摘　　要：采用溶液乳化法制备出了溴化丁基胶乳,并通过乳液共混法制备纳米SiO2/溴化丁基橡胶(BIIR)复合材料。结果表明,改性的纳米SiO2可以很好的分散在溴化丁基橡胶胶乳(BIIRL)中;通过涂布成型硫化后,纳米SiO2/BIIR复合材料具有良好的物理性能,其断裂伸长率、拉伸强度和拉伸断裂应力都得到了较大提高;在SiO2用量很少的情况下,气密性得到了显著的提高。Emulsion were prepared by solution of the brominated butyl rubber latex,and preparation of emulsion blending nano-SiO2/brominated butyl rubber（BIIR） composite materials.The results showed that the modified nano-SiO2can be well disperseding brominated butyl rubber latex（BIIRL）;After vulcanization molding by coating,nano-SiO2/BIIR composite material had excellent physical properties,its elongation at break,tensile strength and tensile fracture stress had improved greatly;In a small amount of SiO2 special circumstances,the air tightness had significantly improved.
