COMPOSITE PROTECTIVE MATERIAL Russian patent published in 2023 - IPC G21F1/00 

FIELD: polymers.

SUBSTANCE: composite protective material refers to polymeric materials based on siloxane rubber and can serve to protect products from ionizing, electromagnetic and radio emission. The composite protective material contains a polymer, a filler is a finely dispersed graphite powder of a uniform shape with a particle size of 0.004 mm to 0.05 mm, and a hardener is a cold curing catalyst K-68, in the following ratio, wt.%: Stirosil polymer brand A - 67.2; fine graphite powder - 30.8; cold curing catalyst K-68 - 2.0; total content of components without diluent - 100; Toluene thinner for 100 wt.% components - 67 wt.%.

EFFECT: creating a protective material having an increased attenuation coefficient.
