MATRIX ON POLYMER BASE FOR PROTECTIVE MATERIAL AND FLEXIBLE MATERIAL FOR PROTECTION AGAINST X-RAY AND GAMMA RADIATION

摘要

FIELD: nuclear equipment. SUBSTANCE: matrix includes butadiene or butadiene-nitrile and devinyl-styrene rubbers, polytetrafluorethylene and agidol proportion of butadiene or butadiene-nitrile and divinyl-styrene rubbers 1: (2.3-3.6) with following ratio of components, per cent mass: butadiene or butadiene-nitrile and divinyl-styrene rubbers 86.8-88.3; polytetrafluorethylene 9.5-10.5; agidol 2.2-2.8; Flexible material for protection against X-ray and gamma radiations has matrix including rubbers, which type and ratios is specified in matrix. Wolfram or oxides of heavy metals are used as filling agent with following proportion of components, per cent by mass: butadiene or butadiene-nitrile and divinyl-styrene rubbers 4.4-17.5; polytetrafluorethylene 0.5-2.0; agidol 0.1-0.5; wolfram or oxides of heavy metals 80.0-95.0. EFFECT: improved protective characteristics of flexible material. 2 tbl
