Definitions

  • This invention relates to a process for the sizing of paper and to the improved paper thus prepared. More particularly, this invention relates to novel sizing agents for use in the sizing of paper and paperboard products.
  • a further object of this invention involves the use of sizing agents which may be employed with all types or" paper pulp over the complete range of pH conditions which are normally encountered in paper manufacturing.
  • An additional object involves the use of sizing agents which are fully compatable with alum and rosin as well as with the various fillers, pigments and other chemicals which may be added to paper.
  • paper and paperboard include sheet-like masses and molded products made from fibrous cellulosic materials which may be derived from both natural and synthetic sources. Also included are sheetdike masses and molded products prepared from combinations of cellulosic and non-cellulosic materials derived from synthetics such as polyamide, polyester and polyacrylic resin fibers as well as from mineral fibers such as asbestos and glass.
  • Paper and paperboard are often sized with various materials for the purpose of increasing their resistance to Water as well as to other types of aqueous solutions. These materials are referred to as sizes or sizing and they may be introduced during the actual paper making operation wherein the process is known as internal or engine sizing. Or, on the other hand, they may be applied to the surface of the finished web or sheet in which case the process is known as external or surface sizing.
  • wateruepellant materials have been utilized as sizing agents. These include rosin, mixtures oirosin with waxes, wax emulsions, ketene dimer emulsions, fluorocarbons, fatty acid complexes of chromium or "aluminum chlorides, long chain thermoplastic copolymers, @as well as some themnosetting condensation type resins. Although all of t ese materials are effective under certain conditions, their use is nonethless subject to one or more limitations.
  • rosin although the latter is relatively low in cost and readily available, it has poor resistance to alkaline solutions and cannot be used for the sizing of neutral or alkaline pulps. It is inoperable with the latter since it must be ordinarily used in combination with alum, or an acidic aluminum ion donor, which-is present for the purpose of precipitating and setting the sodium rosinate, i.e. the rosin soap, onto the fibers.
  • alum for this purpose is, however, precluded under neutral or alkaline conditions. This is a definite disadvantage since the paper produced from neutral and alkaline pulp has been found to have higher strength, greater stability and superior aging charv aliases Patented Aug.
  • a still further advantage of these sizing agents is that they do not detract from the strength of the paper and when used with certain adjuncts will in tact, increase the strength of the finished sheets.
  • An additional advantage of our novel sizing agents is that only mild drying or curing conditions are required to develop full sizing value.
  • novel sizing agents-of our invention may be described as substituted cyclic dicarboxylic acid anhydrides corresponding to the following structural formula:
  • R represents a :dimethylene or trimethylene radical and wherein R a hydrophobic group containing more than 5 carbon atoms which may be selected from the class consisting of alkyl, alkenyl, aralkvl or aralkenyl groups.
  • Substituted cyclic dicarboxylic acid anhydrides 3 falling within the above described formula are the substituted succinic and glutaric acid 'anhydrides.
  • sizing agents include iso-octadecenyl succinic acid anhydride, n-hexadecenyl s uccinic acid anhydride, dodecenyl succinic acid anhydride, dodecyl succinic acid anhydride, decenyl succinic acid anhydride, octenyl succinic acid anhydride, noneny-l succinic acid anhydride, triisobutenyl succinic acid anhydride, capryloxy succinic acid anhydride, heptyl glutaric acid anhydride, and benzyloxy succinic acid anhydride.
  • sizing agents of our invention Another important factor in the effective utilization of the sizing agents of our invention involves their use in conjunction with a material which is either cationic in nature or is, on the other hand, capable of ionizing or dissociating in such a manner as to produce one or more cations or other positively charged moieties.
  • cationic agents as they will be hereinafter referred to, have been found useful as a means for aiding in the retention of our sizing agents as Well as for bringing the latter into close proximity to the pulp fibers.
  • cationic agents include alum, aluminum chloride, long chain fatty amines, sodium aluminate, polyacrylamide, chromic sulfate, animal glue, cationic thermosetting resins and polyamide polymers.
  • cationic agents include various cationic starch derivatives including primary, secondary, tertiary or quaternary amine starch derivatives and other cationic nitrogen substituted starch derivatives, as well as cationic sulf-onium and phosphonium starch derivatives.
  • Such derivatives may be prepared from all types of starches including corn, tapioca, potato, waxy maize, wheat and rice. Moreover, they may be in their original granule form or they may be converted to pregelatinized, cold water soluble products.
  • any of the above noted cationic agents may be added to the stock, i.e. the pulp slurry, either prior to, along with or after the addition of the sizing agent. However, in order to achieve maximum distribution, it is preferable that the cationic agent be added either subsequent to or in direct combination with the sizing agent.
  • the actual addition to the stock of either the cationic agent or the sizing agent may take place at any point in the paper making process prior to the ultimate conversion of the wet pulp into a dry web or sheet.
  • our sizing agents may be added to the pulp while the latter is in the headbox, beater, hydropulper or stock chest.
  • our sizing agents be uniformly dispersed throughout the fiber slurry in as small a particle size as is possible to obtain.
  • non-cationic emulsifiers which may be used as emulsifying agents for our sizing agents, one may list such hydrocolloids as ordinary starches, noncationic starch derivatives, dextrines, carboxymethyl cellulose, gum arabic, gelatin and polyvinyl alcohol as well as various surfactants.
  • non-cationic emulsifiers it is often desirable to separately add a cationic agent to the pulp slurry after the addition to the latter of the emulsified sizing agent.
  • the sizing agent is then introduced along with vigorous agitation. If the sizing agent normally exists as a Waxy solid, it must first be melted prior to its emulsification.
  • the sizing agents of our invention may, of course, be successfully utilized for the sizing of paper prepared from all types of both cellulosic and combinations of cellulosic with non-cellulosic fibers.
  • the cellulosic fibers which may be used include bleached and unbleached sulfate (kraft), bleached and unbleached sulfite, bleached and unbleached soda, neutral sulfite, semi-chemical, chemigroundwood, ground wood, and any combination of these fibers. These designations refer to wood pulp fibers which have been prepared by means of a variety of processes which are used in the pulp and paper industry. In addition, synthetic fibers of the viscose rayon or regenerated cellulose type can also be used.
  • pigments and fillers may be added to the paper which is to be sized with our novel sizing agents.
  • Such materials include clay, talc, titanium dioxide, calcium carbonate, calcium sulfate, and diatomaccous earths.
  • Other additives, including alum, as well as other sizing agents can also be used with our sizing agents.
  • our sizing agents may be employed in amounts ranging from about 0.05 to about 5.0% of the dry weight of the pulp in the finished sheet or web. Within this range the precise amount which is to be used will, of course, depend for the most part upon the type of pulp which is being utilized, the specific operating conditions, as well as the particular end use for which the paper is destined. Thus, for example, paper which will require good water resistance or ink holdout will necessitate the use of a higher concentration of sizing agent than paper which will be used in applications where excessive sizing is not needed. These same factors also apply in relation to the amount of cationic agent which may be used in conjunction with our sizing agents.
  • our reagents have been found to provide a degree of water resistance which is comparable, and in many cases superior, to the results obtained with other heretofore employed sizing agents. Moreover, our sizing agents impart a resistance to acid and alkali which is often unattainable with other sizing agents.
  • Example I This example illustrates the use of our sizing agents in the form of aqueous emulsions wherein the emulsifier used is a tertiary amine cationic starch derivative.
  • the use of our sizing agents in combination with alum is also illustrated.
  • the water resistance of the resulting paper is compared with that of paper which had been sized with mixtures of fortified rosin and alum.
  • IODSA aqueous emulsion of iso-octadecenyl succinic acid anhydride which for purposes of brevity will hereinafter be referred to as IODSA, was prepared by first cooking 7.5 parts of the beta-diethyl amino ethyl chloride hydrochloride ether of corn starch, whose preparation is described in Example I of US. Patent 2,813,093, in 85 parts of water which was heated in a boiling water bath. After being cooked for 20 minutes, the dispersion of the cationic starch derivative was cooled to room temperature and transferred to a high speed agitator whereupon 7.5 parts of IODSA were slowly added to the agitated dispersion.
  • both the cationic agent and the IODS A were both the cationic agent and the IODS A.
  • the basis weight of these sheets was 55 lbs./ ream (24 x 36"500 sheets).
  • comparable sheets were made which contained varying amounts of IODSA as well as several which contained the IODSA in combination with varying amounts of alum.
  • the pH of the aqueous pulp slurry was 5.0.
  • the water resistance of these sheets was compared with that of sheets prepared from comparable pulp which had been sized with a mixture of rosin and alum.
  • the former test involves placing a small amount of uranine dye powder on the upper surface of a swatch of paper which is. then set afloat in distilled water. As the water is absorbed into the paper, the dye is moistened and thus becomes sensitive to ultraviolet light. The time, in seconds, required for this UV sensitivity to occur is thus in direct relation to the water resistance of the paper since a more water resistant paper will, of course, retard the moistening of the dye which has been placed upon its upper surface.
  • the ink dip test is a qualitative comparison wherein a swatch of the paper being tested is dipped into a 1:1 mixture of water and blue ink. The swatch is then removed, washed with water and the remaining color evaluated with a colorimeter. Thus, a swatch with a greater degree of water resistance will have a lighter color than a swatch with poor water resistance. For this test an arbitrary color scale of 1-10 was used, with #1 indicating .the least color or the best water resistance, and the #10 indicating the most color or the poorest water resistance. This test also provides a qualitative visual indication of the distribution of the sizing agent in the paper.
  • a series of aqueous emulsions of IODSA were prepared by means of the procedure described in Example I wherein the same tertiary amine cationic starch described therein was again used as the emulsifier.
  • These emulsions contained varying amounts of both the IODSA and the cationic starch and, with agitation, they were added, at the headbox, to separate batches of bleached sulfate pulp having a fireeness of 500 and a consistency of 0.5

  • the basis weight of the resulting paper was 60 lbs/ream. Below are described the compositions of the various sheets which were prepared as well as the results obtained when the Water resistance of these sheets was tested by means of the uranine dye test.
  • Example III This example illustrates the use of octenyl succinic acid anhydr-id-e.
