일반적으로 피혁용 필름은 천연피혁에 합지되어 피혁의 표면을 이루는 피복용으로 사용되거나 부직포 등의 섬유와 합지되어 인조피혁을 형성하게 되며, 합지된 원단은 필요에 의하여 재단되어 가방이나 신발, 의류, 벨트 등의 용도로 사용된다.In general, the film for leather is used as a coating for forming the surface of the leather by laminating with natural leather, or laminated with fibers such as non-woven fabrics to form artificial leather, and the laminated fabric is cut as needed to produce bags, shoes, clothing, Used for purposes such as belts.

이러한 용도로 사용되는 피혁용 필름은 폴리우레탄 폼(Polyurethane Foam)을 기초로 하는 열경화성 수지로 제조되어 왔다.Leather films used for this purpose have been made of a thermosetting resin based on polyurethane foam (Polyurethane Foam).

열경화성 수지로 제조되는 종래의 피혁용 필름은 내열성은 우수하나, 내마모성, 인장강도 및 저온 굴곡성 등이 취약하여 긁히거나 찢어지기 쉬우며, 겨울철 기타 저온의 환경에서는 사용이 매우 불편한 문제점이 있다.Conventional leather film made of a thermosetting resin is excellent in heat resistance, but abrasion resistance, tensile strength and low temperature bendability is vulnerable to easy to scratch or tear, there is a problem that is very inconvenient to use in winter or other low temperature environment.

이에 본 고안은 상기와 같은 종래의 필름에 대한 문제점을 해결하기 위하여 고안된 것으로, 필름을 열가소성 수지층과 열경화성 수지층을 포함하는 것으로 하여 내열성은 물론 내마모성, 인장강도 및 저온 굴곡성이 우수한 피혁용 필름을 제공하는데에 그 목적이 있다.The present invention is designed to solve the problems of the conventional film as described above, the film comprising a thermoplastic resin layer and a thermosetting resin layer to a film for leather excellent in heat resistance, wear resistance, tensile strength and low temperature bendability The purpose is to provide.

각 층의 두께는 필요에 따라 적절하게 선택될 수 있으며, 바람직하게는 열경화성 폴리우레탄 수지층(10)이 0.05 ±0.02㎜, 접착제층(20)이 0.03 ±0.01㎜, 열가소성 폴리우레탄 수지층(30)이 0.3 ±0.1㎜로 형성하는 것이 좋다.The thickness of each layer may be appropriately selected as necessary. Preferably, the thermosetting polyurethane resin layer 10 is 0.05 ± 0.02 mm, the adhesive layer 20 is 0.03 ± 0.01 mm, and the thermoplastic polyurethane resin layer 30 ) Should be 0.3 ± 0.1 mm.

상기의 구성에 의하여 본 고안 필름(100)은 열가소성 폴리우레탄 수지의 장점 즉 내마모성, 인장강도, 저온 굴곡성과 열경화성 폴리우레탄 수지의 장점 즉 내열성을 동시에 만족하게 된다.By the above configuration, the subject innovation film 100 satisfies the advantages of the thermoplastic polyurethane resin, that is, the wear resistance, the tensile strength, the low temperature flexibility, and the heat resistance of the thermosetting polyurethane resin.

도 2 및 도3은 상기 본 고안에 적용되는 열가소성 폴리우레탄 수지(10)의 제조공정과, 제조된 열가소성 폴리우레탄 수지(20)에 상기 열경화성 폴리우레탄 수지(30)를 접합하는 공정을 도시한다.2 and 3 illustrate a manufacturing process of the thermoplastic polyurethane resin 10 applied to the present invention and a process of bonding the thermosetting polyurethane resin 30 to the manufactured thermoplastic polyurethane resin 20.

우선 도 2는 본 고안에 적용되는 열가소성 폴리우레탄 수지(10)의 제조공정도로서 본 도면에 따르면, 혼합기에서 열가소성 폴리우레탄 수지를 적량의 첨가제와 혼합하는 혼합단계(11)과, 온열롤을 이용하여 약 200℃의 온도를 유지하면서 압착롤러로 이송시키는 공급단계(12)와, 압착롤러를 이용하여 일정한 두께로 압연하는 동시에 일면에 미세한 엠보싱을 형성하는 압출단계(13)와, 냉각롤을 이용하여 냉각하고 폭을 맞추는 후처리단계(14)를 차례로 거쳐 상기 열가소성 폴리우레탄 수지(10)가 제조되는 것이며, 최종적으로 롤(15)의 형태로 감아진다.First, FIG. 2 is a manufacturing process diagram of a thermoplastic polyurethane resin 10 applied to the present invention. According to this drawing, a mixing step 11 of mixing a thermoplastic polyurethane resin with an appropriate amount of an additive in a mixer, and using a thermal roll, is used.

일반적인 열가소성 폴리우레탄 수지는 그 자체로는 내열성이 약하여 독립하여 피혁용 필름으로 사용될 수 없다. 따라서 내열성이 강한 열경화성 폴리우레탄 수지를 접합할 필요가 있으며 이때 필요적으로 접착제가 사용된다.In general, the thermoplastic polyurethane resin itself is weak in heat resistance and cannot be used independently as a film for leather. Therefore, it is necessary to bond a heat-resistant thermosetting polyurethane resin, wherein an adhesive is used as necessary.

한편으로, 일반적인 열가소성 폴리우레탄 수지는 내화학성이 강하므로 통상의 수지 접착제에 의한 접착력이 약하다.On the other hand, the general thermoplastic polyurethane resin is weak in the adhesive strength by the usual resin adhesive because of the high chemical resistance.

따라서 상기 혼합단계(11)에서 통상의 열가소성 폴리우레탄 수지에 접착제와의 접착력이 강한 첨가제를 혼합하는 것이며, 이 때 혼합되는 첨가제는 폴리에스테르(Polyester), 폴리아미드(Polyamide), 피브이씨 컴파운드(PVC Compund) 중에서 1이상 선택적으로 사용한다.Therefore, in the mixing step 11, an additive having a strong adhesive strength with an adhesive is mixed with a conventional thermoplastic polyurethane resin, and the additives mixed at this time are polyester, polyamide, and FBC compound. Optionally use at least one of PVC Compunds).

또한, 상기 압출단계(13)에서 열가소성 폴리우레탄 수지(10)의 일면에 미세한 엠보싱을 형성하는 것도 접착표면을 넓게하여 접착력을 강화하기 위함이다.In addition, forming fine embossing on one surface of the thermoplastic polyurethane resin 10 in the extrusion step 13 is to enhance the adhesive strength by widening the adhesive surface.

도 3은 열경화성 폴리우레탄 수지(30)를 제조하는 공정과 상기 도 2의 공정에 의하여 제조된 상기 열가소성 폴리우레탄 수지(10)를 접합하는 공정을 도시한다.FIG. 3 illustrates a process of manufacturing the thermosetting polyurethane resin 30 and a process of bonding the thermoplastic polyurethane resin 10 manufactured by the process of FIG. 2.
