본 발명은 엠보싱 마스터롤을 이용하여 필름원단의 표면에 자외선경화도료로 된 엠보싱 코팅층을 형성시키는 코팅방법에 관한 것이다.The present invention relates to a coating method of forming an embossed coating layer of ultraviolet curable paint on the surface of a film fabric using an embossing master roll.

일반적으로 상품을 포장하는 필름원단의 표면에 인쇄된 인쇄면을 보호하기 위하여 자외선경화도료를 코팅하고 있으며, 또는 자외선경화도료를 필름원단의 표면에 공급한 다음 엠보싱이 형성된 마스터롤로서 압착시킴과 동시 자외선건조기로 건조시키는 방법으로 필름원단의 표면에 자외선경화도료를 코팅시키면서 엠보싱 코팅을 형성시키는 것이 소개된 바 있는데, 상기한 엠보싱 마스터롤에 의해 형성된 엠보싱 코팅층은 그 자체가 인쇄무늬를 나타내는 인쇄면이 되게 하거나 또는 엠보싱 코팅층의 각 엠보싱들이 일정한 곡률로 형성되어 빛의 투과 및 반사 굴절각도를 규칙적으로 확대시키는 빛확산면이 되게 하는 작용을 하므로서 필름원단에 코팅되는 자외선경화도료 코팅층을 엠보싱 마스터롤을 이용하여 엠보싱처리하는 방법을 많이 채택하고 있다.Generally, UV curable paint is coated to protect the printed surface on the surface of the film fabric to package the goods, or UV curable paint is supplied to the film fabric and then pressed into a master roll with embossing. It has been introduced to form an embossed coating by coating an ultraviolet curable paint on the surface of the film fabric by drying with an ultraviolet dryer. The embossed coating layer formed by the embossing master roll has a printed surface which itself shows a printed pattern. Or the embossing master roll is applied to the UV curable coating layer coated on the film fabric by acting to form a light diffusing surface which regularly increases the transmission and reflection refraction angles of light by forming each embossing of the embossing coating layer at a constant curvature. Adopt a lot of embossing methods There.

종래 기술은 필름원단에 자외선경화도료로 된 엠보싱 코팅층을 형성시키기 위하여 도 4 및 도 5에 도시된 바와 같은 방법을 사용하고 있다.The prior art uses the method as shown in Figs. 4 and 5 to form an embossed coating layer of ultraviolet curable paint on the film fabric.

도 4에 도시된 방법은, 구동로울러(100)와 연동로울러(101)에 엠보싱(102)이 연속적으로 형성된 투명한 엠보싱 벨트(103)를 연설하고, 상기 벨트의 내측에 벨트의 하부를 평탄하게 눌러주는 수개의 가이드 로울러(104)와 자외선램프(105)를 설치한 다음 상기 엠보싱 벨트(103)의 하부측으로 필름원단(106)을 이송시킴에 있어 상기 구동로울러(100) 전방측에 설치된 자외선경화도료 저장통(107)에서 필름원단(106)의 상면에 자외선경화도료(108)를 공급하므로서 자외선경화도료(108)가 필름원단(106)의 표면에 코팅됨과 동시 상기 엠보싱 벨트(103)의 엠보싱(102)에 의하여 엠보싱 코팅층(109)이 형성되면서 이송되는 것인데, 이같이 엠보싱 벨트(103)의 회전작동에 따라 엠보싱이 형성되면서 이송되는 엠보싱 코팅층(109)은 자외선램프(105)를 통과하는 과정에서 자외선에 노출되어 경화되므로서 상기 엠보싱 벨트(103)를 통과한 필름원단(106)의 표면에 코팅된 자외선경화도료(108)와 엠보싱 코팅층(109)이 형성되게 하는 코팅방법이며,In the method shown in Figure 4, the drive roller 100 and the interlocking roller 101, the embossing 102 is formed in succession to the transparent roller embossed 102, and press the lower portion of the belt flat inside the belt After installing several guide rollers 104 and ultraviolet lamps 105, the ultraviolet curing paint installed on the front side of the driving rollers 100 in transferring the film fabric 106 to the lower side of the embossing belt 103. The UV curable paint 108 is coated on the surface of the film fabric 106 while supplying the UV curable paint 108 to the upper surface of the film fabric 106 in the reservoir 107 and simultaneously embossing 102 of the embossing belt 103. The embossed coating layer 109 is formed by being transferred to the embossed coating layer 109, and thus the embossed coating layer 109 is transferred to the ultraviolet rays in the process of passing through the ultraviolet lamp 105. Exposed Since curing is standing and coating method of the ultraviolet-curing coating material 108 and the embossing coating layer 109 coated on the surface of the film, the fabric 106, passing through the embossing belt 103 is to be formed,

도 5에 도시된 방법은, 공급보빈(200)에 감긴 투명한 필름원단(201)을 엠보싱(202)이 형성된 엠보싱 로울러(203)로 공급함에 있어 상기 엠보싱 로울러(203)의 전방측에 설치된 자외선경화도료 저장통(204)에서 자외선경화도료(205)를 공급하도록 하므로 필름원단(201)에 자외선경화도료(205)가 일정한 두께로 코팅된 상태로 엠보싱 로울러(203)를 통과하는 과정에서 엠보싱 코팅층(206)이 형성됨과 동시 자외선램프(207)의 자외선에 노출되어 경화된 후 되감기 보빈(208)에 되감는 방법으로 되어 있다.In the method shown in FIG. 5, the ultraviolet cured film provided on the front side of the embossing roller 203 in supplying the transparent film fabric 201 wound around the supply bobbin 200 to the embossing roller 203 having the embossing 202 formed therein. In order to supply the ultraviolet curable paint 205 from the paint reservoir 204, the embossed coating layer 206 in the process of passing through the embossing roller 203 in a state in which the ultraviolet curable paint 205 is coated with a predetermined thickness on the film fabric 201. ) Is formed and exposed to ultraviolet rays of the ultraviolet ray lamp 207 and cured, and then rewinded to the rewind bobbin 208.

그러나 상기와 같이 필름원단(106)(201)에 자외선경화도료를 미리 도포시킨 상태에서 엠보싱 벨트(103) 및 엠보싱 로울러(203)로 필름원단을 이송시키게 되면 엠보싱 코팅층(109)(206)의 엠보싱 즉, 양각부분과 음각부분이 정밀하게 형성되지 않고 변형되어 나타나는 문제점이 있다.However, when the film fabric is transferred to the embossing belt 103 and the embossing roller 203 in the state of applying the ultraviolet curable paint to the film fabrics 106 and 201 as described above, the embossing of the embossing coating layers 109 and 206. That is, there is a problem that the embossed portion and the intaglio portion are deformed without being precisely formed.

즉, 엠보싱 벨트(103)과 엠보싱 로울러(203)는 대기에 노출된 상태이므로 그들의 표면에 형성된 엠보싱(102)(202)들 사이의 공간(S)에는 공기가 존재하고 있는 상태이며, 이같은 상태에서 엠보싱 벨트(103) 및 엠보싱 로울러(203)에 필름원단이 진입될 때 엠보싱(102)(202)이 자외선경화도료(108)(205)를 압착하기 시작하게 되는데, 이때 상기한 엠보싱(102)(202)들 사이의 공간(S)에 있는 공기가 외부로 빠져나가지 못하고 있는 상태에서 엠보싱(102)(202)이 자외선경화도료를 압착하게 되므로 공간(S)에 존재하던 공기는 상기 엠보싱의 압착작용에 의해 형성되는 엠보싱 코팅층(109)(206)에 형성되는 각 엠보싱에 의하여 압축되며, 이같이 압축되는 공기는 상기한 공간(S)의 끝부분에 압축공기층(a)으로 존재하는 상태에서 자외선램프(105)(207)에 의해 경화되게 된다. 이와같이 압축공기층(a)이 형성된 상태에서 경화된 엠보싱 코팅층(109)(206)의 각 엠보싱들은 엠보싱 벨트(103) 및 엠보싱 로울러(203)의 엠보싱(102)(202)들 사이에 형성된 공간(S)에 충전된 상태로 형성되지 못하고 상기한 압축공기층(a)만큼은 형성되지 않고 변형된 상태로 형성되는 문제점이 있게 된다.That is, since the embossing belt 103 and the embossing roller 203 are exposed to the atmosphere, air is present in the space S between the embossing 102 and 202 formed on their surface. When the film fabric enters the embossing belt 103 and the embossing roller 203, the embossing 102, 202 starts to squeeze the UV curable paint 108, 205, wherein the embossing 102 ( Since the air in the space (S) between the 202, the embossing (102) 202 compresses the UV curable paint in a state that does not escape to the outside, the air present in the space (S) is the compression action of the embossing Compressed by each embossing formed in the embossed coating layer (109, 206) formed by the UV lamp in the state that the compressed air is present as a compressed air layer (a) at the end of the space (S) 105) (207). Each embossing of the embossed coating layer 109, 206 cured in the state where the compressed air layer a is formed is formed between the embossing belt 103 and the embossing 102, 202 of the embossing roller 203. ) Is not formed in a state filled in the () and is not formed as much as the compressed air layer (a) there is a problem that is formed in a deformed state.

즉, 엠보싱 코팅층(109)(206)은 엠보싱(102)(202)의 양각부분에 의하여 형성되는 엠보싱의 음각부분은 원하는 형상으로 정밀하게 형성되는 반면 공간(S)에 의하여 형성되는 엠보싱의 양각부분은 압축공기층(a)에 의해 원하는 형상으로 정밀하게 형성되지 못하게 되며, 이렇게 엠보싱 코팅층(109)(206)을 형성하는 각 엠보싱의 양각부분이 변형된 상태로 형성될 경우에는 필름원단에 나타내고자 하는 엠보싱 인쇄무늬가 정밀하게 재생되지 않게 되는 문제점이 있게 되며, 또한 필름원단을 렌즈나 프리즘 등의 광학기기에 부착하여 빛의 투과 및 반사 굴절각도를 확대시키고자 할 때 빛의 굴절각도가 불규칙해져 광학기기에 사용할 수 없게 되는 문제점이 있게 된다.That is, the embossed coating layers 109 and 206 are embossed portions of the embossing formed by the embossed portions of the embossed 102 and 202, while the embossed portions of the embossed portion formed by the space S are precisely formed in a desired shape. Is not precisely formed into a desired shape by the compressed air layer (a), and when the embossed portion of each embossing forming the embossed coating layers 109 and 206 is formed in a deformed state, There is a problem that the embossed printed pattern is not reproduced precisely, and when the film fabric is attached to an optical device such as a lens or a prism to increase the transmission and reflection angle of light, the angle of refraction of the light becomes irregular and optical There is a problem that can not be used in the device.

본 발명은 상기와 같은 종래 기술의 제반 문제점을 감안하여 창출한 것으로, 필름원단에 코팅된 자외선경화도료에 엠보싱 코팅층을 정밀하게 형성시킬 수 있게 하는 방법을 제공하므로서 필름원단에 코팅된 엠보싱 인쇄무늬가 정확하게 재생될 수 있도록 함과 아울러 광학기기에 사용하였을시 빛의 투과 및 반사 굴절각도를 규칙적으로 확대시킬 수 있도록 하는 엠보싱 필름원단을 생산할 수 있도록 하는데 목적을 두고 발명한 것이다.The present invention was created in view of the above-mentioned problems of the prior art, and provides an embossed printed pattern coated on the film fabric by providing a method for precisely forming the embossed coating layer on the UV-curable coating coated on the film fabric. The invention was invented for the purpose of producing an embossed film fabric that can be accurately reproduced and can also regularly enlarge the transmission and reflection refraction angles of light when used in optical devices.

When the hardened paint 8 is adhered to the surface of the film raw material 3 supplied through the inlet roller 4, the cured paint 8 is adhered by being pressed by the pressing action of the embossing master roll 1 and the inlet roller 4. Embossed embossed portion 91 of embossed coating layer 9 formed by embossing 2. The intaglio portion 92 is precisely formed, and thus the embossed coating layer 9 in which the embossing is precisely formed passes through the ultraviolet dryer 6 while being rotated and moved together with the film fabric 3, wherein the film fabric 3 ) Is a transparent material, so that the UV-curable coating is exposed by ultraviolet rays irradiated from the UV dryer 6, the embossed coating layer 9 is cured for a short time passing through the UV dryer 6 and simultaneously to the film fabric 3 Strong adhesion.

상기와 같이 필름원단(3)에 점착되고 경화된 엠보싱 코팅층(9)은 인출로울러(5)를 통과할 때 엠보싱 마스터롤(1)에서 이완되므로서 필름원단(3)에는 엠보싱 코팅층(9)이 점착된 채 되감기 보빈으로 이송되는 것이며, 또한 상기한 엠보싱 코팅층(9)에는 양각부분(91)과 음각부분(92)이 정밀한 엠보싱이 형성되는 것이다. 따라서 필름원단(3)에 형성되는 엠보싱 코팅층(9)을 이용하여 인쇄무늬를 형성하고자 할 때 인쇄무늬를 정확하고 선명하게 재생시킬 수 있는 특징이 있으며, 또는 광학기기에 적용하여 빛의 투과 및 반사 굴절각도를 확대시키고자 할 경우에도 필름원단에 형성되는 엠보싱 코팅층(9)의 양각부분(91)과 음각부분(92)이 정밀하게 형성시킬 수 있어 빛의 투과 및 반사 굴절각도가 불규칙적으로 일그러지는 현상 없이 규칙적으로 정확하게 확대시킬 수 있는 특징을 나타내는 것이다.The embossed coating layer 9 adhered to the film fabric 3 and cured as described above is relaxed on the embossing master roll 1 when passing through the drawing roller 5, so that the film fabric 3 has an embossed coating layer 9 on it. It is transported to the rewind bobbin while sticking, and the embossed coating layer 9 is formed with precise embossing of the embossed portion 91 and the engraved portion 92. Therefore, when the printed pattern is to be formed using the embossed coating layer 9 formed on the film fabric 3, the printed pattern can be accurately and clearly reproduced, or applied to an optical device to transmit and reflect light. Even if the angle of refraction is to be enlarged, the embossed portion 91 and the intaglio portion 92 of the embossed coating layer 9 formed on the film fabric can be precisely formed so that the transmission and reflection refractive angles of the light are irregularly distorted. It is a characteristic that can be enlarged regularly and accurately without phenomenon.

상기와 같은 본 발명에 의하면 엠보싱이 형성된 엠보싱 마스터롤 외주에 자외선경화도료를 직접 코팅시키는 수단으로서 상기 엠보싱들 사이에 형성된 공간에 공기층이 없이 자외선경화도료가 충진된 상태로 이송되면서 필름원단의 표면에 점착되면서 경화되게 하므로서 필름원단에 코팅된 자외선경화도료에 형성되는 엠보싱 코팅층의 음각부분은 물론이고 양각부분까지도 정밀하게 형성되게 하는 효과가 있으므로 엠보싱 코팅층을 인쇄면으로 할 경우 소정의 원하는 인쇄무늬를 정확하게 나타나게 하는 포장용 필름원단을 제공할 수 있게 하는 효과가 있고, 또 엠보싱 코팅층을 광학기기의 부품으로 사용되는 렌즈, 프리즘의 표면에 부착하여 빛의 투과 및 반사 굴절각도를 확대시키기 위한 파형 또는 산형 모양을 형성시키고자 할 경우에는 그 파형 및 산형 모양을 정밀하게 형성시킬 수 있으므로 정밀한 곡률을 갖는 엠보싱 필름원단을 제공할 수 있게 하는 효과를 가져다주는 발명인 것이다.According to the present invention as described above as a means for directly coating the UV curable paint on the outer circumference of the embossing master roll embossed is formed without the air layer in the space formed between the embossing to the surface of the film fabric while being filled with UV curable paint Since it is hard to adhere and harden, it has the effect of precisely forming not only the intaglio portion but also the embossed portion of the embossed coating layer formed on the UV-curable coating coated on the film fabric.
