Description
본 발명은 수용성 실리콘 이형지의 제조방법에 관한 것으로서, 더욱 더 상세하게는 이형지의 기재가 되는 지류의 일면 또는 양면에 수용성 실리콘계 수용액이 균일하게 도포되도록 하는 수용성 실리콘 이형지의 제조방법에 관한 것이다.The present invention relates to a method for producing a water-soluble silicone release paper, and more particularly to a method for producing a water-soluble silicone release paper to uniformly apply the water-soluble silicone-based aqueous solution on one side or both sides of the paper that is the base of the release paper.
종래 실리콘 이형지의 제조방법은 이형지의 기재가 되는 지류의 일측 표면에 폴리에틸렌(PE)수지를 코팅하고, 상기 폴리에틸렌(PE)수지층의 상부에는 용제성 실리콘층을 코팅처리하고 있다.In the conventional method of manufacturing a silicone release paper, a polyethylene (PE) resin is coated on one surface of a feeder which is a base of a release paper, and a solvent-borne silicon layer is coated on the polyethylene (PE) resin layer.
그러나 이러한 종래 실리콘 이형지의 제조방법은 다음과 같은 여러 가지 문제점이 있었다.However, the conventional method of manufacturing a silicone release paper has a number of problems as follows.
첫째, 고열을 요구하는 폴리에틸렌(PE)코팅층과 용제성 실리콘코팅층이 적층되게 지류의 일측표면에 형성시켜야 함으로서, 지류의 표면에 코팅층을 형성시 많은 에너지가 필요하였음은 물론 고가의 압출설비를 필요로 하므로 시설투자비가 많이 소요되었다.First, the polyethylene (PE) coating layer and the solvent-based silicone coating layer requiring high heat should be formed on one surface of the feeder so that the coating layer on the surface of the feeder requires a lot of energy and requires expensive extrusion equipment. Facility investment costs were high.
둘째, 폴리에틸렌(PE)을 지류의 일측면에 코팅시 고열로 용융 살포하여 도포하게 됨으로서, 작업설비나 공정이 까다로워 생산성이 저하되어 생산원가가 상승되는 원인으로 작용되었다.Second, when polyethylene (PE) is coated on one side of the feeder by melting and spraying with high heat, the work equipment or process is difficult and productivity is lowered, resulting in an increase in production cost.
셋째, 사용하고 난 이형지를 폐기시 기재지류와 코팅층을 서로 분리하거나 분해시킬 수 없는 관계로 공해성 폐기물이 양산되었다.Third, when waste paper used was discarded, pollutant waste was mass-produced because the base paper and the coating layer could not be separated or decomposed.
따라서 이를 처리하기 위해서는 별도의 소각로 등과 같은 처리설비를 필요로 하게 됨으로서, 사용하고 난 이형지를 그대로 방치한 상태로 폐기시키는 실정이므로 환경을 오염시키게 되는 문제점이 있었다.Therefore, in order to process this requires a separate treatment facility such as an incinerator, because the situation is used to leave the release paper used as it was, there was a problem that contaminates the environment.
본 발명의 목적은 상기 종래와 같은 문제점을 해결하기 위해, 물 800∼900중량부에 수용성 실리콘 유효성분 20∼40%인 원액을 5∼10중량부혼합한 다음 여기에 백금계 촉매 0.8∼1.5중량부와 폴리디메칠실리콘 8∼10중량부를 혼합한 혼합물을 바드에 투입하는 투입단계와, 상기 바드로 권취축에 감겨진 기재지류를 이송시키는 이송단계와, 상기 기재지류가 바드에 보관중인 혼합물을 균일한 두께로 도포하여 피막층을 형성하는 피막층 형성단계와, 상기 피막층이 형성된 기재지류를 80℃∼90℃의 온도의 건조로를 통과시키면서 10초∼20초 동안 건조시키는 건조단계와, 상기 건조단계에서 이형층이 형성된 기재지류를 권취로울러에 건취시키는 배출단계를 거쳐 수용성 실리콘 이형지를 제조함으로서, 기재지류의 표면에 이형층을 형성시에도 별도의 압출라인을 필요로 하지 않게 되어 작업설비나 공정이 단순화됨으로서, 생산성이 향상되고 상기와 같이 제조되어 사용된 이형지를 폐기시, 상기 기재지류에 코팅된 수용성 실리콘의 수지층을 물에 접촉시키는 것에 의해 상기 코팅층이 기재지류로부터 분해 및 분리됨으로서, 상기 기재지류를 재사용할 수 있게 되어 산업폐기물의 발생이 억제되도록 하는 수용성 실리콘 이형지의 제조방법을 제공하는 데 있다.An object of the present invention is to solve the problem as described above, 5 to 10 parts by weight of a stock solution containing 20 to 40% water-soluble silicone active ingredient in 800 to 900 parts by weight of water and then 0.8 to 1.5 weight of platinum catalyst And a feeding step of feeding a mixture of 8 to 10 parts by weight of polydimethylsilicone and polydimethylsilicone to the bard, a conveying step of transferring the substrate paper wound on the winding shaft to the bar, and a mixture of the substrate paper stored in the bard. A coating layer forming step of applying a uniform thickness to form a coating layer, a drying step of drying the substrate paper on which the coating layer is formed for 10 seconds to 20 seconds while passing through a drying furnace at a temperature of 80 ℃ to 90 ℃, in the drying step By manufacturing the water-soluble silicone release paper through the discharge step of drying the substrate paper on which the release layer is formed on the winding roller, a separate extrusion line is formed even when the release layer is formed on the surface of the substrate paper. By eliminating the need for simplification of work facilities and processes, the productivity is improved and when the release paper used and manufactured as described above is discarded, the coating layer is brought into contact with water by contacting the resin layer of water-soluble silicone coated on the base paper. It is to provide a method for producing a water-soluble silicone release paper that can be reused and separated from the base paper, so that the base paper can be reused to suppress the generation of industrial waste.

본 발명의 수용성 실리콘 이형지의 제조방법은 도 1 내지 도 3에 도시하고 있는 바와 같이, 물 800∼900중량부에 수용성 실리콘 유효성분 20∼40%인 원액을 5∼10중량부혼합한 다음 여기에 백금계 촉매 0.8∼1.5중량부와 폴리디메칠실리콘 8∼10중량부를 혼합한 혼합물(C)을 바드(110)에 투입하는 투입단계(100)와,1 to 3, the method for producing a water-soluble silicone release paper of the present invention is mixed with 5 to 10 parts by weight of a stock solution containing 20 to 40% water-soluble silicone active ingredient in 800 to 900 parts by weight of water. An input step (100) of introducing a mixture (C) of 0.8 to 1.5 parts by weight of platinum-based catalyst and 8 to 10 parts by weight of polydimethylsilicone into the bard 110;
상기 바드(110)로 권취축(210)에 감겨진 기재지류(600)를 이송시키는 이송단계(200)와,A transfer step 200 for transferring the base paper 600 wound around the winding shaft 210 to the bard 110;
상기 기재지류(600)가 바드(110)에 보관중인 혼합물(C)을 균일한 두께로 도포하여 피막층을 형성하는 피막층 형성단계(300)와,The coating layer forming step 300 of forming a coating layer by coating the mixture (C) in the base paper 600 stored in the bard 110 to a uniform thickness, and
상기 피막층이 형성된 기재지류(600)를 80℃∼90℃의 온도의 건조로(410)를 통과시키면서 10초∼20초 동안 건조시키는 건조단계(400)와,A drying step 400 of drying the substrate paper 600 on which the coating layer is formed for 10 seconds to 20 seconds while passing through a drying furnace 410 having a temperature of 80 ° C. to 90 ° C .;
상기 건조단계(400)에서 이형층(610)이 형성된 기재지류(600)를 권취로울러(510)로 권취시키는 배출단계(500)를 거쳐 제조됨을 그 기술적 구성상의 기본 특징으로 한다.The technical feature of the technical configuration is that the drying step 400 is manufactured through the discharge step 500 to wind the substrate paper 600, the release layer 610 is formed in the winding roller 510 in the drying step (400).
이때, 상기 혼합물(C)에 혼합된 수용성 실리콘 유효성분의 함량이 20% 이하이면 박리성이 저하되어 제대로 이형이 이루어지지 않게 되고, 상기 수용성 실리콘 유효성분의 함량이 40% 이상인 경우에는 고가인 원액의 사용량이 증가되어 생산원가가 상승하게 된다.At this time, when the content of the water-soluble silicone active ingredient mixed in the mixture (C) is 20% or less, the peelability is lowered, so that mold release is not performed properly, and when the content of the water-soluble silicone active ingredient is 40% or more, expensive stock solution The production cost increases due to the increase in the amount of.
이와 같이 구성되는 본 발명은, 물 800∼900중량부에 수용성 실리콘 유효성분 20∼40%인 원액을 5∼10중량부혼합한 다음 여기에 백금계 촉매 0.8∼1.5중량부와 폴리디메칠실리콘 8∼10중량부를 혼합한 혼합물(C)이 바드(110)의 내부로 투입단계(100)에 투입되고, 상기 바드(110)의 내부로는 권취축(210)에 감겨진 기재지류(600)가 이송단계(200) 및 피막층 형성단계(300)를 거치면서 외측면에 혼합물이 도포되어 상기 기재지류(600)의 표면에 균일한 두께의 피막층이 도포된다.According to the present invention, 5 to 10 parts by weight of a stock solution containing 20 to 40% of a water-soluble silicone active ingredient is mixed with 800 to 900 parts by weight of water, followed by 0.8 to 1.5 parts by weight of a platinum-based catalyst and polydimethylsilicone 8 The mixture (C) mixed with ~ 10 parts by weight is introduced into the charging step (100) into the interior of the bar (110), the substrate paper 600 wound around the winding shaft (210) inside the bar (110) The mixture is applied to the outer surface while the transfer step 200 and the film layer forming step 300 are applied to the film layer having a uniform thickness on the surface of the substrate paper 600.
상기 혼합물에 백금계 촉매를 투입하는 이유는 혼합물이 수용성인데도 낮은 온도에서 건조를 촉진시켜 건조에 따른 온도를 최대한 낮춤과 동시에 건조시간을 단축시키기 위함이다.The reason why the platinum-based catalyst is added to the mixture is to accelerate the drying at a low temperature even though the mixture is water-soluble, so as to reduce the temperature according to drying as much as possible and to shorten the drying time.
상기 피막층 형성단계(300)를 본 발명의 일 실시예로 도시한 도 2는 기재지류(600)가 메쉬로울러(310) 및 옵셋고무로울러(320)와 압동로울러(330)를 통과하면서 바드(110)에 담겨진 혼합물(C)이 기재지류(600)의 표면에 도포되는 그라비아 옵셋코트방식을 나타내었으나, 코마 코트(COMMA COAT)방식, 리버스 코트방식, 에어 나이프 코트방식, 메이어 바 코트방식, 나이프 코트방식 등 기타 공지된 여러 가지 방식에 의해 기재지류(600)의 표면에 피막층을 형성할 수 있으므로 피막층 형성단계의 방식을 한정하지 않는다.2 shows the film layer forming step 300 as an embodiment of the present invention, while the substrate paper 600 passes through the mesh roller 310, the offset rubber roller 320, and the pressure roller 330. ) Shows a gravure offset coat method in which the mixture (C) contained in the) is applied to the surface of the base paper 600, but a comma coat method, a reverse coat method, an air knife coat method, a meyer bar coat method, and a knife coat Since the coating layer can be formed on the surface of the substrate paper 600 by various other methods such as the method, the method of the coating layer forming step is not limited.
