MANUFACTURE FIBER BOARD.

The invention relates to improvements in the manufacture of fiber board, and particularly to a fiber board which is especially adapted for use in the manufacture of printedsigns. I
The object of the inventlon 1s to produce a fiber board, suitable for the manufacture.

palmitic acids, the same permitted to distimatelv associated with the fibers in the beater charge.
Then are added the salts of some metals which form insoluble soaps of the or auic A fiber board, made according to the proc- 4 such an oil phase and which are readily wetted by Water. i
Furthermore the printing surface of the treated board is smoother and freer from irregularities, thereby allowing the ink printed upon it tolcover the surface more smoothly and to lie smoother than on 'ordi:
nary board. i
The essential step in this invention is to coat the fibers of a piece of board, with an .insoluble metal soap, thereby rotecting the fibers and making the boar waterproof, excellent to print, smooth after calendering, and upon which the rinted surface will be smooth and free fiiom irregularities, as above stated.
The problem-ofgetting the insoluble soap into the fiber may be solved in two ways, but preferably is done in the beating engine, when the aper is in the aqueous pulp stage. It may a so be accomplished by treatment of the formed paper sheet, although this is more difiicult and will probably require special apparatus in large commercial practice. Since each fiber must be coated with the material, to fully waterproof a web of paper, the process involves the chemical formation of the insoluble metal salt in the presence of the fibers.
The preferred process is carried out by adding to the beater, haviuga charge of paper stock and water therein, a solubleof said metals.
acids employed in the first step, in su cient quantity to re-act with all of the soluble solve in the beater water so as to be insoaps, and, effect complete 'preci itation thereof, in the form of the insolub e soaps Thus in the specific process, of which the first step has been stated, there is formed and added to the beater a solution of the soluble salts of alumina, barium, lead, zinc,
or other metals of the insoluble organic soapgroup suflicient to effect complete precipitation, so that the total quantity of metallic soaps produced will amount to from one to it is desired to produce.
three per cent of the weight of theboard that One salt which has shown superior results in the process is lead acetate, which can easily be brought to solution in water, and 1s inexpensive.
The result of the precipitation of insoluble soap in the presence of the'fiber, is that the. individual fibers become coated with the same, and as the usual steps in the manu- 't'acture of paper are proceeded with, the resultlng sheet will have its fibers thoroughly coated, and will exhibit the qualities above tion, and gain a thorough saturation of each fiber, it may be a vacuu'm.-
The saturated web is next treated with a solution of the metal salt, and again is necessary to use pressureor thoroughly saturated, if necessary with pressure or vacuum, so as to gain a complete reaction. resulting as before in the preclpltaiiou of the insoluble soaps;
Finally, if necessary, the sodium salts left by the reaction, may be washed out of the web. by any desired method which will not disintegrate the web. and the web may then be calcndercd' and dried.
For weatherproof signs, to be exposed to the elements-over longperiods of time, the board produced by my process is excellent,
' and the improved printing surface it affords,
insures longer life for the printed design upon it.
T1 '5 process 5 iould be distinguished from a sizing process, as it proceeds further than sizing, to the extent of the precipitation upon the-fibers of an insoluble body in dispersed or colloidal form.
Having thus described the process, What is claimed as new and desired to be secured by Letters Patent, is
The process of manufacturing weather resistant fiber board, whichconsists in thoroughly mixing fiber pulp in an aqueous solution of soap and treating the pulp with lead acetate to precipitate insoluble lead soap in intimate admixture with said fiber, the quantity of soap required being sufficicnt to provide approximately not over three per cent by Weight of insoluble soap on the basis of the pulp use-d.
