Description

감압성 점착제{Pressure sensitive adhesive}Pressure sensitive adhesive

본 발명은 액정디스플레이의 편광판용 또는 자동차용 햇빛 차단용 필름에 사용되는 감압성 점착제에 관한 것이다.The present invention relates to a pressure-sensitive adhesive for use in a polarizing plate or a sunscreen film for automobiles of liquid crystal display.

정보화사회에 살고 있는 요즘, 그 정보의 중요성은 나날이 증가하고 있는 실정이며, 특히 디스플레이에 대한 요구는 칼라화와 더불어 소형화, 경량화, 박형화가 강하게 대두되고 있으며, 그 중에서도 액정 칼라 디스플레이는 그 요구에 충분히 부응할 수 있는 것으로 주목받아 실용화가 급격히 진행되고 있다. 그리고 추후에도 액정텔레비젼, 비디오모니터, 카메라, 스캐너, 노트북컴퓨터, 게임기 등 그 사용형태가 다양화되고, 그 성능에 대해서도 우수한 품질이 더욱 요구될 것은 자명하다. 특히 액정칼라디스플레이에서 편광판은 핵심부품의 하나이고, 이와 더불어 사용환경조건의 확대에 따른 신뢰성 확보, 프로세스 간단화에 따른 제조비용의 절감 등의 필요성이 증대되고 있다.In today's information society, the importance of information is increasing day by day, and the demand for displays is particularly high in size, weight, thickness, and liquid crystal color display. It is attracting attention as being able to respond, and commercialization is progressing rapidly. In the future, it is obvious that LCD TVs, video monitors, cameras, scanners, notebook computers, game consoles, and the like will be diversified, and excellent quality will be required for their performance. In particular, the polarizing plate is one of the core components in the liquid crystal color display, and the necessity of securing reliability by expanding the use environment conditions and reducing the manufacturing cost by simplifying the process is increasing.

최근 이러한 편광판이나 햇빛 차단 필름에 사용되는 감압성 점착제는 작업성이 좋기 때문에 많은 분야에서 이용되고 있으며, 특히 그 중에서도 아크릴계 감압성 점착제는 내후성, 내열성, 내화학성 등이 우수하여 그러한 성능이 요구되는 분야에서 많이 사용되어지고 있다.Recently, pressure-sensitive adhesives used in such polarizing plates and sunscreen films have been used in many fields because of their good workability, and in particular, acrylic pressure-sensitive adhesives have excellent weather resistance, heat resistance, chemical resistance, and the like, and require such performance. It is used a lot in.

이러한 감압성 점착제는 피착물에의 도막성이 우수하고, 또한 양호한 초기 점착력을 발휘할 뿐더러 동시에 점착후의 피착물에 잔류하는 응력에 대항하는 큰 응집력을 가져 초기접착력을 실질적으로 유지할 수 있어야 한다. 또한 우수한 내잔류응력성을 가지고 고온고습하에서 장시간 방치시키는 등의 가혹조건에 방치하여도 피착물에 새로이 발생하는 응력에 대해 충분히 대항하는 우수한 내구성을 가져야 바람직하다. 이러한 관점에서 아크릴계 감압성 점착제에 있어서는 현재까지 점착주성분으로서 사용되는 아크릴계 수지의 모노마조성을 변경하거나 혹은 그 수지와 함께 적당한 점착부여수지 및 가소제 등을 배합하여 사용하거나, 또는 각종 가교제를 첨가하여 상기 수지를 가교하는 등의 성능개선 연구들이 진행되고 있다.Such a pressure-sensitive adhesive should be excellent in coating property to the adherend, exhibit good initial adhesive force, and at the same time have a large cohesive force against stress remaining on the adherend after adhesion, and should be able to substantially maintain the initial adhesive force. In addition, it is preferable to have excellent durability against the stresses newly generated in the adherend even if it is left under severe conditions such as long standing under high temperature and high humidity with excellent residual stress resistance. From this point of view, in the acrylic pressure-sensitive adhesive, the resin may be used by changing the monoma formability of the acrylic resin used as an adhesive main component until now, or by using a suitable tackifying resin and a plasticizer in combination with the resin, or by adding various crosslinking agents. Performance improvement studies such as crosslinking are being conducted.

그러나, 상기와 같은 기존의 점착제는 초기접착력과 내잔류응력성 모두 우수하고 게다가 내구성을 고도로 만족하는 정도의 성능을 발현시키지는 못하였으며, 또한 기존에 사용하던 점착제는 내습성이나 또는 일정한 온도 및 습도에서 숙성을 해야만 하는 단점도 있다. 본 발명은 이와 같은 문제를 해결할뿐더러 초기접착력과 내잔류응력성에서 모두 우수하고, 우수한 내구성을 지닌 아크릴계 감압성 점착제를 제공하는 것을 목적으로 한 것이다.However, the existing pressure sensitive adhesive as described above is excellent in both the initial adhesive strength and the residual stress resistance, and also does not express the degree of performance that satisfactorily satisfies the durability. In addition, the conventional pressure sensitive adhesive has a moisture resistance or at a constant temperature and humidity. There are also disadvantages that must be matured. The present invention not only solves such a problem, but also provides an acrylic pressure-sensitive adhesive having excellent initial adhesive strength and residual stress resistance and excellent durability.
