Abstract:
1. A flame-retardant resin composition comprising a resin component and a flame retardant; wherein the resin component comprises a polyalkylene arylate-series resin and a styrenic resin, and the flame retardant comprises a phosphazene compound and a phenolic resin, in which the phosphazene compound comprises at least one member selected from the group consisting of (1) a cyclic phenoxyphosphazene compound, (2) a linear phenoxyphosphazene compound, and (3) a crosslinked phenoxyphosphazene compound, as described below respectively: (1) the cyclic phenoxyphosphazene compound (2) the linear phenoxyphosphazene compound (3) the crosslinked phenoxyphosphazene compound which is a compound formed by crosslinking at least one phenoxyphosphazene compound selected from the group consisting of the cyclic phenoxyphosphazene compound (1) and the linear phenoxyphosphazene compound (2) with at least one crosslinking group selected from the group consisting of o-phenylene group, m-phenylene group, p-phenylene group, and a bisphenylene group represented by the formula (3): the phenolic resin comprises at least one member selected from the group consisting of an aminotriazine-modified phenol-novolak resin, a phenolic resin in which part or all of phenolic hydroxyl groups is changed into a glycidyl ether group, a high-ortho phenol-novolak resin, a monomerless novolak resin, and a dimerless novolak resin, and wherein the amount of the styrenic resin is 1 to 50 parts by weight relative to 100 parts by weight of the polyalkylene arylate-series resin, and the amount of the phosphazene compound is 50 to 750 parts by weight relative to 100 parts by weight of the styrenic resin, and the amount of the phenolic resin is 20 to 1000 parts by weight relative to 100 parts by weight of the styrenic resin, and wherein the resin composition further comprises at least one member selected from the group consisting of a nitrogen-containing compound, a phosphorus-series compound, a sulfur-containing compound, a silicon-containing compound, and an inorganic metal compound.
