Stabilizers and fillers can be used as long as it is commonly used in the art known in the art, especially stabilizers are mainly composed of 1: 1 barium hydroxide (Ba (OH) 2 ) and zinc oxide (ZnO). It was found that the most preferable result was the use of one.

표면 처리제 역시 공지된 것을 사용할 수 있으나 PVC와 아크릴 수지가 4 : 6 비율로 구성된 것을 주성분으로 하는 것을 사용하는 것이 가장 바람직하다.A surface treatment agent can also use a well-known thing, but it is most preferable to use what consists of PVC and an acrylic resin in a 4: 6 ratio as a main component.

본 발명의 전자파 흡수능을 갖는 벽지는 원지에 전자파 흡수제 용액을 전면 코팅하고 건조한 후 PVC 컴파운드(compound)를 일정 두께로 전면 도포한 다음 발포 처리하여 냉각하고 공지의 표면 처리제(PVC와 아크릴수지가 4 : 6 비율로 구성된 것을 주성분으로 하는 것이 바람직하다)를 도포한 후 인쇄, 엠보싱, 냉각을 행하는 것으로 특징지워 진다.The wallpaper having the electromagnetic wave absorbing ability of the present invention is completely coated with an electromagnetic wave absorber solution on a base paper, dried, and then completely coated with a PVC compound to a predetermined thickness, then cooled by foaming, and known surface treatment agents (PVC and acrylic resin 4: It is characterized by printing, embossing and cooling after applying the composition consisting of 6 ratios as a main component).

즉, 원지를 설비에 투입하고 전자파 흡수능을 부여하기 위하여 상술한 전자파 흡수제 용액을 원지상에 전면 도포하여 고온에서 열풍 건조한 다음, 전자파 흡수제가 도포된 원지에 상술한 PVC 컴파운드를 고온의 열풍을 이용하여 일정 두께로 발포시킨 후, 고온으로 발포된 제품을 냉각시킨다. 그 후 용도에 따른 표면 처리제(PVC와 아크릴수지가 4 : 6 비율로 구성된 것을 주성분으로 하는 것)를 도포하고 냉각된 제품을 디자인된 문양을 만들고자 하는 문양이 디자인된 로울러로 잉크를 제품에 전이한 다음, 일정한 온도로 제품에 열을 가하여 문양이 새겨진 롤(Roll)로 제품을 가압하여 엠보싱(Embossing)처리한 후, 제품을 냉각시킨다. 그 후 규정된 제품폭으로 양쪽의 귀퉁이 부분을 절단하고, 규정된 길이로 권취한 다음, 제품의 외형이 상하지 않도록 포장하여 완제품을 얻는다.In other words, in order to put the base paper into the equipment and to impart the electromagnetic wave absorbing ability, the above-mentioned electromagnetic wave absorber solution is completely coated on the base paper and dried by hot air at a high temperature, and then the above-described PVC compound is applied to the base paper coated with the electromagnetic wave absorber using high temperature hot air. After foaming to a certain thickness, the foamed product is cooled to a high temperature. After that, the surface treatment agent (PVC and acrylic resin is composed of 4: 6 ratio as the main ingredient) is applied, and the ink is transferred to the product by the roller designed to make the designed pattern of the cooled product. Next, the product is heated to a constant temperature to press the product with a roll engraved with a pattern (Embossing), and then the product is cooled. The corners on both sides are then cut to the specified product width, wound up to the specified length, and packaged so that the appearance of the product does not deteriorate.

전자파 흡수제 용액의 코팅 및 PVC 컴파운드의 코팅은 바코팅 등과 같이 본 발명이 속하는 기술분야에서 통상적으로 사용되는 코팅 장치를 이용하여 행하며, 특별히 한정되는 것은 아니지만 전자파 흡수제 코팅층은 전자파 흡수제의 코팅량이 15~40g/㎡이 되도록 하는 것이 효과적이고, PVC 컴파운드 코팅층은 PVC 컴파운드의 양이 100~300g/㎡이 되도록 하는 것이 바람직하다.The coating of the electromagnetic wave absorber solution and the coating of the PVC compound are carried out using a coating apparatus commonly used in the technical field to which the present invention belongs, such as bar coating, and the like. Although not particularly limited, the electromagnetic wave absorber coating layer has a coating amount of 15 to 40 g of the electromagnetic wave absorber. / M 2 is effective, and the PVC compound coating layer is preferably such that the amount of the PVC compound is 100 ~ 300g / m 2.

전자파 흡수제의 코팅시 전자파 흡수제를 아크릴 수지에 혼합하여 행할 수 있는데 이때 아크릴 수지 : 전자파 흡수제 = 100 : 30의 비율이 가장 효과적이었다. 전자파 흡수제의 코팅 후 건조시 온도 조건 및 PVC 컴파운드의 발포시 온도와 시간 등의 조건은 사용되는 수지의 종류에 따라, 목적하는 제품의 특성 등이 조건에 따라 변경될 수 있고 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자이면 용이하게 유추하여 변경할 수 있을 것이다.The coating of the electromagnetic wave absorber may be performed by mixing the electromagnetic wave absorber with an acrylic resin, wherein the ratio of acrylic resin: electromagnetic wave absorber = 100: 30 was most effective. The conditions such as temperature and drying conditions after coating of the electromagnetic wave absorber and the temperature and time of foaming of the PVC compound may be changed depending on the type of the resin used, the characteristics of the desired product, and the like. Those skilled in the art will be able to easily infer and change.

또한, 본 발명의 벽지는 PVC 컴파운드를 먼저 도포하여 발포하고 전자파 흡수제를 후에 도포하여 원지(1)/PVC 코팅층(3)/ 전자파 흡수제 코팅층(2)/ 표면 처리제 및 인쇄잉크층(4)의 구조로 제조될 수도 있다. 뿐만 아니라, PVC 컴파운드와 전자파 흡수제를 혼합한 용액을 도포하여 원지(1)/전자파 흡수제와 PVC 혼합 코팅층(5)/표면 처리제 및 인쇄잉크층(4)의 구조로 제조할 수도 있다. PVC 컴파운드와 전자파 흡수제를 혼합한 용액을 도포시에는 특별히 제한을 가하는 것은 아니지만 PVC 배합액에 전자파 흡수제를 5~7 중량%가 되도록 첨가하는 것이 도포 용이성, 발포 효율, 전자파 흡수 효과 등의 측면에서 바람직하였다.In addition, the wallpaper of the present invention, the PVC compound is first coated and foamed, and then the electromagnetic wave absorber is applied later to the structure of the base paper (1) / PVC coating layer (3) / electromagnetic wave absorber coating layer (2) / surface treatment agent and the printing ink layer (4) It may be prepared as. In addition, it is also possible to prepare a structure of the base paper (1) / electromagnetic wave absorber and the PVC mixed coating layer (5) / surface treatment agent and the printing ink layer (4) by applying a solution mixed with the PVC compound and the electromagnetic wave absorber. The application of a solution containing a mixture of PVC compound and an electromagnetic wave absorber is not particularly limited, but it is preferable to add an electromagnetic wave absorber to 5 to 7% by weight to the PVC compound in terms of ease of application, foaming efficiency and electromagnetic wave absorption effect.
