Two scrim laminate

Abstract

The present invention provides a drain-through type of designed portable work and walking surface matting, which has the size, weight and slip resistant characteristics, as well as the anti-fatigue properties which make it a more desirable surface on which to walk and work. The invention consists of the lamination of two dimensionally stable or unstable coated scrims to produce a dimensionally stable laminate. Each coated scrim has a plurality of openings extending through the scrim. The lower surface of the first coated scrim is permanently bonded to the upper surface of the second coated scrim.

We claim:  
     
         1 . A laminate construction, comprising: 
 a first scrim having an open area;    a first coating applied to the first scrim to form first coated scrim having an upper surface, a lower surface, and an open area ranging from 2% to 80%;    a second scrim having an open area to form a second coated scrim having an upper surface, a lower surface, and an open area ranging from 2% to 80%;    a second coating applied to the second scrim; and    an adhesive applied to one of the lower surfaces of the first coat and scrim, and the upper surface of the second coat and scrim, whereby the first coated scrim and the second coated scrim are bonded together to form a two scrim laminate.    
     
     
         2 . The laminate construction of  claim 1  wherein the first coated scrim has an open area ranging from 2% to 20%.  
     
     
         3 . The laminate construction of  claim 1  wherein the second coated scrim has an open area ranging from 25% to 45%.  
     
     
         4 . The laminate construction of  claim 2  wherein the second coated scrim has an open area ranging from 25% to 45%.  
     
     
         5 . The laminate construction of  claim 1  wherein the first scrim is a polyester.  
     
     
         6 . The laminate construction of  claim 5  wherein the first scrim is a knitted polyester.  
     
     
         7 . The laminate construction of  claim 6  wherein the first coating is a formed PVC plastisol.  
     
     
         8 . The laminate construction of  claim 1  wherein the second scrim is a polyester.  
     
     
         9 . The laminate construction of  claim 8  wherein the second scrim is a knitted polyester.  
     
     
         10 . The laminate construction of  claim 9  wherein the second coating is an unfoamed PVC plastisol.  
     
     
         11 . The laminate construction of  claim 7  wherein the second scrim is polyester.  
     
     
         12 . The laminate construction of  claim 11  wherein the second scrim is a knitted polyester.  
     
     
         13 . The laminate construction of  claim 12  wherein the second coating is an unfoamed PVC plastisol.  
     
     
         14 . The laminate construction of  claim 1  wherein the first srim is selected from the group consisting of polyester, polypropylene and jute.  
     
     
         15 . The laminate construction of  claim 1  wherein the first coating is selected from the group consisting of PVC plastisol, latex, polyurethanes, acrylics and thermoplastic elastomers.  
     
     
         16 . The laminate construction of  claim 1  wherein the second scrim is selected from the group consisting of polyester, polypropylene and jute.  
     
     
         17 . The laminate construction of  claim 1  wherein the second coating is selected from the group consisting of PVC plastisol, latex, polyurethanes, acrylics and thermoplastic clastomers.  
     
     
         18 . The laminate construction of  claim 1  wherein the adhesive is a two component polyurea adhesive.  
     
     
         19 . The laminate construction of  claim 13  wherein the adhesive is a two component polyurea adhesive.  
     
     
         20 . The laminate construction of  claim 1  wherein the adhesive is selected from the group consisting of two component polyurea adhesives, solvent based nitrile, adhesive, one component moisture cure urethane adhesives, acrylics and vinyls.
