FILTERING AND SORBING SELF-DECONTAMINATING MATERIAL FOR PERSONAL PROTECTIVE EQUIPMENT FROM IMPACT OF ORGANIC PHOSPHORUS COMPOUNDS Russian patent published in 2008 - IPC B01J20/22 B01D39/00 A62B23/02 

FIELD: technological processes.

SUBSTANCE: material has an upper layer designed to prevent access of liquid toxic agent and provided with polyurethane or fluoroolefin component, middle sorbing and self-decontaminating layer that includes ferment with organophosphatehydrolase properties and cross-linked acrylate and lower layer made of woven or nonwoven cellulose containing material designed for contact with skin; where all layers are glued at the following elements ratio (mass percent): membrane and woven component - 10.3-21.4; cross-linked acrylate - 12.7-21.4; polypeptide with organophosphatehydrolase activity - 0.00125-0.4 (by protein); buffer - 7.1-44.8; nonwoven/woven cellulose containing component - 7.4-21.4; antiinfection agent - 0-1.2; adhesive - up to 100 (of total weight of material).

EFFECT: material ensures nonoccurence of vapors of highly toxic organic phosphorus compounds behind the layer of protective material and can be stored for a long period without alteration of maintenance of protective properties.
