摘　　要：分析短纤维/橡胶复合材料的混炼机理,针对短纤维胶料混炼特点设计新型变间隙六棱同步转子。转子棱峰与密炼室内壁间隙影响短纤维在胶料中的混合和分散以及混炼胶中短纤维的长度。新型六棱同步转子采用变间隙设计,大间隙有助于短纤维的混合,小间隙有助于短纤维的分散。采用新型六棱同步转子可改善短纤维/橡胶复合材料的混炼质量和性能,并能够提高生产效率。The mixing mechanism of short fiber/rubber composite was analyzed,and the new 6-wing synchronous rotor with variable clearance was designed considering the mixing characteristics of short fiber compound.The clearance gap between the rotor edge peak and mixer room influenced mixing,dispersion and length of the short fibers in compound.The new rotor was designed with variable clearance gap,in which the large clearance gap helped the mixing,and the small clearance gap helped to improve the dispersion of short fiber.The mixing quality and performance of short fiber/rubber composite were improved by using the new rotor,and the production efficiency increased.
