The invention discloses an antibacterial formaldehyde-free UV blockboard and a preparation technology thereof. The blockboard comprises a base material, an antibacterial layer and a UV curing layer which are sequentially arranged, wherein the antibacterial layer contains formaldehyde removing and bacteria resisting microspheres; each formaldehyde removing and bacteria resisting microsphere comprises a nanometer polymer hollow microsphere of which the center is permeated by water-in-oil droplets; each water-in-oil droplet comprises bamboo vinegar liquid at the outer layer, and a sodium hydroxide water solution at the inner layer; and titanium dioxide aerosol particles are dispersed in the sodium hydroxide water solutions. According to the antibacterial formaldehyde-free UV blockboard, the bamboo vinegar liquid is capable of absorbing volatile harmful gas such as formaldehyde and has spectral sterilizing efficiency to bacteria and fungus; the sodium hydroxide water solutions at the innerlayers are capable of quickly catching formaldehyde; the titanium dioxide aerosol particles are capable of oxidizing formaldehyde molecules caught by the sodium hydroxide water solutions; the water phase and the oil phase are coordinately matched with each other to continuously clean volatile harmful gas such as formaldehyde, and thus harmful bacteria and fungus can be continuously exterminated and inhibited.
