硅橡胶阻燃协同作用铁蒙脱土Silicone Rubber Flame Retardant Synergistic Effect Fe-Montmorillonite

摘要:

采用熔融共混法制备了硅橡胶/氢氧化铝/铁蒙脱土阻燃高温硫化硅橡胶。利用垂直燃烧实验、硬度和拉伸实验分别研究了硅橡胶的阻燃性能和机械性能。结果表明氢氧化铝和铁蒙脱土之间存在协同作用,随着铁蒙脱土用量的增加,硅橡胶的垂直燃烧时间减小,阻燃性能明显提高,3.0 wt.%的铁蒙脱土和50.0 wt.%的氢氧化铝并用时,硅橡胶的综合性能较佳。

Silicone rubber/aluminum hydroxide/Fe-montmorillonite retardant high temperature vulcanized silicone rubbers were prepared by melt-mixing process. The flame retardant properties and the mechanical properties of silicone rubber were studied by vertical combustion test, tensile test and hardness test, respectively. The results showed that the synergistic effects between aluminum hy-droxide and Fe-montmorillonite existed in the prepared flame retardant rubber. With the increase of the content of Fe-montmorillonite, the vertical combustion time decreased. When the content of Fe-montmorillonite is 3.0 wt.% and the content of aluminum hydroxide is 50.0 wt.%, the optimum properties of silicone rubber were exhibited.
