Abstract
A reinforced flame retardant resin composition including 20 to 87% by mass of an (A) thermoplastic resin, 3 to 20% by mass of a (B) aromatic phosphoric acid ester-based flame retardant agent, 5 to 40% by mass of (C) mica powder, and 0.5 to 30% by mass of (D) hydrous mineral powder having a dehydration starting temperature for crystallization water in a range of 400 to 600° C.
Claims14
A reinforced flame retardant resin composition comprising:
- 20 to 87% by mass of an (A) thermoplastic resin;
- 3 to 20% by mass of a (B) aromatic phosphoric acid ester-based flame retardant agent;
- 5 to 40% by mass of (C) mica powder;
- and
- 0.5 to 30% by mass of (D) chlorite group mineral powder having a dehydration starting temperature for crystallization water in a range of 400 to 600° C.
2 more elements
A method of increasing the flame retardance of a resin composition comprising:
- combining (D) chlorite group mineral powder having a dehydration starting temperature for crystallization water in a range of 400 to 600° C. with (A) a thermoplastic resin, (B) an aromatic phosphoric acid ester-based flame retardant agent, and (C) mica powder, wherein the flame retardance of the composition of (A), (B), (C), and (D) exhibits a higher flame retardance than a composition of (A), (B), and (C) that excludes (D).
