Problems solved by technology

However, the current various lubricating oil additives are of good quality and expensive, and many low-priced ones are not effective.
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

The invention relates to a composite agent for engine oil. The composite agent comprises, by weight, 10-12% of a dispersant, 11-12% of a detergent, 7-9% of a wear resisting agent, 13-14% of an antioxidant, 5-6% of a viscosity index improver, 4-5% of a pour point depressant, 7-8% of a defoamer, 9-11% of a demulsifying agent, 1-2% of metallic chromium powder, and the balance base oil, wherein the dispersant is polyisobutylene bissuccinimide; the detergent is a phenate; the wear resisting agent is a metal dialkyl dithiophosphyl dithiophosphate; the antioxidant is acrylate; the viscosity index improver is polymethacrylate; the pour point depressant is alkylnaphthalene; the defoamer is polydimethylsiloxane; and the demulsifying agent is a polyalkoxy polyol. A manufacturing method of the composite agent of the invention is simple, economic and utile; and the prepared composite agent has the advantages of low price, high quality, prolongation of the service period of lubricating oil, improvement of the wear resistance and the extreme pressure resistance of the lubricating oil, improvement of various efficacies of the oxidation resistance, the corrosion resistance and the foaming resistance of the lubricating oil, and permanent maintenance of the clean effect of the lubricating oil, so comprehensive efficacies of the lubricating oil are comprehensively improved.

Description

(1) Technical field [0001] The invention relates to a lubricating oil additive, in particular to a preparation scheme and a manufacturing method of a composite agent for engine oil. (two) background technology: [0002] Engine oils account for almost half of the lubricating oil market and thus receive great attention. The main function of engine oil is to extend the life of the machine and ensure the normal operation of the machine under different speed, temperature and pressure conditions. At low temperature, lubricating oil should have good fluidity to ensure the lubrication of moving parts in time; at high temperature, lubricating oil should be able to better isolate moving parts to reduce wear. Lubricating oil plays a lubricating role by reducing friction and taking away heat from the friction surface. The pollutants accumulated during the operation of the engine will affect the normal operation of the engine. These pollutants may be abrasive particles, sludge, carbon d...
