Example Embodiment

[0019] Example 1

[0020] Step 1: Preparation of hydrogen absorbent. The hydrogen absorbing agent was prepared according to the ratio of DEB and carbon catalyst (containing 5% by weight of Pd on the carbon) powder at a ratio of 3:1, put into a ball mill for mixing and ball milling for 1 hour.

[0021] Step 2: Preparation of the first film. Mix the natural rubber mortar and vulcanizing agent at a mass ratio of 150:1 and stir them thoroughly. The vulcanizing agent here can be sulfur powder, zinc oxide, etc., and then put the container in a 50℃ water bath for 50 minutes, and finally put the rubber Pour the slurry into the mold and let it stand at room temperature. After the surface fluidity of the glue decreases, the mold is placed in a 45°C thermostat, and the mold is taken out after about 20 minutes to obtain the first film.

[0022] Step 3: Disperse the hydrogen absorbent. The natural rubber mortar and vulcanizing agent are mixed according to the mass ratio of 150:1 and fully sti...

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.
