  • US Pat. No. 3,966,654 describes aqueous dispersions which consist essentially of reinforced rosin, a water-soluble, cationic, resin-based dispersant and water.

  • European patent 0 056 876 describes aqueous dispersions which consist essentially of reinforced rosin, a water-soluble or water-dispersible cationic starch-based dispersant, an anionic surface-active agent and water. Two processes are described for the preparation of these dispersions: firstly, the dispersion from a solution of the resin in an organic solvent (methylene chloride is used in the examples) can be carried out by evaporating the solvent in vacuo, or secondly by directly mixing the hot, molten resin with Emulsifier and starch solution in one dispersant at high temperatures and high shear forces.

  • European patent specification 0 200 002 claims rosin-based paper sizes, which are characterized in that the cationization of a stable anionic size with polyaluminium chloride and optionally with the addition of a cationic polymer.
  • International publication WO 90/08852 also describes a process for producing a cationic glue by adding polyaluminium chloride to a stable dispersion of rosin reinforced with maleic anhydride. Both processes have in common that they start from a stable aqueous dispersion which must therefore contain a relatively high proportion of emulsifier, which can have a negative effect on the sizing and the cationization behavior.

  • the implementation of the rosins with ⁇ , ⁇ -unsaturated carbonyl compounds is based on an adduct formation according to Diels-Alder with a suitable structure in the rosin resin and should increase the yield of the sizing agent.
  • the rosins thus modified can then e.g. can be processed into dispersions by a reverse process.
  • German Offenlegungsschrift DE 37 08 854 A1 describes a sizing agent for use in the neutral range, which is an aqueous dispersion of a rosin or reinforced rosin esterified with at least one polyhydric alcohol consisting of carbon, hydrogen and oxygen. If a very good retention system is present, this sizing agent shows good gluing effect in the neutral range when using bleached sulfate pulp, but fails completely when using so-called "difficult substances" such as e.g. Sulphite pulp, wood pulp, waste paper, TMP, CTMP, etc.
  • German published application DE 44 12 136 AI describes a sizing agent made from reinforced rosin esterified with triethanolamine and dispersed with an emulsifier system consisting of sodium lignin sulfonate and cationic starch.
  • This sizing agent is for the mass or surface sizing of paper in a pH range of 4
  • European patent specification 0 259 671 B1 describes an aqueous dispersion of a sizing agent made from reinforced, unreinforced, hydrogenated or disproportionated rosin, optionally esterified with amino alcohol, which is dispersed with a dispersant containing digested casein and cationic starch.

  • Carbonyl compounds reinforced and rosin resins esterified with tertiary amino alcohols can also be used for neutral sizing in the pH range above 7 with chalk or precipitated calcium carbonate (PCC) as filler.
  • these resin size dispersions are anionic dispersions with saponified resin as emulsifier and casein as stabilizer, which were prepared by the known inverse process.
  • the Harzleimdispersionen above show compared to the rosin sizing agents based on non-esterified, ie mei ⁇ least with ⁇ , ß-unsaturated carbonyl compounds reinforced resins have superior properties in the sizing in the neutral range with chalk or PCC as a filler.

  • the sizing agent thus obtained is said to be compatible with inorganic, aluminum-containing fixing agents.
  • This goal is achieved in that in a first step a metastable dispersion of the resin is produced with the aid of a minimized amount of a synthetic emulsifier, this dispersion is immediately cooled and only then converted into a stable dispersion in the cold with the corresponding polymer solution or polymer dispersion.
  • the polymer solution stabilizes the dispersion.
  • the resin used can be both a rosin compound and a rosin compound reinforced with formaldehyde and / or ⁇ , ⁇ -unsaturated carbonyl compounds, as well as other rosin reaction products.
  • the emulsifier used can be anionic, cationic or nonionic.
  • rosin refers to rosin, tall resin, wood resin and root resin or mixtures of these resins.
  • modified resins suitable according to the invention also include, for example, hydrogenated resins or disproportionated resins.
  • the cationic polymer is neither exposed to high temperatures nor high shear forces by the process according to the invention. As a result, the quality of the starch remains consistently high and its maximum retention effect is retained.
  • emulsifiers are capable of affecting the effectiveness of sizing agents. This will o prevented by using minimal amounts of emulsifier. In addition, larger amounts of emulsifiers in use can lead to problems with foaming.
  • the resin size dispersions thus obtained can be mixed in any ratio with dispersions or emulsions of synthetic sizes (for example alkenylated succinic anhydride, alkyl ketene dimer or carbamoyl chloride), which results in the combination of the sizing effects of both product components.
  • the dispersions according to the invention can consist in the disperse phase of particles which contain a mixture of rosin and synthetic sizing agent, or consist of particles of rosin and particles of synthetic resin material.
  • resins which are esterified with polyhydric alcohols for example tertiary amino alcohols, can also be used for the preparation of the dispersions according to the invention. These bring improved sizing effects in the pH range from 6 to 7.5.
  • All dispersions according to the invention can be mixed with aluminum-containing fixatives, which results in a further improvement in the retention of the sizing agent.

Abstract

L'invention concerne des dispersions aqueuses d'agent d'encollage de papier destinées à l'encollage de pâte et de surface. Ces dispersions contiennent des résines de colophane ou des composés dérivés de résines de colophane, une quantité minimale d'un émulsifiant anionique, cationique ou non ionique, un polymère ajouté ultérieurement et destiné à stabiliser la dispersion, éventuellement un agent de fixation contenant des ions d'aluminium, éventuellement un agent d'encollage synthétique et éventuellement une matière de charge. L'invention concerne également un procédé de préparation de cette dispersion. Les nouvelles dispersions conviennent au finissage du papier et du carton. Selon ce procédé de production des dispersions aqueuses d'agent d'encollage de papier, on prépare, dans un premier temps, une dispersion métastable d'une résine de colophane ou d'un composé dérivé à l'aide d'une quantité minimale d'un émulsifiant synthétique. Cette dispersion est immédiatement refroidie puis transformée par réaction avec une solution polymère ou une dispersion polymère à de basses températures en une dispersion stable.
