Abstract
Abstract A mixture of waste, essentially cellulosic material and a fire proofing solution can be used to make building materials with exceptional qualities. These qualities include fire proofing, vermin proofing, water proofing and excellent insulative values, for example. Additionally, this process represents an excellent method for recycle of these waste materials. A sheetrock-like or wall-board material can be made therefrom, one which can be nailed, screwed, drilled and fastened without causing serious damage to the surface or the element itself.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
180 words
A mixture suitable for use in the manufacture of building materials comprising, based on 100 total parts by weight of the mixture, an admixture of 80 to 40 parts by weight of waste material consisting essentially of cellulosic waste and 20 to 60 parts by weight of an equal mixture of the following two parts solution: Part A, the first part comprising a mixture of three liquid silicates of varying viscosities with the following composition: (a) 50% by weight of a solution of about 8.9% Na 2 O and about 28.7% SiO 2 and having a specific gravity of between 35°-40° Baume; (b) 25% by weight of a solution of about 11.0% Na 2 O and about 31.7% SiO 2 and having a specific gravity of between 40°-50° Baume; and (c) 25% by weight of a solution of about 8.3% K 2 O and about 20.8% SiO 2 and having a specific gravity of between 65°-85° Baume; and Part B, the second part comprising an aqueous mixture of equal amounts of acetic acid, borax, kaolin, zinc oxide and sodium bicarbonate.

Claim 3
Dependent Claim
79 words
The mixture according to claim 1 wherein 60 parts by weight of said waste material is mixed with 40 parts by weight of said two part solution, wherein the ingredients of said two part solution are present in the following amounts by weight: Part A: (a) 24 oz; (b) 12 oz; and; (c) 12 oz; and Part B comprises 2 oz. each of acetic acid, borax, kaolin, zinc oxide and sodium bicarbonate dissolved in water to make 48 oz.
Claim 4
Dependent Claim
199 words
A process for the manufacture of wall-board comprising making a mixture of 60 parts waste, cellulosic material and 40 parts of an equal mixture of the following two part solution: Part A: (a) 50% by weight of a solution of about 8.9% Na 2 O and about 28.7% SiO 2 and having a specific gravity of between 35°-40° Baume; (b) 25% by weight of a solution of about 11.0% Na 2 O and about 31.7% SiO 2 and having a specific gravity of between 40°-50° Baume; and, (c) 25% by weight of a solution of about 8.3% K 2 O and about 20.8% SiO 2 and having a specific gravity of between 65°-85° Baume; and Part B, the second part, comprising an aqueous mixture of equal amounts of acetic acid, borax, kaolin, zinc oxide and sodium bicarbonate, and coating said mixture of solutions and waste material to one surface of a sheet of cardboard, applying a second sheet of cardboard over said coating to obtain an element comprising a sandwich of mixture coated between cardboard sheets, pressing said sandwich at 50 to 120 psi for about 30 seconds, followed by curing said sandwich at about 100° to 150° F.
Claim 5
Dependent Claim
199 words
A process for the manufacture of wall-board comprising making a mixture of 60 parts waste, cellulosic material and 40 parts of an equal mixture of the following two part solution: Part A: (a) 50% by weight of a solution of about 8.9% Na 2 O and about 28.7% SiO 2 and having a specific gravity of between 35°-40° Baume; (b) 25% by weight of a solution of about 11.0% Na 2 O and about 31.7% SiO 2 and having a specific gravity of between 40°-50° Baume; and, (c) 25% by weight of a solution of about 8.3% K 2 O and about 20.8% SiO 2 and having a specific gravity of between 65°-85° Baume; and Part B, the second part, comprising an aqueous mixture of equal amounts of acetic acid, borax, kaolin, zinc oxide and sodium bicarbonate, and coating said mixture of solutions and waste material to one surface of a sheet of cardboard, applying a second sheet of cardboard over said coating to obtain an element comprising a sandwich of mixture coated between cardboard sheets, pressing said sandwich at 50 to 120 psi for about 30 seconds, followed by curing said sandwich at about 100° to 150° F.
