본 발명은 기저시트에 금속박띠를 피복시키는 금속박 부분코팅 시트의 제조 방법에 관한 것으로, 특히 알루미늄박같이 전도성 및 유연성이 뛰어난 금속박띠를 기저시트의 소정 위치에 정교하게 밀착시키기 위한 금속박 부분코팅 시트의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a metal foil partial coating sheet for coating a metal foil on a base sheet, and particularly, to a metal foil partial coating sheet for precisely adhering a metal foil having excellent conductivity and flexibility, such as aluminum foil, to a predetermined position of the base sheet. It relates to a manufacturing method.
알루미늄과 같이 유연성이 뛰어난 금속박은 대개 쉽게 부식되고 절취되는 등의 문제점이 있으므로 금속박의 부식을 방지하기 위해 합성수지 필름으로 피복되고, 그 인장강도를 증기시키기 위해 합성수지사를 교차·직조한 기저시트에 접합된 금속박시트 형태로 제작되었다. 이러한 금속박시트는 대개 폴리에스테르 필름과 금속박 사이에 용융상태의 열가소성 합성수지를 부으면서 냉각·압연하여 금속박을 폴리에스테르 필름에 밀착시키고, 이 금속박을 소정 폭을 가진 금속박띠로 절개한 후, 상호 소정 간격을 두고 배열된 금속박띠와 교차직조된 기저시트 사이에 역시 용융상태의 열가소성 수지를 부으면서 냉각·압연하며, 마지막으로 금속박띠가 피복되지 않은 부분을 절개함으로써 제작되었다. 한편, 필요에 따라 문자나 도형이 인쇄된 폴리에스테르 필름을 사용하여 금속박 위에 일정한 메시지가 각인되게 할 수도 있었다.Flexible metal foils such as aluminum usually have problems such as being easily corroded and cut off, and are covered with a synthetic resin film to prevent corrosion of the metal foil, and the synthetic resin yarns are bonded to a cross-woven base sheet to vaporize the tensile strength thereof. It was produced in the form of a metal foil sheet. Such a metal foil sheet is usually cooled and rolled by pouring molten thermoplastic synthetic resin between the polyester film and the metal foil to bring the metal foil into close contact with the polyester film, and the metal foil is cut into a metal foil strip having a predetermined width and then spaced at a predetermined interval from each other. The molten thermoplastic resin was also cooled and rolled between the arranged metal foil and the cross-woven base sheet, and finally, the metal foil coated portion was cut out. On the other hand, if necessary, a constant message could be imprinted on the metal foil using a polyester film printed with letters or figures.
그러나 상기와 같은 종래의 금속박 부분코팅 시트의 제조방법은However, the manufacturing method of the conventional metal foil partial coating sheet as described above
첫째, 소정 폭을 가진 금속박띠를 상호 일정한 간격을 두고 배열시킨 상태에서 기저시트에 균일하게 접착시키기 곤란하고,First, it is difficult to uniformly adhere to the base sheet in a state in which metal foils having a predetermined width are arranged at regular intervals from each other,
둘째, 특히 일정한 간격을 두고 절개한 금속박띠를 로울러에 감을 때 처음 감아야할 위치를 지정하기가 어려워 결과적으로 금속박띠의 상호 간격이 일정해지지 않으며,Secondly, it is difficult to specify the first position to be wound, especially when winding the metal foil cut off at regular intervals on the roller, and as a result, the mutual gap of the metal foil is not uniform.
셋째, 로울러에 나란하게 감긴 다수의 금속박띠를 풀어가면서 기저시트에 접착시킬 때 좌·우측 금속박띠가 상대적으로 늘어지면서 중간부 금속박띠가 제 위치를 벗어나게 되며 심한 경우 금속박띠가 비틀어지면서 기저시트에 접착되는 문제점이 있었다.Third, when releasing a large number of metal foils wound side by side on the rollers and bonding them to the base sheet, the left and right metal foils are relatively stretched, and the middle metal foils are out of position. There was a problem of being bonded.
이에 본 발명은 상기와 같은 문제점을 해소하기 위해 안출된 것으로,Accordingly, the present invention has been made to solve the above problems,
첫째, 금속박띠가 허용오차 범위내에서 상호 일정한 간격으로 배치되고,First, the metal foils are arranged at regular intervals from each other within the tolerance range,
둘째, 다수의 금속박띠를 로울러에 일정 간격을 유지하면서 손쉽게 감을 수 있으며,Second, it can be easily wound while maintaining a certain distance to the rollers,
셋째, 접착과정에서 다수의 금속박띠가 비틀어지지 않으면서 제 위치에 정확하게 접착되는 금속박 부분코팅 시트의 제조방법을 제공함에 그 목적이 있다.Third, an object of the present invention is to provide a method for manufacturing a metal foil partial coating sheet which is accurately bonded in place without plunging a plurality of metal foils in the bonding process.
상기와 같은 목적을 달성하기 위한 본 발명에 따른 금속박 부분코팅 시트의 제조방법은 금속박을 절개할 때 두 금속박띠 사이의 소정 간격 만큼을 미리 절개하여 버리면서 금속박띠를 감아주고, 금속박띠의 처음부분 및 끝부분을 소정 길이 만큼 절개하지 않고 다수의 금속박띠를 생성하며, 금속박띠에 피복되는 제1금속보호층 및 제2금속보호층의 좌·우 측 두께가 중간측 두께보다 다소 두껍게 되도록 보호층의 부위별 용융온도를 조절하는 것을 그 특징으로 한다.Method for producing a metal foil partial coating sheet according to the present invention for achieving the above object is to cut the metal foil in advance by cutting a predetermined interval between the two metal foil when cutting the metal foil, winding the metal foil, the first part of the metal foil And a plurality of metal foils are formed without cutting the ends by a predetermined length, and the left and right thicknesses of the first metal protective layer and the second metal protective layer coated on the metal foils are somewhat thicker than the intermediate thickness. It is characterized by adjusting the melting temperature for each part.
이하, 본 발명에 따른 금속박 부분코팅 시트의 제조방법의 일 실시예를 첨부된 도면을 기초로 상세히 설명한다.Hereinafter, an embodiment of the method for manufacturing a metal foil partial coating sheet according to the present invention will be described in detail with reference to the accompanying drawings.

금속박적층공정은 투명한 합성수지 필름(1)에 접착제(3)를 도포시켜 휘발성분을 증발시킨 후 알루미늄박과 같은 금속박층(5)은 적층시키는 공정으로, 합성수지 필름(1)과 금속박층(5) 사이에는 용융상태의 제1금속보호층(4)을 흘려보내면서 냉각압연하게 된다. 투명한 합성수지 필름(1)은 칫수안정성, 내열성 및 내구성이 우수한 폴리에스테르 필름이 바람직하며, 필요에 따라 필름(1)의 일측면에 문자나 도형(2)을 인쇄한 경우 문자 인쇄 방향으로 제1접착층(3)을 도포시키는 것이 바람직하다. 제1금속보호층(4)은 유연성과 접착력이 우수한 폴리에틸렌 수지를 사용하는 것이 바람직하며, 통상 310℃~330℃를 유지하여 용융시킨 상태에서 냉각압연기로 흘려보내 압연시키는 데, 좌·우측단의 용융가열온도를 중앙부의 용융가열온도보다 약 10℃ 가량 높게 유지시켜 좌·우측으로 보다 많은 양의 폴리에틸렌수지를 흘려보내는 것이 바람직하다.In the metal foil lamination process, an adhesive 3 is applied to a transparent synthetic resin film 1 to evaporate volatile components, and then a metal foil layer 5 such as aluminum foil is laminated. The synthetic resin film 1 and the metal foil layer 5 are laminated. Cold rolling is carried out while flowing the first metal protective layer 4 in a molten state therebetween. The transparent synthetic resin film 1 is preferably a polyester film having excellent dimensional stability, heat resistance and durability, and, if necessary, the first adhesive layer in the direction of text printing when letters or figures 2 are printed on one side of the film 1. It is preferable to apply (3). The first metal protective layer 4 is preferably a polyethylene resin having excellent flexibility and adhesive strength, and is usually flowed into a cold rolling mill in a molten state maintained at 310 ° C. to 330 ° C. to be rolled. It is preferable to keep the melt heating temperature about 10 ° C. higher than the melt heating temperature at the center to flow more polyethylene resin to the left and right sides.
금속박피복공정은 합성수지필름(1)이 적층되지 않은 금속박층(5)의 다른 면을 제2금속보호층(7)으로 피복시키는 공정으로, 금속박적층공정이 끝난 금속박층(5)위에 제2접착층(6)을 도포시킨 후, 용융상태의 제2금속보호층(7)을 냉각압연 피복하게 된다. 제2금속보호층(7) 역시 제1금속보호층(4)과 같은 폴리에틸렌 수지를 사용하는 것이 바람직하며, 좌·우측단의 용융가열온도를 중앙부의 용융가열온도보다 약 10℃ 가량 높게 유지시키는 것이 바람직하다.The metal thin coating process is to cover the other side of the metal foil layer 5, on which the synthetic resin film 1 is not laminated, with the second metal protective layer 7, and the second adhesive layer on the metal foil layer 5 after the metal foil lamination process is completed. After applying (6), the second metal protective layer 7 in the molten state is subjected to cold rolling coating. Preferably, the second metal protective layer 7 also uses the same polyethylene resin as the first metal protective layer 4, and maintains the melt heating temperature at the left and right ends about 10 DEG C higher than the melt heating temperature at the center. It is preferable.
금속박절개공정은 상기 피복금속박(10)을 상호 소정 간격(G) 만큼 떨어진 다수의 금속박띠(11a)(11b)로 절개시키는 공정으로, 절개되어 생산되는 상당 길이의 금속박띠(11a)(11b)를 로울러에 원활하게 감기 위해서는 금속박(10)의 처음 부분 및 끝 부분을 일정 길이(L) 만큼 절개하지 않고 중간부분만을 상호 소정 간격(G)을 유지하도록 절개하여 감아야 한다.The metal foil cutting process is a process of cutting the coated metal foil 10 into a plurality of metal foil bands 11a and 11b spaced apart from each other by a predetermined distance G. The metal foil bands 11a and 11b of a considerable length that are cut and produced are cut. In order to smoothly wound on the rollers, the first part and the end part of the metal foil 10 should be cut and wound so as to maintain a predetermined distance G from each other without cutting the predetermined length L.
금속박띠접합공정은 동일 평면상에서 상호 일정 간격(G)을 유지하고 있는 다수의 금속박띠(11a)(11b)를 기저시트(9)에 압연접합시키는 공정으로, 금속박띠(11a)(11b)와 기저시트(9) 사이에는 용융상태의 접합층(8)이 흘러내리도록 하고 이를 냉각시키면서 금속박띠(11a)(11b)와 기저시트(9)를 압연접합시키게 된다. 기저시트(9)는 합성수지사를 교차직조시킨 후 그 표면에 폴리에틸렌을 얇게 피복하여 습기와 공기가 통과하지 못하게 한 우븐클로스(woven cloth)가 바람직하며, 접합층(8)은 폴리에틸렌과 같은 열가소성수지가 적합하다. 기저시트(9)는 그 두께에 비해 인장강도가 충분히 커서 가늘고 길게 형성되더라도 쉽게 늘어지지 않아야 한다.The metal foil joining process is a process of rolling-bonding a plurality of metal foils 11a and 11b on the same plane to the base sheet 9, and the metal foils 11a and 11b. The metal sheet 11a, 11b and the base sheet 9 are roll-bonded while the bonding layer 8 in a molten state flows down between the base sheets 9 and cools it. The base sheet 9 is preferably a woven cloth that cross-weaves the synthetic resin yarn and then covers the surface with a thin polyethylene to prevent moisture and air from passing through, and the bonding layer 8 is a thermoplastic resin such as polyethylene. Is suitable. The base sheet 9 should not easily sag even if it is formed long and thin because its tensile strength is large enough for its thickness.
기저시트절개공정은 기저시트(9)상에서 금속박띠(11a)(11b)가 접합되지 않은 부분을 절개선(12)을 따라 절개하여 기저시트(9)의 중앙부에 금속박띠(11a)(11b)가 배치·접합된 금속박 부분코팅시트를 생산하는 공정이다.In the base sheet cutting process, a portion of the base sheet 9 which is not bonded to the metal foil strips 11a and 11b is cut along the cut line 12, and the metal foil strips 11a and 11b are formed at the center of the base sheet 9. Is a process of producing a metal foil partial coated sheet placed and bonded.
상기와 같은 공정으로 된 본 발명의 작용 및 효과를 상세히 설명한다.The operation and effect of the present invention in the above process will be described in detail.
본 발명에 따른 금속박 부분코팅시트의 제조방법에 따라 피복금속박(10)을 절개하여 미리 소정 간격(G)을 갖는 다수의 금속박띠(11a)(11b)를 생산하고 그 간격(G)을 유지한 상태에서 기저시트(9)상에 접합시키면 금속박띠(11a)(11b)가 기저시트(9)상 소정 위치에 정확하게 접합되게 되며, 아울러 다수의 금속박띠(11a)(11b)가 처음부분 및 끝부분에서 소정 길이(L) 만큼 서로 연결되어 있으므로 금속박띠(11a)(11b) 사이의 간격(G)을 유지시키기가 용이하여 접합작업에 걸리는 시간 및 노력을 단축시킬 수 있다.According to the manufacturing method of the metal foil partial coating sheet according to the present invention by cutting the coated metal foil 10 to produce a plurality of metal foil (11a) (11b) having a predetermined interval (G) in advance and maintaining the gap (G) In the state of bonding to the base sheet 9, the metal foil strips 11a and 11b are precisely bonded to a predetermined position on the base sheet 9, and a plurality of metal foil strips 11a and 11b are at the beginning and end. Since the portion is connected to each other by a predetermined length (L), it is easy to maintain the gap (G) between the metal foil (11a) (11b) can reduce the time and effort required for the bonding operation.
또한, 좌·우측에 위치한 금속박띠(11a)의 두께가 중간부에 위치한 금속박띠(11b)의 두께보다 다소 두껍게 형성되므로 다수의 금속박띠(11a)(11b)와 기저시트(9)를 압연접합시킬 때 압연로울러에 의해 좌·우측 금속박띠(11a)가 길이방향으로 긴장되면서 중간부의 금속박띠(11b)도 비틀림이나 늘어짐 없이 서로 일정 간격(G)을 유지하면서 평행하게 접합되는 것이다.In addition, since the thickness of the metal foil strips 11a positioned on the left and right sides is formed to be somewhat thicker than the thickness of the metal foil strips 11b positioned on the middle portion, the plurality of metal foil strips 11a and 11b and the base sheet 9 are roll-bonded. When the left and right metal foil bands 11a are tensioned in the longitudinal direction by the rolling rollers, the metal foil bands 11b in the middle part are also joined in parallel while maintaining a constant distance G from each other without twisting or sagging.
상기와 같이 생산된 금속박 부분 코팅시트는 금속박(5)을 폴리에틸렌과 폴리에스테르와 같은 열가소성 수지로 피복시킨 형태로 생산되므로 습기와 공기를 차단시켜 금속박(5)의 산화를 미연에 방지할 수 있고, 금속박(5)에 의해 빛을 차단시킬 수도 있어서 자외선과 습기를 동시에 차단시키기 위한 포장지로 사용될 수 있다. 또한, 금속박층(5)이 금속탐지기에 의해 쉽게 탐지되므로 지중선로나 수도관과 함께 금속박 부분 코팅시트를 매설하게 되면 굳이 굴착작업을 거치지 않고 지하매몰물의 위치를 정확하게 파악할 수도 있다. 일정한 내용이 담긴 문자(2)를 합성수지 필름(1)에 인쇄하여 제품의 광고·선전 효과를 배가시킬 수도 있는 것이다.The metal foil partial coating sheet produced as described above is produced in a form in which the metal foil 5 is coated with a thermoplastic resin such as polyethylene and polyester, thereby preventing moisture and air to prevent oxidation of the metal foil 5 in advance, Light may be blocked by the metal foil 5, and thus may be used as a wrapping paper for simultaneously blocking ultraviolet rays and moisture. In addition, since the metal foil layer 5 is easily detected by the metal detector, when the metal foil partial coating sheet is embedded together with the underground line or the water pipe, the location of the underground buried material may be accurately determined without going through the excavation work. It is also possible to double the advertising and propagation effect of the product by printing the characters 2 containing certain contents on the synthetic film 1.
