It is actual now to work out new radiation protecting sheeting on the basis of a curing polymeric composition, which possesses self-glued properties, are easily mounted and dismantled and provide high tightness and low permeability. For the creation of a new self-glued radiation-protective material it is necessary to define the filler volume at which composite would be sticky enough (peel strength not less than 4 N/cm); character of a separation would be cohesive (on a material) and thus there would be no migration of softener and satisfactory resistance of fluidity. The object of investigation is a composite material, consisting of butyl rubber, industrial oil, barite and alkyl phenol-formaldehyde resin. The area of structures, which meet the requirements for a self-glued composite, is revealed. The optimal composite content is determinated. The given structure has the high filler content, necessary for the content of radiating protection against gamma radiation, and also a reserve in its self-glued properties. The given structure is possible to consider as a base for the optimization of radiation-protective sheeting with the application of other fillers, such as lead, tungsten etc.
