Acid phosphate amine salt is a category of oil-soluble lubricant additives synthesized through the neutralization reaction between acid phosphate esters and amines of different structures. The properties of the final product can be adjusted by changing the types of raw material phosphate esters and amines, which allows it to be adapted to the performance requirements of various lubricating oil formulations.

In terms of core functions, acid phosphate amine salt has multiple excellent properties that are important for lubricant performance. First, it acts as an efficient anti-wear agent and extreme pressure agent. Under boundary lubrication conditions, it can adsorb on the metal surface to form a dense protective film, which reduces direct friction between metal parts and prevents severe wear, scratch and seizure of friction pairs under heavy load. Second, it has good corrosion inhibition and rust prevention effects. It can isolate the metal surface from corrosive media such as moisture and acidic substances generated during equipment operation, effectively preventing metal corrosion and rusting, especially suitable for protecting equipment in humid environments or during long-term idle periods. Third, it shows good compatibility with other lubricant additives such as zinc dialkyldithiophosphate and sulfurized isobutylene, and can produce a synergistic effect when compounded, further improving the overall performance of lubricating oil.

This additive is widely used in gear oils, hydraulic oils, cutting fluids and industrial lubricants, and is especially suitable for lubrication scenarios of precision mechanical components and equipment operating under harsh conditions, playing a key role in extending the service life of equipment and reducing maintenance costs.
