摘　　要：以热弧等离子体法制备高纯度纳米硅,通过机械共混法制备炭黑/氟橡胶(FKM-C)和纳米硅/氟橡胶(FKMSi)复合材料,与不加填料的纯氟橡胶(P-FKM)复合材料相比,研究填料对氟橡胶性能的影响。结果表明:FKM-Si复合材料的脆性温度低于P-FKM复合材料;FKM-Si复合材料的硬度、拉伸强度和拉断伸长率均高于FKM-C复合材料,分别达到70度、12.16 MPa和289%;FKM-Si复合材料的截面无缺陷,说明纳米硅与氟橡胶的相容性好;FKM-Si复合材料的热稳定性比FKM-C复合材料好。High-purity nano silicon was synthesized by the hot-arc plasma method,and carbon black/fluorine rubber(FKM-C)and nano silicon/fluorine rubber(FKM-Si)composites were prepared by mechanical blending method.Compared with pure fluorine rubber(P-FKM)composite without fillers,the effect of fillers on the properties of fluorine rubber was studied.The results showed that the brittleness temperature of FKM-Si composite was lower than that of P-FKM composite.The hardness,tensile strength and elongation at break of FKM-Si composite were higher than those of FKM-C composite,reaching 70 degree,12.16 MPa and 289%,respectively.The cross-section of FKM-Si composite had no defects,indicating that nano silicon had good compatibility with FKM.The thermal stability of FKM-Si composite was better than that of FKM-C composite.
