METHOD FOR MANUFACTURING LAMINATED X-RAY SHIELDING MATERIAL Russian patent published in 2006 - IPC G21F1/12 

FIELD: manufacture of roentgen-ray shielding materials.

SUBSTANCE: proposed method includes joining of material layers and curing to produce stack of woven and X-ray shielding material layers by mixing ingredients of cold-hardening X-ray shielding composition. X-ray shielding composition incorporates silicone rubber as binder, shielding filler made of oxide of rare-earth elements mixed up with antimony oxide (III), catalyst, polyamine, and modifying agent, proportion of ingredients per every 100 parts by weight of silicone binder being as follows: epoxy-containing hydrocarbon, 5.0 - 15.0; ortho-phthalate and monatomic alcohols, 0.5 - 3.0; rare-earth element oxides, 160 - 180; antimony oxide (III), 200 - 210; catalyst, 6.0 - 8.0; polyamine, 0.6 - 3.0. Prior to producing stack of fabric layers material is impregnated with organic solution of organometallic compound out of group of organic tin salts. X-ray shielding composition is prepared by sequential mixing up of silicone binder with modifying agent, then catalyst and hardener, followed by their mixing with filler to obtain viscous paste, then catalyst and curing agent (polyamine) which are added to viscous paste just prior to applying the latter to finished woven material. Stack obtained is subjected to compression molding and hardening.

EFFECT: facilitated manufacture.
