2. Reaction mechanism of the product The reaction mechanism of Zinc Dialkyl Dithiophosphate (ZDDP) corrosion inhibitor involves several complex processes that contribute to its excellent anti-wear and antioxidant properties. Let's delve into the detailed reaction mechanism of this important additive:
Formation of Protective Films:
When ZDDP is added to a lubricant, it undergoes reactions with metal surfaces to form protective films. The zinc cation (Zn^2+) in ZDDP reacts with metal oxide surfaces, such as iron oxide (Fe2O3), to form zinc oxide (ZnO) films. These films act as barriers, preventing direct metal-to-metal contact and reducing frictional wear.
Adsorption and Tribochemical Reactions:
ZDDP molecules adsorb on metal surfaces due to their polar nature. The alkyl groups in ZDDP interact with surface-active metals, such as iron (Fe), copper (Cu), and lead (Pb), forming strong chemical bonds. This adsorption process enhances the effectiveness of the inhibitor by providing a stable and protective surface layer.
Under high-pressure and high-temperature conditions, ZDDP undergoes tribochemical reactions. The phosphate groups in ZDDP react with metal surfaces to form iron phosphate (FePO4) and zinc phosphate (Zn3(PO4)2) compounds. These compounds have low solubility and act as solid lubricants, reducing friction and minimizing wear.
Acid-Base Reactions:
ZDDP can also undergo acid-base reactions in the presence of moisture. The dithiophosphate anion in ZDDP reacts with acidic corrosion products, such as sulfuric acid (H2SO4), generated during the combustion process. This neutralizes the acid and prevents further corrosion, protecting the metal surfaces from degradation.
Radical Scavenging:
ZDDP exhibits excellent antioxidant properties due to its ability to scavenge free radicals. The phosphorus moiety in ZDDP acts as a radical scavenger, intercepting and neutralizing reactive species generated during lubricant oxidation. This reduces the formation of corrosive by-products and helps maintain the oxidative stability of the lubricant.
Passivation of Metal Surfaces:
One of the important functions of ZDDP is the passivation of metal surfaces. The zinc oxide (ZnO) and zinc phosphate (Zn3(PO4)2) films formed during the reactions act as stable passivation layers, inhibiting the corrosion of metal surfaces. These films prevent the exposure of the underlying metal to corrosive environments, such as moisture or acidic compounds.
Synergistic Effects:
ZDDP can also interact synergistically with other additives commonly present in lubricant formulations, such as detergents and dispersants. These interactions further enhance the anti-wear and antioxidation properties of ZDDP, improving the overall performance of the lubricant.
In conclusion, the reaction mechanism of Zinc Dialkyl Dithiophosphate (ZDDP) corrosion inhibitor involves the formation of protective films, adsorption and tribochemical reactions, acid-base reactions, radical scavenging, passivation of metal surfaces, and synergistic effects. These mechanisms contribute to its exceptional anti-wear, antioxidant, and corrosion inhibition properties, making ZDDP an essential component in lubricants for various applications.
