Description

실사인쇄층이 형성된 완충 매트 {CUSHIONING MAT WITH ACTUAL IMAGE PRINTING LAYER}Buffer mat with real print layer {CUSHIONING MAT WITH ACTUAL IMAGE PRINTING LAYER}

개시된 내용은 실사인쇄층이 형성된 완충 매트에 관한 것으로, 더욱 상세하게는 실사인쇄층이 형성된 코팅층이 적용되어 사용중에 인쇄층의 이격이 발생하지 않고, 압력에 의해 눌린부분이 천천히 회복되는 성능을 나타내는 실사인쇄층이 형성된 완충 매트에 관한 것이다.
The disclosed content relates to a buffer mat with a real print layer, and more specifically, a coating layer with a real print layer is applied so that the separation of the printed layer does not occur during use, and the pressed part is slowly recovered by pressure. It relates to a cushioning mat on which a real print layer is formed.

일반적으로 아파트 등과 같은 공동주택의 경우는 바닥슬래브와 경량기포 콘크리트층 사이에 층간소음을 저감시키는 완충흡음재가 개재되지만, 측강소음은 여전히 공동주택에서 입주민 간의 주 분쟁원인으로 지목되고 있다.In general, in the case of apartments, such as apartments, a cushioning sound absorbing material is interposed between the floor slab and the lightweight foamed concrete layer to reduce inter-floor noise, but side-gang noise is still pointed out as the main cause of dispute among residents in apartments.

또한, 일반주택이나 빌라 등과 같은 건물에는 경량기포 콘크리트층 사이에 층간소음을 저감시키는 완충흡음재가 개재되지 않아 생활 상에서 발생되는 진동 및 소음이 상층으로부터 하층으로 전달되는 비율이 높은 문제점이 있었다.In addition, in buildings such as general houses and villas, there is a problem in that the ratio of vibration and noise generated in daily life is transmitted from the upper floor to the lower floor is high because a cushioning and absorbing material for reducing inter-floor noise is not interposed between the lightweight foamed concrete layers.

상기의 문제점을 해소하기 위해 아파트와 같은 공동주택과 일반주택 또는 빌라 등과 같은 복층건물의 바닥에는 다수개가 서로 조립된 상태로 배열되는 소정 크기의 완층 매트가 많이 적용되고 있는데, 이러한 완충 매트는 층간소음을 줄여줄 뿐만 아니라, 유아들이 넘어지면서 다치는 것을 방지하는 이중 효과를 나타낸다.In order to solve the above problems, a large number of full-sized mats of a predetermined size are applied to the floors of multi-story buildings such as apartments and general houses or villas. In addition to reducing the amount, it has a dual effect of preventing infants from falling and getting hurt.

종래에 완충매트는 폴리에틸렌 등과 같은 합성수지를 발포성형하여 형성되는 매트블럭본체와, 상기 매트블럭본체의 가장자리를 따라 형성되어 인접될 매트블럭본체가 조립되도록 하는 요철결합부로 이루어지는데, 상기의 구조를 나타내는 종래의 완충매트는 아동의 기호도를 높이기 위해 각종 케릭터가 인쇄된 인쇄층이 별도로 형성되는데, 상기 인쇄층은 완충 매트를 사용하는 과정에서 이격되는 현상이 발생하여 제품이 쉽게 손상될 뿐만 아니라 잡음을 유발하는 문제점이 있고, 외력에 의해 눌린 부분이 빠르게 복원되어 유아들이 완충 매트 위에서 걸음을 잘 걷지 못하고 쉽게 넘어지는 문제점이 있었다.
Conventionally, a buffer mat consists of a mat block body formed by foam molding a synthetic resin such as polyethylene, and an uneven coupling part formed along the edge of the mat block body to assemble the mat block body to be adjacent. Conventional cushioning mats have a separate printing layer on which various characters are printed in order to enhance children's preference, and the printing layer is separated from each other in the process of using the cushioning mat, which not only damages the product, but also causes noise. There is a problem that the pressed part is quickly restored by an external force, so that infants cannot walk well on the cushioning mat and fall easily.

개시된 내용은 실사인쇄층이 형성된 코팅층이 적용되어 사용중에 인쇄층의 이격이 발생하지 않고, 압력에 의해 눌린부분이 천천히 회복되는 성능을 나타내는 실사인쇄층이 형성된 완충 매트를 제공하는 것이다.
Disclosed is to provide a cushioning mat with a real printed layer that exhibits the ability to slowly recover a pressed part by pressure without causing a separation of the printed layer during use by applying a coating layer on which the real printed layer is formed.

하나의 일 실시예로서 이 개시의 내용은 폴리우레탄으로 이루어지는 기재층 및 상기 기재층의 일면에 형성되며 실사인쇄층이 형성된 코팅층으로 이루어지는 것을 특징으로 하는 실사인쇄층이 형성된 완충 매트에 대해 기술하고 있다.As one embodiment, the content of this disclosure describes a buffer mat with a real print layer, characterized in that it comprises a base layer made of polyurethane and a coating layer formed on one side of the base layer and with a real print layer. .

바람직하기로는, 상기 기재층은 0.5 내지 10센티미터의 두께로 형성될 수 있다.Preferably, the base layer may be formed to a thickness of 0.5 to 10 cm.

더 바람직하기로는, 상기 기재층은 폴리올 100 중량부, 물 0.5 내지 2 중량부, 트리에틸렌디아민 0.5 내지 1.5 중량부, 계면활성제 1 내지 2 중량부, 이소시아네이트 20 내지 40 중량부를 발포하여 제조될 수 있다.More preferably, the base layer may be prepared by foaming 100 parts by weight of polyol, 0.5 to 2 parts by weight of water, 0.5 to 1.5 parts by weight of triethylenediamine, 1 to 2 parts by weight of surfactant, and 20 to 40 parts by weight of isocyanate .

더욱 바람직하기로는, 상기 코팅층은 표면에 코로나 방전처리된 10 내지 100㎛ 두께의 열가소성 폴리우레탄으로 이루어질 수 있다.More preferably, the coating layer may be formed of a 10 to 100 μm-thick thermoplastic polyurethane subjected to corona discharge treatment on the surface.

더욱 더 바람직하기로는, 상기 실사인쇄층은 합성수지 100 중량부에 희석제 50 내지 80 중량부, 습윤제 0.05 내지 1.5 중량부 및 경화제 0.01 내지 40 중량부를 혼합하여 이루어지며, 상기 합성수지는 폴리메틸메타아크릴레이트, 폴리우레탄, 폴리비닐알코올 및 에폭시로 이루어진 그룹에서 선택된 하나로 이루어질 수 있다.
Even more preferably, the real print layer is made by mixing 50 to 80 parts by weight of a diluent, 0.05 to 1.5 parts by weight of a wetting agent, and 0.01 to 40 parts by weight of a curing agent to 100 parts by weight of synthetic resin, and the synthetic resin is polymethyl methacrylate, It may be made of one selected from the group consisting of polyurethane, polyvinyl alcohol and epoxy.

이상에서와 같은 실사인쇄층이 형성된 완충 매트는 실사인쇄층이 형성된 코팅층이 적용되어 사용중에 인쇄층의 이격이 발생하지 않고, 압력에 의해 눌린부분이 천천히 회복되는 탁월한 효과를 나타낸다.
The cushioning mat on which the real print layer is formed as described above has an excellent effect in that the coating layer on which the real print layer is formed is applied so that the separation of the print layer does not occur during use, and the pressed part is slowly recovered by pressure.

도 1은 개시된 일 실시예에 따른 실사인쇄층이 형성된 완충 매트를 나타낸 분해사시도이다.1 is an exploded perspective view showing a cushioning mat on which a real print layer is formed according to an exemplary embodiment disclosed herein.

이하에는, 본 발명의 바람직한 실시예와 각 성분의 물성을 상세하게 설명하되, 이는 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 발명을 용이하게 실시할 수 있을 정도로 상세하게 설명하기 위한 것이지, 이로 인해 본 발명의 기술적인 사상 및 범주가 한정되는 것을 의미하지는 않는다.
Hereinafter, a preferred embodiment of the present invention and the physical properties of each component will be described in detail, but this is for explaining in detail enough that one of ordinary skill in the art can easily implement the invention, This does not mean that the technical spirit and scope of the present invention are limited.

개시된 실사인쇄층이 형성된 완충 매트는 폴리우레탄으로 이루어지는 기재층(10) 및 상기 기재층(10)의 일면에 형성되며 실사인쇄층(21)이 형성된 코팅층(20)으로 이루어진다.
The disclosed buffer mat on which the real print layer is formed includes a substrate layer 10 made of polyurethane and a coating layer 20 formed on one surface of the substrate layer 10 and on which the real print layer 21 is formed.

상기 기재층(10)은 개시된 완충 매트의 기재가 되는 층으로, 0.5 내지 10 센티미터 두께의 폴리우레탄으로 이루어지는데, 상기 기재층(10)의 두께가 0.5 센티미터 미만이면 개시된 완충 매트의 충격완화 효과가 저하되며, 상기 기재층(10)의 두께가 10센티미터를 초과하게 되면 완충효과는 향상되지만 외력에 의해 매트가 눌리는 깊이가 지나치게 증가하여 유아들이 걷기에 불편하고 매트의 보관성도 저하된다.The base layer 10 is a layer that serves as a base material of the disclosed cushioning mat, and is made of polyurethane having a thickness of 0.5 to 10 cm. If the thickness of the base layer 10 is less than 0.5 cm, the impact relaxation effect of the disclosed cushioning mat is When the thickness of the base layer 10 exceeds 10 cm, the cushioning effect is improved, but the depth at which the mat is pressed by an external force is excessively increased, making it uncomfortable for infants to walk and storage of the mat is also reduced.

더욱 상세하게는 상기 기재층(10)을 구성하는 폴리우레탄은 폴리올 100 중량부, 물 0.5 내지 2 중량부, 트리에틸렌디아민 0.5 내지 1.5 중량부, 계면활성제 1 내지 2 중량부, 이소시아네이트 20 내지 40 중량부를 발포하여 제조되는 것이 바람직하다.More specifically, the polyurethane constituting the base layer 10 is 100 parts by weight of polyol, 0.5 to 2 parts by weight of water, 0.5 to 1.5 parts by weight of triethylenediamine, 1 to 2 parts by weight of surfactant, 20 to 40 parts by weight of isocyanate It is preferred that it is produced by foaming the part.

상기의 성분 중 트리에틸렌디아민은 상기의 성분이 반응하여 폴리우레탄으로 제조되는 과정에서 촉매의 역할을 하는데, 이소시아네이트의 중합반응이나 이소시아네이트(MDI, TDI)와 활성수소 화합물인 폴리올(Polyol)과의 반응에 이용되는 촉매는 그 Type이나 반응속도, 반응혼합물의 유동, Foam 등 생성물의 표면층, 코어의 형성에 관여하는 프로세스성 및 얻어지는 생성물의 물성에 영향을 주며, 제3급 아민에 해당하는 상기 트리에틸렌디아민은 일반적으로 염기도가 높을수록 또 아민질소의 전자대에 대한 입체장애가 없을수록 촉매기능이 향상되는데, 상기의 트리에틸렌디아민은 3급아민 중 활성화도(pKa:5.4)가 가장 높으며 반응성이 늦으므로 매트층을 형성하는 폴리우레탄의 완속회복조절을 쉽게 할 수 있다. 이와 같이 개시된 트리에틸렌디아민은 이소시아네이트와 폴리올의 인덱스 조절로 1차반응성이 조절된 반응물의 반응성을 2차 조절하여 완속회복 성능을 부여할 수 있다.Among the above components, triethylenediamine acts as a catalyst in the process of producing polyurethane by reacting the above components, and the polymerization reaction of isocyanates or reactions between isocyanates (MDI, TDI) and polyol, which is an active hydrogen compound. The catalyst used for this affects its type, reaction rate, flow of reaction mixture, surface layer of the product such as foam, processability involved in the formation of the core, and the properties of the resulting product, and the triethylene, which is a tertiary amine. Diamine generally improves the catalytic function as the basicity increases and there is no steric hindrance to the electron band of amine nitrogen.The triethylenediamine has the highest activation degree (pKa:5.4) among tertiary amines and has a slow reactivity. It is possible to easily control the slow recovery of the polyurethane forming the mat layer. The triethylenediamine disclosed as described above may impart a slow recovery performance by secondary control of the reactivity of a reactant whose primary reactivity is controlled by controlling the index of isocyanate and polyol.

상기와 같이 폴리우레탄은 폴리올 100 중량부, 물 0.5 내지 2 중량부, 트리에틸렌디아민 0.5 내지 1.5 중량부, 계면활성제 1 내지 2 중량부, 이소시아네이트 20 내지 40 중량부로 이루어진 혼합물은 100 내지 140초 동안 발포하여 기재층(10)으로 적용되는 것이 바람직하다.As described above, the polyurethane is a mixture consisting of 100 parts by weight of polyol, 0.5 to 2 parts by weight of water, 0.5 to 1.5 parts by weight of triethylenediamine, 1 to 2 parts by weight of surfactant, and 20 to 40 parts by weight of isocyanate foam for 100 to 140 seconds. It is preferable to apply as the base layer 10.

이때, 상기 계면활성제는 완속회복 성능을 나타내는 폴리우레탄을 제조하는데 사용되는 것이면 특별히 한정되지 않고 어떠한 것이든 사용가능하나 폴리실록산폴리알킬렌블록코폴리머로 이루어지는 것이 바람직하다.
At this time, the surfactant is not particularly limited as long as it is used to prepare a polyurethane exhibiting slow recovery performance, and any one may be used, but it is preferably made of a polysiloxane polyalkylene block copolymer.

상기 코팅층(20)은 상기 기재층(10)의 일면에 형성되며 실사인쇄층(21)이 형성되어 있는데, 코로나 방전처리된 10 내지 100㎛ 두께의 열가소성 폴리우레탄으로 이루어지는 것이 바람직하다.The coating layer 20 is formed on one side of the base layer 10 and the real print layer 21 is formed, and it is preferably made of a thermoplastic polyurethane having a thickness of 10 to 100 μm subjected to corona discharge treatment.

상기 열가소성 폴리우레탄은 유연성이 우수하면서도 내스크래치 성능과 투명성이 우수하여 상기 실사인쇄층(21)에 인쇄된 이미지가 선명하게 보이면서도 외력에 의해 실사인쇄층(21)이 손상되는 것을 방지할 수 있다.The thermoplastic polyurethane has excellent flexibility and excellent scratch resistance and transparency, so that while the image printed on the real print layer 21 is clearly visible, it is possible to prevent the real print layer 21 from being damaged by external force. .

또한, 상기와 같이 코로나 방전처리된 코팅층(20)은 일면에 실사인쇄층(21)을 형성하는 과정에서 코팅층(20)과 실사인쇄층(21)의 접착력이 향상될 수 있도록 하며, 실사인쇄층(21)이 코팅층(20)으로부터 쉽게 이격되지 않도록 하는 효과를 나타내는데, 상기 코팅층(20)의 두께가 10㎛ 미만이면 외력에 의해 코팅층이 쉽게 손상될 수 있으며, 상기 코팅층(20)의 두께가 100㎛를 초과하게 되면 코팅층(20)의 유연성이 저하되어 완층 매트를 접고 펴는 과정이 반복되면 코팅층(20)에 주름이 형성될 수 있다.In addition, the coating layer 20 treated with corona discharge as described above enables the adhesion between the coating layer 20 and the real print layer 21 to be improved in the process of forming the real print layer 21 on one side, and the real print layer (21) shows the effect of not being easily separated from the coating layer 20. If the thickness of the coating layer 20 is less than 10 μm, the coating layer may be easily damaged by external force, and the thickness of the coating layer 20 is 100 When it exceeds µm, the flexibility of the coating layer 20 decreases, and when the process of folding and unfolding the full-layer mat is repeated, wrinkles may be formed in the coating layer 20.

이때, 상기 코팅층(20)에 형성되는 실사인쇄층(21)은 코팅층(20)이 완충 매트의 가장 외측에 형성될 수 있도록 상기 기재층(20)과 상기 코팅층(20) 사이에 인쇄되는데, 상기 실사인쇄층(32)을 구성하는 성분은 합성수지 100 중량부, 희석제 50 내지 80 중량부, 습윤제 0.05 내지 1.5 중량부 및 경화제 0.01 내지 40 중량부를 혼합하여 이루어지며, 상기 합성수지는 폴리메틸메타아크릴레이트, 폴리우레탄, 폴리비닐알코올 및 에폭시로 이루어진 그룹에서 선택된 하나로 이루어지는 것이 바람직하다.At this time, the real print layer 21 formed on the coating layer 20 is printed between the base layer 20 and the coating layer 20 so that the coating layer 20 can be formed on the outermost side of the buffer mat. Components constituting the real print layer 32 are made by mixing 100 parts by weight of synthetic resin, 50 to 80 parts by weight of a diluent, 0.05 to 1.5 parts by weight of a wetting agent, and 0.01 to 40 parts by weight of a curing agent, and the synthetic resin is polymethyl methacrylate, It is preferably made of one selected from the group consisting of polyurethane, polyvinyl alcohol and epoxy.

상기 합성수지는 고형분의 함량이 20 내지 50%인 것이 바람직한데, 상기 합성수지의 고형분 함량이 20% 미만의 경우에는 조성물의 점도가 낮아져 실사 인쇄전 코팅층(20)에 도포시 도막의 형성이 곤란할 뿐만 아니라 건조 등의 제반 문제를 야기하고, 고형분의 함량이 50%를 초과하는 경우에는 점도가 높아져 도막을 형성하는 방법상 스프레이건 등을 이용할 수 없을 뿐만 아니라 수지용액의 뭉침 현상 및 부분 응고 현상이 발생하여 바람직하지 못하다.It is preferable that the synthetic resin has a solid content of 20 to 50%, but when the solid content of the synthetic resin is less than 20%, the viscosity of the composition is lowered, making it difficult to form a coating film when applied to the coating layer 20 before actual printing. It causes various problems such as drying, and if the solid content exceeds 50%, the viscosity increases, and a spray gun cannot be used for the method of forming a coating film, as well as agglomeration and partial solidification of the resin solution. It is not desirable.

또한, 상기 희석제는 50 내지 80 중량부가 함유되며 점도 조정에 의한 도포 성능 향상, 건조성 향상 등을 위하여 메틸알코올, 이소프로필알코올, 에틸아세테이트 및 톨루엔으로 이루어진 그룹에서 선택된 하나 이상을 사용할 수 있는데, 상기 희석제의 함량이 50 중량부 미만이면 희석제로서의 기본성능인 수지 조성물의 희석곤란으로 점도 및 인쇄적정성 제고를 위한 도포 성능과 건조성의 곤란이 초래되며, 희석제의 함량이 80 중량부 초과하는 경우에는 용해성, 점성이 떨어질 뿐만 아니라 실사인쇄층에 접착강도가 저하된다.In addition, the diluent contains 50 to 80 parts by weight, and at least one selected from the group consisting of methyl alcohol, isopropyl alcohol, ethyl acetate, and toluene may be used for improving coating performance by adjusting viscosity and improving drying properties. If the content of the diluent is less than 50 parts by weight, difficulty in dilution of the resin composition, which is the basic performance as a diluent, causes difficulty in coating performance and drying properties for improving viscosity and print suitability, and when the content of the diluent exceeds 80 parts by weight, solubility, Not only the viscosity is lowered, but also the adhesive strength to the real print layer is lowered.

또한, 상기 습윤제는 0.05 내지 1.5 중량부가 함유되는데, 기포방지 및 접착성능 강화를 목적으로 사용되는 것으로, 폴리에틸렌글리콜로 이루어지는데, 습윤제의 함량이 개시된 범위를 벗어나는 경우에는 기포방지 등의 습윤기능이 저하되어 인쇄 적성 및 접착성이 저하되어 바람직하지 못하다.In addition, the wetting agent contains 0.05 to 1.5 parts by weight, and is used for the purpose of preventing air bubbles and enhancing adhesive performance, and is made of polyethylene glycol.If the content of the wetting agent is outside the disclosed range, the wetting function such as anti-bubble is lowered. As a result, printability and adhesion are deteriorated, which is not preferable.

또한, 상기 경화제는 경화제 0.01 내지 40 중량부가 함유되며, 이소시아네이트계(Isocyanate), 멜라민포름알데히드계(Melamine-Formaldehyde), 폴리아미드아민(Polyamidamine)등을 사용할 수 있는데, 경화제의 함량이 0.01 중량부 미만인 경우에는 경화가 제대로 이루어지지 않아 실사인쇄층의 접착성이 저하되고, 경화제의 함량이 40 중량부를 초과하는 경우에는 과잉 경화로 인해 점도 불균형, 불안정으로 인쇄적성이 저하되는 문제점이 발생된다.In addition, the curing agent contains 0.01 to 40 parts by weight of a curing agent, and isocyanate-based (Isocyanate), melamine-formaldehyde-based (Melamine-Formaldehyde), polyamideamine (Polyamidamine), etc. can be used, and the content of the curing agent is less than 0.01 parts by weight. In this case, since the curing is not performed properly, the adhesiveness of the real print layer is deteriorated, and when the content of the curing agent exceeds 40 parts by weight, there is a problem that the printability is deteriorated due to viscosity imbalance and instability due to excessive curing.

상기의 성분으로 이루어지는 실사인쇄용 조성물은 코팅층(20)의 표면에 오염성분을 제거하고, 실사인쇄용 조성물의 접착력 유지를 위해 약 3 내지 50㎛의 두께로 균일하게 도포하며, 도포후에는 자연건조로 경화시킬 수 있으나 신속한 건조가 요구되는 경우에는 열경화 방식을 적용하여 110 내지 190℃의 온도에서 2m2기준 10 내지 300초간 건조시킨다. 실사인쇄용 조성물의 도포 두께가 3㎛미만인 경우에는 본 발명에 따른 수지 조성물이 나타내는 우수한 접착력 및 고해상도를 유지시킬 수 없으며, 실사인쇄용 조성물의 도포 두께가 50㎛를 초과하는 경우에는 오히려 자체적인 박리현상이 발생할 수 있다.The photorealistic printing composition consisting of the above components removes contaminants from the surface of the coating layer 20, is uniformly applied to a thickness of about 3-50㎛ to maintain the adhesive strength of the photorealistic printing composition, and cured by natural drying after application. However, if rapid drying is required, a thermal curing method is applied and dried for 10 to 300 seconds based on 2 m 2 at a temperature of 110 to 190°C. If the coating thickness of the real-life printing composition is less than 3 μm, the excellent adhesion and high resolution exhibited by the resin composition according to the present invention cannot be maintained. If the coating thickness of the real-life printing composition exceeds 50 μm, the self-release phenomenon is rather Can occur.

상기와 같은 실사인쇄용 조성물의 도포가 완료된 후에는 플로터 등을 이용하여 실사인쇄를 하게 되는데, 실사인쇄의 과정에서는 수성잉크와 유성잉크 및 자외선 경화형 잉크 등이 사용될 수 있다.After the application of the photorealistic composition is completed, photorealistic printing is performed using a plotter or the like. In the process of photorealistic printing, water-based ink, oil-based ink, and UV-curable ink may be used.

따라서, 개시된 실사인쇄층이 형성된 완충 매트는 실사인쇄층(21)이 형성된 코팅층(20)이 적용되어 사용중에 인쇄층의 이격이 발생하지 않고, 압력에 의해 눌린부분이 천천히 회복되는 성능을 나타낸다.
Accordingly, the disclosed buffer mat on which the actual printing layer is formed is applied with the coating layer 20 on which the actual printing layer 21 is formed, so that the separation of the printing layer does not occur during use, and the pressed portion is slowly recovered by pressure.
