Description
本発明において、特定の難燃剤を使用することにより、従来の過量の液体ゴムを添加することによる耐熱性が不良となる問題を解決できる。難燃剤を添加した後でも、樹脂材料の誘電特性が不良(高比誘電率、高誘電正接)となる問題を起こさない。換言すると、樹脂材料に本発明の特定の難燃剤を添加することによって、良好な難燃性及び誘電特性を両立することができる。
本発明の樹脂組成物は、液体ゴム2重量%~40重量%と、ポリフェニレンエーテル樹脂5重量%~60重量%と、架橋剤3重量%~40重量%と、リン系難燃剤5重量%~40重量%と、を含む。リン系難燃剤の構造は、式(I)で表される。
無機フィラーの添加により、樹脂材料の粘度を低減させ、且つ樹脂材料の比誘電率を低減させることができる。一部の種類の無機フィラーは、樹脂材料の熱導電性を向上させることもあるが、上述した説明は概に説明したものであり、本発明はこれに制限されるものではない。
樹脂材料は、シロキサンカップリング剤を更に含んでもよい。シロキサンカップリング剤の添加は、繊維布、樹脂組成物及び無機フィラーの間の反応性及び相容性を向上させ、金属基板の剥離強度及び耐熱性を向上させることができる。
樹脂材料は、触媒を更に含んでもよい。触媒は、樹脂材料の硬化を促進させて高周波基板を形成する、という役割を果たせる。樹脂組成物の総重を100重量部として、触媒の含有量は、0.1重量部~1重量部である。
本発明の樹脂材料が高周波基板材料として用いられることを証明するため、本発明において、液体ゴム2重量%~40重量%と、ポリフェニレンエーテル樹脂5重量%~60重量%と、ビスマレイミド樹脂5重量%~30重量%と、架橋剤3重量%~40重量%と、リン系難燃剤5重量%~40重量%とを混合することによって、樹脂組成物を形成した上で、樹脂組成物に無機フィラーを配合した。それによって、実施例1~4及び比較例1~10に係る樹脂材料を形成した。実施例1~4及び比較例1~10における樹脂材料の成分比について、表1に示すとおりである。実施例1~4及び比較例1~10における樹脂材料のガラス転移温度、比誘電率及び誘電正接については、表2に示すとおりである。
(1)ガラス転移温度:動的機械分析装置(Dynamic Mechanical Analyzer,DMA)を用いて樹脂材料のガラス転移温度を測定する。
(2)比誘電率(10GHz):誘電分析装置(Dielectric Analyzer)(品番:HP Agilent E4991A)を用いて、樹脂材料の10GHzの周波数での比誘電率を測定する。
(3)誘電正接(10GHz):誘電分析装置(Dielectric Analyzer)(品番:HP Agilent E4991A)を用いて、樹脂材料の10GHzの周波数での誘電正接を測定する。
(4)剥離強度:試験方法IPC-TM-650-2.4.8に基づいて、金属基板の剥離強度を測定する。
(5)耐熱性:圧力鍋において温度120℃、圧力2atmで金属基板を120分加熱して、288℃のはんだ付け炉に浸し、基板がポップコーンするまでにかかる時間を記録する。ポップコーンするまでにかかる時間は10分間を超えると、「OK」を示す。ポップコーンするまでにかかる時間は10分間より少ないと、「NG」を示す。
本発明の有利な効果として、本発明に係る樹脂材料及び金属基板は、「リン系難燃剤5~40重量%」、「リン系難燃剤の構造は、式(I)で表される」といった技術特徴により、良好な耐熱性及び誘電特性の利点を有する。
