Definitions

  • the invention relates to a liquid, water-based adhesive concentrate, in particular with a polyhydroxy compound and / or a polyvinyl ester compound as an adhesive component, and to an adhesive which can be produced, for example, from this concentrate.
  • the invention also relates to a method for producing an adhesive for bonding at least two layers of material, in particular layers of paper, by dilution.
  • the invention further relates to an adhesive concentrate which, inter alia, is suitable for producing such an adhesive.
  • Paper layers in particular tissue paper layers, are usually produced by merging, embossing and laminating two or more paper layers.
  • Conventional production methods are the "nested and bossed” and the "foot to foot” method, which are carried out on machines, for example the PCMC (Paper Converting Machine Company).
  • PCMC Paper Converting Machine Company
  • Known adhesives for layer bonding in Germany have so far been mainly cellulose derivatives, for example cellulose ethers.
  • the adhesive to be processed is normally produced directly by the adhesive processor.
  • a pulverulent cellulose derivative such as methyl cellulose
  • methyl cellulose is stirred into water to produce an up to 10%, preferably 3-5% solution, which is then processed.
  • adhesives based on polyvinyl alcohol are also used. These adhesives contain polyvinyl alcohols in partially saponified form. These are polyvinyl alcohols, which are produced by saponification of polyvinyl acetate. The polyvinyl alcohol ester contains 87-90% PVOH and 10-13% PVAC. These adhesives may not like the corresponding cellulose products will set off a powder by the consumer r but must be obtained from the adhesive manufacturer as a liquid product. This leads to higher costs, which the adhesive consumer has to bear. For economic reasons, some adhesive manufacturers are trying to develop a liquid concentrate based on polyvinyl alcohol. Such concentrates can be diluted by the processor in a ratio up to a maximum of 1: 3 to consumption strength.
  • PVOH adhesive advantages are e.g. in higher adhesive strength with low viscosity and clean machine operation. Disadvantages, however, are the high costs and the sometimes too high adhesive strength when the viscosity is too low.
  • the viscosity of a concentrate should not exceed 30000 mPa »s so that it remains sufficiently easy to handle.
  • the finished, diluted adhesive solution should be sufficiently viscous in order to ensure trouble-free machine operation and sufficient water retention during bonding.
  • Solids contents of preferably 2.5 to 5% (PVOH) and
  • An advantage of the invention is that the adhesive concentrate can be diluted up to a ratio of 1:10 and more. Compared to cellulose derivative solutions, the lengthy production of the adhesive is reduced to a few minutes. The desired higher viscosity for processing can then be set by activating the "latent" thickener contained in the concentrate. Another advantage of the method according to the invention is the possibility of almost any adjustment or regulation of the viscosity of the adhesive after the dilution step. The process thus enables the production of an adhesive with a high dilution ratio and the viscosity required for any processing.

They are used, among other things, to stabilize liquid detergents, floor cleaners and the like, and to increase the viscosity of solvent mixtures or solutions of surface-active substances.
  • This acrylate acid polymer is latent until the addition of an activating reagent, i.e. contained in the adhesive concentrate at a very low degree of viscosity.
  • a base is added to the diluted adhesive solution for activation.
  • any strong base can be used, preferably ammonia or sodium hydroxide.
  • the acrylic acid polymer is neutralized by the base and thus activated, i.e. the adhesive solution becomes more viscous.
  • the viscosity of the adhesive solution is variable and depends, among other things. depends on the setting of the pH value.
  • the method according to the invention enables the production of an adhesive in which the viscosity, solids content and adhesive strength (as required) can be varied.
  • the properties of the adhesive solution can thus be selected by specifying the degree of dilution of the adhesive and the amount of base added, which neutralizes and activates an equivalent amount of acrylic acid polymer.
  • the adhesive solution can subsequently be raised to a higher viscosity, which is necessary, for example, for processing the adhesive.
  • the method according to the invention thus enables the production of an adhesive which, owing to an increased dilution ratio, is less expensive than the conventional adhesives and which avoids the disadvantages of the known adhesives with regard to the processing properties.

Abstract

L'invention concerne un procédé de fabrication d'un adhésif destiné à coller des couches de papier, selon lequel un adhésif concentré est tout d'abord dilué selon un rapport de 1:10 et ensuite mis en réaction avec un réactif activant, notamment une base. L'invention concerne en outre un adhésif concentré utilisé dans la fabrication de ce type d'adhésif. L'adhésif concentré contient un constituant polyhydroxy ou un composé d'ester polyvynilique et un épaississant, notamment un polymère d'acide acrylique. L'adjonction d'une base à l'adhésif concentré dilué permet de neutraliser l 'épaississant et de le rendre actif. Il est ainsi possible d'ajuster la viscosité de l'adhésif et de l'adapter à chaque type d'utilisation. Le procédé selon l'invention est d'un coût avantageux et permet d'obtenir un adhésif dont la viscosité, la teneur en matières solides et l'adhésivité sont variables. Il est particulièrement indiqué pour la fabrication de couches de papier de soie, de préférence le papier à usage ménager et le papier hygiènique.
