Description

本発明は、末端ビニルシロキシ基を有し、耐熱性、機械的強度、電気絶縁性などの電気特性、耐水蒸気透過性などの気体透過性、透明性などの光学特性、耐薬品性、耐水性に優れた硬化物を与えるイソシアヌル環含有オルガノポリシロキサンに関する。   The present invention has a terminal vinylsiloxy group, electrical properties such as heat resistance, mechanical strength, electrical insulation, gas permeability such as water vapor permeability, optical properties such as transparency, chemical resistance, water resistance, etc. It is related with the isocyanuric ring containing organopolysiloxane which gives the cured | curing material excellent in this.

従来、付加硬化反応を応用した硬化性シリコーンゴム組成物が広く用いられている。このような硬化性シリコーンゴム組成物は、耐候性、耐熱性、電気絶縁性に優れており、電気電子部品のガスケット材、ポッティング材、コーティング材、ロール材、型取り材等の成形材料、電線被覆用材料、及び自動車用部品材料として広く使用されている。また、その光学特性を生かして光半導体の封止材や接着剤として活用されている。   Conventionally, curable silicone rubber compositions using addition curing reactions have been widely used. Such a curable silicone rubber composition is excellent in weather resistance, heat resistance, and electrical insulation, and is a molding material such as a gasket material, potting material, coating material, roll material, molding material for electric and electronic parts, electric wire, etc. Widely used as coating materials and automotive parts materials. In addition, it is utilized as an optical semiconductor sealing material or adhesive by making use of its optical characteristics.

しかし、このような硬化性シリコーンゴム組成物は、シリコーン特有のシロキサン結合を有するため、そのイオン結合性によって、高温加湿下での使用等の極めて厳しい使用環境下においては、耐薬品性、耐水性、気体透過性といったシリコーンの優れた特性を発揮することが出来ないことがある。また、硬化物の表面にタックがあり、粉塵などが付着しやすいといった欠点もある。特に、シロキサン結合を含有するポリマーは気体透過性に優れており、酸素富化膜として活用されているが、半導体の封止材料としては、その水蒸気透過性が問題となっている。 However, since such a curable silicone rubber composition has a siloxane bond peculiar to silicone, its ionic bond property causes chemical resistance and water resistance under extremely severe use environment such as use under high temperature humidification. In some cases, the excellent properties of silicone such as gas permeability cannot be exhibited. In addition, there is a drawback in that the surface of the cured product is tacky and dust and the like are easily attached. In particular, a polymer containing a siloxane bond is excellent in gas permeability and is used as an oxygen-enriched film, but its water vapor permeability is a problem as a semiconductor sealing material.

イソシアヌル環を含有する重合体、ポリマー、封止剤としては様々なものが知られている。Si−H含有ポリシロキサンにジアリルモノグリシジルイソシアヌレートを付加反応させたイソシアヌル基含有ポリシロキサンをエポキシ基の開環反応で硬化させたもの(特許文献1)、イソシアヌル環含有ポリシロキサンとSi−H含有ポリシロキサンとを付加反応させて硬化したもの(特許文献2)、トリアリルイソシアヌレートとSi−H含有ポリシロキサンとを付加反応させて硬化したもの(特許文献3)、イソシアヌル環およびSi−Hを含有するポリシロキサンと、アルケニル基含有化合物とを付加反応させて硬化したもの(特許文献4〜6)が知られている。 Various polymers, polymers, and sealants containing an isocyanuric ring are known. An isocyanuric group-containing polysiloxane obtained by addition reaction of diallyl monoglycidyl isocyanurate to an Si-H-containing polysiloxane is cured by an epoxy group ring-opening reaction (Patent Document 1), an isocyanuric ring-containing polysiloxane and an Si-H containing Cured by addition reaction of polysiloxane (patent document 2), cured by addition reaction of triallyl isocyanurate and Si-H containing polysiloxane (patent document 3), isocyanuric ring and Si-H. Known are those obtained by addition reaction of a polysiloxane containing and an alkenyl group-containing compound (Patent Documents 4 to 6).

しかし、特許文献1及び2のイソシアヌル環含有重合体は、主剤にシロキサン結合を含むため、柔軟性はあるが架橋剤との相溶性が悪い。また、特許文献1及び2のイソシアヌル環含有重合体は、アルケニル基の存在位置が不確定であるため、付加反応による硬化が困難であり、ハイドロシリレーション(付加反応)の特徴(速やかな硬化反応)が生かされない。特許文献3〜6のイソシアヌル環含有重合体は、架橋密度が高く、剛直で柔軟性に欠ける。 However, since the isocyanuric ring-containing polymers of Patent Documents 1 and 2 contain a siloxane bond in the main component, they are flexible but poorly compatible with the crosslinking agent. In addition, the isocyanuric ring-containing polymers of Patent Documents 1 and 2 are difficult to cure by addition reaction because the position of the alkenyl group is uncertain, and feature of hydrosilylation (addition reaction) (rapid curing reaction) ) Is not alive. The isocyanuric ring-containing polymers of Patent Documents 3 to 6 have a high crosslinking density, are rigid and lack flexibility.

イソシアヌル環含有ポリシロキサンとSi−H含有ポリシロキサンとの付加反応による硬化物であって、柔軟性、硬化特性、相溶性に優れ、光学特性、耐水蒸気透過性に優れる硬化物はない。 It is a cured product by addition reaction of an isocyanuric ring-containing polysiloxane and a Si—H-containing polysiloxane, and there is no cured product having excellent flexibility, curing characteristics, and compatibility, and excellent optical characteristics and water vapor permeability resistance.
