Binder Compound

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.

1 . Binder compound comprising
 natural oil in a quantity of 14 to 19 w. %; and   polymer in a quantity of 4 to 17 w. % 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), polyolefins, polyamides, polyesters, atactic polypropylene (APP) and isotactic polypropylene (IPP) and combinations thereof, wherein said polymer comprises no functional group selected from a carboxylic acid anhydride group, a carboxylic acid group and an epoxy group; and   resin in a quantity of 32 to 40 w. %.   
     
     
         2 . Binder compound according to  claim 1 , comprising an antioxidant in a quantity of 0.1 to 3 w. %, more specifically 0.5 to 1.5 w. %. 
     
     
         3 . Binder compound according to  claim 1 , wherein the resin is a natural resin. 
     
     
         4 . Binder compound according to  claim 1 , comprising a filler in a quantity of maximum 65 w. %, more specifically a quantity of 20 to 50 w. %, even more specifically a quantity of 32 to 40 w. %. 
     
     
         5 . Roof covering membrane comprising the binder compound according to  claim 1 . 
     
     
         6 . Road surfacing compound comprising the binder compound according to  claim 1  in a quantity of 1 to 20 w. %, more specifically in a quantity of 10 to 15 w. %, more specifically in a quantity of 1 to 10 w. %, even more specifically in a quantity of 1 to 7 w. %, and an aggregate. 
     
     
         7 . Aqueous emulsion comprising the binder compound according to  claim 1  in a quantity of 40 to 70 w. %, water in a quantity of 60 to 30 w. % and an emulsifier in a quantity of 3 to 10 w. %. 
     
     
         8 . Cold adhesive compound comprising
 the binder compound according to  claim 1  in a quantity of 25 to 70 w. %, more specifically a quantity of 40 to 50 w. %; and   one or more solvents or vegetable oils or derivatives of vegetable oils or a combination thereof in a quantity of 7 to 25 w. %; and   a filler in a quantity of 25 to 30 w. %.
