Abstract
An engine lubricating oil dispersing additive is characterized by comprising components of, by weight, 45-47% of polyisobutene-bis-succinimide, 8-10% of sulfurized calcium alkyl phenolate, 9-10% of polyisobutene amine, 12-14% of a mixture of diarylamine and sterically hindered phenol and the balance of base oil. The engine lubricating oil dispersing additive of the invention is simply prepared, convenient, economical and practical, and keeps a clear disperse effect of a lubricating oil for a long time; besides the engine lubricating oil dispersing additive can keep disperse efficacy on soot, resin, coating, carbon deposit, an initial stage product of deposit of the lubricating oil and the deposit for a long time, has heat and oxidation stability, good low temperature performance, and can maintain oil product quality of the lubricating oil for a long time and prolong an oil change period.
Description
(1) technical field
The present invention relates to a kind of oil dope, particularly a kind of preparation scheme and method of manufacture of engine lubrication oil dispersant.
(2) background technology:
The main effect of dispersion agent is to disperse soot, resin, glued membrane and carbon deposit, and settling initial stage product and throw out.In order to play useful effect, dispersion agent also should possess other performance, and these performances comprise the peace cave property and the good low-temperature performance of heat and oxidation.If the heat-resistant quality of dispersion agent is poor, can decomposes, thereby lose the harmful product that connects and suspend and to exist.The oxidative stability difference can make dispersant molecule change, and self also can form settling.This also is the unsettled principal element of present engine quality of lubrication oil.The present mover profit oil produced of domestic production merchant to the using and make all and can not reach ideal effect of various additives, and costs an arm and a leg.
(3) summary of the invention
The objective of the invention is to the problem that exists in the above-mentioned technology; Provide a kind of price low, quality is high, can disperse soot fully; Resin; Glued membrane and carbon deposit, and settling initial stage product and settling, and possess the engine oil dispersing additive of heat and the stability of oxidation and good low-temperature performance simultaneously.
Technical scheme of the present invention:
A kind of engine oil dispersing additive is characterized in that: by base oil; The two butyryl imines of polyisobutene; Alkyl monosulfide powder calcium; PIBA; The mixture of diaryl-amine and two kinds of components of sterically hindered phenol is formed.The weight percent of each component is: the two butyryl imines 45-47% of polyisobutene; Alkyl monosulfide powder calcium 8-10%; PIBA 9-10%; The mixture 12-14% of diaryl-amine and two kinds of components of sterically hindered phenol; Surplus is a base oil.
A kind of above-mentioned engine oil dispersing additive, it is characterized in that: base oil is: 150BS, M14,400SN, 500SN, 5 centistokes, 10 centistokes subtract four lines any two kinds of components or three kinds of components wherein and mix, and its weight quota is 1: 1 or 1: 1: 1.
A kind of above-mentioned engine oil dispersing additive is characterized in that: the weight quota of diaryl-amine and two kinds of components of sterically hindered phenol is 1: 1.And should mix in advance.Temperature is controlled between 40-45 ℃ during mixing, stirs to get final product in 120 minutes.
A kind of above-mentioned engine oil dispersing additive, it is characterized in that: product of the present invention is equally applicable to gear oil and transmission fluid.
A kind of preparation method of above-mentioned engine lubrication oil dispersant is characterized in that: with base oil; The two butyryl imines of polyisobutene; Alkyl monosulfide powder calcium; PIBA; The mixture of diaryl-amine and two kinds of components of sterically hindered phenol mixes, heat and controlled temperature between 40-50 ℃, stirred 120-300 minute, promptly go out product after the filtration.
Advantage of the present invention:
The present invention prepares simply, and is convenient and easy, economical and practical, can keep the peace and quiet dispersion effect of lubricating oil for a long time.Keep for a long time soot, resin, glued membrane, carbon deposit, and sedimental initial stage product and sedimental dispersion effect in the lubricating oil, and possess heat and the stability of oxidation and good low-temperature performance simultaneously, keep the oil quality of lubricating oil for a long time, the prolongation drain period.
