The invention discloses novel flexible lead-radiation-free protective clothing. A protective layer is arranged on the surface of the protective clothing, the protective layer is made of a base material and filler through the drum mixing technology and the rolling technology, the base material comprises a silane coupling agent, an antioxidant, polyvinyl alcohol, rubber softening oil, dioctyl esterand a polyethylene rubber prepolymer, and the filler comprises tantalum powder, tungsten powder, iron powder and platinum powder. The protective clothing has the advantages that the design is reasonable, the structure is simple, tantalum, tungsten, barium and other non-toxic and environment-friendly materials are utilized to serve as the functional filler, and the material attenuation coefficient,gamma/X ray shielding performance and radioactivity of tantalum and tungsten are equivalent to those of lead so that radiation hazards can be effectively protected. According to the method, through the scientific ratio of various functional elements, and the defect, related to energy absorption, of a single functional material is corrected and overcome; besides, tantalum, tungsten, barium and thelike serve as the shielding material, the weight of the shielding material is only one fifth that of traditional lead clothes, the protective clothing is more comfortable for users, moving of hands and feet is facilitated, and the heat dissipation performance is good.
