Abstract
The invention discloses radiation protection gloves. A film-forming material for the radiation protection gloves is natural rubber latex, butyl rubber latex or a mixture of natural rubber latex and butyl rubber latex in a certain proportion; and a filler for the radiation protection gloves is mixed slurry of PbWO4 and WO3. A preparation method for the radiation protection gloves comprises the following steps: heating and reacting WO3 and NaOH solution to obtain Na2WO4, reacting polyquaternary ammonium cationic active agent serving as a dispersant and Pb(Ac)2 solution to obtain PbWO4, grinding the WO3 and then adding ammonia aqueous solution of casein and the PbWO4 into the ground WO3, and grinding the mixture to obtain a PbWO4-WO3 composite slurry filler; and mixing the filler and the natural rubber latex, the butyl rubber latex or the mixed latex of the natural rubber latex and the butyl rubber latex to obtain filler-latex composite glue, and manufacturing the gloves by using a die to obtain a product. The gloves have better shielding effect on gamma rays, deuterium and tritium penetration besides alpha rays.
Description
1 technical field content of the present invention belongs to the inorganic-organic composite material field.
The 2 technical background peaceful utilizations of atomic energy are important development directions of world today's energy utilization.The nuclear power station of countries in the world operation has at present reached more than 400, and has many countries still building new nuclear power station.China's Qinshan nuclear power plant generates electricity by way of merging two or more grid systems, and is building and planning other nuclear power station.During utilizing, nuclear power station operation and nuclear material can produce a large amount of high, medium and low radiomaterials.How these materials with harmfulness are effectively protected the emphasis that becomes various countries people concern.Thereby the research and development of radiation resistance material are important problems of grinding, to national defence and civilian all significant.Along with industrial and agricultural production, the developing rapidly of particularly national defence scientific research, radiologic medicine and atomic energy industry, the various rays that the related personnel may touch can get more and more, and are more and more higher for the requirement meeting of radiation resistance material.The radiation proof scope is also more and more wider.To the protection of these rays, have crucial social effect and economic implications.
3 summary of the invention
The present invention is a kind of radiation protection gloves, and alpha ray, gamma-rays (high, medium and low energy) and β ray are all had shield effectiveness preferably, and inserts is formed different, and film forming matter kind difference is a little also different to laying particular stress on of different alpha ray shields.Production run comprises: the preparation of inserts, the selection of latex, the preparation of latex-inserts complex emulsions, the preparation of gloves, steps such as gloves Performance Detection.
