A flame-retardant polyethylene terephthalate-series resin composition comprises, relative to 100 parts by weight of (A) a polyethylene terephthalate-series resin, (B) 5 to 60 parts by weight of a bromine-containing flame retardant in which 5% by weight reduction from the initial weight thereof is given at a temperature of not less than 360°C under heating the flame retardant at a heating rate of 10°C/min. in a nitrogen stream; (C) 0.01 to 20 parts by weight of a crystallization accelerator; (D) 0.01 to 20 parts by weight of a colorant; and (E) 0.01 to 5 parts by weight of an antioxidant. The resin composition is excellent in resistance to heat/humidity, and has a color difference represented by a ΔE value of not more than 15 under heating the composition at 210°C for 24 hours. The resin composition may comprise an antimony-containing flame-retardant synergist and/or an inorganic filler.
The resin composition ensures effective inhibition of discoloration, and strikes a balance between mechanical properties and heat fading resistance.
一种阻燃聚对苯二甲酸乙二醇酯系列树脂组合物,相对于 100 份重量的(A)聚对苯二甲酸乙二醇酯系列树脂,(B)5 至 60 份重量的含溴阻燃剂,其中在不低于 360℃的温度下,在氮气流中以 10℃/分钟的升温速度加热阻燃剂,阻燃剂的重量比初始重量减少 5%;(C)0.01 至 20 份重量的结晶促进剂;(D)0.01 至 20 份重量的着色剂;以及(E)0.01 至 5 份重量的着色剂。(C) 0.01 至 20 份(按重量计)结晶促进剂; (D) 0.01 至 20 份(按重量计)着色剂;以及 (E) 0.01 至 5 份(按重量计)抗氧化剂。该树脂组合物具有优异的耐热/耐湿性,在 210°C 下加热 24 小时后,其色差以 ΔE 值表示不超过 15。树脂组合物可包括含锑阻燃增效剂和/或无机填料。
该树脂组合物可确保有效抑制褪色,并在机械性能和耐热褪色性之间取得平衡。
