Description
본 발명은 다양한 문양의 전사용 필름을 다양한 재료의 요철면위에 전사하 방법에 관한 것이다. 좀 더 구체적으로, 본 발명은 철, 알루미늄, 플라스틱, 세라믹, 고무 및 유리 등의 다양한 요철면에 열팽창 및 흡착공정을 이용하여 전사필름 자체에 인쇄된 모양을 변형시키지 않고 간단히 전사하는 방법에 관한 것이다.The present invention relates to a method for transferring transfer films of various patterns onto uneven surfaces of various materials. More specifically, the present invention relates to a method of simply transferring without deforming the shape printed on the transfer film itself by using a thermal expansion and adsorption process on various irregularities such as iron, aluminum, plastic, ceramic, rubber, and glass. .
물체의 표면에 문양을 인쇄(전사)하는 방법에 대한 종래의 기술에 대해서는 다음과 같은 문헌에 개시되어 있다.Conventional techniques for printing (transferring) patterns on the surface of an object are disclosed in the following documents.
대한민국 특허공고 제 91-2529호는 스크린 프린팅에 의한 페이스트를 적용하여 물체 표면에 음화형 무늬를 만든 후, 약 400℃ 이상의 온도에서 가열하고, 스크린 프린팅에 의해 코팅되지 않은 물체의 표면과 반응하는 금속산화물 용액애 음화형 무늬가 구비된 가열된 물체를 침지하고, 피복되지 않은 물체의 표면에 광택 문양을 형성한 후 음화형 무늬를 물체로부터 제거하므로써, 물체 표면에 광택 문양을 전사하는 방법을 개시하고 있다.Korean Patent Publication No. 91-2529 describes a negative pattern on an object surface by applying a paste by screen printing, and then heats it at a temperature of about 400 ° C. or higher and reacts with the surface of an uncoated object by screen printing. Disclosing a method of transferring a glossy pattern on the surface of an object by immersing a heated object having a negative pattern in an oxide solution, forming a glossy pattern on the surface of the uncoated object, and then removing the negative pattern from the object. have.
아울러, 일본 특허공고 소화 제 52-41682호 및 제 57-50547호는 전사용 필름을 인쇄(전사)하여 여러 가지 물체의 표면에 문양을 인쇄하는 방법에 대해 개시하고 있다.In addition, Japanese Patent Laid-Open Nos. 52-41682 and 57-50547 disclose a method of printing (transferring) a transfer film to print a pattern on the surface of various objects.
그러나, 전술한 종래의 이러한 인쇄방법들은 인쇄(전사) 공정이 복잡하고 소재의 선택에 제한을 받는다는 문제점이 있었으며, 인쇄된 피복체의 내구성이 떨어져 탈색 내지는 변색되기 용이하고, 인쇄전에 인위적으로 물체 표면에 문양을 만들어야 하며, 고가의 인쇄 비용이 요구되므로, 실제적으로 사용하는 데에는 한계가 있었다.However, the above-described conventional printing methods have a problem in that the printing (transferring) process is complicated and the selection of materials is limited, and the printed coating is less durable and easily discolored or discolored. The design has to be made, and expensive printing costs are required, so there is a limit to the practical use.
한편, 이러한 종래기술의 한계성을 극복하고자 수전사 및 열전사 방식이 개발되었다.On the other hand, in order to overcome the limitations of the prior art, the hydrothermal and thermal transfer methods have been developed.
일반적으로, 수전사는 박질막에 도료 또는 인쇄잉크 등을 사용하여 패턴을 인쇄하고, 패턴이 인쇄된 박질막을 액체상에 띄우고, 상기 박질막에 물체를 눌러서 액압에 의해 상기 패턴을 물체표면에 전사하는 방식을 채용한다. 이러한 방식은 기본적으로 오브라이트와 같은 박질막위에 미려하고 색채감이 풍부한 모양을 인쇄하는 것이 사실상 불가능하기 때문에, 단순한 인쇄패턴밖에 얻을 수 없다는 단점이 있었다. 특히, 이 박질막으로 인쇄패턴을 전사하는 방법에 있어서는, 박질막이 물체의 섬세한 요철면에 인쇄패턴을 전사되는것이 어렵기 때문에 곡면에의 인쇄가 사실상 불가능하였다. 또한, 박질막은 인쇄패턴이 목적물에 전사된 후, 물리적 또는 화학적인 수단에 의해 제거하지 않으면 안되기 때문에, 공정이 복잡해지는 단점이 있는 동시에, 박질막의 제거수단에 의해 전사된 패턴이 손상되지 않도록 유의하는 배려가 요구되는 등 많은 단점을 가지고 있다.In general, a water-receiving machine prints a pattern on a thin film by using a paint or a printing ink or the like, floats the thin film on which the pattern is printed on a liquid, and transfers the pattern to an object surface by hydraulic pressure by pressing an object on the thin film. Adopt the method. This method basically has a disadvantage in that it is impossible to print a beautiful and colorful shape on a thin film such as an oblite, so that only a simple printing pattern can be obtained. In particular, in the method of transferring the printing pattern to the thin film, it is virtually impossible to print on the curved surface because it is difficult for the thin film to be transferred to the fine uneven surface of the object. In addition, since the thin film has to be removed by physical or chemical means after the printing pattern is transferred to the object, the process is complicated, and care must be taken not to damage the pattern transferred by the thin film removing means. There are many disadvantages, including the need for consideration.
한편, 일반적인 열전사 방법은 수지층에 이형제 성분의 수지와 셀룰로스 아세테이트(cellulose acetate), 메틸에틸케톤(MEK, methylethylketone), 에탄올, 톨루엔 등의 유기용제를 합성하여 도포하며, 수지층과 인쇄층의 균열을 방지하는 동시에 접착성의 향상을 도모할 수 있게 니트로셀룰로스(nitrocellulose) 등의 성분을 입히고, 그 위에 우레탄용 레진과 색소, 톨루엔, 메틸에틸케톤 등의 유기용제를 배합한 것으로, 인쇄를 한 필름을 프레스에서 열을 가하며 목적물에 압착하고서 수지층을 제거하는 방식을 채용한다. 그러나, 이러한 방식 역시, 압착 및 수지층 제거 공정 등이 복잡하며, 요철면의 전사가 어렵고, 또한, 전사된 목적물을 대량으로 생산하는데에는 문제점이 있었다.On the other hand, the general thermal transfer method is synthesized and applied to the resin layer of the resin of the release agent component, cellulose acetate (cellulose acetate), methyl ethyl ketone (MEK, methylethylketone), ethanol, toluene and the like, Nitrocellulose and other components are coated to prevent cracking and to improve adhesiveness, and the resin is printed by mixing urethane resin with organic solvents such as pigments, toluene and methyl ethyl ketone. Is pressed in the press and pressed to the target object to remove the resin layer. However, such a method also has a complicated process of pressing and removing the resin layer, which is difficult to transfer the uneven surface, and also has a problem in producing a large amount of the transferred object.
이에, 본 발명자들은 다양한 문양을 어떠한 요철면이라도 간단하게 전사할 수 있는 방법을 개발하기 위하여 예의 연구 노력한 결과, 전사필름의 열팽창 및 흡착성을 이용하여 생산성 및 상품성을 획기적으로 향상시킬 수 있는 전사방법을 개발하고, 본 발명을 완성하게 되었다.Accordingly, the present inventors have made a thorough research to develop a method for easily transferring various patterns to any uneven surface, and as a result, the transfer method can dramatically improve productivity and commerciality by using thermal expansion and adsorptivity of the transfer film. Developed and completed the present invention.
결국, 본 발명의 목적은 열팽창 및 흡착을 이용하여 다양한 문양을 다양한 요철면위에 전사필름을 간단히 전사시킬 수 있는 방법을 제공하는 것이다.After all, it is an object of the present invention to provide a method of simply transferring a transfer film onto a variety of irregularities by using a thermal expansion and adsorption.

본 발명에서 전사필름은 종래의 다양한 전사필름의 사용이 가능하나, 바람직하게는 본 발명자가 개발한 전사필름을 사용한다. 본 발명에서 전사필름은 제조된 전체 주필름층의 중량에 대하여, 물 40 내지 60%, 폴리비닐알콜(polyvinylalcohol, PVA) 22.5 내지 33.5%, 전분 8 내지 12%, 설탕 2 내지 4%, 비누 3 내지 7%, 아교 1 내지 3%, 라텍스 3 내지 7% 및 실리콘오일 0.5 내지 2%를 배합하여 80 내지 100℃에서 용해시킨 후, 두께 약 20 내지 100㎛으로 롤러에 넣고 3 내지 5m/min의 속도로 압인출하여 60 내지 80℃의 열풍조건에서 건조시키고 냉풍으로 냉각시킨 주필름층에, 그라비어, 옵셋 또는 실크스크린 인쇄 방법으로 목적하는 문양의 인쇄한 다음, 철, 알루미늄, 플라스틱, 세라믹, 고무 또는 유리 등의 전사하고자 하는 목적물에 따라, 투명 페인트, 락카, 프라이마 또는 수지 등의 유연성 물질을 코팅하여 제조한다(참조 : 동일자 출원하는『다양한 문양의 요철면용 전사필름 및 그의 제조방법』).In the present invention, the transfer film is possible to use a variety of conventional transfer film, preferably using a transfer film developed by the present inventors. In the present invention, the transfer film is water 40 to 60%, polyvinyl alcohol (polyvinylalcohol, PVA) 22.5 to 33.5%, starch 8 to 12%, sugar 2 to 4%, soap 3 with respect to the total weight of the main film layer To 7%, glue 1 to 3%, latex 3 to 7% and silicone oil 0.5 to 2% was mixed and dissolved at 80 to 100 ℃, put into a roller of about 20 to 100㎛ thickness of 3 to 5m / min The desired pattern was printed by gravure, offset, or silkscreen printing on the main film layer which was drawn out at a speed, dried under hot air conditions of 60 to 80 ° C. and cooled by cold air, and then iron, aluminum, plastic, ceramic, rubber Alternatively, according to the object to be transferred, such as glass, a flexible material such as transparent paint, lacquer, prima, or resin is coated to produce the same (see "A variety of patterns of uneven surface transfer film and its manufacturing method").
이하에서는, 전술한 전사필름을 가지고 본 발명에 의하여 다양한 요철면에 전사하는 방법을 공정별로 나누어 보다 구체적으로 설명하고자 한다.Hereinafter, the method of transferring the transfer film to the various uneven surfaces according to the present invention with the transfer film described above will be described in more detail.
제 1 공정 : 목적물의 세팅Step 1: setting the target
상부 및 하부에 열풍판 흡착기가 각각 구비된 열전사 장치에 전사하고자 하는 목적물을 요철면을 위로 하여 올려 놓고, 목적물위에 전사필름을 올려 놓는다.The target object to be transferred to the thermal transfer apparatus each equipped with a hot air plate adsorber on the upper and lower sides thereof is placed with the uneven surface upward, and the transfer film is placed on the target object.
제 2 공정 : 열풍으로 인한 전사필름 팽창Second Process: Transfer Film Expansion due to Hot Air
열전사 장치의 상부에 위치한 열풍판을 덮고, 50 내지 100℃, 보다 바람직하게는 70 내지 80℃의 열풍으로, 3분 내지 10분, 가장 바람직하게는 5분 정도 가열하여, 롤러로부터 풀려져 나온 전사필름을 1.2 내지 2배, 가장 바람직하게는 1.5배까지 팽창시킨다. 이때, 열풍온도가 상기 온도이상으로 과열되거나 팽창배수가 전기 범위를 상회하는 경우에는 전사필름의 손상이 초래되므로 유의하며 팽창시킨다.Covering the hot air plate located on the upper portion of the thermal transfer apparatus, and heated with a hot air of 50 to 100 ℃, more preferably 70 to 80 ℃, 3 to 10 minutes, most preferably about 5 minutes, and released from the roller The transfer film is expanded 1.2 to 2 times, most preferably 1.5 times. At this time, if the hot air temperature is overheated above the above temperature or the expansion drainage exceeds the electric range, the transfer film is damaged, so be careful and expand it.
제 3 공정 : 전사Third process: transfer
전기 열팽창 및 흡착 공정에서 전사필름의 팽창이 확인되면, 열전사 장치의 하부에 위치한 흡착기를 가동시켜 팽창된 전사필름이 목적물에 기포없이 부착되도록 한다. 그런 다음, 전사필름이 흡착된 목적물을 열전사 장치의 외부에 위치한 냉풍콘베이어로 이동하여 5 내지 15℃의 냉풍으로 냉각시켜 충분히 전사시킨다.When the expansion of the transfer film is confirmed in the electrical thermal expansion and adsorption process, the adsorber located in the lower portion of the thermal transfer apparatus is operated so that the expanded transfer film adheres to the object without bubbles. Then, the target object adsorbed by the transfer film is transferred to a cold wind conveyor located outside of the thermal transfer apparatus, cooled by 5 to 15 ° C. cold air, and sufficiently transferred.
전기 열전사 공정에서, 보다 바람직하게는, 롤러로부터 풀려져 나온 전사필름에 목적물의 특성에 맞는 신나 또는 본드를 입히는 공정 및 전사필름이 흡착된 목적믈을 냉풍콘베이어를 거쳐 수조속에 입수시키는 공정을 추가할 수도 있다.In the electrothermal transfer process, more preferably, a process of applying a thinner or bond to the transfer film released from the roller according to the characteristics of the object and a process of acquiring the object onto which the transfer film is adsorbed through a cold wind conveyor into the tank. You may.
이하에서는, 본 발명의 열팽창 흡착전사 방법을 종래의 수전사 방법과 첨부한 도면을 참조하여 보다 상세히 비교 설명한다.Hereinafter, the thermal expansion adsorption transfer method of the present invention will be described in detail with reference to the conventional water transfer method and the accompanying drawings.
도 1은 종래의 수전사 공정에 의한 전사방법을 나타내는 개략도이다. 도 1에서 보듯이, 목적물(1)의 크기에 적당한 수조(3)위에 다양한 문양의 인쇄된 전사필름(2)를 인쇄면을 위로 하여 물(4)위에 띄우고, 목적물(1)을 서서히 입수시키면 액압에 의해 목적물(1)에 전사가 이루어진다.1 is a schematic view showing a transfer method by a conventional water transfer process.
