본 고안은 광고용 PVC시트 소재로 휨(Curling) 현상을 최소화하고 PVC시트에 표면 평활도를 높여 유성 도료 및 안료로 인쇄를 하거나 광고용 점착 시트지를 붙일 경우 표면의 고른 도포와 고른 점착을 위해 PVC시트 표면을 평평하게 하였다. 연질 PVC(1)와 연질 PVC (2)를 지지하는 부분의 소재를 화학적변화가 없고 매우 안정적인 부직물(PP부직포-폴리프로필렌 부직포, PET부직포-폴리에틸렌테레프탈레이트 부직포)(3)을 사용하여 휨을 1차적으로 방지하였다. 또한 부직물(PP부직포-폴리프로필렌 부직포, PET부직포-폴리에틸렌테레프탈레이트 부직포)(3)과 연질 PVC(1), 연질 PVC(2)를 하나의 시트로 만들기 위해 경화가 심한 접착제를 사용하지 않고 다공성을 가진 부직물(PP부직포-폴리프로필렌 부직포, PET부직포-폴리에틸렌테레프탈레이트 부직포)(3)에 연질PVC를 열과 압력으로 융착하는 방법으로 물리적인 접착력이 우수하며 휨(Curling)현상을 근본적으로 제거하여 평활도를 높인 광고용 PVC시트이다. This design minimizes curling and increases surface smoothness on PVC sheets and prints with oil paints and pigments, or when adhering adhesive sheets for advertisement. Leveled. The material of the parts supporting the soft PVC (1) and the soft PVC (2) was warped by using a non-chemically stable nonwoven fabric (PP nonwoven fabric-polypropylene nonwoven fabric, PET nonwoven fabric-polyethylene terephthalate nonwoven fabric) (3). Prevented it sequentially. Also, it is porous without using hard adhesive to make nonwoven fabric (PP nonwoven fabric-polypropylene nonwoven fabric, PET nonwoven fabric-polyethylene terephthalate nonwoven fabric) (3), soft PVC (1), soft PVC (2) into one sheet. (3) It is a method of fusion of flexible PVC with heat and pressure to nonwovens (PP nonwoven fabric-polypropylene nonwoven fabric, PET nonwoven fabric-polyethylene terephthalate nonwoven fabric) and has excellent physical adhesive strength and fundamentally eliminates curling phenomenon. PVC sheet for advertisement with increased smoothness.

기존 광고용 PVC시트는 접착제를 사용하여 PVC와 필름을 붙이거나, 폴리에스터 직물에 PVC를 접착하는 방법으로 제조하였다. 접착제를 사용하면 화학적 변화로 인한 경화가 진행되어 PVC시트에 변형이 생기고 또한, 폴리에스터 직물을 사용하여 연질 PVC를 접착시에는 주변온도에 따라 수축변화가 심한 연질 PVC가 불안정한 폴리에스터 직물에 영향을 주어 휨(Curling)을 발생시킨다. 또한 폴리에스터 직물은 연질 PVC 표면에 굴곡을 만들어 원단 표면을 고르게 하지 못한다. 이런 문제가 발생되므로 문제를 원천적으로 없애기 위해 연질PVC와 융착하는 원단소재를 부직물(PP부직포-폴리프로필렌 부직포, PET부직포-폴리에틸렌테레프탈레이트 부직포)(3)을 사용하였으며, 열과 균일한 압력으로 접합을 하여 PVC시트 전체에 안정성을 주어 휨(Curling)이 발생하지 않도록 만들었다.Existing commercial PVC sheet was manufactured by attaching PVC and film using adhesive or by attaching PVC to polyester fabric. When adhesive is used, the hardening is progressed due to chemical change, which causes deformation of the PVC sheet. In addition, when soft PVC is bonded using polyester fabric, soft PVC, which has a large shrinkage change depending on the ambient temperature, may affect the unstable polyester fabric. Subject to curling. In addition, polyester fabrics create bends on the soft PVC surface, making the fabric surface uneven. In order to eliminate this problem, a nonwoven fabric (PP nonwoven fabric-polypropylene nonwoven fabric, PET nonwoven fabric-polyethylene terephthalate nonwoven fabric) (3) was used as a fabric material that is fused with a soft PVC. By giving stability to the entire PVC sheet was made so that bending (Curling) does not occur.

본 고안은 상기와 같은 종래의 문제점을 해결하기 위한 것으로서, 본 고안의 목적은 휨(Curling)을 없애고 평활도를 높였으며 PVC시트가 외부 및 내부의 환경 변화에 전혀 변형이 없도록 물리적으로 제작한, 평활도가 우수한 광고용 PVC시트라는 것을 특징으로 하고 있다. 부직물(PP부직포-폴리프로필렌 부직포, PET부직포-폴리에틸렌테레프탈레이트 부직포)(3)과 연질PVC층은 접착제에 의한 접착이 아닌 열과 압력에 의한 접착, 즉, 열롤러(Hot Melting Roller)를 이용한 카렌더(Calender)공정으로 접합을 한다. 이러한 공정을 기본으로 부직물(PP부직포-폴리프로필렌 부직포, PET부직포-폴리에틸렌테레프탈레이트 부직포)(3)을 기준으로 단면 또는 양면에 연질PVC를 접합하여 제품을 다양화 할 수 있다. 이와 같이 기존의 불규칙한 직물구조를 가진 폴리에스터 직물 및 접착제를 이용한 화학적 제조방법은 PVC시트에 변형을 주나 연질 PVC의 변형에 전혀 영향을 받지않는 부직물(PP부직포-폴리프로필렌 부직포, PET부직포-폴리에틸렌테레프탈레이트 부직포)(3) 선택과 열과 압력에 의한 접합으로 한번 만들어진 원단은 시간이 지남에 따라 접착제 경화 및 원단의 불규칙성으로 휨(Curling)이 생기는 기존의 광고용 PVC시트와 차별화를 주어 고안하였다. 휨(Curling)현상을 제거하기 위해 경화가 심한 접착제로 붙이는 방법을 사용하지 않았으며, 직물 대신 부직물(PP부직포-폴리프로필렌 부직포, PET부직포-폴리에틸렌테레프탈레이트 부직포)(3)을 사용하였고 균일하게 열과 압력으로 접합한 것이 본 제품의 기술적 특징이다.The present invention is to solve the conventional problems as described above, the purpose of the present invention is to eliminate the bending (curling) and to increase the smoothness, the PVC sheet is physically produced so that there is no deformation at all in the external and internal environmental changes, smoothness Is characterized in that the excellent PVC sheet for advertising. The nonwoven fabric (PP nonwoven fabric-polypropylene nonwoven fabric, PET nonwoven fabric-polyethylene terephthalate nonwoven fabric) (3) and the soft PVC layer are bonded by heat and pressure, not by an adhesive, that is, a calender using a hot melting roller. Joining is done by (Calender) process. Based on this process, nonwoven fabrics (PP nonwoven fabric-polypropylene nonwoven fabric, PET nonwoven fabric-polyethylene terephthalate nonwoven fabric) (3) based on the flexible PVC bonded to one or both sides can be diversified products. As such, the conventional chemical fabrication method using polyester fabrics and adhesives having an irregular fabric structure is a non-woven fabric which does not change the PVC sheet but is not affected by the deformation of the soft PVC (PP nonwoven fabric-polypropylene nonwoven fabric, PET nonwoven fabric-polyethylene Terephthalate non-woven fabric) (3) The fabric made by selection and bonding by heat and pressure is designed to differentiate it from the existing commercial PVC sheet that curling occurs due to adhesive curing and fabric irregularities over time. In order to eliminate curling, a hardened adhesive method was not used, and a nonwoven fabric (PP nonwoven fabric-polypropylene nonwoven fabric, PET nonwoven fabric-polyethylene terephthalate nonwoven fabric) (3) was used instead of the woven fabric. Bonding with heat and pressure is a technical feature of this product.

도1은 본 발명에서 각각의 특성별 층분리에 관한 사시도이다.1 is a perspective view of the layer separation for each characteristic in the present invention.

부직물(PP부직포-폴리프로필렌 부직포, PET부직포-폴리에틸렌테레프탈레이트 부직포)(3)은 500g/㎡이하를 사용하며 자체의 변형이 없으므로 양쪽에 접합된 연질 PVC(1), 연질PVC(2)층의 변화에도 영향을 받지않는 지지층으로 연질 PVC(1), 연질 PVC(2)층의 경화에 따른 영향도 받지않는 것이 특징이다. 또한, 연질PVC(1) 및 연질PVC(2)층과 부직물(PP부직포-폴리프로필렌 부직포, PET부직포-폴리에틸렌테레프탈레이트 부직포)(3)의 접합은 경화가 심한 접착제를 사용하지 않았다 즉, 화학적 접합방식이 아닌 물리적 방식인 카렌더(Calender)공정으로 열과 압력에 의한 접합을 하였다. 일반적으로 엔지니어링플라스틱중 PP(폴리프로필렌) 및 PET(폴리에틸렌테레프탈레이트)은 표면접착력이 약하지만 부직물(PP부직포-폴리프로필렌 부직포, PET부직포-폴리에틸렌테레프탈레이트 부직포)(3)은 표면 및 내부에 다공성을 가지고 있기에 연질PVC가 녹은 상태에서 표면외에 내부까지 침투되어 결합되기에 접착력이 우수하다. 연질PVC(1) 및 연질PVC(2)층 두께가 0.5mm를 넘지 않으며, 연질PVC층을 최대한으로 얇게하더라도 평활도 및 접합이 우수하며 또한 제품의 다양화 및 원가절감을 할 수 있다. 연질PVC(1) 및 연질PVC(2)층과 부직물(PP부직포-폴리프로필렌 부직포, PET부직포-폴리에틸렌테레프탈레이트 부직포)(3)사이에 Black층을 만들어 은폐력을 높여 실사인쇄후에 뒷면에서 인쇄된 문구가 비추는 것을 방지할 수 도 있다. 연질PVC층(1)은 광고용 실사 인쇄시 인쇄가 잘되며 또한 광고용 점착 시트지를 붙일 때도 접착력이 좋으나 이렇게 평활도가 우수하게 제작된 원단을 사용 시에는 인쇄의 고룬 분포로인해 선명도를 높일 수 있고, 점착시트 부착시 굴곡이 없기에 공기가 들어가지 못하며 접착력을 극대화 시킬 수 있다. Nonwoven fabric (PP nonwoven fabric-polypropylene nonwoven fabric, PET nonwoven fabric-polyethylene terephthalate nonwoven fabric) (3) uses less than 500 g / m 2 and has no deformation of its own, so that soft PVC (1) and soft PVC (2) layers bonded to both sides It is not affected by the change of the soft PVC (1), it is characterized by not being affected by the curing of the soft PVC (2) layer. In addition, the bonding of the soft PVC (1) and soft PVC (2) layers with the nonwoven fabric (PP nonwoven fabric-polypropylene nonwoven fabric, PET nonwoven fabric-polyethylene terephthalate nonwoven fabric) (3) did not use a hardened adhesive, that is, chemical Bonding by heat and pressure was performed by the calender process, which is not a bonding method but a physical method. Generally, PP (polypropylene) and PET (polyethylene terephthalate) in engineering plastics have a weak surface adhesion, but nonwoven fabrics (PP nonwoven fabric-polypropylene nonwoven fabric, PET nonwoven fabric-polyethylene terephthalate nonwoven fabric) (3) are porous on the surface and inside. Since it has a soft PVC, the adhesiveness is excellent because it is penetrated to the inside of the surface in the melted state. The thickness of the soft PVC (1) and soft PVC (2) layer does not exceed 0.5mm, and even if the soft PVC layer is as thin as possible, the smoothness and bonding are excellent, and the product can be diversified and the cost can be reduced. Soft PVC (1) and Soft PVC (2) layer and nonwoven fabric (PP nonwoven fabric-polypropylene nonwoven fabric, PET nonwoven fabric-polyethylene terephthalate nonwoven fabric) (3) to create a black layer to increase the hiding power printed on the back after the actual printing You can also prevent the phrase from shining. The soft PVC layer (1) prints well when printing for live-action advertising, and also has good adhesion when adhering adhesive sheets, but when using fabrics made with excellent smoothness, the sharpness can be increased due to the distribution of printing. Since there is no bending when attaching the sheet, air cannot enter and maximize adhesion.

부직물(PP부직포-폴리프로필렌 부직포, PET부직포-폴리에틸렌테레프탈레이트 부직포)(3)은 기존의 폴리에스터 직물보다 화학적, 물리적으로 매우 안정적인이며 PVC 원단 지지층이다.Nonwovens (PP nonwovens-polypropylene nonwovens, PET nonwovens-polyethylene terephthalate nonwovens) (3) are chemically and physically more stable than conventional polyester fabrics and are PVC fabric support layers.

상기 언급한 바와 같이 본 고안에 따른 휨(Curling)이 없는 광고용 PVC시트는 기존의 접착제를 사용한 PVC시트보다 평활도가 우수하며 인쇄성 개선 및 광고용점착시트를 잘 붙게하였고, 시간이 지남에 따라 생기는 외부적인 변형을 지지층 소재 및 가공방법을 적용하여 개선하였다. 기존의 휨(Curling)이 발생하는 광고용 PVC시트의 문제점을 개선하여 인쇄 및 시트지 점착을 하는 모든 광고용 PVC시트 소재에 적용할 수 있다. 비록 본 발명이 상기 언급된 바람직한 실시 예와 관련하여 설명되어졌지만, 발명의 요지와 범위로부터 벗어남이 없이 광고용 PVC시트 형상의 제품군에 다양하게 적용을 하는 것이 가능하다.As mentioned above, the PVC sheet for advertising without curling according to the present invention has better smoothness than the PVC sheet using the conventional adhesive, improves printability and adheres to the adhesive sheet for advertisement, and the external appearance occurs over time. The deformation was improved by applying the support layer material and processing method. It can be applied to all the advertising PVC sheet material for printing and sheet adhesion by improving the problem of the advertising PVC sheet which the existing curling occurs. Although the present invention has been described in connection with the above-mentioned preferred embodiment, it is possible to apply variously to the product line of the PVC sheet shape for advertisement without departing from the spirit and scope of the invention.
