본 발명은 장식시트용 염화비닐수지 조성물 및 이를 이용한 장식시트에 관한 것이다. 보다 자세하게는 장식시트의 기재층을 형성하는 착색 염화비닐수지 시트(또는 필름)에 그 성형성과 가공성을 용이하게 하기 위해 첨가되는 가소제가 점착제 층으로 이행(migration)되는 것을 억제시켜 점ㆍ접착력이 저하되는 문제를 방지할 수 있는 장식시트 및 그 성형(제조)용 염화비닐수지 조성물에 관한 것이다.The present invention relates to a vinyl chloride resin composition for a decorative sheet and a decorative sheet using the same. More specifically, the plasticizer added to the colored vinyl chloride resin sheet (or film) forming the base layer of the decorative sheet to facilitate its formability and processability is suppressed from being migrated to the pressure-sensitive adhesive layer, thereby reducing the viscosity and adhesive force. The present invention relates to a decorative sheet and a vinyl chloride resin composition for forming (manufacturing) thereof, which can prevent a problem from occurring.

일반적으로, 장식시트는 건축물의 내부 또는 외부 등에 원하는 문양을 부여하여 독특한 미감을 나타내기 위한 장식용도로 주로 사용되는 것이다. 이러한 시트는 일반 건축물의 표면이나, MDF, 집성목, 또는 파티클 보드와 같은 가공목재를 패널로 하여 이들의 표면에 부착되어 시트의 인쇄층에 인쇄된 각종 문양을 피가공 표면에 적용함으로 용이하게 원하는 문양을 나타낼 수 있게 하는 기능을 가진다. In general, the decorative sheet is mainly used for decorative purposes to give a unique pattern to the interior or exterior of the building to express a unique aesthetic. These sheets can be easily patterned by applying various patterns printed on the printed layer of the sheet by attaching them to the surface of a general building or processed wood such as MDF, aggregated wood, or particle board as a panel. It has a function that allows to display.

이러한 시트는 일반적으로 착색필름 층과, 상기 착색필름의 일면에 다양한 문양이 인쇄된 인쇄층 및 상기 인쇄층을 스크래치 등으로부터 보호하기 위한 투명 필름 층이 기본적인 시트의 층 구조로 형성(도1 참조)되고, 상기 착색필름 층의 아래(이면)에는 시트를 피 가공면에 접착하기 위한 점(접)착제층과 이 점(접)착제층을 보호하고 가공 시, 제거되는 이형지 층으로 구성되는 (도2 참조)것이 일반적이다. 이와 같이 구성되는 시트의 기재시트(또는 필름)로는 통상 착색 필름(시트))이 사용되며, 상기 착색필름으로는 일반적으로 신율, 인장, 인열 강도 등 기계적 물성이 강하고 작업성이 우수한 염화비닐수지 (Polyvinyl chloride;PVC)필름이 주로 사용되고 있다. 이들 PVC 필름은 그 성형성과 가공성을 양호하게 하기 위해 가소제가 필수적으로 첨가되며, 기존의 장식 시트에서 사용되는 가소제는 주로 프탈레이트계 가소제가 사용되어 왔다. In general, such a sheet is formed of a colored film layer, a printed layer having various patterns printed on one surface of the colored film, and a transparent film layer for protecting the printed layer from scratches, etc., in a basic sheet layer structure (see FIG. 1). And a bottom (back) adhesive layer for adhering the sheet to the surface to be processed and a release paper layer which protects the spot (glue) adhesive layer and is removed during processing, 2). As the base sheet (or film) of the sheet configured as described above, a colored film (sheet) is generally used. As the colored film, a vinyl chloride resin having excellent mechanical properties such as elongation, tensile strength and tear strength and excellent workability ( Polyvinyl chloride (PVC) film is mainly used. These PVC films are essentially added with a plasticizer in order to improve their formability and processability, and phthalate plasticizers have been mainly used as plasticizers used in existing decorative sheets.

도 1은 본 발명을 포함한 상기와 같이 구성되는 일반적인 장식 시트의 층 구조를 나타내는 장식시트의 단면도이다. 도 1에 도시된 층 구조에서 종래의 장식 시트에 있어서는 착색필름 층(1)이 PVC에 그 성형성과 가공성을 용이하게 하기 위해 첨가되는 프탈레이트계 가소제가 시간이 경과하면서 점착제 층(4)으로 이행(migration)되는 현상이 발생하고 이에 따라 점ㆍ접착력을 떨어뜨리는 문제가 있다. 1 is a cross-sectional view of a decorative sheet showing a layer structure of a general decorative sheet configured as described above including the present invention. In the conventional decorative sheet in the layer structure shown in Fig. 1, the phthalate-based plasticizer, in which the colored film layer 1 is added to PVC to facilitate its formability and processability, moves to the pressure-sensitive adhesive layer 4 over time. There is a problem that the migration (migration) occurs, thereby reducing the adhesive strength.

이에 따라 상기한 프탈레이트계 가소제의 이행을 막기 위한 방법으로서 프탈레이트계 가소제 대신 폴리에스테르(polyester)계 고분자 가소제를 사용하는 방법이 제시되었으나, 이 방법은 가소화 효율이 떨어지고 카렌다 가공 시 가공성이 좋지 않다는 단점이 있다. 또 다른 방법으로 PVC 시트의 하부에 프라이머 등 별도 처리층을 도입하는 방법이 제시되었는데, 예를 들어 대한민국 공개특허 제2005-0103990호는 도 3에 도시된 바와 같이, "PVC 시트(1)와 점착층(4) 사이에 이면처리 층(6)을 형성"하여 점착층으로의 가소제 전이를 방지하도록 하여 시간이 경과하여도 점착성능의 성능 변화가 적은 장식용 점착시트를 개시하고 있다. 그러나 상기한 방법은 통상의 장식용 점착시트지 제조 공정에 비해, 이면 처리제를 PVC 착색 필름 층 이면에 코팅하여 건조하는 공정이 추가되어 생산성이 나빠지고, 원재료 비용, 공정 비용 등 비용이 추가로 발생되는 단점이 있다.Accordingly, a method of using a polyester-based polymer plasticizer instead of a phthalate-based plasticizer has been proposed as a method for preventing the transition of the phthalate-based plasticizer. However, this method has a disadvantage in that the plasticization efficiency is poor and the workability during calendar processing is not good. There is this. As another method, a method of introducing a separate treatment layer such as a primer to the lower part of the PVC sheet has been proposed. For example, Korean Patent Laid-Open Publication No. 2005-0103990, as shown in FIG. The present invention discloses a decorative adhesive sheet having a backside treatment layer 6 formed between the layers 4 to prevent plasticizer transition to the adhesive layer so that the performance change of the adhesive performance is small over time. However, the above-described method has a disadvantage in that productivity is worsened by adding a process of coating the backing agent on the back side of the PVC colored film layer compared to the usual decorative adhesive sheet paper manufacturing process, resulting in additional costs such as raw material cost and process cost. There is this.

따라서, 본 발명자 등은 상기와 같이 별도의 층을 제공하지도 않고, 또한 가소화 효율과 가공성을 저하하지도 않으면서 종래의 문제점을 해결할 수 있는 장식시트에 대해 예의 연구하여 본 발명을 완성하였다.Therefore, the present inventors have completed the present invention by earnestly studying decorative sheets that can solve the conventional problems without providing a separate layer as described above and without degrading plasticization efficiency and processability.

본 발명의 목적은 우수한 점ㆍ접착력이 지속적으로 유지될 수 있는 장식시트 및 그 제조용 염화비닐수지 조성물을 제공하려는 것이다.An object of the present invention is to provide a decorative sheet and a vinyl chloride resin composition for producing the same that can maintain a good point, adhesive force continuously.

상기 본 발명의 목적은 장식시트 성형용 염화비닐수지 조성물에 에틸렌(ethylene)계 고분자를 함유시킴으로써 달성할 수 있다.The object of the present invention can be achieved by containing an ethylene-based polymer in the vinyl chloride resin composition for molding the decorative sheet.

상기 목적을 달성하기 위한 본 발명의 장식시트는 투명 필름 층, 인쇄층 및 착색 염화비닐수지 필름 층으로 이루어지는 장시시트에 있어서, 상기 착색 염화비닐수지 필름 층이 에틸렌(ethylene)계 고분자를 함유하는 염화비닐수지 조성물로 성형된 것을 특징으로 한다. The decorative sheet of the present invention for achieving the above object is a long sheet comprising a transparent film layer, a printing layer and a colored vinyl chloride resin film layer, wherein the colored vinyl chloride resin film layer contains ethylene (ethylene) -based polymer It is characterized by being molded into a vinyl resin composition.

본 발명의 상기 장식시트 성형용 염화비닐수지 조성물은 에틸렌(ethylene)계 고분자가 함유되는 것을 특징으로 한다.The vinyl chloride resin composition for forming the decorative sheet of the present invention is characterized in that it contains an ethylene (ethylene) -based polymer.

본 발명의 상기 장식시트 성형용 염화비닐수지 조성물은 가소제 및/또는 안정제, 활제 등 첨가제가 더 함유될 수 있다. The vinyl chloride resin composition for molding the decorative sheet of the present invention may further contain additives such as plasticizers and / or stabilizers, lubricants.

본 발명에 따른 상기 장식시트 성형용 염화비닐수지 조성물은 PVC 100 중량부에 대하여 에틸렌(ethylene)계 고분자가 5 내지 70 중량부로 조성되는 것이 바람직하다. 상기 에틸렌계 고분자는 PVC 100 중량부에 대해 5 중량부 미만으로 조성되면 가소제가 첨가되는 경우 가소제의 점착제 층으로의 이행을 방지하는 효과가 현저히 낮아 바람직하지 않고, 에틸렌계 고분자가 PVC 100 중량부에 대해 70 중량부를 초과하면 비용이 상승할 뿐 아니라 성형성과 가공성의 측면에서도 바람직하지 않다.The vinyl chloride resin composition for forming a decorative sheet according to the present invention is preferably composed of 5 to 70 parts by weight of an ethylene polymer based on 100 parts by weight of PVC. When the ethylene-based polymer is less than 5 parts by weight based on 100 parts by weight of PVC, the effect of preventing the transition of the plasticizer to the pressure-sensitive adhesive layer when the plasticizer is added is not preferable, and the ethylene-based polymer is contained in 100 parts by weight of PVC. If it exceeds 70 parts by weight, the cost not only rises, but is also undesirable in view of formability and processability.

본 발명에서 사용되는 염화비닐수지 조성물 중, 상기 염화비닐수지와 가소제, 안정제, 활제 등 첨가제는 일반적인 통상의 장식시트 성형용 염화비닐수지 및 첨가제와 동일한 것을 사용할 수 있다. Among the vinyl chloride resin compositions used in the present invention, additives such as the vinyl chloride resin, a plasticizer, a stabilizer, and a lubricant may be the same as those of general vinyl chloride resins and additives for general decorative sheet molding.

본 발명에서 사용되는 상기 에틸렌(ethylene)계 고분자는 예를 들면, 에틸렌/비닐아세테이트/카본 모녹사이드 (ethylene/vinyl acetate/carbon monoxide ;E/VA/CO) 코폴리머(copolymer), 에틸렌/노르말-부틸 아크릴레이트/카본모녹사이드(ethylene/n-buthyl acrylate/carbon monoxide ;E/nBA/CO) 코폴리머(copolymer), 에틸렌/노르말-부틸 아크릴레이트/글리시딜 메타크릴레이트 (ethylene/n-buthyl acrylate/glycidyl methacrylate;E/nBA/GMA) 코폴리머(copolymer) 등과 같은 수지 중에서 선택되는 1종 또는 2종 이상의 혼합물을 사용할 수 있다. The ethylene-based polymer used in the present invention is, for example, ethylene / vinyl acetate / carbon monoxide (ethylene / vinyl acetate / carbon monoxide (E / VA / CO) copolymer, ethylene / normal- Butyl acrylate / carbon monoxide (ethylene / n-buthyl acrylate / carbon monoxide; E / nBA / CO) copolymer, ethylene / normal-butyl acrylate / glycidyl methacrylate (ethylene / n-buthyl One or a mixture of two or more selected from resins such as acrylate / glycidyl methacrylate (E / nBA / GMA) copolymers may be used.

상기와 같이 구성되는 본 발명의 장식시트용 염화비닐수지 조성물은 PVC 수지와 잘 혼합(blending)되고, 유연성(flexibility)을 가지며 일반적인 프탈레이트계 가소제와 달리 표면으로 이행되지 않는 에틸렌계 고분자 수지를 일정 비율로 첨가함으로써 이를 사용한 장식시트는 에틸렌계 고분자 수지 및/또는 프탈레이트계 가소제가 점착제 층으로의 이행되는 것을 방지하며, 착색 필름 층의 가소제가 점착제 층으로 거의 이행되지 않아 시간이 경과하여도 시트의 물성을 저하시키지 않는 다. The vinyl chloride resin composition for decorative sheets of the present invention configured as described above is well blended with PVC resin, has flexibility, and has a certain ratio of ethylene-based polymer resin that does not migrate to the surface unlike general phthalate-based plasticizers. The decorative sheet using the same prevents the ethylene polymer resin and / or the phthalate-based plasticizer from transferring to the pressure-sensitive adhesive layer, and the plasticizer of the colored film layer hardly migrates to the pressure-sensitive adhesive layer, so that even if the time passes, Does not degrade.

이하, 본 발명을 실시예에 의해 보다 자세히 설명하지만, 본 발명이 이에 의해 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited thereto.
