Method for producing tritium-proof gloves

Abstract

The invention provides a method for producing a pair of tritium-proof gloves and belongs to the field of a radiation proof material. The method comprises the step of: preparing a three-layer compound rubber thin film by using a method of compounding layer by layer, wherein the outer layer is a rubber barrier layer which is good in hydrogen stopping property; the middle layer is a tritium absorption layer in which an organic hydrogen absorption agent prepared by DEB and a catalyst is dispersed; and the third layer is a rubber layer which is good in compatibility with the skin and is made of the same material as the outer layer. The gloves produced by using the method has the advantages that tritium permeating into each tritium-proof glove through surface layer rubber is fixed in the rubber layer of the middle layer of each glove, thereby achieving the tritium-proof effect; and the preparation process is simple, the tritium-proof effect is obvious and the tritium recycle and the environmental protection can be realized.

Description

technical field [0001] The invention relates to the manufacture of a radiation-proof material, in particular to a method for preparing a material used for anti-tritium gloves. Background technique [0002] The glove box is inseparable from the tritium operation, and the relatively open position of the glove box is the glove. Gloves are also the closest the operator has to tritium. Anti-tritium gloves mostly use polymer materials, and the penetration of tritium in polymer materials and long-term exposure to radiation environments will lead to a decline in material performance. Therefore, the development of tritium protective polymer materials generally needs to solve the following problems: slow down the penetration of tritium in the material, enhance the anti-β particle radiation performance of the material, reduce the chemical corrosion caused by irradiation and the action of tritium on the material, and reduce the risk of hydrogen isotope exchange. possibility.

Problems solved by technology

However, although the anti-tritium gloves mentioned in the prior art adopt a 5-layer composite structure, the function of each layer is to prevent the penetration of tritium through physical isolation, which is also the traditional method for preventing the penetration of tritium in anti-tritium gloves

The anti-tritium gloves made by physical isolation, as time goes by, tritium will always seep into the operator's side, thus harming the operator and polluting the environment, and also causing the loss of tritium
