  • PREGUMMED HANGING MATERIAL Filed Sept. 6, 1945 Patented July 29, 1947 PREGUMMED HANGING MATERIAL ,Jordan V. Bauer, Elmwoody Park, and Rudolph A. Selner, Chicago, Ill., assignors, by mesne assignments, to Stein, Hall & Co., Inc., a corporation of New York Application September 6, 1943, Serial No. 501,408
  • This invention relates to pregummed hanging materials, more particularly wallpapers, poster papers, billboard papers, canvas wall coverings, thin wooden panels, or other types of hanging materials having .a dried coating of adhesive thereon which requires only moistening to be applied to a wall or other surface.
  • Lobdell Reissue Patent No. 10,430 described a wallpaper which is dry sized on its back and, according to the patent, may be hanged by moistening the sized surface and applying it to a wall.
  • the sizing used is said to be dextrine, glue, paste, or gums.
  • No Ipractical or suitable pregummed hanging paper ever resulted from the teaching of the Lobdell patent because the problem of making a pregummed hanging paper is not so simple that it may be done merely by adding .an ordinary type of sizing material or glue -to the back of the paper and drying it.
  • a pregummed hanging material, such as a pregummed wallpaper must have certain characteristics which cannot be obtained with an ordinary adhesive. Excellent pregummed hanging papers and other pregummed hanging materials have been made in accordance with the teaching of U. S. Patents 2,183,532 and 2,215,848 granted to Hans F. Bauer.
  • One of the objects of the present invention is to provide a new and improved pregummed hanging material in which the r-emoistening adhesive thereon is made from readily available raw materials.
  • Another object of the invention is to provide a new and improved preguimned hanging material in which the remoistening adhesive is derived from a cereal flour treated in a particular way, as more fully hereinafter described.
  • a further object of the invention is the preparation of new ⁇ and improved yadhesive materials.
  • the adhesive coating should remoisten readily when water is applied to the coated sheet butshould n-ot be of such a soluble nature ias to wash oi of the paper under normal conditions of handling.
  • the remoistened adhesive lm should be of a slippery, slow drying character so that when the moistened wallpaper is applied to the wall, it can be readily slid into the proper position to butt the edges and match the pattern.
  • the remoistened adhesive film must be sufciently slow drying that it will not set up to :a non-slippery condition in the time interval that normally elapses between remoistening the sheet and applying it to the wall.
  • the adhesive After the sheet has been applied to the wall, the adhesive must dry out without causing the sheet to pucker or wrinkle and give a rm bond on any surfaces to which hanging papers are normally applied.
  • the viscosity of the i'lnal product lies within the range specified herein. It is also desirable in order to obtain the necessary slow drying characteristics that the amylaceous content of the iiour be hydrolized to such an extent that a substantial amount of reducing sugars are formed.
  • the slow drying and non-curling characteristics of the adhesive may be further improved by the addition of various soluble salts or other materials which act as plasticizers.
  • Examples of such soluble salts and plasticizing material which can be eiectively used both to slow down the rate of drying and also reduce the tendency of the coated sheet to curl are sodium chloride, sodium formate, sodium nitrate, sodium lactate, urea, glycerine, glucose, invert sugar, etc.
  • the protein component of the iiour contributes greatly to the slippery characteristic desired in the adhesive. Furthermore, it appears to act as a desirable supplement to the reducing sugars formed during the conversion and the added plasticizing materials in reducing the curling tendencies of the dried coated sheet.
  • the degree of conversion be such that the final adhesive product shows a reducing sugar content of at least 5% on a dry basis calculated as dextrose, and a viscosity when diluted with water to bring the ratio of solids to water to 1 part of solids to 10 parts Water, between 15 centipoises and 750 centipoises at 75 F.
  • the method used to determine reducing sugars is the approximate volumetric method disclosed in Methods of Analysis of the Association of O ⁇ fficial Agricultural Chemists, third edition (1930) chapter XXXIV, sections 31, 32, 33, page 377.
  • Brookeld viscosity apparatus For the purpose of determining viscosities, the Brookeld viscosity apparatus was used.
  • the adhesive as applied to the paper or other base material contain not less than 1 part of water nor more than 5 parts of water per 1 part of solids.
  • the ratio of solids to water should preferably not be less than about 1 to 1 for an adhesive of this type if the proper degree of adhesiveness and slip characteristics is to be attained when the adhesive lm is remoistened.
  • the ratio of water to solids is greater than 5 to l, the amount of drying required in order to apply the adhesive properly to the paper or other material which is to be coated will normally be prohibitive.
  • the adhesive From the standpoint of convenience in applying the adhesive to the paper or other material, it is desinable that the adhesive have sufficient iluidity that it may be picked up and applied in a uniform film to the paper by means of the applicator rolls of the coating machine. At the same time, however, the adhesive must have sufcient viscosity that it will not soak into the paper and leave little or no effective adhesive iilm on the surface of the sheet. With this coni sideration in mind, it has been found desirable that the viscosity of the adhesive as applied to the paper be adjusted to somewhere within the range of 400 to 13,000 centipoises at 100 F. as determined by the Brookfield viscosity apparatus.
  • the converting enzymes used may be one or more of the commercially produced enzymes of the alpha or alpha and beta amylase types added to the iiour composition in the proper proportions to attain the specified degree of conversion, or if desired, advantage may be taken of the enzymes of this type which are naturally present in Wheat or rye iiours, particularly those milled from sprout damaged grain, and blending them with such proportions of iiour milled from sound grain that a nal iiour mixture having the proper amount of enzyme present will be obtained.
  • This latter procedure has the advantage of lower cost and furthermore offers a means of utilizing a substantial proportion of lours that are not suitable for most food purposes.
  • acids may be used instead of enzymes as a means of hydrolizing the iiour to the degree herein specified.
  • the use of enzymes is preferable because of the greater convenience in handling.
  • Example I This example illustrates the manner in which a remoistening adhesive suitable for the manufacture of prepasted wallpaper was prepared from a white rye flour milled from sprout damaged grain.
  • the rye flour used in this particular example had an enzyme activity of 2.41 units of alpha amylase as determined by the Kneen & Sandstedt method (Cereal Laboratory Methods, 4th ed., page 96 (1941) Seventy-seven and seven-tenth (77.7) pounds of the above-mentioned rye flour was dispersed in 100 pounds of water and heated in a steam jacketed mixing kettle to a temperature of F. The mixture was then held at this temperature for twenty minutes, during which time the enzyme present converted the mixture to a fluid consistency. At the end of this period the temperature was raised to F. and held at this point for ten minutes.
  • the adhesive 'disclosed in this example when diluted with water to bring the ratio of solids to water to 1 to 10, had a Brookfield viscosity of 16 centipoises at 75 F.
  • Example II At the end of this period, the temperature was raised to 190 F. and held at this point for ten minutes. Then 2.2 pounds of zinc sulphate was added and the mixture allowed to cool for use.
  • the resultant adhesive product tested 5.4% reducing sugars calculated as dextrose on a dry basis and had a Brookfield viscosity of 1600 centipoises at 100 F. When applied to wallpaper stock on the basis of a dry coating Weight of fourteen or sixteen pounds per ream, it gave an ⁇ effective prepasted hanging paper which when remoistened had the necessary slow drying and slip characteristics.
  • the resultant adhesive tested 14.0% reducing sugars calculated as dextrose on a dry basis and had a Brookeld viscosity of y1300 centipoises at 100 F. When diluted with water to bring the ratio of solids to water to 1 to 10, the viscosity as determined by the Brookfield viscosity apparatus was 25 centipoises at a temperature of 75 F. kThe adhesive was satisfactory for prepasted wallpaper and had the necessary slow drying and slip characteristics for this purpose.
  • Example IV Pounds The above pretreated rye flour 81.4 Urea 15.0 Sodium acetate 3.0
  • Amyliq N (a commercial enzyme manufactured by Wallerstein Company, Inc., New York .6
  • the finished adhesive as prepared above tested 12.3% Yreducing sugars calculated as dextrose on a dry basis and had a Brookfield viscosity of 1620 centipoises at 100 F. When diluted with water to bring the solids to water ratio to 1- to 10, it had a Brookfield viscosity of 40 centipoises at The adhesive thus prepared was slow drying on being remoistened and had excellent slip characteristics. G-ood results were obtained when dried coatings of the adhesive were formed on wallpaper in the preparation of pregummed hanging papers.
  • YExample V This example illustrates the manner in Which a wallpaper adhesive was prepared from a white rye our Vhaving an alpha amylase activity of ,40 unit and a malted wheat flour having an alpha amylase activity of 17.0 units as determined by theKneen and Sandstedt method, supra.
  • the ⁇ resultant adhesive tested 16.0% reducing Sugars calculated as dextrose on a dry basis.
  • the viscosity of the adhesive as determined by the Brookfield viscometer was 1400 centipoises at F. When diluted with water to bring the solids to Water ratio to 1 to l0, it had a Brookeld viscosity of 21 centipoises at 75 F.
  • cereal flour is employed herein to coverthe ours of cereal grains including, for example, wheat, oats, rye, rice, and barley. Those grains containing a substantial proportion of protein, and especially Wheat and rye, are particularly suited for the practice of the invention.
  • Hydrolized cereal flour is employed to cover a, cereal flour which has been degraded or converted in the wet with acids and/or enzymes.
  • enzyme hydrolized cereal flour is employed herein to cover hydrolized cereal flours which have been degraded or converted in the wet primarily ⁇ clue to th'e action of enzymes. In these enzyme conversions the pH may be adjusted and may be varied, depending upon the particular type of Hour, the amount of enzyme present, and the amount of conversion desired.
  • the enzyme may be a chemically isolated enzyme, as in Example IV, or more preferably is derived from a cereal flour having a predetermined minimum natural enzyme content, as for instance in Examples I and II, or from a blend of cereal nours, one of which has a relatively high enzyme content, as for instance in Example V.
  • the alph'a amylase content may be taken as a measure of enzyme activity in a cereal flour, and it is preferable for the purpose of the invention to employ a cereal flour or a blend of cereal flours having a predetermined alpha amylase content or a predetermined average alpha amylase content of at least 0.25 unit, as determined by the method of Kneen and Sandstedt, supra, preferably in excess of 0.4 unit.
  • the maximum enzyme content is not so critical because it can be compensated for by adjusting the pH and still obtain the desired predetermined viscosity.
  • the pH is preferably within the range of about 6.5 to '7. If the enzyme content were much' higher, it could be compensated for by adding an alkaline reacting substance to increase the pH and thereby reduce the enzyme activity.
  • plasticizer and plasticizing agent are used herein to cover any substance which, when incorporated with the adhesive, has the effect f slowing the rate of drying of the remoistened adh'esive coating and also tends to reduce the curling tendency of the dried adhesive coating When applied to a flexible base material, such as paper.
  • Any water soluble salt such as sodium chloride, sodium formate, sodium sulphate, sodium acetate, sodium nitrate, sodium thiocyanate, and the corresponding potassium, calcium, and magnesium salts which are soluble are effective to slow down the rate of drying of the remoistened adhesive and to some extent prevent curling.
  • plasticizing agents are more effective in reducing the tendency to curl, including for example, sodium lactate, urea, glycerine, glucose, invert sugar, and other hygroscopic substances. In many instances, therefore, it is preferable to employ a combination of plasticizing agents.
  • the reducing sugars formed by the hydrolization of the cereal flours also act as plasticizing agents and according to one method of practicing the invention a hydrolized cereal flour containing a large percentage of reducing sugars may be blended with a hydrolized cereal our containing a smaller percentage of reducing sugars.
  • a product such as that of Example II may be blended with one such as described in Example I.
  • the auxiliary plasticizing agent may be omitted or the amount of the auxiliary plasticizing agent may be substantially reduced.
  • the adhesives employed in accordance with the invention may be prepared in the form of dry base materials comprising a cereal flour containing a predetermined natural enzyme content, as previously defined, or a blend of a cereal flour with another cereal flour having a natural enzyme content sucient to produce said predetermined enzyme content or a cereal ilour with a chemically isolated enzyme added thereto, or blends of cereal flours with other amylaceous materials including starches, in combination with an auxiliary plasticizing agent of the type previously mentioned preferably in an amount equal to at least 5% by Weight of the total dry base and not greater than about 45% by weight.
  • the dry base containing the plasticizer is then h'ydrolized to form the adhesive in the manner previously described and the latter is applied to the back of a hanging material to form a dried coating thereon.
  • Bases of this type can also be used in making decalcomanias.
  • the specic type of adhesive base material employed not only gives a product of excellent adhesive characteristics for the purpose but also makes it possible to reduce, or in some cases, eliminate relatively expensive auxiliary plasticizing agents.
  • Another advantage of the invention is that the adhesives and pregummed hanging materials prepared therewith are derived from readily available raw material and, as previously indicated, good results have been obtained by using sprout damaged grain which cannot ordinarily be employed for foods. Other advantages will be apparent to those skilled in the art.
  • a pregummed hanging material comprising a base material having thereon a dried coating of an adhesive comprising as an adhesive base a hydrolyzed cereal flour having a reducing sugars content of at least 5% and not more than about 26% by weight of said dried coating calculated as dextrose, said adhesive coating when moistened possessing retack properties and slip characteristics permitting said material to slide While the adhesive is still Wet after it is rst applied to a surface.
