研究类绢云母/丁苯橡胶(SBR)复合材料的硫化特性及物理性能。结果表明:添加类绢云母后的SBR胶料物理性能提高;类绢云母对SBR的补强效果优于碳酸钙、高岭土和沉淀硫酸钡等通用无机填料;偶联剂改性有利于提高类绢云母/SBR复合材料的性能,偶联剂Si69的改性效果较突出;当偶联剂Si69用量为类绢云母用量的10%时,胶料的拉伸强度和耐磨性能较好。
Study on vulcanization and physical properties of sericite / styrene butadiene rubber (SBR) composites. The results showed that the physical properties of SBR were improved after the sericite was added. The reinforcing effect of sericite on SBR was better than that of calcium carbonate, kaolin and precipitated barium sulfate. Mica / SBR composite performance, coupling agent Si69 more prominent effect; when the amount of coupling agent Si69 sericite 10%, the rubber compound tensile strength and wear resistance is better.
