Process for making a product of artificial rock and a product thus made

Abstract

The present invention relates to a process for making a product of artificial rock and a product thus made for use, in particular, in aquariums, tanks, swimming pools and the like; the process comprises the following operating steps: carrying out a first deposition of a mixture of powdered aggregates, resin, additives, within a cast or mould; catalyzing the mixture of said first deposition; covering the surface thus obtained with isophtalic or bisphenolic polyester resin; carrying out a second deposition of powdered aggregates, resin, additives; covering the surface derived from the second deposition with a layer of structural component and with resin; polymerizing the intermediate product thus obtained; covering the surface thus obtained with a layer of gel; polymerizing the product thus obtained; removing the product from the mould; subjecting the product to a heating treatment.

1 . A product defining an artificial rock, to be used, in particular, for aquariums, tanks, swimming pools and the like, product that consists of a mixture of aggregates, isophtalic or bisphenolic polyester resin and additives.  
   
   
       2 . Product according to  claim 1 , wherein the granulometry of the aggregates is variable and their thickness is less than 5 mm in diameter.  
   
   
       3 . Product according to  claim 2 , wherein the granulometry of the aggregates is variable and their diameter is less than 2 mm.  
   
   
       4 . Product according to  claim 1 , wherein the additives comprise a thickener, structural glass fiber and various aggregates.  
   
   
       5 . Product according to  claim 1 , wherein it is made up of two overlapping layers of said polymerized mixture, covered with two successive layers of glass fiber and resin.
