Problems solved by technology

Fatty acid value is the most effective anti-wear additive for low-sulfur diesel oil, but carboxylic acid additives interact with high-basic value dispersants and zinc dialkyl dithiophosphates to undergo chemical changes, resulting in sludge that clogs the filter system, organic alcohols, fatty amines , The anti-wear effect of amide additives is not particularly prominent, so it is necessary to develop high-efficiency diesel anti-wear additives

Abstract

The invention discloses an anti-wear additive for low-sulfur diesel oil. The anti-wear additive for diesel oil is a polyether compound, and its molecular structure is as follows: R1-(-O-R2-)n-OR3, wherein R1 is 1- A hydrocarbon group with 24 carbon atoms, R2 is independently an alkylene group with 2-4 carbon atoms, n is 10 to 30, R3 is H or an alkyl group. The low-sulfur diesel anti-wear additive of the present invention has good anti-wear performance in low-sulfur diesel, does not contain sulfur, phosphorus, nitrogen and other impurity elements, does not interact with lubricating oil detergents and dispersants, and has certain detergency. Diesel antiwear additive with excellent performance.

Description

technical field [0001] The invention belongs to the field of diesel oil additives, in particular to a low-sulfur diesel anti-wear additive. Background technique [0002] In recent years, as environmental protection has put forward higher and higher requirements on diesel quality, the sulfur content in diesel has been strictly controlled, and the lubricity problem of diesel has gradually been exposed. The diesel lubricity evaluation test shows that most low-sulfur diesel oils have poor lubricity, and diesel with a sulfur content of less than 500ug / g may cause engine wear. PAHs, nitrogen compounds, sulfur compounds and oxides in diesel are natural lubricants. Engines using low-sulfur diesel are prone to wear and damage, reducing engine life. [0003] Diesel anti-wear additives are the most economical and effective method to solve the lubrication problem of low-sulfur diesel. Since the 1990s, people have developed a variety of diesel anti-wear additives to solve the lubricat...
