Abstract
(EN) The purpose of the present invention is to provide a radiation-shielding material which is easy to mold and can be molded into a desired shape. This radiation-shielding material is obtained by mixing the following ingredients (1) to (4), and ingredient (1), a mixture of ingredient (2) and water, ingredient (3), and ingredient (4) are contained therein each in an amount of 5-95 wt%: (1) a composition including a polymer ingredient which comprises a homopolymer of vinyl acetate, a product of partial hydrolysis of the homopolymer, a copolymer of vinyl acetate and one or more monomers selected from the group consisting of acrylic esters, acrylamide, acrylic acid, methacrylic acid, methacrylic esters, maleic acid, maleic anhydride, and fumaric acid, or a product of partial hydrolysis of the copolymer; (2) sap; (3) a boron compound and/or a lead powder; and (4) a silicone compound.
(FR) La présente invention concerne un matériau de blindage contre les rayonnements qui est facile à mouler et qui permet d'obtenir une forme souhaitée par moulage. Le matériau de blindage contre les rayonnements est obtenu par le mélange des ingrédients (1) à (4) suivants, l'ingrédient (1), un mélange contenant l'ingrédient (2) et de l'eau, l'ingrédient (3) et l'ingrédient (4) étant chacun contenu dedans en une quantité allant de 5 % à 95 % en poids : (1) une composition contenant un ingrédient polymère qui comprend un homopolymère d'acétate de vinyle, un produit issu de l'hydrolyse partielle de l'homopolymère, un copolymère d'acétate de vinyle et d'un ou de plusieurs monomères choisis parmi les esters acryliques, l'acrylamide, l'acide acrylique, l'acide méthacrylique, les esters méthacryliques, l'acide maléique, l'anhydride maléique et l'acide fumarique, ou un produit issu de l'hydrolyse partielle du copolymère ; (2) une sève ; (3) un composé de bore et/ou une poudre de plomb ; et (4) un composé de silicone.
(JA)  本発明は、成型が容易で、任意の形状に成型可能な放射線遮蔽材の提供を目的とするものであり、本発明は、以下の(1)から(4)の成分を混合して得られる放射線遮蔽材であって、成分(1)、成分(2)及び水の混合物、成分(3)並びに成分(4)を重量%で、いずれも5~95%含んでいる放射線遮蔽材である: (1)ビニルアセテートのホモポリマー若しくはその部分加水分解物、又はビニルアセテートとアクリル酸エステル、アクリル酸アミド、アクリル酸、メタクリル酸、メタクリル酸エステル、マレイン酸、マレイン酸無水物、及びフマル酸からなる群より選ばれる一種又は二種以上のモノマーとのコポリマー若しくはその部分加水分解物からなるポリマー成分からなる組成物、 (2)樹液、 (3)ホウ素化合物、鉛粉体、若しくはホウ素化合物と鉛粉体、並びに (4)シリコーン化合物。
