摘要/Abstract

摘要： 采用空心玻璃微珠(HGM)、复配型膨胀阻燃剂三聚氰胺聚磷酸盐(MPP)/季戊四醇(PER)、协效阻燃剂氢氧化铝(Al(OH)₃)、缩合型室温硫化液体硅橡胶(107胶)制得了HGM填充型膨胀阻燃硅橡胶。研究了HGM的填充量对膨胀阻燃硅橡胶复合材料各性能的影响。结果表明:随着HGM含量的增加,硅橡胶复合材料的拉伸强度先增加后降低,其断裂伸长率逐渐降低,密度逐渐减小,背面温度先逐渐下降后又小幅度上升。当HGM含量加入至30wt%时,硅橡胶膨胀阻燃复合材料氧指数值达到36,导热系数值为最低值0.15 W·m^-1·K^-1,确定了HGM的最佳填充量为30wt%。

Abstract: With hollow glass microspheres (HGM), composite expansion flame retardant melamine polyphosphate (MPP)/pentaerythritol (PER), synergistic flame retardant aluminum hydroxide Al(OH)₃, condensation type room temperature vulcanization, the liquid silicone rubber (107 glue) was made into a HGM filled type expanded flame retardant silicone rubber. The effect of the loading of HGM on the properties of the expanded flame retardant silicone rubber composite was investigated. The results show that with the increase of HGM content, the tensile strength of silicone rubber composites increases first and then decreases, the elongation at break decreases gradually, and the density decreases, and the backside temperature decreases gradually and then rises slightly. When the HGM content is added to 30wt%, the oxygen index of the silicone rubber expanded flame retardant composite reaches 36, and the thermal conductivity value achieves the lowest value of 0.15 W·m^-1·K^-1, which demonstrates that the optimal filling amount of HGM is 30wt%.
