%X 试验研究氢氧化镁、氢氧化铝及其复合物对脱酮肟型单组分室温硫化（RTV-1）硅橡胶物理性能和阻燃性能的影响。结果表明，随着氢氧化镁用量的增大，RTV-1硅橡胶的硬度、拉伸强度和氧指数逐渐增大，拉断伸长率逐渐减小，氢氧化镁用量为50份时RTV-1硅橡胶具有阻燃性；氢氧化铝填充RTV-1硅橡胶的硬度、拉伸强度和氧指数均高于相同用量氢氧化镁填充胶，氢氧化铝用量为40份时RTV-1硅橡胶具有阻燃性；氢氧化镁/氢氧化铝并用量为30份时RTV-1硅橡胶具有阻燃性，氢氧化镁/氢氧化铝质量比为1∶4时其阻燃效果最佳。;The influence of magnesium hydroxide［Mg(OH)<sub>2</sub>］，aluminium hydroxide［Al(OH)<sub>3</sub>］ and their  blend on physical properties and flame retardance of monocomponent RTV silicone rubber(RTV-1) was experimentally investigated.The results showed that the hardness，tensile strength and oxygen index(OI) of RTV-1 increased as the addition level of Mg(OH)<sub>2</sub> increased，but the elongation at break decreased，and RTV-1 became flame-retarded when 50 phr Mg(OH)<sub>2</sub> was used；the hardness，tensile strength and OI of RTV-1 filled by Al(OH)<sub>3</sub> were higher than those filled by Mg(OH)<sub>2</sub> in the same content，respectively，and RTV-1 was flame-retarded when 40 phr Al(OH)<sub>3</sub> was added；when the addition level of Mg(OH)<sub>2</sub>/Al(OH)<sub>3</sub> was 30 phr，RTV-1 became flame-retarded，and the optimum mass ratio of Mg(OH)<sub>2</sub>/Al(OH)<sub>3</sub> was 1∶4
