Abstract

Lauroyl L-arginine ethyl ester hydrochloride(LAE) was used as a bacteriostatic agent in transparent coatings.It was proved that LAE was above 0.5wt.% had excellent inhibitory effect on Staphylococcus aureus.Infrared spectra and XPS tests confirmed that there were exposed amino groups on the surface of the coatings,which proved that LAE was loaded in the coatings.The addition of LAE on the surface of the ultraviolet experiment in the range of the effective concentration of bacteriostasis had little effect on the original transmittance of the coating,the hydrophobic effect of the coating also remained basically unchanged.The adhesion and re-coating properties of LAE coatings in the concentration range of 0.5wt.%~3wt.% can meet the application requirements,and the aging resistance of the coatings was also good.
