Abstract

The work aims to preparecurcumin ink with high transparency withcurcumin as toner, apply it to the tipping, and study activity of the curcumin ink on the tipping paper. The influence of different components of curcumin ink on adhesion and wear resistance was investigated. And the sunlight resistance, antibacterial activity and antioxidant activity of curcumin ink on the tipping paper were also investigated.It was determined that formula of the curcumin ink was 6.0wt% polyvinyl butyraldehyde, 0.75wt% curcumin, 0.6wt% adhesion promoter TB440, 0.2wt% wax powder 3620, and 92.45wt% ethanol absolute. Through the analysis of physical performance indicators, the tipping paper prepared by curcumin ink had good adhesion and wear resistance, as well as grade 4 sunlight resistance. The tipping paper had strong antibacterial effect on S. aureus, and the antibacterial rate reached 91.41% at the 20th min; while the antibacterial effect on E. coli was slightly weak. At the same time, the curcumin on the tipping paper had the ability to remove both 1,1-diphenyl-2-trinitrophenylhydrazine and diammonium 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonate) free radicals. Compared with the IC50 of curcumin, butylated hydroxyanisole and 2,6-tert-butyl-4-methylphenol, the antioxidant capacity of curcumin was stronger than that of butylated hydroxyanisole and 2,6-tert-butyl-4-methylphenol. The curcumin ink shows excellent transparency, adhesion, wear resistance, sunlight resistance and good antibacterial and antioxidant activity on the tipping paper.
