用离子液体( IL)氯化-1-烯丙基-3-甲基咪唑改性氧化石墨烯( IL-GO)/IL改性白炭黑( IL-白炭黑)填充天然橡胶( NR),研究了IL-GO在硫化胶中的分散状况,考察了IL-GO用量对NR混炼胶的结合胶、硫化特性及硫化胶的物理机械性能、导热性能的影响。结果表明, IL可以明显改善GO在NR中的分散性,同时可促进NR混炼胶的硫化；当IL-GO用量为1份时,NR硫化胶的物理机械性能和导热性能达到最佳,拉伸强度、撕裂强度和导热系数均达到最大值,分别为27．26 MPa、74．30 kN/m和0．213 W/( m·K)；随着IL-GO用量的增加,NR硫化胶的储能模量上升,玻璃化转变温度下降。%Natural rubber ( NR ) was filled with silica and graphene oxide ( GO) modified with ionic liquid 1-allyl-3-methyl-imidazolium chloride( IL) re-spectively, the dispersion of GO modified with IL ( IL-GO) in NR vulcanizates was studied, and the effects of IL-GO on the curing characteristics, bound rubber of NR compounds and the mechanical proper-ties, thermal conductivity of NR vulcanizates were investigated. The results showed that IL could signi-ficantly improve the dispersion of GO and promote cure of NR compounds. When the amount of IL-GO was 1 phr, the mechanical properties and thermal con-ductivity of NR vulcanizates achieved the best, the tensile strength, tear strength and thermal conductivity were improved to the maximum,27. 26 MPa,74. 30 kN/m and 0. 213 W/(m·K). With increasing amount of IL-GO, the storage modulus of vulcanizates increased, and the glass transition temperature decreased.
