Description

本発明は、低誘電特性、耐熱性、耐燃性に優れる硬化物が得られる硬化性樹脂組成物に関するものであり、該硬化性樹脂組成物を硬化させた硬化物に関する。本発明の硬化性樹脂組成物およびその硬化物はプリント配線板用樹脂、半導体用封止樹脂、半導体用層間絶縁材料、電子部品の絶縁材料等の電子材料の分野で好適に使用される。 The present invention relates to a curable resin composition from which a cured product excellent in low dielectric properties, heat resistance and flame resistance can be obtained, and to a cured product obtained by curing the curable resin composition. The curable resin composition of the present invention and the cured product thereof are suitably used in the field of electronic materials such as printed wiring board resins, semiconductor sealing resins, semiconductor interlayer insulating materials, and electronic component insulating materials.

従来、硬化性樹脂は、接着、注型、コーティング、含浸、積層、成形コンパウンドなど幅広く利用されている。しかしながら、その用途は多岐にわたり、使用環境や使用条件によっては、従来から知られている硬化性樹脂では満足できない場合がある。
情報通信・計算機の分野においては、例えば、PHS、携帯電話等の情報通信機器の信号帯域、コンピューターのCPUクロックタイムはGHz帯に達し、絶縁体による電気信号の減衰を抑制するために絶縁体には誘電率及び誘電正接の小さな材料が求められている。これらの材料としては、フッ素系樹脂、ポリオレフィン系樹脂、ポリスチレン系樹脂、ポリフェニレンエーテル系樹脂、ビニルベンジルエーテル樹脂等が提案されている。(例えば特許文献1、2、3、4参照)。
一方、プリント配線板、半導体パッケージの分野においては、例えば、近年の鉛フリー半田の導入により半田実装時の温度が上昇し、より高い実装信頼性を確保するために、材料に対してより高い耐熱性が求められている。
さらに、これらに用いられる硬化性樹脂は適用製品の安全性の観点から難燃化が必須である。
Conventionally, curable resins have been widely used for adhesion, casting, coating, impregnation, lamination, molding compound, and the like. However, there are various uses, and depending on the use environment and use conditions, conventionally known curable resins may not be satisfactory.
In the field of information communications and computers, for example, the signal bandwidth of information communication equipment such as PHS and mobile phones, and the CPU clock time of computers reach the GHz band. Therefore, a material having a small dielectric constant and dielectric loss tangent is required. As these materials, fluorine resins, polyolefin resins, polystyrene resins, polyphenylene ether resins, vinyl benzyl ether resins and the like have been proposed. (See, for example, Patent Documents 1, 2, 3, and 4).
On the other hand, in the fields of printed wiring boards and semiconductor packages, for example, with the introduction of lead-free solder in recent years, the temperature during solder mounting rises, and in order to ensure higher mounting reliability, higher heat resistance to materials Sex is required.
Furthermore, the curable resin used for these is indispensable to flame retardance from the viewpoint of the safety of the applied product.

一般に、樹脂材料の難燃化は、構造中に臭素などのハロゲン化合物やリン原子を含有する赤リンや有機リン化合物、水酸化アルミニウムのような金属水酸化物を添加することによってなされている。
しかしながら、上記のような化合物を添加することで耐燃性を付与することはできるが、絶縁材料の誘電率、誘電正接を増加させ、耐熱性を低下させる傾向にあり、低誘電特性、耐熱性を維持したまま耐燃性を兼ね備えた材料が強く望まれている。
最近になって、低誘電特性と耐燃性を両立する硬化性樹脂組成物は報告されているが、硬化物の耐熱性に関しては深く議論されていない。(例えば特許文献5、6、7、8参照)。
In general, flame retarding of resin materials is achieved by adding halogen compounds such as bromine, red phosphorus or organic phosphorus compounds containing phosphorus atoms, and metal hydroxides such as aluminum hydroxide in the structure.
However, it is possible to impart flame resistance by adding a compound as described above, but it tends to increase the dielectric constant and dielectric loss tangent of the insulating material and lower the heat resistance, and has low dielectric properties and heat resistance. There is a strong demand for a material that maintains flame resistance while maintaining it.
Recently, a curable resin composition having both low dielectric properties and flame resistance has been reported, but the heat resistance of the cured product has not been deeply discussed. (For example, see Patent Documents 5, 6, 7, and 8).

一方、本発明者等は、上記低誘電特性、耐熱性の要求に応えるべく、2官能性フェニレンエーテルオリゴマーのビニル化合物誘導体を開発してきた(例えば特許文献9参照)。
該誘導体の硬化物は低誘電特性、耐熱性に優れるが、上記の電子材料用途に展開するためには、耐燃性を付与する必要がある。
耐燃性を付与する方法として、上記のような難燃剤の添加が挙げられるが、該誘導体に含まれるポリフェニレンエーテル骨格は耐燃性を示すことが知られており(例えば特許文献10)、そのため該誘導体の硬化物は従来の硬化性ビニル化合物に比べて、難燃剤の添加量が抑えられ、難燃剤添加による誘電率増大、誘電正接増大、耐熱性低下等の特性劣化を最小限に抑えることが期待される。
本発明者等は、該誘導体とハロゲン化合物、あるいは有機リン化合物を含有する積層板用樹脂組成物を報告しているが(特許文献11参照)、誘電正接が大きく、近年の電子材料分野のますますの高性能化の要請に対応するためには、満足すべきものとはいえない。

On the other hand, the present inventors have developed a vinyl compound derivative of a bifunctional phenylene ether oligomer in order to meet the low dielectric property and heat resistance requirements (see, for example, Patent Document 9).
The cured product of the derivative is excellent in low dielectric properties and heat resistance, but it is necessary to impart flame resistance in order to develop into the above-mentioned electronic material application.
As a method for imparting flame resistance, the addition of a flame retardant as described above can be mentioned. It is known that the polyphenylene ether skeleton contained in the derivative exhibits flame resistance (for example, Patent Document 10), and therefore the derivative is used. Compared to conventional curable vinyl compounds, the cured product can suppress the amount of flame retardant added and minimize the deterioration of properties such as increased dielectric constant, increased dielectric loss tangent and decreased heat resistance due to the added flame retardant. Is done.
The present inventors have reported a resin composition for laminates containing the derivative and a halogen compound or an organophosphorus compound (see Patent Document 11). However, the dielectric loss tangent is large, and the electronic material field in recent years is increasing. In order to meet the demand for higher performance, it is not satisfactory.
