Description
본 발명은 야외 깔판용 PE발포원단에 OPP필름의 합지장치에 관한 것이며 폴리에틸렌 합성수지(PE)를 압출 발포공법으로 원단을 성형 제조하는 일면에는 하이덴 필름을 열접착으로 합지하고, 또 다른 일면에는 OPP, PET 또는 LDPE필름을 액상접착제로 코팅하여 가열 가압으로 합지하는 일련의 작업을 연속으로 할 수 있도록 한 것이다.The present invention relates to a laminating apparatus of OPP film to PE foam fabric for outdoor pallets, and one side to manufacture the fabric by molding the polyethylene synthetic resin (PE) by extrusion foaming method, the laminated HEIDEN film by thermal bonding, the other side OPP, PET or LDPE film is coated with a liquid adhesive so that a series of operations of laminating by heat and pressure can be performed continuously.
야외용 깔판은 폴리에틸렌합성수지(PE)를 용해하여 압출과 동시에 발포공정을 거쳐 PE발포원단을 구성하고 동 PE발포원단의 일면에는 폴리에틸렌 타포린 직조물의 전후면에 폴리에틸렌(PE수지)을 코팅한 원단을 위치시켜 접착부위를 가열하여 가압로울러로 합지하고, 또 다른 일면에는 폴리에틸렌수지(PE) 필름 위에 인쇄하고 인쇄층 위에 필름코팅된 필름을 위치시켜 접착부위를 가열하고 가압로울러를 통과 합지시켜 야외깔판용 원단을 제조하며 동 원단을 규격으로 재단하고 테두리에 보호 테이프를 씌우고 봉제하여 야외용 깔판을 제조하게 된다.The outdoor pallet dissolves the polyethylene synthetic resin (PE) and forms the PE foaming fabric through extrusion and foaming process, and on one side of the PE foaming fabric is placed a fabric coated with polyethylene (PE resin) on the front and back of the polyethylene tarpaulin fabric. Heat the adhesive area and laminate it with a pressure roller. On the other side, print on a polyethylene resin (PE) film and place a film-coated film on the printing layer to heat the adhesive area and laminate it through a pressure roller to make an outdoor pallet fabric. It manufactures outdoor pallet by cutting the fabric to the standard and covering and sewing the rim with a protective tape.
또 다른 수단으로는 PE발포원단의 일면에는 폴리에틸렌 필름을 가열가압으로 합지하고, 또 다른 일면에는 OPP필름, PET필름, LDPE필름등에 인쇄 또는 전사하고 접착부위에는 접착이 용이한 별도의 PE수지를 코팅하여 구성한 필름을 위치시켜 접착부위인 PE코팅 부위를 가열하고 이를 엠보싱 가압로울러로 합지하여 야외용 깔판 원단을 제조하고 동 원단을 규격으로 재단하여 테두리에 보호테이프를 씌우고 봉제하여 야외용 깔판을 제조하고 있다.As another means, one side of the PE foam fabric is laminated with polyethylene film by heating and pressure, and the other side is printed or transferred onto OPP film, PET film, LDPE film, etc., and the separate PE resin is easily coated on the adhesive part. By placing the film constructed by heating the PE coated portion of the adhesive portion and laminated it with an embossed pressure roller to manufacture the outdoor pallet fabric, and cut the fabric to the standard by applying a protective tape to the rim to manufacture the outdoor pallet.
이와 같은 종래의 수단들은 폴리에틸렌수지(PE)를 압출발포공정으로 PE발포원단을 성형제조하고 동 원단의 전후면에 위치시켜 합지하는 필름에는 PE발포원단과 용융접착이 용이한 소재로 코팅하고 접착부위인 코팅부위를 가열하고 PE발포원단에 가압으로 접착하는 수단으로 합지시켜 제조되므로서 표면 필름으로 PE수지필름을 사용하게 될 경우 인쇄 또는 전사상태가 우수하지 못하여 인쇄 또는 전사상태가 우수한 OPP나 PET 또는 LDPE 소재의 필름을 사용하게 되나 동 소재는 PE발포원단과의 접착성이 떨어져 OPP나 PET 또는 LDPE등 소재의 필름에는 PE발포원단과의 접착면에 PE코팅으로 전처리작업을 수행하고 코팅된 접착면을 다시 가열시켜 가압로울러에서 합지하게 되므로 작업공정이 많아 원가상승의 요인이 되고, 또 PE발포원단과 표면 필름간을 합지하기 위하여 가열하고 가압에 의한 열접착이 이루어지므로서 접착층에는 경화층을 가지게 되고 소재의 신장율이 다르게 되어 계절변화와 반복사용과정에서 PE발포원단과 표면필름간에는 경화부위가 이격되는 현상이 발생되어 야외용 깔판을 장구히 사용하지 못하는 결점으로 지적되고 있다.Such conventional means are formed by manufacturing a polyethylene foam (PE) PE extrusion fabric by extrusion foaming process and placed on the front and back surfaces of the fabric and coated with a PE foam fabric and a material that is easily melt-bonded and bonded to the film It is manufactured by laminating the phosphorus coating part by means of adhesive bonding to PE foaming fabric. When PE resin film is used as a surface film, the printing or transfer state is not good, so the printing or transfer state is excellent in OPP or PET or LDPE film is used, but the material is not adhesive with PE foaming material, and pre-treatment with PE coating on the adhesive surface with PE foaming material on OPP, PET or LDPE film is coated. The material is heated again, and then laminated in a pressurized roller, which increases the number of working processes and increases the cost. In order to be heated and pressurized, the adhesive layer has a hardened layer, and the elongation of the material is different, so that the hardened part is separated from the PE foam fabric and the surface film during the seasonal change and repeated use. It is pointed out as a defect that can not be used for a long time.
이에 본 발명은 인쇄나 전사상태가 우수한 OPP나 PET 또는 LDPE를 소재로 한 필름을 PE발포원단에 접착할 때 OPP나 PET 또는 LDPE필름의 일면에 접착제를 도포하여 가압로울러로 합지하는 PE발포원단에 필름 합지공정을 개선하는데 주된 목적이 있고 저렴한 원가로 양산 제조하고 소재의 신장율 변화에 따라 이격되는 현상을 해소하여 야외용 깔판으로 사용시 장구히 사용할 수 있도록 하는데 부수적인 목적이 있다.Therefore, the present invention is applied to the PE foaming fabric by applying an adhesive to one surface of the OPP, PET or LDPE film when bonding a film made of OPP, PET or LDPE material with excellent printing or transfer state to the PE foaming fabric The main purpose is to improve the film lamination process and to mass produce at low cost and to eliminate the phenomenon of separation according to the change of elongation rate of the material so that it can be used for long time when used as outdoor pallet.
