PROTECTIVE GLOVES Russian patent published in 2015 - IPC B82B3/00 

FIELD: chemistry.

SUBSTANCE: in protective gloves for operators, working with source of electromagnetic radiation, which consist of tissue lining, connected with protective and external layers, protective layer is made in form of rings connected to each other and as material of which applied is non-corrosive steel or polymeric materials. External and protective layer are covered with composite material to protect against electromagnetic radiation, which consists of polymeric base, in which particles of compounds - (Fe, Si) or - Co with nanocrystalline structure with volume density (0,6÷1,4)·10^-5 1/nm³ are distributed Polymeric base for fixation of position of powder particles with nanocrystalline structure is made in from of alternating between each other structure elements, placed at angle 90° to each other, and each of elements is made in form of particles of elongated shape, located in parallel lines Particles, located on the left and on the right of it, are shifted by value, which does not exceed half of maximal particle size. The following range of values of nanocrystal volume density in amorphous matrix is optimal: higher than 0,6·10^-5 1/nm³, not less than 1,4·10^-5 1/nm³. External casing is made from X-ray protective material, which contains polymeric binding agent, catalyst, powder-like filler, based on oxides of elements with different absorbing ability in X-ray range of irradiations. As polymeric binding agent applied is low molecular cauotchouc -containing silicon, as catalyst - organometal compound from group of salts of caprylic acid and tin (IV), and filler contains oxides of rare-earth elements with serial numbers of elements 51, 58-71, yttrium oxide, antimony (III) oxide with particle size in range of values 0,5-30 mcm with the following component ratio, wt p: silicon-containing low molecular cauotchouc - 100; catalyst - 6-8; filler - 350-450. Antimony (III) oxide and Σ oxides of REE and yttrium are taken in ratio 1:1.

EFFECT: increased degree of operator protection from electromagnetic radiation.
