Complexing agent for lubricating oil for engines

Abstract

The invention discloses a complexing agent for lubricating oil for engines, comprising 10-12 wt% of dispersant, 10-11 wt% of detergent, 6-7 wt% of anti-wear agent, 13-14 wt% of anti-oxidant, 4-5 wt% of viscosity index improver, 5-6 wt% of pour-point depressant, 7-8 wt% of anti-foaming agent, 11-13wt% of anti-creaming agent, 1-2 wt% of magnesium powder, 1-2 wt% of boron powder and the balance of base oil, wherein the dispersant is polyisobutylene succinimide, the detergent is thiophosphate, the anti-wear agent is dialkyl-disulphophosphate, the anti-oxidant is dialkyl sulfide, the viscosity index improver is polyalkyl methacrylate, the pour-point depressant is polyfumaric acid, the anti-foaming agent is acrylic acid alkyl ester copolymer, and the anti-creaming agent is polyalkyloxy phenol. According to the invention, the production method is simple, economical and practical; the produced product has the advantages of low price and high quality, can prolong the life cycle of the lubricating oil, increase the anti-wear and anti-extreme pressure efficiency, raise the effects of oxidation resistance, corrosion resistance, and foaming resistance of the lubricating oil, and keep the cleanliness of the lubricating oil for a long time, and can comprehensively improve the comprehensive efficiency of the lubricating oil for engines.

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 compounding agent for engine lubricating 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, sl...

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
