The benefits of adding antioxidants to lubricants?

In the process of production and use of lubricating oil, heating, metal, oxygen and other substances will be encountered, which will easily produce oxidized monomer. Through free radical reaction, sludge, insoluble polar gum, paint film and sediment will be produced. Therefore, in order to prevent these phenomena, Shanghai enmai suggests adding antioxidants to lubricating oil.

 

The main antioxidants of lubricating oil antioxidants are hindered phenols, alkylated diphenylamine and naphthylamine.

 

The auxiliary antioxidants are zinc Dialkyldithiophosphate ZDDP, molybdenum dialkyldithioformate modtc.

 

We suggest that the main antioxidant and auxiliary antioxidant should be added at the same time to pursue positive synergy.

 

At the same time, we also recommend that customers add light stabilizers, UV absorbers and other additives to further improve the weatherability of lubricating oil.

 

Shanghai enmai provides three kinds of general antioxidants with different physical forms, which provide excellent processing stability (phosphite antioxidant) and long-term thermal stability (phenolic antioxidant) for polymers, and effectively inhibit the degradation of polymers.

 

The antioxidants of Shanghai enmai provide a variety of optimization options for polymer stabilization. Such as antioxidant 1010, antioxidant 1076, antioxidant 168, etc. Thioesters, as co antioxidants, can decompose and neutralize hydroperoxides produced by polymer oxidation. Thioester can provide heat aging protection for polymer and improve the color stability of polymer.
