본 발명은 광고용 PVC시트 소재로 휨(Curling) 현상을 최소화하고 PVC시트에 표면 평활도를 높여 유성 도료 및 안료로 인쇄를 하거나 광고용 점착 시트지를 붙일 경 우 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 부직물 PVC시트이다. The present invention is to minimize the curling phenomenon of the PVC sheet material for advertising and to increase the surface smoothness on the PVC sheet to print with oil paints and pigments or when adhering the adhesive sheet paper for adhering the surface of the PVC sheet for even application and even adhesion 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. Nonwoven PVC sheet with increased smoothness.

기존 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.Existing 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.

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.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 발명은 상기와 같은 종래의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 휨(Curling)을 없애고 평활도를 높였으며 제조후 PVC시트가 외부온도 및 내부의 화학 변화에 변형이 없도록 물리적으로 제작한 것으로, 평활도가 우수한 PVC시트라는 것을 특징으로 하고 있다.The present invention is to solve the conventional problems as described above, the object of the present invention is to eliminate the bending (curling) and to increase the smoothness, and after manufacturing the PVC sheet physically manufactured so that there is no deformation in the external temperature and chemical changes of the interior It is characterized by the fact that it is a PVC sheet having excellent smoothness.

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. 롤러의 온도는 250도 이하로 해야하며, 압력은 12kg/㎠이하로 해야한다. 250도를 넘을 경우 연질 PVC및 부직물(PP부직포-폴리프로필렌 부직포, PET부직포-폴리에틸렌테레프탈레이트 부직포)(3)에 변형이 올 수 있다. 또한 압력이 높으면 접착력은 더 좋아질 수 있으나, 다공성을 가진 부직물(PP부직포-폴리프로필렌 부직포, PET부직포-폴리에틸렌테레프탈레이트 부직포)(3)에 공정을 거친후 냉각과정에서 부분적인 복원의 편차가 높아지는 문제가 있기에 500g/㎡이하의 부직물(PP부직포-폴리프로필렌 부직포, PET부직포-폴리에틸렌테레프탈레이트 부직포)(3)을 사용시에는 온도와 압력을 위와 같은 조건에서 이루어 져야 한다. 이러한 공정을 기본으로 부직물(PP부직포-폴리프로필렌 부직포, PET부직포-폴리에틸렌테레프탈레이트 부직포)(3)을 기준으로 단면 또는 양면에 연질PVC를 접합하여 제품을 다양화 할 수 있다.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. The temperature of the roller should be below 250 degrees and the pressure should be below 12kg / cm2. If it is more than 250 degrees, deformation may occur in soft PVC and nonwovens (PP nonwovens-polypropylene nonwovens, PET nonwovens-polyethylene terephthalate nonwovens) (3). In addition, the higher the pressure, the better the adhesion, but after the process of porous nonwoven fabric (PP nonwoven fabric-polypropylene nonwoven fabric, PET nonwoven fabric-polyethylene terephthalate nonwoven fabric) (3) increases the deviation of partial recovery in the cooling process Because of the problem, when using non-woven fabrics of less than 500g / ㎡ (PP nonwovens-polypropylene nonwovens, PET nonwovens-polyethylene terephthalate nonwovens) (3), the temperature and pressure should be made under the above conditions. 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.

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 발명하였다. 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.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) Invented by the selection and bonding by heat and pressure, the fabric was invented by giving a differentiation from the existing commercial PVC sheet that curling due to adhesive curing and irregularities of the fabric 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 한면 또는 양쪽에 접합된 연질PVC(1), 연질PVC(2)층의 변화에도 영향을 받지않는 지지층으로 연질PVC층의 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, 접착제를 사용하는 화학적 접합방식이 아닌 접착제없이 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 녹 은 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.Nonwovens (PP nonwoven fabric-polypropylene nonwoven fabric, PET nonwoven fabric-polyethylene terephthalate nonwoven fabric) (3) uses less than 500g / ㎡ and does not have its own deformation, soft PVC (1), soft PVC (2) bonded to one or both sides It is a support layer that is not affected by the change of the layer and is not affected by the hardening of the soft PVC layer. In addition, the bonding of the soft PVC (1) and the soft PVC (2) layer and the nonwoven fabric (PP nonwoven fabric-polypropylene nonwoven fabric, PET nonwoven fabric-polyethylene terephthalate nonwoven fabric) (3) did not use the adhesive of hardening. That is, the bonding by heat and pressure without the adhesive is not a chemical bonding method using an adhesive. 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 penetrates into the inside of the surface from inside 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.

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 발명에 따른 휨(Curling)이 없는 광고용 PVC시트는 기존의 접착제를 사용한 PVC시트보다 평활도가 우수하며 인쇄성 개선 및 광고용점착시트를 잘 붙게하였고, 용도별로 연질PVC에 색상을 내서 영사막으로 사용할 수 있다. 시간이 지남에 따라 생기는 외부적인 변형을 지지층 소재 및 가공방법을 적용하여 개선하였고 기존의 휨(Curling)이 발생하는 PVC시트의 문제점을 개선하여 인쇄 및 시트지 점착을 하는 모든 광고용 PVC시트 소재 및 영사막 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 the adhesive sheet for advertising, and colors the soft PVC for each use. Can be used as a projection screen. The external deformation that occurs over time is improved by applying the support layer material and processing method, and the PVC sheet material and projection film material for printing and sheet paper are improved by improving the problem of PVC sheet which causes the existing curling. Applicable to 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.
