Definitions
- the present invention relates to a halogen-free flame retardant polyamide composition.
- a polyamide resin that can be molded into a predetermined shape by heating and melting has been used as a material for forming an electronic component.
- Widely used polyamides include aliphatic polyamides such as 6 nylon and 66 nylon.

Does not have.
- 46 nylon was developed as a polyamide having high heat resistance.
- 46 nylon has a problem that the water absorption rate is high. Therefore, the dimensions of electrical and electronic parts molded using the 46 nylon resin composition may change due to water absorption. If the molded body absorbs water, problems such as blistering, so-called blistering, occur due to heating in the reflow soldering process.
- the surface mounting method using lead-free solder is being shifted. Lead-free solder has a higher melting point than conventional lead solder. Accordingly, the mounting temperature has inevitably increased by 10 to 20 ° C., and the use of 46 nylon has become difficult.
- Aromatic polyamides derived from aromatic dicarboxylic acids such as terephthalic acid and aliphatic alkylenediamines have been developed.
- Aromatic polyamide is more excellent in heat resistance and low water absorption than aliphatic polyamide such as 46 nylon.

本発明の難燃性ポリアミド組成物は強化材(D)を含有してもよく、繊維状、粉状、粒状、板状、針状、クロス状、マット状などの形状を有する種々の無機充填材を使用することができ、単独あるいは複数のものと併用して使用することが可能である。さらに詳述すると、シリカ、シリカアルミナ、炭酸カルシウム、二酸化チタン、タルク、ワラストナイト、ケイソウ土、クレー、カオリン、球状ガラス、マイカ、セッコウ、ベンガラなどの粉状あるいは板状の無機化合物;チタン酸カリウムなどの針状の無機化合物;ガラス繊維(グラスファイバー)、チタン酸カリウム繊維、金属被覆ガラス繊維、セラミックス繊維、ワラストナイト、炭素繊維、金属炭化物繊維、金属硬化物繊維、アスベスト繊維およびホウ素繊維などの無機繊維;さらにはアラミド繊維、炭素繊維のような有機繊維が、強化材(D)として挙げられる。強化材(D)は、なかでも繊維状物質が好ましく、より好ましくはガラス繊維が挙げられる。
本発明の難燃性ポリアミド組成物は、金属水酸化物(E-1)および金属酸化物(E-2)から選ばれる金属化合物成分を含有していてもよく、好ましくは金属酸化物(E-2)を含有する。これらを含有することで、ポリアミド組成物による鋼材の腐食磨耗を、より抑制することができる。金属水酸化物(E-1)および金属酸化物(E-2)は、単独または複数の化合物を併用することができる。
本発明の難燃性ポリアミド組成物は、上記各成分に加えて、本発明の目的を損なわない範囲で、上記以外の難燃助剤、難燃剤、酸化防止剤、ラジカル捕捉剤、耐熱安定剤、耐候安定剤、流動性向上剤、可塑剤、増粘剤、帯電防止剤、離型剤、顔料、染料、無機あるいは有機充填剤、核剤、繊維補強剤、カーボンブラック、タルク、クレー、マイカ等無機化合物などの、種々公知の配合剤を含有していてもよい。また、本発明の難燃性ポリアミド組成物は、通常用いられるイオン捕捉剤などの添加剤を含有してもよい。イオン捕捉剤としては、例えばハイドロタルサイト、ゼオライトが知られている。特に本発明の難燃性ポリアミド組成物は、上記のうち繊維補強剤を含有していることにより、より一層耐熱性、難燃性、剛性、引張強度、曲げ強度、衝撃強度が向上される。
本発明のポリアミド組成物は、前述のポリアミド樹脂(A)と、難燃剤(C)とを必須成分として含みつつ、ポリアミド樹脂(A)以外の熱可塑性樹脂(B)を必須成分として含むかどうかで、二つの態様に大別される。
本発明の第一の難燃性ポリアミド組成物は、前述の熱可塑性樹脂(B)を必須成分として含むことを特徴とする。
本発明の第二の難燃性ポリアミド組成物は、ポリアミド組成物の総量に対して、ポリアミド樹脂(A)を20~80質量%、好ましくは35~60質量%の割合で含むことが好ましい。第二の難燃性ポリアミド組成物中のポリアミド樹脂(A)の含有量が20質量%以上であると、十分な靭性を得ることができ;また、80質量%以下であると十分な難燃剤を含むことができ、難燃性を得ることができる。
本発明の難燃性ポリアミド組成物は、前記の各成分を公知の樹脂混練方法を用いて製造することができる。例えば前記の各成分を、ヘンシェルミキサー、Vブレンダー、リボンブレンダー、タンブラーブレンダーなどで混合する方法;あるいは、混合後さらに一軸押出機、多軸押出機、ニーダー、バンバリーミキサーなどで溶融混練後、造粒あるいは粉砕する方法を採用することができる。
本発明の難燃性ポリアミド組成物は、圧縮成形法、射出成形法、押出成形法などの公知の成形法を利用することにより、各種成形体に成形することができる。特に、射出成形法が好適で、窒素、アルゴン、ヘリウムに代表される不活性ガスの雰囲気下、具体的には例えば0.1~10ml/分の流量下で成形することで、成形機のシリンダー、スクリュー等の鋼材の腐食磨耗をさらに低減させることが可能となる。
[極限粘度[η]]
JIS K6810-1977に準拠して、ポリアミド樹脂0.5gを96.5%硫酸溶液50mlに溶解し、ウベローデ粘度計を使用し、25±0.05℃の条件下で試料溶液の流下秒数を測定した。測定結果から、以下の式に基づいてポリアミド樹脂の極限粘度[η]を算出した。
[η]=ηSP/[C(1+0.205ηSP)]
ηSP=(t-t0)/t0
[η]:極限粘度(dl/g)
ηSP:比粘度、C:試料濃度(g/dl)
t:試料溶液の流下秒数(秒)
t0:ブランク硫酸の流下秒数(秒)
ポリアミド樹脂の試料を、PerkinElemer社製DSC7を用いて加熱し、一旦330℃で5分間保持し、次いで10℃/分の速度で23℃まで降温せしめた後、10℃/分で昇温した。このときの融解に基づく吸熱ピークをポリアミド樹脂の融点とした。

上記流動長の測定時に、成形時のガス発生量を目視で評価した。ガス発生量がないものを○、若干ガス発生が見受けられたものを△、ガス発生量が多く使用に問題があるもの、または樹脂が分解して成形に問題があるものを×と評価した。樹脂組成物の熱安定性に優れるものは、ガス発生量が少なく金型汚染が良好となるため、成形性が良好であると判断される。
