摘要
以双组份加成型液体硅橡胶(LSR)为基胶,白炭黑为补强填料,通过测试分析,对比氢氧化铝、氢氧化镁、碱式硫酸镁晶须、经硬脂酸钠表面处理的碱式硫酸镁晶须4种阻燃剂复合液体硅橡胶的燃烧性能和力学性能。结果表明,经表面处理后的碱式硫酸镁晶须提高了LSR的拉伸强度,并在改善LSR的防火性能方面具有独特的优势。
Taking two-component additional liquid silicone rubber （LSR） as base rubber, silica white carbon black was as reinforcing packing material. Analyzis and comparison of the combustion performance and mechan- ical properties of four flame retardant liquid silicone rubber compound, including aluminum hydroxide, magne- sium hydroxide, magnesium hydroxide sulfate whisker,and the stearic acid sodium surface treatment of magne- sium hydroxide sulfate whisker. The results showed that the stearic acid sodium surface treatment of magnesi- um hydroxide sulfate whisker could improve the tensile strength of LSR, and had a unique advantage in impro- ving the flame resistance of LSR.
