Abstract

A deposit control agent added in lubricating oil comprises base oil, zinc dialkyldithiophosphates, polyisobutylene amine, alkyl salicylate, liquid vitamin (E), double fat and calcium 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, and has simple preparation method, low price, prominent antioxidant effect, enhanced corrosion resistance and obvious cleaning effect. The engine oil deposit control agent 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

(1) Technical field [0001] The invention relates to a lubricating oil additive, in particular to a preparation scheme and a manufacturing method of a deposit control agent added to lubricating oil. (2) Background technology [0002] In order to prolong the service life of various engines and various machinery, all kinds of modern equipment must achieve excellent lubrication, because lubrication has played many good roles, and at the same time, lubricating oil must achieve: cooling, cleaning and suspension, Protects metal surfaces against corrosion. Lubricating oil is composed of base oil and various additives. Base oil is the carrier of various additives, and at the same time plays the role of basic lubricating oil, and the function of various additives is to improve lubrication while adding new performance, while the existing technology is viscosity, viscosity index, pour point and anti-corrosion Oxidation resistance, as well as the anti-wear and extreme pressure resistan...
