WILLIAM M. GROSvENOIt, OF NEW YORK, N. Y., ASSIGNOR TO PERKINS GLUE COMPANY,
A COMORATION OF PENNSYLVANIA.
VEGETABLE GLUE AND PROCESS OF MAKING THE SAME.
No Drawing.
. Specification of Letters Patent.
Application filed December 8, 1917, Serial No. 206,148. Renewed February 17, 1919.
Serial No. 277,645.
To all whom it may concern:
Be it known that I, WILLIAM M. GnosvnNoR, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Vegetable Glue and Procemes of Making the Same, of which the following is a specification.
My invention relates to improvements in vegetable glue and processes of making the same, the main objects being to produce a glue in which the water repellent quality is materially increased, so that joints made with the glue when dry are less likely to be affected by water or moisture, and, if desired at the same time, to render the glue more neutral while still retaining substantially the qualities of animal glue for gluing up veneers.
In U. S. Reissue Letters Patent, #13436, dated July 2, 1912, and in U. S. Letters Patent #1,020,656, 1,078,691, 1,078,692 and 1,200,488, there are disclosed methods of making vegetable glue by dissolving a starchy carbohydrate with a solvent of starch cellulose, such as caustic soda, the resulting glue being markedly alkaline. Even if the percentage of caustic alkali be reduced to about 3%, based on the dry Weight of the starch, and heat be used to aid the solution of the starch, the resulting glue is sufiiciently alkaline, so that when applied to very thin veneers of certain woods, it will cause a discoloration of the wood veneer, which discoloration. may appear disadvantageously on the opposite side of the wood layer from that on which the glue is applied; In many cases, this discoloration is not a serious disadvantage, but in other cases where very thin layers of fine wood are being glue together, this discoloration or staining may be a detriment which it is desirable to avoid.
While also the glue is more water repellent or water resistant when dry than animal glue, nevertheless, it is important to increase the water repellent quality of the glue as much as possible. In order that those skilled in the art may more clearly understand the invention, I will describe in detail several ways in which the invention may be carried out.
In producing the newglue, I take a suit able starchy carbohydrate, preferably the glue base degenerated or adjusted as to viscosity, in accordance with any of said U. S. Letters Patent. However, certain starches appear on the market which require no presoda solution added gradually with con-- tinu'al stirring and heat to 140 160 F. un-
til the batch is transformed from a mixture of suspended starch in water to a homogenous colloidal solution of starch, alkali and water, having substantially the adhesive and other properties of good animal glue for gluing up high grade Wood veneers as described in said Letters Patent. The resulting glue,a although thick and viscous, is capable of flowing through pipes 2 inches in diameter and of being spread by glue applying machinery, similar to animal glue.
After the starch has come across to produce the glue, as above described, and while still hot, I add thereto ordinary commercial rosin in the form of a fine powder, preferably so fine that it will pass through a one hundred mesh sieve. The rosin is added gradually and evenly, so as to be worked in throughout the glue. The amount of rosin required will depend on its quality, varying with what is known as the acid constant of the rosin. The addition is preferably con tinued until the glue is substantially neutral. The rosin reacts with the caustic of the glue to produce sodium resinate, which, upon the glue drying and being ex osed to the action of air, breaks up into rosin and sodium carbonate and bicarbonate, so that the rosin not only acts to neutralize the alkaline glue,
.IOSlIl are added in the form of a fine powder and thoroughly worked into the mass until it becomes completely emulsified. This emulsion is then added to the glue and thoroughly worked in as above described.-
However, due allowance in makin up the original glue should be made for t e water containedin this emulsion. In making up the emulsion, caustic soda or potash may be used cold, or carbonates may be used hot, instead of ammonia, but proportionately more of the emulsion is required to produce the same degree of neutrality.
If desired, substantially neutral ammonium resinate may be used in place of the rosin of the first example, to neutralize the glue. In such case, particularly when the glue is treated,'hot ammonia is expelled and breaks up in many cases,
a he caustic is reacted upon by the rosinproduced by the expelling of the ammonia from the resinate," to neutralize the caustic. In each of these cases the resinateformed to produce rosin as a water renellent material in the glue when dry. Other resins or resinous bodies which would tendto neutralize the particular alkaline solvent of cellulose used in making the glue maybe used in a similar manner.
If it is not important to provide any neufor the glue, as may happen other waxy bodies or water repellent materials may be used. Thus, for example, paraffin wax may be introduced by forming an emulsion of wax in water with a ve small amount of starch. For example, 22 5' parts by weight of water are mixed with 10 parts of starch and heated to a temperature preferably above 160 F. The mixture is either heated in or placed in a suitable emulsifier, and to this 'is added, either in the molten form or finel ground form, 15' parts of paraflin and t e whole thoroughly emulsified while being kept hot. The proportions of starch and paraflin may be considerabl decreased. or somewhat increased accord ng to the degree of water retralizing action sistance desired.
The emulsion kept between 130 and 140 F. preferably, not lower, is used instead ofthe water for dissolvin the starchy carbohydrate with the alka ine solvent of cellulose 'to form the glue. The starchy carbohydrate is preferably stirred into the parafiin emulsion while still warm, and the-temperature plete, w
nausea gradually raised as the 'caustic solution is added and then further raised to about 165% At about this temperature, the batch is continuousl agitated until bursting is comereupon it is allowed to cool, but the stirring is preferably discontinued be fore the temperature falls to that at which the wax begins to solidify. Care should be taken in usmg a starch of proper viscosity, as when this wax is used, a starch somewhat more degenerated should be used. than if rosin is used as the water'repellent agent, to produce a glue of the same final viscosity. Or the amount of water may be increased somewhat to accomplish the same end. Indeed, the water may be increased to substantially more than 3 parts, based on the dry weight of starch glue base depending upon the amount of paraffin and quality of the starch base. With certain waxes, a higher temperature is required to liquefy them and the boiling point of the water may be approached or exceeded, in which case it is best to use a closed emulsifier operating under pressure to-produce the emulsion.
Other water repellent materials may be used by incorporating them in the glue, either before or after the solution of the starch to form the glue has occurred, and whether or not such materials have the neutralizing action on the glue. Even when a reduced 'to a point where it is not considbe made absolutely neutral,
ered harmful for the particular class of wood in hand, and in some cases where the staining is unimportant the material added need have no efiect on the alkalinity of the glue. Likewise, if a nearly neutral glue is required and the question of water repellent quality 1s relatively unimportant, the resinous material added to neutralize need not iIiCIQaSG the water repellent quality of the g ue.
