Description

: Patented Apr. 15(1930 shall be fireproof and substantiall UNI-TED STA 1 as PATENT OFFICE EEBNANDO soIr aA-vIv-As, OF NEw ronxyN. Y., ASSIGNOR T0 INTERNATIONAL F RE- rEOoE- raopncrs GOBPOBA'IION, OF NEW Y RK, N. Y., A coRrORAa-ION or DELA- FIBEPBOOF wAL BQARD ANn'rnOOEss OE rnonUcINe THE sAME" 1T0 Drawing.
The invention relates'to wallboard which Waterproof and which may be produced .om any suitable cellulose material such as bagasse,-
wood pulp,- cornstalks, straw or the like.
It is an object of the invention to provide wallboard having the qualities named and which will be cheap to produce.
' It is a further object of the invention to provide wallboard of this character which shall have excellentsound and heat insulating qualities and at the same time shall be fireproof or exceedingly fire-resistant.
It is a further object of the invention to provide material of the character described which will be a suitable substitute for lum her in the construction of buildings.
Further objects of the invention will 'ap-. pear from the following description disclosing an illustrative embodiment of the invention.
The process of the invention may be carried out by preparing a pulp of any suitable cellu lose material such as bagasse, wood pulp or the like. In a desirable embodiment of the invention there is added to each pound. of the dried pulp one-half pound of calcium chloride dissolved in sufficient Water to provide a perfect saturation ofpulp without the water running from the pulp when it is han dled.
.After such a saturated 'pulp has been produced, there is added to the pulp a solution comprising resinated soap to the amo nt of one ounce to each pound of dried pii p producing in the pulp a calcium resinate soap I binder.
After thorough mixing of the soap solution with the pulp, the material is flowed with a strong solution of aluminum sulphate. A solution of suitable strength may be provided by'dissolving two ounds of sulphate in a I? desired, ammonia alum the soap binder already named will cause the same to be insoluble in water, and leave the pulp in condition to be pressed or rolled into shape as wallboard.
The thus treated pulp is formed into a sheet in any usual manner, the sheet when formed being desirably about one inch .in-
thickness after which it is pressedor rolled into the shape of wallboard to reduce its thickness to substantially three-fourths of an inch.
The compressed sheets are then dried to evaporate the water when the sheets will shrink to a thickness of practically one-half inch and the spaces in the sheet formerly occupied by. the water Will leave the sheet in a porous condition. y
The thus produced board is exceedingly fire-resistant, waterproof, cheap and easy to manufacture and is highlysound insulating and heat insulating. Plaster may be applied directly to such wallboard when inplace in buildings. In addition to its porosit and cheapness,
thewallboard is flexible an of light weight and forms an exceedingly desirable material for use inthe building. arts.
Minor changes may 7 position of thematerial or in the steps of the process of preparin the same, within. the
be made the comscope of the appended c aims without depart- A ing from the spirit of the invention.
I claim:
' -1. A wallboard comprising a porous body ofpellulose material impregnated with an,
insoluble calcium resinate soap binder.
2. A wallboard comprising a porous compressed body of cellulose material impregnated with a calcium resinate soap binder I'endered insoluble by treatment with an aluminum. sulphate.
3. The process of producing wallboard which comprises saturating a pulp of cellu-.
lose material with a solution of calcium chloride, adding resinated soap to the thus treated I pulp, treating the thus prepared material with a substance adapted to make the calcium soap binder insoluble and compressing the material into sheets. 'T
4. The process of producing wallboard which comprises-treating cellulose pulp with a solution of calcium chloride, treating the thus treated pulp with resinated soap, flowing the thus treated material with a solution of,
an alumiuum sulphate and forming thematerial into sheets. e 5. The process of producing wallboard which comprises saturating cellulose pulp with a calcium chloride solution, adding a, solution of a resinated soap to the thus prepared pulp, flqwing the thus treated material with a. strong s0lut10n of aluminum sulphate,
compressing the material into sheets and drying the sheets.
