Thin glass/metal laminate with anti-glare surface

Abstract

Disclosed herein are laminated structures comprising a metal sheet including a first face and a second face with a thickness of from about 0.5 mm to about 2 mm extending between the first face and the second face. The laminated structure further includes a first chemically strengthened or non-chemically strengthened glass sheet including a thickness of less than or equal to about 2 mm and a first interlayer attaching the first glass sheet to the first face of the metal sheet. Also disclosed herein are methods of manufacturing a laminated structure comprising the steps of laminating a metal sheet and a first glass sheet together with an interlayer.

         2 . The laminated structure of  claim 1 , wherein the first interlayer comprises a layer of polyvinyl butyral or an ionomer. 
     
     
         3 . The laminated structure of  claim 2 , wherein the layer of polyvinyl butyral has a thickness ranging from about 0.1 mm to about 0.8 mm. 
     
     
         4 . The laminated structure of  claim 2 , wherein the layer of ionomer has a thickness ranging from about 0.1 mm to about 2 mm. 
     
     
         5 . The laminated structure of  claim 1 , wherein the first glass sheet comprises a glass or glass ceramic containing silver, copper or a combination of silver and copper or comprises a glass or glass ceramic having a coating thereon, said coating containing silver, copper or a combination of silver and copper. 
     
     
         6 . The laminated structure of  claim 1 , wherein the Young's modulus of the first interlayer is greater than or equal to 15 MPa. 
     
     
         7 . The laminated structure of  claim 6 , wherein the Young's modulus of the first interlayer is greater than or equal to 275 MPa. 
     
     
         8 . The laminated structure of  claim 1 , wherein the first glass sheet comprises an acid-etched glass sheet. 
     
     
         9 . The laminated structure of  claim 1 , wherein the first glass sheet has a thickness ranging from about 0.5 mm to about 1.1 mm. 
     
     
         10 . The laminated structure of  claim 1 , wherein the first glass sheet is chemically strengthened and comprises a glass selected from the group consisting of aluminosilicate glass and alkali-aluminoborosilicate glass. 
     
     
         11 . The laminated structure of  claim 1 , wherein the first glass sheet comprises at least one anti-glare surface and/or at least one anti-microbial surface. 
     
     
         12 . The laminated structure of  claim 1 , further comprising:
 a second glass sheet including a thickness of less than or equal to about 2 mm; and   a second interlayer attaching the second glass sheet to the second face of the metal sheet,   wherein the second glass sheet is chemically strengthened.   
     
     
         13 . A method of manufacturing a laminated structure comprising:
 (i) providing a metal sheet including a first face and a second face with a thickness ranging from about 0.1 mm to about 5 mm extending between the first face and the second face;   (ii) providing a chemically strengthened or non-chemically strengthened glass sheet having a thickness of less than or equal to about 2 mm and at least one anti-glare surface;   (iii) attaching the glass sheet to the first face of the metal sheet with a first interlayer.   
     
     
         14 . The method of  claim 13 , wherein the glass sheet has a thickness ranging from about 0.3 mm to about 1 mm. 
     
     
         15 . The method of  claim 13 , wherein the glass sheet is chemically strengthened and is selected from the group consisting of aluminosilicate glass and alkali-aluminoborosilicate glass. 
     
     
         16 . The method of  claim 13 , further comprising the step of treating the glass sheet to produce the at least one anti-glare surface, wherein the treating step is chosen from acid etching, creamy etching, masked acid etching, sol gel processing, mechanical roughening, and combinations thereof. 
     
     
         17 . The method of  claim 13 , further comprising a step of further strengthening the glass sheet, wherein the further strengthening step is chosen from acid etching. 
     
     
         18 . A method of manufacturing a laminated structure comprising:
 (i) providing a metal sheet including a first face and a second face with a thickness of from about 0.1 mm to about 5 mm extending between the first face and the second face;   (ii) providing a glass sheet having a thickness of less than or equal to about 2 mm;   (iii) treating the glass sheet to produce at least one anti-glare surface;   (iv) optionally chemically strengthening the glass sheet;   (v) optionally acid etching the glass sheet; and   (vi) attaching the glass sheet to the first face of the metal sheet with a first interlayer.
