Abstract

The present invention relates to a binder compound based on natural oil, polymer and resin. Such binder compounds can for example be used in roof covering membranes as an environmentally friendly alternative to bituminous roof covering membranes.

Claims

exact text as granted — not AI-modified
1 - 8 . (canceled) 
     
     
         9 : A roof covering membrane comprising a binder compound containing, based on the total weight of the binder compound,
 a natural oil in a quantity of 14 to 19 weight percent,   a polymer in a quantity of 4 to 17 weight percent and selected from the group consisting of styrene-butadiene-styrene (SBS), styrene-ethylene-butadiene-styrene (SEBS), styrene-isoprene-styrene (SIS), polyisobutylene (PIB), polyhydroxybutyrate, polylactide (PLA), polyolefin, polyamide, polyester, atactic polypropylene (APP), and isotactic polypropylene (IPP) and combinations thereof, wherein the polymer does not contain a functional group selected from a carboxylic acid anhydride group, a carboxylic acid group, and an epoxy group, and   a resin in a quantity of 32 to 70 weight percent.   
     
     
         10 : The roof covering membrane according to  claim 9  wherein the resin quantity is 32 to 40 weight percent. 
     
     
         11 : The roof covering membrane according to  claim 9  further comprising an antioxidant in a quantity of 0.1 to 3 weight percent. 
     
     
         12 : The roof covering membrane according to  claim 9  further comprising an antioxidant in a quantity of 0.5 to 1.5 weight percent. 
     
     
         13 : The roof covering membrane according to  claim 9  wherein the resin is a natural resin. 
     
     
         14 : The roof covering membrane according to  claim 9  further comprising a filler in an effective quantity at a maximum of 65 weight percent. 
     
     
         15 : The roof covering membrane according to  claim 14  further comprising an antioxidant in a quantity of 0.1 to 3 weight percent. 
     
     
         16 : The roof covering membrane according to  claim 14  further comprising an antioxidant in a quantity of 0.5 to 1.5 weight percent. 
     
     
         17 : The roof covering membrane according to  claim 9  further comprising a filler in a quantity of 20 to 50 weight percent. 
     
     
         18 : The roof covering membrane according to  claim 17  further comprising an antioxidant in a quantity of 0.1 to 3 weight percent. 
     
     
         19 : The roof covering membrane according to  claim 17  further comprising an antioxidant in a quantity of 0.5 to 1.5 weight percent. 
     
     
         20 : The roof covering membrane according to  claim 9  further comprising a filler in a quantity of 32 to 40 weight percent. 
     
     
         21 : The roof covering membrane according to  claim 20  further comprising an antioxidant in a quantity of 0.1 to 3 weight percent. 
     
     
         22 : The roof covering membrane according to  claim 20  further comprising an antioxidant in a quantity of 0.5 to 1.5 weight percent.
