本発明の半芳香族ポリアミド樹脂組成物は、半芳香族ポリアミド(A)と白色顔料(B)とを含有し、半芳香族ポリアミド(A)は、芳香族ジカルボン酸成分と脂肪族ジアミン成分とモノカルボン酸成分とから構成される。
分子量が140以上の脂肪族モノカルボン酸としては、カプリル酸、ノナン酸、デカン酸、ラウリン酸、ミリスチン酸、パルミチン酸、ステアリン酸、ベヘン酸が挙げられる。中でも、汎用性が高いことから、ステアリン酸が好ましい。

酸化防止剤は、通常、半芳香族ポリアミド(A)の分子量低下や色の退化防止を目的に含有させるものである。本発明においては、これらの効果に加えて、樹脂組成物の滞留安定性を向上させることができる。すなわち、繊維状強化材(C)を含有する半芳香族ポリアミド樹脂組成物は、高温のシリンダー内に長時間滞留した場合、繊維状強化材(C)の表面処理剤が熱分解し、機械的強度の低下を引き起こす場合がある。しかしながら、酸化防止剤を含有することにより、シリンダー内で長時間樹脂組成物を滞溜させた場合、すなわち、射出成形時において成形サイクルが長い場合や射出量が少なくシリンダー内に樹脂が長く滞留する場合でも、樹脂組成物の引張強度の低下を抑制することができる。
市販のリン系酸化防止剤としては、例えば、アデカ社製“アデカスタブ”PEP-8、PEP-36、PEP-4C、クラリアント社製“ホスタノックス”P-EPQが挙げられる。
市販のヒンダードフェノール系酸化防止剤としては、例えば、アデカ社製“アデカスタブ”AO-20、AO-30、AO-40、AO-50、AO-60、AO-70、AO-80、AO-330、チバスペシャリティケミカル社製“イルガノックス”245、259、565、1010、1035、1076、1098、1222、1330、1425、1520、3114、5057、住友化学工業社製“スミライザー”BHT-R、MDP-S、BBM-S、WX-R、NW、BP-76、BP-101、GA-80、GM、GS、サイアナミド社製“サイアノックス”CY-1790が挙げられる。
市販の硫黄系酸化防止剤としては、例えば、住友化学工業社製“スミライザー”TP-Dが挙げられる。
市販の光安定剤としては、例えば、クラリアントジャパン社製“ナイロスタブ”S-EED、共同薬品社製“バイオソーブ”04、チバ・スペシャリティ・ケミカルズ社製“チヌビン”622、765、Cytec社製“サイアソーブ”UV-3346、旭電化工業社製“アデカスタブ”LA-57、BASF社製“チマソーブ”119、944が挙げられる。
市販の蛍光増白剤としては、例えば、チバスペシャリティケミカル社製“チノパール”OB、クラリアント社製“ホスタノックス”KS、イーストマン社製“イーストブライト”OB-1が挙げられる。
射出成形機としては、特に限定されず、例えば、スクリューインライン式射出成形機、プランジャ式射出成形機が挙げられる。
射出成形機のシリンダー内で加熱溶融された半芳香族ポリアミド樹脂組成物は、ショットごとに計量され、金型内に溶融状態で射出され、所定の形状で冷却、固化された後、成形体として金型から取り出される。射出成形時の樹脂温度は、半芳香族ポリアミド樹脂組成物の融点以上とする必要があり、(融点+100℃)未満とすることが好ましい。
なお、半芳香族ポリアミド樹脂組成物の加熱溶融時には、用いる半芳香族ポリアミド樹脂組成物は十分に乾燥されたものを用いることが好ましい。含有する水分量が多いと、射出成形機のシリンダー内で樹脂が発泡し、最適な成形体を得ることが困難となることがある。射出成形に用いる半芳香族ポリアミド樹脂組成物の水分率は、0.3質量%未満が好ましく、0.1質量%未満がより好ましい。
また、本発明の樹脂組成物を構成する半芳香族ポリアミド(A)は、ポリアミド6、ポリアミド66に比べ、融点が高く、成形体を得るための溶融温度が高いため、樹脂が長時間にわたって成形機シリンダー内に滞留する場合、前記樹脂が劣化しやすく、分解ガスが発生しやすい。したがって、本発明の半芳香族ポリアミド樹脂組成物を成形して耐熱性に優れた成形体を得るためには、成形サイクルを短くし、溶融樹脂の成形機シリンダー内への滞留を極力抑制することが好ましい。

W=100-〔(100-L)2+a2+b2〕1/2

実用上、処理前の反射率は85%以上が好ましく、90%以上がより好ましく、処理後の反射率は、60%以上が好ましく、70%以上がより好ましく、80%以上がさらに好ましい。
反射率の保持率は、以下の式を用いて求めた。
保持率=([処理後の反射率]/[処理前の反射率])×100
ファナック社製射出成形機S2000i-100Bを用いて、シリンダー温度を(融点+25℃)、金型温度を(融点-185℃)に設定した後、型締力100トン、射出圧力120MPa、射出速度80mm/秒、射出時間5秒の条件で、片側1点ゲートの専用金型を取り付けて成形をおこなった。専用金型は、厚さ0.4mm、幅20mmのL字状の成形品が採取できる形状で、流動長は最大150mmであった。流動長が長いほど、流動性に優れていることを意味する。
金型内にセットされたリードフレームに、半芳香族ポリアミド樹脂組成物を射出成形し、反射板を作製し、次いで、半導体発光素子としてInGaN系青色からなる青色LED素子を、銀ペーストを用いて固定した。金線を取り付け、その後、透明封止樹脂を注入し、150℃、1時間加熱し、硬化させ、図1に示す表面実装型LEDパッケージを得た。図1において、1は反射板、2はリードフレーム、3は金線、4は透明封止樹脂、5は半導体発光素子を示す。

芳香族ジカルボン酸成分として粉末状のテレフタル酸(TPA)4.70kgと、モノカルボン酸として分子量284のステアリン酸(STA)0.32kgと、重合触媒として次亜リン酸ナトリウム一水和物9.3gとを、リボンブレンダー式の反応装置に入れ、窒素密閉下、回転数30rpmで撹拌しながら170℃に加熱した。その後、温度を170℃に保ち、かつ回転数を30rpmに保ったまま、液注装置を用いて、脂肪族ジアミン成分として100℃に加温した1,10-デカンジアミン(DDA)4.98kgを、2.5時間かけて連続的(連続液注方式)に添加し反応物を得た。
その後、得られた反応物を、同じ反応装置で、窒素気流下、250℃、回転数30rpmで8時間加熱して重合し、ストランド状に引き取った後、水槽に通して冷却固化し、それをペレタイザーでカッティングして半芳香族ポリアミド(P-1)ペレットを得た。
表1に示す樹脂組成になるように各成分の種類や配合量を変更した以外は、製造例1と同様にして半芳香族ポリアミドペレット(P-2~P-17)を得た。
同方向二軸押出機(東芝機械社製TEM26SS、スクリュー径26mm、L/D49)の主供給口に、クボタ社製ロスインウェイト式連続定量供給装置CE-W-1を用いて計量した半芳香族ポリアミド(P-1)100質量部、白色顔料(TI)40質量部、酸化防止剤(AO-1)0.5質量部、光安定剤(LS)0.5質量部、蛍光増白剤(FB)0.1質量部を供給し、サイドフィーダーより繊維状強化材(GF-1)を25質量部供給し、溶融混練をおこなった。溶融温度は320℃~340℃、スクリュー回転数は250rpm、吐出量は35kg/時間であった。その後、ストランド状に引き取った後、水槽に通して冷却固化し、それをペレタイザーでカッティングして半芳香族ポリアミド樹脂組成物を得た。
表2および表3に示す種類、含有量になるように樹脂組成を変更した以外は、実施例1と同様にして半芳香族ポリアミド樹脂組成物を得た。なお、ガラス繊維はサイドフィーダーから、その他は主供給口から供給した。
白色含量の含有量を変更した以外は、実施例1と同様の操作をおこなったが、白色顔料の含有量が高かったため、ストランドが切断し、半芳香族ポリアミド樹脂組成物を得ることができなかった。
白色顔料として酸化チタン、炭酸カルシウム、硫酸バリウムのうちの2種を併用した実施例26、27では、酸化チタンのみを用いた実施例25と比較して、反射率の保持率の向上がみられた。また、金属水酸化物(水酸化マグネシウム)を含有した実施例31においても、金属水酸化物を含有しない実施例1と比較して、反射率の保持率の向上がみられた。
比較例3は、半芳香族ポリアミド中のモノカルボン酸の含有量が本発明で規定する範囲よりも少なかったため、成形流動性が低下し、流動長が短かった。比較例4は、半芳香族ポリアミド中のモノカルボン酸の含有量が本発明で規定する範囲よりも多かったため、曲げ強度が低かった。
比較例5は、半芳香族ポリアミド中のモノカルボン酸として、分子量が140未満のカプロン酸を用いたため、成形流動性向上効果が乏しく、流動長が短かった。
比較例6は、半芳香族ポリアミド中のモノカルボン酸として、分子量が140未満の安息香酸を用いたため、比較例5と同様に、流動長が短かった。また、耐リフロー性にも劣っていた。
比較例7において安息香酸の含有量を増やして相対粘度を下げた半芳香族ポリアミドを使用したところ、流動長は長くなったが、耐リフロー性は劣ったままであった。また、実施例1と対比して、モノカルボン酸の含有量はほぼ同じにもかかわらず、処理前の反射率が低く、反射率の保持率も低かった。
