中文摘要:
      采用铝酸酯偶联剂对氢氧化镁进行表面改性，并将改性氢氧化镁分别与氢氧化铝、三氧化二锑以及磷系、氮系、硅系阻燃剂等进行复配，研究无卤复配阻燃剂对天然橡胶（NR）胶料硫化特性、物理性能和燃烧性能的影响及其在NR硫化胶中的分散性。结果表明：与填充未改性氢氧化镁的NR胶料相比，填充改性氢氧化镁以及复配阻燃剂的NR胶料t10均明显延长，交联程度增大，硫化胶的拉伸强度和拉断伸长率提高；填充改性氢氧化镁/聚磷酸铵/三聚氰胺复配阻燃剂的NR硫化胶阻燃性能最好，填充氢氧化镁和改性氢氧化镁的NR硫化胶阻燃性能较差；改性氢氧化镁/聚磷酸铵/三聚氰胺复配阻燃剂在NR硫化胶中分散均匀。
英文摘要:
      Abstract：In this study，magnesium hydroxide was surface modified by using aluminate coupling agent，and then halogen-free composite flame retardant was formulated by using the modified magnesium hydroxide，aluminum hydroxide，antimony trioxide，and phosphorus-based，nitrogen-based and siliconbased flame retardants. The dispersion of the halogen-free composite flame retardant in NR was studied，and the effects of the composite flame retardant on the vulcanization characteristics，physical properties and combustion properties of NR compound were investigated. The results showed that，compared with the NR compound filled with unmodified magnesium hydroxide，t10 of the NR compound filled with modified magnesium hydroxide or the composite flame retardant was significantly longer，the crosslinking degree increased，and the tensile strength and elongation at break of the ulcanizates were improved. The flame retardant property of the NR vulcanizates filled with modified magnesium hydroxide/ammonium polyphosphate/melamine composite flame retardant was the best，and that of the NR vulcanizates filled with magnesium hydroxide and modified magnesium hydroxide was poor. It was found that the dispersion of modified magnesium hydroxide/ammonium polyphosphate/melamine composite flame retardant in NR compound was quite uniform.
