Abstract
Description
本発明は、有機過酸化物により硬化する熱硬化性シリコーン組成物に関する。 The present invention relates to a thermosetting silicone composition that is cured by an organic peroxide.
発光ダイオード(LED)は、その発光効率の目覚ましい向上を背景とし、低い消費電力、高寿命、意匠性などを特長として液晶ディスプレイ(LCD)のバックライト向けや、車のヘッドライト等の車載分野ばかりではなく一般照明向けでも急激に市場を拡大しつつある。 Light emitting diodes (LEDs) are characterized by their low power consumption, long life, and designability against the background of remarkable improvement in luminous efficiency. The market is expanding rapidly even for general lighting.
LEDの発光スペクトルは、LEDチップを形成する半導体材料に依存するためその発光色は限られている。そのため、LEDを用いてLCDバックライトや一般照明向けの白色光を得るためにはLEDチップ上にそれぞれのチップに適合した蛍光体を配置し、発光波長を変換する必要がある。具体的には、青色発光するLEDチップ上に黄色蛍光体を設置する方法、青色発光するLEDチップ上に赤および緑の蛍光体を設置する方法、紫外線を発するLEDチップ上に赤、緑、青の蛍光体を設置する方法などが提案されている。これらの中で、LEDチップの発光効率やコストの面から青色LED上に黄色蛍光体を設置する方法、および青色LED上に赤および緑の蛍光体を設置する方法が現在最も広く採用されている。 Since the emission spectrum of an LED depends on the semiconductor material forming the LED chip, its emission color is limited. Therefore, in order to obtain white light for LCD backlights and general lighting using LEDs, it is necessary to arrange a phosphor suitable for each chip on the LED chip and convert the emission wavelength. Specifically, a method of installing a yellow phosphor on an LED chip that emits blue light, a method of installing red and green phosphors on an LED chip that emits blue light, and a method of installing red, green, and blue on an LED chip that emits ultraviolet light. A method of installing the fluorescent substance of the above has been proposed. Among these, the method of installing the yellow phosphor on the blue LED and the method of installing the red and green phosphors on the blue LED are currently the most widely adopted in terms of the luminous efficiency and cost of the LED chip. ..
LEDチップ上に蛍光体を設置する具体的な方法の1つとして、LEDチップ上に、ハイドロジェンオルガノポリシロキサンとアルケニル基含有オルガノポリシロキサンを反応させる付加硬化型シリコーン組成物中に蛍光体を分散させたシートを貼りつける方法が提案されている。しかし、この方法では蛍光体シートを作製する際に付加反応が進んでしまわないようにシートを低温で保管しなければならず、また、組成中に付加反応制御剤を多量に添加する必要があった(特許文献1〜5)。 As one of the specific methods for placing the fluorescent substance on the LED chip, the fluorescent substance is dispersed in an addition-curable silicone composition in which a hydrogen organopolysiloxane and an alkenyl group-containing organopolysiloxane are reacted on the LED chip. A method of pasting the sheet is proposed. However, in this method, the sheet must be stored at a low temperature so that the addition reaction does not proceed when the phosphor sheet is prepared, and it is necessary to add a large amount of the addition reaction control agent to the composition. (Patent Documents 1 to 5).
本発明は上記事情に鑑みなされたもので、反応制御剤を添加せずとも未硬化状態における安定性に優れ、高硬度の硬化物を与える熱硬化性シリコーン組成物を提供することを目的とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a thermosetting silicone composition which is excellent in stability in an uncured state without adding a reaction control agent and gives a cured product having a high hardness. ..

上記実施例1〜4および比較例1〜3で得られた組成物について、厚み2mmのテフロン(登録商標)製の枠に流し込み、60℃1時間、80℃1時間、100℃1時間の順に加熱することにより溶剤を揮発させ、シートを作製した。得られたシートについて以下の試験(1)、(2)を行い、物性を確認した。その結果を表1に示す。 The compositions obtained in Examples 1 to 4 and Comparative Examples 1 to 3 were poured into a Teflon (registered trademark) frame having a thickness of 2 mm, and were poured in the order of 60 ° C. for 1 hour, 80 ° C. for 1 hour, and 100 ° C. for 1 hour. The solvent was volatilized by heating to prepare a sheet. The following tests (1) and (2) were performed on the obtained sheet to confirm the physical properties. The results are shown in Table 1.
試験(1):シートを120℃に10分間晒した後、トルエンに可溶か否かを確認した。
試験(2):シートを150℃で3時間硬化し、得られた硬化物の外観を観察し、硬さを測定した。
・外観:目視にて亀裂の有無を観察した。
亀裂無し(○),亀裂有り(×)
・硬さ:上島製作所(株)製デュロメータタイプD型硬度計にて測定した。
Test (1): After exposing the sheet to 120 ° C. for 10 minutes, it was confirmed whether or not the sheet was soluble in toluene.
Test (2): The sheet was cured at 150 ° C. for 3 hours, the appearance of the obtained cured product was observed, and the hardness was measured.
-Appearance: The presence or absence of cracks was visually observed.
No crack (○), with crack (×)
-Hardness: Measured with a durometer type D type hardness tester manufactured by Ueshima Seisakusho Co., Ltd.
表1に示されるように、実施例1〜4で得られたシートは、120℃10分間の加熱後においてもトルエンに可溶であり、未硬化状態を保っていた。また、150℃で3時間加熱することにより高硬度の硬化物を与えることが示された。 As shown in Table 1, the sheets obtained in Examples 1 to 4 were soluble in toluene even after heating at 120 ° C. for 10 minutes and remained in an uncured state. It was also shown that heating at 150 ° C. for 3 hours gives a hardened product of high hardness.
一方、ヒドロシリル化による硬化性組成物である比較例1では、反応制御剤が存在していても120℃10分間の加熱により硬化し、未硬化状態を保つことができなかった。また、(A)成分を含有しない比較例2では硬化物の硬度が著しく低下し、(B)成分を含有しない比較例3では硬化物に亀裂が発生した。 On the other hand, in Comparative Example 1, which is a curable composition by hydrosilylation, even in the presence of the reaction control agent, it was cured by heating at 120 ° C. for 10 minutes, and the uncured state could not be maintained. Further, in Comparative Example 2 containing no component (A), the hardness of the cured product was significantly reduced, and in Comparative Example 3 containing no component (B), cracks were generated in the cured product.
