Abstract

Provided are: a phosphate amine salt composition which can be used as a flame retardant that is capable of imparting excellent flame retardancy and weather resistance to synthetic resins without a risk of corroding a processing machine; a phosphate amine salt flame retardant composition; a flame-retardant synthetic resin composition containing the same; and a molded article thereof. The phosphate amine salt composition contains at least one phosphate amine salt, and the ammonium cation content therein is 100 to 2,000 ppm by mass. An amine in the phosphate amine salt composition is preferably melamine or piperazine.

Claims (6)

1. A flame-retardant synthetic resin composition, comprising a phosphate amine salt composition, comprising at least one phosphate amine salt incorporated into a polyolefin-based resin, wherein the ammonium cation content of the phosphate amine salt composition is 100 to 2000 ppm by mass, and wherein an amine in the phosphate amine salt composition is melamine or piperazine.

2. The flame-retardant synthetic resin composition according to claim 1 , wherein the phosphate amine salt composition comprises a mixture of

(A) a phosphate amine salt composition, wherein an amine in the phosphate amine salt composition (A) is melamine and

(B) a phosphate amine salt composition, wherein an amine in the phosphate amine salt composition (B) is piperazine.

3. The flame-retardant synthetic resin composition according to claim 2 , wherein the content ratio of the phosphate amine salt composition (A) and the phosphate amine salt composition (B), (A)/(B), is in a range of 20/80 to 80/20 in terms of mass ratio.

4. A molded article obtained from the flame-retardant synthetic resin composition according to claim 1 .
