Embodiment 1

[0011] An engine repair additive consisting of base oil; polyisobutylene; dialkyl dithiophosphate; phosphite; tert-butylated phenyl phosphate; alkyl methacrylate copolymer; sulfurized alkyl powder calcium . Base oil 150BS and 10 centistokes. The weight ratio of each component is 1:1; the weight percentage of each component is polyisobutylene 3%; dialkyl dithiophosphate 6%; phosphite 4%; tert-butylated phenyl phosphate 10% ; Alkyl Methacrylate Copolymer 4%; Calcium Sulfurized Alkyl Powder 2%. Base oil 71%. Mix the above base oil; polyisobutylene; dialkyl dithiophosphate; phosphite; tert-butylated phenyl phosphate; Heat and control the temperature at 55-60°C and stir for 180 minutes. This product is obtained after filtering. Add this product to the engine lubricating oil tank at a ratio of 3%, and draw the following conclusions:

[0012] 1. It can increase the extreme pressure and anti-wear index by more than 45%, and reduce the diameter of long-wear wear spots by more tha...

Abstract

The invention relates to an engine repairing additive. The engine repairing additive is basically characterized by consisting of the following components in percentage by weight: 3 to 6 percent of polyisobutene, 6 to 8 percent of dialkyl dithiophosphate, 4 to 6 percent of phosphite ester, 10 to 12 percent of tertiary butyl phenyl phosphate, 4 to 5 percent of methacrylic alkyl ester copolymer, 2 percent of thioalkyl calcium powder and the balance of base oil. A preparation method of the engine repairing additive is simple and practical. The prepared engine repairing additive has strong repair effects on various engines. The prepared product has low cost, high efficiency and wear-resistant and fuel oil-saving effects, can prolong the service life of the engine and the fuel oil changing period, is safe to use, and has no corrosion effect on the engine.

Description

(1) Technical field [0001] The invention relates to a lubricating oil additive, in particular to an engine repair additive for repairing an engine. (2) Background technology [0002] An additive is a material that imparts and enhances the performance of a lubricating oil. With the continuous development of engine technology, the introduction of various new technologies has also put forward higher requirements on the properties and performance of various lubricating oils. One of the current driving forces for the development of various types of lubricants is to protect the environment. And the current use of various lubricating oil additives has indeed improved certain performances of the engine, but it is also true that some additives have seriously affected the normal operation of the engine. Some additives cause corrosion and oxidation to the engine, and some additives form more carbon deposits on the engine. Although some additives on the market have certain effects, t...
