防火硅橡胶材料的研制

采用正交试验设计方法，考察了以有机改性蒙脱土（OMMT）、硼酸锌、硅酸铝纤维和气相法二氧化钛组成的阻燃防火体系对硅橡胶氧指数、最高背面温度和密度等的影响。结果表明：OMMT、硼酸锌、硅酸铝纤维和气相法二氧化钛对硅橡胶具有很好的阻燃防火协同效应，当硅橡胶/OMMT/硼酸锌/硅酸铝纤维/气相法二氧化钛用量比为100/5/30/20/10时，防火硅橡胶具有良好的综合性能。;The effects of the flaMe-retarDant anD fire-resistant aDDitives coMposeD of organo-MontMorillonite(OMMT)，zinc borate(ZnB)，aluMinosilicate fibre(AF) anD fuMeD titaniuM DioxiDe(TiO₂) on the oxygen inDex，MaxiMal back teMperature anD Density of silicone rubber were stuDieD by orthogonal experiMent Design.The results showeD that OMMT，ZnB，AF anD TiO₂ haD gooD synergistic flaMe-retarDant anD fire-resistant effect on silicone rubber，anD the silicone rubber coMpounD haD gooD coMprehensive properties when the blenD ratio of silicone rubber/OMMT/ZnB/AF/TiO₂ was 100/5/30/20/10
