摘要:
The present invention is a lubricant composition, composed of a lubricant base oil containing: a (poly)glyceryl ether represented by the following general formula (1) (wherein R1 represents a hydrocarbon group and n represents a numeral being 1 or more.), as a (A) component; and an alkaline-earth metal salt of an organic acid as a (B) component. Furthermore, it is preferable to contain an antioxidant as a (C) component. As an alkaline-earth metal salt of an organic acid, sulfonate, phenate, or salicylate are preferable, and neutral, basic or overbased calcium salicylate or calcium sulfonate are particularly preferable.
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.
摘要:
The invention provides a surface-treating agent for a metal can, which diminishes friction on an outside surface of the can without giving a bad influence on attachability of paint, lacquer and the like and shows high safety to the human body. Furthermore, the invention provides a method for treating a metal can surface with said surface-treating agent. The surface-treating agent for a metal can is characterized by containing an ester compound between a polyglycerol and fatty acid(s) as an essential component. To diminish a friction coefficient of the metal can surface, the surface-treating agent is brought into contact with the metal can surface.
