Abstract

The invention discloses an anti-friction energy-saving additive with dispersed solution of modified nano lanthanum borate and basic oil and a preparation method thereof. The anti-friction energy-saving additive is prepared from a modified lanthanum borate nano composite material and basic oil, wherein the weight ratio of the modified lanthanum borate nano composite material to the basic oil is (5-15):(85-95); the modified lanthanum borate nano composite material is prepared from the following substances in parts by weight: 0.5-2 parts of sodium borate, 0.3-0.5 part of lanthanum chloride, 0.05-0.2 part of KH-550, 1-3 parts of oleic acid and 1-3 parts of petroleum ether. The anti-friction energy-saving additive and the preparation method thereof disclosed by the invention have the beneficialeffects that the modified lanthanum borate nanocomposite material is prepared by combination with a flotation method in the preparation process, the secondary particle-size distribution of a preparedproduct is narrow, the problem of settlement of the additive in lubricating oil is overcome, and meanwhile, the problem that a lanthanum-borate type product is decomposed when meeting water is solved; the additive shows outstanding anti-friction property in the lubricating oil, and has good dispersity in the lubricating oil; the effect of reducing the friction coefficient among workpiece equipment can be achieved, so that the effects of emission reduction, energy conservation and friction reduction and the like of the workpiece equipment are achieved.

Description

technical field [0001] The invention relates to a friction-reducing and energy-saving additive, in particular to a modified nano-lanthanum borate base oil dispersion liquid friction-reducing and energy-saving additive and a preparation method thereof. Background technique [0002] With the rapid development of transportation, mechanical equipment and other industries, as well as the shortage of fuel resources and the increasingly serious environmental problems, people's requirements for lubricating oil additives are becoming more and more stringent. Traditional lubricating oil additives cannot meet the needs of social development. [0003] The prior art proposes a method for preparing modified nano-lanthanum borate. The method is to add oleic acid to the aqueous ethanol solution of borax, stir at a constant temperature of 50-90°C for 0.5-3 hours, then add the aqueous ethanol solution of lanthanum nitrate, and keep the temperature constant Stir for 1 to 4 hours, wash the obt...
