The invention provides a transparent halogen-free fire-retardant paint composition, which consists of 100phr (Parts per Hundred of Resin) of adhesive, 50-400phr of solvent, 50-300phr of foaming agent, 10-200phr of carburetant, 1-100phr of carbonizing promoter and 0-100phr of auxiliary additive; wherein, the carbonizing promoter is a phosphorus-containing compound with reaction functional groups. A coat formed by the transparent halogen-free fire-retardant paint composition nearly generates no smoke when being heated but instantly generates an expanding layer of high toughness. The expanding layer is not likely to crack, does not melt, drop and droop and moreover, is capable of effectively obstructing oxygen and heat to fulfill fire-retardant effect. The paint composition has excellent compatibility and dispersibility among the ingredients, therefore has eminent transparency and can be used for the fire prevention of various buildings, furniture or in decoration without damaging the original appearance view thereof.
