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 antiwear additive added in an engine oil is composed of a base oil, a tungsten-molybdenum alloy, an antioxidant, a clearing agent, a dispersant, a metal deactivator, an extreme-pressure additive and lecithin. The antioxidant is phosphoric acid ester; the clearing agent is phosphate; the dispersant is succinate; the metal deactivator is benzotriazole; the extreme-pressure additive is alkyl containing phosphate and salt. A manufacturing method is simple, requirements of environmental protection are fully met, the product use cycle is longer, antiwear and extreme pressure resistant efficacies of a lubricating oil are improved, at the same time, various efficacies of oxidation resistance, corrosion resistance and foaming resistance of the lubricating oil are improved, a clean effect of the lubricating oil is kept for a long time, and the comprehensive efficacies of the engine lubricating oil can be completely enhanced.

Description

(1) Technical field [0001] The invention relates to a tungsten-molybdenum alloy anti-wear additive added to engine oil, in particular to a preparation scheme and a preparation method of the tungsten-molybdenum alloy anti-wear additive added to engine 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 additives are used to make th...
