Definitions

  • the invention relates to the use of a polyamide-polyamine-epichlorohydrin precondensate as an impregnating agent for paper.
  • thermosetting resin A curable aqueous solution of a thermosetting resin has become known from US Pat. No. 4,336,835, which has a relatively high solids content and allows improved wet strength of paper to be achieved.
  • the solution is prepared by reacting an aliphatic dicarboxylic acid with a polyalkylene polyamine to form a polyamide polyamine, which is then reacted with epichlorohydrin.
  • the first reaction is present at a molar ratio between aliphatic dicarboxylic acid and polyalkylene polyamine of 1: 1.0 to 1.2 executed until a viscosity of 50% aqueous solution at 25 ° ° C of polyamide-polyamine 4-10 dyn.s.cm ⁇ 2 (400 to 1000 cP) is reached, and the second reaction, in which epichlorohydrin is used in an amount of 1.6 to 1.7 moles per mole of the polyamide secondary amine, is as long continued until the viscosity of the 15% solution of the resulting product at 25 ° C reaches a value of 0.3 to 1.5 dyn.s.cm ⁇ 2 (30 to 150 cP).
  • Adipic acid recommended and as polyalkylene-polyamine triethylene tetramine.
  • polyamide-polyamine-epichlorohydrin precondensate the degree of condensation of which is 500 and corresponds to an active content of 12%
  • lignosulfonic acid optionally as the calcium salt of sulfonic acid
  • Additive to the impregnation liquid for the surface treatment of paper, in particular corrugated raw paper is used.
  • the measure according to the invention mentioned above as an additive to the impregnation liquid, it was possible to achieve adequate swelling resistance and an increase in the strength values of the paper, in particular the CMT value (DIN 53143).
  • the chlorine component of the pre-condensate does not pose any difficulties with regard to environmental pollution, because chlorine reacts with the calcium contained in the sulfite waste liquor to form CaCl2 and no free chlorine or hydrochloric acid is formed.
  • the polyamide-polyamine-epichlorohydrin precondate can be constructed from the basic materials adipic acid, triethylene tetramine and epichlorohydrin so that an average molecular weight of 20,000 with a chlorine content of 16-18%, preferably 17%, a condensation temperature of 180 ° C. and a reaction time of 45 min results.
