입체 무늬를 가지는 벽지의 제조방법{The manufacturing method of wallpaper having solid pattern}The manufacturing method of wallpaper having solid pattern

본 발명은 입체무늬를 가지는 벽지의 제조방법에 관한 것으로, 보다 상세하기로는 간단한 공정으로 입체무늬를 부여할 수 있는 벽지의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a wallpaper having a three-dimensional pattern, and more particularly, to a method for manufacturing a wallpaper that can be provided with a three-dimensional pattern in a simple process.

일반적인 벽지는 평면적인 무늬를 가지만, 최근에는 장식성을 부여하기 위하여 입체적인 무늬를 가진 벽지의 제조방법에 관한 기술이 개발된 바 있다.The general wallpaper has a flat pattern, but in recent years, a technique for manufacturing a wallpaper having a three-dimensional pattern has been developed to give a decorative property.

입체감을 부여하기 위한 종래의 기술로는, 발포벽지에 그라비아 인쇄와 스크린 인쇄를 같이 행하여 풍부한 질감을 갖도록 한 한국특허등록 제1988-0001464호가 있으며, 인쇄부와 엠보싱부를 일치하게 하되 엠보싱부와 보강지 사이에 공간부가 형성되도록 한 한국특허등록 제1991-0003890호, 단계적인 다색 인쇄공정과 엠보싱공정을 결합하여 무늬의 입체감을 구현한 한국공개특허 제1993-0002087호, 표면에 인쇄층과 아크릴코팅층을 형성하고 입체 무늬 형상을 가진 상지의 하부 돌출면에 접착층을 형성하여 이 접착층과 평탄한 하지와 접착하여 상지와 하지 사이에 입체 공간부를 형성함으로써 입체감을 부여한 한국 등록실용신안 제20-02233382호 등이 있다.Conventional techniques for imparting a three-dimensional effect include Korean Patent Registration No. 1988-0001464, which performs a gravure print and screen print on a foamed wall paper to have a rich texture. The embossed portion and the reinforcement paper are made to match the printed portion and the embossed portion. Korea Patent Registration No. 1991-0003890, which allows a space to be formed between them, Korean Laid-Open Patent No. 193-0002087 which combines a stepwise multicolor printing process and an embossing process to realize a three-dimensional effect of a pattern, and a printing layer and an acrylic coating layer And the Korean Utility Model Model No. 20-02233382 which provides a three-dimensional effect by forming a three-dimensional space between the upper and lower limbs by forming an adhesive layer on the lower protruding surface of the upper limb having a three-dimensional pattern shape. .

그러나 상기 기술들은 엠보싱 후 동조인쇄, 다단계 인쇄 등과 같이 제조공정이 복잡하다는 문제점을 공통적으로 가지고 있다. '공간부'를 형성하는 기술들은 모두 상지와 하지의 접착부분이 분리될 수 있다는 문제점을 가지고 있다.However, these technologies have a common problem that the manufacturing process is complicated, such as co-printing, multi-step printing after embossing. All of the techniques for forming the 'space portion' have a problem that the adhesive portion of the upper and lower limbs can be separated.

본 발명은 상기한 바와 같은 문제점을 해결하기 위한 것으로, 제조공정이 극히 단순화된 입체 무늬를 가지는 벽지의 제조방법을 제공하는 것을 목적으로 한다. 본 발명의 다른 목적은 환경에 무해한 입체 무늬를 가지는 벽지의 제조방법을 제공하는 것이다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a method of manufacturing a wallpaper having a three-dimensional pattern in which the manufacturing process is extremely simplified. Another object of the present invention is to provide a method for producing a wallpaper having a three-dimensional pattern that is harmless to the environment.

도1은 요철이 형성된 벽지 원지가 종래의 유성도료에 의하여 코팅된 상태롤 나타내는 사진이고,1 is a photograph showing the state of the wallpaper base paper with irregularities formed by coating with a conventional oil-based paint,

도2는 요철이 형성된 벽지 원지가 본 발명에 의한 도료로 코팅된 상태를 나타내는 사진이다.2 is a photograph showing a state where the wallpaper base paper with the unevenness formed thereon is coated with the paint according to the present invention.

본 발명은 발포 또는 엠보싱된 벽지의 임계표면장력보다 높은 표면장력을 가지는 수성도료를 사용하여 벽지에 도포한 후 건조하는 것으로 구성된다.The present invention consists of coating on the wallpaper using an aqueous paint having a surface tension higher than the critical surface tension of the foamed or embossed wallpaper and then drying.

이하, 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail.

발포 또는 엠보싱된 벽지는 돌출부와 함입부로 형성되어 있으며, 이와 같은 형태로 그대로 사용되거나 또는 돌출부 혹은 함입부에 색상을 가진 도료를 코팅함으로써 색상을 부여함과 동시에 무늬의 입체감을 향상시키는 데 사용되기도 한다.Foamed or embossed wallpaper is formed of protrusions and recesses, and it is used as such, or it is used to enhance color and at the same time the pattern by giving a color coating to the protrusions or recesses. .

후자의 경우 돌출부 혹은 함입부에만 색상이 부여됨으로써 색상이 부여되지 않은 함입부 혹은 돌출부와 대비되어 무늬의 입체감이 향상되는 것은 사실이나 도료의 퍼짐성을 향상시키기 위하여 메틸에틸케톤, 톨루엔, 아세톤 등과 같은 유기용제가 사용되어야 하는 문제점이 있다.In the latter case, it is true that the color is applied only to the protrusions or indentations, so that the three-dimensional effect of the pattern is improved in contrast with the unindented indentations or protrusions. There is a problem that a solvent must be used.

예를 들면, 통상적으로 벽지로 사용되는 PVC 수지의 경우 임계표면장력이 약 40 dyne/cm(20℃ 기준)이며, 이러한 재질의 피도물에 도료를 도포하기 위해서는 표면장력이 36 dyne/cm 이하(20℃ 기준, 이하 동일함)인 상기 유기용제를 사용하여 도막의 퍼짐성을 향상시키는 방법을 사용하고 있는 것이다. 또한, 도료의 퍼짐성을 더욱 향상시키기 위하여 계면활성제가 통상 첨가된다.For example, in the case of PVC resin which is commonly used as wallpaper, the critical surface tension is about 40 dyne / cm (at 20 ° C), and the surface tension is 36 dyne / cm or less (20 The method of improving the spreadability of a coating film is used using the said organic solvent which is the same as that of (degreeC below). In addition, in order to further improve the spreadability of the paint, a surfactant is usually added.

그러나 상기 유기용제들은 인체에 좋지 않은 영향을 미치는 것이므로 작업환경을 열악하게 할뿐만 아니라, 이러한 유기용제가 사용되어 도포된 무늬는 입체감이 다소 부족하다는 문제점을 가지고 있다. 도1에서 보는 바와 같이 상기 기술에 의한 벽지는 요철이 형성된 벽지 원지의 돌출부에만 매우 선택적으로 도포되며, 함입부에는 거의 도포되지 아니한다.However, since the organic solvents have a bad effect on the human body, not only the working environment is poor, but the pattern applied by using the organic solvents has a problem that the three-dimensional feeling is insufficient. As shown in Fig. 1, the wallpaper according to the above technique is very selectively applied only to the protrusions of the wallpaper paper on which the unevenness is formed, and is hardly applied to the recesses.

본 발명에서는 이러한 문제점을 개선하여 보다 우수한 입체감과 색감을 얻기위하여 피도물인 벽지의 임계표면장력보다 높은 표면장력, 즉 45-70dyne/cm의 표면장력을 가지는 수성도료로 벽지의 돌출부를 도포한다. 물은 약 70dyne/cm 정도의 표면장력을 가지므로 물이 용제로 사용된 수성도료는 피도물인 벽지보다 높은 표면장력을 가지게 된다.In the present invention, the protrusion of the wallpaper is coated with an aqueous paint having a surface tension higher than that of the critical surface tension of the wallpaper, i.e., 45-70 dyne / cm, in order to improve the problem and to obtain more three-dimensional and color. Since water has a surface tension of about 70 dyne / cm, the water-based paint used as a solvent has a higher surface tension than wallpaper.

물에 첨가되는 수지는 폴리우레탄 수지, 아크릴 수지, 아크릴 에멀젼 등 물에 녹을 수 있는 수지라면 제한이 없다. 그리고 도료의 표면장력을 더욱 높이기 위하여 계면활성제는 첨가되지 아니한다.The resin added to the water is not limited as long as it is a resin that can be dissolved in water such as a polyurethane resin, an acrylic resin, and an acrylic emulsion. In order to further increase the surface tension of the paint, no surfactant is added.

물에 첨가되는 수지의 함량은 고형분을 기준으로 3-60중량%이며, 이 범위 미만의 경우에는 점도가 낮아 도포하는 데에 문제점이 있으며, 이 범위를 초과할 경우에는 점도가 너무 높아 코팅성 조절이 힘든 문제점이 있다. 고형분인 수지 외에 색상을 부여하기 위한 안료를 적당량 첨가할 수 있다.The content of the resin added to the water is 3-60% by weight based on the solid content, and if it is less than this range, there is a problem in applying a low viscosity, if it exceeds this range, the viscosity is too high to control the coating properties This is a tough problem. In addition to the resin which is a solid content, an appropriate amount of pigment for imparting color can be added.

고형분이 첨가되어 분산된 도료의 점도는 2-30000 cps/25℃ 정도가 되며, 이 범위를 초과할 경우에는 입체 무늬가 잘 나타나지 않고 인쇄 작업이 힘든 문제점이 있다.The viscosity of the paint dispersed by the addition of solid content is 2-30000 cps / 25 ℃ degree, if it exceeds this range, there is a problem that the three-dimensional pattern does not appear well and the print job is difficult.

본 발명은 상기와 같은 구성의 도료를 발포, 엠보싱처리 등으로 요철이 형성되어 있는 벽지에 그라비아 코팅한다. 코팅된 벽지는 종래의 기술처럼 돌출부에만 선택적으로 도포되는 것이 아니라, 함입부에 우선적으로 도포되며 돌출부에는 상대적으로 얇은 두께로 도포된다. 이로 인하여 형성된 무늬의 입체감은 극대화된다. 이와 같은 효과는 돌출부에 도포된 수성도료가 높은 표면장력으로 인하여 미세 방울을 형성하게 되며, 형성된 방울은 함입부로 떨어지게 되어 종래의 기술과는 달리함입부에 우선적으로 도포되는 것으로 추측된다.The present invention is a gravure coating on the wallpaper having the concavities and convexities formed by foaming, embossing or the like of the paint of the above configuration. The coated wallpaper is not preferentially applied only to the projections as in the prior art, but preferentially applied to the depressions and to the projections with a relatively thin thickness. This maximizes the three-dimensional appearance of the formed pattern. Such an effect is that the water-based paint applied to the protrusions form fine droplets due to the high surface tension, and the formed droplets fall to the indents, unlike the prior art, it is presumed to be preferentially applied to the indents.

도료가 도포된 벽지는 90-110℃의 온도에서 60-120초간 건조된다.The coated wallpaper is dried for 60-120 seconds at a temperature of 90-110 ° C.

본 발명의 실시예는 아래와 같다.An embodiment of the present invention is as follows.

(실시예)(Example)

고형분으로 폴리우레탄 수지 15중량%, 잉크 0.5 중량% 물에 첨가하여 잘 분산시켜 도료를 제조하였다. 제조된 도료의 임계 표면장력은 60 dyne/㎝이었으며, 이 도료를 요철이 형성된 미색 바탕의 벽지 원지(PVC 재질)에 그라비어 롤 코터로 처리하여 도포한 후 100℃에서 90초간 건조시켜 벽지를 제조하였다.Solids were added to 15% by weight of polyurethane resin and 0.5% by weight of ink to disperse well to prepare a paint. The critical surface tension of the prepared paint was 60 dyne / cm, and the paint was applied to an off-white wallpaper base paper (PVC material) coated with a gravure roll coater and dried at 100 ° C. for 90 seconds to prepare a wallpaper. .

얻어진 벽지는 도2에서 보는 바와 같이 함입부에 우선적으로 도포되며, 돌출부에는 상대적으로 얇은 두께로 도포되었다. 이로 인하여 종래의 기술에 의한 벽지보다 입체감이 우수하며, 은은하고 고급스러운 질감을 나타낸다.The wallpaper obtained was preferentially applied to the depressions as shown in Fig. 2, and was applied to the protrusions with a relatively thin thickness. For this reason, the three-dimensional effect is superior to the wallpaper according to the prior art, and exhibits a soft and luxurious texture.

이상의 실시예를 통하여 확인되는 바와 같이, 본 발명에 의한 벽지는 입체감이 우수하며, 은은하고 고급스러운 질감을 나타낼 뿐만 아니라, 유기용제가 사용되지 아니하므로 작업환경을 쾌적하게 하며 인쇄공정이 단순화되어 생산원가를 크게 낮출 수 있는 효과를 발휘한다.As confirmed through the above embodiment, the wallpaper according to the present invention is excellent in three-dimensional feeling, exhibits a soft and luxurious texture, and because no organic solvent is used, makes the working environment comfortable and the printing process is simplified, thus producing cost. The effect can be greatly lowered.
