Description
본 발명은 천연 피혁의 고감성을 구현함과 동시에 인체유해 물질이 배제된 친환경 물질로 구현되는 수성 실리콘 합성피혁의 제조방법 및 그 제조방법에 따라 제조된 친환경 실리콘 합성피혁에 관한 것이다. The present invention relates to a method for manufacturing a water-based silicone synthetic leather that implements the high sensitivity of natural leather while being implemented with an eco-friendly material that excludes substances harmful to the human body, and to an eco-friendly silicone synthetic leather manufactured according to the manufacturing method.
기존 우레탄 코팅(습식, 건식)시 유기 용제를 사용함으로써 피부트러블 등의 문제가 있었다. There were problems such as skin troubles due to the use of organic solvents in existing urethane coatings (wet and dry).
이러한 문제로 VOC규제가 강화되어 피부패치 제조에 사용되는 솔벤트 PU나 PVC의 사용이 제한되었고, 그로 인하여 유아 및 어린이용 매트(matt), 자동차용 시트, 가구용 소파(sofa) 또는 밴딩테이프, 자석파스, 자외선 패치, 리플패치 등 피부접촉 분야에 다양하게 적용할 수 있는 무독성 친환경 합성피혁 제품의 개발이 절실히 요구되는 현실이다. Due to these issues, VOC regulations have been strengthened, restricting the use of solvents such as PU or PVC used in the manufacture of skin patches. As a result, there is an urgent need for the development of non-toxic, eco-friendly synthetic leather products that can be applied in various skin contact fields such as mats for infants and children, car seats, sofas for furniture, or banding tapes, magnetic patches, UV patches, and ripple patches.
현재 다양한 분야에서 요구되는 스팩에 맞는 친환경 코팅기술의 개발이 더디게 이루어지는 것이 현실이다. The reality is that the development of eco-friendly coating technology that meets the specifications required in various fields is slow.

상기 제1단계에 의해 제조된 실리콘원단(60)은 도 3의 (a)에 도시된 바와 같이, 이형PET필름 또는 이형지(RP)상에 도포되어 형성되는 수성우레탄(PUD)층, 상기 수성우레탄층상에 형성되는 프라이머층, 상기 프라이머층상에 도포되어 형성되는 실리콘프라이머층 및 상기 실리콘프라이머층상에 합지되는 원단층으로 구성되어진다. The silicone fabric (60) manufactured by the above first step is composed of a water-based urethane (PUD) layer formed by being applied on a release PET film or release paper (RP), a primer layer formed on the water-based urethane layer, a silicone primer layer formed by being applied on the primer layer, and a fabric layer laminated on the silicone primer layer, as shown in (a) of FIG. 3.

In addition, after the first step, if the second step is performed, as shown in (b) of Fig. 3, a silicone layer is formed by coating the other surface of the water-based polyurethane (PUD) layer manufactured by the first step, and a release PET film or release paper (RP) is laminated to one surface of the silicone layer, thereby completing the final silicone synthetic leather.
본 발명에 따르면, 상기 (가)단계에서 사용되는 수성우레탄은 수성우레탄 (PUD:ASF811D, Dihydrogen oxide)를 사용하고, 상기 (나)단계의 프라이머(Primer)는 리퀴드 실리콘 러버(Liquid Silicon Rubber)를 사용하는 것이 좋다. 이때, 상기 수성우레탄(PUD)의 도포두께가 임계치를 벗어날 경우에는 표면 기포현상이 발생하거나 혹은 도포되고 난 후, 양측면이 굳는현상이 나타날 수 있는 문제가 있을 수 있고, 상기 프라이머는 후속단계에서 사용되는 실리콘프라이머와 수성PUD를 접착시키는 용도로 사용되는 것으로, 그 도포 두께가 임계치를 벗어날 경우에는 표면층 함침현상이 일어나거나, 혹은 박리불가 현상이 일어날 수 있는 문제가 있을 수 있다. According to the present invention, it is preferable that the water-based urethane used in the step (a) is water-based urethane (PUD: ASF811D, Dihydrogen oxide), and the primer in the step (b) is liquid silicone rubber. At this time, if the coating thickness of the water-based urethane (PUD) exceeds the critical value, there may be a problem that surface bubbling may occur or both sides may harden after coating, and the primer is used to adhere the silicone primer used in the subsequent step to the water-based PUD, and if the coating thickness exceeds the critical value, there may be a problem that surface layer impregnation may occur or an inability to peel may occur.
본 발명에 따르면, 바람직하게 상기 (다)단계의 실리콘 프라이머는 경도 18, 신율 900%의 물성을 가지는 #8900(제조사:SJS Silicone, 제품명: SJS 8900A, 화합물명: Siloxanes Silicones di-me, Vinyl Group-Terminated) 90~95중량부 및 희석제 15~20중량부를 포함하도록 혼합한 혼합물을 사용한다. 이때, 상기 #8900의 혼합량이 임계치 범위를 벗어날 경우에는 r경화불량의 문제, 혹은 접합층의 분리현상이 일어나는 문제가 있을 수 있다. According to the present invention, preferably, the silicone primer of the (multi) step uses a mixture containing 90 to 95 parts by weight of #8900 (manufacturer: SJS Silicone, product name: SJS 8900A, compound name: Siloxanes Silicones di-me, Vinyl Group-Terminated) having properties of hardness of 18 and elongation of 900% and 15 to 20 parts by weight of a diluent. At this time, if the mixing amount of the #8900 is out of the critical range, there may be a problem of poor r-curing or a problem of separation of the bonding layer.

According to the present invention, the liquid silicone of step (A) is a mixture containing 85 to 90 parts by weight of #8077 (manufacturer: Sejin Silicone, product name: SL-8077, compound name: Siloxanes and Silicones, di-Me, Me vinyl, vinyl group-terminated) having properties of 50% hardness and 400% elongation as a main body and 10 to 15 parts by weight of a diluent. At this time, if the amount of #8077 used exceeds the critical value, there may be a problem that surface cracking occurs or that release PET or release paper (RP) is separated. In addition, if the coating thickness exceeds the critical value, the mixture may be in an uncured state or there may be a problem that adhesive strength is reduced.
