Abstract
The invention discloses a formaldehyde-free UV blockboard with an antibacterial function and a preparation process thereof. The blockboard sequentially includes a substrate, an antibacterial layer, and a UV cured layer. The antibacterial layer contains a formaldehyde-removing antibacterial microsphere, and the formaldehyde-removing antibacterial microsphere includes a nanoscale polymer hollow microsphere. A water-in-oil drop permeates into a center of the nanoscale polymer hollow microsphere, the water-in-oil drop includes a bamboo vinegar at an outer layer and an aqueous sodium hydroxide solution at an inner layer, and titanium dioxide aerosol particles are dispersed in the aqueous sodium hydroxide solution.
