PURPOSE: To obtain the neutral ray absorbing and shielding material compsn. which hardly generates secondary radiations by mixing and dispersing a neutron ray absorbing material respectively at specific pts. wt. with and into a polyolefin resin, phenolic antioxidant and phosphite antioxidant.
CONSTITUTION: The neutron ray absorbing material is mixed at 1 to 500pts.wt. with and into 100pts.wt. polyolefin resin 0.2 to 5.0pts.wt. phenolic antioxidant and 0.2 to 5.0pts.wt. phosphite antioxidant. The polyolefin resin refers to plyethylene such as high density polyethylene and straight chain low density polyethylene, ethylene/vinyl acetate copolymer, polypropylene. The phenolic and phosphite antioxidants refer to phenolic and phosphite additives usually used for preventing the oxidation of the polyolefin resin. The neutron ray absorbing material is an inorg. boric acid compd., inorg. lithium compd., etc.
