摘要/Abstract

摘要： 用原位乳液聚合法制备了聚甲基丙烯酸甲酯∕膨胀石墨（PMMA∕EG）纳米杂化材料。采用了X射线衍射(XRD)、红外光谱(FT-IR)、透射电子显微镜(TEM)和热分析(TGA-DSC)等仪器对其进行表征，表明所制备的PMMA∕EG纳米杂化材料为椭圆结构，膨胀石墨分散在PMMA基体中，并被PMMA所包裹。用MWW－1P型万能摩擦磨损试验机考察其作为10＃机油添加剂时的抗磨性能，表明所制备的PMMA∕EG作为10＃机油添加剂时对钢－钢摩擦副表现出优异的抗磨作用，其最优添加量为1.5%。EDX能谱分析表明添加剂在磨斑表面形成了富碳表面膜。

Abstract: Polymethyl methacrylate∕expanded graphite (PMMA/EG) hybrid nano-composite was synthesized through in-situ emulsion polymerization of methyl methacrylate in the presence of EG. The as-prepared composite was characterized by XRD, FT-IR, TEM and thermal analysis (TGA-DSC). The test results showed that the prepared PMMA∕EG was elliptical, and EG was dispersed in the polymer matrix and enclosed by PMMA. The effect of using said nano-composite as lube additive on the tribological properties of 10# machine oil was investigated using a MWW-1P friction and wear tester. The evaluation results showed that PMMA∕EG exhibited excellent anti-wear behavior under various loads. The optimal dosage of PMMA∕EG in the 10# machine oil was suggested to be 1.5%. The results of EDX showed that a carbon enriched film was formed on the worn steel surface to protect the steel surface for further wearing.

Key words: polymethyl methacrylate, expanded graphite, additive, antiwear performance
