摘要:
The present disclosure relates to conveyor lubricant compositions including an emulsion. The present disclosure also relates to methods of employing such lubricant compositions. In an embodiment, the methods include applying the present lubricant composition to a conveyor with a non-energized nozzle. In an embodiment, the methods include applying the present lubricant composition in a “semi-dry” mode.
摘要:
Multi-functional additives which impart improved antioxidancy to lubricating oil compositions and frictional properties resulting in improved fuel economy in an internal combustion engine are disclosed. More particularly disclosed are lubricating oil compositions for internal combustion engines comprising a) a major amount of an oil of lubricating viscosity; and b) a minor amount of an oil soluble hydroxylated amine salt of a hindered phenolic acid, said salt having the general formula I: wherein A and Q are each independently C2-C6 alkylene group; R is methyl, alkyl or alkenyl group having C2-C24 carbon atoms; Y is hydrogen, C1-C6 alkyl group or A-OH; x is an integer of 1 or 2; and z is an integer of 0 or 1.
摘要:
A lubricating oil composition is provided by mixing a lubricant base oil with components (A) to (C) as follows: (A) a tertiary amine represented by a formula (1) below,
where: R 1 is a hydrocarbon group having 16 to 22 carbon atoms and R 2 and R 3 independently represent a hydrocarbon group having 1 to 2 carbon atoms, R 2 and R 3 being adapted to form a heterocyclic ring with terminal ends thereof being bonded; (B) at least one of acid phosphate and acid phosphite; and (C) at least one of metal sulfonate, metal phenate and metal salicylate.
摘要:
A composition of an oil-soluble ionic detergent that does not contribute metal ions to the composition, and which comprises a quaternary non-metallic pnictogen cation and an organic anion having at least one hydrocarbyl group of sufficient length to impart oil solubility to the detergent, the detergent having a total base number (TBN) to total acid number (TAN) ratio of at least 2:1 imparts ash-free basicity to a lubricant composition.
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:
Compositions comprise first antioxidants and first additives, such as, a surface additives, performance enhancing additives and lubricant protective additives and optionally second additives and/or second antioxidants. The compositions are useful to improve lubricants, lubricant oils and other lubricant materials. The compositions and methods generally provide longer shelf lives, increased oxidative resistance, improved quality and/or enhanced performance to lubricants or lubricant oils.
摘要:
The invention relates to the use of polyamines having at least one terminal secondary or tertiary amine function as a detergent additive for fuels and lubricants. The invention also relates to additive concentrates containing such polyamines, to fuels and lubricants to which the polyamines have been added and to a method for producing them.
摘要:
The present invention provides a lubricating oil additive with excellent cleaning performance which does not include metal components such as calcium or magnesium, and a lubricating oil composition containing the same. The lubricating oil additive according to the present invention is characterized by containing a quaternary ammonium salt having a base number of at least 10 mgKOH/g. Examples of such a quaternary ammonium salt include quaternary ammonium salts obtained by subjecting counter anions in cationic surfactants such as tetraalkylammonium chloride and tetraalkylammonium sulfate to salt-exchange.
