Title
(EN) POLYAMIDE RESIN COMPOSITION AND METHOD FOR PRODUCING SAME
(FR) COMPOSITION DE RÉSINE POLYAMIDE ET PROCÉDÉ DE PRODUCTION D’UNE TELLE COMPOSITION
(JA) ポリアミド樹脂組成物、及びその製造方法
Abstract
(EN)
A polyamide resin composition containing (A) a crystalline polyamide resin having a polycapramide resin as the main component, (B) a semi-aromatic amorphous polyamide resin, (C) an inorganic reinforcing material, (D) a carbon black master batch, and (E) a copper compound, wherein: the polyamide resin composition includes (C-1) glass fibers, (C-2) acicular wollastonite, and (C-3) an inorganic reinforcing material of plate-like crystals as the (C) inorganic reinforcing material; the melt mass flow rate and the cooling crystallization temperature (TC2) of the polyamide resin composition are within specific ranges; the mass ratio and content amount of each component satisfy specific conditions; and the polyamide resin composition not only yields a molded article having a higher level of appearance, but also exhibits exceptional weather resistance of the appearance of the molded article surface, through use of a mold temperature of 100°C or lower during molding.
(FR)
L’invention concerne une composition de résine polyamide contenant (A) une résine polyamide cristallin présentant une résine polycapramide en tant que constituant principal, (B) une résine polyamide amorphe semi-aromatique, (C) un matériau de renforcement inorganique, (D) un mélange maître de noir de carbone, et (E) un composé de cuivre. La composition de résine polyamide comprend (C-1) des fibres de verre, (C-2) de la wollastonite aciculaire, et (C-3) un matériau de renforcement inorganique de cristaux lamellaires en tant que (C) matériau de renforcement inorganique ; le débit massique en fusion et la température de cristallisation de refroidissement (TC2) de la composition de résine polyamide sont compris dans des plages spécifiques ; le rapport massique et la teneur quantitative de chaque constituant satisfaisant à des conditions spécifiques ; et la composition de résine polyamide produit non seulement un article moulé ayant un plus bel aspect, mais présente également une résistance aux intempéries exceptionnelle de l'aspect de la surface d'article moulé, grâce à l'utilisation d'une température de moule inférieure ou égale à 100 °C pendant le moulage.
(JA)
(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、(C)無機強化材、(D)カーボンブラックのマスターバッチ、及び(E)銅化合物を含有するポリアミド樹脂組成物であって、(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、及び(C-3)板状晶の無機強化材を含み、ポリアミド樹脂組成物のメルトマスフローレイト及び降温結晶化温度(TC2)が特定の範囲内にあり、各成分の質量比、含有量が特定の条件を満たすポリアミド樹脂組成物であり、成形時の金型温度が100℃以下でより高いレベルの外観の成形品が得られるのみならず、成形品表面の外観の耐侯性が優れたポリアミド樹脂組成物である。
