ABS/硅橡胶共混物的阻燃性能研究

The Flame Retardant Property of ABS/Silicone Rubber Blends

研究了十溴联苯醚/三氧化二锑(DBDPO/Sb2O3)、有机硅橡胶/含氟聚合物、有机硅橡胶/硬脂酸镁、二盐基亚磷酸铅、滑石粉对ABS燃烧性能的影响.研究结果表明:DBDPO/Sb2O3阻燃体系配合含氟聚合物对ABS/硅橡胶共混物的阻燃是有效的.当硅橡胶2PHR、含氟聚合物1PHR、添加剂DBDPO/Sb2O320PHR时,ABS的氧指数达27;二盐基亚磷酸铅对硅橡胶/硬脂酸镁阻燃ABS有较强的助阻燃作用.

In this paper, the effects of DBDPO/Sb_2O_3, silicone rubber/fluorine-containing polymer, silicone rubber/magnesium stearate, dibasic lead phosphite and talcum powder on the flame retardance of ABS plastics were studied. The results demonstrated that DBDPO/Sb_2O_3 fire resistant system combined with fluorine-containing polymer was effective in improving the flame retardant property of ABS/silicone rubber blends. By adding silicone rubber 2 PHR, fluorine-containing polymer 1 PHR, additive, DBDPO/Sb_2O_3, 20 PHR, the OI value of ABS could reach 27. Dibasic lead phosphite was good flame retardant aid to ABS fire retarded with silicone rubber/magnesium stearate.
