Definitions
- the present invention relates to a curable resin composition.
- a curable resin composition containing a silicone resin has been known, and is used, for example, as an optical semiconductor sealing composition for sealing an optical semiconductor such as a light-emitting diode (LED).
- LED light-emitting diode
- (A) a branched chain having at least 3 alkenyl groups in one molecule and at least 30 mol% of all silicon-bonded organic groups is an aryl group”.
- Organopolysiloxane (B) linear organopolysiloxane having both ends of the molecular chain blocked with diorganohydrogensiloxy groups and having an aryl group, (C) at least 3 diorganohydrogens in one molecule
- a curable organopolysiloxane composition comprising a branched organopolysiloxane having a siloxy group and at least 15 mol% of all silicon-bonded organic groups being an aryl group, and (D) a catalyst for hydrosilylation reaction. Is described.
- Patent Document 1 substantially discloses only the component (B) having a polymerization degree of 1 or about 6 to 7.
- the inventors of the present invention have revealed that such a “curable organopolysiloxane composition” disclosed in Patent Document 1 has insufficient adhesion of the cured product.
- a linear organopolysiloxane having an alkenyl group and a linear organopolysiloxane having two or more silicon-bonded hydrogen atoms are used in combination. It was found that the adhesion was improved by using a curable resin composition having a degree of polymerization of the organopolysiloxane in the form of “over 10”.
- an LED chip a very small dice-shaped chip in which two kinds of semiconductors are bonded together
- an LED package in which an LED chip is sealed and easily connected to a substrate is called an LED package.
- COB chip-on-board
- the present inventors have used the curable resin composition containing the linear organopolysiloxane having a polymerization degree of “greater than 10” as a sealing material for sealing such COB LEDs. Used and studied. Specifically, a phosphor was added to the composition and cured, and the cured product was evaluated. As a result, spots (mottle) may occur in the cured product. If spots occur, the appearance and brightness may be significantly impaired.
- the present inventors considered that the occurrence of plaques originated from the precipitation of the phosphor, and added silica such as fumed silica to the curable resin composition from the viewpoint of preventing the precipitation of the phosphor. As a result, it was found that although the effect of suppressing the occurrence of spots was observed, the transparency required as a sealing material for optical semiconductors may be impaired.
- the present invention has been made in view of the above points, and an object of the present invention is to provide a curable resin composition from which a cured product having good transparency and capable of suppressing the occurrence of spots can be obtained.
- the present inventors have further added organopolysiloxane having a silanol group to the curable resin composition, while maintaining good transparency.

式(C1)中、各R31は独立に、置換または非置換の一価炭化水素基である。この一価炭化水素基としては、例えば、メチル基、エチル基、n-プロピル基、イソプロピル基、n-ブチル基、イソブチル基、sec-ブチル基、tert-ブチル基、各種ペンチル基、各種ヘキシル基、各種オクチル基、各種デシル基、シクロペンチル基、シクロヘキシル基などの炭素数1~18のアルキル基;ビニル基、アリル基、ブテニル基、ペンテニル基、ヘキセニル基、オクテニル基などの炭素数2~18のアルケニル基;フェニル基、トリル基、キシリル基などの炭素数6~18のアリール基;ベンジル基、フェネチル基などの炭素数7~18のアラルキル基;3-クロロプロピル基、3,3,3-トリフロロプロピル基などの炭素数1~18のハロゲン化アルキル基;等が挙げられる。
ただし、1分子中、R31の少なくとも1個はアルケニル基であり、アルケニル基であるR31が2~12質量%となる量が好ましく、3~10質量%がより好ましい。
また、1分子中、R31の少なくとも1個はアリール基であり、全R31の少なくとも30モル%はアリール基であるのが好ましく、少なくとも40モル%はアリール基であるのがより好ましい。
式(C1)中、X31は水素原子またはアルキル基である。このアルキル基としては、上述したX12のアルキル基と同義である。

なお、分岐鎖状オルガノポリシロキサン(C)は、非常に粘稠な半固体状物または個体状物であり、粘度の測定は困難である。
Si-H/Si-Viモル比がこの範囲であれば、本発明の組成物の硬化性が優れ、また、硬化物の密着性も優れる。
本発明の組成物に含有されるヒドロシリル化反応用触媒(D)は、ケイ素原子結合水素原子(Si-H)を有するケイ素含有化合物(B)と併用されて、分岐鎖状オルガノポリシロキサン(C)のアルケニル基に対する付加反応(ヒドロシリル化反応)を促進する触媒として機能する。
ヒドロシリル化反応用触媒(D)としては、従来公知のものを使用でき、例えば、白金系触媒、ロジウム系触媒、パラジウム系触媒等が挙げられ、白金系触媒が好ましい。白金系触媒の具体例としては、塩化白金酸、塩化白金酸-オレフィン錯体、塩化白金酸-ジビニルテトラメチルジシロキサン錯体、塩化白金酸-アルコール配位化合物、白金のジケトン錯体、白金ジビニルテトラメチルジシロキサン錯体などが挙げられ、これらを1種単独で用いてもよく、2種以上を併用してもよい。
ヒドロシリル化反応用触媒(D)の含有量は、触媒量であるが、本発明の組成物の硬化性が優れるという理由から、上述したケイ素含有化合物(B)および分岐鎖状オルガノポリシロキサン(C)の合計100質量部に対して、0.00001~0.1質量部が好ましく、0.0001~0.01質量部がより好ましい。
本発明の組成物は、25℃における粘度が50,000mPa・s以下である低粘度オルガノポリシロキサン(E)を含有するのが好ましい。低粘度オルガノポリシロキサン(E)を含有することにより、硬化物の密着性が優れる。これは、低粘度化することによって可とう性が付与され、クラック等が生じにくくなるためと考えられる。
硬化物の密着性がより優れるという理由から、低粘度オルガノポリシロキサン(E)の25℃における粘度は、1,000~30,000mPa・sが好ましい。
(R41SiO3/2)f(R41 2SiO2/2)g(R41 3SiO1/2)h(SiO4/2)i(X41O1/2)j …(E1)

硬化遅延剤(F)の含有量は、本発明の組成物の使用方法等に応じて適宜選択されるが、例えば、上述したケイ素含有化合物(B)および分岐鎖状オルガノポリシロキサン(C)の合計100質量部に対して、0.00001~0.1質量部が好ましく、0.0001~0.01質量部がより好ましい。

エポキシシランとしては、エポキシ基とアルコキシシリル基とを有する化合物であれば特に限定されず、例えば、γ-グリシドキシプロピルメチルジメトキシシラン、γ-グリシドキシプロピルエチルジエトキシシラン、γ-グリシドキシプロピルメチルジエトキシシラン、β-(3,4エポキシシクロヘキシル)エチルメチルジメトキシシランなどのジアルコキシエポキシシラン;γ-グリシドキシプロピルトリメトキシシラン、β-(3,4エポキシシクロヘキシル)エチルトリメトキシシランなどのトリアルコキシエポキシシラン;等が挙げられる。
また、密着付与剤(G)は、例えば、上記エポキシシランの脱水縮合物であってもよく、例えば、γ-グリシドキシプロピルトリメトキシシランとフェニルトリメトキシシランと1,3-ジビニル-1,1,3,3-テトラメチルジシロキサンとを脱水縮合させたエポキシシラン脱水縮合物が挙げられる。
