Abstract
Provided are: a flame retardant composition which can impart excellent flame retardancy to a synthetic resin even when added in a small amount; and a flame-retardant synthetic resin composition which contains the flame retardant composition and a resin and exhibits excellent flame retardancy. The flame retardant composition contains components (A) and (B), wherein (A) is a phosphate-based flame retardant, and (B) is a hindered amine compound having a structure represented by Chemical Formula (1) in the structure. In Chemical Formula (1), * represents a bond, and one or more of the structures represented by Chemical Formula (1) optionally exist in the compound.
Claims5
A flame retardant composition comprising components (A) and (B), wherein
- (A) is a phosphate-based flame retardant, and
- (B) is a hindered amine compound having a structure represented by Chemical Formula (1) in the structure:
- where * represents a bond,
- wherein optionally more than one of the structures represented by Chemical Formula (1) exist in the compound,
- wherein the component (A) contains a component (A-1) and a component (A-2), wherein:
- (A-1) is at least one melamine salt selected from the group consisting of melamine orthophosphate, melamine pyrophosphate, and melamine polyphosphate;
- and
- (A-2) is at least one piperazine salt selected from the group consisting of piperazine orthophosphate, piperazine pyrophosphate, and piperazine polyphosphate, and
- wherein a content ratio of the component (A) and the component (B) is in a range of 97:3 to 84:16 in terms of mass ratio.
