MULTILAYER PROTECTIVE MATERIAL Russian patent published in 2001 - IPC

FIELD: procedure of textile-finishing production, in particular, finishing of heat-resistant materials for sewing of special fireproof and oil-gasoline resistant clothes imparting high physicomechanical properties to them. SUBSTANCE: multilayer protective material in the form of a pack has an external layer of heat-resistant fibres, intermediate heat-insulation layer, internal layer of cotton cloth and a waterproof layer of siloxane composition positioned between the intermediate and external layers, which jointly with the external layer makes up 0.02 to 0.05 of the thickness of the intermediate layer. Applied onto the external layer is a composition, which includes, pts. wt. : fluorine-containing rubber CKF-26,, 100; butadiene- nitrile rubber CKH-26, 10-50; chalk, 30-50; magnesium oxide, 5-15; soot PM-50 with formation of a polymeric mix, 30-50; ethyl acetate, 300-500 pts. wt. is used as a solvent of it;, 3-5 pts.wt. of bifungin is added to the solution. EFFECT: enhanced bending stability, oil-gasoline resistance, frost resistance and reduced electrolyzing and wearability. 1 tbl, 3 ex
