Provided are an additive for lubricating oil, including a compound represented by the following general formula (1) as an essential component, and a lubricating oil composition blending same: where R 1 , R 3 , R 5 , and R 7 each independently represent an alkyl group having 1 to 20 carbon atoms, R 2 , R 4 , R 6 , and R 8 each independently represent a hydrogen atom or an alkyl group having 1 to 20 carbon atoms, A represents a hydrocarbon group having 2 to 20 carbon atoms, and n represents a number from 1 to 10.
摘要:
Provided are a lubricant composition capable of reducing friction between sliding parts at least one of which contains an aluminum-based material in a lubrication section, and a method for lubricating an aluminum-based member with the composition. The lubricant composition is for use in a lubrication section having sliding parts at least one of which contains an aluminum-based material, and contains a lubricant base oil and at least one of a phosphorus-containing carboxylic compound and a metal salt thereof (component (A)) at 0.001 to 1 mass% of the composition in terms of phosphorus. The composition may suitably be used as lubricant such as drive train lubricant for automatic or manual transmissions, grease, wet brake oil, hydraulic actuation oil, turbine oil, compressor oil, bearing oil, refrigerant oil, and the like used in apparatus having the sliding parts.
摘要:
It is to provide a composition derived from lactic acid bacteria having an anti-allergic effect (an effect of suppressing allergic symptoms such as hay fever) synergistically, and a food product, pet food, etc. containing the composition. It is to prepare a composition having an anti-allergic action, containing Lactobacillus crispatus KT-11 strain, KT-23 strain, or KT-25 strain bacterial cells and viable bacteria, dead bacteria, or a processed product of bacterial cells of other lactic acid bacteria belonging to the genus Lactobacillus, genus Bifidobacterium, genus Leuconostoc, genus Enterococcus, genus Pediococcus, etc. at a biomass-converted ratio of 99:1 to 50:50, preferably 99:1 to 75:25.
摘要:
Disclosed is a method for improving compatibility of a fluorocarbon elastomer seal with a lubricating oil composition containing (a) a major amount of a base oil of lubricating viscosity; and (b) one or more dispersants containing one or more basic nitrogen atoms. The method involves adding to the lubricating oil composition an effective amount of one or more fluorocarbon elastomer compatibility improving agents of the general formula Si—X4 or a hydrolysis product thereof, wherein each X is independently a hydroxyl-containing group, hydrocarbyloxy-containing group, acyloxy-containing group, amino-containing group, monoalkyl amino-containing group or dialkyl amino-containing group.
摘要:
The invention relates to a lubricant composition comprising: (a) an organomolybdenum compound, (b) one or more antiwear and extreme pressure additives chosen from thia(di)azoles, (c) one or more phosphorus-containing and/or phosphorus-sulphur-containing antiwear and extreme pressure additives chosen from phosphites, phosphates, phosphonates, thiophosphates or thiophosphites, said lubricant composition having a weight content of molybdenum between 90 and 350 ppm. Use for the lubrication of gearboxes.
摘要:
Provided is a lubricating oil composition for an internal combustion engine, including as essential components the following component (A), component (B), and component (C), in which a phosphorus content of the composition is 50 ppm by mass to 1,000 ppm by mass: Component (A): a base oil; Component (B): a compound represented by the following general formula (1); and Component (C): a metal-containing antioxidant:
where R 1 to R 8 each independently represent a hydrogen atom or an alkyl group having 1 to 20 carbon atoms, Z represents a hydrocarbon group having 2 to 20 carbon atoms, and n represents a number of 1 to 10.
