Description

저온합지시트제조방법과 장치 및 이를 이용한 저온합지시트{Method and apparatus for making a sheet adhered with an adhesive and a laminate using the same}TECHNICAL FIELD [0001] The present invention relates to a method and an apparatus for manufacturing a low temperature composite sheet, and a low temperature composite sheet using the same.

본 발명은 주로 압출시트지에 필름이 합지 되도록 하는 합지시트에 관한 것으로서, 더욱 상세하게는 저온으로 합지 되도록 하여 불량율 감소가 도모되고, 불량 발생된 합지시트를 재활용할 수 있도록 개선된 저온합지시트제조방법과 장치 및 이를 이용한 저온합지시트에 관한 것이다.The present invention relates generally to a laminated sheet in which a film is laminated on an extruded sheet, and more particularly, to an improved low-temperature laminated sheet manufacturing method capable of reducing a defective ratio by causing lamination at a low temperature and recycling a defective laminated sheet And a low-temperature laminated sheet using the same.

일반적으로 2개 이상의 시트지나 필름을 합지되게 하는데 있어서 크게 구분하면 각각 제조된 필름을 선행기술문헌의 특허문헌에 기재된 선행기술과 같이 서로 포개지게 하고 고온으로 가열 및 가압하여 상호 융착되게 하여 합지되게 하는 것이 있고, 다른 하나는 압출기의 압출다이에서 압출되는 시트지에 다른 필름이 포개지게 하여 고온 상태로 압출되는 젤 상태의 시트지에 필름이 융착되게 하는 제조 방법이 알려져 있다. 본 발명에서 이해를 돕기 위해 상기와 같이 압출기의 압출다이에서 압출되는 시트지를 압출시트지라고 명칭하고 설명하는 것으로 한다.Generally, two or more sheets or films are largely divided into laminated films. The laminated films are made to overlap each other as in the prior art described in the patent documents of the prior art documents, heated and pressed at a high temperature, And the other is a manufacturing method in which a film is extruded from an extrusion die of an extruder and another film is superimposed on the sheet to cause the film to be fused to a sheet of gel state extruded at a high temperature. In order to facilitate understanding of the present invention, the sheet to be extruded in the extrusion die of the extruder will be referred to as an extruded sheet.

따라서, 상기한 선행기술들은 시트지나 또는 필름이 고온으로 가열된 상태에서 재질 자체가 녹아서 융착 되게 합지 되는 것이기 때문에 두개 이상의 시트지나 필름이 일체가 되는 상태로 합지 되는 것이다.Therefore, the above-described prior arts are such that two or more sheets or films are joined together in a state in which the sheet itself or the film is heated to a high temperature so that the material itself is melted and fused.

그러므로 종래에는 합지 과정에 여러 가지 이유에 의해서 불량이 발생 되면 이종 시트지나 필름의 경우 서로 박리시킬 수 없게 되는 문제점이 있고, 그로 인해 재활용이 불가능하고 전부 폐기해야 하는 비경제적인 문제점이 야기 되었다.Therefore, conventionally, when defects are caused by various reasons in the lapping process, in the case of a heterogeneous sheet or film, there is a problem that they can not be peeled off from each other, and therefore, there is an uneconomical problem in that it can not be recycled and must be completely discarded.

특히, 압출시트지에 필름이 융착되어 합지되는 경우에는 압출다이에서 압출되는 압출시트지가 고온상태이기 때문에 탄화물이 발생되는 경우가 많고, 이러한 탄화물이 있는 압출시트지에 필름이 융착되므로 불순물이 있는 상태로 합지되어 불량이 발생되는 문제점이 있다. Particularly, when the film is fused to the extruded sheet, the extruded sheet extruded from the extruded die is in a high temperature condition, so that carbide is often generated. Since the film is fused to the extruded sheet having such a carbide, Thereby causing defects.

그러므로 조절실린더(38)에 의해서 냉각로울러(30)가 이동되어 가압로울러(20)와의 이격 된 간격을 크게 또는 작게 조절할 수 있게 되고, 그로 인해 접착제(2)가 도포된 압출시트지(1) 두께에 따라 가압로울러(20)와 냉각로울러(30)의 간격을 조절하게 되는 것이다.Therefore, the cooling roller 30 can be moved by the adjusting cylinder 38 to adjust the spacing between the pressing roller 20 and the pressing roller 20 to be large or small so that the thickness of the extruded sheet 1 coated with the adhesive 2 The distance between the pressurizing roller 20 and the cooling roller 30 is adjusted.

본 발명은 압출다이(10)에서 압출되는 압출시트지(1) 상면부에 PP혼합접착제(2)가 도포된 상태에서 도 1에 나타낸 바와 같이 가압로울러(20)와 냉각로울러(30) 사이를 통과하게 됨으로써 PP혼합접착제(2)가 냉각되는 상태가 된다.The present invention is characterized in that the PP mixed adhesive 2 is applied on the upper face of the extruded sheet 1 to be extruded in the extrusion die 10 and passes through between the pressurizing roller 20 and the cooling roller 30 So that the PP mixed adhesive 2 is cooled.

압출시트지(1)는 압출기(H)에서 녹아서 압출될 수 있는 수지재질의 압출시트지(1)로서, 주로 1mm 이하의 두께를 갖는 것이 압출되고, PP혼합접착제(2)는 그 보다 얇은 두께를 갖게 된다.The extruded sheet 1 is an extruded sheet 1 made of a resin material which can be melted and extruded in an extruder H and is mainly extruded to have a thickness of 1 mm or less and the PP mixed adhesive 2 has a thickness do.

그러므로 PP혼합접착제(2)에 냉각로울러(30)가 접촉되면 PP혼합접착제(2)가 냉각되는 상태가 되므로 냉각로울러(30)를 통과한 상태에서는 젤 상태와 같은 상태가 된다.Therefore, when the cooling roller 30 is brought into contact with the PP mixed adhesive 2, the PP mixed adhesive 2 is in a state of being cooled, and therefore, the state is the same as that of the gel state when passing through the cooling roller 30.

따라서, 본 발명은 가압로울러(20)와 상대적으로 배치되는 가압로울러(40) 사이로 저온상태로 냉각된 PP혼합접착제(2)가 있는 압출시트지(1)와 이종시트지(3)가 겹치도록 통과되게 하여 PP혼합접착제(2)에 이종시트지(3)가 가압되어 접착되도록 구성된다. Therefore, the present invention is characterized in that the extruded sheet 1 having the PP mixed adhesive 2 cooled to a low temperature state between the pressurizing rollers 40 disposed relatively to the pressurizing roller 20 is passed through the overlapped sheet 3 in an overlapping manner So that the dissimilar sheet 3 is pressed and adhered to the PP mixed adhesive 2.

상기 이종시트지(3)는 필름이나 부직포일 수 있는 것으로서, 이종시트지롤(3a)에서 풀림되어 한쌍의 가압로울러(20,40) 사이로 끼워져 들어가면서 저온상태로 냉각된 PP혼합접착제(2)에 접착되는 상태가 됨에 따라 압출시트지(1)와 이종시트지(3)가 접착된 상태의 저온합지시트(123)가 제조되는 것이다. 부호 R은 가이드롤러이고, 부호 123a는 합지시트롤을 나타낸다.The dissimilar sheet 3 may be a film or a nonwoven fabric. The dissimilar sheet 3 may be a film or a nonwoven fabric. The dissimilar sheet 3 may be a film or a nonwoven fabric. The dissimilar sheet 3 is bonded to a PP mixed adhesive 2, The state that the extrusion sheet 1 and the heterogeneous sheet 3 are adhered to each other is produced. Reference symbol R denotes a guide roller, and reference numeral 123a denotes a trolley upon jointing.

즉, 본 발명은 압출다이(10)에서 압출시트지(1)가 압출되는 과정에 PP혼합접착액(2a)이 도포되어 압출되고, 그 이후에 냉각로울러(30)에 의해서 PP혼합접착액(2a)이 압출온도와 상대적으로 낮은 저온으로 냉각되게 하여 젤 상태의 저온 상태의 PP혼합접착제(2)가 형성되게 하고, 저온 상태의 PP혼합접착제(2)가 피착된 압출시트지(1)와 이종시트지(3)가 겹치도록 한쌍의 가압로울러(20,40) 사이를 통과되게 하여 저온 상태의 PP혼합접착제(2)에 이종시트지(3)가 가압되게 접착되어 하나의 저온합지시트(123)가 제조되는 것에 특징이 있는 것이다.That is, in the present invention, the PP mixed adhesive liquid 2a is applied and extruded in the process of extruding the extruded sheet 1 in the extruding die 10, and thereafter the PP mixed adhesive liquid 2a Is cooled to a low temperature relatively lower than the extrusion temperature to form a gel-state low-temperature PP mixed adhesive (2), and the extruded sheet (1) coated with the low-temperature PP mixed adhesive (2) The different kind of sheet 3 is pressed and adhered to the low-temperature PP mixed adhesive 2 so as to pass between the pair of pressure rollers 20 and 40 so as to overlap with each other, It is characterized by becoming.

한편, 압출온도와 상대적으로 낮은 저온으로 PP혼합접착제(2)를 냉각시켜서 이종시트지(3)가 접착되게 한 것이므로 저온상태의 PP혼합접착제(2)에 의해 합지되었다는 의미이므로 이해를 돕기 위해서 본 발명에서 얻어지는 합지를 저온합지시트(123)라고 명칭 하는 것으로 하고 설명되었다.On the other hand, since the PP mixed adhesive 2 is cooled at a low temperature relatively lower than the extrusion temperature to bond the different sheet 3, it means that the PP mixed adhesive 2 is laminated at a low temperature. Is referred to as a low-temperature laminated sheet 123. The low-

PP혼합접착제(2)의 성분혼합비율을 조절하면서 1mm 두께의 압출시트지(1)로서 PP시트지가 압출되게 하되 압출다이(10)의 압출온도 260℃로 압출하면서 PP혼합접착액(2a)을 냉각로울러(30)에 의해 압출온도와 상대적으로 저온 상태가 되도록 냉각시켜 저온 상태의 PP혼합접착제(2)가 되게 하여 이종시트지(3)로서 0.5mm 두께의 PP필름이 접착되게 하는 실험을 실시하였고, 또한 이들을 상호 분리되게 하는 실험을 [표 1]과 같이 실시하였다.The PP mixed adhesive liquid 2a was cooled while extruding the PP sheet as the extruded sheet 1 having a thickness of 1 mm while controlling the component mixing ratio of the PP mixed adhesive 2, The rollers 30 were cooled so as to be in a relatively low temperature state relative to the extrusion temperature to make the PP mixed adhesive 2 in the low temperature state to adhere the PP film having a thickness of 0.5 mm as the different sheet 3, Experiments to separate them were carried out as in [Table 1].

상기 [표 1]에 의하면 PP혼합접착제(2)는 폴리프로필렌 40~45중량%, 본드 55~60중량%가 혼합되어 이루어진 것이 접착성도 양호하고 접착된 압출시트지(1)와 이종시트지(3)를 서로 분리하는데 용이한 것으로 나타났으며, PP혼합접착제(2)를 110~120℃로 냉각시켜서 이종시트지(3)가 접착되게 하는 것이 양호한 것으로 나타났다.According to the above Table 1, the PP mixed adhesive 2 is formed by mixing 40 to 45% by weight of polypropylene and 55 to 60% by weight of a bond. The result is that the extruded sheet 1 and the heterogeneous sheet 3, And it was found that it was preferable to cool the PP mixed adhesive 2 to 110 to 120 ° C to bond the heterogeneous sheet 3 to each other.

한편, 본 발명은 도 6에 나타낸 바와 같이 접착액두께조절부재(151)에 냉각수로(158)를 구비하도록 실시될 수 있다.6, the present invention can be implemented to include a cooling water path 158 in the adhesive liquid thickness control member 151. [

이 경우 압출다이(10)의 다른 구성은 이미 [실시예 1]와 동일한 것이므로 여기서의 상세한 설명은 생략하는 것으로 한다.In this case, the other structure of the extrusion die 10 is the same as that of the first embodiment, and a detailed description thereof will be omitted.

상기 냉각수로(158)은 냉각유니트(미도시됨)와 연결되는 것이므로 냉각수(W)가 순환되는 것이다.Since the cooling water path 158 is connected to a cooling unit (not shown), the cooling water W circulates.

따라서, 본 발명은 PP혼합접착액토출로(152)를 따라 토출되는 PP혼합접착액(2a)을 냉각시키게 되므로 압출시트지(1)에 도포되어 압출되는 PP혼합접착액(2a)을 더욱 신속하게 냉각시킬 수 있게 된다.Therefore, the present invention cools the PP mixed adhesive liquid 2a ejected along the PP mixed adhesive liquid ejection path 152, so that the PP mixed adhesive liquid 2a applied to the extruded sheet 1 and extruded can be ejected more rapidly Thereby allowing cooling.

그리고 도 7에 나타낸 바와 같이 PP혼합접착제(2)가 피착된 압출시트지(1)가 또 다시 냉각로울러(30)와 가압로울러(20) 사이를 통과되게 하여 2차적으로 PP혼합접착제(2)의 냉각작용이 도모되게 할 수 있다.7, the extruded sheet 1 on which the PP mixed adhesive 2 is adhered is again passed between the cooling roller 30 and the pressurizing roller 20, So that the cooling action can be promoted.

또한, 경우에 따라서는 PP혼합접착제(2)가 피착된 압출시트지(1)가 또 다시 냉각로울러(30)와 냉각로울러(30) 사이를 통과되게 하여 2차적으로 PP혼합접착제(2)의 냉각작용이 도모되게 할 수도 있는 것으로서, 더욱 확실한 PP혼합접착제(2) 냉각 작용이 도모되도록 할 수 있고, PP혼합접착제(2)가 냉각되는 온도를 정확성 있게 냉각시킬 수 있게 된다.In some cases, the extruded sheet 1 on which the PP mixed adhesive 2 is adhered is again passed between the cooling rollers 30 and the cooling rollers 30 to cool the PP mixed adhesive 2 As a result, the more reliable function of cooling the PP mixed adhesive 2 can be achieved, and the temperature at which the PP mixed adhesive 2 is cooled can be cooled accurately.

물론, 도 7에 나타낸 실시상태는 접착액두께조절부재(151)에 냉각수로(158)를 구비하지 않는 상태에서도 실시 가능하다.Of course, the embodiment shown in Fig. 7 can be implemented without providing the cooling water passage 158 in the adhesive liquid thickness adjusting member 151. Fig.

또한, 본 발명은 도 8에 나타낸 바와 같이 PP혼합접착제(2)가 피착된 압출시트지(1)가 한쌍의 냉각로울러(30) 사이를 통과되게 하여 PP혼합접착제(2)의 냉각작용이 이루어지게 한 후에 이종시트지(3)가 끼워지게 통과하게 되는 로울러도 냉각로울러(30)로 이루어지게 함으로써 더욱 효율적인 냉각 작용과 가압작용이 동시에 이루어지게 할 수도 있는 것이다.8, the extruded sheet 1 on which the PP mixed adhesive 2 is adhered is allowed to pass between the pair of cooling rollers 30 so that the cooling action of the PP mixed adhesive 2 is performed And the cooling rollers 30 that pass through the different kind of sheet paper 3 after they are passed through the cooling rollers 30 can be made to perform the cooling operation and the pressing action more efficiently at the same time.

본 발명에 실시되는 냉각로울러(30)는 도 9에 나타낸 바와 같이 외주면에 다수의 미세요홈부(30a)와 미세돌기부(30b)를 갖도록 실시될 수 있다.The cooling roller 30 according to the present invention can be implemented to have a plurality of fine groove portions 30a and fine protrusions 30b on the outer circumferential surface as shown in FIG.

이 경우에는 냉각로울러(30)에 의해서 PP혼합접착제(2)가 냉각되는 동시에 그 PP혼합접착제(2) 표면에 도 10의 (a)에 나타낸 바와 같이 요홈부(2b) 및 요철부(2c)가 형성되는 상태가 된다.In this case, the PP mixed adhesive 2 is cooled by the cooling roller 30 and the recessed portion 2b and the recessed portion 2c are formed on the surface of the PP mixed adhesive 2 as shown in Fig. 10 (a) Is formed.

그러므로 이종시트지(3)가 가압로울러(40)에 의해 PP혼합접착제(2) 표면에 가압되는 상태가 되면 도 10의 (b)에 나타낸 바와 같이 요철부(2c)가 눌리게 되면서 양 옆방향으로 퍼지게 되면서 이종시트지(3)가 접착되는 상태가 되고, 그로 인해 이종시트지(3)와 PP혼합접착제(2) 사이에는 매우 작은 공간 상태의 요홈부(2b)가 존재하는 상태가 된다.Therefore, when the sheet 3 of different kind is pressed by the pressure roller 40 to the surface of the PP mixed adhesive 2, as shown in Fig. 10 (b), the recessed / concave portions 2c are pressed, So that the heterogeneous sheet 3 is adhered to the adhesive layer 3 and the space 2b having a very small space is present between the dissimilar sheet 3 and the PP mixed adhesive 2. As a result,

그러므로 압출시트지(1)와 이종시트지(3)를 분리시킬 때에는 요홈부(2b) 부분이 접착되지 않은 상태이므로 접착면적이 적어서 보다 수월하게 분리시킬 수 있게 되는 것이다.Therefore, when separating the extruded sheet 1 and the dissimilar sheet 3 from each other, the portion of the recessed portion 2b is not adhered, so that the adhesive area is small and it can be separated more easily.

본 발명의 이해를 돕기 위해 접착제에 의해서만으로 접착되게 할 시에는 접착강도가 높아서 압출시트지(1)와 이종시트지(3)를 분리시킬 수 없거나 매우 어려우나, 본 발명은 PP혼합접착제(2)의 PP성분의 접착력이 비교적 낮으므로 이종시트지(3)를 압출시트지(1)로부터 분리시킬 수 있게 되는 것이고, 이종시트지(3)가 접착된 상태에서 요홈부(2b) 부분이 접착되지 않은 상태이므로 더욱 수월하게 분리시킬 수 있게 되는 것이다In order to facilitate understanding of the present invention, it is difficult or impossible to separate the extruded sheet 1 and the heterogeneous sheet 3 due to the high adhesive strength, but the present invention can be applied to the PP mixed adhesive 2 (PP) It is possible to separate the different sheet 3 from the extruded sheet 1 because the adhesive force of the component is relatively low and the portion of the recessed portion 2b is not adhered in the state where the different sheet 3 is adhered, As shown in Fig.

따라서, 본 발명은 압출다이(10)를 통해 압출시트지(1)가 토출될 때 압출시트지(1) 상면부에 그 압출시트지(1)의 압출온도 보다 상대적으로 낮은 온도의 PP혼합접착액이 도포되므로 압출다이(10)의 토출공 끝단부 온도가 과도하게 상승 되지 않게 되므로 압출시트지(1)가 일부 타서 발생되는 카본이 발생 되지 않게 되므로 양질의 제품을 얻을 수 있게 되고 지속적인 양산이 가능하게 되고, 그로 인해 불량 감소가 도모 되는 것이다.Therefore, the present invention is characterized in that, when the extruded sheet 1 is discharged through the extrusion die 10, a PP mixed adhesive liquid having a temperature lower than the extrusion temperature of the extruded sheet 1 is applied to the upper surface of the extruded sheet 1 The temperature of the end of the discharge hole of the extrusion die 10 is not excessively increased. As a result, carbon produced from a part of the extruded sheet 1 is not generated, so that a good quality product can be obtained and continuous mass production becomes possible, Thereby reducing defects.

그리고 불량시트가 발생 되면 압출시트지와 이종시트지가 녹아서 융착 된 것이 아니고 분리 가능하게 접착된 것이기 때문에 압출시트지로부터 이종시트지를 떼어내어서 분리시킬 수 있기 때문에 분리된 압출시트지 및 이종시트지를 재활용할 수 있게 되는 것이다.Since the extruded sheet and the dissimilar sheet are melted and not fused and detachably adhered to each other when the defective sheet is generated, the separated sheet can be separated from the extruded sheet and can be separated, so that the separated extruded sheet and the heterogeneous sheet can be recycled .

본 발명은 도면으로 도시되고 설명된 것에 반드시 국한되는 것은 아니고 본 발명이 속하는 기술분야의 통상의 지식을 가진 자에 의해서 여러 가지 형태로 변형 실시될 수 있는 것이므로 청구범위를 크게 벗어나지 않는 한 폭넓게 보호되어야 하는 것은 자명한 것이다.It is to be understood that the invention is not limited to the details shown and described herein, and that various changes and modifications may be made without departing from the scope of the invention as broadly defined by the person skilled in the art. It is self-evident.
