摘　　要：采用共沉淀法分别合成对苯乙烯磺酸钠和十二烷基苯磺酸钠(SDBS)改性水滑石(LDH),再制备改性LDH/SBR复合材料,并对复合材料的性能进行研究。结果表明:改性LDH能够提高SBR胶料的硫化速度,而不影响加工安全性;改性LDH能够改善SBR硫化胶的热稳定性、阻燃性能和物理性能;改性剂品种对复合材料热稳定性影响不大,SDBS-LDH/SBR复合材料的阻燃性能较好。Sodium styrene sulfonate（SSS） or sodium dodecylbenzenesulfonate（SDBS） modified layered double hydroxide（LDH） was obtained by coprecipitation method,the modified LDH/SBR composite was prepared,and properties of the composite were investigated.The results showed that by adding modified LDH,the curing rate of SBR compound increased,and the processing safety changed little.The thermal stability,flame retardant property and physical properties of the SBR vulcanizate were improved.It was found that the type of modifier had little effect on the thermal stability of composite,and the SDBS-LDH/SBR composite possessed better flame retardant property.
