摘要:
The present invention is directed to formulated lubricating oils containing ashless detergents comprising the products resulting from the reaction of a sulfonic acid with a thiadiazole or an organic group substituted thiadiazole.
摘要:
A lubricating oil formulation containing a major amount of a base oil of lubricating viscosity and a minor amount of additives comprising a combination of phenyl naphthyl amine, dimercaptothiadiazole or derivative thereof, and triazole or benzotriazole or derivative thereof, exhibiting enhanced resistance to oxidation.
摘要:
Disclosed is a lubricant oil composition which has an excellent preventive property on the abrasion of a metal pulley or a metal belt and an excellent initial shudder preventing property, can exert a shudder preventing property for a prolonged period of time, and is suitable for use in a continuously variable transmission with a sliding-controlled wet clutch and a metal belt. A lubricant oil composition comprising (A) alkylsalicylic acid metal salts composed of 85-100 mol% of a monoalkylsalicylic acid metal salt, 0-15 mol% of a dialkylsalicylic acid metal salt and 40-100 mol% of a 3-alkylsalicylic acid metal salt, each based on the total amount of the composition, and/or a (per)basic salt thereof; (B) a specific nitrogen compound, and (C) a phosphorus-containing anti-abrasion agent in a lubricant base oil.
摘要:
A lubricating composition providing excellent anti-wear protection for corrosion-resistant materials which comprises a major amount of a synthetic ester base oil, and a minor amount of a molybdenum compound and an anti-wear additive selected from the group consisting of 1,3,4-thiadiazole derivatives as an anti-wear additive, the reaction products of 2,5-dimercapto-1,3,4-thiadiazole dimers and poly(ether)glycols, and 2,5-dimercapto-1,3,4-thiadiazole monomer and mixtures thereof. Also described is a method for imparting anti-wear properties to a corrosion resistant material, comprising using the lubricating composition of the invention.
摘要:
A fluid composition is described for extreme pressure applications. The fluid composition includes a base oil, and an additive composition comprising sulfurized fatty oil in an amount sufficient to provide at least 1,000 ppm sulfur to the fluid composition, and dialkyl thiadiazole in an amount sufficient to provide at least 500 ppm sulfur to the fluid composition. Fluids containing these respective amounts of sulfurized fatty oil and dialkyl thiadiazole exhibit failure loads which equal or exceed 794 kg (1750 pounds) at 100°C and 150°C, respectively, as measured according to a Falex EP test of ASTM D-3233.
摘要:
A biodegradable lubricating oil composition especially useful as a gear oil employs a synthetic alcohol ester basestock formed from mono- and dipentaerythritol with certain mono- and dicarboxylic acids or dicarboxylic acid anhydrides and an effective amount of a polyoxyalkylene alcohol demulsifying agent, a combination of alkylated organic acid and ashless succinimide rust inhibitors and an ashless dithiocarbamate antiwear and extreme pressure agent.
