摘要

用机械共混法制备了氮化硼/多壁碳纳米管/溴化丁基橡胶复合材料,测试了复合材料的力学和导热性能,观察了填料在复合材料中的分散和分布情况,并对结果进行了理论分析。结果表明:填充氮化硼和多壁碳纳米管都可以有效提高溴化丁基橡胶的力学性能和导热性能。对于复合材料力学性能的提高,多壁碳纳米管起到了主要作用。对于复合材料导热性能的提高,氮化硼更容易形成导热网链,而且氮化硼和多壁碳纳米管存在协同作用。扫描电子显微镜结果表明,氮化硼和多壁碳纳米管在溴化丁基橡胶中形成了有效的填料网络。
        Boron nitride/multi-walled carbon nanotube/brominated butyl rubber(BN/MWCNT/BIIR)composite was prepared by mechanical blending method.The mechanical property and thermal conductivity of composites were tested.The dispersion and distribution of BN and MWCNT in rubber matrix were observed.The corresponding theoretical analysis was carried out.Experimental results showed that the addition of BN and MWCNT can improve the mechanical property and thermal conductivity of BIIR efficiently.MWCNT played the main function in improving mechanical properties of BIIR composite.However,BN was easier to form a thermal conductivity net chain than MWCNT.BN and MWCNT had a synergistic effect on the improvement of thermal conductivity.SEM images showed that BN and MWCNT formed an effective filler network in BIIR matrix.
