Description

Technical Field

[0001] The invention relates to the technical field of nuclear radiation protection materials, and in particular to a glove box protective glove for coordinated protection against radiation and chemical hazards and a preparation method thereof. Background Art

[0002] With the development of the nuclear industry, the demand for the operation and handling of radioactive chemicals is increasing day by day. Effective protective measures are needed to protect workers from radiation damage. Glove box protective gloves are widely used as an effective protective equipment. However, the actual use scenarios faced by protective gloves are very complex, including radiation, acid and alkali reagents, strong oxidizing reagents, organic reagents of different polarities, etc. Existing protective gloves are difficult to meet the use requirements in these environments, especially when radiation and chemical hazards exist at the same time. There is an urgent need for protective technology that can achieve coordinated protection against radiation and chemical hazards. At present, protective gloves usually use rubber materials as the base material, and add other functional additives to achieve the target function. For example, patent CN113223740A uses the impregnation process of chloroprene latex and adds a mixture of tungsten oxide and tungsten carbide particles as a shielding body to prepare a thin and elastic gamma-ray protective glove. Patent CN117757168B uses chloroprene rubber, EPDM rubber, and chlorosulfonated polyethylene rubber as substrates, nano-tungsten powder or nano-bismuth powder modified by silane coupling agent as shielding body, and barium sulfate as acid and alkali resistant reinforcing agent, and uses molding method to prepare protective gloves with good softness, mechanical properties and acid and alkali corrosion resistance. Patent CN116574335A prepares flexible shielding materials by blending gadolinium hydride, nano-boron carbide and EPDM rubber. As a rare earth material, gadolinium hydride can simultaneously shield neutrons and gamma rays. It can be seen that the rubber substrates currently used to prepare glove box protective gloves are mostly limited to chloroprene rubber, EPDM rubber and chlorosulfonated polyethylene rubber, and the selection of shielding components, reinforcing agents, plasticizers, chemical resistant fillers, etc. is relatively limited. The evaluation of the performance of the gloves is also mostly limited to shielding performance, mechanical properties, and acid and alkali corrosion resistance. It is still very urgent to improve the performance of gloves in the presence of radiation and complex chemical reagents.

[0003] The main component of the protective gloves in the existing radiation chemical hazard coordinated protection glove box is rubber. When in contact with chemical reagents, some challenges and problems may be encountered, resulting in a reduction in the service life of the gloves and even safety hazards. For example: (1) The radiation shielding function, chemical protection function and mechanical properties are incompatible: In order to improve the shielding performance, the increase of radiation shielding components will lead to a decrease in the chemical resistance and mechanical properties of the material. (2) Accelerated penetration: Chemical reagents swell, dissolve or corrode the glove material, causing the chemical substances to penetrate the glove material faster and reduce the protective effect. (3) Surface stickiness: Certain chemical reagents react with the glove material to cause the glove surface to become sticky, affecting the flexibility and comfort of the operator when using the gloves. (4) Hardening: Long-term contact with certain chemicals may cause the glove material to harden, reducing the flexibility and wearing comfort of the gloves. (5) Accelerated aging: The coupling effect of chemical reagents, especially reagents of different polarities, will accelerate the aging process of the glove material and shorten the service life of the gloves.

8. The preparation method according to claim 7, characterized in that: The first plasticizing time is 0.5-2 minutes; the first mixing time is 1-4 minutes; the second mixing time is 2-6 minutes, and the temperature is 100-160°C.

9. The preparation method according to claim 7, characterized in that: The second plasticizing time is 0.5-1 min; the third mixing time is 1-6 min, and the temperature is 70-100°C.
