Provided is a polyphenylene ether flame-retardant resin composition having excellent flame retardance and long-term flame retardance. The flame-retardant resin composition contains: (A) a resin including (A-1) a polyphenylene ether; and (B) a flame retardant. The (A-1) component has a content of 50 mass% or more when the flame-retardant resin composition minus ash content, corresponding to a residue obtained upon burning of the flame-retardant resin composition, is taken to be 100 mass%. A shaped article of 12.6 cm in length, 1.3 cm in width, and 1.6 mm in thickness formed from the flame-retardant resin composition exhibits a rate of change of chloroform-insoluble content of 15 mass% or less through aging in which the shaped article is left for 1,000 hours at 150°C in an atmospheric air.
本文提供了一种具有优异阻燃性和长期阻燃性的聚苯醚阻燃树脂组合物。该阻燃树脂组合物包含:(A) 包括(A-1)聚苯醚的树脂;以及 (B) 阻燃剂。当阻燃树脂组合物的灰分含量(相当于阻燃树脂组合物燃烧后的残留物)为 100 质量%时,(A-1) 成分的含量为 50 质量%或以上。由阻燃性树脂组合物制成的长 12.6 厘米、宽 1.3 厘米、厚 1.6 毫米的成型品,在大气空气中于 150°C 下放置 1,000 小时的老化过程中,氯仿不溶物含量的变化率为 15 质量%或更低。
