METHODS FOR FABRICATION OF THE FLAME RESISTANT RADIATION SHIELDS BY USING RADIATION CROSSLINKING AND THE RADIATION SHIELDS THEREBY

摘要

PURPOSE: A method of manufacturing enhanced flame retarding radiation shielding materials using radiation cross-linking and the radiation shielding materials manufactured by the same are used in an industry for the purpose of radiation shielding by improving mechanical strength. CONSTITUTION: Thermoplastic polymer and rubber resin are mixed. The thermoplastic polymer is selected among polyethylene, polypropylene, and polyisobutylene. The obtained mixture, cross-linking agents, and selective radiation shielding particles are uniformly mixed. Radiation is irradiated to the obtained mixture. A heat treatment process is performed after irradiating the radiation. [Reference numerals] (AA) Limiting oxygen index (%); (BB) Absorbed dose in electron beams (kGy)
