Abstract

A waterproof sheet structure for a cool roof includes a waterproof sheet layer and a top reinforce layer placed on one side of the waterproof layer. The top reinforce layer is impregnated in a liquid polymer and then dried, and is treated to have a light color. The liquid polymer has fire retardant property. The top reinforce layer is made of a fiberglass cloth, which includes a plurality of glass fibers woven with one another. The polymer fill gaps between the woven fibers. The polymer is impregnated onto the fiberglass cloth in such a thickness so that there are no glass fibers exposed out of the polymer. The waterproof sheet is made by forming the fiberglass cloth, and then coating asphalt on the fiberglass cloth with a constant thickness.

Claims

exact text as granted — not AI-modified
1 . A waterproof sheet structure for a cool roof comprising: 
 a) a waterproof sheet layer; and    b) a top reinforce layer placed on one side of the waterproof layer;    wherein the top reinforce layer is impregnated in a liquid polymer and then dried, and is treated to have a light color.    
   
   
       2 . The waterproof sheet structure according to  claim 1 , wherein the waterproof sheet layer comprises an asphalt sheet.  
   
   
       3 . The waterproof sheet structure according to  claim 1 , wherein the asphalt sheet has a thickness in a range from about one (1) to about five (5) mm.  
   
   
       4 . The waterproof sheet structure according to  claim 3 , wherein the asphalt sheet has a thickness in a range from about one half (1.5) to about three (3) mm.  
   
   
       6 . The waterproof sheet structure according to  claim 1 , wherein the liquid polymer has fire retardant property.  
   
   
       7 . The waterproof sheet structure according to  claim 1 , wherein the top reinforce layer comprises a fiberglass cloth.  
   
   
       8 . The joint sealing structure according to  claim 7 , wherein the fiberglass cloth comprises a plurality of glass fibers woven with one another, and wherein the polymer fill gaps between the woven fibers.  
   
   
       9 . The joint sealing structure according to  claim 8 , wherein the polymer is impregnated onto the fiberglass cloth in such a thickness so that there are no glass fibers exposed out of the polymer.  
   
   
       10 . The joint sealing structure according to  claim 7 , wherein each of the waterproof sheets is made by forming the fiberglass cloth, and then coating asphalt on the fiberglass cloth with a constant thickness.  
   
   
       11 . The waterproof sheet structure according to  claim 7 , wherein the fiber glass cloth is soaked in the liquid polymer, and then dried at a temperature in a range from about 100 to about 150 degree Celsius.  
   
   
       12 . The waterproof sheet structure according to  claim 11 , wherein the fiber glass cloth is dried for a time period in a range from about 3 to about 5 minutes.  
   
   
       13 . The waterproof sheet structure according to  claim 7 , wherein the fiberglass cloth has a thickness in a range from about 0.1 to about 0.3 mm.  
   
   
       14 . The waterproof sheet structure according to  claim 1 , further comprising a base layer placed on the other side of the waterproof layer.  
   
   
       15 . The waterproof sheet structure according to  claim 14 , wherein the top reinforce layer is laminated on one side of the waterproof sheet layer, and wherein the base layer is laminated on the other side of the waterproof layer.  
   
   
       16 . The waterproof sheet structure according to  claim 14 , wherein the base layer comprises a fiber non-woven fabric.  
   
   
       17 . The waterproof sheet structure according to  claim 14 , wherein the base layer comprises a fine sand layer.  
   
   
       18 . The waterproof sheet structure according to  claim 14 , wherein the base layer comprises a polyester film.  
   
   
       19 . The waterproof sheet structure according to  claim 1 , wherein the liquid polymer is selected from the group consisting of acrylic resin, epoxy resin, polyurea resin, and polyurethane.
