Definitions

  • the invention relates to the paper glue described in the claims for Bulk sizing and surface sizing.
  • Reinforced rosins can be made by reacting Maleic anhydride or other dienophilic compounds with rosin while increasing the number of carboxylic acid groups.
  • a typical reinforced glue can contain about 1 to 30% maleopimaric anhydride.
  • the rosin In the Bewoid process, the rosin is in the presence of 1 to 2% Sodium hydroxide and about 2% casein mechanically broken down. The rosin is heated and subjected to mechanical shear stresses until it is divided into small particles. A small amount of caustic soda is then added to the melted rosin to make it partially saponified and then casein is used to stabilize the dispersed Rosin added. The dissolved casein is mixed into the melted one with vigorous stirring Rosin incorporated, after which an additional amount of NaOH is added or the hot rosin melt is injected into water containing casein. Eventually Water was added to give a finished dispersion with about 30-45% solids, which is used in this form. This process is also called “inversion process Production of rosin glue "and the rosin glue thus produced as Designated "invert glue”.
  • the reinforced rosins have not previously been used Production of dispersions suitable, since they mostly had too high melting points, for Crystallization tended to form or formed fine crusts when dispersed Sedimentation symptoms led.
  • the patent describes a paper glue and a Process for its preparation in the form of an aqueous dispersion with a high content free rosin, in the reinforced rosin at elevated temperatures mixed with fatty acids, fatty acid mixtures and / or naphthenic acids and the dispersion in was carried out in a known manner. The method was used as an inversion method.
  • an anionic dispersant Materials based on saponified rosin, sodium alkylbenzosulfonate, Sodium naphthalene sulfonic acid, sodium lauryl sulfate or the ammonium salt of the sulfate ester an Akylphenoxy (poletylenoxy) ethanol used.
  • Swedish patent application 74 10 018-1 describes a practically stable, aqueous Dispersion consisting essentially of water, rosin material and as a stabilizer for the rosin material was an alkali metal alkyl benzene sulfonate.
  • the dispersions were prepared by passing a prepared mixture of the components through a Homogenizer led.
  • US-PS 39 06 142 discloses a means for gluing paper without using Aluminum sulfate, which is a stable aqueous dispersion of one by reaction with a alpha, beta-unsaturated carboxylic acid or an appropriate anhydride enhanced Rosin, a protective colloid, e.g. Casein and a volatile base, e.g. Ammonia, contained, with at least 90% of the reinforced rosin unsaponified.
  • a dispersing and Stabilizer made by using a measured amount of a protective colloid, e.g.
  • an invert glue for the mass sizing of paper which contained an aqueous dispersion of a reinforced rosin and its dispersant in solution anions of the formulas and in which R represents an n- or branched alkyl radical having 4 to 18 carbon atoms, R 4 represents an alkyl alkenyl or cycloalkyl radical with fused rings having 10 to 20 carbon atoms and n was such a number that something 27 to 75% of the molecular weight the CH 2 CH 2 O group.
  • protective colloids such as casein should not be necessary in the production of this well-known paper glue, but it had to be worked with hot inversion water.
  • an invert glue for mass sizing and surface sizing of paper which contains in the aqueous resin dispersion as a dispersant compounds which have anions of the formulas in solution or dispersion and where R is an n- or branched alkyl group having 8 to 9 carbon atoms and R 1 is an n- or branched alkyl or alkylene group having 12 to 20 carbon atoms and n is such a number that about 21 to 76% of the molecular weight is based on the OCH 2 CH 2 group are eliminated.
  • the sizing agents described above were in a pH range of 4.5-6 used and required relatively high amounts for fixation on the fiber Aluminum sulfate, which pollutes the wastewater.
  • the EPS 0200002 describes a process for neutral sizing with a One-component product that contains polyaluminium chloride and an invert glue. This Products cannot be stored for a long time because they are very thixotropic and therefore permanent should be stirred. Another disadvantage of these products is the small amount of resin, i.e. a lot of water is transported and the amounts used are very high - approx. 10% compared to 3% with previously known sizing agents.
  • All sizing agents that contain a protective colloid are metastable preparations that only have a limited shelf life and, if they contain casein, must be preserved.
  • the invention has for its object to provide a mass and surface glue for the pH range 4.5 - 8.5, which can be produced by a simple process and does not have the disadvantages of conventional invert glue.
  • the rosin used in the sizing agent according to the invention can be any of the Commercially available types of rosin, e.g. Root resin, balsam resin, tall resin and Mixtures of two or more of these resins in the raw or refined state. Resins with a tendency to crystallize at elevated temperatures with formaldehyde or Paraformaldehyde in the presence of an acid catalyst, e.g. p-toluenesulfonic acid in which Are known to those skilled in the art. So can resin treated with formaldehyde used and falls under the term "rosin resin" used here.
  • an acid catalyst e.g. p-toluenesulfonic acid
  • the amount of the acidic compound used is adjusted so that that a reinforced rosin with a content of about 1 to about 30% by weight, preferably about 5 to about 12% by weight of the added acidic compound based on the Weight of the reinforced rosin is obtained.
  • Manufacturing process reinforced rosins are described in U.S. Patents 2,628,918 and 2,684,300.
  • can be used to manufacture the reinforced rosin acid mixtures are used.
  • a mixture of the acrylic acid adduct to rosin and of the fumaric acid adduct to rosin Production of the resin glues according to the invention can be used.
  • esters of the named resins with amino alcohols e.g. Triethanolamine, triisopropanolamine, Tributanolamine or with glycerin, glycol or polyglycols for the production of Resin glue according to the invention suitable.
  • a polyglycol as an esterifying agent polyethylene glycols with a molecular weight of 190 are preferably used used until 1050.
  • the rosin can optionally be mixed with known additives, e.g. waxes, especially paraffin wax and microcrystalline wax, tall oil derivatives, fatty acids, especially C 12 -C 24 fatty acids, hydrocarbon resins including those derived from petroleum hydrocarbons and terpenes, spindle oils or polyglycols, or mixtures thereof.

  • tall oil derivatives especially paraffin wax and microcrystalline wax
  • fatty acids especially C 12 -C 24 fatty acids
