For this reason, if left at room temperature, curing progresses gradually and fluidity deteriorates, which is a disadvantage.

である。The epoxy resin composition referred to in the present invention essentially contains an epoxy resin, a curing agent, the microencapsulated curing accelerator of the present invention, and an inorganic filler, and further includes a flame retardant, a processing agent, a pigment, and a release agent as necessary. It contains a molding agent and other additives.
エポキシ樹脂とはエポキシ基を有するもの全般のことを

本発明の硬化促進剤とは次のようなものをいいマイクロ
カプセル化されていることが必須である。The curing accelerator of the present invention refers to the following, and it is essential that it is microencapsulated.
硬化促進剤とマイクロカプセル壁材の種類及びマイクロ
カプセルの粒径、厚みが技術的にポイントになる。Technical points are the type of curing accelerator and microcapsule wall material, and the particle size and thickness of the microcapsules.
硬化促進剤としては、ジアザビシクロウンデセン、トリ
フェニルホスフィン、２メチルイミダゾール、ジメチル
ベンジルアミン等が挙げられる。Examples of the curing accelerator include diazabicycloundecene, triphenylphosphine, 2methylimidazole, and dimethylbenzylamine.

ン樹脂、フェノール樹脂といった熱硬化性樹脂を用いる
ことができる。What about microcapsule wall materials? Yoshikawa temperature is 100~
150°C is preferred. The elution temperature here refers to the temperature at which the microencapsulated curing accelerator elutes to the outside through the wall material or elutes to the outside when the wall material is destroyed. That is, it is preferable that the curing accelerator is not eluted during mixing and kneading of the composition, but is eluted during molding to bring out the catalytic action of the curing accelerator. For example, thermosetting resins such as melamine resin and phenol resin can be used.
さらに壁材の厚みとしては０１〜１μｍが好ましい。０

大きくなれば、必然的にカプセル強度が弱くなってしま
が好ましい。０．１重量％以下あるいは０．５重量％以
上に添加すると所望の硬化性が得られないからである。Furthermore, the thickness of the wall material is preferably 01 to 1 μm. 0
If it is thinner than 1 μm, the curing accelerator will be eluted during mixing and kneading. Moreover, if the thickness is more than 1 μm, the curing accelerator will not be eluted during molding. Further, the particle size of the microcapsules is preferably 20 μm or less. If it is larger than 20 μm, dispersibility will be poor and curing will be uneven. Furthermore, it is preferable that if the particle size becomes larger, the capsule strength will inevitably become weaker. This is because if it is added in an amount less than 0.1% by weight or more than 0.5% by weight, the desired curability cannot be obtained.
マイクロカプセル化法としては界面沈澱法、界面重合法
や液中硬化被膜法等を挙げることができる。Examples of the microencapsulation method include an interfacial precipitation method, an interfacial polymerization method, and an in-liquid curing film method.

The amount of melamine resin is adjusted so that the capsule thickness is 0.1 to 1.0 μm. ) This is a method in which this is emulsified and dispersed in a solution of a curing agent dissolved in a diluent, heated to 50° C. while stirring, ethylene chloride is volatilized out of the system, and microencapsulated powder is obtained by filtration and drying.

Particularly in semiconductor encapsulation applications, it is expected that plastic packaging will become more common in the future, and for this reason, it is desired that both curability and storage stability at room temperature be achieved.The industrial significance of the present invention is therefore very large.
