Abstract
An engine oil dispersant, characterized in that: from a base oil; polyisobutylene succinimide; a sulfonate salt; a mixture of a diarylamine and a sterically hindered phenol; and (3) polyisobutene amine. The weight percentages of the components are as follows: 46-48% of polyisobutylene succinimide; 9-10% of sulfonate; 14-16% of a mixture of diarylamine and hindered phenol; 9-11% of polyisobutylene amine; the balance being base oil. The invention has simple preparation, is convenient and easy to implement, is economical and practical, and can keep the cleaning and dispersing effects of the lubricating oil for a long time. The lubricant oil has the advantages of long-term maintenance of the dispersion effect on initial products and sediments in soot, resin, adhesive film, carbon deposit and lubricating oil, heat and oxidation stability and good low-temperature performance, long-term maintenance of the oil quality of the lubricating oil and prolongation of the oil change period.
Description

The present invention relates to a kind of oil dope, particularly a kind of preparation scheme and preparation method of engine oil dispersion agent.
(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 dispersion agent is characterized in that: by base oil; Polyisobutenyl succinimide; Sulphonate; The mixture of diaryl-amine and two kinds of components of sterically hindered phenol; PIBA is formed.The weight percent of each component is: polyisobutenyl succinimide 46-48%; Sulphonate 9-10%; The mixture 14-16% of diaryl-amine and two kinds of components of sterically hindered phenol; PIBA 9-11%; Surplus is a base oil.
A kind of above-mentioned engine oil dispersion agent, 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 dispersion agent 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 dispersion agent, 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 oil dispersion agent is characterized in that: with base oil; Polyisobutenyl succinimide; Sulphonate; The mixture of diaryl-amine and two kinds of components of sterically hindered phenol; PIBA mixes, heat and controlled temperature between 45-55 ℃, stirred 90-240 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.
