The following embodiments are provided as examples to ensure that the spirit of the present invention can be fully conveyed to those skilled in the art. Therefore, the present invention is not limited to the embodiments described below, but may be embodied in other forms. In the drawings, the width, length, thickness, etc. of the components may be exaggerated for convenience. Like numbers refer to like elements throughout.

본 발명은 상술한 바와 같이 보호력과 가공성이라는 점착 테이프의 주요 성능을 달성하고자, 상이한 물성을 갖는 두 개의 필름으로 이루어진 다층 구조의 점착 테이프를 제공한다. 특히 상부 필름의 마찰력을 하부 필름보다 낮게 하여, 가공성을 향상시키며, 동시에 하부 필름은 우수한 탄성 특성 및 두꺼운 두께를 가짐으로써 표면 보호력을 향상시켰다.
The present invention provides a pressure-sensitive adhesive tape of a multilayer structure consisting of two films having different physical properties, in order to achieve the main performance of the pressure-sensitive adhesive tape of protection and processability as described above. In particular, the frictional force of the upper film is lower than that of the lower film, thereby improving workability, while at the same time the lower film has excellent elastic properties and thick thickness, thereby improving surface protection.

도 1은 본 발명의 일 실시예에 따른 다층 구조의 점착 테이프의 단면도이다.1 is a cross-sectional view of an adhesive tape of a multilayer structure according to an embodiment of the present invention.

도 1을 참조하면, 상기 점착 테이프는 점착제(110)가 일면에 도포된 제 1 필름(120) 및 상기 제 1 필름(120)의 타면에 접합된 제 2 필름(130)을 포함하는 구조이다. 특히 본 발명은 상기 제 2 필름(130)의 마찰계수(COF, coefficient of friction)가 0.07 내지 0.2인 경우, 본 발명에 따른 보호 테이프의 가공 특성이 현저하게 향상되는 점에 기초하여 본 발명에 이르게 되었다. 이때, 상기 하부의 제 1 필름(120)의 마찰력은 제 2 필름(130)보다 높으며, 따라서 상기 제 1 필름(120)의 마찰계수는 제 2 필름(130)의 마찰계수보다 높을 수 있다.
Referring to FIG. 1, the adhesive tape has a structure including a first film 120 having an adhesive 110 applied to one surface and a second film 130 bonded to the other surface of the first film 120. In particular, the present invention leads to the present invention based on the fact that the processing characteristics of the protective tape according to the present invention are significantly improved when the coefficient of friction (COF) of the second film 130 is 0.07 to 0.2. It became. In this case, the frictional force of the lower first film 120 may be higher than that of the second film 130. Therefore, the frictional coefficient of the first film 120 may be higher than the frictional coefficient of the second film 130.

더 나아가, 본 발명에 따른 보호용 점착 테이프의 제 2 필름(130)은 제 1 필름(120)보다 높은 충격강도(Impact Strength)를 갖는 것이 바람직한데, 그 이유는 제 2 필름(130)이 표면 충격으로부터 최초 충격을 흡수하는 층이기 때문이다. 즉, 상부의 필름층으로 동일한 층을 중첩하여 사용하는 종래 기술과 달리, 본 발명은 상부 필름의 마찰력 및 충격 강도를 달리함으로써 보호 테이프의 보호 효과 이외에 가공성 등을 향상시키며, 이러한 제 2 필름(130)의 물질로서 배향폴리프로필렌(OPP), 고밀도 폴리에틸렌(HDPE), 폴리프로필렌(PP) 및 폴리에틸렌테레플탈레이트(PET)로 이루어진 군으로부터 선택된 하나 이상의 중합체를 제공한다. 또한, 점착제가 일면에 도포되며, 보호 표면에 직접 접촉하는 제 1 필름(130)은 제 2 필름(130)보다는 높은 마찰력을 가져도 무방하므로, 본 발명은 제 1 필름(120)의 성분으로 폴리에틸렌(PE), 폴리염화비닐(PVC), 에틸렌비닐아세테이트(EVA) 및 폴리우레탄(PU)으로 이루어진 군으로부터 선택된 중합체를 제공한다. Furthermore, it is preferable that the second film 130 of the protective adhesive tape according to the present invention has a higher impact strength than the first film 120, because the second film 130 has a surface impact. It is because it is a layer which absorbs an initial shock from the. That is, unlike the prior art of using the same layer by overlapping the upper film layer, the present invention improves processability and the like in addition to the protective effect of the protective tape by varying the frictional force and impact strength of the upper film, the second film 130 ), At least one polymer selected from the group consisting of oriented polypropylene (OPP), high density polyethylene (HDPE), polypropylene (PP) and polyethylene terephthalate (PET). In addition, since the pressure-sensitive adhesive is applied to one surface, the first film 130 in direct contact with the protective surface may have a higher friction than the second film 130, the present invention is a polyethylene as a component of the first film 120 (PE), polyvinyl chloride (PVC), ethylene vinyl acetate (EVA) and polyurethane (PU).

본 발명의 일 실시예에서 Notched Izod(73F) 방식으로 측정된 충격 강도는, 제 2 필름(130)은 2.0 이상, 제 1 필름(120)은 2.0이하였다. In one embodiment of the present invention, the impact strength measured by the Notched Izod (73F) method, the second film 130 is 2.0 or more, the first film 120 was 2.0 or less.

또한 제 1 필름(120)의 굴곡탄성계수(Flexural Modules of Elasticity, 73F)는 250,000~480,000(PSI), 제 2 필름(130)의 굴곡탄성계수는 100,000 내지 250, 0000(PSI)인 것이 바람직하다. 즉, 제 2 필름(130)이 보다 탄성이 큰 경우, 외부에서 가해지는 힘에 대하여 제 2 필름(130)은 보다 용이하게 휘어지거나, 변형되므로, 보호필름 전체의 가공성 향상에 기여하게 된다. In addition, the flexural modulus of elasticity (Flexural Modules of Elasticity, 73F) of the first film 120 is 250,000 ~ 480,000 (PSI), the flexural modulus of the second film 130 is preferably 100,000 to 250, 0000 (PSI). . That is, when the second film 130 is more elastic, the second film 130 is more easily bent or deformed with respect to a force applied from the outside, thereby contributing to the improvement of processability of the entire protective film.

또한, 상기 제 1 필름(120)의 두께는 35 내지 130μm, 상기 제 2 필름(130)의 두께는 15 내지 100μm 인 것이 바람직하다. 즉, 상기 제 1 필름(120)의 두께의 가용 범위가 제 2 필름(130)보다는 더 두꺼운 경향을 보이는데, 그 이유는 제 1 필름(120)이 기본적인 표면 보호 역할을 수행하는 저층이기 때문이다. 만약, 상기 제 1 필름(120)의 두께가 상기 범위보다 얇다면 충분한 표면 보호 효과를 기대하기 어렵고, 반대로 상기 범위보다 두꺼우면 가공성이 떨어지기 때문이다. 또한, 본 발명의 일 실시예에서 상기 점착제(110)는 합성고무, 천연고무, 아크릴계 또는 우레탄 계 점착제이며, 상기 제 2 필름(130) 상부에는 보호테이프가 롤 상태로 감긴 뒤 쉽게 풀릴 수 있도록 하는 이형기능을 가지는 층인 이형제가 적층될 수 있다.
In addition, the thickness of the first film 120 is 35 to 130μm, the thickness of the second film 130 is preferably 15 to 100μm. That is, the available range of the thickness of the first film 120 tends to be thicker than the second film 130, because the first film 120 is a low layer that serves as a basic surface protection role. If the thickness of the first film 120 is thinner than the above range, it is difficult to expect a sufficient surface protection effect. On the contrary, if the thickness of the first film 120 is thicker than the above range, the workability is inferior. In addition, in one embodiment of the present invention, the pressure-sensitive adhesive 110 is a synthetic rubber, natural rubber, acrylic or urethane-based pressure-sensitive adhesive, the second film 130, the protective tape is wound on a roll state so that it can be easily released A release agent, which is a layer having a release function, may be laminated.

이하 절곡실험을 통하여 본 발명에 따른 보호테이프의 효과를 설명한다.

PVC 단일층의 보호테이프를 실시예와 동일한 두께로 제조하였다.
The protective tape of the PVC single layer was prepared in the same thickness as in Example.

실험결과Experiment result

도 2 및 3은 비교예의 보호테이프를 보호표면에 접착시킨 후, 표면을 절곡시킨 후의 사진이다. 2 and 3 are photographs after the protective tape of the comparative example is bonded to the protective surface and then the surface is bent.

도 2 및 3을 참조하면, 표면 절곡에 따라 보호 테이프의 표면이 불규칙적으로 변화됨을 알 수 있다. 이것은 결국 보호 테이프의 표면 접착력이 약화되는 것을 의미한다. 2 and 3, it can be seen that the surface of the protective tape is irregularly changed as the surface is bent. This in turn means that the surface adhesion of the protective tape is weakened.

도 4 및 5는 본 발명에 따른 보호 테이프를 표면에 접착시킨 후, 동일한 방식으로 표면을 절곡시킨 후의 사진이다. 4 and 5 are photographs after the protective tape according to the present invention is adhered to the surface, and then the surface is bent in the same manner.

도 4 및 5를 참조하면, 표면 절곡이 일어났음에도 불구하고, 이층 구조의 보호 테이프는 균일한 표면 특성을 보이며, 절곡 전과 동일하게 표면과의 균일합 접착 상태를 보이는 것을 알 수 있다. 4 and 5, although the surface bending occurs, it can be seen that the protective tape of the two-layer structure shows a uniform surface characteristics, and evenly bonded state with the surface as before the bending.
