Description
본 발명은 열가소성 엘라스토머 조성물에 관한 것으로서, 상세하게는 열융착 필름에 사용할 수 있는 열가소성 엘라스토머 조성물에 관한 것이다.TECHNICAL FIELD [0001] The present invention relates to a thermoplastic elastomer composition, and more particularly to a thermoplastic elastomer composition usable for a heat-sealable film.
열 용융형 접착제는 열가소성 특성을 갖는 접착제이다. 이들 접착제는 고온에서 유동적이고, 저온에서 고체이다. 열 용융형 접착제의 주요 이점은 캐리어 유체가 없기 때문에 접착제가 기판에 적용된 후 이를 건조시킬 필요가 없다는 것이다. 따라서, 용매 사용과 연관된 위험성이 해소되고, 보다 신속한 공정이 이루어지며, 저비용의 효과를 도모할 수 있다. The heat-melt type adhesive is an adhesive having thermoplastic properties. These adhesives are fluid at high temperatures and solid at low temperatures. The main advantage of the hot melt adhesive is that it does not need to be dried after the adhesive has been applied to the substrate since there is no carrier fluid. Accordingly, the risk associated with the use of the solvent is solved, a faster process is performed, and a low-cost effect can be achieved.
열 용융형 접착제에 사용되는 열가소성 수지에는 많은 종류가 있으나, 대표적으로 열용융(hot-melt)용 염화비닐수지(PVC, Poly vinyl chloride)가 있다. 열용융용 염화비닐수지는 가열 용융한 후 냉각에 의해 경화되어 접착력을 발휘하므로 접착시간이 빠르고, 무용제형이므로 건조단계에서 안정성이 뛰어나다. 또한, 접착 후 수시간 내지 수일 후에 고상화 단계를 거쳐 내수성 및 기계적 강도를 갖게 된다.There are many kinds of thermoplastic resins used in hot melt adhesives, but typically there are vinyl chloride resins for hot-melt (PVC). Since the vinyl chloride resin for heat melting is hardened by heating and then hardened by cooling to exhibit an adhesive force, the adhesive time is fast, and since it is a solvent-free form, it is excellent in stability in the drying step. Further, after several hours to several days after the bonding, the resin is solidified and has water resistance and mechanical strength.
특히, 열 용융 접착시에는 점착성(tacky)을 가지나, 접착 후 고형화 단계를 거치면 비점착성(tack-free)을 가지기 때문에 필름 형태의 접착제를 제조할 수 있다. 따라서, 접착층의 외부로의 노출이 불가피한 적층체에도 적용될 수 있다.Particularly, when a hot melt adhesive is used, it has a tacky property. However, since it has a tack-free property after the solidification step after bonding, a film type adhesive can be produced. Therefore, the present invention can be applied to a laminate in which exposure of the adhesive layer to the outside is inevitable.
그러나, 종래의 열용융용 염화비닐수지는 염소(Cl)를 함유하고 있어 환경문제를 야기하는 문제점이 있다. 특히 PVC 소재의 사용에 대한 규제가 본격화되는 시점이 조만간 도래할 것으로 예상되고 있으며 VCM 강판 분야에서 PVC 필름을 대체할 만한 소재의 개발이 미흡하여 전방산업인 가전제품의 수출에 막대한 지장을 초래할 것으로 예상된다. PCM 강판으로는 VCM 강판의 고급스러운 디자인 및 고선영성, 투명성을 확보하기 어렵기 때문에 PVC 필름을 대체하는 PVC free Hotmelt 필름의 개발이 시급한 상황이다. 또한 기존의 필름 접착공정에는 다량의 접착제가 사용되며 접착제에는 휘발성유기화합물(VOC)을 다량(수십% 이상) 함유하고 있어 접착공정 중에 다량의 VOC가 방출되는 문제점이 있다. However, the conventional vinyl chloride resin for thermal melting contains chlorine (Cl), which causes environmental problems. In particular, PVC materials are expected to come into full swing in the near future, and it is anticipated that PVC materials will not be developed as substitutes for VCM in the field of VCM. do. As it is difficult to secure the high-grade design, high-linearity and transparency of VCM steel sheet for PCM steel sheet, it is urgent to develop PVC-free hotmelt film to replace PVC film. In addition, a large amount of adhesive is used in the conventional film adhering process, and the adhesive contains a large amount of volatile organic compounds (VOC) (several tens% or more), and a large amount of VOC is released during the adhering process.
상기 문제점을 해결하기 위한 본 발명의 하나의 목적은 염소를 포함하지 않는 친환경 열용융 필름용 조성물을 제공하는 것이다.One object of the present invention to solve the above problems is to provide a composition for an environmentally friendly hot melt film containing no chlorine.
본 발명의 다른 목적은 접착강도, 박리한계성, 가공성, 내습성이 우수한 열용융 필름용 조성물을 제공하는 것이다.Another object of the present invention is to provide a composition for a hot-melt film excellent in adhesive strength, peeling limit, workability and moisture resistance.

적외선 분광 분석(Infrared spectroscopy ( FTIRFTIR Analysis) Analysis)
제조된 필름을 시편 거치대에 고정하고 적외선 부분에 올려놓은 뒤 측정하여 데이터를 얻었다. 측정된 데이터인 도 1을 확인하면 =C-H가 3000cm- 1이상에서 확인되며 -CH는 2900cm-1 부근에 나타나며 SIS의 isoprene의 이중결합 옆의 -CH3는 900cm-1에서 나타나는 것으로 각 필름이 SEBS, SBS, SIS임을 확인할 수 있다. The prepared film was fixed on the specimen holder and placed on the infrared part, and the data were obtained by measurement. If the check of the measured
만능시험기 분석Universal testing machine analysis
제조된 필름을 Dog born 모양의 틀을 사용하여 핫프레스로 실온에서 1ton 압력으로 눌러 만능시험기용 시편을 제조하였다. 만능시험기의 100N 로드셀 사이에 Dog born 모양의 시편을 표점거리 35mm로 거치하고 Cross head speed 20mm/min으로 실험을 진행하여 데이터를 얻었다. 측정된 데이터인 도 2 내지 5를 참고하면, MAH-SEBS와 AA가 동일할 때 PEAA가 증가할수록 최대하중(N)값은 증가하고 연신율은 감소한다. 또한, SEBS와 PEAA의 함량이 일정한 상태에서는 MAH-SEBS만 함유된 경우에 더 좋은 최대하중 값을 갖는 것을 확인 할 수 있다.The prepared film was pressed by hot press at room temperature under 1 ton pressure using Dog born mold. A dog born specimen was mounted between the 100N load cells of the universal testing machine at a gauge length of 35 mm and the experiment was conducted at a cross head speed of 20 mm / min. Referring to the measured data, FIG. 2 to FIG. 5, as the PEAA increases when MAH-SEBS and AA are the same, the maximum load (N) value increases and the elongation decreases. In addition, it can be confirmed that when the content of SEBS and PEAA is constant, a better maximum load value is obtained when only MAH-SEBS is contained.
필름 film 라미네이션Lamination
실시예 1 내지 33에서 제조한 열가소성 엘라스토머 조성물 필름을 사용하여 아래와 같은 방법으로 장식강판을 제조하였다. 핫프레스로 제조된 필름의 두께가 100um 미만이 되도록 하고 PET 필름의 금속박막층 부분에 접착한 후 라미네이션 기기 윗부분 롤러에 거치하고 또 다른 부착제인 강판을 기기에 놓고 롤러에 열을 가한 상태에서 롤러 사이를 천천히 통과시켜 장식강판을 제조하였다. 도 6 내지 9를 참조하면 보면 SEBS1과 SEBS2가 SIS와 SBS에 비해 이종소재간 접착이 우수한 것으로 보아 이 두 시료에 사용된 SEBS(KRATON G1657MS, G1726MS)가 접착력을 상승시켜주는 것으로 확인할 수 있다.Using the thermoplastic elastomer composition films prepared in Examples 1 to 33, a decorative steel sheet was produced in the following manner. The thickness of the film produced by the hot press is less than 100 袖 m. After adhering to the metal thin film layer of the PET film, the laminate is placed on the upper roller of the lamination apparatus. Another sheet of steel is placed on the apparatus. And then slowly passed to manufacture a decorative steel sheet. 6 to 9, SEBS1 and SEBS2 show superior adhesion between different materials compared to SIS and SBS, and SEBS (KRATON G1657MS, G1726MS) used in these two samples shows an increase in adhesion.
에릭센Eric Sen 시험( exam( ErichsenErichsen Test) Test)
도 6 내지 8을 참고하면 장식 강판을 폭 5mm로 강판 층까지 cross cut 후 cupping tester 사이에 시편을 거치하여 20mm/min 속도로 압력을 가한 후 시편의 박리정도를 확인하여 이종 소재 사이에서의 접착력을 확인 할 수 있다. 에릭센 테스트 결과는 부착된 면이 완벽하게 벌어지는 경우와 약간의 힘을 가할 시에 cross cut 부분이 약간 벌어지는 경우로 확인되고 SEBS1과 SEBS2 샘플의 PEAA함량이 10%와 20% 일 때는 부착된 면이 약간 벌어지며, 30%와 40%일 때 가장 작게 벌어지는 형태가 나타났다. 이로써 접착샘플의 PEAA 함량이 30%와 40%인 경우에 이종소재간 접착성이 가장 우수한 것을 확인할 수 있다. 6 to 8, the decorative steel sheet was cross-cut to a steel sheet with a width of 5 mm, and then the specimen was mounted between cupping tester, and the pressure was applied at a rate of 20 mm / min. Can be confirmed. The Ericksen test results show that the attached face is fully open and the cross cut area is slightly worn when applying some force. When the PEAA content of the SEBS1 and SEBS2 samples is 10% and 20%, the attached face Slightly widened, and 30% and 40%, respectively. As a result, when the PEAA content of the adhesive sample is 30% and 40%, it can be confirmed that the adhesion between the different materials is the most excellent.
