反机场跑道润滑剂配方研究

Study on the Formulation of Lubricant for Anti-runway

根据混凝土/橡胶摩擦副的表面物理化学结构,研制了新的硅油脂配方,分析了添加剂品种、添加剂含量、持续时间等因素对润滑剂摩擦系数的影响,并将它与几种常用润滑剂进行润滑摩擦系数的实验对比,从分子结构的角度对试验结果进行理论分析。结果表明:对混凝土/橡胶轮胎摩擦副的润滑,自制硅油脂可以使其摩擦系数保持在飞机制动困难状态(μ≤0.45),并且可以维持较长时间(t>72h)。

In this article,a new grease of silicone fluid under atmospheric pressure,which is compounded by stearic acid,methylic silicone fluid,some other additives,etc is proposed.Its friction coefficient with those of some other lubricants is compared.Result show that the new grease can make the friction factor of concrete-rubber lower than 0.45 and maintain long time(t>72h),the result is also theoretically analyzed from molecule structure.
