본 발명은 친환경 수분공급타입 수성 점착벽지의 생산방법 및 그 점착벽지에 관한 것으로, 더욱 상세하게는 원지층의 하단에 점착제가 포함한 점착벽지를 형성하되, 원지에 부직포를 포함하고 수분을 포함할 수 있도록 하여 주름을 방지하고 물성을 높일 수 있으며, 적당한 수분함량을 유지함으로써, 점착을 시킨 후 수분을 흡수하여 발생하는 주름을 방지할 뿐만 아니라, 완전히 붙히기 전까지 수정이 가능하여 작업성이 좋은 친환경 수분공급타입 수성 점착벽지의 생산방법 및 그 점착벽지에 관한 것이다.The present invention relates to a method of producing an eco-friendly moisture supply type water-based adhesive wallpaper and to the adhesive wallpaper. More specifically, an adhesive wallpaper containing an adhesive is formed at the bottom of the base layer, but the base layer may contain a non-woven fabric and contain moisture.

일반적으로 벽지란 벽면을 보호하고 장식을 위해 바르는 종이로써, 초배를 한 후 그 위에 정배하고 종이나 천에 여러 가지 무늬를 인쇄한 것이 있으며, 처음부터 벽에 바르기 위해 짠 벽포나 염화비닐시트 등으로도 형성된다.In general, wallpaper is paper applied to protect and decorate a wall. It is first laid out and arranged on top, and various patterns are printed on paper or fabric. It is made of wallpaper or vinyl chloride sheets that are woven from the beginning to be applied to the wall. is also formed.
상기 종래의 벽지는 벽면에 부착되는 원지가 형성된 원지층이 형성되고, 상기 원지층의 상단에 합성수지코팅층이 형성되며, 상기 코팅층의 상단에는 무늬, 문양 및 색상을 형성하는 인쇄층으로 구성된다.The conventional wallpaper is formed by forming a base paper layer attached to the wall, a synthetic resin coating layer is formed on the top of the base layer, and a printing layer that forms patterns, patterns, and colors is formed on the top of the coating layer.
이와 같이 합성수지를 이용하여 코팅한 벽지를 합성수지 벽지 또는 실크벽지라 하고, 코팅하지 않은 벽지를 합지벽지라 한다.Wallpaper coated with synthetic resin in this way is called synthetic resin wallpaper or silk wallpaper, and uncoated wallpaper is called laminated wallpaper.
최근에는 실크벽지의 원지층의 하단에 점착제층을 형성하여 풀칠을 하지 않고도 도배가 가능하도록 형성된 점착벽지가 판매되고 있다.Recently, adhesive wallpaper is being sold in which an adhesive layer is formed at the bottom of the base layer of silk wallpaper so that it can be wallpapered without gluing.
그러나, 종래의 점착벽지는 도배 후에 원지층이 대기중의 수분을 흡수하여 팽창하기 때문에 부분적으로 주름이 발생하는 등의 문제점이 있었다.However, conventional adhesive wallpaper had problems such as partial wrinkles occurring because the base layer absorbed moisture in the air and expanded after wallpapering.
이러한 문제점을 해결하기 위해서, 대한민국 특허청 공개특허공보 제2008-0082312호에는 '초배지를 이용한 점착벽지'가 제공된다.In order to solve this problem, 'Adhesive wallpaper using adhesive wallpaper' is provided in Republic of Korea Patent Office Publication No. 2008-0082312.
상기 종래의 점착벽지는 벽면에 부착되는 원지층이 형성되고, 상기 원지층의 표면에는 코팅층이 형성되며, 상기 코팅층의 상단에 무늬 및 문양을 형성하는 인쇄층이 형성되고, 상기 원지층의 하단에는 점착제층이 형성되며, 상기 점착제층의 하단에는 이형지층이 형성되는 일반적인 점착벽지에 있어서, 상기 원지층의 원지 대신에 합성섬유에 천연펄프가 함유된 초배지가 사용된 초배지층이 형성되고, 상기 코팅층의 상단에는 투명잉크층이 형성되는 구성으로 형성된다.The conventional adhesive wallpaper is formed with a base layer attached to the wall, a coating layer is formed on the surface of the base layer, a printing layer forming patterns and patterns is formed on the top of the coating layer, and at the bottom of the base layer. In a typical adhesive wallpaper in which an adhesive layer is formed and a release layer is formed at the bottom of the adhesive layer, a backing layer containing a synthetic fiber and natural pulp is used instead of the base paper of the base layer, and the coating layer is formed. It is formed in such a way that a transparent ink layer is formed at the top of the .
또한, 종래의 점착벽지는 시공할 때 수정이 어려워서 벽면이나 벽지가 쉽게 손상되는 문제점이 있었다.In addition, conventional adhesive wallpaper was difficult to modify during construction, so there was a problem in that the wall surface or wallpaper was easily damaged.
상기한 문제점을 해결하고자, 대한민국 공개특허공보 제2003-0060086호에는 '표면벽지와 인체에 무해한 점착제층을 박리용 보호대지로 접속한 사이에 폴리에스탈 코팅층을 구성한 착탈이 용이한 인테리어 벽지를 개시하고 있다.In order to solve the above problems, Republic of Korea Patent Publication No. 2003-0060086 discloses an easily removable interior wallpaper composed of a polyester coating layer between the surface wallpaper and an adhesive layer harmless to the human body connected to a protective base for peeling. I'm doing it.
최근에는 벽지에 풀을 미리 바른 상태에서 벽지를 접어 낱개포장을 한 후 유통하는 경우도 있는데(일종의 '점착벽지'라 할 수 있다), 벽지에 풀이 칠해진 상태에서 유통될 경우 유통과정에서 풀이 상하게 되거나 굳게되어 사용할 수 없게 되는 등의 문제점이 있었다.Recently, there are cases where wallpaper is folded and individually packaged with glue applied to the wallpaper before distribution (it can be called a type of 'adhesive wallpaper'), but if it is distributed with glue applied to the wallpaper, the glue may get damaged during the distribution process. There were problems such as it hardening and becoming unusable.
이러한 문제점을 해결하기 위해서, 본원 발명자는 대한민국 특허청 등록특허공보 제2310140호에 '기능성 점착벽지 및 그 제조방법'을 개시한바 있는데, 제조공정중에 완전히 탈수된 원지층에 수분을 첨가하여 적당한 수분함량을 유지하도록 함으로써 점착을 시킨 후 수분을 흡수하여 발생하는 주름을 방지할 뿐만 아니라, 탈착 및 점착기능을 향상시켜 완전히 점착하기 전에 수정이 가능하도록 한 기술이 개시되어 있다.In order to solve this problem, the inventor of the present application disclosed 'Functional adhesive wallpaper and its manufacturing method' in Republic of Korea Intellectual Property Office Patent Publication No. 2310140. During the manufacturing process, moisture was added to the completely dehydrated base layer to maintain an appropriate moisture content. A technology has been disclosed that not only prevents wrinkles caused by moisture absorption after adhesion by maintaining the adhesive, but also improves desorption and adhesion functions to enable corrections before complete adhesion.
그러나, 종래의 기능성 점착벽지는 다음과 같은 문제점이 있었다.However, conventional functional adhesive wallpaper had the following problems.
(1) 원지층이 약하기 때문에 점착시 수정을 요할 때 당기게 되면 찢어지기 쉽다.(1) Because the base layer is weak, it is prone to tearing when pulled when correction is required during adhesion.
(2) 시공성을 높이기 위해서 탈착이 잘 되도록 형성하면 시공 후 벽지가 떨어지게 된다.(2) In order to improve constructability, if it is formed so that it can be easily attached and detached, the wallpaper will fall off after construction.
(3) 실크벽지의 표면에 벽지를 상단에 또 도포하면 떨어지기 쉽고, 쉽게 찢어지게 된다.(3) If wallpaper is applied on top of the surface of silk wallpaper, it will easily fall off and tear easily.
상기한 문제점을 해결하기 위해서, 본 발명은 펄프를 주성분으로 하는 원지층과, 상기 원지층의 하단에 도포되는 점착제층과, 상기 점착제층의 하단에 이형지층과, 상기 원지층의 상단에 합성수지코팅층과, 상기 코팅층의 상단에는 무늬, 문양 및 색상을 형성하는 인쇄층이 형성되는 일반적인 벽지에 있어서, In order to solve the above problems, the present invention includes a base paper layer containing pulp as a main ingredient, an adhesive layer applied to the bottom of the base paper layer, a release paper layer at the bottom of the adhesive layer, and a synthetic resin coating layer at the top of the base paper layer. And, in general wallpaper in which a printing layer forming patterns, patterns and colors is formed on the top of the coating layer,
상기 원지층에는 수분함량을 1~15%의 수분을 포함할 수 있도록 형성하되,The base layer is formed to contain moisture of 1 to 15%,
상기 원지층의 원지는 펄프 40~60중량%, 합성수지사 10~30중량% 및 코팅원료 10~30중량%, 첨가제 1~3 중량% 및 물 3~5 중량%를 혼합 후 가압하여 형성하는 것을 특징으로 한다.The base paper of the base layer is formed by mixing 40 to 60% by weight of pulp, 10 to 30% by weight of synthetic resin yarn, 10 to 30% by weight of coating raw materials, 1 to 3% by weight of additives, and 3 to 5% by weight of water and then pressing. It is characterized by
본 발명의 바람직한 실시예로 형성된 친환경 수분공급타입 수성 점착벽지의 생산방법 및 그 점착벽지에 의하면 다음과 같은 효과가 발생한다.According to the method for producing an eco-friendly moisture supply type water-based adhesive wallpaper formed in a preferred embodiment of the present invention and the adhesive wallpaper, the following effects occur.
(1) 원지층에 부직포가 포함되어 있어서 강도가 높아 점착시 수정을 요할 때 한쪽 방향으로 당겨도 잘 찢어지지 않아서 시공성이 좋다.(1) Because the base layer contains non-woven fabric, the strength is high, so it does not tear easily even when pulled in one direction when corrections are required during adhesion, so constructability is good.
(2) 점착제의 점착강도 및 점도를 적절히 유지함으로써 탈,부착이 용이하면서도 시공후 부착성이 매우 좋다.(2) By maintaining the adhesive strength and viscosity appropriately, it is easy to attach and detach, and has very good adhesion after construction.
(3) 점착제가 합성수지제이므로 합성수지제로 코팅된 실크벽지의 상면에 그대로 부착하여도 매우 잘 부착된다.(3) Since the adhesive is made of synthetic resin, it adheres very well even when attached directly to the top surface of silk wallpaper coated with synthetic resin.
도 1은 종래의 점착벽지의 시공후 주름이 발생한 사진Figure 1 is a photo of wrinkles occurring after construction of conventional adhesive wallpaper.

상기 원지층의 원지는 펄프 40~60중량%, 합성수지사 10~30중량% 및 코팅원료 10~30중량%를 혼합 후 가압하여 형성한다.The base paper of the base layer is formed by mixing 40 to 60% by weight of pulp, 10 to 30% by weight of synthetic resin yarn, and 10 to 30% by weight of coating raw materials and then pressing.
상기 셀룰로스(영어 : cellulose)는 수백에서 수천개의 D-포도당 단위체들이 β(1→4) 글리코사이드 결합으로 연결된 선형사슬이 중첩된 격자형의 다당류로, 화학식이 (C6H10O5)n 인 유기 화합물이다.The cellulose (English: cellulose) is a lattice-shaped polysaccharide composed of overlapping linear chains of hundreds to thousands of D-glucose units linked by β(1→4) glycosidic bonds, and is an organic compound with the chemical formula (C6H10O5)n.
상기 셀룰로스는 녹색식물, 다양한 형태의 조류 및 난균류의 1차 세포벽의 중요한 구조적인 구성요소로, 면섬유의 셀룰로스 함량은 90%이고, 목재의 셀룰로스 함량은 40~50%이며, 건조된 삼(hemp)의 셀룰로스 함량은 약 57%이다.The cellulose is an important structural component of the primary cell wall of green plants, various types of algae, and oomycetes. The cellulose content of cotton fiber is 90%, the cellulose content of wood is 40-50%, and dried hemp ) has a cellulose content of about 57%.
상기 원지층이 롤형태로 제조되고, 벽지가 제작될 당시에 다수개의 뜨거운 롤 또는 챔버를 지나기 때문에 수분함량이 거의 0%에 가깝게 건조된다.The base layer is manufactured in the form of a roll, and because it passes through multiple hot rolls or chambers when the wallpaper is manufactured, the moisture content is dried to close to 0%.
상기 원지층의 상단에는 합성수지코팅층이 형성되는데, 이는 인쇄가 잘 되도록 하기 위한 층으로 매우 얇게 코팅되어 원지층과 거의 일체화된다.A synthetic resin coating layer is formed on the top of the base paper layer. This layer is coated very thinly to ensure good printing and is almost integrated with the base paper layer.
상기 합성수지코팅층의 상단에는 인쇄층이 형성되는데, 일종의 층이라고 하기 보다는 원지층의 일부가 합성수지코팅층과 거의 일체화되어 문양이 인쇄된다. A printing layer is formed on top of the synthetic resin coating layer. Rather than being considered a type of layer, a part of the base layer is almost integrated with the synthetic resin coating layer and the pattern is printed.
상기 인쇄층의 상단에는 또 다시 합성수지제로 두껍게 코팅될 수 있는데, 이렇게 코팅된 벽지를 실크벽지라 한다.The top of the printed layer can be thickly coated with synthetic resin again, and wallpaper coated in this way is called silk wallpaper.
상기 원지층의 원지는 펄프 40~60중량%, 합성수지사 10~30중량% 및 코팅원료 10~30중량%를 혼합 후 가압하여 형성하되, 바람직하게는 펄프 55중량%, 합성수지사 20중량%, 코팅원료 20중량%, 첨가제 2중량%와 물3중량%를 혼합하여 형성하는 것이 바람직하다.The base paper of the base layer is formed by mixing 40 to 60% by weight of pulp, 10 to 30% by weight of synthetic resin yarn, and 10 to 30% by weight of coating raw materials and then pressing, preferably 55% by weight of pulp, 20% by weight of synthetic resin yarn, It is preferably formed by mixing 20% by weight of coating raw materials, 2% by weight of additives, and 3% by weight of water.
상기 코팅원료는 탄사칼슘 및 클레이(crey)를 사용하고, 코팅원료에 첨가제 및 물을 포함하여 원지를 생산한다.The coating raw materials use calcium carbonate and clay, and additives and water are included in the coating raw materials to produce the base paper.
상기 원지층은 수분을 1~15%를 포함하고 있으나, 벽지를 제조하는 공정 전체에서 원지층에 많은 열을 가하게 되어, 이러한 수분이 거의 0%에 달하게 된다.The base layer contains 1 to 15% of moisture, but as a lot of heat is applied to the base layer throughout the wallpaper manufacturing process, this moisture reaches almost 0%.
상기 원지층이 수분함량을 유지한채 건조되어야 주름이 발생하지 않고 팽팽하게 잘 부착된다.The base layer must be dried while maintaining its moisture content so that it is tightly attached without wrinkles occurring.
그런데, 종래의 점착벽지들이 이러한 점을 간과하여 원지층에 수분을 가하지 않고 점착제만을 도포하여 유통하고 있는데, 시공 후에 공기중으로부터 원지층이 수분재흡수가 이루어짐으로써 늘어나게 되어 도 1과 같이 주름이 발생하게 된다.However, conventional adhesive wallpapers overlook this point and are distributed by applying only an adhesive without adding moisture to the base layer. After construction, the base layer reabsorbs moisture from the air and stretches, causing wrinkles as shown in Figure 1. I do it.
본 발명은 벽지제조공정중 수분주입공정을 형성하여 원지층의 수분함량을 1~15%가 되도록 형성한다.The present invention forms a moisture injection process during the wallpaper manufacturing process so that the moisture content of the base layer is 1 to 15%.
즉, 벽지제조공정의 마지막 단계에서 수분주입공정을 수행하여 원지층에 적절한 수분을 유지함으로써 벽지 시공후 수분재흡수가 이루어지지 않도록 한다.In other words, a moisture injection process is performed at the last stage of the wallpaper manufacturing process to maintain appropriate moisture in the base layer to prevent moisture reabsorption after wallpaper construction.
상기 원지층의 하단에 형성되는 점착제층은 탈,부착이 용이하면서도 건조되었을 때 완벽하게 점착이 이루어질 수 있도록 형성된다.The adhesive layer formed at the bottom of the base layer is formed so that it is easy to attach and detach, and can adhere perfectly when dried.
상기 점착제층은 물 100중량%당 아크릴코폴리머(ACRIL CO POLYMER) 50~60중량%를 혼합하여 형성한다.The adhesive layer is formed by mixing 50 to 60% by weight of acrylic copolymer (ACRIL CO POLYMER) per 100% by weight of water.
상기 점착제층은 4000 내지 7000 cPs(센티포아즈)의 점도를 갖도록 형성되는데 바람직하게는 6000 cPs가 가장 좋은 점도이다.The adhesive layer is formed to have a viscosity of 4000 to 7000 cPs (centipoise), with 6000 cPs being the best viscosity.
상기 점착제층의 점도의 크기는 벽지 시공시 부착후 탈착, 재부착시에 적절한 힘으로 가능하도록 형성되는 최적의 수치한정이다.The size of the viscosity of the adhesive layer is the optimal numerical limit to enable appropriate force when attached, detached, and reattached during wallpaper construction.
상기 점착제층의 두께는 20~100㎛인 것이 적당하고, 이러한 수치한정은 벽면에 탈, 부착할 때 이탈되는 정도까지를 감안한 두께이다.The appropriate thickness of the adhesive layer is 20 to 100㎛, and this numerical limit is a thickness that takes into account the degree of separation when detaching or attaching to the wall.
상기 점착제층의 두께가 20㎛ 미만인 경우에는 충분한 점착성을 발휘하기 어렵고, 100㎛를 초과할 경우에는 시공이 잘 안되기 때문에 시공후 불량발생율이 높아진다.If the thickness of the adhesive layer is less than 20㎛, it is difficult to demonstrate sufficient adhesiveness, and if it exceeds 100㎛, construction is difficult and the defect occurrence rate after construction increases.

상기 이형지도포단계에서 사용되는 이형지는 70g 단면종이를 사용하여 형성한다.The release paper used in the release paper application step is formed using 70g single-sided paper.
상기 원지는 롤형태로 감겨서 있고, 코팅롤러사이를 통과할 때 상면이 코팅된다.The base paper is wound in a roll shape, and the upper surface is coated when it passes between coating rollers.
이때, 코팅층형성단계에서 열과 압력이 가해지고, 원지의 수분이 배출되어 건조된다. At this time, heat and pressure are applied in the coating layer formation step, and moisture from the base paper is discharged and dried.
상기 코팅층형성단계에는 엠보를 형성하는 단계를 포함할 수 있는데, 문양이 양,음각으로 형성된 코팅롤러사이를 통과시키는 과정으로 이 과정에서도 열을 가하게 된다.The coating layer forming step may include forming an emboss, a process in which the pattern passes between positive and negative coating rollers, and heat is also applied in this process.

상기 수분공급단계의 수분챔버에는 다수개의 노즐이 형성되고, 벽지의 원지에 수분을 분사할 수 있도록 형성된다.A plurality of nozzles are formed in the moisture chamber in the moisture supply step, and are formed to spray moisture onto the base paper of the wallpaper.
상기 이형지도포단계는 바트에 형성되는 점착제를 롤러에 묻혀서 회전시키면서 이형지의 일면에 점착제를 도포하는 단계이다.The release application step is a step of applying the adhesive formed on the bat to one side of the release paper while applying the adhesive to the roller and rotating it.
상기 이형지도포단계는 케스트코팅, 콤마코팅, 마이크로그라비아 및 슬롯다이코팅 등을 이용하여 이형지의 일면에 점착제를 도포할 수 있다.In the release coating step, an adhesive may be applied to one side of the release paper using cast coating, comma coating, microgravure, and slot die coating.
상기 점착제는 물 100중량%당 아크릴코폴리머(ACRYLIC CO POLYMER) 50~60중량%와 유화제 0.5~1중량%를 혼합하여 형성한다.The adhesive is formed by mixing 50-60% by weight of acrylic copolymer (ACRYLIC CO POLYMER) and 0.5-1% by weight of emulsifier per 100% by weight of water.
상기 점착제의 점착강도는 실크벽지 위에 부착한 상태에서 350 ~ 1,000kg/25mm 의 범위에 있는 것이 가장 적절하다.The most appropriate adhesive strength of the adhesive is in the range of 350 to 1,000 kg/25 mm when attached to silk wallpaper.
상기 점착강도가 1.000kg/25mm 이상되면 벽지가 분리되어 점착이 불가능하게 된다.If the adhesive strength exceeds 1.000kg/25mm, the wallpaper separates and adhesion becomes impossible.
