Description

本発明は、低温硬化型液状エポキシ樹脂組成物に関する。   The present invention relates to a low-temperature curable liquid epoxy resin composition.

センサー素子等の部材は高性能化や小型化が進み、より低温環境下での製造が要求されている。それに伴って、これらの部材に使用される熱硬化性エポキシ樹脂組成物の特性として、保存安定性に優れ、低温で迅速に硬化し、低弾性及び低光沢性を有する硬化物を得られることが求められている。   Members such as sensor elements have been improved in performance and size, and are required to be manufactured in a lower temperature environment. As a result, the thermosetting epoxy resin composition used in these members has excellent storage stability, can be cured quickly at low temperatures, and a cured product having low elasticity and low gloss can be obtained. It has been demanded.

現在、低温硬化型樹脂として頻用される二液硬化型エポキシ樹脂は、使用時の混合作業が必要となり、取り扱いが悪いという問題点がある。また、低温硬化性及び保存安定性は相反する性質であり、一液硬化型エポキシ樹脂において両者を両立させることは難しい。そのため、潜在型硬化剤や潜在型硬化促進剤を用いた一液低温硬化型エポキシ樹脂が開発されている。   Currently, the two-component curable epoxy resin frequently used as a low-temperature curable resin requires a mixing operation at the time of use, and has a problem that handling is poor. Moreover, low temperature curability and storage stability are contradictory properties, and it is difficult to make both compatible in a one-component curable epoxy resin. Therefore, a one-component low-temperature curable epoxy resin using a latent curing agent or a latent curing accelerator has been developed.

特許文献1では、アミン化合物とポリグリシジル化合物とを反応させて得られる付加反応物、及び、フェノール樹脂を含有する潜在性硬化剤を用いた一液低温硬化型エポキシ樹脂組成物が開示されている。しかし、該一液低温硬化型エポキシ樹脂組成物ではビスフェノール系エポキシ樹脂が用いられており、弾性率が高く、熱サイクル信頼性が低い。   Patent Document 1 discloses an addition reaction product obtained by reacting an amine compound and a polyglycidyl compound, and a one-component low-temperature curable epoxy resin composition using a latent curing agent containing a phenol resin. . However, the one-component low-temperature curable epoxy resin composition uses a bisphenol-based epoxy resin, and has a high elastic modulus and low thermal cycle reliability.

また、特許文献2では、1分子内にチオール基を2個以上有するポリチオール化合物を硬化剤として用いた一液硬化型エポキシ樹脂組成物が開示されている。しかし、チオール系化合物は臭気が強く、また、他の熱硬化性樹脂の硬化を阻害する場合もあり、その使用が避けられている。   Patent Document 2 discloses a one-component curable epoxy resin composition using a polythiol compound having two or more thiol groups in one molecule as a curing agent. However, the thiol compound has a strong odor and may inhibit the curing of other thermosetting resins, and its use is avoided.

上述したように、これまで保存安定性に優れ、低温で迅速に硬化し、低弾性及び低光沢性を有する硬化物となるエポキシ樹脂組成物の開発は十分でなかった。   As described above, development of an epoxy resin composition that has been excellent in storage stability, cured rapidly at a low temperature, and becomes a cured product having low elasticity and low gloss has been insufficient.

表1に示されるように、フェノール系硬化剤を用いた比較例1及び2では、反応率が低く、保存安定性も悪かった。また、比較例3及び4では、曲げ弾性率が高く、光沢度が大きく、反応率が劣っていた。一方、両末端グリシジル基変性エポキシ樹脂とポリアミン系硬化剤とを併用した実施例1〜3では、保存安定性が良く、反応率が高かった。また、実施例1〜3では、曲げ弾性率が低く、接着力が高かった。さらに、カーボンブラックや(メタ)アクリル樹脂を添加した実施例4では、光沢度及び光透過率が低いため、この組成物はセンサー向けの封止材や接着剤として有用であることが分かった。   As shown in Table 1, in Comparative Examples 1 and 2 using a phenolic curing agent, the reaction rate was low and the storage stability was also poor.
