Abstract

See full text

An overall lead-free X-ray shielding rubber compound material. The overall lead-free X-ray shielding rubber compound material uses rare earth mixture to replace lead, simultaneously adds metal tin and compounds thereof, metal tungsten and compounds thereof and bismuth and compounds thereof as shielding main materials and is further compounded with rubber to prepare the compound material which can realize the overall shielding and the complete lead-free property within the energy range of 40-170 kVp. When rare earth and bismuth materials are used, the way of combined use of two metal element inorganic compounds and unsaturated organic complexes is adopted, and the in-situ reaction and the compounding with a polymer matrix are carried out, thereby leading the shielding element disperse phase to form nano-micro-level dispersed particles.
