Description

本発明は、耐熱性、電気特性に優れるジヒドロベンゾキサジン樹脂をより低温で硬化させることのできる熱硬化性樹脂組成物、その成形体、硬化体、硬化成形体、並びにそれらを含む電子機器に関する。   The present invention relates to a thermosetting resin composition capable of curing a dihydrobenzoxazine resin having excellent heat resistance and electrical properties at a lower temperature, a molded body, a cured body, a cured molded body, and an electronic device including the same. .

従来から、フェノール樹脂、メラミン樹脂、エポキシ樹脂、不飽和ポリエステル樹脂、ビスマレイミド樹脂等の熱硬化性樹脂は、その熱硬化性という性質に基づき、耐水性、耐薬品性、耐熱性、機械強度、信頼性等が優れているので広い産業分野で使用されている。   Conventionally, thermosetting resins such as phenol resin, melamine resin, epoxy resin, unsaturated polyester resin, bismaleimide resin are based on their thermosetting properties, water resistance, chemical resistance, heat resistance, mechanical strength, It has excellent reliability and is used in a wide range of industrial fields.

しかし、フェノール樹脂及びメラミン樹脂は硬化時に揮発性の副生成物を発生する、エポキシ樹脂及び不飽和ポリエステル樹脂は難燃性が劣る、ビスマレイミド樹脂は非常に高価である等の欠点がある。   However, the phenol resin and the melamine resin generate volatile by-products upon curing, the epoxy resin and the unsaturated polyester resin are inferior in flame retardancy, and the bismaleimide resin is very expensive.

これらの欠点を解消するために、ジヒドロベンゾキサジン環が開環重合反応し、問題となるような揮発分の発生を伴わずに熱硬化するジヒドロベンゾキサジン化合物(以下、ベンゾキサジン化合物と略することもある)が研究されてきた。ベンゾキサジン化合物は、上記のような熱硬化性樹脂が有する基本的な特徴に加え、保存性に優れており、溶融時には比較的低粘度であり、分子設計の自由度が広い等の様々な利点を有する樹脂である。このようなベンゾキサジン化合物としては、例えば、特開昭49−47378号公報等に開示されている(特許文献1)。   In order to eliminate these drawbacks, a dihydrobenzoxazine ring undergoes a ring-opening polymerization reaction and is thermally cured without generation of a volatile matter causing a problem (hereinafter abbreviated as a benzoxazine compound). Have been studied). In addition to the basic characteristics of the thermosetting resin as described above, the benzoxazine compound has excellent storability, a relatively low viscosity when melted, and various advantages such as a wide degree of freedom in molecular design. It is resin which has. Such a benzoxazine compound is disclosed in, for example, JP-A-49-47378 (Patent Document 1).

また、非特許文献1では、ビスフェノールS型のベンゾキサジン化合物が、一般的なオキサジン化合物に比べて、熱硬化温度が低いことが開示されている。ただし、この化合物は、誘電特性はよくない。   Non-Patent Document 1 discloses that a bisphenol S-type benzoxazine compound has a lower thermosetting temperature than a general oxazine compound. However, this compound has poor dielectric properties.

また、非特許文献2では、種々のビスフェノール型ベンゾキサジン化合物について検討し、電子吸引基のついたビスフェノール、特にビスフェノールS型のベンゾキサジン化合物が最も硬化温度が低いことが開示されている。   Non-Patent Document 2 examines various bisphenol-type benzoxazine compounds, and discloses that bisphenols with electron-withdrawing groups, particularly bisphenol S-type benzoxazine compounds, have the lowest curing temperature.

一般的にベンゾオキサジンは硬化温度が高いが、電子材料用途で多用されているエポキシ樹脂と同等のプロセス温度までは、低温化することが望まれている。上記のビスフェノールS型ベンゾキサジン化合物では、アミン側でしか特性を調整できず、低誘電率化、靭性向上等の要求に応えられない。   In general, benzoxazine has a high curing temperature, but it is desired to lower the temperature to a process temperature equivalent to that of an epoxy resin that is frequently used for electronic materials. In the bisphenol S-type benzoxazine compound, the characteristics can be adjusted only on the amine side, and it is not possible to meet the demands for lowering the dielectric constant and improving toughness.

また、通常硬化促進剤はフェノール類あるいはカルボン酸をはじめとする酸類がよく知られているが、例えば、非特許文献3では、フェノール性OHを有するp−クレゾールとカルボキシル基を有するセバシン酸と比較により、p−クレゾールの方が触媒としての効果が高いと述べられている。ただし、フェノール類の中での優劣については特に知られていない。

In general, curing accelerators are well known as phenols or acids such as carboxylic acids. For example, in Non-Patent Document 3, p-cresol having phenolic OH and sebacic acid having a carboxyl group are compared. Therefore, it is stated that p-cresol is more effective as a catalyst. However, it is not particularly known about superiority or inferiority among phenols.
