The invention discloses bacteriostatic paint and a production method thereof. The paint comprises the following components, in parts by weight, of 100-150 parts of phenolic resin, 100-150 parts of silicon dioxide aerogel, 50-80 parts of plant extracts, 50-60 parts of negative ion powder, 20-30 parts of nanometer titania, 30-40 parts of modified carbon nanotubes, 30-40 parts of graphene oxide, 20-30 parts of vitrified microspheres, 10-15 parts of chitosan, 3-5 parts of a surfactant, 3-5 parts of a bacteriostatic agent, 1-2 parts of a silane coupling agent and 1-2 parts of a levelling agent. Thepaint has the characters of being ageing-resistant, free from peeling and discoloration, high in weather resistance, non-toxic, odourless, good in levelling property and easy to apply, and is scrub-resistant, the original strength and quality of the paint can still be maintained after other functional components are added moderately, and the paint not only can release negative air ions for a longterm to purify air and to benefit human health, but also can restrain and sterilize bacteria.
