Embodiment 1

[0020] The invention discloses a lubricating oil improving agent of network lattice nanospheres, which is composed of 1.5% by weight of polyethylene glycol 200 and 98.5% of oxymolybdenum dialkyldithiophosphate. That is, polyethylene glycol 200 accounts for 1.5% of the total weight ratio of the lubricating oil improver, and oxymolybdenum dialkyl dithiophosphate accounts for 98.5% of the total weight ratio of the lubricating oil improver.

Embodiment 2

[0022] A network lattice nanosphere lubricating oil improving agent, the lubricating oil improving agent is composed of polyethylene glycol 600 and molybdenum dialkyldithiocarbamate, and its weight ratio is: polyethylene glycol 600 weight ratio is 10 %, the weight proportion of molybdenum dialkyldithiocarbamate is 90%. That is, polyethylene glycol 600 accounts for 10% of the total weight ratio of the lubricating oil improver, and molybdenum dialkyldithiocarbamate accounts for 90% of the total weight ratio of the lubricating oil improver.

Embodiment 3

[0024] A kind of network lattice nanosphere lubricating oil improving agent, this lubricating oil improving agent is made up of polyethylene glycol 6000 and dialkyl dithiophosphate oxygen molybdenum and dialkyl dithiocarbamate molybdenum, and its weight proportion is : The weight proportion of polyethylene glycol 6000 is 20%, the weight proportion of molybdenum dialkyldithiophosphate is 30%, and the weight proportion of molybdenum dialkyldithiocarbamate is 50%. That is, polyethylene glycol 6000 accounts for 20% of the total weight ratio of the lubricating oil improver, dialkylmolybdenum dithiophosphate accounts for 30% of the total weight ratio of the lubricating oil improver, and molybdenum dialkyldithiocarbamate accounts for 30% of the total weight ratio of the lubricating oil improver. 50% of the total weight ratio of oil improver.

Abstract

The invention relates to a network lattice nanosphere lubricating oil improver, which belongs to a chemical composition and relates to a composition additive for improving the performance of lubricating oil. The lubricating oil improver includes polyethylene glycol and organic molybdenum, wherein the weight proportion of polyethylene glycol is 1.5-35%, and the weight proportion of organic molybdenum is 65-98.5%, and the polyethylene glycol includes polyethylene glycol Diol 200, Macrogol 400, Macrogol 600, Macrogol 800, Macrogol 1000, Macrogol 1500, Macrogol 2000, Macrogol 4000, Polyethylene Glycol 6000, polyethylene glycol 8000, polyethylene glycol 10000 and polyethylene glycol 20000; the organic molybdenum includes dialkyl molybdenum dithiophosphate and dialkyl disulfide One or a mixture of two molybdenum carbamates. The invention can not only improve the combustion rate of fuel oil, but also greatly reduce the discharge of exhaust gas from fuel combustion.

Description

technical field [0001] The invention belongs to a chemical composition and relates to a composition additive for improving the performance of lubricating oil. Background technique [0002] At present, lubricating oil additives are mainly used in the mechanical power transmission of vehicles, ships, machine tools, etc., to reduce the mutual friction in the transmission of various components, so as to improve the performance of each component and prolong the service life. The existing lubricating oil additives mainly include anti-wear agents, metal detergents, ashless dispersants and antioxidants. In order to reduce friction loss and improve fuel efficiency, organic molybdenum is usually added to additives, such as "lubricating oil composition" published by the state with patent application number 200580032539.4, "a non-sulfur phosphorus oil-soluble organic molybdenum" with patent application number 201010508671.0 Molybdenum Additive" and "Fuel Consumption Saving Engine Oil C...
