Flame-resistant closure piece, and flame-resistant finish or coating

Abstract

Disclosed is a flame-resistant closure piece that is adapted to a corresponding closure piece such that a detachable to closure is formed. Said closure piece comprises a least one flat basic fabric ( 14 ) consisting of warp threads ( 10 ) and weft threads ( 12 ), and functional elements ( 18 ) that protrude on the front side of the basic fabric ( 14 ). The basic fabric ( 14 ) is provided with a flame-resistant finish. The disclosed flame-resistant closure piece is characterized in that the basic fabric ( 14 ) and the functional elements ( 18 ) are predominantly, preferably entirely, made of flame-resistant plastic materials.

1 . A flame-resistant closure piece, which is adapted to a corresponding closure piece such that a detachable closure is formed, said closure piece having at least one flat basic fabric ( 14 ) consisting of warp threads ( 10 ) and weft threads ( 12 ) and having functional elements ( 18 ) that protrude on the front side of the basic fabric ( 14 ), wherein the basic fabric ( 14 ) is provided with a flame-resistant finish ( 30 ), characterized in that the basic fabric ( 14 ) and the functional elements ( 18 ) are predominantly, but preferably entirely, composed of flame-resistant plastic materials. 
     
     
         2 . The flame-resistant closure piece according to  claim 1 , characterized in that the warp ( 10 ) and/or the weft threads ( 12 ) are predominantly, but preferably entirely, composed of PA66 plastic materials. 
     
     
         3 . The flame-resistant closure piece according to  claim 1 , characterized in that the functional elements ( 18 ) formed from thread material are predominantly, but preferably entirely, composed of PP plastic materials. 
     
     
         4 . The flame-resistant closure piece according to  claim 1 , characterized in that the threads ( 10 ,  12 ,  16 ) composed of PA66 or PP plastic materials have flame-retardant additives such as phosphorus compounds and/or triazine compounds and/or graphite constituents. 
     
     
         5 . The flame-resistant closure piece according to  claim 1 , characterized in that the thread-like functional elements ( 16 ) are integrated as pile threads in the basic fabric ( 14 ), which form loop-like closure elements ( 22 ,  24 ) when remaining closed and which form mushroom-like closure elements ( 28 ) when cut open and heated on their free ends. 
     
     
         6 . The flame-resistant closure piece according to  claim 1 , characterized in that the finish ( 30 ) used for the basic fabric ( 14 ) has self-adhesive properties or is provided with a separate, preferably flame-resistant adhesive layer ( 32 ) on its side turned away from the functional elements ( 16 ). 
     
     
         7 . The flame-resistant closure piece according to  claim 1 , the self-adhesive adhesive layer ( 32 ) is artificial rubber-based or acrylate-based. 
     
     
         8 . The flame-resistant closure piece according to  claim 1 , characterized in that the finish ( 30 ) is formed from a solvent-free, moisture-curing, reactive polyurethane prepolymer-based melt adhesive. 
     
     
         9 . The flame-resistant closure piece according to  claim 8 , characterized in that the melt adhesive ( 30 ) additionally contains the following components:
 10 to 90% polyester-polyol,   0 to 50% polyether-polyol,   5 to 35% polyisocyanate,   2 to 50% flame-retardant agents such as antimony- and halogen-free phosphorus compounds and/or triazine compounds, and   additives such as catalysts and stabilizers as needed.   
     
     
         10 . The flame-resistant closure piece according to  claim 1 , characterized in that the flame-resistant adhesive layer of the finish ( 30 ) has at least one acrylate compound as well as polyphosphoric acids and ammonium salts, including graphite constituents or other carbon constituents. 
     
     
         11 . A flame-resistant finish or coating for a closure piece, in particular for a closure piece according to  claim 1  that is adapted to a corresponding closure piece such that a detachable closure is formed, having at least one flat basic backing ( 14 ) and having functional elements ( 16 ) that protrude on the front side of the basic backing ( 14 ), wherein the basic backing ( 14 ) is provided with a flame-resistant finish ( 30 ), characterized in that the finish ( 30 ) is formed from a solvent-free, moisture-curing, reactive polyurethane prepolymer-based melt adhesive. 
     
     
         12 . The flame-resistant finish according to  claim 11 , characterized in that the melt adhesive additionally contains the following components:
 10 to 90% polyester-polyol,   0 to 50% polyether-polyol,   5 to 35% polyisocyanate,   2 to 50% flame-retardant agents such as antimony- and halogen-free phosphorus compounds and/or triazine compounds, and   additives such as catalysts and stabilizers as needed.
