Patented June 5, 1934 MANUFACTURE OF MULTI-PLY PAPER BOARD De Witt 0. Jones and George G. Krug, South Milwaukee, Wis., assignors to E. L du Pont de Nemours & Company, Wilmington, Del., a corporation of Delaware No Drawing. Application November 2, 1931,
Serial No. 572,722
1': Claims. (Cl. 154-40) This invention relates to the manufacture of multi-ply paper board in which a'sizedand water resisting paper liner is used. The invention resides more particularly in the use of silicate adhesives with sized papers, specifically the rosin sized papers of the Fourdrinier type, which contains the size evenly distributed therethrough, rendering the entire paper very resistant to moisture. 10 Silicate adhesives have been used almost exclusively in the manufacture of both the corrugated paper and solid fiber boards, and have proved the most desirable adhesive when the liners for the board are made from unsized paper 16 stock or where they are sized only on one side.
With the introduction into the paper board manufacture of the sized paper of the Fourdrinier type, which is now fast supplanting the other types of liners because of its strength, cost, and 20 water resisting properties, difliculty has been experienced with the use of the silicate adhesives.
When used on the paper board machines, it was found that the silicate adhesives would not set quickly enough to form a firm bond between the water resisting liner and the filler in the interval of time after the application of the adhesive and before the board passed through the cutters. The cutter would disrupt the bond at a time when the silicate was still wet, yet when it had reached a stage where re-adhesion would not take place.
Various concentrations of silicate were tried, as well as the different kindsof silicates, but only by slowing down the machines to a point where it was commercially impractical could the silicate adhesives be used. In order to get the speed necessary for commercial production, the man- 'ufacturers were then forced to revert to the use of glues. 4c Silicate adhesives-are much more desirable than glues in this particular art, where most of this type of paper board is used in making shipping containers, for the reason that the silicate adhesives are odorless, vermin proof, not subject to decay, more resistant to fire, and are cheaper.
It is known that the silicate, when used as an adhesive, functions by losing a certain amount of water. Penetration of the one surface to which the adhesive is applied is not suflicient. When .used in the pasting machines, sufficient water "must be abstracted from the silicate between the time of its application and when that part reaches the cutter, so that the bond is firm enough to resist the slight strain on the partially cemented layers that are being cut. Where the liner and filler are both unsized paper, the absorption of the water from the adhesive is rapid from both sides of the silicate film. Where the liner is of sized stock and not water absorbent, there is difficulty experienced.
We find that by depositing in the surface of the sized paper liner to which the silicate is to be applied a substance which will aid the sized pa-' per in taking up some of the moisture from the adhesive film or render the fibers of the paper on that surface water absorbent, the silicate will then dry sufliciently fast to permit'its use on the paper board machines.
Wetting agents such as the alkali metal salts of alkylated naphthalene sulfonic acids and soluble rosin soaps, which, when dried will readily absorb moisture and also cause the silicate to wet the paper rapidly, have been found to give the desired result when deposited and dried on the surface of 'the paper. Alkaline substances which will react with the rosin size in the paperto make the rosin size soluble also give the desired result. The alkaline materials, however, unless very carefully used, are apt to weaken the paper structure and usually tend to discolor it, due tothe. chemical action so which takes place. r
We have found that by applying a very dilute solution of the sodium salt of isopropyl naphthalene sulfonic acids to the side of the paper to be pasted, and then permitting it to dry on the paper, the 35 silicate adhesive, when later applied, readily penetrates the surface and dries rapidly, effecting the desired bond within the time necessary for it to be used on the paper board machines. Solutions as low as .015% up to .5% of the sodium salt of naphthalene sulfonic acids are suflicient when the one surface of the paper is only slightly moistened with such solution. More concentrated solutions may be used, but are not necessary, and add materially to the cost of the treatment. 5
The wetting and water absorbing material is preferably applied at the time the paper is made, although it may be applied at any later time. Drying of the wetting agent on the paper liner prior to-the application of the silicate is preferred so that more rapid absorption of the water from the silicate will take place, for a slight excess of moisture in the paper at the time the silicate is used retards its time of setting;
The amount of the wetting and absorbing agent applied to the paper should be, preferably, only enough to penetrate the surface so that the ,size in the body of the paper will not be affected and will retain its water resisting property.
- While we have mentioned particularly the alkyl naphthalene sulfonic acids and soluble rosin soaps, our invention is not limited thereto, for the use of any wetting agent which may be deposited in the surface of the liners, which is preferably nonvolatile, and which will aid in the absorption of the water from the silicate adhesive when it is applied, comes within the purview of our invention. The more volatile wetting agents such as the aromatic and terpinic alcohols, when applied to the paper just prior to the application of the silicate, will effect a wetting of the fibers, but due to the added moisture at that time do not give as good results as those which are present in a state in which they aid in abstracting moisture from the silicate, and are, therefore, not as desirable as those compounds which may be left in the paper fiber in substantially dry form.
' As further examples of the wetting agents we have found to be useful, may be mentioned butylnaphthalene sulfonic acid, Turkey red oil, the condensation product of formaldehyde and naphthalene sulfonic acids, abietene sulfonic acids, or a mixture of abietene sulfonic acid and terpineolas disclosed in application Ser. No. 415,789, of Clyde 0. Henke, filed December 12, 1929. These compounds may be used in acid, alkaline or neutral solution.
