본 발명은 점착층과 원단시이트의 내부결합력이 향상된 스티카원단의 제조방법에 관한 것으로, 특히 점착층이 형성된 이형지와 원단시이트를 접촉하는 접착공정에서, PVC 또는 각종 수지종류의 원단시이트를 수지용융온도에 가까운 온도로 가열한후, 점착처리된 이형지와 압착함으로서 원단시이트 및 점착층이 일체로 결합되어 상호 결합력을 한층 증대시켜 줄 수 있도록 함과 동시에 이같은 스티카를 피접착면에 붙였다 다시 떼어내더라도 점착제가 피접착물을 표면에 남지않도록 하는 내부결합력이 향상된 스티카원단의 제조방법에 관한 것이다.The present invention relates to a method for producing a sticky fabric with improved internal bonding force between the adhesive layer and the fabric sheet. In particular, in the bonding process of contacting the release paper and the fabric sheet on which the adhesive layer is formed, the resin sheet may be formed of a resin sheet containing PVC or various resin types. After heating to a temperature close to, the adhesive sheet is pressed and the original sheet and the adhesive layer are integrally combined to further increase the mutual bonding force, and at the same time, the adhesive may be adhered to the surface to be bonded and then peeled off again. The present invention relates to a method for producing a sticky fabric with improved internal bonding force such that the adherend does not remain on the surface.

스티카원단을 제조하는 종래의 방법으로는 이형지위에 점착제를 도포한후 열처리하여 표면을 건조시킨 다음 이에 점착처리하고자 하는 스티카원단을 접합시키는 방법이 사용되고 있었다.As a conventional method for manufacturing a sticky fabric, a method of applying a pressure-sensitive adhesive to a release paper, followed by heat treatment to dry the surface, and then bonding the sticky fabric to be adhered thereto has been used.

그러나 이와같은 방법으로 제조된 스티카는 원단표면이 경화된 상태에서 점착제층과 결합하게 되는바 결합력이 매우 약하여 스티카사용시 스티카를 피접착면에 붙였다 떼어낼 때 점착제가 피접착물에 남게되는 사용상의 문제점이 지적되고 있어사실상 재사용이 거의 불가능한 것이었다. 즉, 제 3 도는 종래의 방법에 의하여 제조된 스티카원단의 단면도로서, 통상의 방법에 의하면, 이형지(1)위에 점착제(2)를 도포한 다음 열처리하여 표면을 건조시키게 된다. 이때 이형지(1) 상부에 도포된 점착제(2)는 통상의 건조로 (H)를 거치면서 열처리에 의해 경화되어 불규칙한 결합면을 형성하게 되는 것이며, 여기에 다시 원단시이트(3)가 적층되고 압착로울로(4)를 거치면서 접착이 이루어지게 되는 것이다.However, the stica produced in this way is combined with the pressure-sensitive adhesive layer in the state that the fabric surface is hardened, so the bonding strength is very weak. It was pointed out that virtually no reuse was possible. That is, FIG. 3 is a cross-sectional view of a styka fabric produced by a conventional method, and according to a conventional method, the adhesive 2 is coated on a release paper 1, and then heat-treated to dry the surface. At this time, the pressure-sensitive adhesive (2) applied on the upper release paper (1) is to be cured by heat treatment through the normal drying furnace (H) to form an irregular bonding surface, the fabric sheet (3) is again laminated and pressed Through the roller (4) will be made to bond.

이 경우 경화된 점착제(2)의 표면에는 제 3 도에 도시되고 있는 바와같이 표면건조에 의해 생긴 불규칙한 면과 원단시이트(3)사이에 서로 접착이 이루어지지 않은 미세한 공극부(5)(5')가 각각 형성되는데 이형지(1)와 접하고 있는 점착제(2)층의 하부에 비해 노출된체 열처리되는 점착제(2)상부의 공극부(5)가 크게 형성되는 관계로 이같은 공극부(5)로 인해 원단시이트(3)와 점착제(2)간의 결합면(A)이 점착제(2)와 이형지(1)간의 결합면(B)보다 다소 좁거나 거의 동일하게 되어 제조된 스티카를 피접착면에 붙일 때 이형지(1)로부터 분리된 점착제(2) 하부의 접착강도가 오히려 증대된다.In this case, as shown in FIG. 3, the surface of the cured pressure sensitive adhesive 2 has fine pores 5 and 5 'that are not adhered to each other between the irregular surface caused by surface drying and the fabric sheet 3. ) Are formed respectively, and the voids 5 on the pressure sensitive adhesive 2 that are exposed to heat treatment are formed larger than the lower part of the pressure sensitive adhesive 2 layer which is in contact with the release paper 1. Due to the bonding surface (A) between the fabric sheet (3) and the pressure-sensitive adhesive (2) is somewhat narrower or almost the same as the bonding surface (B) between the pressure-sensitive adhesive (2) and the release paper (1) to stick the prepared sticky to the surface to be bonded At this time, the adhesive strength of the lower portion of the pressure-sensitive adhesive 2 separated from the release paper 1 is rather increased.

따라서 피접착면에 접착된 스티카를 떼어낼 경우 공극부(5)에 의해 결합력이 상대적으로 약한 원단시이트(3) 축의 결합면(A)이 분리되면서 점차제(2)는 피접착물에 남게 되는 것이다.Therefore, when removing the sticky adhered to the surface to be bonded, the bonding surface (A) of the shaft of the original sheet (3), which has a relatively weak bonding force, is separated by the voids (5), and gradually the agent (2) remains on the adherend. .

이러한 종래의 문제점을 해소하기 위하여 안출된 본 발명은 점착베(2)가 도포된 이형지(1)와 원단시이트(3)를 압착로울러(4)에서 접합함에 있어서, 공급되는 원단시이트(3)를 드럼형의 가열로울러(6) 및 그 상부에 일정한 간격으로 설치되는 다수의 가열로울러(7)(7')…(7n) 사이로 통과시켜 PVC등 원단시이트(3)를 구성하는 수지의 용융온도에 가까운 130℃ 내지 170℃로 가열한 상태에서 점착처리된 이형지와 압착로울러(4)에 의해 결합되도록 한 것으로, 이와같은 제조방법에 의하여 제공되는 스티카는 원단시이트(3)와 점착제(2)와 결합면(A)이 종래의 스티카에 비해 월등히 넓을뿐만 아니라, 결합강도가 증대되어 같은 점성의 점착제를 사용하더라도 스티카제거시 스티카의 점착제가 피잡착을 표면에 남게되는 폐단을 효과적으로 방지할 수 있게 되는 것이다.The present invention devised in order to solve such a conventional problem is to bond the release sheet 1 and the original sheet 3 to which the adhesive bar 2 is applied in the pressing roller 4, thereby supplying the original sheet 3 to be supplied. Drum-type heating rollers 6 and a plurality of heating rollers 7, 7 'provided at regular intervals thereon. (7 n ) is to be bonded by a pressure-sensitive adhesive (4) with a release paper treated with adhesive in the state heated to 130 ℃ to 170 ℃ close to the melting temperature of the resin constituting the fabric sheet (3) such as PVC, The stica provided by such a manufacturing method is not only much wider than the conventional stica, and the fabric sheet (3), the adhesive (2) and the bonding surface (A), and the bonding strength is increased, so that even if the same viscosity adhesive is used, When the adhesive is removed, the adhesive of the sticky can effectively prevent the closed end that remains on the surface.

이하 본 발명의 제조방법을 첨부한 도면에 따라 상세하게 설명하면 다음과 같다.Hereinafter, the manufacturing method of the present invention will be described in detail with reference to the accompanying drawings.

제 1 도는 본 발명의 제조방법을 공정별로 설명하는 전체공정 예시도이고, 제 2 도는 제 1 도의 방법에 의하여 제조된 스티카원단의 단면도로서, 압착로울러(4)로 공급되는 PVC등의 수지종류 원단시이트(3)가 드럼형의 가열로울러(6) 및 가열로울러(6) 상면에 일정한 간격으로 설치되는 상부 가열로울러(6),(7)(7')…(7n)에 의하여 원단시이트(3)는 수지용융온도에 가까운 130-170℃로 가열되면서 유동성울 갖게 되고, 이와같이 가열된 원단시이트(3)를 점착제(2)가 도포된 이형지(1)와 압착로울러(4)에서 접합하게되는 것이다.FIG. 1 is an exemplary view illustrating the whole process for explaining the manufacturing method of the present invention step by step, and FIG. 2 is a cross-sectional view of the fabric produced by the method of FIG. 1, which is a resin type fabric such as PVC supplied to the pressing roller 4. The upper heating rollers 6, 7, 7 ', in which the sheet 3 is provided at the drum-type heating roller 6 and the upper surface of the heating roller 6 at regular intervals. (7 n ) by the original sheet (3) is heated to 130-170 ℃ close to the melting temperature of the resin will have fluidity, and thus the heated sheet (3) and the release paper (1) coated with the adhesive (2) It is to be joined in the pressing roller (4).

따라서, 이형지(1)위에 도포된 점착제(2)가 건조로 (H)를 거쳐 경화되면서 생긴 불규칙한 결합면(A)의 들어간 부분사이로 유동성을 갖는 원단시이트(3)가 채워져, 제 2 도에서와 같이 공급부(5)를 형성함이 없이 보다 넓은 결합면을 형성하게 된다.Therefore, the flowable sheet 3 having fluidity is filled between the portions of the irregular bonding surface A formed by the adhesive 2 applied on the release paper 1 being cured through the drying furnace H, as shown in FIG. Likewise, a wider coupling surface is formed without forming the supply unit 5.

이어서, 점착처리된 이형지와 압착로울러(4)를 통해 접합되어 견고한 결합력을 갖는 원단시이트(3)는 압착로울러(4)를 통과한 다음 형고정로울러(8)를 거치면서 표면을 평활화하게 되어 완성된 스티카원단(10)을 제공할 수 있게 되는 것이다. 즉, 상술한 제조방법에 의해 제조된 본 발명의 스티카원단(10)은 PVC 등과 같은 수지제 원단시이트(3)와 점착제(2)가 도포된 이형지(1)의 압착로울러(4)로서 접합함에 있어서, 반제품상태의 원단시이트(3)를 드럼형의 가열로울러(6)와 그 상부에 배열되는 가열로울러(7)(7')…(7n) 사이에서 수지용융온도에 가깝게 가열하여 유동성을 부여한 다음, 표면이 경화된 이형지(1)상의 점착제(2)층과 결합될 수 있도록 한 것이어서 스티카 사용시 점착제(2)와 원단시이트(3)가 결합되는 결합면(A)이 일체로 밀착된체 공급부(5)를 형성하여 아니하는 반면, 점착제(2)와 이형지(1)의 결합면(B)에는 이형지(1)에 도포된 점착제(2)의 표면건조에 의해 발생된 공극부(5')가 결합면(B)전체에 고루 분포되어 있어 결합면적이 원단시이트(3)와의 결합면(A)보다 좁은 상태의 결합면(B)을 이루게 된다.Subsequently, the fabric sheet 3 bonded to the adhesive release paper and the pressing roller 4 having a firm bonding force passes through the pressing roller 4 and then smoothes the surface while passing through the mold fixing roller 8. Will be able to provide the sticky fabric 10. That is, the styka fabric 10 of the present invention manufactured by the above-described manufacturing method is bonded to the pressing roller 4 of the release paper 1 coated with a resin fabric sheet 3 such as PVC and the adhesive 2. The semi-finished sheet 3 is placed in a drum-type heating roller 6 and heating rollers 7, 7 'arranged on top thereof. (7 n ) is heated to close to the resin melting temperature to impart fluidity, and then the surface can be combined with the adhesive (2) layer on the cured release paper (1), so that the adhesive (2) and the fabric sheet (3) when using the stick While the bonding surface (A) to which) is bonded does not form an integrally contacted body supply portion (5), the adhesive applied to the release paper (1) on the bonding surface (B) of the pressure-sensitive adhesive (2) and the release paper (1) The gap surface 5 'generated by the surface drying of (2) is evenly distributed over the entire bonding surface B, so that the bonding surface B in a state where the bonding area is narrower than the bonding surface A with the far-end sheet 3 is formed. ) Is achieved.

따라서, 결합면적에 비례하는 점착력의 강조면에서도 원단시이트(3) 및 점착제(2)는 종래의 스티카보다도 월등히 향상된 결합력을 지나게 죄는 것인바, 스티카 사용도중 점착제가 원단싱이트로부터 분리되어 피접착물에 남게되는 사례를 효과적으로 방지할 수 있게 되는 것이다.Therefore, even in the emphasis surface of the adhesive force proportional to the bonding area, the fabric sheet 3 and the adhesive 2 are fastened to a significantly improved bonding strength than the conventional stickers, and the adhesive is separated from the fabric sheet during use of the sticker. This will effectively prevent the cases that remain in the system.
