ZDDP: The Accidental Additive - Prospector by UL

ZDDP was first introduced as a lubricant additive in 1941, when three different companies¡ªLubrizol, American Cyanimid, and Union Oil Co.¡ªfiled patents with claims of corrosion and oxidation inhibitors in engine oils. 2 It was likely that ZDDPs were first used in engine lubricants in the late 1930s. 3. In the late 1940s, V8 engines with

The research shows that 2,6-Di-tert-butyl-4-methylphenol (BHT) can be used as an antioxidant in combined additives to reduce the antioxidant reactions of ZDDP, thus improving the anti-wear efficiency of ZDDP and further enhancing the anti-wear performance of the grease. Moreover, BHT and ZDDP have a synergistic effect on the high temperature

Synergistic and Competitive Effects between Zinc

1. Introduction In recent years, due to the increasing demand for low-viscosity engine oils [ 1 ], zinc dialkyldithiophosphate (ZDDP) as a conventional lubricating additive has been widely used. There is a need for ZDDP to reduce the friction and wear of moving parts to improve engine efficiency [ 2 ].

Zinc dialkyldithiophosphate ( ZDDP) is a well-known additive used in lubricating oils because of its multifunctional anti-wear (AW), extreme pressure (EP) and antioxidant properties. Nowadays, the harmful effect of ZDDP molecule on catalytic converter limits its use as an anti-wear additive for Internal Combustion Engine (ICE) oil.

Antiwear Behavior of ZDDP and Fluorinated ZDDP in the Presence

The anti-wear additive zinc dialkyl dithiophosphate (ZDDP), which is also an antioxidant, is one of the most important components of engine oil additives. ZDDP is a major source of phosphorus. One way to reduce phosphorus levels is to replace ZDDP with new environmentally friendly antiwear agents that have similar or superior wear performance compared to ZDDP.

Zinc dialkyldithiophosphates (ZDDP) is a type of multi-functional lubricant additive playing the roles of dispersion, anti-oxidation, anti-wear and friction modification [5¨C7]. The extensively accepted anti-wear mechanism of ZDDP is that a layer of tribofilm with low hardness and elastic modulus is generated on the contacted substrate surfaces of friction pairs during sliding process [8].
