An extreme pressure agent and a friction coefficient modifier which comprises a compound having, in a molecule, a group represented by general formula (I):
wherein R1, R2, and R3 each represents hydrogen atom or methyl group, and at least one of R2 and R3 represents hydrogen atom; a fluid resistant to seizure under load and a wear resistant fluid which each comprises the above additive or the above modifier; and a flame resistant fluid which comprises a thermally polymerizable substance, preferably the above compound.
The extreme pressure agent and the friction coefficient modifier have excellent properties and are advantageously used for lubricating oil, metal working oil, and hydraulic oil. The flame resistant fluid suppresses vaporization of flammable substances by thermal polymerization to prevent fire when the fluid is exposed to a high temperature and is advantageously used as lubricating oil, metal working oil, hydraulic oil, heat treatment oil, and grease.
一种极压剂和一种摩擦系数调节剂,它包括在分子中具有通式(I)所代表基团的化合物:
其中 R1、R2 和 R3 分别代表
氢原子或
甲基,R2 和 R3 中至少有一个代表
氢原子;一种抗负载骤停流体和一种抗磨损流体,它们分别包含上述
添加剂或上述改性剂;以及一种抗燃流体,它包含一种可热聚合的物质,最好是上述化合物。
极压剂和摩擦系数改良剂具有优异的性能,可用于润滑油、
金属加工油和液压油。阻燃流体通过热聚合作用抑制易燃物质的蒸发,防止流体暴露在高温下起火,可用作润滑油、
金属加工油、液压油、热处理油和润滑脂。
