Embodiment Construction

[0035] One technical feature of the invention is that the raw materials are readily available and can be directly purchased from existing products in the market; another technical feature is that the production process is simple, and the production conditions are mild and easy to implement.

[0036] Therefore, after obtaining the specific raw material composition and mass ratio, industrialized production can be quickly realized in accordance with specific production procedures.

[0037] The following examples will further illustrate the invention, but do not limit the invention in any way.

[0038] Table 1

[0039]

[0040] Note: Anti-wear test (HFRR) is a high-frequency reciprocating anti-wear test method, SH / T0765-2005

[0041] It can be seen from Table 1 that within the dosage range of each component given in the present invention, better anti-wear effects can be obtained.

[0042] The anti-wear agent of the present invention has no adverse effect on the index of diese...

Abstract

The invention provides a low-acid and efficient diesel antiwear additive and a preparation method thereof, comprising a specific preparation technology and six specific material components. Material (A) is at least one component of amide; material (B) is at least one component of amine oiliness improver; material (C) is at least one component of ester oiliness improver; material (D) is at least one antirust additive; material (E) is at least one demulsifier; and material (F) is at least one organic solvent. The antiwear additive prepared by the above components has the characteristics of goodantiwear effect, low acid and the like; the abrasion resistance is greatly improved by adding low sulphur diesel and no adverse effect is exerted on the quality indexes. The raw material components of the invention can be bought in commodity markets; and the production technology is simple and feasible.

Description

technical field [0001] The invention belongs to the technical field of petroleum product additive production. Background technique [0002] Low-sulfur diesel anti-wear agent, also known as low-sulfur diesel lubricity improver, is a petroleum product additive used to increase the lubricating performance of low-sulfur diesel products, improve the service life of diesel engines, and reduce the wear of engine components. [0003] During the operation of a diesel engine, diesel oil is used not only as a fuel for the engine, but also as a lubricant for parts such as injectors. Trace oxides, nitrides, sulfides and other polar substances and polycyclic aromatic hydrocarbons contained in diesel provide lubricity to a certain extent. As human beings have increased their requirements for environmental protection, modern diesel products should reduce the sulfur content as much as possible. Therefore, oil refineries use methods such as hydrofining to remove trace sulfur compounds in die...
