LED(Light Emitting Diode)는 표시 장치의 광원이나 조명 등 다양한 분야에서 활용되고 있는 소자이다. Light emitting diodes (LEDs) are devices that are utilized in various fields such as light sources and lighting of display devices.
LED 봉지재로서, 접착성이 높고 역학적인 내구성이 우수한 에폭시 수지가 폭넓게 이용되고 있다. 그러나, 에폭시 수지는 청색 내지 자외선 영역의 광에 대한 투과율이 낮고, 또한 내열성과 내광성이 떨어지는 문제점이 있다. 이에 따라, 예를 들면, 특허문헌 1 내지 3 등에서는, 상기와 같은 문제점의 개량하기 위한 기술을 제안하고 있다. 그러나, 현재까지 알려진 봉지재는, 가스 배리어성이나 접착성 등이 충분하지 못하고, 내열성, 내열충격성과 균열 내성이 부족하다.As the LED encapsulant, an epoxy resin having high adhesiveness and excellent mechanical durability is widely used. However, the epoxy resin has a problem in that the transmittance of light in the blue to ultraviolet region is low, and the heat resistance and light resistance are inferior. Accordingly, for example, Patent Documents 1 to 3 propose techniques for improving the above problems. However, the sealing material known to date is insufficient in gas barrier property, adhesiveness, etc., and lacks heat resistance, heat shock resistance, and crack resistance.

However, the present inventors are difficult to control the ratio only by controlling only the ratio between the aliphatic unsaturated bonds contained in the polyorganosiloxane and the hydrogen atoms present in the crosslinking agent and the catalyst promoting the reaction therebetween. It was confirmed that the environment of the reaction should also be considered. For example, optical semiconductors such as LEDs, which are the main uses of the cured bodies, include various housing materials such as polyphthalamide (PPA), polycyclohexylene-dimethylene terephthalates (PCT), epoxy molding compound (EMC), and white silicone, Depending on the application, any one of the above housing materials is selected and used. The hardening process in which the hardened body is formed is usually performed in a state in which a curable composition, that is, a mixture containing the polyorganosiloxane and a crosslinking agent is injected into the housing material, and according to the housing material, a lot of outgassing occurs during the hardening process. And out-gassing inhibits hardening to inhibit the reaction of the aliphatic unsaturated bonds and hydrogen atoms, thereby making it difficult to achieve the desired ratio (C / Si).
따라서, 상기 비율(C/Si)의 달성을 위하여는 아웃 개싱이 적은 하우징을 선택하거나, 혹은 아웃 개싱이 발생하는 하우징에 대하여 선베이킹(prebaking) 공정을 진행한 후 경화성 조성물의 주입과 경화 공정을 진행하는 것이 유리할 수 있다.Therefore, in order to achieve the ratio (C / Si), a housing having a low outgassing is selected, or a prebaking process is performed on a housing in which outgassing occurs, and then injection and curing of the curable composition are performed. It may be advantageous to proceed.
상기 사항 외에도 경화성 조성물의 경화와 관련된 인자는 다양하고, 그러한 인자를 고려하여 상기 비율(C/Si 등)의 달성이 가능하도록 경화 반응이 진행될 필요가 있다.In addition to the above, there are various factors related to the curing of the curable composition, and in consideration of such factors, the curing reaction needs to proceed so that the ratio (C / Si, etc.) can be achieved.
