Definitions

  • This invention relates to a process for controlling natural pitch deposition obtained from the processing of various wood pulps which are then used to manufacture paper products. These natural pitch depositions are detrimental to efficient operations of paper mills. Pitch deposits on process equipment used in the paper making systems result in operational problems related to the accumulation of pitch deposits on consistency regulators and other instrumental probes used to monitor the process of manufacturing paper from various types of pulp and paper furnishes.
  • pitch deposits can form on screens and can reduce throughput as well as upset the operation of the paper manufacturing process.
  • the deposition of natural pitch can occur not only on the metal surfaces in the system but also on plastic and synthetic surfaces such as machinery wires, felts, foils, UHLE boxes, and head box components. These pitch deposits may also break off resulting in spots and defects in the final paper product which thereby decreases the paper quality.
  • anionic polymers and co-polymers of anionic monomers and hydrophobic monomers have been used extensively to prevent pitch deposition.
  • anionic polymers and co-polymers of anionic monomers and hydrophobic monomers have been used extensively to prevent pitch deposition.
  • the above types of polymers are described for this purpose.
  • the present invention provides an improved process of pitch control which process uses as a pitch control agent, water soluble co-polymers or terpolymers which are formed by polymerization of diallyl dimethyl ammonium salts with acrylic acid or methacrylic acid or their salts, and optionally using various alkyl acrylate esters or hydroxy substituted alkyl esters of acrylic acid or methacrylic acid.
  • Another object of the invention is to eliminate or minimize the effect of natural pitch deposits in the manufacture of paper by adding to a pitch contaminated paper furnish prior to sheet formation, an improved pitch control agent which agent is a co-polymer or terpolymer containing diallyl dimethyl ammonium salts, acrylic acid or methacrylic acid and its salts, and, optionally, alkyl acrylate or hydroxy alkyl acrylates.
  • Another object of the invention is to provide a specific co-polymer and/or terpolymer which is useful as a pitch control agent which polymer has a molecular weight ranging from about 10,000 to about 1,000,000 and contains from 75 - 95 mole per cent of diallyl dimethyl ammonium chloride; contains from about 2 to about 25 mole per cent of acrylic acid, methyacrylic acid, or their salts, or mixtures thereof; and from about 0 to about 10 mole per cent of an alkyl acrylate or a hydroxy alkyl acrylate or mixtures thereof.
  • the polymer structure is as that described above.
  • each monomer unit is essentially randomly distributed along the polymer chain and the polymer is ampholytic in nature, i.e. it can carry both a positive and a negative charge.
  • the polymer optionally contains from 0 to about 10 mole per cent of a monomer which is oleophillic in character.
  • This oleophillic monomer is preferably an ester or hydroxyester of acrylic acid, methacrylic acid, ethacrylic acid, or mixture thereof.
  • the cationic character of the polymers described above are provided by inclusion of from about 75 to about 95 mole per cent of diallyl dimethyl ammonium salts.
  • diallyl dimethyl ammonium salts may be chlorides, bromides, iodides, sulfates, nitrates, phosphates, and the like.
  • these quaternary di-vinyllic salts are in the form of diallyl dimethyl ammonium chloride (known in abbreviation as DADMAC).
  • DADMAC diallyl dimethyl ammonium chloride
  • the diallyl dimethyl ammonium chloride (DADMAC) monomer is contained in the polymer at from about 75 to about 95 mole per cent, preferably from about 80 to about 90 mole per cent, and most preferably between 85 to about 90 mole per cent. This provides for an overwhelming positive charge on the backbone polymer.
  • an anionic monomer unit is chosen from acrylic acid, methacrylic acid, ethacrylic acid, and their common salts, or mixtures thereof.
  • the salts are in the form of alkali metal salts, equivalent amounts of alkaline earth metal salts, or salts of ammonium cations, quaternary amine cations, or protonated amine cations.
  • anionic monomer is acrylic acid, or methacrylic acid, or mixtures thereof, used either as the free acid or as the sodium, potassium, and/or ammonium salts.
  • anionic monomers can be represented by the term (meth)acrylic acid, but this term is used herein to represent any vinylic acid, or vinylic acid salt having the structure: where R is H, CH 3 , C 2 H s , and mixtures therof; and M is as defined above.
  • the polymer can be improved by the incorporation, optionally, of certain oleophillic monomers such as (meth) acrylic acid esters, or (meth)acrylic acid hydroxy esters.
  • oleophillic monomers such as (meth) acrylic acid esters, or (meth)acrylic acid hydroxy esters.
  • These compounds provide some oleophillic character to the polymer and can assist in accumulating and dispersing pitch particles and attaching these pitch particles to cellulosic fibers so they do not accumulate disadvantageously on paper machine surfaces or cause difficulties otherwise in the manufacture of paper.
  • These vinylic acid esters and vinylic acid hydroxy esters are primarily those materials chosen from acrylic acid esters, methacrylic acid esters, or ethacrylic acid esters.
  • acrylic acid ester, methacrylic acid ester, or ethacrylic acid ester we mean to also include the hydroxy esters that contain one or more hydroxyl groups on the alkyl unit attached to the ester oxygen.
  • the polymer that is preferred is a polymer that has a molecular weight ranging from about 10,000 to about 1,000,000 and most preferably has a molecular weight ranging from about 50,000 to about 500,000. These molecular weights are weight average molecular weights.
  • the most preferred polymer contains from about 80 to about 90 mole per cent of diallyl dimethyl ammonium chloride, from about 5 to about 20 mole per cent of acrylic acid or methacrylic acid or mixtures thereof, (or salts thereof) and from about 0 to about 10 mole per cent of acrylic acid esters chosen from the group consisting of hydroxy alkyl acrylates and alkyl acrylates, or mixtures thereof, where the alkyl group of the ester functionality has from about 1 to about 24 carbon atoms, preferably from about 2 to about 14 carbon atoms.
  • ampholytic polymers of this invention do not necessarily have to contain the (meth)acrylate esters or hydroxy alkyl (meth) acrylate esters, but can be formed merely as co-polymers of diallyl dimethyl ammonium chloride (or other salt) and either acrylic acid, methacrylic acid, ethacrylic acid, their salts, or mixtures thereof.
  • diallyl dimethyl ammonium chloride or other salt
  • acrylic acid methacrylic acid, ethacrylic acid, their salts, or mixtures thereof.
  • DADMAC is present between about 80 to about 95 mole per cent and the anionic (meth)acrylic acid units are present at between about 5 to about 20 mole per cent.
  • these co-polymers contains about 80 to 90 mole per cent DADMAC and from about 10 to about 20 mole per cent (meth)acrylic acid, or its salts.
  • dosages of products containing the pitch control agents described above normally range from about 0.05 to about 20 pounds of formulated product per ton of paper product, on a dry fiber basis.
  • the pitch control agents normally are provided as liquid dispersions or solutions of the polymers described in water which products normally range from about 1 to about 40 weight per cent active polymer.
  • the polymer may also be provided as a water-in-oil latex emulsion containing a dispersed aqueous phase in which the polymer described above has been dissolved.
  • This emulsion normally also contains a controlled HLB surfactant system such that when the water-in-oil emulsion is added to the paper making system, inversion of phases occurs, and the polymer is rapidly dissolved and dispersed in the aqueous paper making media.
  • the polymer content of the emulsion product can range from about 5 to about 55 weight per cent of the product.
  • the polymer dosage for the polymers of this invention, and described above normally ranges from about 0.05 to about 2.0 pounds per ton, on the basis of active polymer per ton of dry fiber.
  • Approximately 7,000 ml of a hardwood kraft paper stock was prepared. This hardwood kraft stock contained 2.27 weight per cent fiber. This paper stock material was diluted with water until it contained approximately 1.5 weight per cent hardwood kraft stock fiber. The pH of this stock was adjusted to about 10.6 with sodium hydroxide solution. Approximately 100 ml of a 1 per cent dispersion of a laboratory pitch mixture was added to 700 ml of the 1.5 per cent hardwood kraft stock. The pH dropped to a pH of approximately 7.4-7.5. To this pitch containing slurry of hardwood kraft fibers was added 5 ml of a 0.5 molar calcium chloride dihydrate solution. This mixture was gently stirred and the pH checked. The pH had dropped to approximately 6.5. The pH of this test preferably ranges somewhere between 5.5 and 7.0 during the testing sequence for pitch deposition control.
  • the mixture of hardwood kraft stock, which mixture contains synthetic pitch dispersion and calcium chloride as described above is then poured into an laboratory blender.
  • a preweighed poly tetrafluoro ethylene plastic (PTFE) coupon which acts as a surface on which pitch is accumulated.
  • This PTFE coupon is added to the pitch contaminated hardwood kraft stock in the blender.
  • the blender used had 14 buttons controlling agitation blade speed.
  • button number 4 is pushed and the stock is agitated for three minutes. Other blender speeds are also operable.
  • a pitch deposit is obtained on the PTFE coupon, and after the coupon is removed, rinsed with distilled water from a wash bottle and dried in air, the coupon is then weighed. Drying time can range from about 4 hours to about 24 hours. The amount of deposited pitch is calculated by the difference from the original weight of the coupon.
  • test polymers were treated in the laboratory using the procedures set forth in Example I, except that a modified synthetic laboratory pitch was used.
  • the pitch dispersion used is a synthetic laboratory pitch comprising a mixture of fatty and resin acids and esters, sterols, sterol esters and fatty alcohols, which is representative of actual softwood and/or hardwood pitch.
  • This synthetic pitch is used to form the 1 % dispersion described in Example I, and ranges in content as described in Table V.
  • This synthetic laboratory pitch is dispersed in isopropanol to form a
