LUBRICANT OR GREASE WITH WEAR RESISTANCE, ANTI-FRICTION AND DISPERSION STABILITY, AND METHOD FOR PREPARING THE SAME

To provide a lubricant or grease with wear resistance, anti-friction, and dispersion stability.SOLUTION: The lubricant or grease comprises: a main component of the lubricant or grease; and a sulfonated graphene grafted with a long carbon chain. A method for preparing the same comprises mixing the main component of the lubricant or grease with the sulfonated graphene grafted with a long carbon chain, and stirring and dispersing the mixture.EFFECT: The lubricant or grease according to the present invention has significantly improved long-term dispersion stability and significantly improved dispersion stability in a complex environment by adding the sulfonated graphene grafted with a long carbon chain to the main component, at the same time the lubricant or grease has a significantly improved coefficient of friction, and significantly improved wear resistance and anti-friction properties, and the lubricant or grease has a reduced wear scar diameter and reduces copper and iron wear.SELECTED DRAWING: Figure 2 【課題】耐摩耗、減摩および分散安定の潤滑油またはグリースを提供する。【解決手段】潤滑油またはグリースの主成分と、長い炭素鎖をグラフトしたスルホン化グラフェンとを含み、その調製方法は、潤滑油またはグリースの主成分と、長い炭素鎖をグラフトしたスルホン化グラフェンとを混合し、攪拌し、分散させることで得られる。【効果】本発明に係る潤滑油またはグリースは、主成分に長い炭素鎖をグラフトしたスルホン化グラフェンを添加することにより、長期にわたる分散安定性と複雑な環境における分散安定性を顕著に向上させると同時に、摩擦係数を顕著に良化させ、潤滑油またはグリースの耐摩耗および減摩性を顕著に向上させ、摩耗痕径を減少し、銅および鉄の摩耗を軽減した。【選択図】図２
