Therefore, if this thermoplastic resin composition is used for a long object fixing jig, it becomes possible to shorten the molding cycle when the fixing jig is molded, and the bending resistance and the strength of the joint portion are improved under actual use. While increasing, the confirmation of the fitting sound when inserting a band part in a latching | locking part can be made easy.
本発明の熱可塑性樹脂組成物には、成形時の冷却固化時間を短縮しハイサイクル性を改良する目的と、大気平衡時の弾性率を改良する目的で無機核剤（ｃ）を添加する。無機核剤（ｃ）の具体例としては、タルク、ワラステナイト、ゼオライト、セリサイト、マイカ、カオリン、クレー、パイロフィライト、ベントナイト、アスベスト、アルミナシリケートなどの珪酸塩、モンモリロナイト、合成雲母などの膨潤性の層状珪酸塩、酸化珪素、酸化マグネシウム、アルミナ、酸化ジルコニウム、酸化チタン、酸化鉄などの金属化合物、炭酸カルシウム、炭酸マグネシウム、ドロマイトなどの炭酸塩、硫酸カルシウム、硫酸バリウムなどの硫酸塩、水酸化カルシウム、水酸化マグネシウム、水酸化アルミニウムなどの水酸化物、ガラスビーズ、ガラスフレーク、ガラス粉、セラミックビーズ、窒化ホウ素、炭化珪素、カーボンブラックおよびシリカ、黒鉛、紙粉、木粉、竹粉、セルロース粉末、籾殻粉末、果実殻粉末、キチン粉末、キトサン粉末、タンパク質、澱粉、籾殻、木材チップ、おから、古紙粉砕材、衣料粉砕材などが挙げられる。中でもタルクが好ましい。これらは中空であってもよく、さらにはこれら無機核剤を２種類以上併用することも可能である。また、これらの無機核剤はその表面を公知のカップリング剤（例えば、シラン系カップリング剤、チタネート系カップリング剤など）、その他の表面処理剤および膨潤性の層状珪酸塩では有機化オニウムイオンで予備処理することは、より優れたハイサイクル性、機械的強度を得る意味において好ましい。 The thermoplastic resin composition of the present invention, you added and purpose of improving the shortened high-cycle properties of the cooling and solidification time during molding, the inorganic nucleating agent for the purpose of improving the elastic modulus at atmospheric equilibrium (c) . Specific examples of the inorganic nucleating agent (c) include swelling of silicates such as talc, wollastonite, zeolite, sericite, mica, kaolin, clay, pyrophyllite, bentonite, asbestos, and alumina silicate, montmorillonite, and synthetic mica.

無機核剤（ｃ）の配合割合はポリアミド樹脂（ａ）とポリ乳酸樹脂（ｂ）の合計１００重量部に対して、０．０１〜１０重量部である。好ましくは０．１〜５重量部であるとよい。０．０１重量部未満の添加量においてはハイサイクル性と大気平衡時の弾性率の改良効果が小さく、１０重量部を超える場合は靭性の低下が著しくなる。 The compounding ratio of the inorganic nucleating agent (c) is 0.01 to 10 parts by weight with respect to 100 parts by weight as a total of the polyamide resin (a) and the polylactic acid resin (b) . Good Mashiku may If it is 0.1 to 5 parts by weight. Small effect of improving the high-cycle properties and elastic modulus at atmospheric equilibrium in amount of less than 0.01 part by weight, when it exceeds 10 parts by weight decreases toughness significantly ing.
