FILTERING CHEMICAL-PROTECTIVE MATERIAL Russian patent published in 2019 - IPC A62D5/00 A62B17/00 B32B25/02 B32B5/28 

FIELD: chemical protection.

SUBSTANCE: invention relates to chemical-protective materials of filtering type used for personal protective equipment and protective clothes. Disclosed is a filtering chemical-protective material based on natural, synthetic or mixed textile webs filled with powdered activated carbon mixed with polymer binder. Polymer binder used is polymer compositions based on liquid organosilicon polymers (silicones) or polymer mixtures containing at least 50 wt % silicone. Activated carbon with particle size from 30 to 150 mcm is placed inside binder. Content of coal ranges from 30 to 140 g/m². Binder containing activated carbon is applied in the form of coating on one or two sides of textile cloth with solid or discrete layer in form of hemispherical elements.

EFFECT: invention improves operational characteristics of material by reducing its rigidity while maintaining protective properties.
