Description
본 발명은 점착 이형지의 점착제가 코팅될 면에 양각의 연속된 선을 가로, 세로 방향으로 엠보싱함으로써 종전의 점착 시트류의 접착 시공시 시트층의 부풀음 현상으로 인한 시공의 불편함을 해소하여 시공성을 향상시키도록 하는 점착 이형지 및 그 이형지를 이용한 점착 시트 제품에 관한 것이다.The present invention solves the discomfort of the construction due to the swelling of the sheet layer during adhesive bonding of conventional adhesive sheets by embossing a continuous line of embossed in the horizontal, vertical direction on the surface to be coated with the adhesive of the adhesive release paper The present invention relates to an adhesive release paper for improving and an adhesive sheet product using the release paper.
요즘 대부분 철판 보호, 광고, 인테리어용 등에 점착 시트류가 주로 사용되어지고 있다. 이러한 점착 시트를 제조하기 위해서는 압연이나 캐스팅 공법으로 시트를 생산한 후 이형지 위에 점착제를 코팅하고 점착제가 코팅된 면과 시트층을 합지하여 생산한다.Nowadays, adhesive sheets are mainly used for iron plate protection, advertisement, and interior use. In order to manufacture such an adhesive sheet, the sheet is produced by rolling or casting, and then the adhesive is coated on a release paper, and the adhesive-coated side and the sheet layer are produced by laminating.
여기에 사용되는 이형지는 시공시 점착제로부터 박리가 쉽게 되도록 이형제를 처리하여 사용한다. 이형제로는 주로 규소 원자와 탄소 원자가 결합한 실록산(siloxane) 골격으로 규소 원자에 메틸기, 페놀기의 유기기가 결합한 구조를 갖는 폴리실록산(polysiloxane)이 대부분을 차지한다. 이형제는 실리콘 희석액을 기재 표면에 코팅하고 용제를 건조시킨 후 경화시킨다. 이형지에 사용되는 기재는 보다 소량의 실리콘으로 우수한 박리 성능을 얻기 위해 실리콘이 기재 내부로 침투되는 것을 적게 하고 표면을 평활하게 하는 것이 바람직하다. 이형지에 사용되는 기재는 용도에 따라 다르지만 주로 사용하고 있는 것은 폴리라미네이트(polylaminate)지, 글래싱(glassing)지, 크라프트지, 클레이 코트(clay coat)지, 합성지, 알루미늄박, 각종 플라스틱 필름(폴리에틸렌, 폴리프로필렌, 폴리에틸렌테트라프탈레이트, 폴리비닐클로라이드) 등 이고 , 특히 최근 들어 젖어들지 않고 평활하고 강도가 강한 투명한 플라스틱 필름이 주목되고 있다. 크라프트 점착 테이프용 이형지는 기재로 칭량(稱量) 70g/㎠의 크라프트지를 사용하여 편면(片面)에 폴리에틸렌(polyethylene), 폴리프로필렌(polypropylene) 등의 올레핀(olefin)계 수지를 압출 코팅(extrusion coating)한 후, 그 위에 실리콘계 수지로 이형 처리층을 부여한 구조로 설계한 것이다. 양면(兩面) 점착 테이프용 박리지는 종래의 화지를 점착제 지지체로 한 것부터, 지지체가 없는 점착제 단독에 의한 제품, 각종 필름을 점착제 지지체로 이용한 것 등 다양하게 사용되고 있다. 이러한 점착 이형지는 대부분 도 1과 같은 구조로 이루어져 있다.The release paper used herein is used by treating the release agent so that peeling from the pressure-sensitive adhesive is easy during construction. As the releasing agent, a polysiloxane having a structure in which a methyl group and a phenol group are bonded to a silicon atom mainly comprises a siloxane skeleton in which silicon atoms and carbon atoms are bonded. The release agent is coated with a silicone diluent on the surface of the substrate, and dried and cured. The substrate used for the release paper is preferably made of less silicon to penetrate into the substrate and smooth the surface in order to obtain excellent peeling performance with a smaller amount of silicone. The substrate used for the release paper varies depending on the application, but the main ones are polylaminate, glassing, kraft paper, clay coat paper, synthetic paper, aluminum foil, and various plastic films (polyethylene , Polypropylene, polyethylenetetraphthalate, polyvinyl chloride) and the like, and in particular, recently, a transparent plastic film that is smooth and strong without getting wet has been attracting attention. Release paper for kraft adhesive tape is extruded and coated with olefin resin such as polyethylene and polypropylene on one side by using kraft paper weighing 70g / cm 2 as a base material. After that, it is designed in the structure which provided the mold release process layer with silicone resin on it. Release papers for double-sided adhesive tapes are used in a variety of ways, such as those using conventional paper as an adhesive support, products using an adhesive alone without a support, and various films used as an adhesive support. Such adhesive release paper is composed of a structure as shown in FIG.
즉, 도 1a는 크라프트지(4) 편면에 폴리에틸렌을 압출 코팅(3)한 후 그 위에 실리콘을 코팅(1)을 한 것이고, 도 1b는 세미글래싱(semi-glassing)지(5)의 양면에 실리콘을 직접(Direct) 코팅(2,2) 한 것이며 도 1c는 백색 상질지 또는 크라프트지(6) 양면에 폴리에틸렌을 압출코팅(3,3)한 후 실리콘을 코팅(1,1)한 것이고, 도 1d는 세미글래싱지(5)의 한면에 실리콘을 직접 코팅하고(2) 다른면에 폴리에틸렌을 압출 코팅(3)한 후 그 위에 실리콘을 코팅(1)한 것이다.In other words, Figure 1a is an extrusion coating (3) of polyethylene on one side of the kraft paper (4) and then a silicone coating (1) on it, Figure 1b is a double-sided of semi-glassing paper (5) Direct coating (2,2) on the silicon, Figure 1c is a polyethylene (1,1) after the extrusion coating (3,3) of polyethylene on both sides of the white fine paper or kraft paper (6) Figure 1d is a silicone directly coated on one side of the semi-glas paper (2) and the extrusion coating (3) of polyethylene on the other side (1).
이렇게 제조되는 이형지는 점착제가 코팅되는 면의 평활도가 뛰어나도록 하는데, 그 이유는 이형지 위에 점착제가 코팅될 때 점착제의 균일한 코팅이 되게 함으로써 시공시 부분별 점착력을 균일하게 해 준다. 점착 시트 시공시 사용되는 기재로는 철재류, 섬유류, 아크릴 판, 유리, 목재 등이 있다. 이러한 점착 시트류를 사용할 때에는 원하는 문자나 모양을 제작한 다음 이형지를 점착 시트로부터 박리 후 점착 시트를 기재에 접착 시공함으로써 이루어진다. 이러한 시트와 기재의 접착 시공시 점착 시트(7)의 점착제층(8)과 기재층(9) 사이로 공기가 빠져 나가지 못하여, 도 2와 같이 기포(11) 발생으로 인한 시트층의 부풀음 현상(12)이 초래된다. 이로 인해 시공의 불편함과 시공 불량이 초래된다.The release paper thus prepared is excellent in the smoothness of the surface on which the pressure-sensitive adhesive is coated, the reason is that when the pressure-sensitive adhesive is coated on the release paper to make a uniform coating of the pressure-sensitive adhesive during construction. Substrates used in the construction of the adhesive sheet include iron materials, fibers, acrylic plates, glass, wood, and the like. When using such adhesive sheets, a desired letter or shape is produced, and then the release sheet is peeled from the adhesive sheet and then the adhesive sheet is adhered to the substrate. When the sheet and the base material are bonded to each other, air does not escape between the pressure-sensitive adhesive layer 8 and the base material layer 9 of the pressure-sensitive adhesive sheet 7, and thus, the swelling phenomenon of the sheet layer due to the bubble 11 is generated as shown in FIG. ) Is caused. This results in inconvenient construction and poor construction.
이에 본 발명은 위에 제기된 문제점을 개선하여, 시공의 편리함과 시공 불량을 최소화시키는 우수한 시공성을 가지도록 한 점착 이형지 및 그 이형지를 이용한 점착 시트 제품에 관한 것이다.Accordingly, the present invention improves the problems posed above, and relates to a pressure-sensitive adhesive release paper and a pressure-sensitive adhesive sheet product using the release paper to have excellent construction properties to minimize the convenience of construction and poor construction.

상기한 바와 같은 목적을 달성하기 위해서는 점착 이형지의 점착제가 코팅될 면에 약 0.1㎜ ∼ 3.0㎜ 간격으로 도 3과 같이 양각의 여러가지 모양의 연속된 선이 가로, 세로 방향으로 이형지 위에 엠보싱되어 있어야 한다. 이때 엠보싱된 면의 형태는 도 4와 같아야 한다.In order to achieve the object as described above, a continuous line of various shapes of embossed lines should be embossed on the release paper in the horizontal and vertical directions as shown in FIG. 3 at intervals of about 0.1 mm to 3.0 mm on the surface on which the adhesive of the adhesive release paper is to be coated. . At this time, the shape of the embossed surface should be as shown in FIG.
만약 엠보싱된 양각면의 위폭이 아래폭보다 크면 이형지 위에 코팅된 점착제가 시트로 전사될 때 점착제가 완전히 시트로 전사되지 않는다. 밑폭은 10㎛ ∼ 150㎛이며 높이는 5㎛ ∼ 50㎛가 적합하다.If the upper width of the embossed embossed surface is larger than the lower width, the adhesive is not completely transferred to the sheet when the adhesive coated on the release paper is transferred to the sheet. Bottom width is 10 micrometers-150 micrometers, and 5 micrometers-50 micrometers of height are suitable.
폭이 너무 좁으면 기포가 잘 빠져 나가지 않고 너무 넓으면 점착제의 코팅될 면이 적어 접착 효과가 저하된다. 높이가 너무 낮으면 기포가 빠져 나가는 효과가 적어진다. 이러한 양각의 연속된 선을 지닌 이형지를 제조하는 방법은 도 5와 같이 지지대층 위에 폴리에틸렌이나 폴리프로필렌 등의 올레핀계 수지를 티-다이(T-Die)를 통해 압출 코팅한 다음, 냉각 롤(roll)을 이용하여 냉각시키고, 그 위에 실리콘을 코팅하여 건조 오븐을 이용하여 경화시킨다. 그리고 나서 엠보싱 공법으로 가로, 세로 방향의 연속된 선을 양각으로 형성시킨다.If the width is too narrow, bubbles are not easily escaped, and if the width is too wide, the surface to be coated of the pressure-sensitive adhesive is less and the adhesive effect is lowered. If the height is too low, the bubble is less effective to escape. The method of manufacturing a release paper having a continuous line of embossed, as shown in Figure 5 by extrusion coating the olefin resin such as polyethylene or polypropylene on the support layer through a T-Die, and then a cooling roll (roll) ), The silicone is coated on it and cured using a drying oven. An embossing method is then used to emboss the continuous lines in the transverse and longitudinal directions.
이렇게 제조된 이형지 위에 점착제를 코팅한 후 점착제층을 매개로 시트층과 합지한다.After coating the pressure-sensitive adhesive on the release paper thus prepared is laminated with a sheet layer through the pressure-sensitive adhesive layer.
제품 사용시 이형지를 점착 시트로부터 박리하면 점착제는 시트층에 전사된다. 이때 이형지의 양각된 모양이 도 6과 같이 점착제층에 골 형태로 나타난다. 이로 인해 점착 시트와 기재층의 점착 시공시 점착제층에 골이 형성되어 점착제층과 기재층 사이의 공기가 골 부분으로 빠져 나가 기포가 발생되지 않고, 이로 인하여 시트층의 부풀음 현상을 방지하여 시공성이 우수한 점착 시트류를 생산해 낼 수 있다.The adhesive is transferred to the sheet layer when the release paper is peeled off from the adhesive sheet during use of the product. At this time, the embossed shape of the release paper appears in the form of bone in the pressure-sensitive adhesive layer as shown in FIG. Therefore, when the adhesive sheet and the adhesive layer of the base material is formed in the pressure-sensitive adhesive layer, air between the pressure-sensitive adhesive layer and the base layer escapes to the bone portion and bubbles are not generated, thereby preventing swelling of the sheet layer. Excellent adhesive sheets can be produced.
