본 발명은 인쇄 패턴과 엠보가 일치되어 입체감이 우수한 바닥재 및 그 제조방법에 관한 것으로서, 보다 상세하게는 다층구조의 바닥재에 있어서, 1차 인쇄층 또는 유색층 위에 특정 패턴의 엠보를 음각으로 형성시킨 후, 그 위에 인쇄 핀트를 맞추어 이중인쇄하므로써 인쇄 패턴과 엠보가 일치되어 입체감이 우수한 바닥재 및 그 제조방법에 관한 것이다.The present invention relates to a flooring material having excellent three-dimensional effect by matching a printed pattern with embossing, and more particularly, to a multi-layered flooring material, in which an emboss of a specific pattern is negatively formed on a primary printing layer or a colored layer. The present invention relates to a flooring material having excellent three-dimensional effect by matching a printing pattern and embossing by double-printing the printing focus thereon and a method of manufacturing the same.

근래, 소비자의 생활 수준과 주거생활에 요구되는 기본 요건들의 향상으로 인해, 바닥재는 단순히 바닥마감재로서의 역할뿐 아니라, 여러 가지 음이온, 항균기능, 전자파 차단 등 다양한 기능이 요구되며, 차별화된 색상과 패턴 등 디자인에 대한 요구 또한 크게 늘고 있다. In recent years, due to the improvement of the basic requirements for consumer's living standards and residential life, flooring is not only a floor finishing material, but also requires various functions such as various anions, antibacterial functions, and electromagnetic wave blocking. The demand for back design is also increasing.

PVC 바닥재의 경우, 가격이 싸고, 가공이 쉬우며, 시공이 편리하다는 점 이외에 여러 가지 디자인을 제품에 접목시킬 수 있다는 큰 장점을 가지고 있다. 하지만, 근래 들어 자연소재의 질감이나 이미지를 바닥재에 적용시키는 노력들이 커지고 있으나, 공지의 그라비아, 로터리스크린 또는 전사 인쇄방식 등으로 단순 평면 위에 잉크나 착색졸을 사용하여 여러 가지 도수의 색상을 혼합하는 기존의 방법들은 자연소재 질감을 표현할 수 있는 범위에 한계가 있어 입체감이나 사실감 면에서 크게 떨어지고 있다. In the case of PVC flooring, it is inexpensive, easy to process, and easy to install. However, in recent years, efforts have been made to apply a texture or image of a natural material to a flooring material. However, by using a known gravure, rotary screen, or transfer printing method, ink or coloring sol is mixed on a simple flat surface to mix various colors of frequency. Existing methods are limited in the range of expressing the texture of natural materials, which is greatly falling in terms of three-dimensional or realism.

이런 문제점들을 해결하고 자연소재의 질감을 재현하기 위하여, 그라비아 인쇄나 전사 인쇄로 인쇄 패턴을 부여하여 형성된 인쇄층을 바닥재의 한곳 이상에 위치시켜 인쇄효과를 표현한 후, 기계적 또는 화학적 방법에 의하여 요철무늬를 바닥재의 표면에 형성하거나 또는 내부에 인레이드(inlaid)시켜 입체감을 부여하는 방법이 통상적으로 사용되고 있으나, 인쇄 패턴과 통상의 요철이 일치하지 않아 자연소재 질감의 표현효과가 떨어지는 경향이 있다. In order to solve these problems and reproduce the texture of natural materials, the printing layer formed by giving a printing pattern by gravure printing or transfer printing is placed on one or more places of the flooring material to express the printing effect, and then the uneven pattern by mechanical or chemical method It is commonly used to form a surface on the surface of the flooring material or inlaid (inlaid) inside to give a three-dimensional feeling, but the printing pattern and the usual irregularities do not match, there is a tendency that the expression effect of the natural material texture is inferior.

인쇄 패턴과 엠보를 일치시키기 위한 방법(이하, 동조엠보)으로서, 인쇄층 하부에 발포층을 형성하고, 일정 도수의 인쇄 잉크에 발포배율을 낮출 수 있는 억제제나 발포배율을 늘릴 수 있는 촉진제를 첨가하여 인쇄한 후, 고온에서 발포시키므로써, 인쇄층 이면에 형성된 발포층의 발포배율 차이로 형성되는 음각과 양각의 차이를 이용하여 동조엠보를 형성하는 방법이 있으나, 이 방법은 화학적인 발포배율 차이로 형성되는 엠보의 형태가 한정적이고, 인위적이며, 발포온도나 작업속도 등의 차이로 인하여 엠보의 심도가 불균일한 단점이 있다. As a method for matching the printed pattern with the emboss (hereinafter referred to as a tuning emboss), a foam layer is formed below the printing layer, and an inhibitor capable of lowering the foaming factor or a promoter capable of increasing the foaming factor is added to the printing ink of a certain frequency. After printing by foaming at a high temperature, there is a method of forming a tuning emboss using the difference between the intaglio and the embossed formed by the difference in the foaming magnification of the foam layer formed on the back of the printing layer, but this method has a chemical foaming magnification difference The embossing is formed in a limited form, which is artificial, and there is a disadvantage that the depth of embossing is uneven due to differences in foaming temperature or working speed.

또 다른 동조엠보의 형성방법으로서, 인쇄 패턴과 동일한 엠보 패턴을 핀트를 맞추어서 인쇄 패턴과 엠보를 일치시키는 방법이 최근 들어 많이 사용되고 있으나, 이 방법은 인쇄 패턴과 엠보 패턴을 일치시키거나, 다양한 질감을 표현하는데 한계가 있고, 기존 인쇄에 추가적으로 설비가 필요하다는 단점이 있다. As another method of forming embossed embossing, a method of matching an embossed pattern with a printed pattern by matching the embossed pattern with a printed pattern has been widely used in recent years. There is a limit to the expression, there is a disadvantage that additional equipment is required for the existing printing.

이하에서는, 본 발명의 바람직한 실시형태에 대해 도면을 참조하여 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, preferred embodiment of this invention is described with reference to drawings.

도 2에 도시한 적층구조를 가지는 본 발명의 바닥재에 대해 설명하면 다음과 같다.Referring to the flooring of the present invention having a laminated structure shown in Figure 2 as follows.

경보행 바닥재의 일반적인 적층구조에 있어서, 기재층(1) 위에 발포 또는 비발포층(2)을 적층하고, 그라비아 인쇄나 로터리스크린 인쇄방식 등을 이용하여 동조엠보효과를 표현하고자 하는 색상을 전면으로 인쇄하거나, 전사필름으로 전사시켜 1차 인쇄층(7)을 형성하거나, 또는 기재층(1) 상부에 유색층(10)을 적층한 후, 그 위에 특정 패턴이 양각으로 표현된 롤을 이용하여 음각 엠보를 형성시킨다.In the general laminated structure of the warning line flooring material, the foamed or non-foamed layer 2 is laminated on the base material layer 1, and the color to express the tuning embossing effect is brought to the front using gravure printing or rotary screen printing. After printing, transferring to a transfer film to form a primary printing layer 7, or laminating the colored layer 10 on the base layer 1, using a roll embossed with a specific pattern thereon Form a negative emboss.

이때, 1차 인쇄층(7) 적층후 형성시키는 엠보의 심도는 0.1∼2.0mm가 바람직한데, 엠보의 심도가 0.1mm 미만일 경우, 2차 인쇄시 음각부분에 인쇄가 겹쳐서 인쇄 선명도가 떨어질 가능성이 있고, 엠보의 심도가 2.0mm를 초과할 경우, 냉각시 원단의 수축현상이 심하여 2차 인쇄시 표면이 나빠지거나, 기재층에 사용되는 유리섬유가 깨져 치수안정성이나 기계적 물성이 떨어지는 등의 문제가 생길 수 있으므로 바람직하지 않다. At this time, the depth of embossing formed after laminating the primary printed layer 7 is preferably 0.1 to 2.0 mm. If the depth of the embossing is less than 0.1 mm, the print clarity may be reduced due to the overlap of the intaglio portions during the second printing. If the depth of emboss exceeds 2.0mm, the shrinkage of the fabric is severe during cooling, so that the surface may be bad during the second printing, or the glass fiber used for the base layer may be broken, resulting in poor dimensional stability or mechanical properties. It is not preferable because it may occur.

1차 인쇄층(7)을 적층후 2차 인쇄층(8)을 형성시킬 때에는, 색감이 떨어지거나 원하는 색상의 표현이 어려울 수 있으므로, 우선 1도 인쇄시 은폐력이 뛰어난 백색 잉크를 전면으로 인쇄하여 건조한 후, 2∼5도까지의 원하는 색상과 패턴을 인쇄하는 이중인쇄방식으로 인쇄한 후, 그 위에 투명층(4)을 적층한다. 이 반제품에 하부발포층(5)을 적층하고 표면에 특수코팅층(6)을 처리하여 완제품을 제조한다.When the second printed layer 8 is formed after the first printed layer 7 is laminated, the color may be degraded or the desired color may be difficult to express. Therefore, the first printing layer 7 may be printed with white ink having excellent hiding power when printing first. After drying, printing is performed by the double-printing method which prints the desired color and pattern to 2-5 degree | times, and the transparent layer 4 is laminated | stacked on it. The lower foamed layer 5 is laminated on this semi-finished product, and a special coating layer 6 is treated on the surface to produce a finished product.
