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。
Nanographite/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 (pB value) and anti-wear ability.
