Abstract
A method for improving lubricating performance of lubricating oils is provided and includes: adding copper phosphate with a porous structure into a base oil, a mass percent of the copper phosphate with the porous structure to the base oil is 0.0001% ˜50%, the porous structure is one of a foam porous structure and a porous nanoflower structure. The copper phosphate with the porous structure is obtained by adding a divalent copper salt solution into an alkaline disodium hydrogen phosphate solution or alkaline phosphoric acid buffer solution and then separating a precipitate. When a ratio of a concentration of a divalent copper ion to that of a phosphate ion is 1:0.1 to 400, the porous structure is porous foam or nanoflower. The porous structure can be well dispersed in the lubricating oil for 1 hour. After adding the lubricating oil, excellent friction reduction and anti-wear is achieved.
