▎ 摘  要

NOVELTY - Rubber product superposed and compounded by a common rubber protective layer and an anti-alpha radiation aging layer, is claimed. The thickness of a single layer of rubber products is 0.2-2 mm, and thickness of the anti-alpha radiation aging layer is 0.03-0.5 mm. USE - The product is useful for preventing alpha radiation aging. ADVANTAGE - The product realizes shielding the alpha ray on the basis of shielding the gamma/X ray or neutron; has good service life; and ensures the weight and the use flexibility of the glove are hardly influenced. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing a rubber product comprising (i) preparing the latex of the ordinary rubber protective layer and the latex of the anti-alpha radiation aging layer respectively; (ii) cleaning mold and immersing in a coagulant, drying to obtain the first intermediate mold, where the coagulant is calcium chloride, calcium nitrate, barium chloride, barium nitrate, and/or cyclohexylamine acetate and the mass concentration of the coagulant is 3-50%; (iii) dipping the first intermediate mold into the latex of the anti-alpha radiation aging layer and the latex of the ordinary rubber protective layer in sequence; and (iv) shaping the gloves, crimping, vulcanizing, demolding, washing and dryingto obtain the finished product after the immersion.
