| 摘 要： | 采用自由基乳液聚合方法合成了纳米石墨／聚丙烯酸乙酯复合乳液，并用四球摩擦磨损试验机对其润滑性能进行了评估。结果表明，一定浓度的纳米石墨／聚丙烯酸乙酯复合乳液可有效提高水基液的承载能力，降低磨损量。采用IRMM对摩擦磨损试验后的钢球磨斑表面进行分析，结果表明：磨痕变浅，磨斑减小，有效降低了磨损。

| Abstract: | Nonographite/ Poly(ethyl acrylate) Compound Latex were synthesized through in-situ free radical polymerization of ethyl acrylamide in the presence of the nanographite.The effect of the synthetic product as an additive on the load-carrying capacity and anti-wear behavior of a water-based fluid was investigated on a four-ball machine.The worn surfaces of the steel balls were observed with IRMM.The results show that the polymer at a certain concentration in the base stock effectively raised the load-carrying capacity (p_B value) and anti-wear ability. |
