Surface Adhesives for Building Boards

Abstract

The present disclosure relates to performance enhancing surface coatings for building boards. More particularly, the disclosure relates to the using of building boards employing surface adhesives to eliminate the need for fasteners in holding building boards in place after installation.

What is claimed is: 
     
         1 . A building board construction comprising:
 a gypsum panel including interior and exterior surfaces and a set gypsum core, the exterior surface including a dense gypsum layer that includes a reactive polymer material;   an adhesive layer having interior and exterior surfaces and a thickness within the range of about 0.01 mils to about 500 mils, the interior surface of the adhesive layer secured to dense gypsum layer, the adhesive layer including a thermoplastic material that reacts with the polymer material within the dense gypsum layer, whereby a polymer matrix is formed once the adhesive layer is secured to the dense gypsum layer;   a series of decorative tiles secured to the exterior surface of the adhesive layer.   
     
     
         2 . The building board construction as described in  claim 1  wherein the thermoplastic material comprises Acrylonitrile butadiene styrene (ABS). 
     
     
         3 . The building board construction as described in  claim 1  wherein the thermoplastic material comprises Ethylene Vinyl Acetate (EVA). 
     
     
         4 . The building board construction as described in  claim 1  wherein the melting point of the adhesive layer is between about 100 degrees Fahrenheit to about 500 degrees Fahrenheit. 
     
     
         5 . The building board as described in  claim 1  wherein the adhesive layer is applied via a roller coater immediately following the initial set of the gypsum panel. 
     
     
         6 . A building construction comprising:
 a building panel including interior and exterior surfaces, the interior surface including a polymer material;   an adhesive layer secured to the interior surface of the building panel, the adhesive layer including a thermoplastic material that is reactive with the polymer material within the interior surface of the building panel, whereby a polymer matrix is formed between the adhesive layer and the interior surface;   a building framing member, the adhesive layer functioning the secure the building panel to the framing member.   
     
     
         7 . The building construction as described in  claim 6  wherein the adhesive layer includes a release liner. 
     
     
         8 . The building construction as described in  claim 6  wherein the building panel is formed from hydraulic cement. 
     
     
         9 . The building construction as described in  claim 6  wherein the building panel is formed from a magnesium based cement. 
     
     
         10 . The building board construction as described in  claim 6  wherein the thermoplastic material comprises Acrylonitrile butadiene styrene (ABS). 
     
     
         11 . The building board construction as described in  claim 6  wherein the thermoplastic material comprises Ethylene Vinyl Acetate (EVA). 
     
     
         12 . The building board construction as described in  claim 6  wherein the melting point of the adhesive layer is between about 100 degrees Fahrenheit to about 500 degrees Fahrenheit. 
     
     
         13 . A building board construction comprising:
 a composite building panel including interior and exterior surfaces;   a pressure sensitive adhesive layer applied to one of the surfaces of the composite building panel, the adhesive layer including a thermoplastic material.   
     
     
         14 . The building board construction as described in  claim 13  wherein the composite building panel includes a fibrous mat on one of the surfaces and wherein the pressure sensitive adhesive is applied to the fibrous mat. 
     
     
         15 . The building board construction as described in  claim 13  wherein the composite building panel includes a paper face on one of the surfaces and wherein the pressure sensitive adhesive is applied to paper face.
