| 摘 要： | 在对蒙脱土表面改性的基础上,采用乳液插层聚合法合成聚苯乙烯/蒙脱土纳米复合材料.FTIR和XRD结果显示,复合材料中蒙脱土面(001面)特征峰消失,聚苯乙烯的大分子链插入到蒙脱土片层间,形成剥离型纳米复合材料.UMT-2MT摩擦试验机测试表明,蒙脱土质量分数为2%时,复合材料摩擦性能最好,载荷越小,摩擦系数降低越明显,1 N载荷下摩擦系数降低了4.62%,2 N载荷下磨损率降低了28%.最后,对复合材料摩擦学性能随蒙脱土含量的变化进行了探讨.

| Abstract: | On the basis of surfacial modification of montmorillonite,the polystyrene/montmorillonite nanocomposite was synthesized by means of emulsion intercalation polymerization.The result of FTIR and XRD showed that the surfacial characteristic peak of the montmorillonite(001) in the composite disappeared and the macromolecular chain of polystyrene was inserted into the laminated layers of montmorillonite to form exfoliative nanocomposite material.The test on wear tester UMT-2MT showed that,when the mass fraction of the montmorillonite was 2%,the tribological performance composite material would be the best,and the less the load was,the more remarkable the decrease of friction factor would be,decrease by 4.62% under 1 N loading and 28.0%-2 N loading.Finally,the dependence of tribological performance of composite material on the content of montmorillonite was discussed,also. |
