Abstract

The invention discloses a metal restoration additive for lubricating oil of an engine. The metal restoration additive is characterized by consisting of the following components in percentage by weight: 3 to 5 percent of polyisobutene, 5 to 8 percent of dialkyl dithiophosphate, 4 to 6 percent of phosphite ester, 8 to 10 percent of tert-butyl phenyl phosphate, 5 to 7 percent of alkyl methacrylate copolymer, 3 percent of sulfurized calcium alkyl phenolate, 3 to 5 percent of nanometer copper oxide powder, 2 to 4 percent of nanometer magnesium powder and the balance of base oil. A method is simple and practicable; and the prepared restoration additive for the engine powerfully functions in the restoration of various engines, has low cost and the good effects of wear resistance and fuel saving, can prolong the service life of the engine and a drain period, is safe to use and does not have any corrosion action on the engine.

Description

(1) Technical field [0001] The invention relates to a lubricating oil additive, in particular to an engine lubricating oil metal repair additive. (2) Background technology [0002] An additive is a material that imparts and enhances the performance of a lubricating oil. With the continuous development of engine technology, the introduction of various new technologies has also put forward higher requirements on the properties and performance of various lubricating oils. One of the current driving forces for the development of various types of lubricants is to protect the environment. And the current use of various lubricating oil additives has indeed improved certain performances of the engine, but it is also true that some additives have seriously affected the normal operation of the engine. Some additives cause corrosion and oxidation to the engine, and some additives form more carbon deposits on the engine. Although some additives on the market have certain effects, the...
