INORGANIC REINFORCED POLYAMIDE RESIN COMPOSITION

WIPO Patent Application WO/2022/009690

A1

[Problem] To provide an inorganic reinforced polyamide resin composition which achieves a good balance between conflicting mechanical characteristics, namely between high stiffness and impact resistance (high toughness), while having excellent fluidity, and which additionally has excellent long-term wear resistance (high sliding properties) in cases where an inorganic fiber-reinforced material is used as a sliding counterpart member. [Solution] An inorganic reinforced polyamide resin composition which contains from 10% by mass to 55% by mass of a crystalline polyamide resin (A), from 1% by mass to 20% by mass of an amorphous polyamide resin (B), from 40% by mass to 70% by mass of an inorganic reinforcing material (C) and from 0.5% by mass to 10% by mass of a modified polyolefin resin (D) having a reactive functional group that is reactive with a terminal group and/or a main chain amide group of a polyamide resin, said inorganic reinforced polyamide resin composition being characterized in that: the blending mass ratio of the component (D) to the component (A) satisfies 0.01 ≤ (D)/(A) ≤ 0.2; and the blending mass ratio of the component (B) to the component (A) satisfies 0.05 ≤ (B)/(A) ≤ 0.7.
