| 摘 要： | 天然硅灰石矿物具有特殊的针状结构，白色，无毒，是橡胶、塑料的理想填料。添加硅灰石填料，可降低橡胶制品的生产成本，提高橡胶的力学性能，赋以橡胶自身所没有的特殊功能。其作用大小取决于硅灰石／橡胶界面的结合状态。硅灰石系亲水性矿物，与橡胶相容性差。界面能否形成良好的粘结，硅灰石矿物表面性能是关键。经超细粉碎、表面改性可以提高硅灰石表面活性，增强与橡胶的粘结强度。但是，当硅灰石经超细粉碎，粒度为微米级或纳米级，粉体容重为０－１５ｇｃｍ３，以表面化学改性方法加入偶联剂，经高温高速搅拌，不但破坏硅灰石的长…

| Abstract: | The wollastonite pulverized activated by supersonic speed airflow substitutes for white carbon as a strengthening agent to rubber.The microstructures on surface of such developed wollastonite powder and microstructures on interface of rubber/wollastonite composite material have been researched by scanning electron microscope and infrared absorption spectroscopy.The mechanism of mechanicaochemical activation on wollastonite and crosslinking mechanism on inerface of rubber/wollastonite composite material have been revealed by the results of research. |
