend, followed by pressing for about 2 minutes using a pressing apparatus weighing about 1,000 g. In this case, five identical test pieces were used, and a tester used a universal tension tester 1435 model of Zwick, Switzerland. The tensile velocity at the time of peel adhesion strength measurement was 170 +/- 17 mm / min. The water solubility test was used after washing the aluminum plate well with toluene and drying it in an oven at 60 ° C. for about 1 hour, and using the model KCC 101 coating machine of RKPrinting Co., Ltd. The test piece was prepared by coating, and the water dissolution test was performed at a temperature range of 0 ° C. to 80 ° C. by preparing water of pH 6, alkaline water of pH 7 to 12, and water of pH 5 to 1. The test frequency at each temperature and pH was three times.
이상고 같은 방법으로 실시하여 접착 박리강도는 다음 표 1에, 물의 온도 및 pH에 따른 접착제의 용해속도 측정결과를 각각 다음 표 2와 3에 나타내었다.In the same manner as described above, the adhesive peel strength is shown in Table 1, and the results of measuring the dissolution rate of the adhesive according to the temperature and pH of the water are shown in Tables 2 and 3, respectively.
