【発明の詳細な説明】
（産業上の利用分野）
本発明はポリアミドを主体とした機械的強度、特に耐衝
撃性の改良された樹脂組成物に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a resin composition containing polyamide as a main component and having improved mechanical strength, particularly impact resistance.
（従来技術および問題点）

動車、電気機器部品等の成形品として広く用いられてい
る。(Prior Art and Problems) Polyamide has excellent mechanical strength, chemical resistance, and oil resistance, and is widely used as molded products for automobiles, electrical equipment parts, etc.
しかし、成形品にあとから金属棒又はケーブル等を圧入
し、固定りるクランプ、ブツシュ、ファスナー等の用途
に見られる様に、剛性と耐衝撃性が要求される分野にお

イロン１２等通常一般に使用されるポリアミドの耐衝撃
性は充分では無く、装着時に割れる等の問題を生じる欠
点があった。However, in fields where rigidity and impact resistance are required, such as in applications such as clamps, bushings, and fasteners in which metal rods or cables are press-fitted into molded products and then fixed, nylon 6, nylon Polyamides commonly used, such as 66, nylon 11, and nylon 12, do not have sufficient impact resistance and have the disadvantage of causing problems such as cracking when installed.
このため耐！Ｉ撃性を改良する方法としては、可塑剤や
ゴム等を添加することが行なわれている。For this reason, be patient! Addition of plasticizers, rubber, etc. has been used to improve the impact resistance.
しかし、耐衝撃性を改良するためには可塑剤を多量に添

剛性を損うばかりか、可塑剤のブリードによる物性の変
化を生じる。ゴム等の添加は、耐Ｗａ性の改良効果が充
分でないだけでなく、居間剥離等の問題を生じ易い。However, in order to improve impact resistance, it is necessary to add a large amount of plasticizer, which not only impairs the rigidity that iron-free iron originally has, but also causes changes in physical properties due to plasticizer bleeding. Addition of rubber or the like not only does not have a sufficient effect of improving Wa resistance, but also tends to cause problems such as peeling.
本発明者はかかる問題点を解決すべく鋭意検討を行なっ
た結果、ポリアミドエラストマーに無機強化充填剤を配

され、しかも経時的な物性変化が少なく、層間剥離など
の問題のない樹脂組成物の得られることを見い出し、こ
の知見に基づいて本発明をなずに至った。The inventors of the present invention have conducted extensive studies to solve these problems, and have found that by blending an inorganic reinforcing filler into a polyamide elastomer, impact resistance is improved without impairing rigidity, and physical properties change over time. It has been found that a resin composition can be obtained that has a small amount of delamination and is free from problems such as delamination, and based on this knowledge, the present invention has been completed.
