Synthesis of multifunctional borate additive and preparation of working liquid for WEDM

A new type of multifunctional borate additive with high hydrolytic stability,good antirust properties,good lubricity and high surface activity was synthesized from main starting materials like oleic acid,triethanolamine,boric acid and polyethyleneglycol-400.An optimal esterification condition of the additive was determined as follows based on orthogonal experiments: 5g of triethanolamine,2g of boric acid,20g of polyethyleneglycol-400 and 10g of oleic acid.A kind of stable and transparent working liquid for ...
