Abstract

Disclosed is a flame retardant composition which comprises: a flame retardant composition comprising 1 to 99 parts by mass of a salt of piperazine with an inorganic phosphorus compound selected from piperazine phosphate, piperazine pyrophosphate, piperazine polyphosphate and a mixture of two or more of these piperazine salts (component (A)), and 99 to 1 part by mass of a salt of melamine with an inorganic phosphorus compound selected from melamine phosphate, melamine pyrophosphate, melamine polyphosphate and a mixture of two or more of these melamine salts (component (B)) (provided that the total amount of the components (A) and (B) is 100 parts by mass); 0.01 to 10 parts by mass of a silicone oil (component (C)); and 0.01 to 20 parts by mass of a monoester compound (component (D)) produced by reacting a monoamide compound of a higher aliphatic carboxylic acid and / or a higher aliphatic carboxylic acid with a univalent to trivalent alcoholic compound.

Description

technical field [0001] The present invention relates to the (poly / pyro) phosphate compound of piperazine and melamine, organosilicon oil and the monoamide compound of higher aliphatic carboxylic acid and / or make higher aliphatic carboxylic acid and monohydric-trihydric alcohol react and obtain A flame retardant composition in which a monoester compound is an essential component. More specifically, the present invention relates to suppressing processing time by blending a silicone oil and a specific amide compound and / or a specific ester compound with a phosphoric acid ester compound having a specific structure. Flame retardant composition having excellent processability stability and flame retardancy of produced char (also referred to as die char or die deposit) and flame retardant synthetic resin using the flame retardant composition combination. Background technique [0002] Synthetic resins have been widely used in construction materials, automobile parts, packaging mate...
