| Abstract: | The modified graphite ore(G)was prepared with silane Si-69 by wet ball milling in different solutions.The microstructure and surface chemical properties of modified graphite ore and the mechanical properties and thermal stability of styrene butadiene rubber(SBR)composites filled with graphite ore were investigated.The results indicate that the microstructure and surface chemical properties of the modified graphite ore obtained using different ball milling solutions were also different.The GI(isopropanol used as ball milling solution)particle size is smaller and much more lamellae modified graphite can be obtained.The silane Si-69 mainly forms Si-O-C functional groups on the surface of GI and the binding of the modified fillers to the rubber matrix is high,which is benefit to the mechanical properties and thermal stability of composite materials. |
