Textile heat-, fire- and/or smoke-proof material

Abstract

A textile heat-, fire- and/or smoke-proof material, comprising a flat, textile substrate which is coated with a polymer composition. The polymer composition containing a cross-linked silicone resin and metal pigments. The invention also relates to a method for producing a textile heat-, fire- and/or smoke-proof material, and to the use of a textile structure as a heat protector in a vehicle(s) and as fire and heat protection in a building(s).

         3 . The textile protection material for at least one of heat, fire or smoke according to  claim 1 , wherein the polymer composition contains at least one further polymer different from crosslinked polysilo-xane. 
     
     
         4 . The textile protection material for at least one of heat, fire or smoke according to  claim 1 , wherein the textile sheet-like substrate is a woven, scrim or nonwoven fabric. 
     
     
         5 . The textile protection material for at least one of heat, fire, or smoke according to  claim 1 , wherein the textile, sheet-like substrate contains fibers. 
     
     
         6 . The textile protection material for at least one of heat, fire or smoke according to  claim 1 , wherein the metal pigments are aluminum pigments. 
     
     
         7 . The textile protection material for at least one of heat, fire or smoke according to  claim 1 , wherein the metal pigments are in the form of platelets or flakes and have a maximum diameter of 1 to 100 μm, in an area, which can be determined by sieve analysis. 
     
     
         8 . The textile protection material for at least one of heat, fire or smoke according to  claim 1 , wherein the proportion of metal pigments in the polymer composition comprises at least 7% by weight. 
     
     
         9 . A method for preparing a textile protection material for at least one of heat, fire or smoke according to  claim 1 , comprising the steps:
 Providing a textile, sheet-like substrate;   applying an aqueous dispersion or an emulsion to at least a portion of the substrate, and the dispersion or emulsion comprising an emulsified or dispersed silicone resin and metal pigments;   Curing the applied dispersion or emulsion to form a coating.   
     
     
         10 . The method of  claim 9 , wherein the dispersion or emulsion is in the form of a co-dispersion or co-emulsion additionally comprising a dispersed or emulsified polymer other than polysiloxane. 
     
     
         11 . The method according to  claim 9 , wherein on only one upper surface of the textile sheet-like substrate the dispersion or emulsion is applied. 
     
     
         12 . The method according to  claim 9 , wherein the solids content of the dispersion or emulsion, at the time of application, is above 50% by weight. 
     
     
         13 . The method according to  claim 9 , wherein the dispersion or emulsion, at the time of application, has a viscosity of 500 to 40,000 mPa·s, determinable by a Brookfield method. 
     
     
         14 . The method according to  claim 9 , wherein the curing of the dispersion or emulsion is essentially effected by drying and subsequent activation in a temperature range between 100 and 300° C. 
     
     
         15 . Use of a textile protection material for at least one of heat, fire or smoke according to  claim 1  and obtainable by a method comprising the steps:
 providing a textile, sheet-like substrate; 
 applying an aqueous dispersion or an emulsion to at least a portion of the substrate, and the dispersion or emulsion comprising an emulsified or dispersed silicone resin and metal pigments; and 
 curing the applied dispersion or emulsion to form a coating 
 
       and the textile protection material being used as a heat protector in a vehicle and as a fire and heat protector in a building. 
     
     
         16 . The textile protection material for at least one of heat, fire or smoke according to  claim 1 , wherein the metal pigments are in the form of platelets or flakes or have a maximum diameter of 1 to 100 μm in an area, which can be determined by sieve analysis. 
     
     
         17 . Use of a textile protection material for at least one of heat, fire or smoke according to  claim 1  as a heat protector in a vehicle and as a fire and heat protector in a building.
