Energy-saving emission-reducing nano wearproof lubricant special for heavy truck and method for producing the same

Abstract

The invention relates to a energy-saving and emission-reduction type nano abrasion-resistant lubricating oil (meeting the requirements of the specifications of API / SAE CH-4 / SL 5W / 40 and 15W / 50), which is used for engines of heavy trucks, engineering plants, large agricultural machines, ships, trains, diesel generating sets, etc. The lubricating oil comprises the components based on the weight percentage: 150N 30-68%, 100N 0-10% and 150BS 10-35% of base oil, 0-5% of viscosity modifying agent VL 800, 10-14% of molecule abrasion-resistant complex additive Z3355, 2-5% of nano abrasion-resistant restoration agent H8001, 0.1-0.5% of pour point depressant PPT148 and 10-100PPM of defoaming agent D12500. The invention is used for engines of heavy trucks, engineering plants, large agricultural machines, ships, trains, diesel generating sets and the like, can save the fuel oil by 15-25%, reduces the pollutant discharge by 30-40%, prolongs the service life of the oil by three times reaching over 20000 kilometers, and has excellent viscosity-temperature characteristics. In the high temperature and severe cold regions, the invention can be used in the four seasons; as the base oil is purer and the protection of the additive is fuller, the nano abrasion-resistant lubricating oil is more beneficial to energy-saving and emission-reduction as well as prolonging the service of the engine.

Description

technical field [0001] The invention relates to an energy-saving and emission-reducing nano-anti-wear lubricating oil (meeting API / SAE CH-4 / SL 5W / 40 , 15W / 50 specifications) Background technique [0002] The load requirements of heavy-duty trucks continue to increase, the engine speed continues to increase, and the requirements for the lubricating performance of lubricating oil are getting higher and higher. Manufacturers and users are working hard to increase the viscosity of oil products, which leads to continuous increase in operating energy consumption and pollutant emissions. The amount is larger. According to the characteristics of high-power and continuous operation of heavy-duty trucks, the present invention adjusts the main agent structure and dosage of nano anti-wear additives and molecular anti-wear composite additives, enhances the ability of oil products to repair machine parts wear, and further reduces frictional resistance. Save fuel consumption by 15-25%, a...
