介绍白炭黑改性及其在橡胶中的应用研究进展。通过白炭黑表面接枝改性和偶联剂改性以及白炭黑与其它填料插层复配，可增强白炭黑与橡胶间的相互作用，改进白炭黑的补强效果。白炭黑用于天然橡胶、顺丁橡胶、丁苯橡胶、三元乙丙橡胶等中，胶料网络结构增强，物理性能和抗湿滑性能改善，滚动阻力降低。未来白炭黑研究应集中在白炭黑的界面属性方面，以进一步发挥白炭黑作为补强填料的优势。%The advances in modiifcation of silica and applications of modiifed silica in rubber compounds are reviewed. The interaction between silica and rubber is enhanced by surface modification of silica through grafting, silane coupling or intercalation compounding with other ifllers, which improves the reinforcing effect of silica. Silica can be used for the reinforcement of NR, BR, SBR and EPDM. The physical properties and wet skid resistance are improved with silica reinforcement, and the rolling resistance is reduced. Future studies should focus on the silica interface properties in order to further develop the advantages of silica as reinforcing ifller.
