Abstract

A flame-retardant synthetic-resin composition which comprises 20-50 parts by mass of component (A) which is at least one melamine salt selected from the group consisting of melamine orthophosphate, melamine pyrophosphate, and melamine polyphosphate, 50-80 parts by mass of component (B) which is at least one piperazine salt selected from the group consisting of piperazine orthophosphate, piperazinepyrophosphate, and piperazine polyphosphate (the sum of component (A) and component (B) is 100 parts by mass), and 1-50 parts by mass of component (C) which is a compound represented by formula (1).(R1 represents a residue of an aliphatic monocarboxylic acid or a residue of an aromatic monocarboxylic acid.)

Description

technical field [0001] The present invention relates to a flame retardant composition and a flame retardant synthetic resin composition containing the flame retardant composition. Background technique [0002] Conventionally, synthetic resins have been widely used in construction materials, automobile parts, packaging materials, agricultural materials, casing materials for home appliances, toys, etc. due to their excellent chemical and mechanical properties. However, most synthetic resins are flammable, and flame retardancy is indispensable depending on the application. As a flame retardant method, halogen-based flame retardants, inorganic phosphorus-based flame retardants represented by polyphosphate-based flame retardants such as red phosphorus or ammonium polyphosphate (also called ammonium polyphosphate) are used alone or in combination, Organophosphorus flame retardants represented by triaryl phosphate ester compounds, metal hydroxides, antimony oxide and melamine comp...
