Document Type and Number:
WIPO Patent Application WO/2020/153330
Kind Code:
A1
Abstract:
The present invention is a non-halogen-based flame retardant polyamide resin composition having both a high level of flame retardancy and excellent impact resistance and containing 25-60 parts by mass of a crystalline polyamide resin (A), 0-10 parts by mass of an amorphous polyamide resin (B), 0.1-10 parts by mass of a thermoplastic elastomer (C), 0.1-5 parts by mass of a salt (D) of an inorganic phosphorus compound, 5-20 parts by mass of a flame retardant agent combination (E), and 30-65 parts by mass of a reinforcing material (F), wherein the total of (A)-(F) is 100 parts by mass, the salt (D) of the inorganic phosphorus compound is the salt of piperazine and the inorganic phosphorus compound and/or the salt of melamine and the inorganic phosphorus compound, and the flame retardant agent combination (E) includes a metal salt (E1) of phosphinic acid, and a metal salt or double salt (E2) containing a phosphorous component and one or more metal components selected from the group consisting of alkaline-earth metals, transition metals, and aluminum.
