Abstract

An engine oil deposit control additive comprises base oil, sterically hindered phenol, polyisobutylene maleimide, calcium base phenoxide, liquid vitamin (E), barium hydroxide and glyceryl monooleate. 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 engine oil deposit control agent can maintain and control sediment 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 present invention relates to a lubricating oil additive, in particular to a preparation scheme and a manufacturing method of an engine oil deposit control additive. (2) Background technology [0002] In order to prolong the life of various types of engines and various types of machinery, all types of modern equipment must achieve excellent lubrication, because lubrication plays a lot of good roles, and lubricating oil must achieve: cooling, cleaning and suspension at the same time as lubrication, Protects metal surfaces from corrosion. Lubricating oil is composed of base oil and various additives. The 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 properties, and the existing technology is viscosity, viscosity index, pour point and resistance. Oxidation, as well as the anti-wear and extreme pressure tha...
