Description
본 발명은 박막 폴리우레탄 폼(Polyurethane foam) 테이프 및 그 제조방법에 관한 것으로서, 더욱 상세하게는 점착테이프 공정 개선을 통해 초박형 폼 상태로도 테이프를 제조할 수 있도록 한 박막 폴리우레탄 폼 테이프 및 그 제조방법에 관한 것이다.
The present invention relates to a thin film of polyurethane foam (Polyurethane foam) tape and a method for manufacturing the same, and more particularly to a thin film polyurethane foam tape and to produce a tape in an ultra-thin foam state by improving the adhesive tape process It is about a method.
1990년대 이후 전기, 전자 산업이 발전하면서 다양한 테이프가 전기, 전자산업에 적용되기 시작하였다. 아울러 자동차 분야는 부품소재의 개발과 함께 경량화, 기능화를 필요로 하여 점착테이프의 사용이 증가하고 있는 실정이다. 이들 적용 분야 외 휴대폰 기기에 사용되는 작은 부품을 비롯하여 대면적의 디스플레이 패널에 이르기까지 많은 부품을 조합하는 데 점착테이프는 최적의 해결책이었으며, 부품 사이의 공간을 최소화하고 외관도 깨끗하게 만드는 데 많은 기여를 했다.Since the 1990s, with the development of the electrical and electronics industry, various tapes have been applied to the electrical and electronics industry. In addition, in the automotive field, the use of adhesive tapes is increasing due to the development of parts and materials, which requires light weight and functionalization. In addition to these applications, adhesive tapes have been the optimal solution for combining many components, from small parts used in mobile devices to large display panels, and have contributed significantly to minimizing the space between parts and making their appearance clean. did.
최근 들어 전기, 전자부품의 기능화에 따라 테이프도 구조적으로 변화하였으며 디스플레이 패널의 제조공정을 예로 들면, 접합면의 경량화 및 대면적화에 따른 테이프 물성의 신뢰성, 패널 조립 후 성능 검사 시 발생한 문제를 해결하기 위한 탈착 작업의 용이성 등을 필요로 하여 다양한 구조물 및 기능을 필요로 한 점착테이프가 사용되고 있다.In recent years, the tape has also been structurally changed according to the functionalization of electrical and electronic components. For example, the manufacturing process of the display panel is used to solve the problems caused by the reliability of the tape properties due to lightening and large area of the bonding surface and performance inspection after panel assembly. Adhesive tapes requiring various structures and functions have been used for the ease of desorption work.
디스플레이 패널은 여러 공정을 거처 조립되고 패널의 경량화 및 슬림화를 위해 점착테이프가 사용되며, 일반적으로 금속패널과 유리패널 사이에 적용된다. 디스플레이 패널은 조립완료 후 성능검사를 수행하며 조립의 불량 및 결함 발생시 각 조립부품 중 금속패널과 유리 패널을 분리시켜야 한다. 기존의 분리공정은 패널에 고온의 열을 가하여 점착테이프의 열탈착 특성을 이용하여 왔다. 이 방법은 열탈착에 소요되는 시간이 오래 걸리며 고온의 열로 인해 디스플레이 패널에 손상을 줄 수 있고 에너지 손실을 유발한다.The display panel is assembled through various processes and adhesive tape is used to make the panel lighter and slimmer, and is generally applied between the metal panel and the glass panel. The display panel performs the performance test after the assembly is completed. In case of defects and defects in assembly, the metal panel and the glass panel should be separated. Conventional separation process has been utilizing the thermal desorption characteristics of the adhesive tape by applying a high temperature heat to the panel. This method takes a long time for thermal desorption, and high temperature heat may damage the display panel and cause energy loss.
상기의 열탈착 문제를 해결하기 위해서는 상온에서 패널 간의 분리가 용이한 구조물을 필요로 한다. 상온에서 금속패널과 유리패널의 분리는 패널 사이에 있는 점착테이프를 두께가 가는 칼로 절개시키는 방법이다, 절개시킨 각각의 패널은 표면에 붙어있는 점착테이프를 제거하면 곧바로 재사용이 가능하게 된다. 이때 두께가 가는 칼로 절개 가능한 점착테이프는 구조적으로 공극구조이어야 하고, 이러한 공극구조로는 고분자 발포 폼 양면테이프, 부직포 합침 양면 테이프 등이 있다.In order to solve the thermal desorption problem, a structure that can be easily separated between panels at room temperature is required. Separation of the metal panel and the glass panel at room temperature is a method of cutting the adhesive tape between the panels with a thin knife. Each of the cut panels can be reused as soon as the adhesive tape on the surface is removed. At this time, the adhesive tape that can be cut with a thin knife should be structurally pore structure, and such pore structures include polymer foam foam double-sided tape and nonwoven fabric double-sided tape.

The prepared adhesive tape structure can be applied to the liquid crystal alignment film display panel, the plasma display panel and the shock absorber for assembling electrical and electronic components, the shock absorbing buffer for automobiles.
이러한 종래 기술은 상온에서 탈착 작업 시 발포 폼을 절개하여 쉽게 테이프를 제거할 수 있도록 작업성을 개선하였고, 테이프 제거 시 점착제를 완벽하게 제거함으로써 디스플레이 패널의 금속과 유리의 재사용이 가능하다는 장점이 있다.
This prior art has improved workability to easily remove the tape by cutting the foam foam at the room temperature desorption operation, there is an advantage that the metal and glass of the display panel can be reused by completely removing the adhesive when removing the tape. .

However, the prior art as described above has the advantage that it is easy to remove the tape through the foam foam incision, but due to the characteristics of the polyurethane foam is too soft problem it is impossible to manufacture the tape by processing a single polyurethane foam of 500㎛ or less There was a problem.
이러한 종래기술의 문제점을 해결하기 위해서 근래에는 PET 필름을 기재로 한 포론 등의 형태로 점착테이프를 제조하였으나, 이러한 경우 공정이 복잡하다는 단점이 있다.In order to solve the problems of the prior art, the adhesive tape is manufactured in the form of poron based on PET film, but in this case, there is a disadvantage in that the process is complicated.
이에 본 발명은 상기와 같은 종래기술의 제반 문제점을 해소하기 위해서 제안된 것으로서,Accordingly, the present invention has been proposed to solve all the problems of the prior art as described above,
