Definitions

  • the present invention relates to paper sizing agents based on rosin dispersions and their use for the production of sized papers, cardboards and cardboard as well as a process for the production of sized papers.
  • a process for sizing paper is known from EP-A 0 099 547, in which aluminum polyhydroxychloride is used for the aqueous suspension of the fibers with the rosin dispersion and calcium carbonate can be used as filler. This process is carried out in the pH range of at least 7.
  • EP-A 0 133 902 discloses a process for sizing paper, in which a synthetic sizing agent is added to the cellulose fibers, and a filler which is sensitive in the acidic range, aluminum polyhydroxychlorides being used as retention agents. In this process too, the aluminum polyhydroxychloride is only added after the fiber material has been homogeneously mixed with the sizing agent and the filler calcium carbonate.
  • rosin and polyaluminium hydroxychlorides are also known from CA-A 759 363, it being expressly recommended that the rosin and then the precipitant be added first. It is not advisable to add these substances in reverse order or even together to form a precipitate.
  • the object of the invention is to develop new paper sizing agents based on rosin dispersions which, on the one hand, are based on the customary and inexpensive raw material, rosin, and, on the other hand, can be used in various pH ranges of the material mass which occur in practice, so that can be worked without alum or other additional retention aids or fixatives.
  • the new paper sizing agents should also be able to be used with inferior material qualities such as waste paper and wood-containing materials and still lead reliably and easily to perfectly sized products.
  • the invention has also set itself the task of simplifying the process for the production of sized papers using rosin dispersions and polyaluminium hydroxychlorides as precipitants, and thereby being able to carry out the process more reliably and reproducibly.
  • the first object is surprisingly achieved by paper sizing agents, which are characterized in that they additionally contain polyaluminium hydroxychlorides and optionally retention and / or fixing agents and / or wet strength agents, the components being premixed while avoiding agglomeration.
  • the paper sizing agents preferably contain the polyaluminium hydroxychlorides in a commercially available aqueous solution with a content of 8 to 20% by weight of aluminum oxide.
  • the total mixture preferably contains 5 to 50% by weight of such polyaluminium hydroxychloride solutions.
  • the further object of the invention namely to improve a process for the production of sized papers using rosin dispersions and polyaluminium hydroxychlorides as precipitants, is achieved in that the rosin dispersions are mixed with the polyaluminum hydroxychlorides before use, avoiding agglomeration.
  • the rosin dispersions used are either conventionally unreinforced rosin resin dispersions or the conventionally reinforced resin glue dispersions which are prepared from rosin or hydrocarbon resin modified with maleic anhydride or fumaric acid, usually with the addition of protective colloids or surface-active substances.
  • the proportion of this resin size dispersion in the paper size according to the invention is 10 to 60% by weight, preferably 30 to 50% by weight.
  • These rosin dispersions are commercially available and usually have a solids content of 10 to 50% by weight.
  • the new paper sizing agents preferably already contain retention and / or fixing agents and / or wet strength agents.
  • These additives generally consist of aqueous solutions or dispersions, for example of polyamine-epichlorohydrin resins, polyamide-epichlorohydrin resins, polyacrylamides, polyethyleneimines, condensation products of formaldehyde with urea or dicyandiamide or melamine or mixtures of these solutions and dispersions.
  • the proportion of these additives is 1 to 20% by weight, preferably 4 to 15% by weight. These are also mostly commercial products.
  • the polyaluminium hydroxychlorides are also commercial products that have so far been used in particular for the precipitation and flocculation of dissolved constituents of waste water. According to the abovementioned patents, it is also possible to use them as a precipitant instead of alum or as a retention agent in the case of artificial sizing agents. However, considerable difficulties and disruptions have been shown in practical testing. Surprisingly, however, it has now been found that these polyaluminium chlorides can be added to conventional rosin dispersions without the resin flocculating or precipitating out or completely useless mixtures being formed. Surprisingly, such mixtures are able to glue paper, cardboard and cardboard correctly and differentially in a wide pH range. 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 paper sizing agents according to the invention are able to properly glue inferior starting materials such as waste paper and wood-containing fibers.
  • kaolin has primarily been used as a filler.
  • chalk i.e. Calcium carbonate used as a filler.
  • This filler is sensitive to alum and acid, so that it leads to undesired reactions, sticking, precipitation and other malfunctions.
  • waste paper it is increasingly to be expected today that considerable amounts of chalk are present in the product, which leads to the above-mentioned disturbances in the case of acid fixation.
  • the paper sizes according to the invention can be used without problems at least in the pH range between 3.5 and 9.0. They are preferably used in the neutral area, since experience has shown that this area produces the optimal mechanical properties of the sized paper.
  • the paper sizes according to the invention have the further advantage that they can be produced ready for use.
  • the new paper sizing agents are stable for a sufficiently long time and, if desired, can be diluted with water in any ratio.
  • the new paper sizing agents are less corrosive, they lead to reduced deposits on the screen, in the felts and the other machine parts and do not form any foam in the fabric system.
  • the paper sizing agents according to the invention are preferably metered continuously into the material stream shortly before the headbox of the paper or board machine. With this method of working it is possible to eliminate mechanical influences and to achieve a maximum sizing effect. This continuous dosage makes it possible to quickly influence the sizing effect if necessary.
  • the sizing can thus be set very differently from half-sizing to full-sizing.
  • 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.
  • the order of adding the components is not critical.
  • the rosin dispersion (resin glue dispersion) is preferably introduced and then the solution of the polyaluminium hydroxychloride is added tet.
  • the third and further components namely retention aid, fixative and wet strength agent, are added to the mixture simultaneously or in succession with further stirring.
  • the paper sizes according to the invention are liquid and are in dispersion form.
  • the products according to the invention for sizing paper, cardboard and cardboard are used in the mass of material.
  • the point of addition can be between pulper or Dutch until just before the headbox.
  • the amount used is usually between 0.5 and 2% solid resin based on dry fiber.
  • the degree of sizing that can be achieved is then between 15 and 35 Cobbeo.
  • a paper sizing agent is produced with the addition of 50 g of a dispersion of formaldehyde and aliphatic amides (Levogen PNK / Bayer) or fixing agent (FP / BASF).
  • the dispersion is stable for at least 6 weeks.
  • a paper sizing agent is produced with the addition of 50 g of polyethyleneimines (Polymin types / BASF).
  • the dispersion is stable for at least 6 weeks.
  • Sample sheets were produced to test the effectiveness of the products described in Examples 1 to 4.
  • a cellulose was used which consisted of 50% bleached sulfite pulp and 50% bleached sulfate pulp. This material was beaten with city water, ground to 40 ° SR and brought to 2% consistency. With the addition of 20% chalk as filler and a corresponding amount of sizing agent according to Examples 1 to 4, the sample sheets were produced using a Rapid-Köthen device. The Cobb method (60 seconds) was used to check the degree of sizing. The results are summarized in the table below.
