Definitions

  • the invention relates to means for sizing paper, cardboard and cardboard, a method for producing these means and their use.
  • the pseudo-neutral sizing behavior has the disadvantages that on the one hand it is cost-intensive due to the use of sodium aluminate and on the other hand the pH value in the fabric has to be kept exactly.
  • Neutral sizing uses a reactive substance (e.g. ketene dimers) or a cationic plastic dispersion as the sizing agent.
  • a reactive substance e.g. ketene dimers
  • a cationic plastic dispersion as the sizing agent.
  • Disadvantages with this method include sensitivity to alum and other aluminum-containing salts, against lignin and contaminants in the waste paper, the high amount required and the always observed maturing of the sizing.
  • the so-called surface sizing is a finishing variant of the mass sizing of glued or not sized paper.
  • the process of subsequent surface sizing results in a surface improvement for use as writing and printing paper, which is shown, for example, in improved ink and eraser resistance and improved gloss.
  • rosin is preferably used in the form of resin soap and resin dispersions, which are added to the liquid fiber material and are then precipitated as aluminum resinate by adding aluminum compounds.
  • natural and synthetic products are used, which are applied to the paper fibers and give the paper a water-repellent effect.
  • the natural products are rosin, animal glue, starch.
  • the synthetic products are copolymers of styrene and acrylic ester, alkyl succinic anhydride, alkyl ketene dimers.
  • Synthetic products are predominantly known as sizing agents from the new prior art.
  • EP-B2-0 200 002 discloses a paper sizing agent and its use which consists of a conventionally reinforced rosin dispersion and polyaluminium hydroxychlorides and optionally contains agents such as polyamine or polyamide-epichlorohydrin resins.
  • EP-B1-0 074 544 describes a glue dispersion which, as a continuous phase, contains an aqueous solution of at least one dispersant for resin glue, for example polyamine, polyamide-epichlorohydrin resin contains and contains as the dispersed phase finely divided particles of a hydrophobic cellulose-reactive glue such as alkyl ketene dimers and finely divided particles of fumaric acid-reinforced rosin resin (eg tall resin). These can only be produced by extreme shear forces with the help of a homogenizer. They do not contain polyaluminium hydroxychloride, but require at least one water-soluble, nitrogen-containing cationic dispersant.
  • the resinous reaction products of epichlorohydrin with aminopolyamides etc. are preferably used.
  • WO 86/02677 describes a glue emulsion / dispersion consisting of unsaponified resin acid in an aqueous phase, a dissolved polyaluminium salt and preferably a cationic organic component such as e.g. Washing emulsions, polyamines, cellulose derivatives or polyacrylates. Resin sizing is carried out at low pH values (pH ⁇ 5).
  • EP-B-0 292 975 discloses the use of an emulsion of an alkyl ketene dimer glue in combination with a cationic rosin glue and an insolubilizing agent, preferably alum, in a process for producing cardboard for certain containers and a process for the production of such containers.
  • a cationic rosin size and the insolubilizing agent are preferably mixed before use.
  • the agent for insolubilizing the rosin resin is, however, only added later in the usual way; see. Page 3, lines 49 to 53.
  • Alum is preferably used as the precipitant and not previously mixed with polyaluminium hydroxychloride.
  • EP-0 275 851 describes an aqueous dispersion whose dispersed phase contains a homogeneous mixture of resin material and a synthetic sizing agent, preferably ketene dimerate, and a polyaluminium compound with at least four aluminum atoms.
  • This process for the preparation of the dispersion has the disadvantage that the dispersion or the homogeneous mixture of rosin and ketene dimerate is very complex to manufacture and therefore expensive.
  • DE 43 06 557 describes a composition for the surface sizing of paper and cardboard containing an aqueous dispersion of 1 to 40% by weight of rosin resin and 1 to 5% by weight of protective colloid and / or surfactant.
  • Tall, balsam or root resin are mentioned as rosin resin.
  • Polyacrylamide, urea derivatives, acrylic acid derivatives, etc. are mentioned as cationic polymers.
  • No. 4,522,686 describes a sizing agent for mass and surface sizing for paper, which contains a dispersion of a ketene dimer, a reinforced resin and water-soluble, nitrogen-containing cationic dispersing agents.
  • EP-A2-0 357 866 describes a cationic sizing agent for paper which also has an excellent sizing effect for surface sizing.
  • the sizing agent consists of a stable, aqueous, colloidally dispersed solution of a salt of a copolymer consisting of N, N-dimethylaminoalkyl acrylate, meth / acrylic acid ester of a fatty alcohol and concentrations of methacrylate and methacrylic acid.
  • EP-O 257 412 also describes a sizing agent for paper containing a dispersion of copolymers of acrylonitrile and acrylic acid esters of an alcohol. This composition can be used as a surface sizing agent for paper.
  • the invention has therefore set itself the task of providing an inexpensive, environmentally friendly and easy to produce agent for mass and surface sizing of paper, cardboard and cardboard.
  • the process for the production of sized papers should be carried out using means known per se and should be able to be carried out inexpensively.
  • the object of the invention is surprisingly simply achieved by a means for gluing paper, cardboard and cardboard consisting of 5 to 75% by weight dispersions of alkyl ketene dimers and 25 to 95% by weight of a cationic resin glue, the cationic resin glue being made from a rosin -Dispersion and polyaluminium hydroxychlorides.
  • the agent can be used both as a mass and as a surface sizing agent.
  • the agent is liquid and is in dispersion form.
  • objects of the invention are the method according to claim 2 and the use according to claim 3.
  • Rosin resins such as tall resin, balsam resin or root resin are used as the cationic resin glue, and the resin can be partially saponified or unsaponified.
  • rosin dispersions are preferably used, such as the rosin resin Kentosol AP® according to EP-B 0 200 002.
  • dispersions either conventionally unreinforced dispersions made of rosin resin or the conventionally reinforced resin glue dispersions made from maleic anhydride are used. or fumaric acid-modified rosin or hydrocarbon resin with the addition of protective colloids or surface-active substances.
  • rosin dispersions with a solids content of 10 to 50 wt .-% have the advantage that they are made on a natural resin basis and are therefore environmentally compatible and recyclable. Compared to the polymers or synthetically produced sizing agents are characterized by a significantly better price / performance ratio.
  • protective colloids such as casein, soy protein, polyvinyl alcohol, polyvinyl pyrrolidone, carboxymethyl cellulose, starch, collagen, manogallactans and alginates are used as protective colloids.
  • Alkylbenzyl sulfonates, alkylphenol polyglycol ethers, alkylphenol polyglycol sulfonates, phosphoric acid esters, alkyl polyglycol sulfosuccinates for dispersing the rosin can be used as the surface-active substance (surfactants).
  • aqueous dispersions additionally contain commercially available polyaluminium hydroxychloride. They are used instead of alum and serve as precipitants.
  • cationic polymers can also be included.
  • additives generally consist of aqueous solutions or dispersions, for example of polyacrylamide, polydialkyldimethylammonium chloride, polyethyleneimines, polyaminepichlorohydrin resin, polyamidepichlorohydrin resin, melamine-formaldehyde resin, urea-formaldehyde resin, polydicyandiamine-formaldehyde resin and furthermore cationic methacrylic acid, styrene, acrylic ester, acrylic polymers, styrene, acrylic ester copolymers from styrene, Methacrylic acid, acrylic acid, N, N-dimethylaminomethacrylate.
  • ketene dimer glues are added to the cationic resin glues.
  • these ketene dimers have the advantage that they are resistant to lactic acid, they show incompatibilities with alum and aluminum-containing salts.
  • sizing in the neutral to weakly alkaline pH range can only be carried out with alkyl ketene dimers.
  • the sensitivity to aluminum-containing salts is not observed in the agent according to the invention.
  • the mixture according to the invention of cationic resin size and alkyl ketene dimers with the usual additives gives a paper size which can be used in a wide pH range, is environmentally compatible and is easy to produce.
  • the pH insensitivity is so great that even the addition of alum does not interfere, although according to the invention the use of alum can be dispensed with.
  • the production of the product according to the invention is relatively simple. It can be done, for example, by introducing the individual components into a stirred tank.
  • 100 parts by weight of the resin dispersion according to 1) are mixed with 100 parts by weight of water, and then 200 parts by weight of polyaluminum hydroxychloride with an Al 2 O 3 content of 10% are added with vigorous stirring. After the polyaluminium hydroxychloride addition has ended, the mixture is stirred for a further half an hour. A further 10 parts by weight of a 12.5% strength polyamidoamine-epichlorohydrin resin solution (such as, for example, Luresin KN from BASF) are then added. After stirring for half an hour, a stable cationic resin dispersion is obtained.
  • the order of addition of the three components in the cationic resin dispersion can be varied as desired.
  • AKD emulsion 100 parts by weight of an aqueous solution with 5% cationic starch and 1% lignosulfonate sodium is mixed intensively at 60 to 70 ° C. with 15 parts by weight of a melted AKD wax (made from a mixture of palmitic and stearic acids). The mixture is then homogenized with a homogenizer under high pressure. With the addition of further water and the pH adjustment with sulfuric acid, the AKD emulsion is brought to a concentration of 10% and a pH of 3 to 4.
  • synthetic polymers or surface-active substances can also be used to produce AKD emulsions.
  • Examples include: polyacrylamide, dicyandiamide-formaldehyde resin, fatty alcohol ethoxylates, polyamine-epichlorohydrin resin, polyalkylamine-epichlorohydrin resin, glycerol stearates.
  • the product according to Reference Example 2 is mixed with the product according to Reference Example 3 in a ratio of 3: 1 with stirring.
  • the mixture obtained is stable in storage and can be used diluted or undiluted for sizing paper, cardboard both in bulk and on the surface of the finished paper or cardboard.
  • the mixing ratio is variable over a wide range. Further additions of cationic products such as polyamidoamine-epichlorohydrin resin, dicyandiamide-epichlorohydrin resin, polyacrylamide are possible and can improve the sizing.
  • the commercial product Flexsize 114 from the holder of European patent application 0 074 544 was compared with two commercial products according to the invention from the patent owner, namely Kentosol KF 1 and Kentosol KF 2.
  • the almond product Flexsize 114 contains 15 to 20% rosin resins, 2 to 5% alkyl ketene dimers and 5 to 8% alum. It also contains a quantity of water-soluble nitrogen-containing cationic dispersants which is difficult to quantify.
