AI Technical Summary
Technical Problem
Existing maleated natural oils exhibit limited properties such as insolubility and non-dispersibility in water and alcohols, limiting their effectiveness in metalworking fluids.
Method used
A metal working fluid composition is developed comprising a reaction product of maleated natural oil with a lactam moiety having hydroxyl, thiol, or amine functional groups, optionally including additives like lubricity agents, pH-regulators, and bases, to enhance solubility and dispersibility.
Benefits of technology
The composition provides improved lubrication, cooling, and corrosion protection, extending tool life and reducing operational costs while maintaining stability and reducing foam and soap formation.
