摘要/Abstract

摘要： 采用经质子化处理后的十八烷基胺改性黏土制备丁腈橡胶/黏土纳米复合材料(NBRCNs)。旨在获得具有更大晶层间距结构的有机黏土(OC)(XRD测试),削弱黏土片层之间的界面作用力,将黏土片层以纳米尺寸均匀分散在NBR中(SEM、TEM表征),最终获得具有优异力学性能的 NBRCNs。实验结果表明,当有机黏土含量为10phr时,采用经质子化处理后的十八烷基胺改性黏土制备NBRCNs的拉伸强度、撕裂强度、100%/300%定伸应力及硬度,与采用常规的长链脂肪族季铵盐改性有机黏土制备的NBR/C₁₆-OC纳米复合材料和NBR/S₁₈-OC纳米复合材料相比,分别提高了61.04%、51.79%、30%/26.21%、7.27%和80.28%、49.57%、31.09%/34.72%、11.32%。

Abstract: NBRCNs was prepared by mixing nitrile butadiene rubber with protonated octadecyl amine modified clay to further expand the layer space and weaken the layer-layer interaction.Attributed to greatly improved dispersion uniformity of silicate layers,the prepared nanocomposites by protonated octadecyl amine modified clay demonstrated superior properties to those of nanocomposites prepared by the traditional long chain aliphatic quaternary amine modified clay.Compared with NBR/C₁₆-OC and NBR/S₁₈-OC nanocomposites,NBRCNs with 10phr loading of protonated octadecyl amine modified clay exhibited about 61.04% and 80.28% increase in tensile strength,51.79% and 49.57% increase in tear strength,30%/26.21% and 31.09%/34.72% increase in 100%/300% stress,and 7.27% and 11.32% increase in Shore A hardness.
