Abstract
The invention provides a total-efficiency anti-wear additive for engine lubricating oil. The total-efficiency anti-wear additive is prepared from the following components in parts by weight: 3-15 parts of a viscosity modifier, 25-40 parts of an anti-wear agent, 17-45 parts of base oil and 3-5 parts of a rust and oxidation resistant agent. The total-efficiency anti-wear additive provided by the invention can improve the anti-wear characteristic of the engine lubricating oil and can not lead to the decrease of other physical indicators of the engine lubricating oil. In addition, the preparation process of the total-efficiency anti-wear additive is simple and is convenient to use.
Description
Technical field
The present invention relates to a kind of additive for wear resistance of lubricating oil, especially a kind of full effective type engine lubricating oil wear preventive additive.
Background technology
Along with advancing by leaps and bounds of car engine manufacturing technology, just had higher requirement to the performance of engine lubricating oil, during for vehicle time-based maintenance, after changing engine lubricating oil, the wear preventive additive added can make the over-all properties of lubricating oil significantly promote.But wear preventive additive sold in the market is all based on single lifting extreme-pressure anti-wear and anti-attrition characteristic; can not the characteristic of General Promotion lubricating oil; even affect other physicochemical properties of lubricating oil, so that cause abnormal oil level loss or engine high temperature noise to become large or low temperature engine start difficulty.
Summary of the invention
The object of the invention is to solve existing wear preventive additive, after being added to engine lubricating oil, cannot General Promotion or maintain outside engine lubricating oil original physicochemical property, cause engine lubricating oil even on the contrary except antiwear characteristics promotes, the problem of the decline of other main physical and chemical indexs, provides a kind of full effective type engine lubricating oil wear preventive additive.
The present invention is achieved through the following technical solutions:
