    • A flame retardant resin composition comprising (A) 100 parts by weight of a synthetic resin, (B) 20 to 150 parts by weight of magnesium hydroxide particles and (C) 20 to 150 parts by weight of aluminum hydroxide particles, wherein the magnesium hydroxide particles and the aluminum hydroxide particles satisfy the following conditions (i) to (v): (i) the average secondary particle diameter measured by a microtrack method is 0.4 to 4 .mu.m; (ii) the specific surface measured by a BET method is 1 to 15 m.sup.2 /g; (iii) the total content of an iron compound and a manganese compound is 200 ppm or less in terms of metals (Fe+Mn); (iv) the ratio of the specific surface measured by the BET method to the specific surface measured by a Blaine method is 1 to 4; and (v) the content of a water-soluble sodium salt is 500 ppm or less in terms of metal sodium. The present invention provide a halogen-free flame retardant resin composition which has excellent thermal stability, acid resistance, water-resistant insulating properties, mechanical strength and surface appearance and is economically advantageous, and a molded article therefrom.
    • 一种阻燃树脂组合物,其包含(A)100重量份的合成树脂,(B)20至150重量份的氢氧化镁颗粒和(C)20至150重量份的氢氧化铝颗粒,其中所述氢氧化镁 颗粒和氢氧化铝颗粒满足以下条件(i)〜(v):(i)通过微轨道法测定的平均二次粒径为0.4〜4μm; (ii)通过BET法测定的比表面积为1〜15m 2 / g; (iii)铁化合物和锰化合物的总含量以金属(Fe + Mn)计为200ppm以下。 (iv)通过BET法测定的比表面积与通过Blaine法测定的比表面积的比例为1〜4; 和(v)以金属钠计,水溶性钠盐的含量为500ppm以下。 本发明提供一种无卤阻燃树脂组合物,其具有优异的热稳定性,耐酸性,耐水绝缘性,机械强度和表面外观,并且在经济上是有利的。
