본 발명은 폴리에칠렌(PE)으로 된 발포시이트와 표면에 다양한 무늬가 그라비아 인쇄된 폴리에칠렌 필름(이하 PE필름이라 칭함)을 효과적으로 열융착시켜서 다양한 용도의 원단으로 사용할 수 있도록 한 보온방습용 시이트지의 제조방법에 관한 것이다.The present invention is a method of manufacturing a sheet of thermal-moisture-proof sheet which can be used as a fabric of various applications by effectively heat-sealing a foam sheet made of polyethylene (PE) and a gravure printed polystyrene film (hereinafter referred to as PE film) on the surface thereof. It is about.

일반적으로 폴리에칠렌(PE)의 재질로 된 발포시이트와 PE필름은 다같이 열에 매우 약하기 때문에 통상의 열융착 방식으로는 상기한 발포시이트와 PE필름을 효과적으로 열융착시킬 수가 없다.In general, since the foam sheet and the PE film made of polyethylene (PE) are very weak to heat together, the foam sheet and the PE film cannot be thermally fused effectively by the conventional thermal fusion method.

즉, 통상의 열융착 방식은 롤 형태로 감겨있는 표면지와 이면지를 가이드 로울러에 의해 서로 겹쳐지도록 한 후 그 겹쳐진 표면지와 이면지의 양면을, 또는 어느 일면만을 가열로울러가 일정온도로 가열시키면서 압착토록 하여 열융착시키도록 되어 있다.That is, in the conventional heat fusion method, the surface paper and the back paper wound in the form of a roll are overlapped with each other by the guide rollers, and then both sides of the overlapped surface paper and the back paper are pressed or heated on one surface only by heating rollers to a predetermined temperature. It is intended to be thermally fused.

그런데 상기한 플리에칠렌 재질의 발포시이트와 PE필름은 겹쳐진 상태에서의 양 표면이나 일면을 가열로울러로 가열 압착할 경우 가열로울러의 뜨거운 열이 겹쳐진 발포시이트와 PE필름의 외표면에 먼저 전달된 후 내면에 전달되기 때문에 가열로울러의 온도를 낮게 할 경우에는 융착이 잘 안되고, 반대로 온도를 높게 할 경우에는 발포시이트와 PE필름의 내면이 원활히 융착될 수 있을 정도로 녹기도 전에 발포시이트와 PE필름의However, when the foam sheet and PE film of the above-mentioned ethylene foam is heat-compressed on both surfaces or one surface of the overlapped state with a heating roller, the hot heat of the heating roller is first transferred to the outer surface of the foam sheet and the PE film, which are overlapped, and then the inner surface. When the temperature of the heating roller is lowered, the fusion is not good. On the contrary, when the temperature of the heating roller is lowered, the foamed sheet and the PE film may not be melted enough to melt the inner surface of the foamed sheet and the PE film smoothly.

외주면이 먼저 녹아 버리게 되어 열융착시킬 수가 없었다.The outer circumferential surface melted first and could not be thermally fused.

특히 PE필름의 표면에 다양한 무늬가 인쇄되어 있는 것일 경우에는 그 인쇄된 PE필름의 표면을 가열로울러가 가열 압착하는 과정을 거치는 동안 인쇄된 무늬가 가열로울러에 눌러 붙는 등의 폐단이 있어서 제품의 질이 떨어지게 되는 문제점이 있으며, 이로 인해 표면에 다양한 무늬가 그라비아 인쇄되어 있는 PE필름과 발포시이트를 열융착한 보온방습용 시이트지의 제공이 현재까지 이루어지지 못하였다.In particular, when various patterns are printed on the surface of the PE film, the printed pattern is stuck to the heating roller while the roller is heated and pressed to the surface of the printed PE film. There is a problem that fall, and thus the provision of a thermal insulation and moisture-proof sheet of heat-sealed PE film and the foam sheet which is printed gravure on the surface has not been made until now.

본 발명은 상기와 같은 점을 감안하여 PE필름의 표면에 인쇄되어 있는 다양한 무늬를 전혀 손상함이 없이 발포시이트와 효과적으로 융착시킨 보온방습용 시이트지를 제공함과 아울러 동 시이트지의 제조방법 및 제조장치를 제공하는데 그 목적이 있는 것으로서 이를 첨부된 실시예 도면에 의해 상세히 설명하면 다음과 같다.In view of the above, the present invention provides a heat- and moisture-proof sheet paper which is effectively fused with a foamed sheet without damaging various patterns printed on the surface of a PE film, and also provides a method and a manufacturing apparatus of the sheet. The purpose of this is as described in detail by the accompanying embodiment drawings as follows.

본 발명의 보본방습용 시이트지(1)는 표면에 다양한 무늬가 인쇄된 PE필름(2)의 이면에 발포시이트(3)를 엠보싱 된 홈(4)과 돌기(5)가 형성되게 열융착하여 된 것이다.The moisture-proof sheet paper 1 of the present invention is heat-sealed so that the grooves 4 and the projections 5 embossed with the foam sheet 3 are formed on the back surface of the PE film 2 with various patterns printed on the surface thereof. It is.

그리고 상기한 시이트지(1)의 제조장치로는 일실시예로서 다양한 무늬가 인쇄된 롤형의 PE필름(2)과 역시 롤형의 발포시이트(3)를 각각의 가이드 로울러(22)(23)에 의해 일정간격으로 떨어진 상태에시 외주면이 엠보싱 금형으로 형성된 성형로울러(24)와 받침로울러(25) 사이로 통과되게 하고, 떨어져 있는 PE필름(2)과 발포시이트(3)의 내면 적당한 위치에는 PE될롬(2)과 발포시이트(3)의 대향된 내면으로 열풍을 분사하는 히팅팬(30)을 설치하여 된 것으로서 이때 히팅팬(30)은 가스나 전기틀 사용하는 것이 적합하며, 성형로울러(2)의 내부에는 냉각수가 순환되고 있어 성형과 동시에 소재를 냉각시켜 주는 기능을 갖고 있다.In addition, the apparatus for manufacturing the sheet 1 includes, as an example, a roll-shaped PE film 2 and a roll-shaped foam sheet 3, which have various patterns printed thereon, on each of the guide rollers 22, 23. When the outer circumferential surface is separated by a certain interval by the embossed mold, the outer roller is passed between the forming roller 24 and the support roller 25, and the PE film (2) and the PE sheet (3) in the proper position on the inner surface of the separated PE film (2) (2) and the heating fan 30 to inject hot air to the opposite inner surface of the foam sheet (3), wherein the heating fan 30 is suitable to use gas or electric frame, forming roller (2) The cooling water is circulated in the interior thereof, and has a function of cooling the material simultaneously with molding.

상기한 본 발명의 장치에 의해 보온방습용 시이트지(1)를 제조하는 과정을 설명하면 다음과 같다.Referring to the process of manufacturing the sheet for thermal insulation moisture-proof (1) by the apparatus of the present invention described above is as follows.

제1도에서와 같이 가이드 롤러(22)(23)에 의해 PE필름(2)과 발포시이트(3)가 일정간져으로 벌어진 상태에서 성형로울러(24)와 받침로울러(25) 사이로 진입될 때 대향된 PE필름(2)과 발포시이트(3) 사이에 설치된 히팅팬(30)에 의해 양쪽으로 70∼120℃의 열을 가하여 준다.As shown in FIG. 1, when the PE film 2 and the foamed sheet 3 are separated by the guide rollers 22 and 23 in a state of being spaced apart at regular intervals, they face each other when they enter between the forming roller 24 and the support roller 25. Heat of 70 to 120 ° C. is applied to both sides by the heating fan 30 provided between the PE film 2 and the foam sheet 3.

이와 같이 PE필름(2)과 발포시이트(3)의 사이에는 열을 가하면 PE필름(2)과 발포시이트(3)는 양면중에서 열을 직접받는 내면들이 간접열을 받는 외면보다 빨리 열을 받아 내면들이 약간 녹게 되며, 이러한 상태에서 PE필름(2)과 발포시이트(3)가 서로 겹쳐지도록 성형로울러(24)와 받침로울러(25) 사이로 통과시켜 압착시킨다.Thus, when heat is applied between the PE film 2 and the foam sheet 3, the PE film 2 and the foam sheet 3 receive heat faster than the outer surface which receives indirect heat. They are slightly melted, and in this state, the PE film 2 and the foamed sheet 3 pass between the forming roller 24 and the support roller 25 so as to overlap each other, and then compressed.

그러면 외주면에 엠보싱 금형으로 형성된 성형로울러(24)는 PE필름(2)의 외면을 눌러주고, 받침로울러(25)는 발포시이트(3)의 외면을 눌러 압착하게 되는데, 이때 성형로울러(24)와 닿게 되는 PE필륨(2)은 성형로울러(24)의 엠보싱된 외주면에 의해 제2도에서와 같이 홈(4)가 돌기(5)가 형성되면서 내면이 직접열을 받아 녹아있는 상태인 발포시이트(3)와 융착이 된다.Then, the forming roller 24 formed by the embossing mold on the outer circumferential surface presses the outer surface of the PE film 2, and the support roller 25 presses the outer surface of the foam sheet 3 to press the molded roller 24. The PE sheet (2) to be contacted is a foamed sheet in which the inner surface is melted by direct heat while the protrusion 4 is formed by the embossed outer circumferential surface of the forming roller 24 as shown in FIG. 3) and fusion.

그리고 위와 같이 성형로울러(24)와 받침로울러(25)에 의해 PE필름(2)이 엠보싱 처리되면서 발포시이트(3)와 열융착될 때 성형로울러(24) 속에는 냉각수가 순환되고 있으므로 히팅팬(30)으로 열을 받아 내면들이 녹아있던 PE필름(2)과 발포시이트(3)는 엠보싱되면서 압착되어 서로 달라불는 순간 즉시 냉각 처리되므로 융착된 상태가 매우 견고 양호하게 되는 것이다.Since the PE film 2 is embossed by the forming roller 24 and the support roller 25 as described above, the cooling water is circulated in the forming roller 24 when the PE film 2 is heat-sealed with the foam sheet 3. PE film (2) and the foam sheet (3), the inner surface is melted by the heat is compressed by embossing and immediately cooled to the other, so that the welded state is very firm and good.

상기와 같이 제조되는 본 발명의 시이트지(1)는 저면에 용착되는 발포시이트(3)가 완충력과 보온력 등을 갖고 있고, 표면에 융착되는 PE필름(2)은 방습 및 방수기능을 갖고 있으므로 찬장, 싱크대, 옷장 등의 선반이나 서랍의 바닥에 까는 시트로 적합한 것이며, 그 외에도 야외용 매트나 양변기용 좌판 및 덮개의 커버 등을 만들때 그 표면 원단으로 사용할 경우 촉감이 좋고 보온 및 방습, 방수의 효과가 뛰어난 효과가 있다.Sheet paper 1 of the present invention manufactured as described above is a cupboard because the foam sheet (3) to be welded to the bottom surface has a buffering force and a thermal insulation, and the PE film (2) fused to the surface has a moisture-proof and waterproof function It is suitable as a sheet to the floor of a shelf or a drawer of a sink, a wardrobe, a wardrobe, etc. In addition, when making an outdoor mat, a toilet seat cover, and a cover of a cover, the surface fabric is used to make it feel good, and it has the effect of keeping warm, moistureproof, and waterproof. Has an excellent effect.

또한 본 발명은 PE필름(2)을 열처리 할 때 또는 성형로울러(24)로 엠보싱 성형 압착할 때 다양한 무늬가 인쇄되어 있는 외표면을 가열하지 않고 발포시이트(3)와 접면되는 내면을 성형로울러(24)가 아닌 히팅팬(30)으로 미리 가열하는 방식이기 때문에 종래와 같이 PE필름의 외표면에 인쇄된 무늬가 열처리에 의해 또는 성형로울러에 의해 손상될 우려가 전혀 없는 것이므로 상품가치를 최대한 높힐 수가 있는 매우 유용한 발명이다.In addition, the present invention, when the heat treatment of the PE film (2) or when pressing the embossing molding by the molding roller 24, the inner surface in contact with the foam sheet (3) without heating the outer surface on which the various patterns are printed forming roller ( Since the heating fan 30 is not heated in advance, the printed pattern on the outer surface of the PE film is not likely to be damaged by heat treatment or molding rollers. That is a very useful invention.
