X-RAY SHIELDING COATING Russian patent published in 2006 - IPC G21F1/12 B32B27/38 

FIELD: roentgen-ray shielding materials.

SUBSTANCE: proposed X-ray shielding coating has sublayer incorporating cured and plasticized epoxy-containing compound and basic elastic X-ray shielding layer also based on epoxy-containing binder; curing agent from group of cold-curing agents; shielding filler in the form of powdered mixture of rare earth element oxides or mixture of rare earth element oxides with antimony oxide (III), or mixture of rare earth element oxides with tungsten or its compounds, proportion of ingredients being as follows, mass percent: binder, 13.3 - 20.8; shielding filler, 78.6 - 86.3; amine curing agent, o.4 - 0.6. In addition, it has solvent which is essentially mixture of acetic esters, aliphatic and aromatic solvents in the amount of 30 - 40 mass percent per every 100 g of basic X-ray shielding material. Shielding filler content of basic polymerized layer ranges between 78.5 and 88.7 mass percent.

EFFECT: enhanced effectiveness of shielding personnel and patients, improved mechanical and adhesive properties of material.
