摘　　要：本文主要研究了重晶石粉的干法表面改性及改性重晶石粉在丁苯橡胶中的应用。并通过测定改性重晶石粉的活化指数 ,确定了改性剂的种类、用量和最佳改性温度。选定改性效果好的重晶石粉充填于丁苯橡胶中 ,通过测定制品拉伸率与扯断强度 。The paper has studied dry surface modification of barite powders, and determined the sorts quantities of modifying agents and the best modification temperature by its activatide parameters. According to the modificaton effects, the best modificated barite powders are chosen to fill into SBR, and the variation of the mechanical properties of the non-filled and filled products are tested.
