Problems solved by technology

However, the current anti-wear additives of various lubricating oils are of good quality and expensive, and the effect is single. They do not improve the overall efficacy of lubricating oil while improving anti-wear and extreme pressure. Many low-priced ones have poor effects.
And with the progress of society and the development of human science and technology, engine oil must also have a great development, because the current oil change mileage itself is a huge waste of energy

Abstract

A tungsten molybdenum alloy anti-wear additive used in engine lubricating oil comprises base oil; tungsten molybdenum alloy; an antioxidant; a detergent; a dispersant; a metal passivator; an extreme pressure additive; and lecithin. The antioxidant is tributyl phosphite, the detergent is borate, the dispersant is succinate, the metal passivator is benzotriazole, and the extreme pressure additive is alkyl phosphorus containing acid ester and salt. The tungsten molybdenum alloy anti-wear additive is simple in manufacturing method, and can fully meet the requirements of environmental protection, the product use cycle is longer, lubricating oil antiwear and anti extreme pressure effects are improved, oxidation resistance, corrosion resistance, foaming resistance and other various effects of the lubricating oil can be improved, the detergency effect of the lubricating oil can be kept for a long time, and the comprehensive effects of engine lubricating oil can be fully enhanced.

Description

(1) Technical field [0001] The invention relates to a tungsten-molybdenum alloy anti-wear additive used in engine lubricating oil, in particular to a preparation scheme and a manufacturing method of a tungsten-molybdenum alloy anti-wear additive used in engine lubricating oil. (2) Background technology [0002] At present, there are many types of anti-wear additives for engine lubricating oil, especially various types of metal anti-wear additives. One of the best effects is imported, and the other is that domestic production is expensive. Some anti-wear additives have unsatisfactory effects. The main reason is Because the formulation of anti-wear additives and the use of base oil have many technical problems and specific problems of the interaction of chemical elements, and the use effect is single. Especially in recent years, there have been many inventions of various metal anti-wear additives, but people should not forget that no matter what kind of lubricating oil additiv...
