Anti-tritium glove and preparation method thereof

Abstract

The invention provides an anti-tritium glove and a preparation method thereof. Compound latex adopted for the anti-tritium glove is prepared from, by weight, 200 parts of butyl rubber emulsion, 0.10-0.25 part of polyoxyethylated castor oil, 0-5 parts of potassium hydroxide and 20 parts of dispersoid. The butyl rubber emulsion is prepared from, by weight, 160 parts of butyl rubber, 1.0-1.5 parts of oleic acid, 4.0-7.2 parts of potassium hydroxide, 5.5-6.4 parts of monopotassium phosphate, 35-50 parts of polyvinyl alcohol, 0.8-1.0 part of polyoxyethylene castor oil potassium soap and 94-100 parts of soft water. The dispersoid is prepared from, by weight, 4 parts of sulphur, 5 parts of accelerant Px, 10 parts of accelerant ZDC, 8 parts of zinc oxide, 2 parts of antiager DBH, 0.4 part of green pigment, 5 parts of dispersant NF, 0.8 part of stabilizer KOH, 0.1 part of carbon black, 1.5-5.0 parts of anti-tritium material and 50 parts of water. Compared with the prior art, the anti-tritium glove has the advantages that the tritium permeability coefficient, air tightness, mechanical performance, hot air aging resistance, sulfuric acid solution resistance and sodium hydroxide solution resistance are excellent, and the requirements of relevant military units are met.

Description

technical field [0001] The invention relates to a radiation-proof material, in particular to a tritium-proof glove and a preparation method thereof. Background technique [0002] As radiation protection materials, anti-tritium gloves mostly use polymer materials. Since the penetration of tritium in polymer materials and long-term exposure to radiation will lead to the decline of material performance, the development of tritium protective polymer materials generally needs to solve the following problems: slow down the penetration of tritium in materials, enhance the radiation resistance of materials performance, reduce the chemical corrosion caused by irradiation and the action of tritium on the material, and reduce the possibility of hydrogen isotope exchange. Currently used anti-tritium gloves are all made of butyl rubber with good anti-tritium radiation performance and tritium-blocking performance. [0003] At present, few manufacturers producing anti-tritium gloves can ...

AI Technical Summary

Problems solved by technology

[0003] At present, few manufacturers producing anti-tritium gloves can achieve a tritium permeability coefficient not greater than 1.50×10 ﹣7 cm 3 mm / cm 2 h. At the same time, the airtightness, mechanical properties, heat-air aging resistance, sulfuric acid solution resistance and sodium hydroxide solution resistance of the gloves can meet the requirements of relevant military units
