前記ポリアミド樹脂組成物中のカルボキシル基量が120meq/kg未満であることを特徴とするポリアミド樹脂組成物。
[2] 前記ポリアミド樹脂組成物の、示差走査熱量計(DSC)で測定した降温結晶化温度が、下記式を満足する[1]に記載のポリアミド樹脂組成物。
180℃≦(TC2-1)≦185℃
(TC2-1)-(TC2-2)≦5℃
((TC2-1)は滞留0分のポリアミド樹脂組成物の降温結晶化温度を表し、(TC2-2)は280℃で20分滞留させたポリアミド樹脂組成物の降温結晶化温度を表す。)
[3] さらに、(D)カーボンブラックのマスターバッチ、及び(E)銅化合物を含有し、(A)、(B)、及び(C)の合計を100質量部としたとき、(D)の含有量が1~5質量部、(E)の含有量が0.001~0.1質量部である[1]または[2]に記載のポリアミド樹脂組成物。

本発明において、ポリアミド樹脂の結晶性/非晶性は、ポリアミド樹脂をJIS K 7121:2012に準じて昇温速度20℃/分でDSC測定した場合に、明確な融点ピークを示すものを結晶性、示さないものを非晶性とする。
本発明のポリアミド樹脂組成物中の各成分の含有量(配合量)は、特に但し書きをしない限り、(A)ポリカプラミド樹脂を主成分とする結晶性ポリアミド樹脂、(B)半芳香族非晶性ポリアミド樹脂、及び(C)無機強化材の合計を100質量部としたときの量で表している。
半芳香族非晶性ポリアミド樹脂の相対粘度(96%硫酸法)は、特に限定されるものではないが、好ましい範囲は1.8~2.4である。より好ましくは、1.9~2.2の範囲である。
0.35≦(B)/(A)≦0.80
本発明において、(B)/(A)がこの範囲にあることで、より高いレベルの良好な外観の成形品が得られ、(B)/(A)は、0.45以上、0.75以下が好ましく、0.55以上、0.75以下がより好ましい。
(C)成分は、いずれもポリアミド樹脂組成物中で補強効果を発揮するが、その中でも(C-1)ガラス繊維が、一番補強効果が高いが、成形品のソリ変形も大きい。(C-2)針状ワラストナイト、(C-3)板状晶の無機強化材は、ガラス繊維ほどの補強効果は無いものの、アスペクト比がガラス繊維よりも小さいため、ソリ変形が小さくなる利点がある。また、針状ワラストナイトは成形後のヒケ防止にも寄与でき、これらを適切に組み合わせることで、強化材が高濃度に配合されていても、成形後に大きな変形を生み出さない樹脂組成物を作製できる。
通常、ガラス繊維、ワラストナイトなどを高濃度に配合した強化ポリアミド樹脂組成物は、耐候性に劣り強化材の露出が発生するが、後述のカーボンブラックマスターバッチと銅化合物と組み合わせることにより耐候性を制御でき、強化材の露出を防ぐことが可能となる。
すなわち、(A)ポリカプラミド樹脂を主成分とする結晶性ポリアミド樹脂、(B)半芳香族非晶性ポリアミド樹脂、(D)カーボンブラックのマスターバッチおよび(E)銅化合物の分散液とを予め混合して押出機のホッパー部に投入し、(C)無機強化材として(C-1)ガラス繊維、(C-2)針状ワラストナイト、(C-3)板状晶の無機強化材をサイドフィード方式によって投入する製造方法である。銅化合物の分散液とは、銅化合物が溶媒に溶解した溶液も含む。

また、実施例8~10は、銅化合物とカーボンブラックを所定量組み合わせることにより、耐侯試験後の色差、強化材の露出、シボ状態においても非常に優れており、成形品表面の外観の耐久性、耐侯性が優れていることが分かる。一方、比較例4は、カルボキシル基量が規定外であるため、実施例8~10に比べて耐候性が良くない。
