聚乙二醇硼酸酯表面活性剂的无溶剂法制备及其性能研究
Solvent-free preparation and performance of polyethylene glycol borate surfactants
摘要
Abstract
Using boric acid(BA)and polyethylene glycol(PEG)as raw materials,a series of polyethylene glycol borates(PEG-BAE)were prepared by solvent-free method.The products were characterized by FT-IR.Their thermal stability was tested by TGA,and their surface activity was tested on a static surface tensiometer.Their rust-inhibiting properties were evaluated using HT300 cast iron and Q235 steel sheets.The lubricating properties of their aqueous solutions were tested on an MS-800 four-ball tester.Through single-factor experiments,the optimized synthesis conditions for PEG-BAE were determined as follows:reaction temperature of 115℃,molar ratio of PEG-400 to BA of 3.1∶1,and reaction time of 100 min.Under these conditions,a series of products were prepared with different PEGs,with esterification rates all exceeding 89%.FT-IR results indicated the presence of a C-O-B stretching vibration peak at 1107 cm-1 for PEG-BAEs with different molecular weights,confirming the formation of target products.TGA results showed that PEG-BAE exhibited good thermal stability,with weight loss only occurring at temperatures above 200℃.The results of surface tension measurement for PEG-BAEs with different molecular weights revealed that PEG-BAEs exhibited good surface activity,among which PEG-600-BAE demonstrated the lowest static surface tension of 33.89 mN/m.At a mass concentration of merely 1.5 g/L,PEG-600-BAE could meet the rust-preventative requirements;in acidic environment,at the mass concentration of 2 g/L,its corrosion-inhibition efficiency reached 90%.At the load of 25 kg,the wear scar diameter was 0.29 mm when the mass concentration of PEG-200-BAE was 1.5 g/L.Therefore,polyethylene glycol borates showed promising application as rust-preventative lubricants in water-based metalworking fluids.关键词
