The present invention relates to a treatment to be used as an additive to a stock lubricant. The present invention may comprise an amount of a base fluid or other fluid, such as polybutylene, naphthenic oil, or a group III base fluid and a bismuth in a non-active sulfur. The present invention formula may further comprise one or more of a defoamer, a friction modifier, a detergent, a dispersant, and a polyol ester. Bismuth may be a particularly good sacrificial material for use as a lubricant additive because it is a heavy weight inorganic material that becomes soft at high temperatures. The preferred embodiment may utilize approximately 60% of the base fluid and approximately 30% of the bismuth in a non-active sulfur (approximately 15%-18% by weight bismuth) by volume. The treatment can be useful as a additive to a motor oil, a hydraulic lubricant, a gear lubricant, a diesel oil lubricant, or a compressor lubricant.
本发明涉及一种用作原油润滑油添加剂的处理方法。本发明可包含一定量的基础油或其他流体,例如聚丁烯、环烷油或 III 族基础油以及非活性硫中的铋。本发明配方可进一步包含消泡剂、摩擦改进剂、洗涤剂、分散剂和多元醇酯中的一种或多种。铋可能是一种特别适合用作润滑油添加剂的牺牲材料,因为它是一种重量级无机材料,在高温下会变软。优选的实施方案可以使用约 60% 的基础油和约 30% 的非活性硫中的铋(铋的重量百分比约为 15%-18%)(按体积计算)。该处理剂可用作机油、液压润滑剂、齿轮润滑剂、柴油润滑剂或压缩机润滑剂的添加剂。
