活性硅铝炭黑的性能及应用

将硅铝炭黑（ＳＡＣ）进行活化改性制成活性硅铝炭黑（ＡＳＡＣ），并对ＳＡＣ和ＡＳＡＣ填充ＮＲ和ＳＢＲ胶料的硫化特性、物理性能及流变性能进行研究。结果表明，ＡＳＡＣ能明显改善ＳＡＣ的延迟硫化效应，提高填充胶料的力学性能；ＡＳＡＣ在ＮＲ中的填充补强效果接近半补强炭黑，在ＳＢＲ中的填充补强效果略优于优质陶土；ＡＳＡＣ填充ＮＲ胶料的流动性好，挤出胀大效应与填充半补强炭黑胶料相近

Properties and Application of Activated Silica-alumina Carbon Black

The activated silica alumina carbon black (ASAC) was prepared by modifying the silica alumina carbon black (SAC).The curing behaviour,physical properties and rheological properties of NR and SBR compounds respectively filled with SAC and ASAC were investigated.The results showed that the delayed vulcanization and the mechanical properties improved when ASAC was used in rubber compound instead of SAC;the reinforcing effect of ASAC was similar to that of semi reinforcing carbon black in NR compound,and somewhat better than that of quality clay in SBR compound;ASAC filled NR compound possessed good flow property and similar die swell to that of semi reinforcing carbon black filled compound.
