Description
本発明の一実施形態に係るプリプレグは、樹脂組成物又は前記樹脂組成物の半硬化物と、繊維質基材とを備える。このプリプレグ1は、図1に示すように、樹脂組成物又は前記樹脂組成物の半硬化物2と、樹脂組成物又は前記樹脂組成物の半硬化物2の中に存在する繊維質基材3とを備えるもの等が挙げられる。
本実施形態で用いる樹脂組成物は、前記変性ポリフェニレンエーテル化合物と、前記架橋型硬化剤とを含有する。
前記変性ポリフェニレンエーテル化合物は、炭素-炭素不飽和二重結合を有する置換基により末端変性された変性ポリフェニレンエーテル化合物であれば、特に限定されない。前記変性ポリフェニレンエーテル化合物としては、例えば、ポリフェニレンエーテル鎖を分子中に有し、炭素-炭素不飽和二重結合を有する置換基により末端変性された変性ポリフェニレンエーテル化合物等が挙げられる。
本実施形態で用いられる架橋型硬化剤は、炭素-炭素不飽和二重結合を分子中に有するものであれば、特に限定されない。すなわち、前記架橋型硬化剤は、前記変性ポリフェニレンエーテル化合物と反応させることによって、前記樹脂組成物内に架橋を形成させて、前記樹脂組成物を硬化させることができるものであればよい。前記架橋型硬化剤は、炭素-炭素不飽和二重結合を分子中に2個以上有する化合物が好ましい。
前記変性ポリフェニレンエーテル化合物の含有量は、前記変性ポリフェニレンエーテル化合物と前記架橋型硬化剤との合計100質量部に対して、40質量部以上であることが好ましく、40~90質量部であることがより好ましく、50~90質量部であることがさらに好ましい。すなわち、前記変性ポリフェニレンエーテル化合物は、前記変性ポリフェニレンエーテル化合物と前記架橋型硬化剤との合計質量に対して、40質量%以上であることが好ましい。また、前記架橋型硬化剤の含有量が、前記変性ポリフェニレンエーテル化合物と前記架橋型硬化剤との合計100質量部に対して、60質量部以下であることが好ましく、10~60質量部であることがより好ましく、10~50質量部であることがさらに好ましい。すなわち、前記変性ポリフェニレンエーテル化合物と前記架橋型硬化剤との含有比が、質量比で90:10~40:60であることが好ましく、90:10~50:50であることが好ましい。前記変性ポリフェニレンエーテル化合物及び前記架橋型硬化剤の各含有量が、上記比を満たすような含有量であれば、硬化物の耐熱性により優れた樹脂組成物になる。このことは、前記変性ポリフェニレンエーテル化合物と前記架橋型硬化剤との硬化反応が好適に進行するためと考えられる。
本実施形態に係る樹脂組成物は、本発明の効果を損なわない範囲で、必要に応じて、前記変性ポリフェニレンエーテル化合物及び前記架橋型硬化剤以外の成分(その他の成分)を含有してもよい。本実施の形態に係る樹脂組成物に含有されるその他の成分としては、例えば、シランカップリング剤、難燃剤、開始剤、消泡剤、酸化防止剤、熱安定剤、帯電防止剤、紫外線吸収剤、染料や顔料、滑剤、及び無機充填材等の添加剤をさらに含んでもよい。また、前記樹脂組成物には、前記変性ポリフェニレンエーテル化合物及び前記架橋型硬化剤以外にも、エポキシ樹脂等の熱硬化性樹脂を含有してもよい。
本実施形態で用いる樹脂組成物は、ワニス状に調製して用いてもよい。例えば、プリプレグを製造する際に、プリプレグを形成するための基材(繊維質基材)に含浸することを目的として、ワニス状に調製して用いてもよい。すなわち、樹脂組成物は、ワニス状に調製されたもの(樹脂ワニス)として用いてもよい。また、本実施形態で用いる樹脂組成物において、前記変性ポリフェニレンエーテル化合物及び前記架橋型硬化剤は、樹脂ワニス中に溶解されたものである。このようなワニス状の組成物(樹脂ワニス)は、例えば、以下のようにして調製される。
本実施形態で用いる繊維質基材は、石英ガラスクロスである。石英ガラスクロスは、石英ガラスヤーンからなるガラスクロスであって、ガラスクロスを構成するガラスが、二酸化ケイ素(SiO2)の含有率が99質量%以上の石英ガラス(Qガラス)である。石英ガラスクロスは、例えば、石英ガラス繊維を用いて製織することによって得られる。
前記プリプレグは、上述したように、炭素-炭素不飽和二重結合を分子中に有するシランカップリング剤を含む。前記シランカップリング剤は、プリプレグに含有していれば、その添加方法には限定されない。前記シランカップリング剤の添加方法としては、例えば、前記樹脂組成物を製造する際に、前記シランカップリング剤で予め表面処理した無機充填材を添加することによって、前記シランカップリング剤を添加してもよいし、前記シリカ及び前記シランカップリング剤をインテグラルブレンド法で添加してもよい。また、前記プリプレグを製造する際に、前記シランカップリング剤で予め表面処理した繊維質基材を用いることで、前記シランカップリング剤を前記プリプレグに添加してもよい。この中でも、前記シランカップリング剤で予め表面処理した無機充填材を添加する方法や前記シランカップリング剤で予め表面処理した繊維質基材を用いる方法が好ましい。すなわち、前記無機充填材としては、シランカップリング剤で予め表面処理された無機充填材が好ましく、前記繊維質基材としては、シランカップリング剤で予め表面処理された繊維質基材が好ましい。また、前記シランカップリング剤の添加方法としては、前記シランカップリング剤で予め表面処理した繊維質基材を用いる方法がより好ましく、前記シランカップリング剤で予め表面処理した無機充填材を添加する方法と前記シランカップリング剤で予め表面処理した繊維質基材を用いる方法とを併用する方法がさらに好ましい。すなわち、前記無機充填材としては、シランカップリング剤で予め表面処理された無機充填材を用い、前記繊維質基材としては、シランカップリング剤で予め表面処理された繊維質基材を用いることが好ましい。
前記プリプレグは、その硬化物の誘電正接が、10GHzにおいて、0.002以下である。前記プリプレグの硬化物の誘電正接は小さければ小さいほど好ましく、0であることが好ましい。このことから、前記プリプレグの誘電正接は、0~0.002であることが好ましく、0~0.0018であることがより好ましく、0~0.0016であることがさらに好ましい。プリプレグの硬化物の誘電正接が上記範囲内であると、低誘電特性に優れている。プリプレグの硬化物の誘電正接が上記範囲内になるように、樹脂組成物の組成、例えば、無機充填材及び開始剤等の含有量等を調整することが好ましい。
次に、本実施形態に係るプリプレグの製造方法について説明する。
