Abstract

A deposit control agent added in lubricating oil is composed of base oil, zinc dialkyldithiophosphates, hindered phenol, pyrrolidine dione, calcium base carbolate, liquid vitamin (E) and sodium hydroxide. The scheme provided by the invention is applicable to all types of engine lubricating oil, and is also suitable for various types of lubricating oil, hydraulic oil and crankcase oil for machinery and equipment. The product of the invention is economical and practical, has simple preparation method, low price, prominent antioxidant effect, enhanced corrosion resistance and obvious cleaning effect. The deposit control agent added in lubricating oil can maintain and control deposit generation, suspend the formed aggregates, modify soot particles, prevent agglomeration, decrease the interface capabilities of polar substances to prevent the adsorption on the surface of metal and prolong oil change period, and has comprehensive performance better than the congeneric products.

Description

Deposit Control in a kind of oil addition

(1) technical field

The present invention relates to a kind of lubricating oil additive, particularly preparation scheme and the manufacture method of the Deposit Control in a kind of oil addition.

(2) background technology

In order to extend the life-span of all kinds of engines and various machineries; it is splendid lubricated that modern various kinds of equipment must reach, because lubricated, played a lot of good effects, and lubricating oil must reach in lubricated simultaneously: cooling, clean and suspend; protection metallic surface, prevents corrosion.Lubricating oil is comprised of base oil and various additives.Base oil is the carrier of various additives, and play basic lubricating oil effect simultaneously, and the function of various additives is to improve to increase new performance lubricated time, and existing technology is viscosity, viscosity index, pour point and oxidation-resistance, and the wear-resistant and anti-extreme pressure all pursued of existing all kinds of manufacturer.But a lot of people have ignored comprehensive effect, particularly oxidation-resistance of lubricating oil, erosion resistance and suspending power and peace and quiet effect.Although all kinds of effects of lubricating oil are all very important, in automobile oil, prevent corrosion and by the insoluble pollutent in suspension lubricating oil with to keep the clean of surface be most important.But current can have good efficacy, the various greasy filth that can suspend completely, resin, adds film and glued membrane and hard sedimental additive does not almost have, and additive out of the ordinary is expensive, and effect is not obvious.

(3) summary of the invention

The object of the invention is the problem existing in above-mentioned technology, provide a kind of anti-oxidant and anticorrosive effect is obvious, peace and quiet remarkably productive, all kinds of settlings that can keep for a long time suspending in lubricating oil are also combined with colloidal particle simultaneously, prevent from reuniting and dissolving, modification soot particles also can reduce the abrasive material causing due to particulate and grind the increase of changing with viscosity.Deposit Control in the simple oil addition of technique.

Technical scheme of the present invention:

A Deposit Control in oil addition, essential characteristic is: by base oil; Sulphur phosphorus alkylphenol zinc salt; Shielding phenol; Succinimide; Calcium base phenates; Liquid vitamin (E); Sodium hydroxide forms; The weight percent of each component is: sulphur phosphorus alkylphenol zinc salt 2-13%; Shielding phenol 8-26%; Succinimide 6-32%; Calcium base phenates 6-24%; Liquid vitamin (E) 3-9%; Sodium hydroxide 3-6%; Surplus is base oil.

A Deposit Control in above-mentioned oil addition, essential characteristic is: base oil is for subtracting four lines, 5 centistokes, 10 centistokes, 500SN, M14,32#, 46#, 68#, any two kinds of components or three kinds of components in base oil combine, and the weight quota ratio of each component is 1: 1 or 1: 1: 1.Also can be by 150BS and above-mentioned four lines that subtract, 5 centistokes, 10 centistokes, 500SN, M14,32#, 46#, any one component of 68# combines, and the weight quota ratio of two kinds of components is 1: 2.Also can be by 500BS and above-mentioned four lines that subtract, 5 centistokes, 10 centistokes, 500SN, M14,32#, 46#, two kinds of components arbitrarily of 68# combine, and the weight quota ratio of three kinds of components is 1: 1: 1.

A manufacture method for Deposit Control in above-mentioned oil addition, essential characteristic is: by base oil; Sulphur phosphorus alkylphenol zinc salt; Shielding phenol; Succinimide; Calcium base phenates; Liquid vitamin (E); Sodium hydroxide, should add weight percent metering by each component, mixes, and heats and controls temperature between 55-75 ℃, stirs 60-360 minute, goes out product of the present invention after filtration.

A Deposit Control in above-mentioned oil addition, essential characteristic is: the present invention program is applicable to all kinds of cylinder oils, and is applicable to all kinds of lubricating oil for machineries and hydraulic efficiency oil equally, crankcase oils.

Advantage of the present invention: product economy of the present invention is practical, and preparation scheme is simple, and finished product price is lower, anti-oxidation efficacy is outstanding, and resistance to corrosion strengthens, and cleaning efficacy is obvious.The sedimental generation of retentive control for a long time, the aggregate that suspends and formed, modification soot particles, prevents from reuniting, and reduces the interface ability of polar material, prevents that it is in the absorption of metallic surface.Extend the drain period, over-all properties is all higher than like product.
