HEAT-RESISTANT FIRE-RESISTANT MATERIAL Russian patent published in 2017 - IPC D03D1/00 D03D15/12 C08L15/02 B32B25/00 B32B25/20 

FIELD: construction.

SUBSTANCE: invention can be used in the manufacture of protective clothing designed for operation in high-risk conditions and resistant to aggressive media, in particular to a material ensuring the protection from thermal risks, sparks, and metal spatter. A heat-resistant fire-resistant multilayer material with polymer coating is described, consisting of one and a half layers of a fabric made from para-aramide fibre threads, in which the fabric is characterized by interlacing with a repeat, equal to 4 threads by the warp and to 8 threads by the weft, for the building of which more than one system of weft threads is used. The spaces between the threads are less than their diameter with the surface material density not less than 320 g/m², and the heat-resistant polymer coating of the fabric is made on the basis of fluorine rubbers and/or a silicone composition.

EFFECT: fire-resistant multilayer material based on para-aramide fibre and a polymer binder with the possibility of operation in corrosive media has been obtained.
