Decorated fireproof building substrate

Abstract

A decorated fireproof building substrate includes a fireproof building substrate and a decorated multilayer. The fireproof building substrate includes a substrate and a fireproof layer, wherein the fireproof layer covers the surface of the substrate. The decorated multilayer includes an adhesive layer, a printed layer, a grain layer and a hard coating layer disposed on the fireproof building substrate subsequently. The hard coating layer is located at the outermost side of the decorated multilayer, wherein the grain layer also can has the function of the hard coating layer so as to omit the disposal of the hard coating layer.

What is claimed is: 
     
         1 . A decorated fireproof building substrate, comprising:
 a fireproof building substrate, comprising a substrate and a fireproof layer, wherein the fireproof layer covers a surface of the substrate; and   a decorated multilayer, comprising a printed layer, a grain layer, and a hard coating layer disposed on the fireproof building substrate subsequently, wherein the hard coating layer is located at the outermost side of the decorated multilayer.   
     
     
         2 . The decorated fireproof building substrate as claimed in  claim 1 , wherein the decorated multilayer further comprises an adhesive layer, and the adhesive layer adheres between the fireproof layer and the printed layer. 
     
     
         3 . The decorated fireproof building substrate as claimed in  claim 1 , wherein the surface of the substrate has a plurality of pores, and the fireproof layer at least fills the pores. 
     
     
         4 . The decorated fireproof building substrate as claimed in  claim 1 , wherein the printed layer, the grain layer, or the hard coating layer are further added with a fireproof material. 
     
     
         5 . The decorated fireproof building substrate as claimed in  claim 1 , wherein the grain layer has a planar surface relatively far from the fireproof layer and a patterned surface relatively close to the fireproof layer, and the patterned surface has a texture structure thereon. 
     
     
         6 . The decorated fireproof building substrate as claimed in  claim 5 , wherein the printed layer has another patterned surface, and the patterned surface of the printed layer and the patterned surface of the grain layer are adhered to each other, such that the patterned surface of the printed layer has the texture structure thereon. 
     
     
         7 . The decorated fireproof building substrate as claimed in  claim 1 , wherein an outer surface of the hard coating layer has a texture structure thereon.
