Embodiment

[0075] Example : Preparation of radiolysis resistant gloves of the present invention

[0076] The glove of the present invention is obtained by the following method, it comprises with fabric layer (namely DYNEEMA  , a polyurethane layer reinforced with high tenacity polyethylene fabric sold by DSM.

[0077] First, a step of soaking the mold in an organic solvent solution of polyurethane (for example, N,N-dimethylacetamide, dimethylformamide or tetrahydrofuran) or a solution obtained by dissolving polyurethane in a mixture of several organic solvents is carried out, which The mold has the shape and size of a hand.

[0078] Any polyurethane known to those skilled in the art that is soluble in an organic solution and forms a thin film after evaporation of the solvent can be used. As examples, mention may be made of polyurethanes of the aromatic or aliphatic, polyester or polyether type. However, these examples are not limiting, and in addition to the above-mentioned solubili...

Abstract

The invention concerns a glove having high mechanical performance, and high resistance to chemical products and / or radiolysis, characterised in that it comprises one or several elastomer layers, identical or different, obtained from solutions of said elastomers in one or several organic solvents or in water, said layers being reinforced, on one or several parts or on the entire internal surface of the glove, with a fabric with high mechanical strength. The invention also concerns a method for making said glove and its uses.

Description

technical field [0001] The present invention relates to a glove with high mechanical properties, high chemical resistance and radiolysis resistance, and a process for the production of such a glove. Background technique [0002] For use in the nuclear industry, various types of gloves have been disclosed. [0003] In particular, US 5 165 114 to Siemens AG discloses gloves which are particularly suitable for fitting on glove boxes containing radioactive materials. These gloves are formed by stacking the following layers from the inside to the outside of the glove: a layer of polyurethane, a layer of rubber (such as chlorosulfonated polyethylene or ethylene-propylene copolymer), a layer formed of a mixture of lead oxide and polychloroprene. layer (for radiation protection) and a further layer of rubber and a further layer of polyurethane which prevents the polyurethane from reacting with lead oxide. These gloves, although they are suitable for protection...
