Multi-functional polyurethane coating derived from 11 carbon oleic acids

Polyols based on renewable resources are derived from 11 carbon oleic acid, a by-product of castor oil, which is successfully synthesized through three continuous reactions: methylation, thiol-ene addition and alamide.
polyols based on 11 carbon oleic acid are used as polyols together with cashew phenol-based polyols for the preparation of polyurethane coatings. I'm
Bio-based polyols are polyols containing sulfur and nitrogen

. The structure is confirmed by FTIR, NMR and mass spectrometrometromet technology. Polyols based on 11 carbonates, together with cashew phenol-based polyols, are used as polyols for the preparation of polyurethane coatings. The properties of polyurethanes are assessed through various technologies, such as thermal re-analysis (TGA), dynamic mechanical and thermal analysis (DMTA), UTM and electrochemical research.
Significantly reduce corrosion rates
Interestingly, when bio-based polyols are mixed with phosphate-based phosphate-based polyols at different weight percentages, mechanical properties, such as material toughness, are improved. In addition, the synergy between phosphorus and bio-based polyols and elements - sulfur and nitrogen enhances the corrosion- and antibacterial properties of polyurethane coatings. The corrosion rate of prepared polyurethane coatings has dropped sharply from 3.0×10-4 per year to 1.8×10-7mm.
