Method of applying an insulating element by adhesive bonding

Abstract

A method of applying an insulating element by adhesive bonding in a waterproofing system, where at least the insulating element or the support on which it is applied is porous, the insulating element being bonded by means of an adhesive based on a bituminous emulsion having a maximum water content of 35% and containing a bitumen whose penetration is between 20 and 300 dmm.

1 - 10 . (canceled)  
   
   
       11 . A method of applying an insulating element in a waterproofing system, by adhesive bonding, comprising applying an adhesive composition to a support element and applying the insulating element thereto, wherein at least one of the support element and the insulating element is porous, and wherein the adhesive composition is a bituminous emulsion adhesive composition comprising: 
 (a) up to 35% by weight water;    (b) a bitumen having a penetration value of about 20 to about 300 dnm; and    (c) an emulsifier.    
   
   
       12 . The method according to  claim 11  wherein the bituminous emulsion adhesive composition further includes up to about 10% by weight of a thickening agent in the water phase.  
   
   
       13 . The method according to  claim 11  wherein the bituminous emulsion adhesive composition further includes up to about 25% by weight of a filler.  
   
   
       14 . The method according to  claim 11  wherein the emulsifier is an anionic emulsifier.  
   
   
       15 . The method according to  claim 11  wherein the emulsifier is a non-ionic emulsifier.  
   
   
       16 . The method according to  claim 11  wherein the adhesive composition comprises up to about 35% by weight water, about 40% to about 70% by weight bitumen, about 10 to about 30 kg/tonne emulsifier, about 2% to about 5% by weight of a thickening agent, and up to about 20% by weight of a filler.  
   
   
       17 . The method according to  claim 16  wherein the adhesive composition further includes an elastomeric polymer.  
   
   
       18 . The method according to  claim 16  wherein the adhesive composition has a viscosity of about 5 to about 400 Pa.s.  
   
   
       19 . The method according to  claim 11  wherein the adhesive composition is applied to the support element in spots.  
   
   
       20 . The method according to  claim 11  wherein the adhesive composition is applied to the support element in lines.  
   
   
       21 . The method according to  claim 16  wherein the adhesive composition is dried for about 72 hours at about 20° C. to achieve at least 70% of maximum tear resistance for the waterproofing system.
